Answer:

$300

Step-by-step explanation:

Given data

Mike saves 20% of every paycheck

Last paycheck= $1,500

Hence the amount saved

=20/100*1500

=0.2*1500

=$300

Hence he will save $300

Answer:

A general exponential equation is written as:

y = a*(b)^x

Where:

y represents the amount of something as a function of the variable x, where x is an independent variable.

a is the initial amount, this is, the value of y when x = 0.

b is the rate of growth, this defines how much changes the value of y as x increases.

Answer:

x1 = 2 and x2 =7/2 or 3.5 yeah it says I need 20 word but I'm done so bye good luck!

Answer:

The value of 'k' for the given system of equation that coincides  is 4

k=4

Given :

System of equations

[tex]2x+y=40 \\kx+2y=80[/tex]

The given equation is in the form of ax+by=c

When the two lines coincides then

[tex]\frac{a_1}{a_2} =\frac{b_1}{b_2} =\frac{c_1}{c_2}[/tex]

Lets make the coefficients proportional to each other and then solve for k

[tex]\frac{2}{k} =\frac{1}{2} =\frac{40}{80} \\\frac{2}{k} =\frac{1}{2} =\frac{1}{2} \\\\\frac{2}{k} =\frac{1}{2} \\4=k\\k=4[/tex]

The value of k from the given system of equation is 4

When the line coincides then the value of k is 4

Answer:

60°

Step-by-step explanation:

A triangle with two 60° angles has another 60° because 180-(60+60)=180-120=60°.

Also, this is an equilateral triangle.

Answer: a is the answer

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Simply guess and check, meaning the boys category must be divisible by 2 and the girls category must be divisible by 3

A: 24 boys ÷ 2 = 12 (equals a whole number so it is divisible; not a decimal)

36 girls ÷ 3 = 12 (both of the boys and girls are divisible by their corresponding numbers)

Yes

Now make sure the boys are a lower count than the girls as the ratio says it should be 2 to 3, meaning there are more girls than boys

B: 20 ÷ 2 = 10 (divisible)

35 ÷ 3 = 11.666 (this is a decimal answer so it is not divisible)

No

C: 36 ÷ 2 = 18

24 ÷ 3 = 8

Yes, they are divisible

Now lets check if boys have a lower count than girls

36 boys > 24 girls

This is not the solution as it doesn't reflect the correct ratio of less boys than girls

D: 35 ÷ 2 = 17.5 (not divisible)

20 ÷ 3 = 6.66 (not divisible)

Answer:

C

Step-by-step explanation:

Area = π[tex]r^{2}[/tex]

r means radius

radius = d/2

d = diameter

8 /2 = 4

4 is radius

[tex]4^{2}[/tex] = 16

^ ( its 4 x 4 ) ^

so then,

Area = 16π

Answer:

Step-by-step explanation:

[tex]A=\pi r^2,\ r=\frac{d}{2}\\ \\ A=\frac{\pi d^2}{4},\ d=8cm\\ \\ A=\frac{64\pi}{4}\\ \\ A=16\pi cm^2[/tex]

Answer:

6cm

The dimensions are 6cm x 6cm x 6cm

Step-by-step explanation:

Surface area of a cube = 6a²

where a = edge

but because this cube isn't covered, the sides would by 5 and not 6

5a² = 180cm²

divide both sides by 5

a² = 36cm²

Find the square root of each side

a = 6cm

The dimensions are 6cm x 6cm x 6cm

Answer:

x=5.9

Step-by-step explanation:

First, you want to isolate x so you have to subtract 31.7 from both sides. This will make the equation -3x=-17.7. Because they are both sides are negative, you can change both sides to positive so it will be 3x=17.7. Next, you want x to be 1 so you have to divide 3 in both sides. This will make the equation x=17.7/3. Simplify that to get x=5.9.
