Answer:

Moshe made $1875 and Jamal made $5625

Step-by-step explanation:

divide it in half, then divde Moshe's half in half because he only made half as much,

hope this helps and remember to mark brainliest

Moshe furnishes $5000 and Jamal furnishes $2500 of the capital. Computed by solving the linear equation x + x/2 = 7500, where x is the capital furnished by Moshe.

Linear equations are an equation involving constants and variables, where variables are raised to a power of not greater than 1.

We are informed that Jamal and Moshe starts a business with a capital of $7500. Also, we are informed that Jamal furnishes half as much capital as Moshe does.

We will try to make a linear equation and solve for it to find the capital furnished by each of them.

Let the capital furnished by Moshe be $x.

Jamal furnishes half as much capital as Moshe does.

∴ Capital furnished by Jamal = 1/2 of Moshe's capital = 1/2 of $x.

∴ Jamal's capital + Moshe's capital = Total capital furnished

We know the total capital is $7500.

∴ Our linear equation is: 1/2 of $x + $x = $7500.

Now we solve this equation in the following ways:

or, (1/2)*x + x = 7500

or, x/2 + x = 7500

or, (x + 2x)/2 = 7500

or, 3x/2 = 7500

or, x = (7500*2)/3 = 15000/3 = 5000.

∴ x = 5000.

∴ Moshe's share = $x = $5000

Jamal's share = 1/2 of $x = 1/2 of $5000 = $2500.

∴ Moshe furnishes $5000 and Jamal furnishes $2500 of the capital. Computed by solving the linear equation x + x/2 = 7500, where x is the capital furnished by Moshe.

Answer:

(1, 6).

Step-by-step explanation:

The reflection of  the x coordinate of (1, 2) creates a point with y -coordinate

-1 - 3 = -4 while the x-coordinate  remains 1.

The point (1, -4) is now reflected about  y = 1, so  -4 translates to 1 + 5 = 6. and x stays at 1.

Answer:

Distance = 17.5 miles

Step-by-step explanation:

Note.

Given question is not complete

Given:

Speed upstream = x

Time taken in upstream = 3.5 hour

Speed in return trip = (x+2)

Time taken in return trip = 2.5 hour

Computation:

Distance = speed × time

Distance = x (3.5)

Distance = 2.5 (x+2)

Distance = 2.5x + 5

So,

2.5x + 5 = 3.5 x

1.5 x = 5

x = 5 miles/hour

Distance = x (3.5)

Distance = 5 (3.5)

Distance = 17.5 miles

Answer:

The number is -30.

Step-by-step explanation:

Given that,

Eight plus the quotient of a number and 3 is −2 . We need to find the number.

So, putting given condition into mathematical expression. Let the number is x. So,

[tex]8+\dfrac{x}{3}=-2[/tex]

Subtracting  on both sides,

[tex]8+\dfrac{x}{3}-8=-2-8\\\\\dfrac{x}{3}=-10[/tex]

Now cross multiplying, we get

x = -30

So, the number is -30.

Answer:

[tex]12-[20-2(6^2\div3\times2^2)]=88[/tex]

Step-by-step explanation:

So we have the expression:

[tex]12-[20-2(6^2\div3\times2^2)][/tex]

Recall the order of operations or PEMDAS:

P: Operations within parentheses must be done first. On a side note, do parentheses before brackets.

E: Within the parentheses, if exponents are present, do them before all other operations.

M/D: Multiplication and division next, whichever comes first.

A/S: Addition and subtraction next, whichever comes first.

(Note: This is how the order of operations is traditionally taught and how it was to me. If this is different for you, I do apologize. However, the answer should be the same.)

Thus, we should do the operations inside the parentheses first. Therefore:

[tex]12-[20-2(6^2\div3\times2^2)][/tex]

The parentheses is:

[tex](6^2\div3\times2^2)[/tex]

Square the 6 and the 4:

[tex](36\div3\times4)[/tex]

Do the operations from left to right. 36 divided by 3 is 12. 12 times 4 is 48:

[tex](36\div3\times4)\\=(12\times4)\\=48[/tex]

Therefore, the original equation is now:

[tex]12-[20-2(6^2\div3\times2^2)]\\=12- [20-2(48)][/tex]

Multiply with the brackets:

[tex]=12-[20-96][/tex]

Subtract with the brackets:

[tex]=12-[-76][/tex]

Two negatives make a positive. Add:

[tex]=12+76=88[/tex]

Therefore:

[tex]12-[20-2(6^2\div3\times2^2)]=88[/tex]

Answer:

she has 2 minutes to spare

Step-by-step explanation:

Answer:

21.37 days.

