Hey there!

We know that each slice has 280 calories & we also know there are 6 equal pieces, so all we have to do is multiply 280 by 6 to find how many calories the entire pie is

280 * 6 = 1,680

Therefore, the whole pie has 1,680 calories

Hope this helps you!

God bless ❤️

A rectangular school banner has a length of 36 inches and a width of 52 inches. A sign is made that is similar to the school ban

zalisa [80]

Answer:

4212 : 1573 is the ratio.

Step-by-step explanation:

Given:

Length of rectangular school banner is 36 inches and width is 52 inches.

And, the sign made is similar to banner.

The sign's length is 22 inches.

Now, we have to find the ratio of the area of the banner to the area of the sign.

So, we have dimensions of rectangular school banner:

Length = 36 inches.

Width = 52 inches.

But, we have only length of sign:

Length = 22 inches.

Now, we have to find the width of sign by using cross multiplication method:

Let the width of sign be $x.$

As, sign is similar to banner.

So, if 36 inches is equivalent to 52 inches.

Then, 22 inches is equivalent to $x.$

$\frac{36}{52} =\frac{22}{x}$

By cross multiplying we get:

$36x=1144$

Dividing both sides by 36 we get:

$x=31\frac{7}{9} .$

Hence, the width of sign is $31\frac{7}{9}$ inches.

Now, we find the area of banner and the area of sign by putting formula:

Area of banner = length × width.

$Area\ of\ banner=36\times 52$

$Area\ of\ banner=1872\ square\ inches.$

Now, area of sign:

$Area\ of\ sign=length\times width\\\\Area\ of\ sign=22\times 31\frac{7}{9} \\\\Area\ of\ sign=22\times \frac{286}{9} \\\\Area\ of\ sign=\frac{6292}{9} \ square\ inches.$

Now, to get the ratio of the area of the school banner to the area of the sign:

$1872:\frac{6292}{9}$

$=\frac{1872}{\frac{6292}{9} } \\\\=\frac{16848}{6292}$

On simplifying we get:

$=\frac{4212}{1573}$

$=4212:1573.$

Therefore, the ratio of the area of the school banner to the area of the sign is 4212:1573.

Answer:

y = -5

Step-by-step explanation:

7y - 5 = 9y + 10 + y

7y - 5 = 10y + 10

3y + 10 = -5

3y = -15

y = -5

Using the properties of inequalities, write down the inequality that you will get if you: add the number –5; 2.7; 7; to both sid

puteri [66]

Answer:

See below

Step-by-step explanation:

1..........................

18 >−7

Add –5; 2.7; 7 to both sides

18 -5 > -7 - 5 ⇒ 13 > -12
18 + 2.7 > - 7 + 2.7 ⇒ 20.7 > - 43
18 + 7 > -7 + 7 ⇒ 25 > 0

2..........................

5 > -3

Subtract 2; 12; -5 from both sides

5 - 2 > -3 -2 ⇒ 3 > - 5
5 - 12 > -3 - 12 ⇒ -7 > -15
5 -(-5) > -3 - (-5) ⇒ 10 > 2

3..........................

- 9 < -6

Multiply both sides by 3; −3; −1

When multiplying both sides of inequality by positive number the sign stays as is, when multiplying both sides of inequality by negative number the sign reverses

-9 *3 < -6*3 ⇒ -27 < - 18
-9*(-3) > -6*(-3) ⇒ 27 > 18
-9*(-1) > -6*(-1) ⇒ 9 > 6

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 68 miles per hour, with a standard

Vladimir79 [104]

About 99.7% of vehicles whose speeds are between 59 miles per hour and 77 miles per hour.

Empirical rule states that for a normal distribution, 68% lie within one standard deviations, 95% lie within two standard deviations, and 99.7% lie within three standard deviations of the mean.

Given that mean (μ) = 68 miles per hour, standard deviation (σ) = 3 miles per hour.

68% lie within one standard deviation = (μ ± σ) = (68 ± 3) = (65, 71).

Hence 68% of the vehicle speed is between 65 miles per hour and 71 miles per hour.

95% lie within two standard deviation = (μ ± 2σ) = (68 ± 2*3) = (62, 74).

Hence 95% of the vehicle speed is between 62 miles per hour and 74 miles per hour.

99.7% lie within three standard deviation = (μ ± 3σ) = (68 ± 3*3) = (59, 77).

Hence 99.7% of the vehicle speed is between 59 miles per hour and 77 miles per hour.
