A = 14°

Step-by-step explanation:

We can use sine law in this situation, where

where a and b are the lengths of the sides opposite the corresponding angles. From the given diagram, we can see that

[tex]\dfrac{\sin A}{7\:\text{yd}} = \dfrac{\sin 75°}{28\:\text{yd}}[/tex]

or

[tex]\sin A = \dfrac{7}{28}\sin 75° = 0.241[/tex]

lisa's father gave her $1032 to buy a present. this covered 3/5 of the cost. How many did the present cost?

Answers

Answer:

$1720

Step-by-step explanation:

1032 is 3/5 of the cost.

Divide 1032 by 3/5, which is 1720.

Thus, the answer is $1720.

The cost of the present day will be $1,720.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Lisa's father gave her $1032 to buy a present. This covered 3/5 of the cost.

The cost of the present day will be given by the division of the numbers 1032 and 3/5.

⇒ 1032 / (3/5)

⇒ 1032 x 5 / 3

⇒ $1,720

The cost of the present day will be $1,720.

does 17/10 and 12/5 form a proportion?

Answers

Answer:

No

Step-by-step explanation:

17/10 is not proportional to 12/5. Proportional relationships are relationships between two variables where their ratios are equivalent.  17/10 as a ratio is 17:10 and 12/5 as a ratio would be 12:5. A proportional relationship for 12/5 would be 24/10.

Hope this helps :)

No, 17/10 and 12/5 do not form a proportion.

What is a proportion?

A proportion is an equation that sets two ratios at the same value.

We have two fractions,

17/10 and 12/5.

That means,

17/10 = 1.7

And 12/5 = 2.4

And 1.7 is not equals to 2.4.

So, the fraction does not show the proportional relationship.

Therefore,  the fraction does not show the proportional relationship.

There are 25 students in a class, and 6 of them will be chosen to go on a field
trip. How many ways can these students be chosen?

Answers

Answer: 150 ways.

Explanation: This question deals with a combination. To find the total number of ways these students may be arranged in a field trip, assuming that the combination does not repeat (there can only be one of each student in a given group of 6), one must simply multiply the number of students total, 25, by the number of students allowed in a group, which is 6. Therefore, 25 • 6 = 150, which gives us our answer.

Pizza Palace sells cheese pepperoni, sausage and mushroom pizzas. Caleb noticed that for every 10 orders of cheese pizza, there were 7 orders of pepperoni pizza, 5 orders of sausage pizza and 8 orders of mushrooms pizza. If there were 35 pepperoni pizzas ordered, how many total pizzas were ordered?

Answers

Step-by-step explanation:

cheese : pepperoni : sausage : mushroom =

10 : 7 : 5 : 8

so, in total there are 10+7+5+8 = 30 "business pieces".

to get the total number of pizzas, we need to see how many pizzas are sold per "business piece" ?

we get this from the 35 orders of pepperoni pizzas.

these 35 orders represent 7 "business pieces".

that means 1 "business piece" = 35/7 = 5 pizzas.

that means that 30 "business pieces" are 5×30 = 150

so, in total, 150 pizzas were ordered.

Answers

Answer:

m < -175/k

f = -11 + [tex]\frac{3}{5}[/tex]c

Step-by-step explanation:

Part A:

-mk - 90 > 85

add 90 to each side to get:

-mk > 175

divide each side by -k to get:

m < -175/k

(inequality symbol switched because we divided by a negative)

Part B:

3c - 5f = 55

subtract 3c from each side to get:

-5f = 55 - 3c

divide each side by -5 to get:

f = -(55 - 3c) / 5  or -11 + [tex]\frac{3}{5}[/tex]c
