Margot is sewing a ribbon on a seam along the perimeter of a square pillow. The side length of the pillow is 2x2+1 inches. She plans to make a similar pillow, including the ribbon, whose side length is 4x−7 inches. What expression can be used for the length of ribbon that she needs for both pillows, and what is the length if x = 3.5?
2x2+4x−6; 22.0 inches
2x2+4x−6; 32.5 inches
4(2x2+4x−6;) 88.0 inches
4(2x2+4x−6;) 130.0 inches
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.
What is the Perimeter of a Square?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.

A plane rises from take off and flies at an angle 11° with the horizontal runway. When it has gained 750 feet find the distance to the nearest foot the plane has flown
Answer:
[tex]D=3930.632298 \approx 3930.6miles[/tex]
Step-by-step explanation:
From the question we are told that
Angle [tex]\theta=11\textdegree[/tex]
Height of plane [tex]h =750feet[/tex]
Generally the equation for the total distance flown is mathematically given by
[tex]D=\frac{h}{sin\theta}[/tex]
[tex]D=\frac{750}{sin11}[/tex]
Therefore total distance flown is
[tex]D=3930.632298 \approx 3930.6miles[/tex]
Mya and ERIC WORK IN A BAKERY . MYA HAS 3 TIMEA AS MUCH FLOUR AS ERIC .MYA HAS 15.81LB OF FLOUR .USE THE EQUATION 3F = 15.81 TO FIND HOW MUCH FLOUR ERIC HAS .
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.

A drummer and a guitarist each wrote songs for their band. The guitarist wrote 5 fewer than three times the number of songs that the drummer wrote. They wrote a total of 35 songs. Which system of equations models this situation if the drummer wrote d songs and the guitarist wrote g songs? *
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

a north wind caused the temperature to drop another 8°F. What was the
afternoon temperature in Westfield City? To solve the problem, Martin
subtracted -2-(-8) and came up with an answer of 6°F. Is Martin correct?
Why or why not?
The afternoon temperature in Westfield City is -10°F.
Martin is not correct.

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.

The equation of a straight line is y = 20 – X.
If the x value of a point on the line is 14, what is the y value of this point?
Given:
The equation of a straight line is
[tex]y=20-x[/tex]
The x value of a point on the line is 14.
To find:
The y value of this point.
Solution:
If a point (x,y) lines on line, then the equation of line must be stratified by that point.
We have, the equation of a straight line.
[tex]y=20-x[/tex]
Putting x=14, we get
[tex]y=20-14[/tex]
[tex]y=6[/tex]
Therefore, the y-value is 6 when the x-value is 14.
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 6, 4, 8/3... Find the 7th term.
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

James works in a sporting goods store and earns $324 a week and 5% of his sales. One week James earned $432. What were his sales that week?
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.
