First Question:

Follow PEMDAS

Parentheses, Exponents, Multiplication or Division, Addition or Subtraction

3 ÷ [tex]\frac{1}{4}[/tex] × (12 + 2³)

= 3 ÷ [tex]\frac{1}{4}[/tex] × (12 + 8)

= 3 ÷ [tex]\frac{1}{4}[/tex] × (20)

= 3 × 4 × 20

= 12 × 20

= 240

Second Question:

change the mixed number into an improper fraction:

[tex]3\frac{2}{3}[/tex] = [tex]\frac{11}{3}[/tex]

= [tex]\frac{11}{3}[/tex] ÷ [tex]\frac{3}{4}[/tex]

= [tex]\frac{11}{3}[/tex] × [tex]\frac{4}{3}[/tex]

= [tex]\frac{44}{3}[/tex]

rounded to WHOLE number: 14 containers

Answer:

height = 8.5 feet

Step-by-step explanation:

Area of a triangle formula:

a=1/2bh

substitute what's given

93.5 = (1/2)22h

93.5=11h

divide both sides by 11 to isolate h

h=8.5 ft

The hypotenuse has different lengths. It’s always c2 and the longest triangle length of all the triangle.

Answer:

x=60, y= 60

x=100, y= 20

x=40, y=80

Step-by-step explanation:

Triangles add up to 180 degrees. The ones above added to 60 equal 180.

60+60+60=180

100+20+60=180

40+80+60=180

Hope this helps! :)

Answer:

Its A C and D

Step-by-step explanation:

Answer:

arc WVY = 250°

Step-by-step explanation:

The tangent- tangent angle YXW is half the difference of the intercepted arcs

[tex]\frac{1}{2}[/tex] ( WVY - WY) = 70

[tex]\frac{1}{2}[/tex] (10a - (4a + 10) ) = 70 ( multiply both sides by 2 )

10a - 4a - 10 = 140

6a - 10 = 140 ( add 10 to both sides )

6a = 150 ( divide both sides by 6 )

a = 25

Then

arc WVY = 10x = 10 × 25 = 250°

Answer:

5

Step-by-step explanation:

Vanilla ice cream = 3/5 x 25 = 15

Remaining = 25 - 15 = 10

Mint ice cream = 1/2 x 10 = 5

Remainder = 10 - 5 = 5 = vanilla

Answer:

f(x) = -3x + 6

Step-by-step explanation:

The general linear function is;

y = mx + b

it can also be written as (x , f(x))

f(x) = mx + b

where m is the slope and b is the y-intercept

so we have the points ;

(0,6) and (4,-6)

So we have;

for f(0) to be 6, it means that the y-intercept b is 6

This is because the value of x at the y-intercept is 0

So we have this as;

f(x) = mx + 6

Now, let’s substitute the other point so as to get m

For the other point;

x = 4 and f(x) = -6

that means;

-6 = 4m + 6

4m = -6-6

4m = -12

m = -12/4

m = -3

So we have the equation as;

f(x) = -3x + 6

Answer:

8i + 4

Step-by-step explanation:

Add/subtract like terms:

7 - 3

= 4

-4i - (-12i)

-4i + 12i

= 8i

Add these together:

8i + 4

So, the simplified expression is 8i + 4

Answer:

B

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then

cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{3}{c}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

c = 3[tex]\sqrt{2}[/tex]

Answer:

m<B: 36

Step-by-step explanation:

x + 2x + 6x + 18 = 180

9x + 18 = 180

9x = 162

x = 18

m<B:

2x

2(18)

36

Answer:

m<B=36°

Step-by-step explanation:

The sum of angles in a triangle add up to 180°.

That means the sum of m<A+m<B+m<C=180°

We're given that:

m<A=x°

m<B=(2x)°

m<C=(6x+18)°

we can substitute those values as m<A, m<B, and m<C

x+2x+6x+18=180

combine like terms

9x+18=180

subtract 18 from both sides

9x=162

divide by 9

x=18°

we found the value of x, but we're not done yet

The question asks to find m<B, which is 2x°

in that case, we can substitute our known value to find the measure of <B

m<B=2x°

m<B=2(18)°

m<B=36°

Answer:

11/16 pounds each

Step By Step Explanation:

Change the mixed fraction to improper fraction

2 3/4 = 11/4

Divide the answer by 4

11/4 ÷ 4 = 11/16

Each friend gets 11/16 pounds

Answer:

B is the answer

Step-by-step explanation:

Since there is already a 90 degree angle in the right triangle, the other two angles must add up to 90.

[tex]3x + 6 + 2x - 1 = 90[/tex]

[tex]5x + 5 = 90[/tex]

[tex]5x = 85[/tex]

[tex]x = 17[/tex]

Plug 17 into both to find the smaller angle

[tex]3(17) + 6 = 57[/tex]

[tex]2(17) - 1 = 33[/tex]

[tex]33 < 57[/tex]

So 33 is the answer or B

Answer:

We have to find the value of x.

We need to substitute with 3 because they measure the same.

Step-by-step explanation:

(x - 1)

x - 1 = 3

x - 1 + 1 = 3 + 1

x = 4

(x + 1)

x + 1 = 5

x + 1 - 1 = 5 - 1

x = 4

Both answers are the same which means that they are correct.

Answer:

they have the same batting record

Step-by-step explanation:

Batting record for each :

Neil :

9 /11 = 0.8181

Maggie :

18 /22 = 0.8181

From here we see that they both have the same proportion of hits :

Hence they have the same batting record
