Answer:
= a⁸/b⁻¹⁰
Step-by-step explanation:
Simplify the expression
(a^2b^-3/a^-2b^2)^2
= a⁴b⁻⁶/a⁻⁴b⁴
Using the law of indices
= a⁴⁻⁽⁻⁴⁾/b⁻⁶⁻⁴
= a⁴⁺⁴/b⁻¹⁰
= a⁸/b⁻¹⁰

In parallelogram QRST, diagonals QS and RT intersect at point E. Which statement must be true? QS ⊥ RT ΔRES ≅ ΔTEQ ∠RQS ≅ ∠SQT ΔTQE ≅ ΔRQE
Answers
Answer:
ΔRES ≅ ΔTEQ
Step-by-step explanation:
A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel to each other.
Opposite angles of a parallelogram are equal and the diagonals bisect each other. Each diagonal of a parallelogram separates it into two congruent triangles.
Given parallelogram QRST with diagonals QS and RT intersecting at point E
Therefore, the diagonals divide parallelogram QRST into congruent triangles, hence:
ΔRES ≅ ΔTEQ

Solve this linear system:
3x + 4y − z = −6
5x + 8y + 2z = 2
−x + y + z = 0
Answers
Answer:
Part 1
|A| = -23
|Ax| = -46
|Ay| = 46
|Az| = -92
Part 2
X = 2
Y = -2
Z = 4
Step-by-step explanation:
The values of x, y and z from the given system of equations are 2, -2 and 4 respectively.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
The given system of equations are
3x+4y-z =-6 ---------------(i)
5x+8y+2z=2 ----------(ii)
-x+y+z=0 ---------------(iii)
From equation (iii), z=x-y
Substitute z=x-y in equation (i), we get
3x+4y-(x-y)=-6
3x+4y-x+y=-6
2x+5y=-6 -----------(iv)
Substitute z=x-y in equation (ii), we get
5x+8y+2(x-y)=2
5x+8y+2x-2y=2
7x+6y=2 -----------(v)
From equation (iv) and (v), we have
7(2x+5y=-6)
-2(7x+6y=2)
14x+35y=-42
-14x-12y=-4
__________
23y=-46
y=-2
Substitute y=-2 in equation (v), we get
7x+6(-2)=2
7x=14
x=2
Substitute x=2 and y=-2 in equation (iii), we get
-2-2+z=0
z=4
Hence, the values of x, y and z are 2, -2 and 4 respectively.

The range of the project will be equal to 0.82.
What is the range in statistics?When the sample maximum and minimum are subtracted, the range of a set of data is the difference between the largest and smallest values. It uses the same units as the data to express itself.
The given data of the project is,
u 0.87
v 0.31
w 0.08
x 0.05
y 0.19
z 0.5
The range will be calculated as the difference between the maximum value to the minimum value.
Range = 0.84 - 0.05
Range = 0.82
Therefore, the range of the project will be equal to 0.82.

Beth and Bryce sign on a $205,000 mortgage at a 5% annual interest rate for 30 years. This results in a monthly payment of $1100.48. If only the minimum payment is made in month one, how much of the first payment goes toward reducing her balance?
Answers
Answer: $246.31
Step-by-step explanation:
The monthly payment of $1,100.48 is going to be divided into interest and principal repayment which is the one that reduces her balance.
The interest payment is based on the interest rate which is 5%.
Monthly interest is:
= 205,000 * 5% * 1/12 months because it is monthly
= $854.17
The amount that goes towards reducing her balance is:
= Monthly payment - Interest payment
= 1,100.48 - 854.17
= $246.31

how can you tell just by looking at the numerator and denominator of a fraction if it is closer to 0 or 1? Give some examples in your explanation.
Help
Answers
if you look at the numerator, and it is greater than the denominator, this means that it is closer to 1 than it is to 0. an example is 8/5. since the numerator is greater than the denomator, we know that the fraction is closer to 1.
If denominator of the fraction is greater than numerator then it is closer to 0 or 1.
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
Given that;
The fraction is closer to 0 or 1.
Now,
Let a fraction as;
⇒ 4 / 7
Then, It is equivalent to,
⇒ 4 / 7 = 0.57
Which is closer to 0 or 1.
So, We can conclude that;
⇒ If denominator of the fraction is greater than numerator then it is closer to 0 or 1.

Lina is packing to move to a new house. She has 561 items to transfer to the new house. 36 of the items are large items that will be carried alone.
Answers
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let me give different scenarios to help you solve.
Firstly, assuming we want to calculate the amount of items left after the large items are carried alone, this will be:
= 561 - 36
= 525
Secondly, if we want to know the percentage of the large items that will be carried alone. This will be:
= 36/561 × 100.
= 6.42%
Thirdly, if you want to know the percentage of the items that will be left after the large ones have been carried alone. This will be:
= 100% - 6.42%
= 93.58%

A farmer plans crops on 48 acres of land. The circle graph shows the percentages of land used for some of the different types of crops.
Based on the circle graph, how many acres of land are used for corn?
Answers
Answer:
14.4 acres for corn (if you need to round, it's 14 acres.)
Step-by-step explanation:
40% = 19.2 acres
20% = 9.6 acres
10% = 4.8 acres
40 + 20 + 10 = 70
100-70 = 30
30% = 14.4 acres
Answer:
14.4acres
Step-by-step explanation:
The total acres is 48 acres, which is 100%
when you add percentage of others, wheat and cotton you get 70%.
which leaves you with 30%
therefore, 30% of the land is for corn..
which is 14.4 acres.
0.30 x 48acres= 14.4 acres
