Round 958.989730738 to the nearest hundred
Answer:
958.990
Step-by-step explanation:
958.990 is the Round off to the nearest hundred.
What is rounding a number to some specific place?Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
The digit 5 acts as a limit.
If the digit on right is 5, and after it there is only zeros or no value, then we round up (increase by 1, as we did in 347500 -> 34800 ) (Well there are many detailed rules of rounding)
WE have to Round 958.989730738 to the nearest hundred.
Hence, 958.990 is the Round off to the nearest hundred.

Working together, Candice and Ximena painted a fence in 8 hours. Last year, Ximena painted the fence by herself. The year before, Candice painted it by herself, but took 12 hours less than Ximena took. How long did Candice and Ximena take, when each was painting alone?
Answer: Time taken by Ximena to paint the fence alone = 24 hours
Time taken by Candice to paint the fence alone = 12 hours
Step-by-step explanation:
Let x= Time taken by Ximena to paint the fence alone .
Time taken by Candice to paint the fence alone = x-12
As per given , we have
[tex]\dfrac{1}{x}+\dfrac{1}{x-12}=\dfrac{1}{8}\\\\\Rightarrow\ \dfrac{x-12+x}{x(x-12)}=\dfrac{1}{8}\\\\\Rightarrow\ 8(2x-12)=x^2-12x\\\\\Rightarrow\ 16x-96=x^2-12x\\\\\Rightarrow\ x^2-12x-16x+96=0\\\\\Rightarrow\ x^2-28x+96=0\\\\\Rightarrow\ x^2-4x-24x+96=0\\\\\Rightarrow\ x(x-4)-24(x-4)=0\\\\\Rightarrow\ (x-4)(x-24)=0\\\\\Rightarrow x=4, 24[/tex]
if x= 4
Time taken by Ximena = 4 hours
Time taken by Candice = 4-12 hours =-8 hours which is not possible. (time cannot be negative)
Therefore, x= 24
Such that
Time taken by Ximena to paint the fence alone = 24 hours
Time taken by Candice to paint the fence alone = 24-12=12 hours

I am having trouble understanding this: Sam bought 86 pounds of flour for his bakery. Every day he used the same amount of flour to make bakery items. After 10 days, Sam was left with 25.2 pounds of flour. On average, how many pounds of flour did Sam use each day?
A. 3.01 Pounds
B. 5.65 Pounds
C. 6.08 Pounds
D. 11.12 Pounds
Please also include an explanation. Thanks!
Answer:
the average amount of flour used each day=6.08 pounds
Step-by-step explanation:
Sam bought 86 pounds of flour for his bakery.
Every day he used the same amount of flour to make bakery items.
After 10 days, Sam was left with 25.2 pounds of flour.
Now we are asked to find the average pounds of flour that Sam used each day.
Total amount of flour used=86-25.2=60.8 pounds.
As he used the flour equal amount each day for 10 days.
So, the average flour used each day=
amount of flour used/ number of days=60.8/10=6.08.
the average amount of flour used each day=6.08 pounds
Answer:
C
Step-by-step explanation:
So since Sam have 25.2 leftover pounds of flour, we can subtract that from 86, knowing that will be left over in the end. Next, we divide the number left. 86 - 25.2 = 60.8
Finally, divide that by 10, since there are 10 days.
We end up with 6.08 pounds.

What is the average rate of change of the function f(x) = 2x2 + x + 5 over the interval −2 ≤ x ≤ 2?
A. −4 B. −1 C. 1 D. 4
Answer:
d
Step-by-step explanation:
The average rate of change the function f(x) = 2x² + x + 5 is 1.
So, Option C is correct.
The average rate of change
The average rate of change in a function is the rate at which one value changes with respect to another value.
Given function: [tex]f(x)=2x^2+x+5[/tex] on interval [tex][-2,2][/tex]
Therefore,
Average rate of change = [tex]\frac{f(2)-f(-2)}{2-(-2)}[/tex]
[tex]f(2)=2(2)^2+2+5\\f(2)=15\\f(-2)=2(-2)^2-2+5\\f(2)=11[/tex]
Substitute the values,
Average rate [tex]=\frac{15-11}{2+2}[/tex]
Average rate [tex]=\frac{4}{4}[/tex]
Average rate [tex]=1[/tex]
So, the average rate of change is [tex]1[/tex]
Option C is correct.

