Exactly one solution
Answer:
Solution: There is exactly one solution, the lines intercept at one point, they are not the same line, so they do not have infinite solutions, and if they were to not intercept, they would have no solution.

A drawer contains unmatched socks. There are 7 black, 4 blue, and 5 white. What is the probability that you will select a white sock, not replace it, and then draw another white sock without looking?
0.10=10%
0.098=9.8%
0.078=7.8%
0.08.=8.3%
Answers
The probability that you will select a white sock, not replace it, and then draw another white sock without looking is 2/21
What probability?This is the likelihood or chance that an event will occur
Pr = Expecte/Total outcome
If there are 7 black, 4 blue, and 5 white in the drawer, the total outcome will be 15 socks
Pr(white socks) = 5/15 = 1/3
Pr(picking another) = 4/14 = 2/7
Pr(picking both socks) = 1/3 * 2/7
Pr(picking both socks) = 2/21
Hence the probability that you will select a white sock, not replace it, and then draw another white sock without looking is 2/21

10) Alex bought 2 apples and 4 pears that cost $3 each. Next, he bought a loaf of bread for $6. Write an expression that describes how much money Alex spent, and solve. please hurry tryna finish!!
Answers
Answer:
T = a(c) + p(c) + b(c)
T = $24
Step-by-step explanation:
This equation would represent the total amount of money Alex spent. By using this equation and plugging in the individual cost of each item and how many of each item he bought, we can calculate the total cost.
T = total cost
a = # of apples
p = # of pears
b = # of bread
c = cost of each item
When you plug in the individual cost of each item and how many of each item he bought, the equation should look like:
T = 2(3) + 4(3) + 1(6)
Then using these numbers, calculate the total cost:
T = $24

In February of 2006, there was a
record snowfall of 26.9 inches in one
day in New York City. The normal
snowfall for the month of February in
New York City is 8.5 inches and March
is 5.1 inches. How much more snow
fell in the one day storm in 2006 than
normally falls in February and March
combined
Answers
Answer:
40.5 inches
Step-by-step explanation:
I’m not sure if this is correct or not but my thinking is that you just add 26.9, 8.5, and 5.1 together since it says “How much more snow fell in the one day storm in 2006 than normal falls in February and March combined?” And combined basically means all together.
Answer: 13.3 more inches of snow fell in one day storm than normally falls in February and March combined.
February and March combined: 8.5+5.1 = 13.6
Since the question asked how much more, that means you subtract:
26.9 - 13.6 = 13.3

Answers
Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A

Choice C: a circle graph titled social media usage, with four sections labeled tweeter 17 percent, vidtok 48 percent, headbook 25 percent, and picturegram 10 percent
ChoiceD: a circle graph titled social media usage, with four sections labeled picturegram 17 percent, tweeter 48 percent, vidtok 25 percent, and headbook 10 percent
Answers
Answer:
The answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Step-by-step explanation:
By adding all the numbers you get 500, but you need to make it 100% so you divide the total number by five. To know what percent out of 100 you need to divide all of the variables by 5.
85 ÷ 5 = 172
40 ÷ 5 = 48
125 ÷ 5 = 25
50 ÷ 5 = 10
Thus the answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent

What is the surface area of the figure? PLEASE HELP ASAP !! 7th grade Geometry
Answers
Answer:
SA = 578ft²
Step-by-step explanation:
First, we have to know the formula of finding the surface area of a rectangular prism.
Formula: 2(wl + hl + hw)
w = width l = length h = height
Next, we separate the composite figure into two rectangular prisms.
Since we have all measurements, let's use that to find the SA.
The first shape (to the left)
SA = 2(wl + hl + hw)
SA = 2(4 x 9 + 9 x 9 + 9 x 4)
SA = 2(36 + 81 + 36)
SA = 2(153)
SA = 306
Then, we do the other shape(to the right)
We know the measurement of length = 4 because it is the same measurement as the width
SA = 2(wl + hl + hw)
SA = 2(4 x 4 + 15 x 4 + 15 x 4)
SA = 2(16 + 60 + 60)
SA = 2(136)
SA = 272
Lastly, we add those two
306 + 272 = 578
Therefore, SA = 578ft²
