help me please this will help my grade !
Answer:
the answers B and D are correct
Answer:
B & D
Step-by-step explanation:
It can-t be A, because that would mean 20², which equals 400, would equal 20.
B is correct because even though it's negative, negative times negative = positive, which would mean that (-sqrt of 20)(-sqrt of 20)=20.
C is wrong because sqrt -20 is an imaginary number,which is a completely different topic.
D is correct because it's the same thing as B, but without the 2 negaties cancelling each other out.
E is the same as A, except it's '-20' x '-20', whcih is still 400, which is still wrong

A certain drug is made from only two ingredients: compound A and compound B. There are 4 milliliters of compound A used for every 7 milliliters of compound B. If a chemist wants to make 1012 milliliters of the drug, how many milliliters of compound A are needed?
These are proportions.
Answer:
368 milliliters.
Step-by-step explanation:
Compound A + Compound B = 1 drug
4 + 7 = 1 drug
11 milliliters = 1 drug, so 1012 milliliters = 92 drugs
Multiply the compounds by the amount of drugs, e.g.
4 x 92 = 368 ( Compound A )
7 x 92 = 644 ( Compound B )
368 + 644 = 1012
368 milliliters of Compound A are needed to make 1012 milliliters of the drug.
Hope this helps :)
Scarlett and Alyssa work at a dry cleaners ironing shirts. Scarlett can iron 15 shirts per hour, and Alyssa can iron 35 shirts per hour. How many total shirts would be ironed between the two workers if Scarlett worked 5 hours and Alyssa worked 10 hours on a given day? How many total shirts would be ironed between the two workers if Scarlett worked x hours and Alyssa worked y hours on a given day?
Answer:
25x + 35(2x) = 380
25x + 70x = 380
95x = 380 so
x = 4
then i think that mean it might be 8 then im not completly sure
Write an exponential decay function to model the situation in the photo.
Correct answer will get a Brainliest, a 5star rating, and a Thanks !
Step-by-step explanation:
The formula for exponetial equation decay is
[tex]y = a(b) {}^{x} [/tex]
where a is the initial value and b is the decay factor.
A will be 56 since that our initial value.
b will be 0.9 since we are constantly decaying by 0.9.
so our equation is
[tex]y = 56(0.9) {}^{x} [/tex]
What is the equation of the line that passes through the two points (2,3) and (-2,5)
Answer: -1/2
Step-by-step explanation:
You want to find the equation for a line that passes through the points.
We use formula y2-y1/x2-x1
5-3/-2-2 = 2/-4
= -1/2
Determine all the transformations that have happened to f(x) = (x + 4)2 + 2 compared to
f(x) = x2
Answer:
Folow the steps to learn what transformations were determined.
Step-by-step explanation:
First we would have to graph the parent function which is f(x) = x^2. Start by finding your x and y values. Find the y values by plugging in the x values into the parent function.
X Y
2 4
1 1
0 0
-1 1
-2 4
Once these points are plotted you can start determining what are the transformations. Find the difference between the parent function and f(x) = (x + 4)^2 + 2 by looking below.
Vertical Shifts:
f(x) + c moves up,
f(x) - c moves down.
Horizontal Shifts:
f(x + c) moves left,
f(x - c) moves right.
The parent function has to be transformed left 4 and up 2. In order to do this shift each point from earlier left 4 and then up 2. In conclusion you will have two functions graphed (parent function and the transformed function).

Plot the zeros of this function:
f(x) = (x – 1)(x – 7).
Answer:
Zeros of the given function are x = 1, 7
Step-by-step explanation:
Given function is,
f(x) = (x - 1)(x - 7)
For zeros of the function,
f(x) = 0
(x - 1)(x - 7) = 0
(x - 1) = 0
x = 1
(x - 7) = 0
x = 7
Therefore, zeros of the given function are x = 1, 7
We can find the zeros by suing a graphing tool.
Find two integers whose sum is 10 and product is 9
Answer:
let the numbers be x and y then by given conditions:
x + y = 10 ….. eq 1
and
xy = 9….. eq 2
from eq 2. y = 9/x
put this in eq. 1
x + 9/x = 10
x + 9= 10x
x = 1
now,
xy = 9put value of x
y = 9

What is the value of x? Pls help
Answer:
x=20
Step-by-step explanation:
ok so that is a pentagon and if you didnt know all of the angles in a pentagon add up to equal 540
so we setup an equation which would be
7x+4x+5+4x+10+5x-5+6x+10=540 and now we just solve for x
step 1 combine like terms
7x+4x=11x
11x+4x=15x
15x+5x=20x
20x+6x=26x
5+10=15
15-5=10
10+10=20
now we have
20+26x=540
step 2 subtract each side by 20
20-20 cancels out
540-20=520
now we have 26x=540
the final step is to divide each side by 26
26/26 cancels out
540/26=20
x=20

Find the value of x that makes m||n. (7x - 23) (11x + 23)
(7x - 23)° + (11x + 23)° = 180°
7x - 23° + 11x + 23° = 180°
18x = 180° / : 18
x = 10°
how do you know when the solution of equations is a precise answer and when it is an approximate answer?
Answer:
an answer is precise when it is an exact number like 10, 2, or 123.
An answer is approximate when the decimal numbers are so close that could round it, and the rounded number would be equivalent to the original number. ex: 10.98 = 11
Sarah is having people over for her birthday party. If she orders 4 pizzas for 15 people, how many should she order for 30 people?
Answer: 8
Step-by-step explanation:
Answer: 8 pizzas.
Step-by-step explanation:If she is ordering 4 pizzas for 15 people then that simply means that the fraction is 4/15, 15*2 is 30, so that means that our next fraction (Equivalent fraction) will be like this 4/15 = -/30. What ever. Happens to the numerator must happen to the denominator and vice versa. So 4*2 is 8. So the answer is 8.

Step-by-step explanation:
20.50×10. +165.85=
Answer:
$370.85
Step-by-step explanation:
He started off with $165.85. So all we need to do is multiply $20.50 x 10 = $205. We need to add 165.85 + 205 = $370.85
So after 10 weeks there will be $370.85.
