Answer:

The given lines are un-related.

Step-by-step explanation:

In the question two functions are given as h(t)=3t-4 and j(t)=5-t.

It is required to find whether these lines are perpendicular, parallel or neither.

Step 1 of 1

Find the slope of two lines by comparing these to the standard form.

y=mx+b

Then, $m_{1}=3

And $m_{2}=-1

Since, both slopes are neither equal nor reciprocal of each other.

Therefore, the lines are un-related.

What are the missing angle measures in triangle ABC?
Finger [1]

we know that

In the right triangle ABC

∠A+∠B=90 ------> by complementary angles

so

Step 1

Find the measure of angle B

we know that

tan\  B=\frac{opposite\  side\  angle\  B}{adjacent\  side\  angle\  B}

in this problem

opposite\  side\  angle\  B=7in\\ adjacent\  side\  angle\  B=5in

so

tan\  B=\frac{7}{5} \\ \\ B=arc\ tan\frac{7}{5} \\ \\ B=54.5\ degrees

Step 2

Find the measure of angle A

A+B=90\\ A=90-B\\ A=90-54.5\\ A=35.5\ degrees

therefore

the answer is the option

35.5° and 54.5°

you go to a grocery store and buy a $2.50 bag of sugar and a sandwich for $1.75. The sales tax for your state is 7%. What is the
Rashid [163]

Answer: My guess is $4.55


Step-by-step explanation:

2.50 + 1.75 = 4.25 (This is the total of everything you bought)

4.25 x 0.07= 0.2975 (0.2975 is 7% of 4.25 but because this is money I will round it to <em>0.30</em>)

(0.30 is the tax so now add it to the original amount)

$4.25 + $0.30 = $4.55
