Answer:

Step-by-step explanation:

sin A = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{6}{10}[/tex] = [tex]\frac{3}{5}[/tex]

cos A = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{8}{10}[/tex] = [tex]\frac{4}{5}[/tex]

tan F = [tex]\frac{DE}{FE}[/tex] = [tex]\frac{24}{18}[/tex] = [tex]\frac{4}{3}[/tex]

tan D = [tex]\frac{FE}{DE}[/tex] = [tex]\frac{18}{24}[/tex] = [tex]\frac{3}{4}[/tex]

sin D = [tex]\frac{FE}{FD}[/tex] = [tex]\frac{18}{30}[/tex] = [tex]\frac{3}{5}[/tex]

Answer:

Step-by-step equation:

15% of 60 is nine.

Percentage is equivalent to the portion of a quantity present in the whole. The portion of each person’s tip amount shared by Sara and 3 of her friends is $2.65.

A percentage is a value that indicates 100th part of any quantity.

To convert percentage into a fraction it is divided by 100.

Given that,

The amount of tip is 15% of the total amount A.

The total amount of 4 lunches = $60.

As per the question, the total amount can be written as,

15% of A = A - 60

=> 15 / 100 × A = A - 60  

=> A - (3 / 20) × A = 60

=> A - (3 / 20) × A = 60

=> (17 / 20) × A = 60

=> A = (60 × 20) / 17

=> A = 70.58

Now, the total amount of tip is,

15% of 70.58

(15 / 100) × 70.58 = 10.58

The tip shared by each friend = 10.58 ÷ 4

                                                 = 2.65

Hence, the portion of each person’s tip amount is $2.65.

Answer:

x=−3

Step-by-step explanation:

2(6x+1)−4(x−5)=−2

Step 1: Simplify both sides of the equation.

2(6x+1)−4(x−5)=−2

(2)(6x)+(2)(1)+(−4)(x)+(−4)(−5)=−2(Distribute)

12x+2+−4x+20=−2

(12x+−4x)+(2+20)=−2(Combine Like Terms)

8x+22=−2

8x+22=−2

Step 2: Subtract 22 from both sides.

8x+22−22=−2−22

8x=−24

Step 3: Divide both sides by 8.

8x/8=−24/8

the answer is x=18

Answer:

C. 2x + 12

Step-by-step explanation:

2(10) + 2(x-4)

= 20 + 2x - 8

= 2x + 20 - 8

= 2x + 12

Answer: 250 im not sure if its correct though

Step-by-step explanation: 8% = 8/100  

8 /100  × x = 20

Multiplying both sides by 100 and dividing both sides by 8,

we have x = 20 ×  100 /8

x = 250

If you are using a calculator, simply enter 20×100÷8, which will give you the answer.

Answer:

Angle S is 28 degrees.

Step-by-step explanation:

You know angle R is 62 degrees and that angle Q is 90 degrees because the angle is marked by a teeny square (as I like to call it). You ten can add these two angles together and you will get the angle of 152 degrees. And as you should know that all angles of a triangle added together are  180 degrees you just take 180 degrees and subtract it with the two known angles added together. Thus you know that the final answer to S is 28 degrees.

Answer:

Answer:

BOC is 80 and COD is 60

Step-by-step explanation:

If DOF is 120 you subtract 40 from it because of of AOB then COD is the remaining of 180

Answer:

52 sq mm

Step-by-step explanation:

you can break it into a long rectangle in the middle with dimensions of 2(6+8) or 2(14) = 28 sq mm

the triangle on the bottom has a base of (8-4) x height of 3, which gives 6 sq mm (you have to divide by 2)

the upper left rectangle is 6 x 3 = 18 sq mm

add: 28 + 6 + 18 = 52

Answer:

116 degrees

Step-by-step explanation:

well from the picture we know this is a 45 45 90 style triangle therefore in if CBE is equal to 32 then ECB should also be equal to 32 leaving you with a total number of 64 degrees within the triangle. and in every triangle you must add up the degrees to 180 so if we subtract 64 from 180 we get 116 degrees for BEC

Answer: 116

Step-by-step explanation:

32 + 32 (because the angles are complementary) + 116 = 180!

Answer:

4000π cm^2

Step-by-step explanation:

first we change the 1.6m to cm:

1.6m = 160cm

Now we can use the formula:

V = πr^2h

where π is just π, r is the radius (not the diameter) and h is the height

V = π * 5^2 * 160 = 4000π cm

Answer:

Step-by-step explanation:

[tex]\text{They give you the equation for the volume.}\\ \\ V=\pi r^2h\\ \\ \text{You simply need to plug in the values given to you for r and h.}\\ \\ r=10/2=5cm,\ h=1.6m(100cm/m)=160cm\\ \\

V=\pi 5^2(160)\\ \\ V=160(25)\pi\\ \\ V=4000\pi cm^3\\ \\ V\approx 12566.37 cm^3[/tex]

Answer:

25w+140=290

He will have enough money in 6 weeks

w represents the amount of weeks

Step-by-step explanation:

25w+140=290

$25 every week + the original $140 = the total needed $290

Answer:

140 + 25w = 290

w = 6

Step-by-step explanation:

Goal: $290

Currently have $140

Saving $25 each week (variable)

Start with your given amounts :

(base) 140 + 25w (variable solving for) = 290 (goal you want equation to equal)

w stands for the amount of weeks for the goal to be reached

Solve:

140 + 25w = 290

subtract 140

25w = 150

divide 25

w=6

Double check (optional but suggested)

140 + 25 (6) = 290

140 + 150 = 290

290 = 290
