Answer:
34
Step-by-step explanation:
Let x represent the number of nickels Abby has. Then the number of dimes is 61-x. The total value of the coins, in cents, is ...
5x +10(61-x) = 440
-5x +610 = 440 . . . . . simplify
x - 122 = -88 . . . . . . . .divide by -5
x = 34 . . . . . . . . . . . . add 122
Abby has 34 nickels in her collection of coins.

The angle of elevation from a park bench 724 feet from the base of the Gateway Arch in St. Louis, Missouri is 22°. How tall is the Gateway Arch, rounded to the nearest whole number?
Answer:
Gateway Arch is [tex]292.46[/tex] feet tall
Step-by-step explanation:
As we know,
the horizontal distance from the gate of the Arch to the bench [tex]= 724[/tex] feet
The angle of elevation is [tex]22[/tex] degree
Let H be the height of the gate be "H"
Tanθ= Perpendicular/Base
Substituting the given values in above equation, we get -
[tex]tan 22 = \frac{H}{724} \\H = 724 * tan 22\\H = 724 * 0.404\\H = 292.46[/tex]feet
The length of one of the legs in a right triangle is
11 inches. The hypotenuse is 20 inches long.
What is the length of the other leg?
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] {c}^{2} - {b}^{2} = {a}^{2} [/tex]
[tex] {20}^{2} - {11}^{2} = {279}^{2} [/tex]
[tex] \sqrt{279} = 16.7 \: inches[/tex]
Length of the the other leg in the right triangle is 16.7 inches
What is right triangle?A triangle in which one of the interior angles is 90° is called a right triangle
Length of the one leg = 11 inches
Hypotenuse = 20 inches
Plot the figure using the given data
From the figure
[tex]AC^{2}=AB^{2}+BC^{2} \\BC=\sqrt{AC^{2}-AB^{2} } \\BC=\sqrt{20^{2}-11^{2} } \\BC=\sqrt{400-121} \\BC=\sqrt{279}[/tex]
BC= 16.7 inches
Hence, the length of the other leg is 16.7 inches

What is the Venn diagram?A Venn diagram is a diagram that helps us visualize the logical relationship between sets and their elements and helps us solve examples based on these sets. A Venn diagram typically uses intersecting and non-intersecting circles (although other closed figures like squares may be used) to denote the relationship between sets.
Let Math=M, Science=S and English=E
n(M)+n(S)+n(E)=1/2 (n(M∩S)+n(S∩E)+n(E∩M)
Let the number of students who study only one subject be x.
Let the number of students who study only two subjects be x/2.
n(M∩S∩E)=20
n(M∩S)+n(S∩E)+n(E∩M)=80
∪=x/2+80
∪=x+ x/2+20
Now, x/2+80 = x+ x/2+20
⇒ x=60
So, ∪=x/2+80 =110
Therefore, the total number of students in the survey is 110 students.

Step-by-step explanation:
Orchid wants to retile her bathroom floor, which has an area of 40 square feet. She is deciding between two types of custom tiles. The square tile is One-half foot by One-half foot and costs $0.45 per tile. The rectangular tile is 2 feet by One-fourth foot and costs $0.80 per tile.
Answer:
b. She should choose the rectangular tiles because the total cost will be $8 less.
Step-by-step explanation:
Which tile should Orchid choose to minimize costs? Explain.
a. She should choose the square tiles because the total cost will be $8 less.
b. She should choose the rectangular tiles because the total cost will be $8 less.
c. She should choose the square tiles because the total cost will be $14 less.
d. She should choose the rectangular tiles because the total cost will be $14 less.
Area of a square tile = 1/2 × 1/2
= 1/4
= 0.25 square feet
Area of rectangular tile = 2 × 1/4
= 2/4
= 0.5 square feet
Number of square tile needed = Area of the bathroom floor / Area of the square tile
= 40 square feet / 0.25 square feet
= 160
Number of square tile needed = 160
Cost of square tile needed = number of tiles × cost per tile
= 160 × $0.45
= $72
Cost of square tile needed = $72
Number of rectangular tile needed = Area of the bathroom floor / Area of the rectangular tile
= 40 square feet / 0.5 square feet
= 80
Number of rectangular tile needed = 80
Cost of rectangular tile needed = number of tiles × cost per tile
= 80 × $0.80
= $64
Cost of rectangular tile needed = $64
Cost of square tile needed = $72
Cost of rectangular tile needed = $64

