49 Jessica skated 4 laps in 82 seconds. Which of the following is an equivalent rate of skating??A6 laps in 120 secondsB10 laps in 205 secondsC 6 laps in 130 secondsD10 laps in 215 seconds
Answers
ANSWER
B. 10 laps in 205 seconds
EXPLANATION
If we write the rate of laps to seconds as a fraction we have:
[tex]\frac{4}{82}=\frac{2}{41}[/tex]I simplified the fraction and got 2/41. An equivalent rate must give the same simplified fraction. For option B:
[tex]\frac{10}{205}=\frac{2}{41}[/tex]We can reduce both rates to the same rate: 2 laps every 41 seconds. Therefore, these two rates are equivalent.

Answer: 9 inches
Step-by-step explanation:
We know that the area of a square can be solved with the following formula when s is the length of one side. We will plug in our known values and solve:
a = s²
(81) = s²
[tex]\sqrt{81}[/tex] = s

which equation represents the lines through (2, -4) and (0, 4)?
Answers
The equation that represents the lines through (2, -4) and (0, 4) is y = -4x + 4
How to determine the equation of the lineIt is crucial to note that the equation of a line is expressed as;
y = mx+ c
Where;
y is a point of the distance on the y-axisx is a point of the distance on the x-axism is the slope or gradient of the linec is the intercept of the line on the y-axisFrom the information given, we have the point as;
(2, -4) and (0, 4)
Now, let's determine the slope
The formula for determining the slope or gradient of a line is expressed as;
Slope, m = y2 - y1/x2 - y1
Now, substitute the values into the formula
Slope, m = 4 -(-4)/0 -2
expand the bracket
Slope, m = 4 + 4/-2
Add the values
Slope, m = 8/-2
Slope, m = -4
To determine the intercept, use the points of x and y
-4 = -4(2) + c
expand the bracket
-4 = -8 + c
c = -4 + 8
c = 8
The equation of the line is;
y = -4x + 4
Thus, the equation of the line is y = -4x + 4

Maran is selling candy apples at a fund-raiser for a charity. She made 160 candy apples and spent $120 on ingredients and supplies. She sold all the candy apples for $480.
Select TWO statements that are true.
A.Maran spent $3 on each candy apple.
B.Maran spent $0.75 on each candy apple.
C.Maran sold each candy apple for $4.
D.Maran earned a profit of $3 on each candy apple sold.
E.Maran sold each candy apple for $3.
Answers
If Maran made 160 candy apples, spending $120 on ingredients and supplies while selling all the candy apples for $480, then the two statements that are true are:
B. Maran spent $0.75 on each candy apple (Cost Price), and
E. Maran sold each candy apple for $3 (Selling Price).
As per the question statement, Maran made 160 candy apples, spending $120 on ingredients and supplies while selling all the candy apples for $480.
We are required to identify the two true statements from a the set of 5 statements, provided in the question itself, related to the per candy cost price, sell price and profit of Maran.
Since he made 160 candy apples, spending $120 on ingredients and supplies, therefore, the cost price of per candy will be $(120/160) = $0.75, i.e., Statement B that Maran spent $0.75 on each candy apple is True.
Also, he sold all 160 candies for a total of $480, therefore, the sell price of each candy is $(480/160) = $3. Hence, Statement E that Maran sold each candy apple for $3., is also true.
Now, since the cost price of each candy is $0.75 and the sell price of the same is $3, then Maran made a profit of $(3 - 0.75) = $2.25 per candy. But statement D mentions that Maran earned a profit of $3 on each candy sold, which is false.
Cost Price: It is the price at which, an object or commodity is manufactured or bought at, by the retailer.Selling Price: It is the price at which, the commodity is sold by the retailer, and if the selling price is higher than the cost price, the retailer is said to earn a profit, while in the opposite case, the retailer is said to incur a loss.To learn more about Cost Prices & Selling Prices, click on the link below.

