Answer:
1250
Step-by-step explanation:
VOLUME = LENGTH X WIDTH
5 x 5 x 5 = 125 - volume of 1 cube
125 x 10 = 1250
Why do we multiply 125 by 10? There are 10 cubes and the volume of each is 125. To find the total volume, we would need to multiply.

Basic theorems on similarity of trianglesTheorem 1 :- SSS Similarity
When all the three sides of one triangle are in proportion to the other three sides of the another triangle then those 2 triangles are similar by SSS similarity .Theorem 2 :- AA similarity
When the two corresponding angles of one triangle are congruent to other two corresponding angles of another triangle then both the triangles are similar by AA Similarity .Theorem 3 :- SAS similarity
When the two sides of one triangle are in proportion to the other two sides of another triangle and the one of the angles of both the triangles that lie between two corresponding sides are equal then both the triangles are similar by SAS similarity.Theorem 4 :- AAA similarity
When all the three angles of one triangle are equal to other three angles of another triangle then both the triangles are similar by AAA similarity. Let's Begin :-Here, We have given statement that
" If an angle of one triangle is congruent to an angle of another triangle and the corresponding sides including those angles are in proportion, then the two triangles are similar . "From above theorem, we can conclude that
Both the triangles are similar by SAS similarityHence, Option C is correct
[tex]\bold{\huge{\underline{ Solution \: 2 }}}[/tex]
The given statement is proved by using Pythagorean theorem.
Pythagorean theorem states that the square of hypotenuse that is longest side is equal to the sum of the squares of base and perpendicular height that is the smallest sides of the given triangle.That is,
[tex]\sf{\red{ (Hypotenuse)^{2} = ( Perpendicular)^{2} + ( Base) ^{2}}}[/tex]
Hence, Option D is correct that is Pythagorean theorem.

The number of chairs Amal can paint varies directly with the amount of time she spends painting. Amal can paint 7 chairs in 3 hours. How many chairs can Amul paint in 15 hours? Enter your answer in the box.
Answer:
35
Explaination:
This problem can be represented by the equation: (7/3)=(x/15) Then solve for x, which is 35.
Amul can paint 35 chairs in 15 hours
Let the number of chairs Amal can paint be represented as N
And amount of time she spends painting be represented as t
such that
The number of chairs Amal can paint varies directly with the amount of time she spends painting will be expressed as
N∝t
Introducing the constant of proportionality,K becomes
N=Kt
Amal can paint 7 chairs in 3 hours.K becomes
N=Kt
7=K3
K=7/3
Now if Amul paint in 15 hours, she would paint
N=Kt
N=7/3 X 15
N=35 Chairs

How many whale sharks would a researcher need to measure so that 90% confidence level would have a margin of error of 0.25
About 1407 sharks would be needed to have a margin of error of 0.25
What is margin of error?
Margin of error is used to determine by what value there is deviation from the real value. Margin of error (E) is given by:
[tex]E=Z_\frac{\alpha}{2} *\frac{standard\ deviation}{\sqrt{sample\ size} }[/tex]
The 90% confidence level have a z score of 1.645. Hence for E = 0.25, standard deviation = 5.7 feet, hence:
[tex]0.25=1.645*\frac{5.7}{\sqrt{sample\ size}}\\ \\sample\ size=1407[/tex]

Using the formula below or Excel, find the correlation coefficient, r, for this set of scores. Answer choices are rounded to the nearest hundredth.
r equals fraction numerator 1 over denominator n minus 1 end fraction sum from blank to blank of open parentheses fraction numerator x minus x with bar on top over denominator s subscript x end fraction close parentheses open parentheses fraction numerator y minus y with bar on top over denominator s subscript y end fraction close parentheses
The correlation coefficient measures the relationship between the two variables
The correlation coefficient is 0.234
How to determine the correlation coefficientThe formula of correlation coefficient is:
[tex]r = \frac{1}{n - 1} * \sum{(\frac{x - \bar x}{\sigma_x})*(\frac{y - \bar y}{\sigma_y})[/tex]
Using the dataset from the complete question, we have:
[tex]r = \frac{1}{5 - 1} * 0.9375[/tex]
Evaluate the difference
[tex]r = \frac{1}{4} * 0.9375[/tex]

