LeAnn is purchasing.giftwrap for a box that measures 10 inches long, 6 inches wide, and 6 inches tall. Calculate the total area of the box that will be covered in.giftwrap. Show all of your work for full credit.
Answer:
[tex]\boxed{312~in^2}[/tex]
Step-by-step explanation:
(P) Long = 10 in
(L) Wide = 6 in
(T) Tall = 6 in
.
So, Total area is
[tex]= 2(P\times L + P \times T + L\times T)[/tex]
[tex]= 2(10\times 6 + 10 \times 6 + 6\times 6)[/tex]
[tex]= 2(60 + 60 + 36)[/tex]
[tex]= 2(156)[/tex]
[tex]= 312~in^2[/tex]
.

Step-by-step explanation:
The sum of two numbers is 26. Their dif.
ference is 4. Find the smaller number
Answer:
The smaller number is 11
Step-by-step explanation:
Let x represent one number and y represent the other.
Since the sum of 2 number is 26, x + y = 26.
The difference of the 2 numbers is 4, so x - y = 4.
x + y = 26
x - y = 4
Solve by combing the two equations:
x + x + y - y = 26 + 4
2x = 30
x = 15
x - y = 4
15 - y = 4
y = 15 - 4 = 11
Since 11 < 15, the smaller number, y , is 11.

s Yesterday, two friends went bank to open savings accounts. Reid started by putting $100 in his account, and
he will deposit an additional $40 each week. Akira made no initial deposit, but she will add $50 more each week. In
a few weeks, the friends will have the same account balance. How many weeks will that take?
runt Balance
Answer:
The two friends will have same account balance in 10 weeks.
Step-by-step explanation:
Given that:
Amount deposited by Reid = $100
Amount deposited each week = $40
Let,
x be the number of weeks.
R(x) = 40x + 100
Amount deposited by Akira each week = $50
A(x) = 50x
For the two friends to have same account balance,
A(x) = R(x)
50x=40x+100
50x-40x=100
10x=100
Dividing both sides by 10
[tex]\frac{10x}{10}=\frac{100}{10}\\x=10[/tex]
Hence,
The two friends will have same account balance in 10 weeks.

Answer:
It would be 4:6
Step-by-step explanation:
2*2=4
3*2=6
they both multiply by 2
hopefully that makes sense.
Answer:
C
Step-by-step explanation:
Because to get 4:6 you have to multiply 2:3 by 2 on each side
2 times 2 equals 4, and 3 times 2 equals 6

9 is subtracted by the sqaure of a number
Answer:
I believe it is x^2-9
Step-by-step explanation:
Since we don't have a specific "number" you use x. It says it's squared to put an exponent of 2. It also says that 9 is subtracted by it so put -9.

Estimate the solution of the system of equations. Write the answer as an ordered pair.
Answer:
(-3, 1)
The solution is the point at which both lines intersect.
This is the solution since both lines would have that point and only that ppoint in this type of problem. IN a graph where 2 lines are parralel, there is no solution as they never intersect . on a graph where the 2 lines overlap there is infinite solutions. FInally in a graph like this there is exactly one solution and it is the intersection of both lines

Cindy has test scores of 72,80,85,82,77. What does Cindy need to score on her last test for her average grade to be between a 80 and 82?
Answer:
70 ≥ (73 + 83 + 85 + 90 + 2x) / 6 ≥ 79
70 ≥ (331 + 2x) / 6 ≥ 79
____
72,80,85,82,77.=396(5 tests)82*6 = 492 (6 tests)492-396=96.If I am supposed to use 82 as the mean or main mark then I'll get 96 for her average grade to be between 80 and 82.Use this same procedure if you have any mean score in mind ✍️✍️✍️✍️Can you work out the question in the picture please

Remark
The gradient is the same thing as m in y = mx + b. The point is used to find b.
Step One
Find the gradient and put it in the right place for y = mx + b
m = 2
y = mx + b
y = 2x + b So far this is the answer. Now we go on
Step Two
Use the point to find b
y = 4
x = 1
y = 2x + b
4 = 2*1 + b
b = 4-2
b = 2
Answer
y = 2x + 2

how do i do this? (solve for x) 3(2x + 4) =2x - 8
Answer:
x = -5
Step-by-step explanation:
3 (2x + 4) = 2x - 8
6x + 12 = 2x - 8
- 2x - 2x

8xy -- 3y + 2 ( 9x - 5y + 4 ) if x = 3, y = - 4
Answer:
8xy-3y + 2(9x-5y+4) = 18
Step-by-step explanation:
We need to find the value of the given expression:
8xy-3y + 2(9x-5y+4) ....(1)
when x = 3 and y = -4
Put the values of a and y in equation (1)
8×3×(-4)-3(-4)+ 2(9×3-5(-4)+4)
= -96 +12 + 2(27 + 20 +4)
= -84 + 2(51)
= -84 + 102
= 18
Hence, the value of the given expression is 18.

Answer:30
Step-by-step explanation:
used a smart caculator
According to wildlife experts, the rate at which crickets chirp per minute is a function of the temperature in degrees Fahrenheit. James observed that when the temp was 60 degrees, there were 84 chirps and when the temp was 85 degrees, there were 184 chirps. Write a linear function to model the relationship between the number of chirps and the temperature.
Answer:
Step-by-step explanation:
We will let the x coordinates be the temp and the y coordinates by the number of chirps. Our coordinates then will look like this:
(60, 84) and (85, 184). If this is linear, then first we will find the slope of the line which will tell us, in the context of this problem, how many chirps a cricket gives per 1 degree of temp increase.
The slope formula is:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] and filling in our numbers:
[tex]m=\frac{184-84}{85-60}=\frac{100}{25}= 4[/tex]
This means that for every 1 degree temp increase, a cricket will give 4 chirps. That's the m value in y = mx + b. Now we will pick one of the coordinates, doesn't matter which one, and use those x and y values in the point-slope form of a line to get the equation. I will choose (60, 85), just because. Using the other point will give you the exact same line equation, I PROMISE!
Using 85 as y1 and 60 as x1 in
y - y1 = m(x - x1) gives us
y - 85 = 4(x - 60) and
y - 85 = 4x - 240 and
y = 4x - 240 + 85 and
y = 4x - 155
