Answer:

A. 28

Step-by-step explanation:

95+57=152

180-152=28  (180 is sum of triangle, in order to find the angle measurement u have to subtract).

Answer:

32°

Step-by-step explanation:

Since the outer angle is 99°, the interior angle must be 180° - 99°. That is 81°. We then do the same for the outer angle 113°. So 180° - 113° is 67°. Since the angles of the interior angles must equal 180°, we add 81° and 67°. That equals 148°. Now to figure out x, 180° - 148° is 32°. I hope this helps! Please mark me brainliest!

Answer:

a = 3

Step-by-step explanation:

Simply substitute 2 for x and y for 1 and solve.

This will get you 2a + 2 = 8

Then simplifying, 2a = 6.

a = 3.

The value of a and the coefficient of x is 3.

Substitution means putting numbers in place of letters to calculate the value of an expression .

According to the given question.

We have a equation.

ax + 2y = 8.

Also, the solution to the equation is (2, 1).

So, substitute x = 2 and y = 1 in the equation ax + 2y = 8.

⇒ [tex]a(2) + 2(1) = 8[/tex]

⇒ [tex]2a + 2 = 8[/tex]

⇒ [tex]2a = 8-2[/tex]   ( subtracting 2 from both the sides)

⇒ [tex]2a = 6[/tex]

⇒ [tex]a = \frac{6}{2}[/tex]    (dividing both the sides by 2)

⇒ [tex]a = 3[/tex]

Hence, the value of a and the coefficient of x is 3.

Answer: 7.7%

Step-by-step explanation: First find the increase in height by subtracting 52 from 56. 56-52=4.

To find what percent this is of 52, divide 4 by 52. 4/52=0.0769. Then convert this from a decimal to a percent by multiplying by 100. 0.0769*100=7.69.

I just rounded it to the nearest tenth, you can change it how you need to.

Final answer:

The percent of increase in Angelica's height over one year, from 52 inches to 56 inches, is approximately 7.69%.

Explanation:

The student is asking how to calculate the percent of increase in height over a one year period. We start by finding the initial and final measurements, then calculate the increase and convert it to a percentage.

Angelica's initial height is 52 inches, and her final height after one year is 56 inches. The increase in height is 56 inches - 52 inches, which equals 4 inches. To find the percent increase, use the formula:

Percent increase= (Increase / Original amount) x 100

So, the calculation is

Percent increase= (4 / 52) x 100 = 7.69%

Therefore, the percent increase in Angelica's height is approximately 7.69%.

Answer:

C

Step-by-step explanation:

Since they left a tip of 20% you find 20% of 25.60, and then add it to 25.60.

You add 5.12 and 25.60 because it was a tip, they gave that much more.  

So 20% which is 5.12.  

25.60 + 5.12 = 30.72

since there were 3 people in total you just divide

30.72 / 3

= 10.24

Answer:

Answer:

When xy are zero multiply by 1.33 and we will find y only if x =70

So the linear function will be

y =  90/0 = 0    =   y = x/0

y =   90/2 = 2    =   y = x/2

y =    90/4 = 4   =  y = x/4

y =    90/8 = 6   = y = x/8

x=90  y = 60 when both = 0

Or we can reverse and do x2+2 and call train f(x) and train = x = 90.

Step-by-step explanation:

70/90 = 0.77  =  70 x 1.33 = 90 as a fraction percentage 77%

60/45= 1.33  =  70 x 1.33 = 90 / 2 = 45   ( and as 22.5 as a fraction percentage 133/3%)

50/22.5=2.22  =  70 x 1.33 = 90/4 = 22.5 as a fraction percentage  222.2%

40/11.25=3.55 =  70 x 1.33 = 90 /8 = 11.25  as a fraction percentage= 355.5%

Answer:

The length of the sides of the square is 9.0015

Step-by-step explanation:

Given

The diagonal of a square = 12.73

Required

The length of its side

Let the length and the diagonal of the square be represented by L and D, respectively.

So that

D = 12.73

The relationship between the diagonal and the length of a square is given by the Pythagoras theorem as follows:

[tex]D^{2} = L^{2} + L^{2}[/tex]

Solving further, we have

[tex]D^{2} = 2L^{2}[/tex]

Divide both sides by 2

[tex]\frac{D^{2}}{2} = \frac{2L^{2}}{2}[/tex]

[tex]\frac{D^{2}}{2} = L^2[/tex]

Take Square root of both sides

[tex]\sqrt{\frac{D^{2}}{2}} = \sqrt{L^2}[/tex]

[tex]\sqrt{\frac{D^{2}}{2}} = L[/tex]

Reorder

[tex]L = \sqrt{\frac{D^{2}}{2}}[/tex]

Now, the value of L can be calculated by substituting 12.73 for D

[tex]L = \sqrt{\frac{12.73^{2}}{2}}[/tex]

[tex]L = \sqrt{\frac{162.0529}{2}}[/tex]

[tex]L = \sqrt{{81.02645}[/tex]

[tex]L = 9.001469325[/tex]

[tex]L = 9.0015[/tex] (Approximated)

Hence, the length of the sides of the square is approximately 9.0015

Then we divide 182 dollars to the seven book in order to find a unit =182/7=26

To prove this answer multiply 26 dollars than 7 books and see if the outcome is 182.Then subtract 199 from 182 and see if you got 17.

Answer:

50.24 m^2

Step-by-step explanation:

Area of a circle = Pi r^2

Pi = 3.14

Diameter = 8 m

Radius r = diameter/2 = 8/2

Therefore

Area = 3.14 x 4^2

= 3.14 x 4 x 4

= 50.24 m^2

Answer:

The probability that both of the selected marbles are red is [tex]\frac{3}{28}[/tex]

Step-by-step explanation:

Given

Number of red marbles = 3

Number of blue marbles = 5

Required

Probability of selecting two red marbles (without replacement).

First, we need to get the total number of marbles

Total = Red Marbles + Blue Marbles

Total = 3 + 5

Total = 8

Probability is calculated by: Number of required outcome divided by number of possible outcome.

Since there are 3 red marbles out of a total of 8 marbles;

The probability that the first marble you selected is red is 3/8

From the question, you didn't return the marble back to the container.

This means that, there are 2 red marbles and a total of 7 marbles left in the container.

So, the probability that the next marble selected is red is 2/7

Let P(R and R) represent the probability of selecting two red marbles.

This is calculated by multiplying the probability of picking the first red marble and the second red marble.

Hence,

P(R and R) = [tex]\frac{3}{8} * \frac{2}{7}[/tex]

P(R and R) = [tex]\frac{6}{56}[/tex] --- Reduce to lowest term

P(R and R) = [tex]\frac{3}{28}[/tex]

Hence, the probability that both of the selected marbles are red is [tex]\frac{3}{28}[/tex]

To find Sandy's allowance, we use the given information to set up an equation. After solving it, we determine that Sandy's weekly allowance is $10.

To determine Sandy's weekly allowance, we need to work backward from the information given. We know that she ended with $13 after spending half of her allowance on movies and earning an additional $8 from washing the car. Let's let the variable A represent Sandy's allowance. According to the problem, Sandy spent A/2 on movies, and when she added the $8 she earned, she had $13.

We can set up the equation as follows:

Now, we solve for A to find the allowance:

So, Sandy's weekly allowance is $10.
