Answer:

958.990

Step-by-step explanation:

958.990 is the Round off to the nearest hundred.

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.

The solution to a system of equations is where the lines intersect, which are: A. (-2,0) C. (1, -3)

When a system of equations is represented on a graph, the solution to the system of equations is simply the coordinates of the points where the line of the equations intersect.

Thus, the lines intersect at (-2,0) and (1, -3). Therefore, the solution to the system of equations are: A. (-2,0) C. (1, -3)

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

Answer:

  A, B, C, E, D

  F, G, H, I, J

Step-by-step explanation:

You can go at this a couple of ways.

Consider the squares of number 1 through 9.

  [tex]\begin{array}{cccccccccc}n&1&2&3&4&5&6&7&8&9\\n^2&1&4&9&16&25&36&49&64&81\end{array}[/tex]

Then when the number under the radical is close to n², the root on the number line will be close to n.

The other way you can do this is to find the square root using your calculator.

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.

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

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.

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

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.

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

The insurance company can expect to make $900 on the policy

Step-by-step explanation:

The given parameters are;

The amount Ted pays per year for insurance on his home = $1,400

The value of the insurance policy = $5000

The chance that Ted will make a claim on the policy = 10%

The expected value is given as follows

Incidence    [tex]{}[/tex]                 Probability        Value                                   v × p

A claim is made  [tex]{}[/tex]          0.1                  $5,000 - $1,400 = -$3,600    -$360

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.

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.
