for an error. Chloe needs a 0.75 yard of fabric to make a skirt, so she cuts - 77… ... The directions on a sewing pattern say to cut a extra 15% of fabric to account for an error. Chloe needs a ... yard. Did Chloe cut the correct amount of fabric? ... No, Chloe cut only 15% of the .75 yards of fabric she needed

Answer:

No

Step-by-step explanation:

6/3=18/9

9/12=18/24

Also 6/3=2 and 2 does not equal 9/12

Answer:

The time it takes to boil 2.2 litres of water is approximately 141 seconds

Step-by-step explanation:

The given parameters are;

The relationship of the variables, T and A is a proportional, therefore, we have;

T ∝ A, or T/A = k = Constant of proportionality

The time it takes to boil 2.8 liters of water = 180 seconds

∴ When A = 2.8 litres, T = 180 seconds, from which we have;

k = T/A = 180 s/(2.8 L) = 450/7 s/L

k = 450/7 s/L

When A = 2.2 litres, we have;

T/A = k

∴ T = k × A

Plugging in the value for both 'k', and 'A' when A = 2.2 litres, gives;

T = k × A = 450/7 s/L × 2.2 L = 990/7 s = 141.[tex]\overline{428571}[/tex] s

The time it takes to boil 2.2 litres of water, given a direct proportionality relation is, T = 141.[tex]\overline{428571}[/tex] seconds ≈ 141 seconds given to the nearest second.

Answer:

10

Step-by-step explanation:

Since the Y axis is the same you add 3+|-7|

so thats 10, which makes your answer 10

Complete question :

In which number does the digit 3 have a value that is 10 times as great as the value of the digit 3 in 143,728? 137,982 142,398 292,389 392,097

Answer:

137,982

Step-by-step explanation:

The value of digit 3 in 143, 728

3 in 143,728 is in the 1000 thousand place, hence, digit 3 has a value of :

3 * 1000 = 3000

Therefore, 10 times the value of digit 3 will be :

3000 * 10 = 30000

Feom the options given, we obtain the option where 3 has a value of 30000 if the number is expressed in expanded form:

The answer is 137,982

3 here is in the 10 thousand place = 3 * 10,000 =. 30,000

Answer:

x = 12, y = 8

Step-by-step explanation:

Since we know that the two triangles are similar that means we can find the ratio. The larger triangle is two times larger, we can find that out using 7/3.5 = 2. That means x + 4 = 2y and 3y = 2x. We can solve for y using substitution. We can double the first equation. 2x + 8 = 4y. We know that 2x = 3y so we can plug that in. 3y + 8 = 4y. Solving for y, gets us y = 8. Now we can plug that into any of the prior equations. I'll use 3y = 2x. 3(8) = 2x. 24 = 2x. Divide both sides by 2. x = 12.

Answer:

To find the circumference you need to use C= 2πr but since you started with the diameter you need to divide it by 2 and you will get 3963.2. After you get the radius use the formula C= 2πr and you will get 24901.52

The equation would be written as 2 x π x 3963.2 = 24901.52

Answer:

x = 22

Step-by-step explanation:

x = 7 + 15

x = 22

Answer:

x = 22

Step-by-step explanation:

1x - 7 = 15

1x = 15 + 7

1x = 22 (divide both sides by the first number/1 to get x)

1x/1 = 22/1

x = 22

Answer:

680

Step-by-step explanation:

What we should know is how many words he can type in 1/4 minutes. We can do 110 divided by 2.75 which is 40. 40 is the number of words he can type in 1/4 minutes. Now multiply this 17 (4 1/4 = 17/4) and you get 680. I believe he can type 680 words in 4 1/2 minutes. (Make sure my answer is correct)

Answer:

6

Step-by-step explanation:

2 + (1/10)(1/5)(1/10)2000 = 2 + (1/500)(2000) = 2 + 4 = 6

The number that is two more than one-tenth of one-fifth of one-tenth of 2,000​ will be 6.

The ratio is the division of two numbers while multiplication is an operation in mathematics to multiply two or more values to get a multiplied number.

Proportion is the relation of a variable with another. It could be direct or inverse.

The one-tenth of x = (1/10)x similarly

one-tenth of one-fifth of one-tenth = (1/10)(1/5)(1/10)

So  one-tenth of one-fifth of one-tenth of 2,000​ =  (1/10)(1/5)(1/10) ×2000

⇒ 2000/500 = 4 Now the question is saying 2 more hence

⇒ 4 + 2 = 6 hence six will be the correct answer.

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

We can work backwards.

First, notice that we have an open circle. So, we do not have "or equal to." So, we can ignore A and B.

Our final answer is all values less than -3. So:

[tex]x<-3[/tex]

We can multiply both sides by 3:

[tex]3x<-9[/tex]

And then subtract 5 from both sides:

[tex]3x-5<-14[/tex]

So, the answer that matches this will be D.

Instead of working backwards, you can also just solve each inequality. Since we have an open circle, we only need to solve C and D. If we solve C, we get x > -3, and if we solve D, we get x < -3 (as desired). So, D matches the graph shown.

know what is the third side length

the difference between the 2 other sides <  the greatest side of triangle < the sum of 2 other sides

so here the answers here could be ( 10- 17 - 20)

10-8 < 13 <  10+8  

13-8 < 17 < 13+8

13-8 < 20 < 13+8

Answer:

Please check the explanation.

Step-by-step explanation:

When a point P(x, y) is reflected across the x-axis, all we need to do is to reverse the sign value of the y-coordinate of any given point while the x-value remains the same.

Thus,  

The rule to reflect over the x-axis is:  

P(x, y) → P'(x, -y)

In our case, the point, let's say A(0, 2), is reflected across the x-axis. Thus, the coordinates of A' will be:

P(x, y) → P'(x, -y)

A(0, 2) → A'(0, -2)

So, YES! point A(0,2) can be reflected across the x-axis and the coordinates of A' will be: A'(0, -2).

Answer:

 -4

Step-by-step explanation:

From the graph:

When n=2 , a^n =9

When n=4, a^n =1

The average rate of change between n=2 and n=4 is :

[tex]Rate= \frac{{{a_{2} -a_{4} } } }{2-4} \\=\frac{9-1}{-2} \\=-4\\[/tex]

The average rate of change is  -4