Step-by-step explanation:

Step 1

Find the total amount Nancy is paying for her iPhone

Cost of the phone = $899

Tax = 8.50%

Amount paid for tax = 8.5% × 899

= 8.5/100 × 899

= $76.415

Total amount Nancy is paying = Tax + Cost of the phone

= $76.415 + $899

= $975.415

Step 2

We are told in the question that Nancy had already saved $78

Hence, Totally amount left for Nancy to buy her iPhone = $975.415 - $78

= $897.415

Step 3

Nancy works at a car wash and earns $42 every day.

The number of days left for her to work in the car wash in order to buy her phone is calculated as:

$42 = 1 day

$897.415 = x days

Cross Multiply

= $42 × x = $897.415 × 1 day

x = $897.415/$42

x = 21.36702381 days.

Approximately, x = 21.37 days

Therefore, Nancy has to work for 21.37 days at the car wash to have enough money for her iphone

Answer:

  each of the 12 turns is 150°

Step-by-step explanation:

If we number the points of the star 1–12, in order for the star to be symmetrical, each point must connect to two points symmetrically located around the centerline.

That is, point 1 may connect to points {2, 12} or {3, 11} or {4, 10}, or {5, 9} or {6, 8} or {7, 7}. For each of these connections, the angle made at the point of the "star" is, respectively, 150°, 120°, 90°, 60°, 30° or 0°. For these angles, the figure obtained will be ...

  150° - dodecagon, a 12-sided figure

  120° - hexagon

  90° - square

  60° - equilateral triangle

  30° - 12-pointed star

  0° - straight line

The two 12-pointed figures are shown in the attachment.

__

We suspect the star you're interested in is the one with points that are 30°. In order to have that point angle, the spider must make a turn of 180° -30° = 150°.

The spider will make 12 turns of 150°, for a total of 1800°, for a total of 5 full turns of 360°.

Answer:

Move the spide by 100 units and then turn the spider by 150 degrees. Repeat until you complete the star.

Answer:

x  = 7.45 inch for the maximum volume.

The area of the square = x² = 7.45² = 55.5025  inch²

Step-by-step explanation:

From the given information:

An open-top box is to be made from a 42-inch by 48-inch piece of plastic by removing a square from each corner of the plastic and folding up the flaps on each side.

The objective is to determine the length of the side x of the square cut out of each corner to get a box with the maximum volume

The volume of the box = l×b×h

The volume of the box = [tex](42 - 2x) \times (48-2x) \times (x)[/tex]

The volume of the box = [tex](2016 - 84x - 96x +4x^2)x[/tex]

The volume of the box = [tex](2016 -180x+4x^2)x[/tex]

The volume of the box = [tex](2016x -180x^2+4x^3)[/tex]

The volume of the box = [tex]4x^3 - 180x^2 +2016x[/tex]

For the maximum volume V' = 0

V' = [tex]12x^2 - 360x + 2016[/tex]

Using the quadratic formula; we have:

[tex]= \dfrac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]

where;

a = 12 , b = -360 c = 2016

[tex]= \dfrac{-(-360) \pm \sqrt{(-360)^2 -4(12)(2016)}}{2(12)}[/tex]

[tex]= \dfrac{360 \pm \sqrt{129600 -96768}}{24}[/tex]

[tex]= \dfrac{360 \pm \sqrt{32832}}{24}[/tex]

[tex]= \dfrac{360 \pm 181.196}{24}[/tex]

[tex]= \dfrac{360 + 181.196}{24} \ \ \ OR \ \ \ \dfrac{360 - 181.196}{24}[/tex]

[tex]= \dfrac{541.196}{24} \ \ \ OR \ \ \ \dfrac{178.804}{24}[/tex]

[tex]= 22.55 \ \ \ OR \ \ \ 7.45[/tex]

For the maximum value , we check the points in the second derivative term

V'' = 24x - 360

V'' ( 22.55) = 24(22.55) - 360

V'' ( 22.55) = 541.2 - 360  

V'' ( 22.55) = 181.2   (minimum)

V'' ( 7.45) = 24(7.45) - 360

V'' ( 7.45) = 178.8 - 360  

V'' ( 7.45) = -181.2  < 0  (maximum)

Therefore, x  = 7.45 inch for the maximum volume.

