The linear scale factor of two similar solids is given. Then the surface area and volume of the smaller figure are also given. Find the surface area and volume of the large figure.
Scale factor: 4:5
Surface area: 160
volume: 704
Surface area: ?
volume: ?
Answer:
Surface area: 250
Volume: 1375
Step-by-step explanation:
Scale factor: 4:5
This means that the dimensions of the larger figure are 5/4 of those in the smaller figure.
Surface area:
The surface area is found multiplying the square of the change(5/4) by the original surface area(160). So
[tex]S = (\frac{5}{4})^2 \times 160 = \frac{25}{16} \times 160 = 25 \times 10 = 250[/tex]
Volume:
The volume is found multiplying the cube of the change(5/4) by the original volume(704). So
[tex]S = (\frac{5}{4})^3 \times 704 = \frac{125}{64} \times 704 = 125 \times 11 = 1375[/tex]
Diane is making chair covers to sell. She has a bolt of fabric that is 20 yards long. If each chair requires 3 2/5 yards of fabric, how many chair covers will Diane be able to make
Answer: alo mwen panse ke li ta dwe 3/6
Step-by-step explanation:
ou konnen mwen te u konsa 7 ajoute ke epi pou yo jwenn 10 shawty
The number of chair covers Diane will be able to make is 5.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Length of the fabric = 20 yards
Length of fabric needed for each chair cover = 3(2/5) yards
The number of chair covers that can be made with 20 yards.
= 20 ÷ 3(2/5)
= 20 ÷ 17/5
= 20 x 5/17
= 100/17
= 5.8
= 5
Thus,
The number of chair covers is 5.

Question 15: x = 17
Question 16: area = 5610 units
Step-by-step explanation:
Question 15:
The perimeter is the sum of all sides of a triangle.
It is given that the perimeter is 374 units.
[tex]p = 8x - 4 + 9x + 4 + 4x + 17[/tex]
[tex]374 = 8x - 4 + 9x + 4 + 4x + 17[/tex]
Add all the like terms.
[tex]374 = 21x + 17[/tex]
Subtract 17 from both sides.
[tex]357 = 21x[/tex]
Divide by 21 from both sides.
[tex]17 = x[/tex]
Question 16:
The area of a triangle can be found by using the following formula:
[tex]a = \frac{1}{2} bh[/tex]
(where a is the area, b is the base, and h is the height)
Using the value of x you just found previously (17), you can calculate the base and height by substituting 17 with x in their respective equations.
[tex]h = 8x - 4[/tex]
[tex]h = 8(17) - 4[/tex]
[tex]h = 134[/tex]
[tex]b = 4x + 17[/tex]
[tex]b = 4(17) + 17[/tex]
[tex]b = 85[/tex]
Now that you found the base and height, substitute the values, 134 and 75, into the area of a triangle formula.
[tex]a = \frac{1}{2} bh[/tex]
[tex]a = \frac{1}{2} (85)(132)[/tex]
[tex]a = 5610[/tex]
write the 0.216 in the form of p by q
Answer:
27/125
Step-by-step explanation:
Given the decimal value 0.216, we are to express as a fraction in the fofrm of p/q
0.216 = 216/1000
216/1000 = 2 * 108/2 * 500
216/1000 = 108/500
108/500 = 4*27/4*125
108/500 = 27/125
Hence the expression in form p by q is 27/125

Suppose that a random sample of 10 adults has a mean score of 62 on a standardized personality test, with a standard deviation of 4 . (A higher score indicates a more personable participant.) If we assume that scores on this test are normally distributed, find a 90% confidence interval for the mean score of all takers of this test. Then find the lower limit and upper limit of the 90% confidence interval.
Answer:
The 90% confidence interval for the mean score of all takers of this test is between 59.92 and 64.08. The lower end is 59.92, and the upper end is 64.08.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.9}{2} = 0.05[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.05 = 0.95[/tex], so [tex]z = 1.645[/tex]
Now, find the margin of error M as such
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 1.645*\frac{4}{\sqrt{10}} = 2.08[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 62 - 2.08 = 59.92
The upper end of the interval is the sample mean added to M. So it is 62 + 2.08 = 64.08.
The 90% confidence interval for the mean score of all takers of this test is between 59.92 and 64.08. The lower end is 59.92, and the upper end is 64.08.

Step-by-step explanation:
y = -x-5
Slope of line is -1.
Slope of perpendicular to line is 1.

y-2 = 1(x-6)
Rearrange equation to slope-intercept form:

Zada needs to simplify the expression below. 72 – 4 × 12 ÷ 6 Which solution for Zada’s expression is correct?
F. 408, because 72 – 4 is 68, 12 ÷ 6 is 6, and 68 × 6 is 408
G. 64, because 4 × 12 is 48, 48 ÷ 6 is 8, and 72 – 8 is 64
H. 4, because 4 × 12 is 48, 72 – 48 is 24, and 24 ÷ 6 is 4
J. 136, because 72 – 4 is 68, 68 × 12 is 816, and 816 ÷ 6 is 136
Answer:
order of operations matter here so
72 - 4 × 12 ÷ 6
start with 4 × 12 (which equals 48)
72 - 48 ÷ 6
next is 48 ÷ 6. (which equals 8)
72 - 8 = 64
so g is correct

Number of stars: 2+2+2+2+2+2
=6×2
Step-by-step explanation:
The stars are added in pairs of two. The pair that is 2+2+2+2+2 is five groups of 2 or 2 groups of five.
Since another pair of two wad added, there is one more pair. Instead of 5×2
Which means 5 groups of 4, it is not 6 groups of 2. I hope I helped you! Have a good day :3
