Answer:

Step-by-step explanation:

12s=1152 (divide each side by 12 to isolate s)

s=96

So there were 96 students.

Question

A pair of Sneakers cost $112 after it was marked up by 75%. How much

did it cost before the mark-up?

Answer

Divide the gross profit by the cost and multiply by 100 to calculate your percentage markup. In the example, divide $75 by $100 which equals $0.75, and multiply by 100 to give you 75 percent. Your markup on cost price is 75 percent.

Therefore, the answer would be (196)

Answer:

i believe the answer would be $448

Step-by-step explanation:

hopefully this helps :)

have a nice day !!

**please let me know if this was wrong**

Answer:

True

Step-by-step explanation:

It is true because the graph of [tex]y=x-12[/tex] passes through the point [tex](16,4)[/tex]

x = 16

y = 4

Substitute

4 = 16 - 12

4 = 4

Therefore, the answer is true.

Answer:

16.6 for nearest tenths

16.57 for nearest hundreths

Step-by-step explanation:

4/7*29/1=

29*7=203/7 to get the same denominator

203 x  4  = 812    mulptiply to get the fraction

 7    x   7 =  49

812/49=16.5714285714

Answer:

Step-by-step explanation:

A=bh/2

A=(1.2b)(1.2h)/2

A=1.44(bh)/2

A=0.72bh

b=10cm and h=5c

A=0.72(10)(5)

A=36 cm^2

Answer:

36cm sqaured

Step-by-step explanation:

Step-by-step explanation:

A=bh/2

A=(1.2b)(1.2h)/2

A=1.44(bh)/2

A=0.72bh

b=10cm and h=5c

A=0.72(10)(5)

A=36 cm^2

Answer: Distributive Property

Explanation: The distributive property tells us that if we're given an expression such as -3(m + 8), we can multiply the -3 by both the m and the 8.

Answer:

Step-by-step explanation:

F=ma

F=m(dv/dt)

F=1400(-36/4)

F=-12600N (the negative sign just means the force was slowing the vehicle, the magnitude of the force is just the absolute value.

F=12600N

Answer:

I think the answer would be y<4

Step-by-step explanation:

▪AB = AC - EF

= 13 cm - 7 cm

= 6 cm

▪BD = CF - DE

= 16 - 8 cm

= 8 cm

BC = EF

perimeter = CF + EF + DE + AD + AB + BC

= 16 + 7 + 8 + 10 + 6 + 7

= 54 cm

Area of triangles = 1/2 × AB × BD

= 1/2 × 6 × 8

= 48/2

= 24 cm²

Area of rectangle = CF × EF

= 16 × 7

= 112 cm²

the total area = 24 + 112

= 136 cm²

Answer:

Step-by-step explanation:

70+11.5x>440 subtract 70 from each side

11.5x>370 divide each side by 11.5

x>32.17 to nearest tenth

x>32.2

Answer:

9 = x (assuming 15 is the hypotenuse)

Step-by-step explanation:

15^2 = 12^2 + x^2

225 = 144 + x^2

subtract 144 from both sides

81 = x^2

square root both sides

9 = x

Answer:

x = -35/22, or 1.5909090...

Step-by-step explanation:

Solving for x will be easy enough, but cross multiplication won't be necessary as that's only applicable when division is involved:

35 = 2x - 24x

35 = -22x

x = -35/22, or 1.5909090...

Answer:

These types of numbers are commonly referred to as "irrational numbers".

Step-by-step explanation:

Answer:

22 + 5y

Step-by-step explanation:

Yes they are

5 x 2 = 10 + 5 x y = 5y, 10 + 12 = 22, therefore you get 22 + 5y.

Answer:

441 π ft²

Step-by-step explanation:

If you mean volume, this is how it is:

v = πr² × h = π × 7² × 9 = 441π ≈ 1323 ft²

Answer:

45

Step-by-step explanation:

hello there!

Remember all of the angles in a triangle will add up to equal 180 so to find the missing angle we subtract the given angles from 180

180 - 90 - 45 = 45 so the missing angle would equal 45

Answer:

[tex]z = -0.8[/tex]

Step-by-step explanation:

Given

[tex]n = 32[/tex] --- samples

[tex]\mu = 18g[/tex] --- mean

[tex]\sigma =5g[/tex] --- standard deviation

[tex]x = 14g[/tex] --- observed value

Required

Find the standardized score

This is calculated as:

[tex]z = \frac{x - \mu}{\sigma}[/tex]

So:

[tex]z = \frac{14g -18g}{5g}[/tex]

[tex]z = \frac{-4g}{5g}[/tex]

[tex]z = \frac{-4}{5}[/tex]

[tex]z = -0.8[/tex]

The standardized score is -0.8

Answer:

-5 degrees! If you did 20-25 it would get you -5! Hope this helps :)

Step-by-step explanation:

Answer:

1456

Step-by-step explanation:

This question is asking us to find the sum of [tex]4(3)^{n-1}[/tex] from n = 1 to n = 6. We can find the sum like this:

[tex]4(3)^{1-1} +4(3)^{2-1} +4(3)^{3-1} +4(3)^{4-1} +4(3)^{5-1} +4(3)^{6-1}[/tex]

Which can be simplified to:

[tex]4(3)^{0} +4(3)^{1} +4(3)^{2} +4(3)^{3} +4(3)^{4} +4(3)^{5}[/tex]

[tex]4(1) +4(3) +4(9) +4(27)+4(81) +4(243)[/tex]

[tex]4 +12 +36 +108+324 +972 = 1456[/tex]

Answer:

x = -4

Step-by-step explanation:

x= 3 is a parallel to y axis. So a parallel line to x = 3 must be parallel to y axis.

A line parallel to y axis has a generic equation: x = h. We know that the line passes to the point with has x coordinate = -4

So the equation is x= -4

Answer:

x= 0
