Answer:
She lands on 92.
Step-by-step explanation:
92=58+2+30+2
where she lands = 58+34
92 = 58 + 2x + y where x=2 and y=32
Final answer:
Sally started on square 58 and used three cards with values of +2, +30, and +2, respectively. The equation for her moves is 58 + 2 + 30 + 2, which equals 92. Hence, she landed on square 92.
Explanation:
Sally's game piece was initially on square 58. To find out where she landed after using her cards, we can write an equation that adds the values on the cards to her starting position. Sally played three cards with the following values: +2, +30, and +2.
The equation to show Sally's moves is:
Starting position + first card + second card + third card = new position
58 + 2 + 30 + 2 = new position
Now, let's calculate the total:
58 + 2 = 60
60 + 30 = 90
90 + 2 = 92
Therefore, Sally's new position after using all her cards is on square 92.

(5b^2-3b+2)+(2b-4)
Answer:
5b²-1b-2
Step-by-step explanation:
-3b and +2b are like terms so you combine them together -3b+2b= -1b
+2 and -4 are like terms so +2-4= -2
5b² has no like terms
then you put your answers together to simplify the equation
5b²-1b-2
The polynomials added together give the result 5b^2 - b - 2. The addition is done by combining like terms in the given polynomials.
Explanation:To add these polynomials, you combine like terms. Like terms are the terms in the polynomial that have the same variable and exponent. Here, our terms are 5b^2, -3b, 2, 2b, and -4.
The term 5b^2 does not have a like term, so it remains as is. The terms -3b and 2b add up to -b because -3b + 2b = -b. And finally, the constants 2 and -4 add up to -2. When we combine these results, we have the final answer: 5b^2 - b - 2.

using standard normal distribution tables, the area under the standard normal curve corresponding to Z > -1.62 is:
The area under the standard normal curve corresponding to Z > -1.62 is approximately 0.9474.
Explanation:The question asks for the area under the standard normal curve corresponding to Z > -1.62. Using standard normal distribution tables, we can find this area by finding the area corresponding to Z = -1.62 and subtracting it from 1. Since standard normal distribution tables provide the area to the left of the Z-score, we need to subtract the area from 1 to get the area to the right of the Z-score.
By looking up Z = -1.62 in the standard normal distribution table, we find the area to the left (or below) the Z-score is approximately 0.0526. Therefore, the area to the right (or above) the Z-score is approximately 1 - 0.0526 = 0.9474.

As a first step in solving the system shown, Yumiko multiplies both sides of the equation 2x – 3y = 12 by 6. By what factor should she multiply both sides of the other equation so that she can add the equations and eliminate a variable? What one-variable equation is she left with after adding?
5x + 6y = 18
2x – 3y = 12
Factor:________
Equation:________x=_________
Answer:
Yumiko should multiply the other equation by 3.
If she adds the two equations she would be left with the variable 'x'.
Step-by-step explanation:
Given the two equations are as follows:
[tex]$ 2x - 3y = 12 \hspace{5mm} \hdots (1) $[/tex]
[tex]$ 5x + 6y = 18 \hspace{5mm} \hdots (2) $[/tex]
It is given that she multiplies the first equation by 6. Therefore, (1) becomes
[tex]$ 12x - 18y = 72 \hspace{15mm} \hdots (a) $[/tex]
Now, note that the sign of the variable 'y' is negative. So, if we make the co-effecient of 'y' equal in both the cases, add them it would result in the elimination of the variable 'y'.
The co-effecient of y in Equation (2) is 6. To make it 18 like it is in Equation (1), we multiply throughout by 3.
Therefore, Equation (2) becomes:
[tex]$ 15x + 18y = 54 \hspace{5mm} \hdots (b) $[/tex]
Now, we add Equation (a) and Equation (b).
[tex]$ \implies 12x - 18y + 15x + 18y = 72 + 54 $[/tex]
[tex]$ \implies 27x = 126 $[/tex]
Factor: 3
Equation: 27x = 126

