To the nearest square meter, what is the curved surface area of the half pipe if it’s 7 m long?

The radius is 2.5 m

Answer:

A

Step-by-step explanation:

A is false because irrational numbers can not be integers.

Answer:

x = 3

Step-by-step explanation:

Perform the indicated multiplication.  We get  

8x - 6 - 8 = 4 + 2x

Combining the x terms results in:

6x - 14 = 4

Isolate x by adding 14 to both sides:

6x = 18

Find x by dividing both sides by 6:

x = 18/6 = 3

x = 3

The solution or the value of x for the given linear equation 2(4x-3)-8=4+2x is x = 3.

Given that:

2(4x - 3) - 8 = 4 + 2x

Use the distributive property on the left-hand side.

(2 × 4x - 2 × 3) - 8 = 4 + 2x

(8x - 6) - 8 = 4 + 2x

Using the associative property:

8x + (-6 - 8) = 4 + 2x

8x - 14 = 4 + 2x

Subtract both sides by 2x.

8x - 2x - 14 = 4

6x - 14 = 4

Add 14 on both sides.

6x = 18

Divide both sides by 6.

x = 3

Hence, the value of x is 3.

Answer:

a=1

Step-by-step explanation:

35a-29=14-8a

35a+8a=43a

43a-29=14

14+29=43

43a=43

A=1

Answer:

a=1

Step-by-step explanation:

first you distribute for 7(5a-4) so you get 35a - 28 - 1 =14 - 8a.

then you combine like terms so you get 35a - 29 =14 - 8a.

then you do it again which gives you 43a = 43.

divide both sides by 43 to get a by itself and you get a = 1

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

Explanation:

T = tens digit of original number

U = units digit of original number

"units digit" is the same as "ones digit"

The original number is in the form 10T+U. For example, let's say that T = 3 is the tens digit and U = 1 is the units digit. This means 10T+U = 10*3+1 = 31 is the original number. Though in this example, the digits don't add to 12.

To make the digits add to 12, we have the equation T+U = 12. This solves to U = 12-T which we'll use later.

--------------------

The digits are reversed to get the new number 10U+T and this is 15 times the original tens digit, so

new number = 15*(original tens digit)

10U+T = 15T

from here we plug in U = 12-T which we found earlier. This effectively eliminates or gets rid of the U variable to leave us with T only

10U+T = 15T

10(12-T)+T = 15T ..... replace U with 12-T

which we can now solve for T

--------------------

10(12-T)+T = 15T

120-10T+T = 15T

-9T+120 = 15T

120 = 15T+9T ... adding 9T to both sides

120 = 24T

24T = 120

T = 120/24 .... divide both sides by 24

T = 5

The original tens digit is T = 5

The original units digit is U = 12-T = 12-5 = 7

So the original number is 10T+U = 10*5+7 = 57

Flipping the digits gets us 75 which is 15 times that of the original tens digit of 5. The original number has its digits add to 5+7 = 12. The answer has been confirmed.

Answer:

Hi!

1.Well, let's try simplifying 4:18 so we can compare.

If we divide 4:18 by 2, we get 2:9  

We can see that 2:9 =/= 2:12

Thus, the two are not equivalent ratios.

2. 5:20 and 15:60 are equivalent, 5:20 x 3 to both numbers is 15:60

Therefore, It is equivalent.

3. 17 times 4 is 68 and 3 times 4 is 12. 17:3 and 68:12 are equivalent because you can times and divide them into each other

4. He read for 180 minutes.  

You can find that because every time he practices math for five minutes, he reads for 20, and 45 is 5, 9 times. So you multiply 20 by 9.

5. If he eats 3 slices in 2 minutes, he will have eaten 15 pieces in 10 minutes.

Answer:

4860 ft^2

Step-by-step explanation:

9 feet is represented by 1 inch.

● 9 => 1

Square both sides

● 81 => 1

So a 81 ft^2 square is represented by a 1 in^2 square (picture below)

■■■■■■■■■■■■■■■■■■■■■■■■■■

The gym's area in the blueprint is 60 in^2

That 60 1in^2 squares.

● 1 => 81

● 1×60 => 81×60

We have multiplied both sides by 60

● 60 => 4860

So the original are is 4860 ft^2

The actual square footage of the gym will be 4860 square feet.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

There is no effect of dilation on the angle.

The blueprint scale is 1 inch : 9 feet.

Then the scale factor will be (1/9).

If the gym's area is 60 square inches on the blueprint.

Then the actual square footage of the gym will be

⇒ 60 / (scale factor)²

⇒ 60 / (1/9)²

⇒ 60 x 81

⇒ 4860 square feet

Given the measure of the sides of rectangle A:

Length = 9in

Width = 3in

Get the dilation factor

Dilation factor k = ratio of the sides

k = 9/3

k = 3

This means that rectangle B must also have the same scale factor as A.

Answer:

y = 4x + 7

Step-by-step explanation:

parallel = same slope

y = 4x + b

plug in (-4, -9)

-9 = 4(-4) + b

-9 = -16 + b

b = 7

y = 4x + 7

Answer:

7=4x+7

Step-by-step explanation:

To do this you would just plug in (-4,-9) into the equation y=mx+b so we would get -9=4(-4)+b when you simplify you will get -9=-16+b so we would add 16 to both sides and we would get 7=b so we would know that the y intercept is 7 and we know that if a line is parallel to another line is just has a different b so for our equation we would get 7=4x+7

Answer

original speed X=10

Step-by-step explanation:

We know that Speed= distance/ time

Then

time =distance/speed

We were told the cyclist travels 40 km at a speed of x km/h.

Which means

Distance= 40km

speed =x km/h

Then time t =40/x

Again we we were told his speed was

reduced by 2 km/h

Then speed= (x-2)

But the Distance is still 40km

But we were told the difference in time is 1 hour

Time t=40/(x-2)

Then if we find the difference between the time t of the first condition and second condition we have

40/(x-2) - (40/x) =1

[40x-40(x-2)]/ x(x-2)= 1

80=x(x-2)

x^2-2x-80=0

This is a quadratic equation , if we solve using factorization we have

(x+8)(x-10)

x+8=0 or x-10= 0

X= -8 or 10

But we cannot have a negative value for speed then

X=10

Therefore, original speedX=10