Step-by-step explanation:
[tex](A)\ 9y-252=4y\\(B)\ 5y=252\\(C)\ y= \frac{252}5 = 50.4[/tex]
In step A we multiplied both sides by the least common multiple of the denominators, in order to deal with only integers for as long as possible.
In step B you subtract 4y and add 252 to both sides ("moving them on the other end of the equal sign").
In step C you finally divide by 5 to isolate y.

explanation:

collect variables in one side
[tex]\sf 7y -9y +4y = 13 +4[/tex]
simplify by addition and subtraction
[tex]\sf 2y = 17[/tex]
divide both sides by 2
Hence, ,final answer:
[tex]\sf y = \dfrac{17}{2}[/tex]
Answer:
A. y = 17/2
Step-by-step explanation:
Given equation:
7y - 4 = 9y + 13 - 4y
Collect like terms:
7y - 4 = 9y - 4y + 13
Combine like terms:
7y - 4 = 5y + 13
Subtract 5y from both sides:
2y - 4 = 13
Add 4 to both sides:
2y = 17
Divide both sides by 2:
y = 17/2

Blaine is selling tickets to a rock concert. Tickets in the front section cost $60 each. Tickets in the back section cost $40
each. Blaine has 55 tickets left to sell, and to meet his sales quota he needs to sell more than $600 in tickets from the
remaining tickets.
Blaine makes a profit of $40 on every ticket for the front section. He makes a profit of $25 on every ticket for the back
section. What's the maximum profit Blaine can make from selling his remaining tickets?
You may find it helpful to review the steps of linear programming e.
Part A
Write the system of inequalities for the given situation where x represents the number of front section tickets and y
represents the number of back section tickets.
Answer:
25 tickets more
Step-by-step explanation:
I got x+y is (less than or equal to) 55 for the first inequality and 60x+40y>600 for the second one!
Step-by-step explanation:
Since Blaine can sell a maximum of 55 tickets, the first inequalitly is x+y is less than OR EQUAL TO 55. Since the tickets in the back section cost $40 each, 40y represents the money made from those tickets. Blaine needs to make 600 in sale so the inequality is 60x+40y>600.
If 2 L of water is mixed with 4.5 L of milk and filled into 650 mL cans. Then
cans will be needed to fill the mixture.
The numbers of can required to fill the mixture is 10 cans
Data;
Volume of water = 2Lvolume of milk = 4.5Lvolume of cans = 650mL = 0.65LNumber of Cans Required to fill the mixtureTo find the numbers of can required to fill the mixture, let's add the volume of the mixture.
volume of mixture = volume of water + volume of milk
volume of mixture = [tex]2 + 4.5 = 6.5L[/tex]
The entire volume of the mixture is 6.5L.
To find the numbers of cans that'll fill the mixture, let us divide 6.5 by 0.65.
Number of can required = [tex]\frac{6.5}{0.65} = 10[/tex]
From the calculation above, we would need 10 cans to fill the mixture.

5.16 Identify hypotheses, Part II: Write the null and alternative hypotheses in words and then symbols for each of the following situations. (a) Since 2008, chain restaurants in California have been required to display calorie counts of each menu item. Prior to menus displaying calorie counts, the average calorie intake of diners at a restaurant was 1100 calories. After calorie counts started to be displayed on menus, a nutritionist collected data on the number of calories consumed at this restaurant from a random sample of diners. Do these data provide convincing evidence of a difference in the average calorie intake of a diners at this restaurant?
Answer:
H₀: µ = 1100 vs. Hₐ: µ ≠ 1100.
Step-by-step explanation:
A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.
It is a hypothesis of no difference.
It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.
For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.
Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.
The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.
It is also known as the research hypothesis and is denoted by Hₐ.
In this case the hypothesis can be defined as follows:
Null hypothesis:
H₀: The average calorie intake of a diner at this restaurant is 1100, i.e. µ = 1100.
Alternate hypothesis:
Hₐ: The average calorie intake of a diner at this restaurant is different from 1100, i.e. µ ≠ 1100.
