Answer:
13,280 cm²
Step-by-step explanation:
The formula for the area of a cuboid can be written as ...
A = 2(LW +H(L +W))
When the area of the missing top is subtracted, this becomes ...
A = LW +2H(L +W)
Then the area of 10 boxes will be ...
A = 10×(20×16 +2×14(20+16)) = 10(320 +28(36)) = 13,280 cm²

Shane is a salesperson. He earns an hourly wage of $8.00 per hour, plus he receives a commission of 7% on sales he makes. Write an equation which would be used to determine his weekly salary, W, where, X, is the number of hours worked, and Y, is the amount of sales for the week.
Answer:
8X+.07Y=W
Step-by-step explanation:
x is your hours and y is your sales
he makes 8 an hour, hence 8X or 8 x X
7 percent written as a decimal is .07 and his commission for sales, so .07Y
add them together and you get your equation:
8X+.07Y=W

help please ill mark brainlyist 25 pts. A rabbit is 4m away from its burrow. Each hop takes it 0.4 farther from the burrow. The following diagram shows that there is a tasty plant that is 6m text from the burrow.
Which equation can we use to determine h, the number of hops it takes the rabbit to reach the plant?
Choose 1 answer:
Answer:
C
Step-by-step explanation:
He is already 4 m away from the burrow and the plant is 6 meters away the plant is the goal and each hop brings him 0.4 closer so you would multiply 0.4 by the amount of hops and add 4 and it should equal 6 ex: 4+0.4h=6
if you where to solve for h you would get the amount of hops you need. hope this was helpful :D

Answer: The y-intercept is 3. The slope is 1.
Step-by-step explanation: Since the y coordinate is intercepting the y axis, the y-intercept is 3. To find the slope, the formula is change of y over change of x. The coordinates on this plane is (0,3) and (-3,0). That means the equation is (3-0) divided by (0-(-3)). That equals 3 divided by 3 which is obviously 1. Mark Brainliest plz!

(3x + 1) (x - 2)

Please help me, I can’t figure this one out.
Answer:
A. This scatter plot has no association, no form, weak strength, and no apparent outliers.
Step-by-step explanation:
The scatter shows several data points plotted on the graph, of which show no particular trend.
Every data point on the plot are far apart from each other and do not follow any trend or have any shape, and as such show very weak strength.
We can hardly pick out which data point is an outlier.
There's also no form of association or whatsoever since no trend can be observed.
Therefore, we can conclude that:
"This scatter plot has no association, no form, weak strength, and no apparent outliers."

Can someone not tell me the answer but walk me through this because I don't get what this question is asking.
Which unit rate is equivalent to 15 miles per gallon?
thirty miles over three gallons
three gallons over thirty miles
four gallons over sixty miles
sixty miles over four gallons
Answer:
sixty miles over four gallons
Step-by-step explanation:
The “over” word means divide, so let’s change all of these choices into expressions and evaluate them:
thirty miles over three gallons -> 30 mi/3 gal = 10 mi/gal
three gallons over thirty miles -> 3 gal/30mi = 1 gal/10 mi = 0.1 gal/mi (because it is asking for unit rate)
four gallons over sixty miles -> 4 gal/60 mi = 15 gal/mi
sixty miles over four gallons -> 60 mi/4 gal = 15 mi/gal
The problem is asking for which unit rate is equivalent to 15 mi/gal. We see that this fits the last choice (the value and the units). Therefore, the last choice is our answer.
I hope this helps! :)
Answer:
Step-by-step explanation:
It is asking you what is equal if 1g= 15miles.
If 1g=15 miles,
then 2g=30 miles,
3g=45miles,
and etc.
Each gallon can drive for 15 miles, so multiplying the number of gallons by 15 will tell you how many miles that person can drive.
Ex. 1x15=15 miles,
2x15=30 miles
3x15= 45 miles
Hope this helps!

There are c amount in a box . 11 of the counters are green. Benedict take 20 counters at random from the box. 4 of these counters are green. Work out the estimate for the value of c.
Answer:
There are total 55 counters out of which 11 are green and 44 are other color.
Step-by-step explanation:
This is a ratio and proportion question. There are c amount of counters in the box .
The chosen have the same ratio as in the box
Green : total
4: 20
11: x
Using cross product rule
x * 4= 20 *11
x= 20*11/4
x= 55
So there are total 55 counters out of which 11 are green and 44 are other color.
Benedict take 20 counters out of which 4 are green.
Total number of counters are 55 in which 11 counters are green and 44 counters are other color.
Ratio and proportion:There are c amount in a box.
11 of the counters are green.
We have to find number of counters.
[tex]\frac{c}{11}=\frac{20}{4}\\ \\ 4*c=20*11\\\\c=\frac{20*11}{4}\\ \\c=55[/tex]
Hence, total number of counters are 55 in which 11 counters are green and 44 counters are other color.

The sum of the numbers X, Y, and Z is 40. The ratio of X to Y is 1:2 and the ratio of Y to X is 2:5. What is the value of Y?
Step-by-step explanation:
Since X : Y = 1 : 2, X = 0.5Y.
Since Y : Z = 2 : 5, Z = 2.5Y.
We have X + Y + Z = 4Y = 40. Hence Y = 10.

Ratio:A ratio in mathematics shows how many times one number is contained in another. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio of 4:3). The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8 (or 3:4) (or 4:7).A ratio can have any number of quantities, such as counts of people or things or measurements of length, weight, time, etc. Both numbers must be positive in most situations.Solution -
Given -
[tex]x+y+z=40\\x:y=1:2\\y:x=2:5[/tex]
To find - [tex]y[/tex]
Since,
[tex]x:y=1:2,x=0.5y\\y:x=2:5,z=2.5y\\x+y+z=4y+40\\y=10[/tex]

equal to (-28)(-1). Who is correct? *
O Josh

O Both
O No one
Answer:
Evangelina and Josh can be considered correct but this can be simplified to just 28. so if you want the simplification of this problem it would be no one but both are correct if you just want to see if they equal the same answer
Step-by-step explanation:
they are correct because they could simplify it
Evangelina and Josh can be considered correct but this can be simplified to 28.
What is simplification of an expression?Usually, simplification involves proceeding with the pending operations in the expression. Like, 5 + 2 is an expression whose simplified form can be obtained by doing the pending addition, which results in 7 as its simplified form. Simplification usually involves making the expression simple and easy to use later.
Given that Josh says that (4)(-7)(-1) is equal to (4)(7).
Evangelina says (4)(-7)(-1) is equal to (-28)(-1).
(4)(-7)(-1) = (4)(7) =28
Similalray;
(-28)(-1) = 28
We can see that the answer of the both the simplification are correct.