The area of the square = x² = 7.45² = 55.5025  inch²

The maximum volume of a box is the highest volume the box can take.

The side length that ensures maximum volume is 22.55 inches or 7.45 inches.

The dimension of the plastic is:

[tex]\mathbf{Length = 42}[/tex]

[tex]\mathbf{Width = 48}[/tex]

Assume the side length cut-out is x

So, the dimension of the box is:

[tex]\mathbf{Length = 42 - 2x}[/tex]

[tex]\mathbf{Width = 48 - 2x}[/tex]

[tex]\mathbf{Height = x}[/tex]

So, the volume of the box is:

[tex]\mathbf{Volume = Length \times Width \times Height}[/tex]

This gives;

[tex]\mathbf{Volume = (42 - 2x) \times (48 - 2x) \times x}[/tex]

Expand

[tex]\mathbf{Volume = (42 - 2x) \times (48x - 2x^2)}[/tex]

Expand

[tex]\mathbf{Volume = 2016x - 96x^2 - 84x^2 + 4x^3}[/tex]

Differentiate

[tex]\mathbf{V' = 2016 - 192x - 168x + 12x^2}[/tex]

[tex]\mathbf{V' = 2016 -360x + 12x^2}[/tex]

Rewrite as:

[tex]\mathbf{V' = 12x^2 -360x + 2016}[/tex]

Set to 0

[tex]\mathbf{12x^2 -360x + 2016 = 0}[/tex]

Divide through by 12

[tex]\mathbf{x^2 -30x + 168 = 0}[/tex]

Using a calculator, the values of x are:

[tex]\mathbf{x = 22.55\ or\ x = 7.45}[/tex] ------ approximated to 2 decimal places

Hence, the side length that ensures maximum volume is 22.55 inches or 7.45 inches.

Answer:

See below.

Step-by-step explanation:

The domain of a function is simply the span of x-values the graph will encompass.

And the range of a function is simply the span of y-values the graph will encompass.

Since the function is a quadratic, the domain is all real numbers. From the graph, the graph will continue to expand left and right. Therefore, the domain is all real numbers.

In interval notation, this is:

[tex](-\infty,\infty)[/tex]

And in set notation, this is:

[tex]\{x|x\in\mathbb{R}\}[/tex]

For the range, notice that the graph is going downwards. In other words, the graph has a maximum value. From the graph, we can see that this maximum value is at y=-4. The graph never reaches any value above -4. Therefore, our range is all numbers equal to or less than -4.

In interval notation, this is:

[tex](-\infty,-4][/tex]

We use brackets because we include the -4 in the solution set.

Also, note that we write the infinity first because the smallest number should be on the left. [-4, -∞) would not be correct.

And in set notation, this is:

[tex]\{y|y\in\mathbb{R},y\leq 4}\}[/tex]

================================================

Explanation:

The arc measures of 60 and x average to the angle 70, which is the the angle formed between the intersecting chords

70 = (60+x)/2

70*2 = 60+x

140 = x+60

x+60 = 140

x = 140-60

x = 80

The full 360 degree circle has the arc measures of 60, 79, x = 80, and w, where we don't know w yet. But we can add the four pieces of the circle to get 360

60+79+x+w = 360

60+79+80+w = 360

w+219 = 360

w = 360-219

w = 141

---------------

Or you could find angle z first

z+70 = 180

z = 180-70

z = 110

Then use the averaging technique done at the start of this problem

z = (79+w)/2

110 = (79+w)/2

2*110 = w+79

220 = w+79

w+79 = 220

w = 220-79

w = 141
