Answer:

The area of the smaller triangle is 80m²

Step-by-step explanation:

Find the scale factor to get the dimensions of the smaller triangle from the larger triangle using the given information:

[tex]\frac{\text{Large Triangle Length}}{\text{Small Triangle Length}}=\frac{12}{8}=\frac{3}{2}[/tex]

When scaling the area of similar shapes, we will square the scale factor for the lengths. We do this because area is a 2-dimensional measurement.

[tex](\frac{3}{2})^2=\frac{9}{4}[/tex]

Let x represent the area of the smaller triangle. So, we have:

[tex]\frac{9}{4}=\frac{180}{x}[/tex]

Cross multiply:

[tex]9x=4(180)[/tex]

[tex]9x=270[/tex]

Divide by 9:

[tex]x=\frac{720}{9}[/tex]

[tex]x=80[/tex]

Therefore, the area of the smaller triangle is [tex]80m^2[/tex].

Step-by-step explanation:

Domain is all possible values that can be used as inputs in a function.

The arcade machine accepts multiples of 5 game tokens. You have 20 tokens. As the machine accepts 5 game tokens, the minimum is 5. Since you have 20, the maximum is 20.

The multiples of 5 are:

5 x 1 = 5

5 x 2 = 10

5 x 3 = 15

5 x 4 = 20

Answer: 0.94

Step-by-step explanation:

The required probability of getting at least one tail is given as 0.94. Option D is correct.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
The probability of getting tails at least one time is given as,
P(T) = 1 - P(T)'

From the given table.
P(T) = 1 - 0.06

P(T) = 0.94

Thus, the required probability of getting at least one tail is given as 0.94. Option D is correct.

The figure contains a triangle and a semicircle

The area of the figure is 49.12 square feet

The dimension of the triangle is:

Base = 8 ft

Height = 6ft

So, the area is:

Area = 0.5 * Base * Height

This gives

Area = 0.5 * 8ft * 6ft

Evaluate

Area = 24 square feet

The radius of the semicircle is:

r = 4 ft.

So, the area is:

[tex]Area = 0.5\pi r^2[/tex]

This gives:

Area = 0.5*3.14 * 4^2

Area = 25.12 square feet

Add the calculated  areas.

Total = 24 square feet + 25.12 square feet

Total = 49.12 square feet

Hence, the area of the figure is 49.12 square feet

Answer:

The car will be worth £2516.22 in 5 years

Step-by-step explanation:

The rule of depreciating is  

[tex]A=P(1-r)^{t}[/tex], where

∵ Dan buys a car for £2700

∴ P = 2700

∵ It depreciates at a rate of 1.4% per year

∴ r = 1.4% = 1.4/100 = 0.014

∵ We need to find how much it will be worth in 5 years

∴ t = 5

→ Substitute all of these values in the rule above to find A

∵ [tex]A=2700(1-0.014)^{5}[/tex]

→ Use your calculator to find the answer

∴ A = 2516.22

∴ The car will be worth £2516.22 in 5 years

Answer:

A = 12.554 square inches

Step-by-step explanation:

Let's start with the formulas:  

Circumference = [tex]2\pi r[/tex]; Area = [tex]\pi r^{2}[/tex]

We can use the circumference to find the radius, r, which we need for the area

12.56 = [tex]2\pi r[/tex]

Isolating r gives us [tex]\frac{12.56}{2\pi } = r[/tex]

A = [tex]\pi (\frac{12.56}{2\pi })^{2}[/tex]

Solving gives us 12.554, which you can further round if necessary.

We multiply those 57.5 calories with 6 ounces

57.5(6) = 345, there are 345 calories in 6 ounces.

(note that you formatted the question wrong, it was supposed to be):

There are 230 calories in 4 ounces of a type of ice cream, how many calories are in 6 ounces of that ice cream?

We know that:

[tex]1. \space\ r + s + t = 180 + 180 + 180 - (Sum \space\ of \space\ interior \space\ angles \space\ of \space\ a \space\ triangle)\\ \\ 2. \space\ Sum \space\ of \space\ interior \space\ angles \space\ of \space\ a \space\ triangle = 180[/tex]

This means that:

[tex]1. \space\ r + s + t = 180 + 180 + 180 - (180)[/tex]

Let's simplify the equation to find r + s + t.

Simplifying the equation:

[tex]r + s + t = 180 + 180 + 180 - (180) \\ \\ r + s + t = 180 + 180 + 180 - 180 \\ \\ r + s + t = 180 + 180 \\ \\ r + s + t = 360[/tex]

Thus, the sum of r, s and t is 360°

Answer: the sum of r, s and t is 360°

Answer: y=-5x-1

Step-by-step explanation:

The two given points are (-1,4) and (1.-6)

We can then use the slope formula (Y2-Y1)/(X2-X1) to find the slope

4-(-6)/ -1-1 = 10/-2 = -5

Slope is -5

We then plug the slope in a set of points to find the y intercept

-5*-1+x = 4

5+x=4

x=-1

Then just add these two together to form the equation of y=mx+b

y=-5x-1

The pairs of legging purchased is 3

Let the number of leggings be x.

The cost per legging is given as:

$12

So, the total amount is:

Total = 12x

The flat rate is given as:

Flat rate = 5

So, we have:

Total = 12x + 5

Your total is $41

So, we have:

12x + 5 = 41

Subtract 5 from both sides

12x = 36

Divide through by 12

x = 3

Hence, the pairs of legging purchased is 3
