The answer to the given questions are b = 54, c = 24, m = 75, y = 33, p =87.
What happens to a number or a variable when it is being moved from one side of the equation to the other side ?It changes it's sign.
We have to form equation for the given questions with a variable and find the value of the variable.
In the first question
There were 45 apples in the barn her dad picked some more apples and put them into it and now the total no. of apples in the barn is 99.
Assuming here dad picked b no. of apples the the equation will be of the form
45 + b = 99
b = 99 - 45
b = 54.
∴ Her dad put 54 apples in the barn.
In the second question
Gran sold 13 clothes in the sell and after that she had 11 clothes left and c is the total no. of clothes
∴ c = 13 + 11
c = 24
So Gran knitted 24 clothes for her school fundraiser.
In the third question
leah's friend gave her 12 dollars for her birthday and after her grandparents gave her some money (m) she had a total of
87 dollars.
∴ 12 + m = 87
m = 87 - 12
m = 75
So her grandparents gave her 75 dollars of money.
In the fourth question
Lorenzo had 96 passing yards before the football game and after that he had 129 yards for the season and y be the no. of passing yards during the football game.
∴ 96 + y = 129
y = 129 - 96
y = 33.
So he made 33 passing yards during the game.
In the fifth question
An artist took 105 art pieces and after he sold some of them which is p he is left with 18 pieces
∴ 105 - p = 18
p = 105 - 18
p = 87
So he sold 87 pieces of art in the fair.

40 facts increased to 56. What is the percent increase?
Step-by-step explanation:
40 increases to 56.
To find the percent increase:
Subtract the increased value from the original value.
Divide the difference by the original value.
Multiply the quotient by 100 to represent the percent.
Solve:
[tex]56 - 40 = 16[/tex]
[tex]16 \div 40 = 0.4[/tex]
[tex]0.4 \times 100 = 40[/tex]
There's a 40% increase.

Use a net to find the surface area of the right triangular prism shown:
Answer:
256 ft²
Step-by-step explanation:
Net comprises: 2 equal triangles, 2 equal rectangles and 1 smaller rectangle
Area of a triangle = 1/2 x base x height
⇒ area of one triangle = 1/2 x 10 x 7 = 35 ft²
Area of a rectangle = width x length
⇒ area of larger rectangle = 6 x 12 = 72 ft²
⇒ area of smaller rectangle area = 6 x 7 = 42 ft²
⇒ Total area = (2 x 35) + (2 x 72) + 42 = 256 ft²
Can someone explain the three solutions in math: one solution, no solution, and all real numbers please. What does it mean when then the statement is false how do I know when it’s false?I’m confused I don’t know how to identify the solutions please help me thank you so much!!!
Step-by-step explanation:
Note that when lines intersect, that when they show a solution.
All Solutions:
When we graph two equations, and they line on the same curve thus all points will be a point of intersection..
Let say we have two linear equations.
[tex]4x + 4y = 16[/tex]
[tex]x + y = 4[/tex]
This are all solutions, because
if we do the graphical way, when we graph this on a calculator or desmos, they will lie on the same curve so it has infinite points of intersections.
If we do algebraic way,
Notice that the top equation is the same as The bottom equation but just multiplied by 4. So the top and bottom equations are the same.
So whenever the two or more equations have same slope and same y intercept, the solutions will be all real solutions or infinite solutions.
One Solution:
In plane geometry, note that a line that isn't parallel to another one, will intersect eventually once.
This means that for example
[tex]4x + 4y = 16[/tex]
[tex]x + 2y = 32[/tex]
These equations have different slope so they will intersect once. Which means it'll have one solution.
NO Solutions:
Parallel Lines never intersect which means they have no solutions.
Consider this
[tex]4x + 4y = 16[/tex]
[tex]x + y = 1[/tex]
We know the slopes are the same but y intercept is different they will never intersect.
Given a function described as the equation y = 4x - 4, what is y when x is 1, 2, and 3?
27 is 30% of what number?
Answer:
im pretty sure that the answer your looking for is 90
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
STEP 1 27 = 30% × Y
STEP 2 27 = 30/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 30 we will arrive at:
STEP 3 Y = 27 × 100/30
STEP 4 Y = 27 × 100 ÷ 30
STEP 5 Y = 90
Finally, we have found the value of Y which is 90 and that is our answer.

