THEN Using your answer, find the perimeter of the triangle.
Answer:
Perimeter of the triangle is 58
Step-by-step explanation:
create an equation
(x+3)2+(2x-1)2=(x-7)+(4x-8)+(3x+1)
2x+6+4x-2=x-7+4x-8+3x+1
combine like terms
6x+4=8x-14
18=2x
x=9
now we substitute in the expression to find the perimeter
9-7=2
36-8=28
27+1=28
2+28+28=30+28=58

How many times greater than 6 x 10^6 is 2.4 x 10^8 ? Show ur work
Answer:
40 times greater
Step-by-step explanation:
6 x 10^6 = 2.4 x 10^8
6 x 1000000 = 2.4 x 100000000
6000000 = 240000000

hi can you help me with this problem ? 15 points
Answer:
30 cakes
Step-by-step explanation:
For one cake alone, find a common denominator (which is 6). So [tex]2\frac{2}{3}[/tex] ([tex]\frac{8}{3}[/tex]) is equal to [tex]\frac{16}{6}[/tex] cups. [tex]\frac{1}{2}[/tex] is [tex]\frac{3}{6}[/tex] cups.
So for one cake, it takes [tex]\frac{19}{6}[/tex] cups of flour. Henry has [tex]\frac{570}{6} = 95[/tex] cups of flour.
If you divide the 570 by 19, Henry can make 30 cakes.

During the year 2013 approximately 7.07 x10 to the power of 9 pennies were minted (made by the U.S. Mint). In the year
2000 approximately 1.43x 10 to the power of 10 were minted. Estimate how many times more pennies were minted in the
year 2000 compared to the year 2013. Give a possible explanation for the decline.
Using proportions, it is found that 2.04 times more pennies were minted in the year 2000 compared to the year 2013.
What is a proportion?A proportion is a fraction of a total amount. From it, the amount of times a measure a is greater than a measure b is given by a divided by b.
In this problem:
In 2013, the quantity was of [tex]7.07 \times 10^9[/tex].In 2000, the quantity was of [tex]1.43 \times 10^{10}[/tex]Hence, 2.04 times more pennies were minted in the year 2000 compared to the year 2013.
Hence, applying the proportion:
[tex]\frac{1.43 \times 10^{10}}{7.07 \times 10^9} = \frac{14.3 \times 10^9}{7.07 \times 10^9} = 2.04[/tex]

Write the equation of the line that
passes through the point (4, 3) and is
PERPENDICULAR to the line y = 2x - 4
Answer:
y=-1/2x+2
Step-by-step explanation:
First, the slope of perpendicular line have negative reciprocal coefficients. In this case the coefficient is 2, The reciprocal of 2 is 1/2 and the negative of 1/2 is -1/2. So x will have a coefficient of -1/2.
Second, find the equation with a slope of -1/2 that passes through (-2,3). There are a few ways to do this. I like to plug the given x value into the expression -1/2x, so -1/2(-2) which equals positive 1 and for the line to pass through the point (-2,3) you need to add 2. So: y=-1/2x+2

James's bag has 15 red marbles, 10 blue marbles and 5 green marbles.
They each take a marble out of their bag without looking.
Select the statements that are correct:
-
A - They both have the same probability of picking a blue marble.
B - The probability of Alex picking a red marble is 50%.
C - They both have the same probability of picking a red marble.
D - The probability of James picking a green marble is 5%.
E - James has a higher chance of picking a red marble than Alex.
Answer:
[B] The probability of Alex picking a red marble is 50%.
[C] They both have the same probability of picking a red marble.
Step-by-step explanation:
Given;
Alex and James both have a bag of marbles.
Alex's bag has 10 red marbles and 10 blue marbles.
James's bag has 15 red marbles, 10 blue marbles and 5 green marbles.
They each take a marble out of their bag without looking.
Solve;
Alex have 10 Blue marbles so 10 out of 20 are Blue.
James has 10 Blue Marbles so 10 out of 30 are Blue.
Hence, [A] They both have the same probability of picking a blue marble.
is False.
Alex have 10 red and 10 blue which 10 = 10
thus, [B] The probability of Alex picking a red marble is 50%.
Alex's have 10 red marbles and James's have 15 red marbles.
10 out of 20 of them are red. Thus, that 50%
15 out of 30 of them are red. Thus, that 50%
50% = 50%
Hence, [C] They both have the same probability of picking a red marble.
is true.
James have 15 red, 10 Blue, 5 Green marbles.
15 + 10 + 5 =30 [ Total ]
5 out of 30 is Green
5/30 = 0.16666666666
Round = 16.67%
Hence, [D] The probability of James picking a green marble is 5%.
is False.
15 out of 30 and 10 out of 20
15/30 = 50% and 10/20 = 50%
Thus, [E] James has a higher chance of picking a red marble than Alex.
is False.

Find the hypotenuse round to the nearest hundredth
Answer:
7.62
Use the Pythagorean theorem. (a^2)+(b^2)=(c^2)
(3^2)+(7^2)=58
Then the square root of 58 is 7.61577 rounding that to the hundredths gives you 7.62
7.62
To round find the hypotenuse, use the Pythagorean theorem which states that A squared plus B squared = C squared which is the answer to our problem. Then find the square root of the solution and voila.

Rahul was given a large box of 60 chocolates for his birthday. If he eats exactly 4
chocolates each day, how many chocolates would Rahul have remaining 9 days after
his birthday?
Answer:
He'll have 24 chocolates remaining.
Step-by-step explanation:
Lets make an equation to represent the problem where x = the number of days and c = chocolates remaining.
60 - 4x = c
Since he ate four chocolates everyday for 9 days, the x in this equation would be 9.
Multiply 9 by 4 to get 36, Then subtract that from 60 to get 24.

Step-by-step explanation:
Solving for the equations,
x² + 4y² = 361
4x² + y² = 324
Add both equations
5x² + 5y² = 685
Divide both sides by 5
x² + y² = 137
Multiply both sides by 4
4x² + 4y² = 548
Now take the square of both sides.

What is the solution to the equation?
x^2=40
Will give brainliest if correct and explained!!
Answer: 2√10
Step-by-step explanation:
A way we can find what x equals, is to find the opposite of what ever sign is on a side, in the equation x^2=40, the opposite of squaring is to find the square root of it.
It is important that what you do to one side, you do to the other.
So we have to square root both sides so we can get rid of the ^2 on x to get x =. This would look like √x^2 = √40
The square root of x^2 would revert back to just x
To find the square root of 40, its important to first see if its a perfect square. In this scenario, it isnt. Because it isnt, we have to find the closest perfect square that we can multiply to get 40, in this equation, the closest would be 4 so we do 4*10.
Then we reduce the 4 by square root and we get 2
Then we cant do anything else with the 10, so we would right the answer as a radical, with the square root you got from the perfect square on the outside and the remainder on the inside of the square root, like x√r where x is the number obtained from square root and r is the remainder that we cant do anything else with.
After doing this, we get the answer 2√10, which can be said "two radical ten"
