What is the value of a?

Answer:

option 4

Step-by-step explanation:

|a| represents Absolute value, it is the distance from zero that a number is on the number line. And we know distance cannot be negative.

So,

[tex]|a| = a[/tex]

[tex]|-a| = a\\\\| \frac{-a}{b}| = \frac{a}{b}\\\\|\frac{a}{-b}| = \frac{a}{b}[/tex]

Answer:

55%

Step-by-step explanation:

For percentages, you need to divide the part by the whole, then multiply by 100.

In this case, [tex]\frac{22}{40}[/tex] = 0.55.

Then multiply by 100 to get a percentage: 0.55 x 100 = 55%

Answer:

55%

Step-by-step explanation:

Total number of movies= 40

Number of movies rated very good= 22

Percentage of movies rated very good= 22/40*100%

                                                                = 55%

Answer:

(42,48)?

Step-by-step explanation:

Answer:

(42, 27)

Step-by-step explanation:

The first rule is to do [tex]48-6[/tex], so this would be the x- axis.

The second rule is to do [tex]30-3[/tex], so this would be the y-axis.

The first ordered pair would be (48, 30), then the second ordered pair would be (42, 27).

Answer:

12x + 8 = 12 x 6 + 8 = 80

8x-3 = 8 x 6 - 3 = 44

Step-by-step explanation:

(12x+8) + 55 + (8x-3) = 180 (Angle Sum Property)

(8+55-3) + (12x + 8x) = 180( group the variables)

(60) + (20x) = 180

20x = 180 - 60

20x = 120

x = 120/20 = 6

x=6

Answer:

80/7 simplified its 11 3/7

Step-by-step explanation:

lmk if you need an explanation! :]

60/9 ÷ 12/7

67 ÷ 21/ 63

= 0.0506

11 3/7

Answer:

Talwar has 35% chance of getting cured

Answer:

C. 3x + x = 67

Step-by-step explanation:

Means Mathew has 3 units and Daniel has 1 unit.

There's 4 units in total.

4x = 67

3x + x = 67

3x is Mathew's DVDs

x is Daniel's DVDs

Step-by-step explanation:

cot < B = BC/AC = 7/24

_____

Answer:

First Question = 16 Second Question = 8

Step-by-step explanation:

First one

32+48=x(2+3)

80=5x

Divide each sides with 5 and you have x=16

Second one

32+48=4(x+12)

80=4x+48

subtract 48 from 48 and 80 and you have 32=4x.

Divide it with 4 both side and you have x=8

Answer:

42%

Step-by-step explanation:

I think it's 42% because out of the 57 girls 34 prefer biology,20 prefer chemistry then it means the remaining 3 prefer physics. There's 43 boys, 8 prefer chemistry,27 prefer physics which leaves us with 8 boys who maybe prefer biology. Therefore:

(34+8)÷100×100 = 42%

Answer:

Answer:

18

Step-by-step explanation:

[tex]\frac{-72}{-4} = 18[/tex]

Answer:

[tex]18[/tex]

Step-by-step explanation:

We know that

[tex]( - ) \div ( - ) = ( + )[/tex]

So,

[tex]( - 72) \div ( - 4) = 18[/tex]

Answer:

-0.3

Step-by-step explanation:

Answer:

-0,3

Step-by-step explanation:

Answer: Adjacent

Step-by-step explanation:

Complementary means angles summing upto 90°

Vertical means opposite angles

Supplementary means angles summing upto 180°

So, the resonable answer will be adjacent since both the angles are beside each other.

Step-by-step explanation:

==========================================================

Explanation:

At first the car isn't moving at all. This is at time 0. So this means the graph starts at the origin (0,0). Based on this alone, the answer is either choice B or choice C.

We can rule out choice C because the rates of change won't be constant to give those sharp straight lines. Instead, we have a gradual shift in speeds as the roller coaster progresses. So we'll have more of a curved shape as choice B shows.

Note that each time the car is going downhill, the speed goes up. On the flip side, as the car goes uphill, the speed goes down. So the direction of movement runs counter to the speed graph direction (one goes up, the other goes down).

Answer:

10 miles

Step-by-step explanation:

35/7 is 5 so therefore if you do 5+5+5+5+5+5+5 is 35

so that means 2 gallons which is 10

Since ∠AD are 180°, and each side is the same,

180°-30°-50°=100°

Answer:

8 = x

or

x = 8

Step-by-step explanation:

x – 3 = 5

x + -3 + 3 = 5 + 3

x = 5 + 3

(5 + 3 = 8)

x = 8

Answer:

x=8

Step-by-step explanation:

x-3=5

x-3+3=5+3

x=8

Answer:

t = 5

Step-by-step explanation:

by using guess and check, we can plug in the numbers 5 into t, 3 into s, and 10 into r.

if t = 5, then r must mean twice that number meaning it is 10.

the remainder would be s which means it is 3.

r+s=13 into 10 + 3 = 13

2t+s=13 into 2(5) + 3 = 13

Answer:

Volume: 864

Surface Area: 684

Step-by-step explanation:

Volume:

[tex]\frac{1}{2}(9 * 16 * 12) = 864[/tex]

Surface-Area: (Pretty Self-explanatory)

1. Triangles - 12 * 9 = 108 (You don't need to divide it by two, just leave it as is because there are two of these triangles.)

2. Base - 16 * 9 = 144

3. Height/Base - 12 * 16 = 192

4. 15 * 16 = 240

192 + 144 + 108 + 240 = 444

The Surface Area is 684.
