Answer:
1 carton
Step-by-step explanation:
The volume of the carton: ~11404 cm^3
The volume of 1 scoop: ~113.1 cm^3
100 scoops --> 113.1 x 100 = ~11310 cm^3
11310<11404 --> ester will need 1 carton because 100 scoops won't fill more than one.

When the points below are connected, they will form triangle ABC. Show and state whether this triangle has a right angle or not. (Hint: Use slope to prove that there is a 90 degree angle) Drawing a graph will not award you any marks. *
A(-6,3) B(0,5) C(2,-1)
PLS HURRY I NEED ALL THE STEPS TOO THANK YOU!!!!!
Answer:
See explanartions below
Step-by-step explanation:
Given the coordinates A(-6,3) B(0,5) C(2,-1)
We first need to get the slope of AB, BC and AC
For AB;
A(-6,3) B(0,5)
Mab = 5-3/0-(-6)
Mab = 2/6
Mab = 1/3
For BC;
B(0,5) C(2,-1)
Mbc = -1-5/2-0
Mbc = -6/2
Mc = -3
For AC:
A(-6,3) C(2,-1)
Mac = -1-3/2-(-6)
MAc = -4/8
Mac = -1/2
Taking the product of Mab and Mbc
Mab * Mbc = 1/3 + -3
Mab * Mbc = -1
Since the product of Mab and Mbc is -1, hence AB abd BC are perpendicular showing that one of the angle of triangle ABC is 90 degrees

For two independent events A and B, Pr(A or B) = 0.8 and Pr(B) = 0.3. From this, find Pr(A).
Answer:
please give me brainlist and follow
Step-by-step explanation:
Correct option is
A
5/7
As A and B are independent
0.8=P(A∪B)=P(A)+P(B)−P(A)P(B)
=0.3+P(B)−(0.3)P(B)
⇒0.5=(0.7)P(B)⇒7P(B)=5
Sam is making wheels for tricycle. He can make 400 wheels in 2 hours. how many hours will it take him to make 1,000 wheels.
Answer:
5 hours.
Step-by-step explanation:
800 wheels in 4 hours.
Half of 400 is 200.
Half one 2 is 1
So 1000 wheels. 5 hours.

Answer: A). V = 1/3(3)(3)(5)
Step-by-step explanation:
• Use the volume of a pyramid formula: V = 1/3Bh, where h is height, V is volume, and B is the base area.
• The base area is length (l) • width (w), so use that to substitute B.
• Substitute the values to get the answer: A). V = 1/3(3)(3)(5)

If a rectangle is 19.6 m on one side and 24 m on the other side what would be the perimeter and area
Answer:
Perimeter = 87.2 m
Area = 470.4 square meters
Step-by-step explanation:
Formula to get the perimeter of a rectangle = 2(length + width)
= 2(19.6 + 24)
= 2(43.6)
= 87.2 m
Similarly by using formula to get the area of the rectangle,
Area = Length × Width
= 19.6 × 24
= 470.4 m²
Using Cramer’s rule, what is the value of x in the solution to the system of linear equations below?

9514 1404 393
Answer:
d 2
Step-by-step explanation:
The system of equations can be written in augmented matrix form as ...
[tex]\displaystyle\left[\begin{array}{cc|c}-\frac{1}{2}&3&-4\\-1&-1&-1\end{array}\right][/tex]
The value of x found by Cramer's rule is the ratio of two determinants. The numerator is the coefficient matrix with the x-column replaced by the constant column. The denominator is the coefficient matrix.
[tex]\displaystyle x=\frac{\left|\begin{array}{cc}-4&3\\-1&-1\end{array}\right| }{\left|\begin{array}{cc}-\frac{1}{2}&3\\-1&-1\end{array}\right|}=\frac{(-4)(-1)-(-1)(3)}{(-\frac{1}{2})(-1)-(-1)(3)}=\frac{4+3}{\frac{1}{2}+3}\\\\\boxed{x=2}[/tex]
Using the Cramer's rule, the value of x in the system of equation is 2
How to solve for x?The system of equation is given as:
-1/2x + 3y = -4
-x - y = -1
Represent the above equation as a matrix
[tex]\left[\begin{array}{cc}-1/2&3\\-1&-1\end{array}\right] \left[\begin{array}{c}-4&-1\end{array}\right][/tex]
Start by calculating the determinant of the matrix
|A| = -1/2 * -1 - 3 * -1
Evaluate
|A| = 7/2
To calculate x, we replace the first column by the last.
So, we have:
[tex]\left[\begin{array}{cc}-4&3\\-1&-1\end{array}\right][/tex]
Next, calculate the determinant of the matrix
|x| = -4 * -1 - 3 * -1
|x| = 7
The value of x is then calculated as:
x = |x|/|A|
This gives
x = 7 ÷ 7/2
Evaluate
x = 2
Hence, the value of x is 2

