A worker is stacking boxes.One stack has boxes that are 2 inches high. The other stack has boxes that are 5 inches high. At what height will the two stacks of boxes be equal in height?
Answers
Answer:
10 inches.
Step-by-step explanation:
One stack has boxes that are 2 inches high, then the height of this stack can be only multiples of 2 inches.
The other stack has boxes that are 5 inches high, then the height of this stack can be only multiples of 5 inches.
The height of both stacks will be the same for all the common multiples of 2 and 5.
Because 2 and 5 are prime numbers, all the common multiples between 2 and 5 will be direct products of these two numbers.
Like 2*5 = 10
is both a multiple of 2 and 5 (is the first common multiple)
Then we can use stacks of 10 inches.
Such that, for the stack where each box is 2 inches high, we need:
10in/2in = 5
5 boxes.
And for the stack where each box is 5 inches high, we will need:
10in/5in = 2
2 boxes.

A soccer player uses her head to hit a ball up in the air from a height of 2 meters with an initial vertical velocity of 5 meters per second. The height h in meters of the ball is given by \large h=-4.9t^2+5t+2 , where t is the time elapsed in seconds. How long will it take the ball to hit the ground if no other players touch it?
Answers
Answer:1.32 s
Step-by-step explanation:
Given
The initial height of ball H=2 m
Initial velocity u=5 m/s
Height of ball at any instant is given by
[tex]H=-4.9t^2+5t+2[/tex]
The ball will hit the ground when h=0
[tex]-4.9t^2+5t+2=0\\4.9t^2-5t-2=0\\t=\dfrac{5\pm\sqrt{25+4(4.9)(2)}}{2\times 4.9}\\t=\dfrac{5\pm\sqrt{64.2}}{9.8}\\t=\dfrac{5+8.01}{9.8}=1.32\ s\quad\text{Neglecting negative value of t}[/tex]

We conclude that the area of the right triangle is:
[tex]A\:=p^2-2p-3[/tex]
Hence, option A is correct.
Step-by-step explanation:
From the given right-angled triangle,
Base = p+1Perpendicular = 2p-6Using the formula to determine the area of the right-angled triangle
Area of the right triangle A = 1/2 × Base × Perpendicular
[tex]=\frac{1}{2}\left(p+1\right)\left(2p-6\right)[/tex]
Factor 2p-6: 2(p-3)
[tex]=\frac{\left(p+1\right)\times \:2\left(p-3\right)}{2}[/tex]
Divide the number: 2/2 = 1
[tex]=\left(p+1\right)\left(p-3\right)[/tex]
[tex]\mathrm{Apply\:FOIL\:method}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]

[tex]=pp-3p+1\cdot \:p-1\cdot \:3[/tex]
[tex]=p^2-2p-3[/tex]
Therefore, we conclude that the area of the right triangle is:

Step 1: Define
5 - 7(2 - x) = 31 - 4(2x - 5)
Step 2: Solve for x
Distribute: 5 - 14 + 7x = 31 - 8x + 20Subtract/Add: -9 + 7x = -8x + 51Add 8x on both sides: -9 + 15x = 51Add 9 to both sides: 15x = 60Divide 15 on both sides: x = 4Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5 - 7(2 - 4) = 31 - 4(2(4) - 5)(Parenthesis) Multiply: 5 - 7(2 - 4) = 31 - 4(8 - 5)(Parenthesis) Subtract: 5 - 7(-2) = 31 - 4(3)Multiply: 5 + 14 = 31 - 12Add/Subtract: 19 = 19Here we see that 19 does indeed equal 19.
∴ x = 4 is the solution to the equation.
Anna and Jose bought a pizza and ate 5 of the 8 slices. Zach and Sarah came over and Anna split the remaining slices evenly between them. How would you determine the fraction of the original pizza that Zach and Sarah each ate?
Answers
Answer:
24/2 slices
= 12/1
Step-by-step explanation:
Total slices of pizza = 8
Anna and Jose ate = 5
Slices of pizza remaining = 3
Zach and Sarah came over and Anna split the remaining slices evenly between them
That's is, 3 slices of pizza divided by 2 people
= 3/2
= 1 1/2 slices each
Each of Zach and Sarah ate 3/2 slices of pizza
fraction of the original pizza that Zach and Sarah each ate
= 3/2 of 8
= 3/2 × 8
= 24/2
= 12/1

Work out the perimeter
Answers
Answer: The shape below is formed from a rectangle measuring 18 cm by 24cm from which a rectangle of length 8.6cm has been removed
Step-by-step explanation:
initial Perimeter of rectangle = 2 (24 + 18) = 84 cm
After removing rectangle of length 8.6 cm
two sides of 8.6 cm are added in perimeter
Perimeter of Shape
= 2 (24 + 18) + 8.6 + 8.6
= 84 + 17.2
= 101.2 cm
perimeter of the shape = 101.2 cm

Answers
Answer:
Linear measures (measures of length and width) are at a scale of 1:500; or
for every "real life" yard, the map would be "1/500" yard long.
Thus for measures of area, such as hectares, the map would would be 1/(500)² as big.
So: (3/5 = .6) hectares would be .6/(500)² hectares = .0000024 hectares.
And since 1 hectare = 15500031 in²;
the area on the map would be 15500031 (.0000024) in² ~ 37.2 in² ~ 240 cm²
what is the dividend yield on Stock A that sells 15$/share, when company A pays a quarterly dividend of $0.15 per share
Answers
Answer: The dividend yield on Stock A = 0.04
Step-by-step explanation:
Given: quarterly dividend = $0.15 per share
Annual dividend per share = 4 x 0.15 = $0.6 [1 year = 4 quarters]
Stock's price per share = $0.15
The computation of dividend is given by :-
Dividend yield = (annual dividend per share) divided by (the stock's price per share).
Here, Dividend yield = (0.6) ÷ 15 = 0.04
Hence, the dividend yield on Stock A = 0.04

2x-4y=14
3y+5x=9
Answers
Answer:
x=3, y=-2
Step-by-step explanation:
If 2x-4y=14, then we know that 2x=14+4y. This means that x=7+2y. If we substitute this into the next equation we get: 3y+(35+10y)=9. This means that we have 35+13y=9. If we subtract 35 from both sides we get 13y=-26. This means y=-2. If you subsitute this in the first equation, we have 2x--8=14. -- means + so you do 2x+8=14. This means that x=3.

Jerry was given some birthday money. He puts the money in an account. Every month after that, he deposits the same amount of money.
The equation that models this situation is y = 50x + 75, where y is the amount of money in the account and x is the number of deposits.
What does the y-intercept mean in this situation?
A. He was given $50 for his birthday.
B. He puts $75 in the account each month.
C. He puts $50 in the account each month.
D. He was given $75 for his birthday.
Answers
The y -intercept in this situation mean that Jerry was given $75 for his birthday
The equation below is a linear equation.
y = 50x + 75
A linear equation is an equation that has a single variable raised to the power of 1. 50x is raised to the power of 1
75 represents the constant. This is the money he deposited in the account. 75 is the y-intercept. The y-intercept is the value of the line y when it crosses the y-axis
50x is the slope of the line. - 50 is the amount he puts in every month and x represents month.
The slope of a line also known as the gradient of the line determines the steepness and direction of a line. If the slope coefficient is less than zero, the slope is negative and it would decline from left to right
y is the dependent variable. It is the total amount he would have at the end of each month. y depends on the constant term (75), the number of months(x) and the amount he deposits every month (50)
at the end of :
one month, he would have : 50(1) + 75 = 125
two months, he would have : 50(2) + 75 = 175
