For △ABC find the length of AB if AC=7, BC=5, and m∠C=20. Round your answer to the nearest hundredths. (Image not drawn to scale)

Answer:

28 students

Step-by-step explanation:

The easiest way to solve this would be to set up an equation.

We can start by naming x the number of students in Reggie's class.

Therefore, our equation would be:

0.75x=21

We can get this by knowing 75% of the students brought their lunches, and there were 21 students that did.

75% is equivalent to 75/100 which is 0.75.

Next, we can solve the equation.

0.75x=21

To do this, we have to isolate x.

We need to reverse the multiplication with division.

We can do this by dividing both sides by 0.75 (What you do to one side you must do to the other)

0.75x/0.75=21/0.75

x=28

This means that there are 28 students in the class.

Step-by-step explanation:

In Reggie's class, 75% of the students brought their lunches on

Monday. If 21 students brought their lunches, how many students

are in the class in all?

28 students

Answer:

26 customers

Step-by-step explanation:

Represent customers entering as y and those buying hot dogs as x

[tex]y = 4x + 9[/tex]

[tex]y = 3x + 35[/tex]

Required

Determine the number of people buying hotdogs (x)

Substitute 4x + 9 for y in the second equation

[tex]4x + 9 = 3x + 35[/tex]

Collect Like Terms

[tex]4x - 3x = 35 - 9[/tex]

[tex]x = 26[/tex]

Answer:

2:6

Step-by-step explanation:

You spin it 6 times, you have a chance of getting two options

^^ this is a guess but it seems pretty reasonable

The best prediction possible for the number of times the spinner will land on yellow if it is spun 6 times is 1.

If the spinner has 12 equal parts and 2 of them are yellow, then the probability of the spinner landing on yellow is 2/12, or 1/6. This means that out of every 6 spins, we can expect the spinner to land on yellow once.

To find the best prediction for the number of times the spinner will land on yellow if it is spun 6 times, we can use the idea of expected value. The expected value of an event is the average value we would expect to see if the event were repeated many times.

Expected value = Probability of yellow x Number of spins

Expected value = (1/6) x 6

Expected value = 1

This means that out of 6 spins, we can expect the spinner to land on yellow approximately 1  times on average.

[tex]volume = ( \frac{3}{4} \times \frac{1}{2} ) \times \frac{5}{8} \\ [/tex]

[tex]volume = \frac{3}{8} \times \frac{5}{8} \\ [/tex]

[tex]volume = \frac{15}{8} \\ [/tex]

Answer:

0.23

Step-by-step explanation:

The equation for finding the volume of a cube is

length x width x height

so you need to multiply 5/8 by 1/2.

This will give you 5/16.

Now multiply 5/16 by 3/4.

This will give you 15/64 , which in decimal form will be your answer 0.23

Answer:

The width is 75.

Step-by-step explanation:

First you divide 324 by 2, because the formula is: 2(l + w)

324 ÷ 2 = 162.

Then I would subtract 162 by 87 because of the formula. (To find out width)

162 - 87 = 75

The width is 75.

You can double check by in-putting them into the above formula.

2(75 + 87) = 324

Answer:

268 increased by 75% of its value = 469

Step-by-step explanation:

hope this helps :))

The number when 268 is increased by 75%​ will be 469.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Let 'n' be the increased number. Then the equation is given as,

75% = [(n - 268) / 268] x 100

Simplify the equation, then we have

0.75 = (n - 268) / 268

n - 268 = 201

n = 201 + 268

n = 469

The number when 268 is increased by 75%​ will be 469.

Answer:

(b) Jo answered 4 which is the right answer.

Step-by-step explanation:

First, you have to remember PEMDAS which is parentheses, exponents, multiplication, division, addition, and subtraction.

In this case, you need to do 18/3 first because that is in the parentheses which always goes first.

Your answer should be 6 and you should write the question like this:
40-(6)^2

Now, you need to do the exponent next which is 6x6 not 6x2.

Remember, exponents, are the base which is the number 6 multiplied by itself to that many times so in this case, our base is 6 and the exponent says we need to have 6 multiplied to itself 2 times. 6x6

We like to say 6 to the power of 2 is 36.

So now you need to write the simplified equation to this:

40-36=n

Our n variable is a placeholder for our answer.

Now it's basic subtraction which is 40-36 = 4

Therefore, Jo had the right answer.

Finding the value of x

Answer:

$79.17

Step-by-step explanation:

91.00 x 0.13= 11.83 (the discount)

91.00-11.83= $79.17 (the sale price)

Answer: $71.17

Step-by-step explanation: If 91 is the original price and the discount rate is 13%, 13% of 91 is being taken off and 87% is remaining, to find the 87% that's remaining multiply the original (91) by the the remaining percent(87%).91 x .87=71.17

87%-->.87

87x.01=.87

To find the decimal form of a percentage multiply the percentage by .01.

The compass size should be the same for the whole process, be careful.

Make 90 degrees angle for both side and cross two arcs from each 90 degrees. The point thus obtained should be produced vertically towards the line AB. The point on the line segment is the line bisector.
