Answer:
3,000 meters

If p(x) = 2x2 – 4x and q(x) = x – 3, what is (p circle q) (x)?
2x2 – 4x + 12
2x2 – 16x + 18
2x2 – 16x + 30
2x2 – 16x + 15
Answer:
2x^2 - 16x + 30
Step-by-step explanation:
Here, we want to get the composite function;
p•q(x)
All we have to do here is to replace the x value in p(x) by the totality of q(x)
we have this as ;
= 2(x-3)^2 - 4(x-3)
= 2(x^2 -6x + 9) - 4(x-3)
= 2x^2 -12x + 18 -4x + 12
= 2x^2 - 16x + 30

What is 7x2? Please help! I need it!
Answer:
7 x 2 is 14.
Step-by-step explanation:
Its the same thing as 7 plus 7.
The Multiplication of 7 and 2 results to 14.
What is Multiplication?The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the factors that are multiplied are referred to as the factors. Repeated addition of the same number is made easier by multiplying the numbers.
We have to multiply 7 x 2.
So, we can either add 7 two times as
= 7 + 7
= 14
or we can multiply it
= 7 x 2
= 14

Find Gh if ABG ~ CDG, GH is an altitude of ABG, GI is an altitude of CDG, BG =5, DG= 10, and GI=7
Answer:
a. 3.5
Step-by-step explanation:
Since ∆ABG is similar to ∆CDG, therefore, their corresponding side lengths are proportional to each other.
Therefore:
DG/BG = GI/GH
10/5 = 7/GH (substitution)
Cross multiply
GH*10 = 7*5
GH*10 = 35
Divide both sides by 10
GH = 35/10
GH = 3.5

A pet store sells cats for $50 and dogs for $100. In only one day it sells a total of 4 pets and makes $300, find out how many cats and dogs it sold by writing as a system of equations and graphing to solve it.
Answer:
$1,350
Step-by-step explanation:
. $50 = Cats
. $100 = Dogs
. Total of pets = 4
. $300 for 4 pets
100 + 50 = $150 = how many dogs and cats cost in all
4 x 300 = $1,200 = how many pets in all, not just dogs and cats costs
1,200 + 150 = $1,350

If 55 Canadian Dollar = 157 Qatari Riyal and 1 Qatari
Riyal = 30NC, how much Canadian Dollar is equal to Rs.2870?
Answer:
5cd=157qr
1cd=157/55qr
or
qr=55/157cd
Step-by-step explanation:
1qr=30nc
55/157×cd=30nc
55/157×1/30×cd=1nc
1nc=0.011670cd
rs2870=0.01167×2870cd=33.49cd
₹2870 is equal to 33.49 CD.
Given that, 55 Canadian Dollars=157 Qatari Riyal and 1 Qatari Riyal=30NC.
We need to find how much the Canadian Dollar is equal to ₹2870.
How to convert Canadian dollars to rupees?The Canadian dollar is the currency of Canada. It is abbreviated with the dollar sign $, or sometimes CA$, Can$ or C$ to distinguish it from other dollar-denominated currencies. It is divided into 100 cents.
Converting the Canadian Dollar to rupees use 1 NC=0.011670 CD.
1 QR=30 NC
55/157 CD=30 NC
55/157×1/30×CD=1 NC
1 NC=0.011670CD
₹2870=0.01167×2870 CD=33.49 CD
Therefore, ₹2870 is equal to 33.49 CD.

Answer:
x=7
Step-by-step explanation:
You would set them equal to each other and solve for x.
We set them equal to each other becuase they are congruent.
Answer:
x=7
Step-by-step explanation:
we know that both degrees are equal to each
other so we set (17x-10)=(15x+4)
Let's solve your equation step-by-step.
17x−10=15x+4
Step 1: Subtract 15x from both sides.
17x−10−15x=15x+4−15x
2x−10=4
Step 2: Add 10 to both sides.
2x−10+10=4+10
2x=14
Step 3: Divide both sides by 2.

Answer:
Answer is 50 Inches or 4 feet, 2 inches
Step-by-step explanation:
First I would make everything inches so that it's easier:
2 feet is 24 inches, 1 foot is 12 inches
Then, add everything:
24+8+12+6 = 50 inches
You can leave the answer like this, or convert to feet again: (since there are 12 inches in a foot, divide 50 by 12. It's easiest to keep it as a mixed number.)
50/12 = 4 2/12
Answer is 50 Inches or 4 feet, 2 inches
