Answer:

The correct answer for this problem would be B

Step-by-step explanation:

The first thing I would do in this problem is see how much money he would make in a day. You would do this by doing,

28 x 8 = 224

Now that we know how much money he makes in a day, you should multiply $224 by 6 days to see if his estimate was correct or not.

224 x 6 = 1,344

With this we can conclude his estimate was close enough, since it was only $4 off.

Step-by-step explanation:

1/5x means x can be any varible plus 2, and 1/5 (x +2) means that you multiply 1/5 by x then add 2.

Answer:

No

because [tex]\frac{1}{5\\\\}[/tex]x +2 is not the same as [tex]\frac{1}{5\\}[/tex](x+2)

Answer:

down below.

Step-by-step explanation:

One–third of the product of −8 and 9 = -24

-8(9) = -72

-72 / 3 OR -72(1/3) = -24

Half the sum of 8 and −6 = 1

8 + (-6) =2

2 / 2 = 1

Three times the sum of 12 and −6 = 18

12 + (-6) = 6

6 * 3 = 18

One-fifth the product of 1 and −5 = -1

1(-5) = -5

-5/5 = -1

Five times the sum of −8 and 4 = -20

-8 + 4 = -4

-4 * 5 = -20

Answer 1: Meal

Answer 2: Spinning the number less than 3 and fliping tailes

Step-by-step explanation 1: Because there are way more choices to choose from so more people will go for the meal chose.

Step-by-step explanation 2: It is more likely to land on a 3 or below because of the chances and for it to land on heads is a 50-50 chance

Hope this helped!

Answer:

8 = 21    9 = 20   10 = 24   11 = 60

Step-by-step explanation:

15 = 7/10

16 = 9/10

17  = 9/10

18 = 0/10

19 = 13/10

20 = 13/10

AMOGUS

Answer:

Step-by-step explanation:

Formula to solve for avg./mean: x + y + z...(numbers given in problem). Divide the sum by the number of numbers.

10 + 12 + 8 + 11 + 10 + 15 + 7 = 73

73 / 7 = 10.428571...

73/7 ~ 10.43

Answer:

I think the answer 13232.

Step-by-step explanation:

I got this answer because times 30, 24, and 18 and you get 12960. Then you times one triangle 8 and 17 and you get 136. Next since there are 2 triangles you will add 136 and 136 together and you get 272. Finally you add 272 and 12960 you get 13232. Hope this is correct and it helps.

Answer:

acute angles... I think 35

Angle A: 56 degrees.

Angle B: 34 degrees.

Angle C: 56 degrees.

Angle D: 124 degrees.

Step-by-step explanation:

Angle A = 180-124, or 56 degrees.

The right angle given plus Angle B must equal 124, so 124-90 = 34 degrees.

Angle B = 34 degrees.

Angle C = 180-124, or 56.

Answer:

4 (rounded to the nearest whole number)

Step-by-step explanation:

total height = 3 x 2 = 6

Volume = radius^2 * pi * height

75.36= radius^2 * pi * 6

75.36/pi = radius^2 * 6  

23,987833 = radius^2 * 6

23,987833/6 = radius^2

3,997972 = radius^2

radius = 1,999493

diameter = radius x 2 = 1,999493 x 2 = 3,998986

Answer:

[tex]\sqrt{18.04}[/tex]

Step-by-step explanation:

The wording is a bit confusing, but i beleive it basically means that we're trying to find the length on a leg of a triangle with a leg length of 3 and a hypotenuse of 5.2

if we write this out as an equation, it gives us:

[tex]5.2^{2}-3^{2}[/tex]

If we then simplify this, we get 27.04 - 9, which then simplifies to 18.04.

We then need to get the square root of this number to get the answer, thus the answer is [tex]\sqrt{18.04}[/tex]

Answer:

1. a = 16

2. x = 4

3. x = 0

4. n = -20

Step-by-step explanation:

To check it, plug it back into the equations.

1.

6 = a/4 + 2

4 = a/4

16 = a

2.

-6 + x/4 = -5

x/4 = 1

x = 4

3.

9x - 7 = -7

9x = 0

x = 0

4.

0 = 4 + n/5

-4 = n/5

-20 = n

B.

I might be wrong pls dont be mad

Answer:

There are about 3 students that are left handed in a class. First Sara took the percentage of left handed people, 11%,  and multiplied it by the amount of students in the class, 30. She got 3.3 but you can't have 0.3 of a person so she rounded it down to 3.

Answer:

Her first step is stating that left-handed people represent 11% of 30 people, which results in 3 people.

Her steps and answer are correct.

Answer:

Step-by-step explanation:

First, simplify the equation they give you

125x+200≥1200 ---------> 125x≥1000---------->x≥8

So, x has to be greater than or equal to 8 which rules out b or d.

So the answers are narrowed down to a and c, the only difference is that the dot in A is filled in whereas the dot in c is not. In math, having a filled in circle means that value is included (≥ sign), so we will choose the answer a.

Step-by-step explanation:

4x+3x-5+2x+5=180 (to find x)

9x=180

x=20

Therefore DEF=AEC(vertically opposite angles are equal)

AEC=DEC

=4x +3x-5

=4(20)+3(20)-5

=135°