- 2x + 3y = -8
Answer:
x = 1 ,y = -2
Step-by-step explanation:
Solve the following system:
{-4 y - 3 x = 5 | (equation 1)
3 y - 2 x = -8 | (equation 2)
Subtract 2/3 × (equation 1) from equation 2:
{-(3 x) - 4 y = 5 | (equation 1)
0 x+(17 y)/3 = -34/3 | (equation 2)
Multiply equation 2 by 3/17:
{-(3 x) - 4 y = 5 | (equation 1)
0 x+y = -2 | (equation 2)
Add 4 × (equation 2) to equation 1:
{-(3 x)+0 y = -3 | (equation 1)
0 x+y = -2 | (equation 2)
Divide equation 1 by -3:
{x+0 y = 1 | (equation 1)
0 x+y = -2 | (equation 2)
Collect results:
Answer: {x = 1 ,y = -2

Decide whether the pair of lines is parallel, perpendicular, or neither.
Ly: 2x + 3y = 8
L2:3x + 2y = 7
Choose the correct answer below.
A. The lines are neither parallel nor perpendicular.
B. The lines are perpendicular.
C. The lines are parallel.
Answer:
A
Step-by-step explanation:
We can solve for y for both of the lines' equations to get the point-slope form.
L1: [tex]y=\frac{-2}{3} x+\frac{8}{3}[/tex]
L2:[tex]y=\frac{-3}{2}x+\frac{7}{2}[/tex]
So, the slopes of the two lines are [tex]\frac{-2}{3}[/tex] and [tex]\frac{-3}{2}[/tex].
Remember that parallel lines have the same slope, and perpendicular lines have opposite and reciprocal slopes. These slopes are reciprocal but not opposite.

Bob and Carl each rented the same kind of moving truck from EZ Move. There was a flat rental fee plus a charge per mile that the truck was driven. Bob's cost for his truck was $112.96 for 138 miles. Carl's cost for his truck was $142.78 for 209 miles. Which equation can be used to represent the cost of the rental truck? Round to the nearest hundredth if necessary.
Answer:
Total cost= 55 + 0.42*x
x= miles driven
Step-by-step explanation:
Giving the following information:
Bob's cost for his truck was $112.96 for 138 miles.
Carl's cost for his truck was $142.78 for 209 miles.
To calculate the fixed cost and variable cost per mile, we need to use the high-low method:
Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)
Variable cost per unit= (142.78 - 112.96) / (209 - 138)
Variable cost per unit= $0.42 per mile
Fixed costs= Highest activity cost - (Variable cost per unit * HAU)
Fixed costs= 142.78 - (0.42*209)
Fixed costs= $55
Fixed costs= LAC - (Variable cost per unit* LAU)
Fixed costs= 112.96 - (0.42*138)
Fixed costs= $55
Finally, the cost equation:
Total cost= 55 + 0.42*x
x= miles driven

A foreign country uses the stellar as its currency. Before a trip to that country, Mia wants to exchange $1700 to steller's. Which of Bank A and Bank B has the better exchange rate? How many more steller's would she get if she exchanged her $1700 at the better exchange rate instead of at the other rate?
Answer and explanation:
Stellar is a Brazilian cryptocurrency that is used to facilitate low cost and flexible payment. It was renamed lumens and is denoted XLM.
One stellar lumen is currently equal to $0.219096
For the purpose of the question and since it does not specify exchange rates for each bank, let's assume:
Bank A= 0.219097 to 1 US dollar
Bank B= 0.219099 to 1 US dollar
Using Bank A to exchange $1700 for stellars= $1700*0.219097= 372.464 stellars
Using Bank B to exchange $1700 for stellars= $1700*0.229042= 389.3714 stellars
From the above, we can see that Bank B has a better exchange rate as it is cheaper than Bank A(gives more stellar) . She should therefore use Bank B for her exchange.
In the figure below, points J, K, and L are the midpoints of the sides of AXYZ.
Suppose JK=38, X2=96, and YX=56.
Find the following lengths.
Answer:
28 ; 76 ; 38
Step-by-step explanation:
KL = [tex]\frac{XY}{2}[/tex] = [tex]\frac{56}{2}[/tex] = 28 units
YZ = 2 × JK = 38 × 2 = 76 units
LZ = 76/2 = 38 units
The lengths are: KL = 28 units, YZ = 76 units and LZ= 38 units.
What is Mid point theorem?The line segment in a triangle connecting the midpoint of two sides of the triangle is said to be parallel to its third side and is also half the length of the third side, according to the midpoint theorem.
Given:
J, K, and L are the midpoints of the sides of ΔXYZ.
JK=38, X2=96, and YX=56.
Now, using Mid point theorem
JK= 1/2 YZ
38 = 1/2 YZ
YZ= 2 x 38
YZ = 76 units.
and, KL= 1/2 YX
KL = 1/2(56)
KL= 28
LZ = 1/2 (YZ)
LZ = 1/2(76)
LZ = 38 units