A rental company rents a luxury car at a daily rate of $38.48 plus $.50 per mile. Paul is allotted $110 for car rental each day. Write an equation to represent the cost C of renting a car and driving x miles.
How many miles can Paul travel on the $110?
Answers
Answer:
C=38.48+0.5x
about 143 miles
Step-by-step explanation:
$38.48 base cost plus $.50 per mile, so after x miles, it would be 0.5x
so C=38.48+0.5x
to find how many miles Paul can travel
we set 110=38.48+0.5x
then solve
x=143.04
so Paul can travel about 143 miles

B)x < 0 or x > 8
C)0 < x < 8
D)–1 < x < 4
Answers
The solution to the inequality |2x - 3| > 5 is: x < -1 or x > 4
Therefore, the correct option is A) x < -1 or x > 4.
Given that we need to find the solution to the inequality |2x – 3| > 5
To solve the inequality |2x - 3| > 5, we can break it down into two cases:
Case 1: 2x - 3 > 5
In this case, we have:
2x - 3 > 5
2x > 5 + 3
2x > 8
x > 4
Case 2: -(2x - 3) > 5
In this case, we have:
-(2x - 3) > 5
-2x + 3 > 5
-2x > 5 - 3
-2x > 2
x < -1 (remember to reverse the inequality when multiplying or dividing by a negative number)
Combining the solutions from both cases, we find that the solution to the inequality |2x - 3| > 5 is:
x < -1 or x > 4
Therefore, the correct option is A) x < -1 or x > 4.

HELP thanks and 5 stars to the best answer. Enter the value of the smiley face?
Answers
The value of the smiley face given the values of the rectangle, triangle and star is 908.
What is the value of the smiley face ?In order to solve this question, take note of the BODMAS rule. The BODMAS rule gives the order in which mathematical operations should be solved.
B - bracket O - of D - division M - multiplication A - addition S - subtractionThe value of the rectangle would be determined first using the third equation provided in the question. let a represent the value of a rectangle.
(4 x a) + (2 x a) - (3 x a) = 15
4a + 2a - 3a = 15
3a = 15
a = 15 / 3
a = 5
The next step is to determine the value of the triangle. The second equation would be used. Let b represent the value of the triangle.
(3 x 5) + (4 x b) = 47
15 + 4b = 47
4b = 47 - 15
4b = 32
b = 32 / 4
b= 8
Now, determine the value of the star using the first equation. Let the value of the star be represented with c.
5 + (3 x 8) - c = 17
5 + 24 - c = 17
29 - c = 17
c = 29 - 17
c = 12
Now, the value of the smiley face can be determined using the last equation:
12 x (8 + 12 - 5) + 8(8 . 12 - 5)
12 x (15) + 8(91)
180 + 728 = 908

The equation of line in slope intercept form can be written as y = mx + c where m is the slope of line and c is the y intercept.
We are given three equations namely y = 2x -2, y = -x + 1 and y = x - 4 and we need to determine the description of equation, slope and y intercept. The equation y = 2x - 2 is the equation of straight line. If we compare this equation with the slope intercept form of line then, m = 2 and c = -2. Thus, slope is 2 and y intercept is -2. The equation y = -x +1 is the equation of straight line. If we compare this equation with the slope intercept form of line then, m = -1 and c = 1. Thus, slope is -1 and y intercept is 1. This equation y = x - 4is the equation of straight line. If we compare this equation with the slope intercept form of line then, m = 1 and c = -4. Thus, slope is 1 and y intercept is -4.

Under these conditions, can the carpenter complete his work? Rounded to the nearest tenth, how far up the wall does the ladder reach?
Answers
The carpenter will not be able to complete his work because the ladder reach 14.1 ft up the wall.
In this question, we have been given a carpenter has a 15 foot ladder. For safety, the bottom of his ladder must be placed 5 feet from the wall.
Consider the following diagram.
In right triangle ABC, AC represents the length of the ladder, CB is the distance between wall and the bottom of the ladder.
Using Pythagoras theorem,
AC² = AB² + BC²
15² = 5² + AB²
225 - 25 = AB²
AB = √200
AB = 14.1 ft ............(1)
We have been given that in order to complete his work, the ladder must reach 14.5 feet up the wall.
From (1), we can see that the ladder will reach 14.1 ft up the wall.
