Answer:

80

Step-by-step explanation:

ㄥAEC+160=180

ㄥAEC=20

ㄥAEC+x+80=180

20+x+80=180

x=80

There is a more simple method

x+80=160

x=80

Answer:

35x+55 = 160

Step-by-step explanation:

Cost equal flat rate plus rate per hour times hours  where x is the number of hours worked

cost = 55 + 35x

160 = 55 + 35x

Rewriting

35x+55 = 160

Answer: 4.6 cattle

Step-by-step explanation:

Since you are finding the average, you have to...

Step 1: Add all of the numbers:

4 + 1 + 9 = 14

Step 2: Divide 14 by 3 (the amount of numbers added)

14 ÷ 3 = 4.666666666667 (to be exact)

Answer:

abot 18

Step-by-step explanation:

The constant rate of change is how much y increases every time x increases by 1. We might be confused because in this table, we see a number of points, but we don't see any consecutive x-values, so it might seem difficult. But no worries!

All you have to do is calculate using the formula, Δy divided by Δx. What does Δy divided by Δx mean?

All we have to do is look at two points. Let's take, for example, (-2, -10) and (2, -8).

-2 and 2 are the x-values of the points and -10 and -8 are the y-values of the points as coordinates are in the format of (x, y).

All we have to do is minus the y-coordinates and then proceed the minus the x-coordinates. The order does not matter, as in you can do either of these ways:

[(-10) - (-8)] ÷ [(-2) - (2)] = -2 / -4 = 1/2

or

[(-8) - (-10)] ÷ [(2) - (-2)] = 2 / 4 = 1/2

So the constant rate of change or the answer is 1/2.

Answer:

U=2

Step-by-step explanation:

This is a simple one-step algebraic equation. In algebra to solve equations, you should use the properties of equality. The properties say that an equation remains true as long as the same thing happens on both sides. For this equation, the property of subtracting should be used; this property states that the same number can be subtracted from both sides. To find U, isolate the variable by subtracting 2 from both sides. This leaves U=2.

Answer:

AC=2.868

Step-by-step explanation:

using pythagoras theorem

take 35 degree as reference angle

hypotenuse =5 , opposite =AC , adjacent=BC

using sin rule

sin 35=opposite/hypotenuse

0.5735=AC/5

0.5735*5=AC

2.8675=AC

2.868=AC

Answer:

39 square yards

Step-by-step explanation:

The base is a square, so the area is 3 x 3 = 9.

Each side is a triangle, and the formula for that is (1/2)(base)(height)

The base of each side is 3 and the height of each is 5. There are 4 of those, so it's 4 x (1/2)(3)(5) = (2)(3)(5) = 30

Add the base and sides

30 + 9 = 39

Answer:

39 yards

Step-by-step explanation:

surface area = A + [tex]\frac{1}{2}[/tex] ps

A = area of the base

p = perimeter of the base

s = slant height

the base of the pyramid is a square, all sides and angles are equal

; 3 yards

; area of a square  = l x w

; area of the base = 9 yd (A)

perimeter of the base ; 3 + 3 + 3 + 3 = 12 yd (p)

slant height = 5 yd (s)

; sub it into the formula

surface area  = 9 + [tex]\frac{1}{2}[/tex] x 12 x 5

surface area = 39 yd

Answer:

The answer is A)  y =3x + 3

Answer:

3. 31

4. 6

5. 7

6. No  because the frequency table shows only ranges of times.

Step-by-step explanation:

3. Add up the number of students in each section of your table:

6 + 2 + 8 + 6 + 9 = 31

4. Only the first group ran under 9 minutes.

5. 8 students ran 1 mile in under 10 minutes (the first two sections)

15 students took 11 or more minutes to run 1 mile (the last 2 sections)

15 - 8 = 7

6. No, because the frequency table shows only ranges of times.

There are 31 students in PE class, 6 students ran 1 mile in under 9​ minutes, 8 students are there who ran 1 mile in under 10 minutes than students who took 11 or more minutes to run that​ distance and no student ran a mile in exactly 12​ minutes.

A branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data

A frequency distribution table is a method to organize the data given so that it makes it more meaningful and easier to understand.

The given frequency table

Time                  Number of students

8:00-8:59                     6

​9:00-9:59                     2

​10:00-10:59                  8

​11:00-11:59                    6

​12:00-12:59                  9

3. The number of students in the PE class

6+2+8+6+9

=31

4. Only the first group ran under 9 minutes which is 6 students

5.  8 students ran 1 mile in under 10 minutes

6+2=8

15 students took 11 or more minutes to run 1 mile

15 - 8 = 7

6. No, because the frequency table shows only ranges of times.

Hence there are 31 students in PE class, 6 students ran 1 mile in under 9​ minutes, 8 students are there who ran 1 mile in under 10 minutes than students who took 11 or more minutes to run that​ distance and no student ran a mile in exactly 12​ minutes.

Answer:

A

Step-by-step explanation:

A: -a/-b=c (negative number divided by negative number is positive number A is correct)

B: -a x b =c (negative number times positive number is become a negative number so correct answer is -c B is wrong)

C: -a/b=c (negative number divided by positive number is become a negative number so correct answer is -c C is wrong)

D: -a x -b=-c (negative number times negative number is become a positive number so correct answer is c D is also wrong)

Answer:

83

Step-by-step explanation:

its a guess bc its a right triangle and right triangle is 90 degrees minus 7 is 83

Answer:

I think it is 93 degrees

Step-by-step explanation:

A triangle has a full angle of 180 degrees

47+47 = 94

180-94=86

x-7=86

x = 93

Answer: ∠1 and ∠5

Step-by-step explanation:

You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.
