Answer:
21.87
Step-by-step explanation:
Christina estimated 188% of 91 by performing these steps. What did she do wrong?
(90) (190 percent) = (90) (100 percent + 90 percent) = (90) (100 percent) + (90) (90 percent) = (90) (1.0) + (90) (0.9) = 90 + 18 = 108.
She rounded 188% up to 190%.
She rounded 91 down to 90.
She incorrectly broke 190% into 100 percent + 90 percent.
She incorrectly multiplied 90 and 0.9.
Answer:
D) she incorrectly multiplyed 90 and 0.9.

Step-by-step explanation:
Anna and Jason have summer jobs stuffing envelopes for two different companies. Anna earns $14 for every 400 envelopes she finishes. Jason earns $9 for every 300 envelopes he finishes. I need someone to solve this but represent it on a table instead of a graph.
Answer:
Q1: 20,000 envelopes
Q2: Savings = $700
Step-by-step explanation:
Let the number of envelopes stuffed by each be "x"
We can create 2 equations, each for Anna and Jason, equate them and find our answer.
For Anna:
$14 for 400, so
14/400 = $0.035 PER ENVELOPE
Savings for Anna is 0.035x
For Jason:
Already has 100 (fixed)
Gets $9 for 300 envelopes, so
9/300 = $0.03 PER ENVELOPE
Savings for Jason is 100 + 0.03x
We equate and solve for x:
So, For both their savings to be equal, they need to stuff 20,000 envelopes
Their savings would be:
0.035x
or 100 + 0.03x
We can plug in x = 20,000 in any one equation, the answer would be same.
So,
0.035(20,000) = $700
savings = $700

please help meeee
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]14x - 76 + 8x + 2 = 180[/tex]
[tex]14x + 8x + 2 - 76 = 180[/tex]
[tex]22x - 74 = 180[/tex]
Add sides 74
[tex]22x - 74 + 74 = 180 + 74[/tex]
[tex]22x = 254[/tex]
Divide sides by 22
[tex] \frac{22}{22} x = \frac{254}{22} \\ [/tex]
[tex]x = \frac{127}{11} \\ [/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Answer:
x = [tex]\frac{127}{11}[/tex]
Step-by-step explanation:
14x - 76 + 8x + 2 = 180
Collect like terms;
22x - 74 = 180
Add 74 to both sides;
22x = 254
Divide both sides by 22;
x = [tex]\frac{254}{22}=\frac{127}{11}[/tex]

Apples: $(2x) per pound
Grapes: $(6x - 5) per pound
Oranges: $(x + 2) per pound
A shopper purchases one pound each of
apples, grapes, and oranges and spends
$10.50. How much is spent on each type
of fruit?
Answer:
x= 1.5 $
Step-by-step explanation:
Hi there,
This is a tough question. Let us find out how to tackle it.
From the problem, we see that we 'll have to find x to figure out how much each type is. The only real number of money we get is 10.50$ - the amount the shopper spent. Let's divide this money into respective parts:
He bought 1 pound of apple => the cost of all the apple he bought is 1 ( pound) × (2x) ($ per pound) = 2x $
Do the same with Grapes and Oranges, we can easily see that he spent 6x-5 $ on grapes, x+2 $ on oranges.
The total amount he spent 10.50$ is now equal to (2x) + (6x-5) + (x+2).
Next we can change this equation, just so we find x easier:
10.50$ = (2x) + (6x-5) + (x+2)
10.50$ = 2x + 6x + x + 2 - 5
10.50$= 9x - 3
13.50$= 9x
x= 1.50 $
Thus, we can now calculate the price of each type. Apples are 3$ per pound, grapes are 4$ per pound, oranges are 3.50$ per pound.
HOPE YOU'LL LEARM WITH JOY AND GOOD GRADE
Answer:
Shopper spend on Apples $3 , on Grapes $4 and on Oranges $3.5
Step-by-step explanation:
We are given:
Apples: $(2x) per pound
Grapes: $(6x - 5) per pound
Oranges: $(x + 2) per pound
A shopper purchases one pound each of apples, grapes, and oranges and spends $10.50.
It can be written as: [tex]2x+6x-5+x+2=10.50[/tex]
We need to find how much the shopper spend on each fruit.
Solution:
Now, we need to find value of x by solving equation
[tex]2x+6x-5+x+2=10.50[/tex]
Solving:
[tex]2x+6x+x+2-5=10.50\\9x-3=10.50\\9x=10.50+3\\9x=13.5\\x=\frac{13.5}{9}\\x=1.5[/tex]
The value of x is: x=1.5
Now finding cost of one pound each fruit by putting x=1.5
Apples: $(2x) per pound
$2x= 2(1.5) = $3
Grapes: $(6x - 5) per pound
$(6x-5) = (6(1.5)-5)= $4
Oranges: $(x + 2) per pound
$(x+2)=(1.5+2)=$3.5
So, shopper spend on apples $3, on Grapes $4 and on Oranges $3.5.

