Answer:

4(2x2+4x−6;) 130.0 inches

Step-by-step explanation:

The expression that can be used for the total length of ribbon she needs for both square pillows and the length if x = 3.5 is:

D. 4(2x² + 4x - 6); 130.0 inches.

Perimeter of a square = 4(s).

s = side length of the square.

Perimeter of the first pillow = 4(s) = 4(2x² + 1) inches.

Perimeter of the similar pillow = 4(s) = 4(4x - 7) inches.

Expression for the total length of ribbon she will need for both square pillows is:

4(2x² + 1) + 4(4x - 7)

4(2x² + 1 + 4x - 7)

4(2x² + 4x - 6)

If x = 3.5, plug in the value of x into 4(2x² + 4x - 6) to find the total length of the ribbon she needs:

4(2(3.5)² + 4(3.5) - 6)

4(24.5 + 14 - 6)

130.0 inches.

Thus, the expression that can be used for the total length of ribbon she needs for both square pillows and the length if x = 3.5 is:

D. 4(2x² + 4x - 6); 130.0 inches.

Answer:

5.27 lb

Step-by-step explanation:

Given that,

Mya has 3 times as much floor as Eric. Mya has 15.81 lb of floor. The relation is given by :

Let Eric has F floor.

3F = 15.81 ...(1)

We need to find how much flour Eric has.

Dividing both sides by 15.81.

F = 15.81/3

F = 5.27 lb

Hence, Eric has 5.27 lb of flour.

Answer:

Guitarist wtote 25 songs

Drummer wrote 10 songs

Step-by-step explanation:

G: number of guitarist songs

D: number of Drummer songs

We have:

G=3D - 5 (The guitarist wrote 5 fewer than three times the number of songs that the drummer wrote)

G+D=35 (They wrote a total of 35 songs)

That is the meaning of each equation.

Now we have to solve these system of equations:

G=3D-5

G+D=35

Using the substitution method:

(3D-5)+D=35

4D=35+5

4D+40

D=10

Thus: G=35-10

G=25

9. a. 6

9. b. 2; 1

9. c. 3.14; 1.57

9. d. 7.57

10. 3106.86

Step-by-step explanation:

9.  a.  The rectangle has a length of 3 and a width of 2, so that means its area has to be 6.

9. b. The semi-circle's diameter is 2, because it is the same width as the rectangle, and finding the radius, means that you need to cut the diameter in half, so the radius of the circle is 1.

9. c. To find the full circle, we must use the formula (pi)(r)^2. So we have 3.14(1), which is just equal to pi. but since we need half the circle, we must divide the number by 2, to get the answer 1.57...

9. d. Finally we need to add up all the values together, from a. we know that the rectangle has an area of 6, and from b and c, we know the semi-circle has an area of 1.57, so we add those two numbers together we get 7.57.

10. We can do the exact same thing as number nine, which means the rectangle is 30*70=2100, The radius of the circle is 15 (30/2), the area of the circle (and since there are 2 semi circles, we don't need to divide by 2) we get 706.86, now all thats left is to add the numbers together to get the number 2806.86.

What is the total number

Step-by-step explanation:

Answer:

0.527

Step-by-step explanation:

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 6, 4, 8/3... Find the 7th term

The sequence given in the above Question is a geometric sequence.

The formula for the nth term of a geometric sequence is given as:

an = a × r ^n - 1

Where

a = First term

r = Common ratio

n = nth term

From the above question, we are asked to find the 7th term

Hence:

a = 6

Common ratio = Second term/first term

= 4/6 = 2/3

n = 7

The 7th term = 6 × (2/3 )^7 - 1

= 6 × (2/3)^6

= 6 × (2/3)⁶

= 0.5267489712

Approximately to the nearest thousandths the 7th term = 0.527

Answer:

7. A=48

8.B=30

9. C=188

10. D=18

11. X=32

12.Y=40

Step-by-step explanation:

Answer:

7. [tex]a=48[/tex]

8. [tex]b=30[/tex]

9. [tex]c = 188[/tex]

10. [tex]d = 18[/tex]

11. [tex]x = 32[/tex]

12. [tex]y = 40[/tex]

Step-by-step explanation:

Let's do something called cross-multiplication. It's exactly what it sounds like, we multiply the top number with the denominator across the multiplication.

[tex]\frac{33}{a} = \frac{11}{16}[/tex]

[tex]11 a = 33(16)[/tex]

[tex]11a = 528[/tex]

Now we can simplify.

[tex]a=48[/tex]

So we got the answer for the first one. We can keep doing the same thing for the others.

Answer:

His sales that week were $2,160.

Step-by-step explanation:

First, you have to subtract $324 from the amount he earned that week, to find the 5% he got from sales:

$432-$324=$108

Now, you know that he received $108 that represent 5% of his sales and you can use a rule of three to find the amount that represents 100% which would be his sales that week:

 5%   →    108

100% →      x

x=(100*108)/5=2160

According to this, the answer is that his sales that week were $2,160.

The afternoon temperature in Westfield City is -10°F.

Martin is not correct.

From the question, we are to determine the afternoon temperature in Westfield City

From the given information,

"In the morning, the temperature in Westfield City was -2°F"

and

"By afternoon, a north wind caused the temperature to drop another 8°F"

Thus,

The afternoon temperature = -2°F - 8°F

The afternoon temperature = -10°F

Hence, the afternoon temperature in Westfield City is -10°F.
