Answer:Sam's speed is about 10.3 mi/h.

Step-by-step explanation:Explanation:

Use dimensional analysis.

Determine the equality between miles and feet, and hours and minutes.

1 mi=5280 ft

1 h=60 m

Each equality can make two conversion factors, which are equal to one.

Step-by-step explanation: 184/4= 46

Answer:

200 > 100

Step-by-step explanation:

154 rounded to the nearest hundred is 200 because 154 is closer to 200 than to 100. and 145 is closer to 100 than it is to 200 so we have 200 and 100 and we know that 200 is greater than 100 so we can conclude with 200 > 100

650x0.1=65

the answer is 65 dollars uwu

Answer:

$65

Step-by-step explanation:

10% of 650 is 65 because you multiply .1 and 650, or move the decimal one place to the left. because the question asks for the discount price, you would just find the discount.

Answer:

[tex]\bold{y=1.5\times 2^x+4}[/tex]

Step-by-step explanation:

Given:

Exponential function with common ratio 2.

Horizontal asymptote at y = 4

Passes through point (2, 10)

To find:

Equation of the exponential function ?

Solution:

Equation for an exponential function may be given as:

[tex]y=ab^x+c[/tex]

Where b is the common ratio and

c is the y value of horizontal asymptote.

[tex](x, y)[/tex] are the points on the function.

We are given that:

b = 2

c = 4

Let us put all the given values and find equation.

[tex]y=a\times 2^x+4[/tex]

Now, let us put [tex]x = 2, y = 10[/tex] to find the value of a.

[tex]10=a\times 2^2+4\\\Rightarrow a\times 2^2=10-4\\\Rightarrow a\times 4=6\\\Rightarrow a =1.5[/tex]

[tex]\therefore[/tex] the equation of exponential function is:

[tex]\bold{y=1.5\times 2^x+4}[/tex]

Answer:

[tex] \boxed{ \boxed{ \bold{ \sf{d = 15}}}}[/tex]

Step-by-step explanation:

[tex] \sf{d - 7 = 8}[/tex]

Move constant to right hand side and change it's sign

⇒[tex] \sf{d = 8 + 7}[/tex]

Add the numbers

⇒[tex] \sf{d = 15}[/tex]

Let's check:

When d = 15 , R.H.S = 15 - 7 = 8

And L.H.S = 8

Thus , R.H.S = L.H.S when d = 15.

Therefore d = 15 is the solution of the equation.

Hope I helped!

Answer:12

Step-by-step explanation:

Answer:

(-10,8)

Step-by-step explanation:

So our original point is (-6,9).

A translation of 4 units to the left means that the x-value would go left by 4. In other words, we subtract 4 to -6. We subtract because going to the left means that it's going to the negative direction.

A translation of down 1 unit means that the y-value would go down by 1. In other words, we subtract 1. Again, we subtract because going downwards means that it's going to the negative direction.

Therefore, the new point would be:

[tex](-6-4,9-1)\\=(-10,8)[/tex]

Answer:

(-10,8)

Step-by-step explanation:

Step-by-step explanation:

Hey, there!!

Here,

3(2x-5)=25 is given.

To slolve: x

Now,

Multiply (2x-5) by 3.

6x-15 = 27.

Shift (-15) on right side.

6x= 27+15

or, 6x= 42

Divide 42 by 6.

[tex]x = \frac{42}{6} [/tex]

Therefore, x= 7.

Use FOIL

2•4+2(3i)+5i•4+5i(3i)

Simplify by combining like terms for your answer

8+6i+20i-15

-7+26i

Answer:

Step-by-step explanation:

7). Since the points J, K and L are on a same line, these points are collinear.

8). Point M is a point which is on the same plane with the points J, K and L but it is not collinear as the points J, K, and L are.

9). Points J, K, L and M are on the same plane (horizontal plane) but point N is not coplanar with these points.

10). Since a plane is named using 3 points lying on it. Therefore, JKL is the appropriate name of the given plane with these points.

Answer:

JKL is the appropriate name of the given plane with these points.

Answer:

98.02

Step-by-step explanation:

Take 26 and multiply by 277%

26 * 277%

Change to decimal form

26 * 2.77

72.02

That is the amount of the increase

Now add it to the original amount

26+72.02

98.02

Answer:

98.02

Step-by-step explanation:

[tex]26 + 26 \times \frac{277}{100} \\ = 26 + 26 \times 2.77 \\ = 26 + 72.02 \\ = 98.02[/tex]

Answer:

The sale this month = 79

Step-by-step explanation:

Let the amount he needs to sell this month = x

[tex]Average = \frac{sum\ of\ individual\ data\ }{number\ of\ entries}[/tex]

[tex]Average= \frac{90\ +\ 45\ +\ 103\ +\ 68\ +\ x}{5}[/tex]

Note that number of entries = number of months = 5

To maintain an average sales of 77, the amount of sale in month 5 is determined as follows:

[tex]77 = \frac{306\ +\ x}{5} \\cross-multiplying\\77\ \times\ 5\ = 306\ +\ x\\385 = 306\ +\ x\\x =385\ -\ 306\\x = 79[/tex]

