Answer:
product of powerspower of a powernegative exponentStep-by-step explanation:
The value in square brackets is evaluated using the product of powers rule:
(7^5)(7^3) = 7^(5+3) = 7^8
Then the overall value is found using the power of a power rule:
[7^8]^-4 = 7^(8(-4)) = 7^-32
Finally, the expression value is found using the negative exponent rule:
7^(-32) = 1/7^32 = 1/1104427674243920646305299201
In the 1800s, wagon trains traveled west along the oregon trail. A wagon train traveled from missouri to wyoming in 1 2/3 months and from wyoming to utah in 3/5 month. About how many months did it take the wagon train to travel from missouri to utah?
Answer: 2 4/15 months
Step-by-step explanation:
From the question, we are informed that a wagon train traveled from Missouri to Wyoming in 1 2/3 months and from Wyoming to Utah in 3/5 month.
The number of months that it will take the wagon train to travel from Missouri to Utah will be:
= 1 2/3 + 3/5
The common lowest multiple is 15
= 1 10/15 + 9/15
= 1 19/15
= 1 + 1 4/15
= 2 4/15 months
It will take they train 2 4/15 months to travel from Missouri to Utah.

What values of x and y simultaneously satisfy the two equations given?
y = 2x – 3
y =[tex]\frac{1}{3}[tex] x + 2
9514 1404 393
Answer:
(x, y) = (3, 3)
Step-by-step explanation:
The two expressions for y can be set equal:
2x -3 = 1/3x +2
5/3x = 5 . . . . . . add 5 -1/3x
x = 3 . . . . . . . . . multiply by 3/5
y = 2(3) -3 = 3 . . . find y using the first equation
The solution to the system of equations is (x, y) = (3, 3).
For a craft project, Jackie cuts the two triangles described below out of fabric. Find the length of CE¯¯¯¯¯¯¯¯.
In triangle CDE, CD¯¯¯¯¯¯¯¯=7 cm, CE¯¯¯¯¯¯¯¯=(4z+7) cm, ∡C=48°, and ∡E=82°. In triangle TUV, UV¯¯¯¯¯¯¯¯=(13z−20) cm, UT¯¯¯¯¯¯¯=7 cm, ∡U=48°, and ∡V=82°.
Answer: ???
Answer:
19
Step-by-step explanation:
took the test
Given:
In triangle CDE, CD=7 cm, CE=(4z+7) cm, ∡C=48°, and ∡E=82°.
In triangle TUV, UV=(13z−20) cm, UT=7 cm, ∡U=48°, and ∡V=82°.
To find:
The length of CE.
Solution:
In triangle CDE and triangle UTV,
[tex]m\angle C=m\angle U[/tex] (Given)
[tex]m\angle E=m\angle V[/tex] (Given)
[tex]CD=UT[/tex] (Given)
Two angles and a non -included side are equal in both triangle. So, both triangles are congruent by AAS postulate.
[tex]\Delta CDE\cong \Delta UTV[/tex]
[tex]CE=UV[/tex] (CPCTC)
[tex]4z+7=13z-20[/tex]
[tex]4z-13z=-7-20[/tex]
[tex]-9z=-27[/tex]
Divide both sides by -9.
[tex]z=3[/tex]
Now,
[tex]CE=4(3)+7[/tex]
[tex]CE=12+7[/tex]
[tex]CE=19[/tex]
Therefore, the length of CE is 19 cm.

$1500 at 9% for 2 years
Answer:
Step-by-step explanation:
You basicly want to use A=pe^rt to find the amount of money you now have. A is the total amount of money you have after a certian period of time (T) while your money grows at a steady rate (R). (E) is an irrational number 2.71828. (P) is the amount of money you started with. Your precentage is your rate and this means you earn 9% of what you have per year. The way the problem would be set up A=1500(2.71828)^(.09)(2). This problem allows for exponential growth to occur because your two variables are time and the amount you have in that time.

One rectangle is devided into four parts. How much is one part?
Answer:
[tex]P = \¼R[/tex]
Step-by-step explanation:
Given
Shape: Rectangle
Division = 4 parts
Required
How much is one part of the division
Represent the rectangle with R and the parts with P
When a rectangle (R) is divided into 4 parts (P); the relationship between R and P is:
[tex]P = \frac{R}{4}[/tex]
[tex]P = \¼R[/tex]
This implies that the one part of the division is ¼ of the divided rectangle

Answer:
4
Step-by-step explanation:
Since the coefficients must be real and one of the roots is 1-i, then there has to be another root which is 1+i so that the coefficients can be real. Summing up all of the roots, we see there are 4 roots that just be part of the equation: 3, 4, 1-i, and 1+i. Since it is asking for the least, it has to be 4. Since the number of roots is the degree, the least it can be is 4.

Sasha works as a babysitter. She charges $20 for the job plus an additional $5 per hour. Sasha and her family will soon be leaving for vacation, and Sasha would like to have at least $70 for spending money. How many hours does Sasha need to work to earn her goal?
Answer:
She would have to work 10 hours.
Step-by-step explanation:
She charges 20 to do the job but 5 for every hour well she already has 20 cause thats what she charges to do the job and sine 5x10=50
50+20=$70 so she will need to work 10 hours to be able to spend $70 on trip
A map has a 1 inch to 200 miles scale. If Atlanta is 15 inches away from Los Angeles on the map, how far apart are they in real life?
A: 3000 miles
B: 300 inches
C: 300 miles
D: 30 miles
Answer: A) 3000 miles
Step-by-step explanation:
B, C, and D couldn't possibly be correct.
Answer:
A: 3,000
Step-by-step explanation:
If one inch on the map is equivalent to 200 miles in real life the equation would look like 200i=m, i representing inches and m representing miles. To solve this certain equation you would mulitiply 200 by 15 which is 3,000

3. To combine the equations and solve for one of the variables, you need to eliminate the other
variable. How can you change one equation so that one variable is eliminated when the two
equations are added? Explain and write the new equation. (3 points: 2 for your explanation and
1 for the equation)
Answer:
If we multiply equation 2 with -6 and add both equations, we can eliminate variable y. The equation is given and solved below.
Step-by-step explanation:
The equations given are:
12x+6y=120
4x+y=30
We need to find How can you change one equation so that one variable is eliminated when the two equations are added?
Let:
[tex]12x+6y=120--eq(1)\\4x+y=30--eq(2)[/tex]
If we multiply equation 2 with -6 and add both equations, we can eliminate variable y.
Solving
[tex]12x+6y=120\\-24x-6y=-180\\---------\\-12x+0y=-60\\-12x=-60\\x=\frac{-60}{-12}\\x=5[/tex]
So, we eliminated the variable y and found the value of x.
Now Putting value of x in any of above equations we can find value of y.
[tex]4x+y=30\\4(5)+y=30\\y=30-20\\y=10[/tex]
So, we get value of y=10