a hose is coiled into circular loops about 30 inches in diameter. the length of each loop is about...
a. 7 ft
b. 8 ft
c .9ft
D. 10ft
Answer:
b. 8 ft
Step-by-step explanation:
We use the formula for the circumference of a circle to find the length of each loop.
Circumference of a circle = 2πr or Dπ
Where: π = pi
r = radius of the circular loops
D = Diameter
π = [tex]\frac{22}{7}[/tex]
D = 30 inches
Use Circumference of a circle = Dπ
Circumference of a circle = 30 x (22/7)
= 30 x 3.142857143
= 94.28571429 inches
Convert 94.28571429 inches to feet (ft)
12 inches = 1 ft
94.28571429 inches = 94.28571429/12
= 7.857142858 ft

if y=-6.6 when x=9.9, find y when x=6.6
y=?
Answer:
y = - 4.4
Step-by-step explanation:
from the question
y = -6.6
x = 9.9
y∝ x
y = kx ..... where k is introduced as a constant of proportionality
solve for k
y=-6.6 and x = 9.9
we have,
-6.6 = k × 9.9
-6.6 = 9.9k
divide both sides by 9.9
-6.6/ 9.9 = 9.9k/9.9
-0.667= k
therefore k = - 0.667
now, find y when x = 6.6
from the equation y = kx
y = -0.667 × 6.6
y = - 4.4
Answer:
-4.4
Step-by-step explanation:
x : y
9.9 : -6.6
6.6 : y
9.9/-6.6 = 6.6/y
y = 6.6 × -6.6/9.9
y = -4.4

The height y of a jumping frog can be modeled by y = -16x^2+ 4x, where x is the time in
seconds) since the frog jumped from the ground. Find the roots of the equation when y = 0
Explain what the roots mean in this situation.
Answer:
roots: 0, 1/4time when the height is zeroStep-by-step explanation:
The roots are the values of x that make y=0.
0 = -16x^2 +4x = -4x(4x -1)
The values of x that make the factors zero are solutions to this equation:
x = 0
x = 1/4 . . . . . makes the factor (4x-1) equal to zero
The roots of the equation are x=0 and x=1/4.
__
Since y is height and x is time, when y=0, the frog is on the ground. The roots, then, are the times when the frog is on the ground.
The smaller root is the time when the frog leapt.
The larger root is the time when the frog landed.
The roots of the equation y = -16x² + 4x are x = 0 and x = 1/4,
The given equation y = -16x² + 4x models the height y of the frog as a function of time x in seconds.
To find the roots of this equation when y = 0, we need to solve:
0 = -16x² + 4x
This is a quadratic equation.
Quadratic equations can be solved by factoring, completing the square, or using the quadratic formula.
In this case, factoring is straightforward:
0 = x(-16x + 4)
This gives us two solutions
x=0
x=4/16=1/4
The roots are x = 0 and x = 1/4 seconds.
Interpreting the Roots
The roots of the equation indicate the times when the frog is at ground level (y = 0). At x = 0, the frog has just jumped, and at x = 1/4 seconds, the frog returns to the ground. Therefore, these roots represent the start and the end of the jump respectively.What does 7 1/2 - 2 3/16 - 1 5/8= as a fraction?

Tim would like to buy a video game that costs $27. He has not saved any money. His parents are willing to pay him $3 for every 2 chores, but will also pay him for completing single chores.
Tim would have to do 18 chores (2 chores 9 times or 1 chore 18 times) to be able to buy the video game.
Step-by-step explanation:
Step 1; Tim's parents will give him $3 for every two chores. This equals $1.50 for a single chore. He wants to save up $27 so that he can buy the video games he wants.
Step 2; The number of times he has to do the chores to be able to but the video game is a division between the money he wants to save up by the money he gets for the chores.
Number of 2 chores he needs to do = Amount of money he wants to save up / money he gets for doing two chores
= $27 / $3 = 9 times.
Number of single chores he has to do =Amount of money he wants to save up / money he gets for doing two chores
$27 / $1.50 = 18 times

The height of the living room ceiling is 15 feet.
Explanation:To find the height of the living room ceiling, we can start by letting 'x' represent the height of the living room ceiling.
Since the bedroom ceiling is 2/3 as high as the living room ceiling, we can write the equation:
10 = (2/3)x
To solve for x, we can multiply both sides of the equation by 3/2:
(3/2)(10) = (3/2)((2/3)x)
15 = x
Therefore, the height of the living room ceiling is 15 feet.
