Answer:
774 dollars
Step-by-step explanation:
Given the amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation
y = -8x^2 + 242x – 1056
The company made her maximum profit when dy/dx = 0
dy/dx = -16x + 242
0 = -16x + 242
16x = 242
x = 242/16
x = 15.125
Get the maximum amount of the profit
Substituting x = 15.125 into the function we have:
y = -8(15.125)^2 + 242(15.125) – 1056
y = -8(228.77)+3,660.25-1056
y = -1,830.09+3,660.25-1056
y = 773.91
Hence the maximum amount of profit the company can make, to the nearest dollar is 774 dollars

if a ladder is to reach a height of 5.6m, the base must be at least 1.4m from the wall. How long should the ladder be in order to meet this safety regulations?
Answer:
≈ 5.72 mStep-by-step explanation:
Use Pythagorean as the ladder is going to be a hypotenuse of a formed right triangle with legs of 5.6 m and 1.4 m
Ladder length:
√5.6² + 1.4² = √32.76 ≈ 5.72 m roundedI WILL GIVE THE REST OF MY POINTS (100 SOMETHING) TO THE PERSON WHO ANSWERS THIS RIGHT BY CREATING A NEW QUESTION AND ALSO WILL GIVE BRANLIEST
Mr. Townsend needs to make 13 pairs of butterfly wings for costumes for a play.
Each pair of wings is made with yard of fabric. The fabric costs $8 per yard.
You'll apply properties of multiplication in the following steps to find the total cost of the fabric.
1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings.
2. Multiply the amount of fabric by the price per yard to find an expression for the total cost.
3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with.
4. Simplify your expression to find the total cost. Show your work
Step-by-step explanation to answer:
So, the unit rate is $8 per yard of fabric now we need a expression which will be 13 times 8. 8 times 10 is 80 and 8 times 3 is 24. 80+24 is 104. We did associative, now we need communative. We will still get the answer to the question as we did with associative which will be 8 times 3 is 24 and 8 times 10 is 80. add that and we will get 104.
19 dozen cookies to individual cookies
Answer:
228 individual cookies.
Step-by-step explanation:
To convert 19 dozen cookies to individual cookies, we first have to identify that:
[tex]dozen=12[/tex]
If a dozen is equal to 12, to solve, we simply must multiply the amount of dozens, which is 19, by a dozen, which is 12:
[tex]19*12=[/tex]
[tex]228[/tex]
Therefore, there are 228 individual cookies.
-
We can check our work by dividing the individual number of cookies, 228, by dividing buy the amount of dozens, 19, and a dozen, 12:
[tex]228[/tex] ÷ [tex]19=12[/tex]
[tex]228[/tex] ÷ [tex]12=19[/tex]
As you can see, our quotients are the two figures we started with, and when multiplied together, give us 228 individual cookies; therefore, our solution is correct!
51. (08.02 MC) Box A has a volume of 48 cubic meters. Box B is similar to box A. To create Box B, Box A's dimensions were doubled. What is the volume of Box B? (1 point)
Answer:
384 m³
Step-by-step explanation:
Let the dimension of box a be l,b, and h.
ATQ,
lbh = 48 .....(1)
If we double the dimension of box A, we get box B whose new dimensions will be 2l,2b and 2h.
Let V be the volume of box B.
V = (2l)(2b)(2h)
V = 8(lbh)
= 8(48) [from equation (1)]
= 384 m³
Hence, the volume of the box B is 384 m³.
find tan a in a triangle
a 20/21
b 21/29
c 21/20
d 20/29
Answer:
Option C
Step-by-step explanation:
By applying tan rule in the given triangle ABC,
tan(a) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{BC}{AC}[/tex]
= [tex]\frac{21}{20}[/tex]
Therefore, Option C is the correct option.

A tree is 6 feet high. Each year, x, it grows 2 feet. Write an equation to model the height, y, of the tree after x years. What is the height of the tree after 7 years?
Answer:
1) y=2x+6
Step-by-step explanation:
2) y=2×7+6=20ft
Answer:
y = 2x + 6 and the height is 20 feet after seven years.
Step-by-step explanation:
Hello we meet again.
You substitute the x with 7 and then it will be 2(7)+6. 2 times 7 is 14 plus 6 equals 20 so good luck.

Lana has 6 bags with 3 candy bars in each bag. Markus has 3 bags with 4 candy bars in each bag. How many more candy bars does Lana have?
Answer:
Lana has 6 more candy bars than Markus.
Step-by-step explanation:
Lana has 6 bags, each with 3 candy bars. To find the total amount you multiply 6 by 3 which is 18. Markus has 3 bags, each with 4 candy bars, to find the total amount you also multiply 3 by 4 which is 12. Now you subtract: 18-12=6. So Lana has 6 more candy bars than Markus.
Answer:
Lana has 6 candy bars more than Markus
Step-by-step explanation:
6 x 3 = 18
3 x 4 = 12
18 - 12 = 6

Anna drives 45 km to work each day.
One day she drives the first 25 km at an average speed of 82 km/h. She takes 36 minutes to drive the remaining distance.
Calculate her average speed, in km/h, for the whole journey.
Answer:
Anna drove at an average speed of 49.73 km/h
Step-by-step explanation:
Average Speed
If an object moves at different speeds to cover a certain total distance dt in a total time tt, the average speed is:
[tex]\displaystyle \bar v=\frac{d_t}{t_t}[/tex]
Anna drives a total distance of dt=45 km each day. One day she drives a distance of d1=25 km at v1=82 Km/h. The time taken for that distance is:
[tex]\displaystyle t_1=\frac{d_1}{v_1}=\frac{25}{82}=0.3049\ h[/tex]
She takes t2=36 minutes to drive the remaining distance. 36 minutes is 36/60=0.6 h, thus the total time is:
[tex]t_t=0.3049\ h+0.6\ h=0.9049\ h[/tex]
The average speed is:
[tex]\displaystyle \bar v=\frac{45}{0.9049}=49.73\ km/h[/tex]
Anna drove at an average speed of 49.73 km/h
A cuboid with a volume of 924cm^3 has dimensions 4cm, (x+1)cm and (x+11)cm.
Show clearly that x^2+12x-220=0
Solve by factorisation, making sure you show the factorisation. Find the dimensions of the cuboid.
Answer:
Dimensions = 4cm, 11cm and 21cm
OR
Dimensions = 4cm, -21cm and -11cm
Step-by-step explanation:
Solving the quadratic equation by using the factorization method;
x² + 12x - 220 = 0
Factors = 22 and -10
x² + 22x - 10x - 220 = 0
x(x + 22) - 10(x + 220) = 0
(x - 10)(x + 22) = 0
Therefore, x = 10 or x = -22
Given the following data;
Length of one side = (x + 1)cm
When x = 10
Length of one side = (10 + 1)cm
Length of one side = 11cm.
When x = -22
Length of one side = (-22 + 1)cm
Length of one side = -21cm
Length of the other side = (x + 11)cm
When x = 10
Length of the other side = (10 + 11)cm
Length of the other side = 21cm
When x = -22
Length of the other side = (-22 + 11)cm
Length of the other side = -11cm
Check;
Volume of a cuboid = L*L*L
Volume of a cuboid = 4 * 11 * 21
Volume of a cuboid = 924cm³

We know that 2 socks are in a pair. Hence, the rate would be like this: 2 socks/pair. We could also represent it as a ratio and fraction. I will choose the fraction form.

2 socks = 34 socks
1 pair x 17 17 pairs
Therefore, if Vera owns 17 pairs of socks, she will have 34 socks in total.
