In PQR the measure of R=90 the measure of P=62 and RP=8.6 find the length of QR to the nearest tenth of a foot.
Answers
Answer:
QR = 4.6 ft
Step-by-step explanation:
By applying tangent rule in the given triangle PQR,
tan(62°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{8.6}{QR}[/tex]
QR = [tex]\frac{8.6}{\text{tan}(62)}[/tex]
QR = 4.573
QR ≈ 4.6 ft

A shipping container will be used to transport several 140-kilogram crates across the
country by rail. The greatest weight that can be loaded into the container is 26000
kilograms. Other shipments weighing 13200 kilograms have already been loaded into
the container. Which inequality can be used to determine c, the greatest number of
140-kilogram crates that can be loaded onto the shipping container?
Answers
Answer:
91.42 crates
Step-by-step explanation:
Let
Greatest Number of 140kg crates = x
weight of crate = 140-kilogram
Weight of other shipment = 13200 kilograms
greatest weight of container = 26000 kilograms
Weight of other shipment + (weight of crate * number of crates) ≤ greatest weight of container
13,200 + 140x ≤ 26,000
140x ≤ 26,000 - 13,200
140x ≤ 12,800
x ≤ 12,800/140
x ≤ 91.42 kilograms
Greatest Number of 140kg crates = 91.42 crates
A caterer is preparing a dinner for a party. Shecharges an initial fee of $16 and $8.25 per person. How manypeople can attend a dinner that costs $131. 50? Write an equationand solve.
Answers
Answer:
The nomber of people can attend a dinner that costs $131. 50 is 14.
Step-by-step explanation:
With the information provided, it can be said that the total cost of a dinner would be equal to the initial fee plus the result of multiplying the price per person for the number of people, which can be expressed as:
c=16+8.25x, where:
c is the total cost of he dinner
x is the number of people
Now, you can replace c with 131.50 that is the cost of a dinner and solve for x to find the number of people that can attend:
131.50=16+8.25x
131.50-16=8.25x
115.50=8.25x
x=115.50/8.25
x=14
According to this, the answer is that the nomber of people can attend a dinner that costs $131.50 is 14.

At the local store, the cost of 1 pair of jeans is $24 and the cost of 3 pairs is $24 × 3 = $72. At the online store, the cost of 2 pairs of jeans is ($22 × 2) + $6 = $50 and the cost of 3 pairs is ($22 × 3) + $6 = $72.
Answers
Complete question :
Complete the tables to relate the numbers of pairs of jeans to the cost of the jeans at each store. Assume that Tim is placing a single order, and
ignore any taxes.
Answer:
$24, $72
$50
Step-by-step explanation:
From the table :
At local store :
2 pair of jeans cost $48
Cost of a pair :
Cost of 2 pairs / number of pairs
$48 / 2 = $24
Cost of 3 pairs :
Cost per pair * number of pairs :
$24 * 3 = $72
At online store :
Cost of Jean include a fixed fee of $6
Cost of one pair of Jean = $28
Actual cost of Jean :
$28 - $6 = $22
Hence, cost of 2 pair of jeans:
($22*2) + $6
$44 + $6 = $50

if f(x) = 2x -3 what is the value of f(x) when x is -5?
Answers
Answer:
-13
Step-by-step explanation:
To find the value of f(x) when x is -5, substitute -5 for the x in the equation. Then, simplify:
[tex]f(x) = 2x-3\\\\f(-5) = 2(-5)-3\\f(-5) = -10-3\\f(-5) = -13[/tex]
So, when x is -5, the value of f(x) will be -13.

Answers
Answer:
Total cost= $4,445.28
Step-by-step explanation:
Giving the following formula:
Each side of a square classroom is 8 yards long.
The new carpet costs $79.38 per square yard.
First, we need to calculate the total number of square yards needed:
Square yards of the classrom= 8*8= 56
Now, the total cost:
Total cost= total square yards*unitary cost
Total cost= 56*79.38
Total cost= $4,445.28

Answers
Answer:
6x + 102 = 1,140
Step-by-step explanation:
We're looking for the sum. The insurance cost 17 dollars per ticket, and there are 6 tickets, so we have to multiply. 17 times 6 is 102. Next, we subtract 102 from both sides. 6x = 1,038. Then, divide by 6. x = 173. So, one ticket costs 173. I don't know if the insurance is included, but if it is, then add 17 and you get 190.
