Answer: 18
Step-by-step explanation:
First we want to turn 20% into a decimal so we can multiply it by 90.
So to do that we divide 20 by 100.
20/100=0.2 so 0.2 is the decimal form of 20%.
Then we multiply 90 by 0.2 to get 18 as our answer.
Answer:
Answer: 20% of 90 is 18.
Let's find 20% of 90.
Explanation
20% of 90 can be written as 20% × 90
= 20/100 × 90
= 18
Thus, 20% of 90 is 18.

What is the POINT in this equation y+5= 9/4 (x+25) *
Answer:
The vertex (your "point") is (-25, -5).
Step-by-step explanation:
Compare the given equation to
y - k = m(x - h). We see that the slope, m, is 9/4; the x-coordinate of the vertex is h = -25, and the y-coordinate of the vertex is k = -5.
The vertex (your "point") is (-25, -5).

b. -1.3
-3
Please select the best answer from the choices provided
Ο Α
ОВ
С
D
Answer:
A
Step-by-step explanation:
We are given that:
[tex]\tan(\theta)=1.3[/tex]
And we want to find:
[tex]\cot(90^\circ -\theta)[/tex]
Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities:
[tex]\tan(\theta)=\cot(90^\circ-\theta)\text{ and } \cot(90^\circ-\theta)=\tan(\theta)[/tex]
Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3.
Our answer is A.

How are the functions of the brain and lungs different?
The brain helps break down the food into smaller pieces, while the lungs reduce the sugar level in the blood.
The brain processes information, while the lungs inflate and deflate to help us breathe.
The brain reduces the sugar level in the blood, while the lungs pass oxygen into the blood.
The brain works with the spinal cord to send and receive messages, while the lungs filter the blood.

Spends at most 30, buys boxes of crayons that cost 2 per box, also buys a poster for 5. Wants to know how many boxes of crayons she can spend.
Answer:
for 15 crayons box she can spend
Step-by-step explanation:
The computation of the number of crayons for which she can spend is shown below:
Given that
She can spend $30
And, the cost is 2 per box
So, for the number of crayons for which she can spend is
= $30 ÷ 2
= 15 crayons box
Hence, for 15 crayons box she can spend

log (5) + log (x) - log (x-6) = 1
can someone tell me how to solve this rq
Answer:
Step-by-step explanation:
log(5) + log(X) = log(5x)
log( 5x) - log(x - 6) = log (5x/(x - 6))
antilog(log(5x/(x - 6)) = antilog(1)
5x / (x - 6) = 10 multiply both sides by x - 6
5x = 10(x - 6) remove the brackets
5x = 10x - 60 Subtract 10 x from both sides
5x - 10x = - 60
-5x = - 60 Divide by 5
x = 12
HELP ASAP!!!!! SOMEONE ABLE TO HELP??!?!?
Answer:
(x+c)(x-d)
Step-by-step explanation:
if x²-ax-b=(x-c)(x+d)
from vieta theorem
c + d = -(-a)=a
cd = b
if x²+ax-b
from vieta theorem
c + d = -(a)=-a
cd = b
so the same c d but in opposite sign (x+c)(x-d)
given y²+5y-6= (y+p) (y+q), find the values of p and q.
Answer:
(y+6)(y-1)
Step-by-step explanation:
literally factorising.
y^2 x -6 = -6y^2
u need two numbers that multiply to make -6 and add them together to make +5 which is +6 and -1.
Answer:
p = 6, q = - 1 , or p = - 1, q = 6
Step-by-step explanation:
Factorise the quadratic expression on the left side
y² + 5y - 6
Consider the factors of the constant term (- 6) which sum to give the coefficient of the y- term (+ 5)
The factors are + 6 and - 1 , since
6 × - 1 = - 6 and 6 - 1 = + 5 , then
y² + 5y - 6
= (y + 6)(y - 1) = (y - 1)(y + 6)
Compare to (y + p)(y + q) , then
p = 6, q = - 1 or p = - 1, q = 6

Answer:
x = 5
Step-by-step explanation:
Since both triangles are similar hence;
m<CAB = m<CDE
Given theta
m<CAB = 50degrees
m<CDE = 10x
Substitute the given angles
50 = 10x
Swap
10x = 50
Divide both sides by 10
10x/10 = 50/10
x = 5
Hence the value of x is 5
Find the indicated limit, if it exists.
Answer:
6
Step-by-step explanation:
As x approaches -10 from the left, f(x) approaches -4 + 10 = 6
As x approaches -10 from the right, f(x) approaches -10 + 16 = 6
f(-10) = 6
Putting that all together, we have a limit of 6

A box contains 4 pair of sunglasses. How many outcomes are in the sample space for pulling out a single pair, not returning it, then drawing out a second set of glasses.
a. 8
b. 12
c. 6
d. 9
Answer:
B.12
Step-by-step explanation:
For your first draw you have 4 possible options, then on your second draw you have 3 possible options since you took out a pair. So to figure out the number of possible outcomes you simply multiply the possibilities by each other to get the number of possible outcomes.
