Answer: 4.00, 9.00, 11.00, 4.00
Step-by-step explanation:
When we round, we round from the digit one smaller than the one we're rounding to. In this case, since we're rounding to the dollar, we round from the 10th place. To round, we need to know whether the number we're rounding from is smaller than, equal to, or larger than 5. If the number is smaller than 5, we round down. Larger, and we round up. If the number is equal to 5, we also round up.

What is the gradient of the graph shown?Give your answer in its simplest form.
Answer:
gradient = 1
Step-by-step explanation:
calculate the gradient using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (2, 0) ← 2 points on the line
m = [tex]\frac{0-(-2)}{2-0}[/tex] = [tex]\frac{0+2}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1
[tex]\underline{\underline{\large\bf{Solution:-}}}\\[/tex]
[tex]\longrightarrow[/tex]By observing the graph of the line , we can observes that it intersects x- axis at 2 and y -axis at -2 i.e., it passes through (2,0) and (0,-2) respectively.

A vanilla thickshake is $2 more than a fruit juice. If 3 vanilla thinkshakes and 5 fruit juices cost $30, determine their individual price.
Answer:
vanilla=$5 and fruit juice=$3
Step-by-step explanation:
let $x and $y denote the cost of vanilla thickshake and fruit juice respectively.
Now,
$x=$y+2$ (Given)-----(i)
3×$x + 5×$y =30
3×($y+$2)+5×$y=30 (From equation i )
3×$y +$6 + 5×$y = 30
8×$y + $6 = $30
8×$y= $24
.: $y =$3
Then,
From i
$x =$y+$2
=$3+$2

The Panthers baseball team needs new equipment. They plan to purchase bats that cost $60 each and gloves that cost $25 each. The number of bats they will purchase is half the number of gloves they will purchase. If they have $700, how many of each can they buy?
Answer:
Therefore, they can buy
6.36 bats and 12.72gloves
Step-by-step explanation:
Let us represent:
The number of bats purchased = b
The number of gloves purchased = g
We are told in the question that:
The number of bats they will purchase is half the number of gloves
b = 1/2g
b = g/2
g = 2b
The teams plan to purchase bats that cost $60 each and gloves that cost $25 each. they will purchase. If they have $700, how many of each can they buy?
Hence:
$60 × b + $25 × g = $700
= 60b + 25g = 700
We substitute 2b for g
60b + 25(2b) = 700
60b + 50b = 700
110b = 700
b = 700/110
b = 6.3636363636
b = 6.36 bats
Therefore, the number of bats they can buy = 6.36 bats
Remember:
g = 2b
b = 6.36
Hence,
g = 2 × 6.36
g =12.72
Therefore, the number of gloves = 12.72 gloves
Ex.) y varies inversely with x. If x = -2 when y = -8, find y when x = -4.
Answer:
y = -4
Step-by-step explanation:
Since x and y vary inversely, we have:
xy=k
For x= -2 and y = -8, we have:
⇒ -2×-8=k
⇒ k= 16
For x= -4, we have :
⇒ -4y=16
⇒ y= 16/-4
⇒ y= -4
[RevyBreeze]
Answer:
y = -4
Step-by-step explanation:
The equation for inverse variation is
xy = k where k is a constant
x=-2 and y = -8 so we can find k
-2 * -8 = k
16 = k
The equation is xy = 16
Know we want to find y when x = -4
-4 *y =16
Divide each side by -4
-4y /-4 = 16/-4
y = -4
Wanda rides her bike 5 hours a week. How many hours does she ride in 4 weeks?
Answer:
20
Step-by-step explanation:
We can put the rate of hours a week as 5. Since in this case hours will substitute for distance, and distance=speed*time, then the amount of hours will be 5*4=20.
edit: mistyped
Answer:
20 hours
Step-by-step explanation:
Given the following question:
5 hours per week
How many hours does she ride in 4 weeks?
We know the amount of hours Wanda rides per week, so this is a simple multiplication problem.
[tex]5h\times4w[/tex]
[tex]5\times4=20[/tex]
[tex]=20[/tex]
Wanda rides her bike for "20 hours" in 4 weeks.

