Step-by-step explanation:
82282922929293
Answer:
the length of its equal sides = 26 cm
Step-by-step explanation:
A = b*h/2
h = 2*A/b
h = *240/20
h = 26 cm
hypotenuse = [tex]\sqrt{10^2 + 24^2} = 26 cm[/tex]
Determining Equivalent Expressions i'm confused on everything about it so if someone could clear it up for me. I will mark Brainliest
Answer:
Equivalent expressions
Step-by-step explanation:
Example
Lets start with numbers
1 + 2 = 3
The expression 1 + 2 is equivalent to 3
They have the same value
Now with algebras
2(x + 3) is equivalent i.e also equals to 2x + 6
3(x + 1) - 23 is equivalent to the following expressions:-
3x + 3 - 23
& 3x - 20
In conclusion equivalent expressions are different expressions that have the same values.

What is the slope intercept equation?
Answer:
y=2/3x+4
Step-by-step explanation:
M is rise over run, so in this graph is 2 rise over 3 run and positive. The y intercept is 4 because x=0 there and that is the y axis.

For which pairs of function is (g*f)(a)=|a|-2
Answer:
Option 3
Step-by-step explanation:
Option 1
f(a) = a² - 4
g(a) = √a
(gof)(a) = [tex]\sqrt{a^{2}-4}[/tex]
Option 2
f(a) = [tex]\frac{1}{2}a-1[/tex]
g(a) = 2a - 2
(gof)(a) = [tex]2[\frac{1}{2}a-1]-2[/tex]
= (a - 2) - 2
= a - 4
Option 3
f(a) = 5 + a²
g(a) = [tex]\sqrt{(a-5)}-2[/tex]
(gof)(a) = [tex]\sqrt{(a^2+5-5)}-2[/tex]
= |a| -2
Option 4
f(a) = 3 - 3a
g(a) = 4a - 5
(gof)(a) = 4(3 - 3a) - 5
= 12 - 12a - 5
= 7 - 12a
Therefore, Option 3 is the answer.
The sum of three consecutive even numbers is 552. What is the 1st number?
Answer:
Let 2n = the first of three consecutive even numbers, where n is an integer.
Let 2n + 2 = the second of three consecutive even numbers, and
Let 2n + 4 = the third of three consecutive even numbers.
We're given that "sum of three consecutive even numbers is 552." We can translate this English sentence mathematically into the following equation to be solved for n:
2n + (2n + 2) + (2n + 4) = 552
Removing the parentheses, we have:
2n + 2n + 2 + 2n + 4 = 552
Now, by the Commutative Law of Addition, i.e., a + b = b + a, we have on the left side of the equation:
2n + 2n + 2n + 2 + 4 = 552
Now, collecting like-terms on the left, we get:
6n + 6 = 552
To solve for the variable n, We now begin isolating n on the left side by subtracting 6 from both sides as follows:
6n + 6 - 6 = 552 - 6
6n + 0 = 546
6n = 546
Now, divide both sides by 6 to finally solve for n:
(6n)/6 = 546/6
(6/6)n = 546/6
(1)n = 91
n = 91
Therefore, the first of three consecutive even numbers, 2n, is:
2n = 2(91)
= 182
The second of three consecutive even numbers is:
2n + 2 = 2(91) + 2
= 182 + 2
= 184
The third of three consecutive even numbers is:
2n + 4 = 2(91) + 4
= 182 + 4
= 186
CHECK:
2n + (2n + 2) + (2n + 4) = 552
182 + 184 + 186 = 552
552 = 552
Therefore, the desired and first of three consecutive even numbers is indeed 2n = 182.

32.55 rounds to 32
Answer:
False. 32.55 rounds to 33
Step-by-step explanation:
If the number after the decimal is larger than 4, then you round up.
Answer:
This isn't true.
Step-by-step explanation:
This isn't true because the fives (5) in 32.55 causes the number to be rounded up to 32. If this doesn't make sense, please message me and I can help you further!

Mr. Fredrick burns about 2100 calories per day without exercising. For each mile that he walks, he burns an additional 150 calories. Write a linear function modeling the number of calories Mr. Fredrick burns in a given day. How many miles should Mr. Fredrick walk each day to maintain his current weight if he eats 2700 calories per day?
Answer:
4 miles
Step-by-step explanation:
2100+150x=2700
2100-2100+150x=2700-2100
150x=600
Divide by 10.
15x=60
x=4

Pablo folds a straw into a triangle with side lengths of 4x2−3 inches, 4x2−2 inches, and 4x2−1 inches. Which expression can be used to find the perimeter of the triangle, and what is the perimeter when x = 1.5?
12x2 −6; 21 inches
12x2; 27 inches
12x2 −6; 30 inches
12x2; 36 inches
Answer:
12x² - 6; 21 inches ⇒ A
Step-by-step explanation:
Let us solve the question
∵ The side lengths of a triangle are 4x² - 3 in., 4x² - 2 in., 4x² - 1 in.
∴ S1 = 4x² - 3 inches
∴ S2 = 4x² - 2 inches
∴ S3 = 4x² - 1 inches
→ The perimeter of the triangle is the sum of the lengths of its 3 sides
∵ P = S1 + S2 + S3
∴ P = 4x² - 3 + 4x² - 2 + 4x² - 1
→ Add the like terms
∵ P = (4x² + 4x² + 4x²) + (-3 + -2 + -1)
∴ P = 12x² + -6
→ Remember (+)(-) = (-)
∴ P = 12x² - 6
∴ The expression of the perimeter of the Δ is 12x² - 6
∵ x = 1.5
→ Substitute x in the perimeter expression by 1.5
∵ P = 12(1.5)² - 6
∴ P = 12(2.25) - 6
∴ P = 27 - 6
∴ P = 21 inches
∴ The perimeter of the triangle is 21 inches
The expression can be used to find the perimeter of the triangle is 12x² - 6 and its perimeter is 21 inches when x = 1.5
Answer:
its A. 12x2 −6; 21 inches

The local community center has an indoor basketball gym with two different payment options.
Option A is to buy a $21 membership card and pay $1 each time you go. Option B is to pay $4
each time you go without a membership.
When will the cost of Option A be equal to the cost of Option B?
Answer:
Step-by-step explanation: 6 visits
Answer:
Answer:
option a will be the same cost as b when its at 24 because you have to pay 21 then 1 dollar each time you go so you go 3 times and you can go 6 times till 24 on the other plan so 6 time for b and 3 for a and that's when they will be the same

Answer:
(-5, -1)
Step-by-step explanation:
Note that a parallelogram is a quadrilateral formed by two pairs of parallel lines.
Notice that to get to (0,1) from (2,7), we must move 2 to the left and 6 down. We can use this to get from (-3, 5) to the missing point.
2 to the left of (-3, 5) is (-5, 5)
6 down from (-5, 5) is (-5, -1)
Therefore, (-5, -1) is our answer.
I hope this helps!
