Answer:

81 un²

Step-by-step explanation:

9 · 7 = 63 un²

(b · h) ÷ 2

(5 · 4) ÷ 2 = 10 un²

(4 · 4) ÷ 2 = 8 un²

8 un² + 10 un² + 63 un²

81 un²

Answer:

81 un^2

Step-by-step explanation:

Find area of the rectangle. 9 x 7 = 63

Find area of the triangle. 9 x 4 = 36/2=18

63 + 18 = 81

Answer:

see below

Step-by-step explanation:

w = x+y/z

Subtract x from each side

w-x = x+y/z -x

w-x = y/z

Multiply each side by z

(w-x) *z = y/z*z

(w-x) *z = y

You can distribute the z if desired

wz -xz = y

Answer:

y = z(w - x)

Step-by-step explanation:

w = x + y/z

Subtract x from both sides

w - x = y/z

Multiply both sides by z

z(w - x) = y

Flip

y = z(w - x)

Answer:

what's the problem

Step-by-step explanation:

.............

The diver will be in the air for approximately 0.78 seconds to the nearest hundredth of a second.

The equation that represents the height of the diver above the surface of the pool is given by:

h(t) = -16t² + 6t + 33

where t is the time in seconds and h(t) is the height of the diver above the surface of the pool in feet.

The diver will be in the air until he reaches the surface of the pool, which means that his height will be 0. Therefore, we can set h(t) equal to 0 and solve for t:

-16t² + 6t + 33 = 0

We can use the quadratic formula to solve for t:

t = (-b ± sqrt(b² - 4ac)) / 2a

where a = -16, b = 6, and c = 33.

Plugging in these values, we get:

t = (-6 ± sqrt(6² - 4(-16)(33))) / 2(-16)

t = (-6 ± sqrt(36 + 2112)) / (-32)

t = (-6 ± sqrt(2148)) / (-32)

Simplifying:

t = (-6 ± 46.34) / (-32)

So we have two solutions:

t = (-6 + 46.34) / (-32) ≈ 0.78 seconds

t = (-6 - 46.34) / (-32) ≈ 2.64 seconds

Since the diver cannot be in the air for a negative amount of time, we reject the second solution.

Answer:

If the correction of 6 * 6X is accurate then I hope this is the answer.

Step-by-step explanation:

6(6x)+3x=3+3x+5

1. First multiply 6 by 6

36x+3x=3+3x+5

2. Then add 36X and 3X

39x=3+3x+5

3. After that add 3 and 5

39x=3x+8

4. Subtract 3x from both sides of the equation.

39x−3x=8

5. Subtract 3x from 39x

36x=8

Answer:

2.03 liters of 30% antifreeze should be drained and replaced with 100% antifreeze to get the desired strength.

Step-by-step explanation:

Since a car radiator needs a 40% antifreeze solution, and the radiator now holds 14 liters of a 30% solution, to determine how many liters of this should be drained and replaced with 100% antifreeze to get the desired strength the following calculation must be performed:

100 x 0.3 + 0 x 1 = 30

90 x 0.3 + 10 x 1 = 37

85 x 0.3 + 15 x 1 = 40.5

86 x 0.3 + 14 x 1 = 39.8

85.8 x 0.3 + 14.2 x 1 = 39.94

85.7 x 0.3 + 14.3 x 1 = 40.01

85.71 x 0.3 + 14.29 x 1 = 40

100 = 14

14.29 = X

14.29 x 14/100 = X

200.06 / 100 = X

2.03 = X

Therefore, 2.03 liters of 30% antifreeze should be drained and replaced with 100% antifreeze to get the desired strength.

Step-by-step explanation:

3/6 * 3/6 = 1/2 * 1/2 = 1/4

The probability of rolling an even number on the first roll and an odd number on the second roll is equal to 1/4.

We have given that,

A single six-sided die is rolled twice.

We have to determine,

The probability of rolling an even number on the first roll and an odd number on the second roll.

The probability is the ratio of the number of favorable outcomes to the total outcomes in that sample space. It is expressed as, Probability of an event P(E) = (Number of favorable outcomes) ÷ (Sample space).

Therefore the,

Probability of rolling an even number on the first roll and an odd number on the second roll

= 3/6 * 3/6

= 1/2 * 1/2

= 1/4

The probability of rolling an even number on the first roll and an odd number on the second roll is equal to 1/4.