if you shift the reciprocal parent function, f(x)=1/x, right 4 units, what is the equation of the new function
Answer: I think it is f(x)=1/(x-4)
Step-by-step explanation:
By taking f(x), and applying a left or right and/or up or down transformations to it, the function could be written using the equation f(x-h)+k.
Doing so will make the graph of the function move h units to the left or right. (Positive or negative) (make sure the operation before the h is subtraction when determining the sign of h)
Also, when finding k (up and down) (positive or negative) apply this function.
f(x)=(x-h)+k
As a result, plug in your right 4 units as h, and since you are not needing to move up or down k would be 0. So, f(x)=1/(x-(4))+0 or simplified, f(x)=1/(x-4)
Answer:
F(x)=1/x-4

4
inches of chain to make one bracelet. How many bracelets can she make from a chain that is
49
1
2
inches long?
9514 1404 393
Answer:
6
Step-by-step explanation:
We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:
6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2
Sue can make 6 bracelets.
_____
You can also divide the total length of chain by the amount per bracelet:
(49 1/2)/(8 1/4) = (99/2)/(33/4)
= (99/2)(4/33) = (99/33)(4/2)
= (3)(2) = 6
Answer:
6
Step-by-step explanation:
We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:
6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2
Sue can make 6 bracelets.
_____
You can also divide the total length of chain by the amount per bracelet:
(49 1/2)/(8 1/4) = (99/2)/(33/4)
= (99/2)(4/33) = (99/33)(4/2)
= (3)(2) = 6

Answer my math question I asked so many times I lost most of points by
Answer:
i think ur in a higher grade then me but im good w/ equations so OoOO0p
Step-by-step explanation:
equation: y = x - 6 + x^2
(6,0) (7,1) (8,4) (9,9)
I figured this out by looking at the point (6,0). To get 0 (y), you have to subtract 6. Knowing this, I subtracted 6 from the rest of the coordinates, leaving me with numbers that are able to be squared to get y. This led me to the equation x - 6 + x^2.

Wilmer went up a hill for x minutes at a speed of y kilometers per minutes. Then he went down the same path at a speed of z kilometers per minute, and it took him w minutes to do it. Write an equation that relates x, y, z, and w. (The wording for this question really confuses me. And I do not understand which variable to put on it's own.) PLEASE ANSWER
Answer:
[tex]xy=wz[/tex]
Step-by-step explanation:
Given that:
Speed of Wilmer up the hill = [tex]y[/tex] km/min
Time taken up the hill = [tex]x[/tex] minutes
Speed of Wilmer down the hill = [tex]z[/tex] km/min
Time taken up the hill = [tex]w[/tex] minutes
Distance can be calculated by multiplying the Speed with Time i.e.
The formula for distance is given as:
[tex]Distance = Speed \times Time[/tex]
Distance up the hill = [tex]y\times x =xy\ kilometers[/tex]
Distance down the hill = [tex]z\times w =wz\ kilometers[/tex]
It is well known that, the distance up the hill and down the hill will be same.
Putting both the values equal, we get:
[tex]xy=wz[/tex]

xy=wz

Answer choices:
A. 4.0 kg
B. 3.0 kg
C. 14.52 kg
D. .33 kg
E. 8.6 kg
Answer:
B
Step-by-step explanation:
2.2lb = 1 kg
6.6/2.2=3.0kg
The correct weight of the baby is given by option B) 3.0 kg
What is the unitary method?The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
Given here, the baby's weight as 6.6 lbs and 1 lb=0.45 kg
Thus 6.6 lbs=6.6×0.45
= 3.0 ( approx)
Hence, The correct weight of the baby is given by option B) 3.0 kg