Answer:

y = 9/5

4th Option

Step-by-step explanation:

Step 1: Write out function f(y)

f(y) = 5y - 3

Step 2: Define variable from problem

f(y) = 6

Step 3: Replace variable

6 = 5y - 3

Step 4: Add 3 to both sides

9 = 5y

Step 5: Isolate y by dividing both sides by 5

y = 9/5

Answer:

n = -6

Step-by-step explanation:

10[6(n+1)+5(n-1)]=13[7(5+n)-(25-3)]

You will collect like terms

10(6n+6+5n-5)=13(35+7n-25+3)

it will give you this

10(11n+1)=13(10+10n)

Then you remove the parenthesis

110n+10 = 130 +130n

Move the terms

110n -130n = 130-10

collect like terms

-20n=120

divide both sides

n=-6

Answer:

13.2

Step-by-step explanation:

Given

[tex]10x = 132[/tex]

Required

Determine the initial quantity

The interpretation of this question is to solve for the value of x

To start with:

[tex]10x = 132[/tex]

Divide both sides by 10

[tex]\frac{10x}{10} = \frac{132}{10}[/tex]

[tex]x = \frac{132}{10}[/tex]

[tex]x = 13.2[/tex]

Hence, the initial quantity is 13.2

Answer:

[tex]\huge\boxed{D, x -4}[/tex]

---- Starting with: ----

x² - 10x + 24

Since we have a leading coefficient of 1, simply find two numbers that sum up to -10 and multiply into 24.

By guessing and checking, we get the numbers -6 and -4. Put these into factors:

(x - 6)(x - 4)

Therefore, a binomial present in factored form is D. x - 4

Answer:

B

Step-by-step explanation:

Let first number = x

Second number = y

Twice a number = 2*x = 2x

The sum of twice a number and another number is 24

2x + y  = 24    -----------------------(I)

The difference of twice the first number and the  other number is 12.

2x - y = 12 ----------------------(II)

Add equation (I) & (II)  and y will be eliminated and we can find the number 'x'

(I)       2x + y = 24

(II)      2x - y  = 12   {Now add the two equations}

          4x      = 36

Divide both sides by 4

4x/4 = 36/4

x = 9

Plug in the value of 'x' in equation (I)

2*9 + y = 24

 18 + y = 24

Subtract 18 from both sides

18 + y - 18 = 24 - 18

       y = 6

The numbers are 9, 6

Answer:

A. Width = 25   Length = 15

Step-by-step explanation:

Length = L = Width - 10

Width = W

Perimeter of a rectangle

=> 2 (L + B) = 80

=> 2 (W - 10 + W) = 80

=> 2 (2W - 10) = 80

=> 4W -20 = 80

=> 4W -20 + 20 = 80 + 20

=> 4W = 100

=> 4W/4 = 100/4

=> W = 25

Width = 25

Length = 25 - 10 = 15

So, the answer is A.

Answer: $184,080

Step-by-step explanation:

First multiply 18% by the original budget to find how much the 18% of the budget was .

18% * 156,000  = 28080

Now add  add 28080 to the original budget to find out how much she actually spent.

156,000 + 20,080 = 184,080

5(0.3) + 2y = 20

| 5(0.3) + 2y = 20

| Multiply 5 and 0.3 to get 1.5

\/

1.5 + 2y = 20

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

We subtract 1.5 from both sides.

2y = 20 - 1.5

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Subtract 1.5 from 20 to get 18.5.

2y = 18.5

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Divide both sides by 2.

[tex]y = \frac{18.5}{2}[/tex]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Expand [tex]\frac{18.5}{2}[/tex] = 9.25 by multiplying both numerator and the denominator by 10.

[tex]y =\frac{185}{20}[/tex]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Reduce the fraction [tex]\frac{185}{20} = 9.25[/tex] to lowest terms by extracting and canceling out 5.

[tex]y =\frac{37}{4}[/tex].

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[tex]\frac{37}{4} = 9.25[/tex] in decimal form.

Answer:

c = -12

Step-by-step explanation:

Quadratic Standard Form: ax² + bx + c

Step 1: Write equation

3x² + 6x = 12

3x² + 6x - 12 = 0

Here, we have the standard form of the quadratic. We see that our c = -12

Answer:

[tex]\huge \boxed{{10x^2 + 12x \mathrm{\ units^2 }} }[/tex]

Step-by-step explanation:

area of shaded region = area of whole rectangle - area of unshaded region

Area of a rectangle is length × width.

A = 5x(3x+2) - (x(5x-2))

Expand brackets.

A = 15x² + 10x -(5x² - 2x)

Distribute negative sign.

A = 15x² + 10x - 5x² + 2x

Combine like terms.

A = 10x² + 12x

Answer:

418.2477796 m

Step-by-step explanation:

You divide it in to a rectangle and 2 half circles (which will make a whole circle if added together) and solve them.

P= 2( L + W) - - > 2 ( 102 + 60)= 324

Cf= 2лr^2 - - - > 2л(30)^2=30л

324 + 30л = 418.2477796 m