A shipping container will be used to transport several 40-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 23000 kilograms. Other shipments weighing 7800 kilograms have already been loaded into the container.
The question is incomplete. The complete question is :
A shipping container will be used to transport several 40-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 23000 kilograms. Other shipments weighing 7800 kilograms have already been loaded into the container. Which inequality can be used to determine cc, the greatest number of 80-kilogram crates that can be loaded onto the shipping container?
Solution :
Given data :
Weight of the crate = 40 kg
Greatest weight that the container can load = 23000 kg
Weight of the other shipments on the container = 7800 kg
So the greatest number of 40 kg crates = c
Therefore, the weight of the other shipment + weight of crate x number of crates ≤ greatest weight of the container
7800 + (40 x c) ≤ 23000
7800 + 40c ≤ 23000
40c ≤ 23000 - 7800
40c ≤ 15200
c ≤ 380
Hence, the maximum number of 40 kg crate is 380.

Answer:
a) Only the first one is an identity.
Step-by-step explanation:
1). 8 cos O tan O csc O = 8 simplifies to:
cos O tan O csc O = 1
cos O * (sin O / cos O) * (1 /sin O)
= cos O sin O / cos O sin O
= 1
So it is identity.
2) 13 sec^2 O/ cos^2 O - tan^2 O / cos^2O
= 13 sec^2 O - tan^2 O / cos^2 O
Now sec^2 O = 1 + tan^2 O, so we have:
(13( 1 + tan^2 O) - tan^2 O) / cos^2 O
= (12 tan^2 O + 13) / cos^2 O
This is not always = 2 so its not an identity.

What is the slope-intercept form?In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;
y = mx + c
Where:
m represent the slope or rate of change.x and y are the points.c represent the y-intercept or initial value.Based on the information provided above, a linear equation that models the situation with respect to the rate of change is given by;
y = mx + c
y = 20x - 80
In conclusion, we can logically deduce that the slope is equal to $20 while the y-intercept is $80.

Stefanie bought a package of pencils for $1.75 and some erasers that cost $0.25 each. She paid a total of $4.25 for these items.
Answer:
Stefanie bought 10 erasers.
Step-by-step explanation:
Stefanie bought a package of pencils for $1.75 and some erasers that cost $0.25 each. She paid a total of $4.25 for these items.
Beind "x" be the number of erasers bought, you can express Stepanie's purchases by the equation:
1.75 + 0.25*x = 4.25
Solving:
0.25*x = 4.25 - 1.75
0.25*x = 2.5
x= 2.5÷ 0.25
x=10

M mrs. Gallegos Burns 236 calories riding her bike each hour she wants to burn more than 590 calories riding her bike at the same rate which inequality represents all possible values for teeth and number of hours mrs. Vehicles must ride her bike to burn more than 590 calories
Answer: x > 2.5
Step-by-step explanation:
Since Mrs Gallegos burns 236 calories riding her bike each hour and she wants to burn more than 590 calories riding her bike at the same rate, the inequality that will represent the number of hours that she will use will be:
x > 590/236

Please help am gonna get an F
Answer:
2w + 2L is the answer I think, but see the discussion below.
Step-by-step explanation:
There are three possibilities.
One
| = 1
so you get 1 + w + 1 + w = 2 + 2w
Two
l = L
l + w + l + w
So you get 2l + 2w. Since the l is so confusing, I normally use L for l. It's not very pretty but it does work
In this instance, you would get 2L + 2w
Three
| could be an absolute value signal. If that is the case, you should use abs(+w+)
Of the three, I think two is what you intended.
