The value of the expression is -53.
What is an expression?An expression or algebraic expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them.
Given expression
m2 - 71 +22..................(1)
m = -2 and n = 5
Substitute m = -2 and n = 5 in equation(1)
⇒ m2 - 71 +22
⇒ (-2) × 2 - 71 + 22
⇒ -4 -71 +22
⇒ -75 + 22
⇒ -53
Hence, the value of the expression is -53.

Jessica's friend Tyshaun found an account that earns 2.5 percent interest compounded annually. Tyshaun made an initial deposit of $100 into this account at the same time Jessica made a deposit of $100 into her account. After 10 years, how much more money will Tyshaun's initial deposit have earned than Jessica's initial deposit?
Answer:
Tyshaun's initial deposit have earned $28.01 more money than Jessica's initial deposit
Step-by-step explanation:
As given, Jessica's initial deposit = $100
Tyshaun initial deposit = $ 100
As given, Tyshaun account earns 2.5 percent interest compounded annually.
rate = 2.5% = 0.025
so, after t= 10 years
Payment = P[tex](1+r)^{t}[/tex] = 100[tex](1+0.025)^{10}[/tex] = 100[tex](1.025)^{10}[/tex] = 128.01
So ,
Interest = Money earned by Tayshaun - Jessica's initial deposit
= 128.01 - 100
= 28.01
∴ we get
Tyshaun's initial deposit have earned $28.01 more money than Jessica's initial deposit

In the diagram below AB is parallel to CD what is the value of x
The value of x is 150°. The correct option is D. 150°
Calculating anglesFrom the question, we are to determine the measure of angle x
In the given diagram, we can observe that
The angle supplementary with x is 30° (Alternate angles theorem)
Thus,
x + 30° = 180° (Supplementary angles)
x = 180° - 30°
x = 150°
Hence, the value of x is 150°. The correct option is D. 150°

After running for 5/6 of an hour, Konnor is 1/3 of the way through his run. How long will it take Konnor to finish his run if he continues at the same pace?
Answer:
2.5 hours
Step-by-step explanation:
We need to find the rate at which Konnor runs. So his speed = distance/time.
Let x be his total distance. The distance covered in 5/6 of an hour is x/3. So, his speed is x/3 ÷ 5/6 = x/3 × 6/5 = 2x/5
Now, the rest of the distance left to cover is 1 - 1/3 = 2/3. So, the remaining distance is 2x/3.
The time required to cover this distance is t = 2x/3 ÷ speed = 2x/3 ÷ 2x/5 = 2x/3 × 5/2x = 5/3 of an hour.
So, the total time required for Konnor to complete his run is 5/6 + 5/3 of an hour = 5/6 + 5/3
= (5 + 10)/6
= 15/6
= 5/2 of an hour
= 2.5 hours

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityAlgebra I
Terms/CoefficientsStep-by-step explanation:
Step 1: Define
3.6y = 1.6y + 24
Step 2: Solve for y
[Subtraction Property of Equality] Subtract 1.6y on both sides: 2y = 24[Division Property of Equality] Divide 2 on both sides: y = 12Step 3: Check
Plug in y into the original equation to verify it's a solution.
Substitute in y: 3.6(12) = 1.6(12) + 24Multiply: 43.2 = 19.2 + 24Add: 43.2 = 43.2Here we have 43.2 does indeed equal 43.2.
∴ y = 12 is the solution to the equation.

The number of birds in a forest is decreasing by 3% every
year. If in one year it has 5400 birds, how many birds will be
there in 7 years? Round to the nearest whole number.
birds
Answer:
4266
Step-by-step explanation:
Okay! let's start with finding what 3% of 5400 birds is
3% is .03 as a decimal. We can find 3% of 5400 by multiplying 5400 by .03
5400×.03= 162
If our rainforest is losing 3% a year, that means we are losing 162 birds a year.
Let's turn it into an equation! x will be the number of years
5400-162x= number of birds left after x years
Now put 7 in for x
5400-(162×7)= 4266 birds

f = {(x, y): y = 2x + 3} and D= {2, 4, 6} then, find Range of f
Answer:
R= {7, 11, 15}
Step-by-step explanation:
Since we already know what the Domain is for f (2, 4, 6) we can use that to get the range
Since the domain is also x let's replace x for 2
y=2(2)+3= 4+3=7
One of the range is 7
Replace x for 4
y=2(4)+3= 8+3= 11
One of the other range is 11
Replace x for 6
y= 2(6)+3= 12+3= 15
The last range is 15
So the range is R= {7, 11, 15}
