Which expression is equivalent to the given expression?

Answer:

-0.2588 but rounded is -0.26

Step-by-step explanation:

Answer:

∠ QRS = 132°

Step-by-step explanation:

Since the triangle is isosceles then the 2 base angles are congruent, that is

∠ PQR = ∠ PRQ = [tex]\frac{180-84}{2}[/tex] = [tex]\frac{96}{2}[/tex] = 48°

∠ PRQ and ∠ QRS are adjacent angles , so

∠ QRS = 180° - 48° = 132°

Step-by-step explanation:

This is a right triangle with two congruent angles. so this is a isoceles right triangle or called a

45-45-90 triangle. This means that the legs are equal to each other so

[tex]3(x + 2) = 24[/tex]

[tex]3x + 6 = 24[/tex]

[tex]3x = 18[/tex]

[tex]x = 6[/tex]

Answer:

8.1, 41/5, 8.2 repeating, √76

Step-by-step explanation:

Answer:

8.1 < 41/5 < 8.2 < √76

Step-by-step explanation:

41/5 = 8 1/5 = 8.20

   _

8.2 = 8.222 ...

√76 ≈ 8.7

8.1                                                                  _

8.1 < 8.20 < 8.222 ... < 8.7 = 8.1 < 41/5 < 8.2 < √76

Answer:

63. Perimeter: 60.4 units

Area: 126.14 units²

64. x = 8

m = 62⁰

Step-by-step explanation:

First, let us solve question 63. To find the perimeter and the area of the triangle, we will first find the x and y value.

Formulas we would use to find the answer in Q. 63 :-

Cos = opposite / hypotenuse

Sin = adjacent / hypotenuse

Area = 1/2 × b × h

Perimeter = adding all sides

Let us find the y value using the formula of Cos.

Cos = opposite / hypotenuse

Cos24⁰ = y / 26

26(Cos24⁰) = (y / 26)26

26(Cos24⁰) = y

23.8 = y ---> *since it said to round to the nearest hundredth.*

Now let us find the x value by using the formula of Sin.

Sin = adjacent / hypotenuse

Sin24⁰ = x / 26

26(Sin24⁰) = (x / 26)26

26(Sin24⁰) = x

10.6 = x ---> *since it said to round to the nearest hundredth.*

Now let us find the perimeter and the area.

Area = 1/2 × b × h

Area = 1/2 × 10.6 × 23.8

Area = 126.14 units²

Perimeter = adding all sides.

Perimeter = 26 + 23.8 + 10.6

Perimeter = 60.4 units

On to Q. 64. Formulas we would use to find the answer of Q. 64 is :-

Tan = opposite / adjacent

Sin = opposite / hypotenuse

Let us find m. In order to find m, we will use the Sin formula.

Sin = opposite / hypotenuse

Sinm⁰ = 15 / 17

m⁰ = sin-1(15 / 17)

m⁰ = 62 ---> *since it said to round to the nearest whole number.*

Now let us find x by using the formula of Tan.

Tan = opposite / adjacent

Tan62⁰ = 15 / x

x(Tan62⁰) = (15 / x)x

x(Tan62⁰) = 15

x(Tan62⁰) / Tan62⁰ = 15 / Tan62⁰

x = 15 / Tan62⁰

x = 8 ---> *since it said to round to the nearest whole number.*

Hope this helps, thank you :) !!

D. 45,000 ft,²

As per the scale given,

1 in. = 15 ft.

10 in. = 10×15 ft. = 150 ft.

20 in. = 20×15 ft. = 300 ft.

So, area = 150 ft. × 300 ft. = 45,000 ft.²

Answer:

88 in

Step-by-step explanation:

find the area of each shape individually

triangles - 3x8=24 and you don't have to divide by 2 because there's 2 triangles.

rectangles - 8x4x2=64 you multiply by 2 because there are 2 rectangles.

then you add the rectangles and triangles together.

Answer:

88 (is the total area since I did not really get what you were asking)

Step-by-step explanation:

The question is basically asking to find the rectangle and triangle and then multiply both by 2.

Find the rectangle:

4 x 8 = 32

Find the triangle:

7 - 4 = 3

3 x 8/2 = 12

Multiply by 2:

32 x 2 = 64

12 x 2 = 24

Add the two up..

64 + 24 = 88

The speed of the car is 75 mph

===========================================================

Explanation:

The four given points on the diagonal line are:

Pick any two points from that list of four. I'll pick the first two points. The coordinates are then plugged into the slope formula below

m = (y2-y1)/(x2-x1)

m = (150-75)/(2-1)

m = 75/1

m = 75 so the answer is choice C

The rate of change of 75 means that each time x goes up by 1, y increases by 75.

For each hour that passes, the car has traveled 75 miles. Therefore, the rate of change is 75 miles per hour.

-----------

Note how,

In short, the slope represents the speed of the car. If the line remains the same slope, then the speed is constant.

Answer:

248

Step-by-step explanation:

Solution for What is 400 percent of 62:

400 percent *62 =

(400:100)*62 =

(400*62):100 =

24800:100 = 248

Now we have: 400 percent of 62 = 248

Question: What is 400 percent of 62?

Percentage solution with steps:

Step 1: Our output value is 62.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$62=100\%.

Step 4: Similarly, x=400\%.

Step 5: This results in a pair of simple equations:

62=100\%(1).

x=400\%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

\frac{62}{x}=\frac{100\%}{400\%}

Step 7: Again, the reciprocal of both sides gives

\frac{x}{62}=\frac{400}{100}

\Rightarrow x=248

Therefore, 400 of 62 is 248

Answer:

248

Step-by-step explanation:

[tex]\frac{y}{400}: \frac{62}{100}[/tex]

y · 100 = 62 · 400

100y = 24800

100y ÷ 100 = 24800 ÷ 100

y = 248
