Answer:

  h = 2m

Step-by-step explanation:

We can put the given values into the area formula and solve for the missing one.

  A = (1/2)(b1 +b2)h

  7m²= (1/2)(3m +4m)h

  7m² = (7/2)m·h

  (7m²)(2/(7m)) = h = 2m

The missing height is 2 m.

Answer:

D. 6 cups of oil to 12 cups of milk.

Answer:

1) 27.374

2)9.177

Step-by-step explanation:

1) To get the value of x , we use the appropriate trigonometric ratio

From what we are given;

we have the hypotenuse ( the side facing the right angle) and the adjacent

The trigonometric identity to use here is the cos

The cos of an angle is the ratio of the adjacent to the hypotenuse

cos 64 = 12/x

x = 12/cos 64

x = 27.374

2) Here, we are given the hypotenuse and the opposite

The trigonometric ratio to use here is the sine

the sine of an angle is the ratio of the opposite to the hypotenuse

thus, we have it that;

sin 35 = x/16

x = 16 sin 35

x = 9.177

Answer:

11=x

Step-by-step explanation:

since the lines are parallel the distances between each section of line is proportional to each other.

5/6=(x-1)/12

multiply both sides by 12

12(5/6)=(x-1)12/12

10=(x-1)

add 1 to both sides

10+1=x-1+1

11=x

Answer:

105.5%

Step-by-step explanation:

The percentage change can be calculated as follows

= 210.99/200

= 1.05495 × 100

= 105.5%

Hence the percentage change is 105.5%

Answer ad Step-by-step explanation:

1. Adding 10mn and -15mn.

10mn + -15mn = -5mn.

2. Adding [tex]-7a^{2}[/tex] and [tex]-8a^{2}[/tex].

[tex]-7a^{2} + -8a^{2} = -15a^{2}[/tex].

3. Adding 6(x + 3) and -7(x + 3).

6x + 18 + -7x - 21

x - 3.

4. Adding ?

5. Adding 0.5xyz and 1.5 xyz.

0.5xyz + 1.5xyz = 2xyz.

Answer:

Area of sector ≈ 15.6π (nearest tenth)

Step-by-step explanation:

Given:

radius = 5 cm

Central angle in radians = ∅ = 5π/4

Required:

Area of the sector

Solution:

Area of sector = ½*r²*∅

Plug in the values into the formula

Area of sector = ½*5²*5π/4

= ½*25*5π/4

= 12.5*5π/4

= (12.5*5π)/4

Area of sector = 15.625π ≈ 15.6π (nearest tenth)

Step-by-step explanation:

Given points

let ( x1, y1 ) = ( - 2 , 2) and (x2 , y2 ) = (7, 3)

slope of the line (m)

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

= ( 3 -2 ) / ( 7 + 2)

= 1 / 9

hope it helps :)

Answer:

Answer:

A = 173.82

Step-by-step explanation:

[tex]A = 2 (1 + \sqrt{2}) a^{2}[/tex]

a = 6

substitute 6 for a

A = 2 (1 + [tex]\sqrt{2}[/tex]) [tex]6^{2}[/tex]

solve:

A = 2 (1 + [tex]\sqrt{2}[/tex]) 36

A = 173.82

Answer:

Around 173.8 km (rounded to the nearest tenth of a km

Step-by-step explanation:

The area of an octagon can be found using the expression:

A=2(1+sqrt of 2)a^2

plug your side of 6 in to create the following equation:

A=2(1+sqrt of 2)(6^2)

Solve for A:

A= (2 + 2*sqrt of 2)(36) I multiplied 6 by 6 to get 36 and used distributive property on the other section.

A=72+72sqrt of 2

plug that in a calculator and you get around 173.8 km

Answer:

(7,2)

Step-by-step explanation:

Multiply the first equation by -3

(x-3y=1)  = -3x+9y=-3

Combine like terms with the new equation and the second equation

(-3x+9y=-3) + (3x-5y=11)   = 4y=8

Divide each side by 4

4y/4=8/4

y=2

Plug in 2 for y in any equation. It doesn’t matter which one

x-3(2)=1

Distribute

x-6=1

Add 6 to both sides

x-6=1

+6  +6

x=7

Answer: x = 7 y = 2

(7, 2)

Step-by-step explanation:

Multiply the first equation by -3 and the second by 1:

-3(x - 3y = 1)

1(3x - 5y = 11)

Becomes:

-3x + 9y = -3

3x - 5y = 11

Add the equations to eliminate x:

-3x + 9y = -3

3x - 5y = 11

4y = 8

Solve for y by dividing by 4:

4y/4 = 8/4

y = 2

Now we plug in y to the first equation:

x - 3 ( 2 ) = 1

x - 6 = 1

Add 6 to both sides:

x - 6 + 6 = 1 + 6

x = 7

trick question

Step-by-step explanation:

if ferris wheel A has a radius of 7.5ft=90in which you would multiplied by 2 which give a diameter of 180in and ferris wheel B has a diameter of 180in they would have the same circumference.

Answer:

i need question from this

Answer:

2

Step-by-step explanation:

The base B represents the number you multiply and the exponent "x" tells you how many times you multiply the base, and you write it as "B^ x." For example, 8^3 is 8X8X8=512 where "8" is the base, "3" is the exponent and the whole expression is the power.
