Which equation can we use to find the length of the side labeled x?
What is the value of x?

Answers

Answer 1

Answer:

Answer:

option d

d ---- sin30 =5/x

Answer 2

Answer:

Answer:

D. sin 30° = 5/x

Step-by-step explanation:

recall that for a right triange, considering one of the acute angles θ

sin θ = length of opposite side / length of hypotenuse

from the picture, we can see that

θ = 30°, length of opposite site = 5 and length of hypotenuse = x

substituting this into the above equation

sin 30° = 5/x

The number -2 is a solution to which of the following inequalities? -3x < 1
x - 7 < -4
-12/x> 10
x + 7 > 5

Answers

Substitute the value of x = -2 to the inequalities:

-3x < 1

(-3)(-2) < 1

6 < 1 FALSE

x - 7 < -4

-2 - 7 < -4

-9 < -4 TRUE

-12/x > 10

-12/(-2) > 10

6 > 10 FALSE

x + 7 > 5

-2 + 7 > 5

5 > 5 FALSE

Answer: x - 7 < -4

Step-by-step explanation:

x - 7 < -4, plug in the -2.

-2 - 7< -4, simplify; -2+-7=-9

=- 9<-4

During the first hour of operation the farm stand owner sold 15% of the apples he had. On the second hour he sold 20% of the remaining apples. On the third hour he sold 25% of the remaining apples, and so on, selling 5% more each following hour. If during the third hour he sold 34 kg of apples, how many kilograms of apples did he have initially?

Answers

Answer:

75 kg

Step-by-step explanation:

%25 of ___ will give you 34.

____ x 0.20 = 34

____ = 34/0.20

34/0.20=170

___=170

Harper has $15.00 to spend at the grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers that costs $3.50. Write and solve an inequality that models this situation and could be used to determine the maximum number of bags of fruit, b, Harper can buy.

Answers

Answer:

4.75x + 3.75y ≤ 15 inequality models the given situation.

Harper can buy at maximum 3 bags of fruits.

Step-by-step explanation:

Given : Harper has $15.00 to spend at the grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers that costs $3.50.

We have to write and solve an inequality that models this situation and could be used to determine the maximum number of bags of fruit that Harper can buy.

Let Harper buys 'x' bags of fruit

and 'y' box of crackers

Given : cost of one bags of fruits is $ 4.75

so the cost of x bags of fruits is 4.75x

Given : cost of one box of cracker is $ 3.50

so the cost of y box of crackers is 3.75y

also, Harper has $15.00 to spend at the grocery store

So the maximum amount he can spend is $15

So inequality become,

4.75x + 3.75y ≤ 15

So the maximum number of bags of fruit Harper can buy.

is when he buys no box of cracker.

Put y = 0 in above inequality , we have,

4.75x + 3.75(0) ≤ 15

4.75x ≤ 15

Divide both side by 4.75

We have , x = 3.158 ≈ 3

So , Harper can buy at maximum 3 bags of fruits.

since harper has only %15 that is the most she can spend, therefore we would have 15> or = 4.75b+3.5c. the best way to solve this would be to divide 15 by 4.75, then round down to the nearest whole number. if you do this, you get 3 bags of fruit.
