The two leg lengths of a triangle are 21 and 28 ft. What is the length of the hypotenuse?
Answer:
588
Step-by-step explanation:
Answer
The length of the hypotenuse is 35 feet.
Explanation
This is the formula to find the hypotenuse.
[tex]l^{2} + l^{2} = h^{2}[/tex]
One leg is 21 feet. The other is 28 feet. Now insert those into the formula.
[tex]21^{2} + 28^{2} = h^{2}[/tex]
[tex]h^{2}=1225[/tex]
Now to find what h is you should find the square root of 1225.
[tex]\sqrt{1225} =35[/tex]
So the length of the hypotenuse is 35 feet.
Can you help me solve this problem please?

Answer:
A) 55 + x ≤ 100
B) 55 + x ≤ 70
Step-by-step explanation:
A Explanation - Inequalities use signs < , > , ≤ , and ≥. We also know you have 100 seconds to beat the level, so you have to solve it in 100 or less, which tells us the 55 + the time left (x) must be less than or equal to 100. Solved will be attached.
B Explaination -
Like A, you can use the same setup, but switching a value. You already have the 55, you need 70. Or less points to ≤, same as before, so you can keep it the same, except with the 70 instead of the 100. Solved attached.
Solve the equation using the zero-product property 4X(X + 4) = 0
Answer:
X = 0 or X = -4
Step-by-step explanation:
4X(X + 4) = 0
4 = 0 or X = 0 or X + 4 = 0
Since 4 = 0 is false, we eliminate that equation.
X = 0 or X + 4 = 0
X = 0 or X = -4

Amare runs 1/10 mile in 2/3 minutes. What is his speed in miles per minute
Answer:
6 2/3 minutes
Step-by-step explanation:
Amare runs 1/10 mile in 2/3 minutes
Therefore his speed in miles per minutes clean be calculated as follows
= 1/10, the denominator here is 10
= 10 × 2/3
= 20/3
= 6 2/3 minutes

Beth wants to paint her rectangular night stand that is 42 inches long and 28 inches wide. A quart of paint covers about 350 square inches. How many quarts of paint will Beth need to cover the entire night stand?
Answer:
3.36 quarts of paint
Step-by-step explanation:
In this question, we're trying to find how much paint she will need to cover the night stand.
First, we need to find the area.
Solve for the area (rectangle = l * w):
42 · 28 = 1176
Now, we know that 1 quart of paint covers 350 square inches.
To find how much paint she needs, divide 1176 by 350:
1176/350 = 3.36
This means that she needs 3.36 quarts of paint to cover her whole nightstand.

Answer: 2(3 x + 5)
Explination: 2(3x) = 6x which is also 3 + 3
2(5) = 10 which is also 5+5

a number is chosen at random from 1 to 25. find the probability of selecting a number less than 3?
Answer: Because we are finding the probability of selecting a number less than three, you are left with two options. The answer would be either one, or two.
If you were to also use three it wouldn´t be correct because three is equivalent to three.

Identify the solution to the system of equations graphed below.
Given f(x) = 2x2 – 3x + 7, find f(2.5)
Answer:
f(2.5)=3.5
Step-by-step explanation:
f(x)=2×2-3x+7
So,
f(2.5)=2×2-3×2.5+7
=4-7.5+7
=11-7.5
=3.5

Alejandro made an error in the steps below when determining the equation of the line that is perpendicular to the line 4x – 3y = –8 and passes through the point (3, –2).
Answer:
y=-3/4x+1/4
Step-by-step explanation:
This is the concept of equations of graphs; We are required to calculate for the equation if the line that is perpendicular to the line 4x-3y=-8 and passes through point (3,-2).
Here we proceed as follows;
4x-3y=-8 can be written in he form y=mx+c as follows;
-3y=-4x-8
thus;
y=4/3x+8/3
The slope of the line perpendicular to this is -3/4. Thus using point (3,-2) the equation will be as follows;
-3/4=(y--2)/(x-3)
-3/4(x-3)=y+2
y+2=-3/4(x-3)
y+2=-3/4x+9/4
thus;
y=-3/4x+1/4
the answer is:
y=-3/4x+1/4

For what value of k is the expression

A.
B.
C.
D.
E.
64
32
16
8
4.
Answer:
[tex]k = 4[/tex]
Step-by-step explanation:
Given
[tex]4x^2 - 8x + k[/tex]
Required
Determine k if the expression is a perfect square
A quadratic is of the form;
[tex]ax^2 + bx + c[/tex]
Where (by comparison):
[tex]a = 4[/tex] [tex]b = 8[/tex] [tex]c = k[/tex]
If the above is a perfect square, then
[tex]k = \frac{b^2}{4a}[/tex]
Substitute values for a, b and c
[tex]k = \frac{8^2}{4*4}[/tex]
[tex]k = \frac{64}{16}[/tex]
[tex]k = 4[/tex]
Hence, k = 4
