find the distance for d

Answer:

They had 1,352 marbles all together, rounded to the nearest hundred, 1,400.

Step-by-step explanation:

All we have to do is add the number of marbles they collected.

510 + 842 = 1,352

1,352 rounded to the nearest hundred is 1,400.

Answer: $54.35

Step-by-step explanation:

If each one of the 15 students raises the same amount, let's define this amount by the variable X, then the total amount they will collect is 15 times X, or:

15*X

And the minimum amount they need to collect is $800

Then we will have the inequality:

15*X ≥ $800

Now we can divide both sides by 15 to get the minimum amount that each student needs to raise:

(15*X)/15 ≥ $800/15

X ≥ $54.33...

Where we should round up the right number to $54.35, because we can not have a $0.0333... and if we round down, they would collect less than $800.

Then the inequality is:

X ≥ $54.35

This means that the minimum amount that each one of the 15 students needs to collect is $54.35

In multiplication, the exponents add up.

5.5²=5¹.5²=5³

Note:

In the extraction ,the exponents remove.

5¹⁰÷5³=5⁷

Answer:

5³

Step-by-step explanation:

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]

Given

5 × 5²

= [tex]5^{1}[/tex] × 5²

= [tex]5^{(1+2)}[/tex]

= 5³ ← in index form

= [ 125 ]

Answer: [tex]2.78m^{2}[/tex]

Step-by-step explanation:

given data:

height of the statue = 80m.

base of the statue = [tex]625m^{2}[/tex].

scale of the statue replica = 1:15.

solution:

[tex]= 1:15^{2} \\\\\= 1:225\\\\[/tex]

[tex]= \frac{625m^{2} }{225}[/tex]

= [tex]2.78m^{2}[/tex]

the area of the replica is [tex]2.78m^{2}[/tex]

Answer:

2.78 m^2 is the correct answer. :)

Answer: 25%

Step-by-step explanation:

Given: A rectangle has length 4 inches and width 2 inches.

Area = Length x width

= 4 inches x  2 inches

= 8 square inches

If length is reduced by 50% , then length [tex]=0.5\times4=2\text{ inches}[/tex]

If width is reduced by 50% , then length [tex]=0.5\times2=1\text{ inch}[/tex]

Reduced area = (reduced length) x (reduced width)

= 2 inches x 1 inch

= 2 square inches

The percentage of the area of the rectangle be reduced :-

[tex]\dfrac{\text{Reduced area}}{\text{Original area}}\times100 \\\\=\dfrac{2}{8}\times100\% \\\\=25\%[/tex]

Hence, the percent of the area of the rectangle be reduced = 25%

Answer: 18 and 37

Answer:

1

Step-by-step explanation:

Subtract the two numbers and take the positive value  ( since distance is positive)

-8/5 - (-3/5)

-8/5 + 3/5

-5/5

-1

Taking the positive value, 1

Answer:

b) 18

Step-by-step explanation:

600 - 150 = 450

25x = 450

x = 18

check

25 x 18 = 450

450 + 150 = 600

Step-by-step explanation:

The polar form of z is 6√2(cos(135°) + isin(135°)).

Complex numbers are represented in polar form as the complex number's modulus r and argument combined. Given as  z = r cosθ + i r sinθ = r (cosθ + i sinθ).  the polar form of the complex number z = x + iy with coordinates (x, y) is given. Polar coordinates of real and imaginary numbers in the coordinate system are used to express the polar form. A complex number in a two-dimensional coordinate system is  A = x + i y

Given the point z

From the positive real axis, the angle to the point in the second quadrant is calculated (the x-axis). The only options that make sense for the second quadrant are the 135° angles, which fall between 90° and 180°.

The square root of the sum of the squares of z's components determines its magnitude:

|z| = [tex]\sqrt{x^{2} + y^{2} }[/tex]

here x = -6 and y = 6

|z| = √(-6²) + (6²)

z = 6√2

polar form is

z = 6√2(cos(135°) + isin(135°))

Hence the complex form is 6√2(cos(135°) + isin(135°)).

Answer:

2 1/3 ; 9 1/3

Step-by-step explanation:

Given that:

Outside temperature increases by 3 1/2 degrees every 1 1/2 hours

The rate per hour of temperature increase will be :

Let rate per hour = x

3 1/2 = 1 1/2

x = 1

Cross multiply :

1 1/2 * x = 3 1/2 * 1

3x/2= 7/2

Multiply both sides by 2/3

3x/2 * 2/3 = 7/2 * 2/3

x = 14/ 6

x = 2 2/6

x = 2 1/3

Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.

2.) Temperature increase after 4 hours :

(Temperature rate per hour * number of hours)

(2 1/3) * 4

(7/3) * 4

28 / 3

= 9 1/3

Hence, temperature increase after 4 hours = 9 1/3

2 1/3 ; 9 1/3

Step-by-step explanation:

Given that:

Outside temperature increases by 3 1/2 degrees every 1 1/2 hours

The rate per hour of temperature increase will be :

Let rate per hour = x

3 1/2 = 1 1/2

x = 1

Cross multiply :

1 1/2 * x = 3 1/2 * 1

3x/2= 7/2

Multiply both sides by 2/3

3x/2 * 2/3 = 7/2 * 2/3

x = 14/ 6

x = 2 2/6

x = 2 1/3

Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.

2.) Temperature increase after 4 hours :

(Temperature rate per hour * number of hours)

(2 1/3) * 4

(7/3) * 4

28 / 3

= 9 1/3

Hence, temperature increase after 4 hours = 9 1/3

Answer:

Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Todhunter (1888) who wrote it as "y = mx + c".