Answer:
$13.50
Step-by-step explanation:
Hardcover Books = $18.25 each
Softcover Books = $5 each
She bought 2 hardcover and 2 softcover.
Hardcover: $18.25 + $18.25 = $36.50
We already know what 2 softcover books cost ($10)
No add those both together.
$36.50 + $10.00 = $46.50
She gives the clerk $60
$20 + $20 = 40
$20 + $20 = 40
$20 - $6.50 = $13.50

For which of the following conditions is it not appropriate to assume that the sampling distribution of the sample mean is approximately normal?
A random sample of 8 taken from a normally distributed population
A random sample of 8 taken from a normally distributed population
A
A random sample of 50 taken from a normally distributed population
A random sample of 50 taken from a normally distributed population
B
A random sample of 10 taken from a population distribution that is skewed to the right
A random sample of 10 taken from a population distribution that is skewed to the right
C
A random sample of 75 taken from a population distribution that is skewed to the left
A random sample of 75 taken from a population distribution that is skewed to the left
D
A random sample of 100 taken from a population that is uniform
Answer:
C
Step-by-step explanation:
Using the Central Limit Theorem, it is found that the option in which is it not appropriate to assume that the sampling distribution of the sample mean is approximately normal is:
C) A random sample of 10 taken from a population distribution that is skewed to the right
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.In option C, there is an skewed variable and a sample size less than 30, hence, the Central Limit Theorem is not applicable.

Find the midpoint of the segment with the given endpoints. (4,-4) and (7,-1)
Answer:
The midpoint is (5.5 , - 2.5)
Step-by-step explanation:
To get the midpoint of the line segment, we use the midpoint formula
We have this as follows;
(x,y) = (x1 + x2)/2 , (y1 + y2)/2
(x1,y1) = (4,-4)
(x2,y2) = (7,-1)
We have;
(x,y) = (4+7)/2 , (-4-1)/2
(x,y) = 11/2 , -5/2
(x,y) = (5.5, -2.5)

2. How can Diego package all the 64 cookies so that each bag has the same number of them? How many bags can he make, and how many cookies will be in each bag? Find all the possible ways to package the cookies.
:
Divide 64 by multiple numbers, and if they divide evenly that’s how many will be in each bag for the number of bags (number you divided by). For example, dividing 64 by 8 (bags) would be 8 cookies in each bag. You can do this with multiple numbers as long as it goes in evenly
Answer:
Step-by-step explanation:
All the factors of 64 work for this:
1, 2, 3, 4, 8, 16, 32, 64

Answer:
b
Step-by-step explanation:
The slope of b is 5.5 whereas the slope for the other three graphs are 5, so B is different from the rest.
A. (4, 0.8), so by rise over run, the slope is 4/0.8=5.
B. (55, 10), so 55/10=5.5.
C. (20, 4), so 20/4=5.
D. (50, 10), so 50/10=5.
Since B is the only graph with a slope of 5.5 and the other graphs have a slope of 5, the answer is B.
shine sold two tables at 9900 rupees each.he got 10% profit in one sale and 10% loss in the other.did the total sale result in a profit or loss? what percentage?
the total sale was neither a profit nor loss , 0%
Step-by-step explanation:
1st table :
100%-> 9900
110%-> 10890
10890-9900=990(earned)
------------------------------------------
2nd table :
100%->9900
90%-> 8910
9900-8910=990(lost)
990-990=0
hence the total sale was neither a profit nor loss , 0%
Joe and Sam shared a cheesecake cut into 12 pieces Joe ate three pieces and Sam ate five pieces what faction of the cheesecake did they eat in all show how you find your answer
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Just simply add along the top of the numbers.
1. We know that there were 12 pieces and out of those 12 Joe ate 3 pieces and Sam ate 5.
2. So now we have the two fractions [tex]\frac{3}{12}[/tex] and [tex]\frac{5}{12}[/tex] we simply add them together by adding across the top, we do not need to make any changes to the denominator due to the fact that they are parts of the 12 pieces of pie
3. after adding 3 + 5 you should get 8 and since the denominator will remain the same the answer should be [tex]\frac{8}{12}[/tex]
4. Now we must simplify we know 8 ÷ 4 = 2 and we can also divide 12 by 4 and that gets us 3 so make the numbers into a fraction, 3 should be on the bottom, and two on the top, and when you have your final answer your work should look somewhat similar to this:
[tex]\frac{3}{12}+\frac{5}{12} =\frac{8}{12} =\frac{2}{3}[/tex]
