What is the measure of ∠DBA?

Answer:

Step-by-step explanation:

Equation

5y = 3y + 4

combine like terms 3y becomes negative when moved to the left side being that its positive on the right. 4 has no variable so it stands alone on the right side.

-3y + 5y = 4

After adding a low negative to a high positive number. Turns into 2y.

2y = 4

Divide 2 on both sides to remove the number from the variable on the left.

[tex]\frac{2}{2}[/tex]y = [tex]\frac{4}{2}[/tex]

2 is canceled on the left side which gives the solution for Y.

y = 2

Answer:

x= 22.6

Step-by-step explanation:

This little red square means that is a right angle (90 degrees)  

x is the complementary of 67.4  (Both add to 90)

90-67.4 = 22.6

Answer:

82

Step-by-step explanation:

180-98

Answer:

X: 56°

Z: 180°

Y: 42°

Step-by-step explanation:

X is improved as 56°

To solve the "?", we have an expression:

(98° + 180°) - 180°

And that is 82°.

So Z is 180°.

To know what is Y, we have to subtract and add:

Y= 180° - (X + ?)

X is 56° and "?" is 82°

That would be 180° - (56° + 82°)

That would be 180° - 138°

Y is 42°

Answer:

C. 12 cm

Step-by-step explanation:

h = V ÷ (π × r²)

h = 500π cm³(π × 5²)

h = 12 cm

Answer:

5 and 6 look down.

7. 12%

8. 75/250 30%

Step-by-step explanation:

5. The spinner shown is not a fair spinner because sections 1 and 5 are bigger than the rest of the sections.

6. The cube is fair because you have a 1 in 6 chance of getting a number. There is not a greater chance to roll a 1 than a 4.

7. There are 3 marbles that are white out of 25. This means that the probability of getting a white marble is a 3/25 chance.

There is a 12 percent chance that you will pick a marble

8. In this problem you are doing the same thing as 7. 10/25 is 40% chance and 75/250 is 30% chance.

Answer:

Chance of green = 2/3

Chance of blue = 1/3

Chance of green then blue = 0.222...

Step-by-step explanation:

7-1=6; 4-1=3

6+3=9

Chance of green = 6/9 or 2/3

Chance of blue = 3/9 or 1/3

Chance of green then blue = 2/3 * 1/3 = 0.222...

Answer:

the MAD is 5.6 thousand

Step-by-step explanation:

First, find the mean: 41 + 38 + 36 + 57 + 43 = 215, divide it by the amount of numbers, 5, 215/5 = 43. Now that we have the mean, find the distance each number is away from it:

|41 - 43| = 2, |38 - 43| = 5, |36 - 43| = 7, |57 - 43| = 14, |43 - 43| = 0.

2 + 5 + 7 + 14 + 0 = 28, divide it by the amount of numbers to get 28/5 = 5.6

Answer:

The answer is C

Step-by-step explanation:

Think of p.e.m.d.a.s you do parenthesis first so

1. 4(2x-6)

2. 4*2x= 8x and 4*-6= -24

3. 8x-24 is your answer then you check the other side and oh wow its 8x-24

Answer:

1. x=5

2. x=3.18

3. x=1.1

4.x=7

5.x=4/5

Step-by-step explanation:

ok so basically what the question means is one number multiplied by another number is this number. for example the first one is 7 multiplied by x (x is a variable so it represents a number) equals 35. you just have to figure out what x equals. and in my opinion, the easiest way to do that is by dividing 35 and 7, which will give you 5. so basically the equation is just 7 x 5 = 35. hope this helps :)

Answer:

1. x = 5

2. x = 3.18181818

3. x = 1.1

4. x = 7

5. x = 0.8

Step-by-step explanation:

1. 35 = 7x now if we divide both sides by 7 we get

35/7 = x

5 = x

2. 35 = 11x divide  both sides by 11:

35/11 = x

3.1818181818 = x

3. 7x = 7.7 divide both sides by 7 again:

x = 7.7/7

x = 1.1

4. 0.3x = 2.1 divide by 0.3 on both sides

x = 2.1/0.3

x = 7

5. 2/5 = 1/2x first simplify: 2/5 = 0.4    1/2 = 0.5

0.4 = 0.5x divide both sides by 0.5:

0.4/0.5 = x

0.8 = x
