Step-by-step explanation:
A pizza is cut into six unequal slices (each cut starts at the center). The largest slice measures 90 degrees: If Larry eats the slices in order from the largest to the smallest, then the number of degrees spanned by a slice decreases at a constant rate. (So the second slice is smaller than the first by a certain number of degrees, then the third slice is smaller than the second slice by that same number of degrees, and so on.)
What is the degree measure of the fifth slice Larry eats?
Can someone explain how they got the answer and what numbers to use?
Answers
9514 1404 393
Answer:
42°
Step-by-step explanation:
The problem tells you the degree measures form an arithmetic progression. The sum of the 6 terms of the progression is 360, and the first term is 90.
The sum of n terms of an arithmetic progression is given by ...
Sn = (a1 +d/2(n -1))n
For Sn = 360, a1 = 90, n = 6, we have ...
360 = (90 +d/2(5))(6)
Dividing by 6 and subtracting 90 gives ...
-30 = 5/2d
Multiplying by 2/5, we find the number of degrees difference to be ...
d = -12
Then the 5th term of the sequence is ...
an = a1 +d(n -1)
a5 = 90 -12(5 -1) = 90 -48 = 42
The 5th slice Larry eats has a measure of 42 degrees.
_____
The slices measure 90, 78, 66, 54, 42, 30 degrees.

An object has velocity of 8 m/s and kinetic energy of 480j what is the mass of the object
Answers
==============================================
Work Shown:
KE = 480
v = 8
KE = (1/2)*m*v^2
480 = 0.5*m*8^2
480 = 0.5*m*64
480 = 0.5*64m
480 = 32m
32m = 480
m = 480/32
m = 15
The SI unit for mass is in kilograms
Also a joule is defined with kilograms since 1 J = 1 kg*m/s^2
1 joule is the amount of energy needed to move an object of mass 1 kg with an acceleration of 1 m/s^2
So this is why the mass m is in kilograms.

How many gallons of pure alcohol should be added to 40 gallons of a 20% solution so
that a mixture is 25% alcohol?
Answers
Answer:
8/3
Step-by-step explanation:
i put equations as this:
x+40 = y
where x is galllons of pure mixture and y is the gallons of the new mixture
the other equation i id was:
x+0.2(40) = 0.25y
x+8 = 0.25y
y = 4x+32
solve using substitution
(x+40) = 4x+32
x = 4x-8
-3x = -8
x = 8/3
A cake is made from the ingredients listed below.
500 g flour, 450 g butter, 470 g sugar,
1.8 kg mixed fruit, 4 eggs (70 g each)
The cake loses 12% of its mass during cooking.
What is its final mass?
Answers
To make a cake :-
Quantity of flour needed = 500 g
Quantity of butter needed = 450 g
Quantity of sugar needed = 470 g
Quantity of mixed fruit needed = 1.8 kg = 1000 g + 800 g
Quantity of eggs needed = 70 × 4 = 280 g
It's weight after adding all the ingredients =
=500 + 450 + 470 + 1000 + 800 + 280
= 3500 g
Mass that got lost while baking the cake :
= 12 % of 3500[tex] = \frac{12}{100} \: of \: 3500[/tex]
[tex] = \frac{12}{100} \times 3500[/tex]
[tex] =\frac{(12 \times 3500)}{100} [/tex]
[tex] =\frac{42000}{100} \: g[/tex]
[tex] = 420 \: g[/tex]
Final mass = Initial mass - mass that got lost
[tex] = 3500 - 420 \: g[/tex]
[tex] = 3080 \: g[/tex]
∴ The final mass of the cake is 3080 g .

Answers
Answer:
a. Wolfe, Lin, and Critchlow
Explanation:
We choose random sample of subjects based on the first random number from left to right and since 4(number appears two times so we wait for next different number) and 9 come first we choose Wolfe and critchlow. The third Subject as we have to choose 3 subjects per sample is Lin since her number 8 appears next. Also the order doesn't matter so we could have Wolfe, Lin, and Critchlow or Critchlow, Lin, Wolfe or in any other order
Round to the nearest ten to estimate the difference of 789-371
Answers
Answer:
420
Step-by-step explanation:
Subtract the numbers
789 - 371
Sum:
418
Remember, we did not necessarily round up or down, but to the ten that is nearest to 418.
First, 418 rounded to the nearest ten is
420
When rounding to the nearest ten, like we did with 418 above, we use the following rules:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

Answer:
∠7 = 102°
Step-by-step explanation:
∠2 ≅ ∠6 [Corresponding Angles]
So,
∠6 = 78°
Now,
∠6 + ∠7 = 180°
Where ∠6 = 78°
78° + ∠7 = 180°
∠7 = 180° - 78°
∠7 = 102°

A political analyst believes that a senator's recent decision to support a bill resulted in a drop of approval ratings. To test this claim, he selects random cities in the state the senator represents and compares the approval ratings before the decision to the approval ratings after the decision. Suppose that data were collected for a random sample of 8 cities, where each difference is calculated by subtracting the percent approval rating before the decision from the percent approval rating after the decision. Assume that the ratings are normally distributed. Using a test statistic oft -3.935, the significance level Q=0.05, and the corresponding p-value less than 0.01, draw a conclusion for the appropriate hypothesis test, where the null hypothesis is H. : = 0 and the alternative hypothesis is H. : < 0.

a. Reject the null hypothesis.
b. Fail to reject the null hypothesis.
c. The conclusion of the hypothesis test is that there is sufficient evidence to suggest that there was a drop in approval ratings in cities after the decision to support the bill.
d. The conclusion of the hypothesis test is that there is insufficient evidence to suggest that there was a drop in approval ratings in cities after the decision to support the bill.
Answer:
The correct option is a and c
Step-by-step explanation:
From the question we are told that
The sample size is n = 8
The test statistics is t = -3.935
The level of significance is [tex]\alpha = 0.05[/tex]
The p-value is [tex]p-value = 0.01[/tex]
From the data given we see that the [tex]p-value < \alpha[/tex] hence
The decision rule is
Reject null hypothesis
The conclusion
There is sufficient evidence to suggest that there was a drop in approval ratings in cities after the decision to support the bill.