Find the total amount given the original price, tax rate and tip rate. Round to the nearest hundredth if necessary.
Original price: $90.34
Tax rate: 3.5%
Tip: 20%
Enter the correct answer in the box.
Answer:
$111.5699. Round to hundredths $111.57
Step-by-step explanation:
First identify the %
20% =.20 20/100= .20
3.5% = .035 3.5/100= .035
Then Find the tax rate and tip
Tax Rate .035 × 90.34
= $3.1619 (tax rate)
Tip. is .20× 90.34
= $18.068 (tip)
Final Add all it up tax rate+ tip + original price
$90.34. Don't forget to line up your demicals
$3.1619. or use a calculator
+ $18.068
Total = $111.5699
round to the nearest hundredth
$111.57 is your total
Owen measured a line to be 17.9 inches long. If the actual length of the line is 17.8 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
Answer:
0.6%
Step-by-step explanation:
Percent Error = the absolute value of (actual value observed-expected value)/(expected value) x100%
(17.8-17.9)/(17.9) = -0.006
Absolute value is 0.006
0.006 times 100% equals 0.6%
The percent error of the measurement in the length is 10%.
What is percent error in measurement?Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage.Given is that Owen measured a line to be 17.9 inches long. The actual length of the line is 17.8 inches.
We can calculate the percentage error as -
%e = {(A.V. - E.V.)/(A.V.)} x 100
%e = (17.9 - 17.8) x 100
%e = 0.1 x 100
%e = 10%
Therefore, the percent error of the measurement in the length is 10%.

35n/35 = 700/35
Answer:
20
Step-by-step explanation:
[tex]\frac{35n}{35} =\frac{700}{35} \\[/tex]
multiply both sides by 35
[tex]35*\frac{35n}{35} = 700 * 35\\35n = 700[/tex]
divide both sides by 35
[tex]n = 20[/tex]
Answer:
N = 20
Step-by-step explanation:
Move all terms to the left
35n/35-(700/35)=0
Add all of the numbers together, and all of the variables
35n/35-20=0
Multiply all of the terms by the denominator
35n-20*35=0
Add all of the numbers together, and all of the variables
35n-700=0
Move all of the terms containing N to the left, all other terms to the right
35n=700
n=700/35
n=20

If the length of a rectangle is g inches and the width is h inches:
Write two equivalent expressions to represent the perimeter of the rectangle.
If the width is 4. 7 in, and the perimeter is 68. 4in, calculate the length of the rectangle.
Perimeter: h + h + g +g = P or 2h + 2g = P
P = 2h + 2g
68.4 = 2(4.7) + 2g
68.4 = 9.4 + 2g
59 = 2g
g = 29.5
Length: 29.5 inches
Consider the expression (1.0045)^4t that represents the interest earned on a money
market account, where t is the time In years. What is the approximate yearly interest rate? Round your percent to the nearest tenth. INCLUDE THE % SYMBOL IN YOUR ANSWER
The approximate yearly interest rate is 1.02%
Exponential equationsGiven the expression that represents the interest earned on a money given as (1.0045)^4t
In order to calculate the approximate yearly percent, we will substitute t = 1 into the expression as shown:
f(t) = (1.0045)^4t
f(1) = (1.0045)^4(1)
f(1) = (1.0045)^4
f(1) = 1.018

You have the right idea for the slope, but I would use a slash as shown above to indicate a fraction. It looks like you're subtracting 3 and 4 based on what you typed in. Though that might be the division symbol (it's a bit blurry so I can't see it fully/clearly)

The ages of two groups of karate students are shown in the following dot plots:
(Imported image)
The mean absolute deviation (MAD) for group A is 2.07 and the MAD for group B is 5.51. Which of the following observations can be made using these data?
1. Group A has greater variability in the data.
2. Group A has less variability in the data.
3. Group B has a lower range.
4. Group B has a lower mean.
Thank you so much for your help! Xx
Answer:
From the graph and data points, you can observe that Group B has a HIGHER range and has a greater variability. so it's NOT 1. 4. or 3. THEREFORE it's 2.
Explanation:
You start out by finding the mean (finding the sum of the data values and then dividing the sum by the number of data values)
and subtracting the first plot by the last in each graph.
