3x=24

x= 8

So the angle 7(8)-9 = 47°

Answer 2

Answer:

m<ABC=<7x-9=7×8-9=47° is your answer

Step-by-step explanation:

4x+15=7x-9 vertically opposite angle

Add all numbers from Mon-Fri.

So 985.

Multiply it by 0.78

So $768.30

Add 0.78 and 0.38

So 1.16

Then multiply 90 by 1.16

So $104.40

Then add the two numbers.

768.30+104.40

So $872.70

Work out the area of the trapezium ABDE.
A
В.
7.5 cm
2.5 cm
С
5 cm
E

Answers

Answer:

Area = 50 cm²

Step-by-step explanation:

Area of a trapezium ABDE = ½(a + b)h

where,

a = BD = 2.5 cm

b = AE = 7.5 cm

h = DE = ?

We need to find DE ti be able to calculate the area.

DE = CE - CD

DE = CE - 5

Since ∆ACE is similar to ∆BCD, therefore:

AE/BD = CE/CD

Plug in the values

7.5/2.5 = CE/5

Cross multiply

CE*2.5 = 7.5*5

CE*2.5 = 37.5

Divide both side any 2.5

CE = 37.5/2.5

CE = 15

Thus, DE = CE - 5 = 15 - 5

DE = 10

✅Area of trapezium = ½(BD + AE)DE

= ½(2.5 + 7.5)*10

= ½(10)10

= 50 cm²

The average person's stride lenghth the distance covered by one step is aproximently 2.5 feet long. How many steps would the average person take to travel 50 feet?

Answers

Answer: 20 steps

Step-by-step explanation:

From the question, we are informed that the average person's stride length the distance covered by one step is 2.5 feet long.

To know the steps that the average person would take to travel 50 feet, we simply have to divide 50 feet by 2.5 feet. This will be:

= 50 / 2.5

= 20

This means that an individual will take 20 steps to travel 50 feet

_________________

X = (-1, 2).

Y = (2, -1).

Z = (-2, -1).

_________

Dₙ ∆XYZ:

X(-1, 2) → X'(-2, 4)

Y(2, -1) → Y'(4, -2)

Z(-2, -1) → Z'(-4, -2)

______________

-2 / -1 = 2, 4 / 2 = 2.

4 / 2 = 2, -2 / -1 = 2.

-4 / -2 = 2, -2 / -1 = 2.

_______________

D₂ = (x,y) → ((2)x, (2)y).

X(-1, 2) → ((2)(-1), (2)(2)) = X'(-2, 4)

Y(2, -1) → ((2)(2), (2)(-1)) = Y'(4, -2)

Z(-2, -1) → ((2)(-2), (2)(-1)) = Z'(-4, -2)

The graphs below were created by an advertising agency for the computer store TechPlus to show its average price on laptops and desktops compared to another computer store's prices.

Which of the following statements best explains how the advertising agency misrepresented the data?

The graphs use different scales, making it appear that the prices at TechPlus are much lower than CompStar.

The graphs were created with different colors.

The graph for CompStar makes its prices appear much higher, but its prices are only a little higher.

The graphs do not include tablet computers, so there is not enough information to compare their prices.

Answers

The misrepresentation lies in the fact that ; The graphs use different scales, making it appear that the prices at TechPlus are much lower than CompStar.

Taking a look at both graphs, it could be observed on the y - axis that the graphs do not follow the same scale.

For CompStar, the y-axis which shows the price of laptops and desktops starts it's labeling from $0 ; while TechPlus's labeling began from $600

This representation means that comparing the two graphs would give an erroneous inference as it would make the price of TechPlus appear lower than that of Complus.