It's biased because they're only asking people standing in the lunch line, instead, they should be asking numerous of students randomly to eliminate biased.
8) Use the slope formula to find the slope between
the points: (-1,2) and (3,- 3)
m =
Answer:
-5/4
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -3 -2)/( 3 - -1)
= ( -3-2 ) /( 3+1)
= -5/4
Answer:
m = -5/4
Step-by-step explanation:
The slope formula is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]\frac{(-3)-(2)}{3-(-1)}[/tex] [tex]\frac{-5}{3+1}[/tex] [tex]\frac{-5}{4}[/tex]Therefore, m = -5/4.

What is the slope and y- intercept for -10x+3y-6=10
Answer:
Slope = m = 10/3 and y-intercept = (0, 16/3)
Step-by-step explanation:
-10x + 3y - 6 = 10
3y = 10x + 16
y = 10/3x + 16/3
Slope = m = 10/3

3. volume of the rice container is 1.5 times the volume of the sugar container
4. 50.24 in³
5. Rice container has the greatest volume
Flour container has the smallest volume
Step-by-step explanation:
By inspection of the diagram, the three containers are all cylinders.
Volume of a cylinder = [tex]\pi r^2h[/tex]
(where r is the radius and h is the height)
Given [tex]\pi[/tex] = 3.14
1. volume of sugar container = 3.14 x 2.5² x 8 = 157 in³
2. 235.5 = 3.14 x 2.5² x h
⇒ 235.5 = 19.625h
⇒ h = 235.5 ÷ 19.625 = 12 in
3. height of sugar container = 8 in
height of rice container = 12 in
12 ÷ 8 = 1.5
⇒ height of rice container is 1.5 times the height of the sugar container
volume of sugar container = 157 in³
volume of rice container = 235.5 in³
235.5 ÷ 157 = 1.5
⇒ volume of the rice container is 1.5 times the volume of the sugar container
4. volume of flour container = 12.56 x 4 = 50.24 in³
5. volume of sugar container = 157 in³
volume of rice container = 235.5 in³
volume of flour container = 50.24 in³
Rice container has the greatest volume
Flour container has the smallest volume

Consider the series.
∞∑n=1 (3^n+1 / 3n+1)
Does the series converge or diverge?
Select answers from the drop-down menus to correctly complete the statements.
Put 1
[tex]\\ \rm\Rrightarrow \left(\dfrac{3^{1+1}}{3(1)+1}\right)[/tex]
[tex]\\ \rm\Rrightarrow 3^2/4=9/4=2.2[/tex]
Put 2
[tex]\\ \rm\Rrightarrow \left(\dfrac{3^{2+1}}{3(2)+1}\right)=3^3/7=27/7=3.8[/tex]
R is
3.8/2.2=19/11Its greater than 1 .
So diverge series.Answer:
[tex]r=\dfrac{12}{7}[/tex]
series diverges
Step-by-step explanation:
To find the common ratio (r) of a geometric series, divide the (n+1)th term by the nth term.
When n = 1:
[tex]a_1=\dfrac{3^{1+1}}{3(1)+1}=\dfrac{3^2}{4}=\dfrac94[/tex]
When n =2:
[tex]a_2=\dfrac{3^{2+1}}{3(2)+1}=\dfrac{3^3}{7}=\dfrac{27}{7}[/tex]
Therefore,
[tex]r=\dfrac{a_2}{a_1}=\dfrac{\frac{27}{7}}{\frac{9}{4}}=\dfrac{12}{7}[/tex]
A series that converges has a finite limit. If |r| < 1, then the series will converge.
A series that diverges means either the partial sums have no limit or approach infinity. If |r| > 1 then the series diverges.
Therefore, as the limit of the series approaches infinity and it's r value is greater than 1, the series diverges.

A researcher is interested in determining if a psychic really has power to predict. The researcher takes four cards, each of a different type: king, queen, jack, and ace. After mixing up the cards many times and he selects one card without showing the psychic. The researcher asks the psychic which card was selected. The researcher records if the psychic was correct or not. The researcher does this two hundred times. If the psychic really has special abilities then he should pick the correct card more often then if it was by chance alone. The researcher is interested in determining if the card was identified correctly significantly more often then chance would suggest. What would be the null and alternative hypothesis for this case
It can be deduced that the null hypothesis is H: p = 0.25 and the alternative hypothesis is H: p > 0.25.
What is the null hypothesis?It should be noted that null and alternate hypothesis are written based on the population parameter.
From the information given, the claim is that they card was identified significantly more than chance would suggest. The proportion of card selected will be:
= 1/4 = 0.25
Therefore, the null hypothesis is H: p = 0.25 and the alternative hypothesis is H : p > 0.25.
