Answer:
p = 23
q = 18
Step-by-step explanation:
The four interior angles of a square are all 90° each
4p - 2 = 90
⇒ 4p = 92
⇒ p = 92 ÷ 4
⇒ p = 23
5q = 90
⇒ q = 90 ÷ 5
⇒ q = 18
Answer:
p=23; q=18.
Step-by-step explanation:
1) m∠(XWZ)=90, then 4p-2=90 and p=23°;
2) m∠(WZY)=90, then 5q=90 and q=18°.

Answers
Solution:
18-7s=-9s to -7s=-9s-18 (change the sign of the constant [18] and then move it to the right)
Now move the variable (-9s) to the left side and change its sign as well (now it's just +9s)
Now we have -7s + 9s= -18
Combine the like terms (-7s+9s)
Now we have 2s= -18
And then divide both sides of the equation by two (which equals s = -9)
And then you have your answer, s = -9
Hope you have a great day, God bless! :)

A = 84
The rectangle is 18 ft by 12 ft, which leads to an area of 18*12 = 216 sq ft.

Alexa is researching a cure for the coronavirus. She needs 14 test tubes for 4 experiments. The first experiment requires 2 test tubes, and the remainder of the tubes are used evenly over the rest of the experiments. How many test tubes did she use for the last experiment?
Answers
Answer:
She used 4 test tubes for the last experiment
Step-by-step explanation:
Total test tubes needed = 14
Experiment 1 = 2 test tubes
Total test tubes remaining = total - used
= 14 - 2
= 12 test tubes
Remaining experiment = 4 - 1
= 3
Test tubes used for the remaining experiment = test tubes remaining / Experiment remaining
= 12 / 3
= 4 test tubes
How many test tubes did she use for the last experiment?
She used 4 test tubes for the last experiment
A parabola can be drawn given a focus of (-9, -7) and a directrix of x = 9. Write

Check the picture below, so the parabola looks more or less like so, with a vertex at (0 , -7), let's recall the vertex is half-way between the focus point and the directrix.

please help quick!! Jane makes house calls. For each, she is paid a base amount and makes additional money for each hour she works. The graph below shows her pay (in dollars) versus the number of hours worked.
Answers
Answer: a) $30 b) $50 c) $20 each hour d) No, because the line does not pass through (0,0)
Step-by-step explanation:
What is Jane's pay if she doesn't work any hours? This question means how much money does Jane gets paid for working 0 hours (y-intercept). At 0 hours on the x-axis, the point on the line is $30. This can be written as (0,30)
If she works 1 hour, the point where 1 hour on the x-axis meets with the y-axis is $50 dollars. This can be written as (1,50).
Her pay increase each hour is the slope in this given equation as the starting payment before completing any hours work is $30 and the line increases at a positive rate of change. The slope is y^2-y^1 divided by x^2-x^1, and we have (0,30) and (1,50). Plugging them into the formula, 50-30 divided by 1-0 is 20; the slope is $20 for every 1-hour increase).
And for determining whether b and c are equal, every answer choice includes whether the line passes through the point (0,0). After answering problem c, you should find that your equation is y=20x+30 (20 as the slope and 30 as the y-intercept). As a reminder, b is $50 and c is $20, so you already know it is not the top two answer choices. So to see if it DOES pass through (0,0) you can plug the values into the equation OR graph it. Either way, you will see that (0,0) does not pass through the line and that 0 does not equal 30 (0=20(0)+30).

Answers
Answer:
d₃ = 803.9 Miles
Step-by-step explanation:
d₁ = 560 Miles
R₁ = N35⁰E
d₂ = 410 Miles
R₂ = S76⁰E
d₃ = ?
α = 35⁰+76⁰ = 111⁰
We can apply the Law of Cosines as follows
d₃ = √(d₁² + d₂² - 2*d₁*d₂* Cos α)
⇒ d₃ = √(560² + 410² - 2*560*410* Cos 111⁰) = 803.9 Miles

Hannah works at Blooming Bouquets flower shop. She uses 2 roses for every 5 carnations in the Spring Medley bouquets. Today she will make a Spring Medley bouquet with 16 roses.
How many carnations should Hannah use in the bouquet?
Answers
Answer:
40 carnations
Step-by-step explanation:
Using the principle of proportional relationship, the number of carnations to be used in the bouquet is 40
Setting up the proportional relationship thus :
2 roses = 5 carnations ----(1)
16 roses = P carnations - - - - - 2)
Solve for p :
Cross multiply :
2p = 16 × 5
2p = 80
p = 80 /2
p = 40
Therefore, the Number of carnations to be used is 40
