Here, we want to select the inequality that best represents the situation
Let the number of weeks be x
Total value saved in x weeks at $35 per week will be 35 * x = 35x
Adding this to what she had initially, the total expression becomes 35x + 45
This sum must be the same or greater than what she plans to save
The inequality is thus;
[tex]35x\text{ + 45}\ge\text{ 375}[/tex]find the measure of each angle. JKL=5x+4 and LKM=3x
Angle JKL has a measure of 24 degrees while angle LKM has a measure of 12 degrees
How to determine the measure of each angle?The possible question is added at the end of the solution and as an attachment
From the attached figure, we have the following angles
Angle 1: Angle JKL = 5x+4Angle 2: Angle LKM = 3xFrom the attached figure, we can see that:
Angle 1 is twice the measure of angle 2
This is so because, the angle 1 is the vertex angle of an isosceles triangle
While the angle 2 is half of it
So, we have
Angle 1 = 2 * Angle 2
Substitute the known values in the above equation
So, we have
2 * 3x = 5x + 4
Evaluate the product
So, we have
6x = 5x + 4
Evaluate the like terms
x = 4
Substitute x = 4 in the equations JKL=5x+4 and LKM=3x
So, we have
JKL= 5 x 4 + 4
LKM = 3 x 4
Evaluate the equations
So, we have
JKL= 24
LKM = 12
Hence, the measures of the angles are JKL= 24 and LKM = 12, respectively

A store sold 14 more colored shirts than white shirts. The white shirts cost $9.95, and the colored shirts cost $10.50. The store sold $310.60 worth of shirts.
How many of each type of shirt were sold?
A store sold 22 colored shirts and 8 white shirts.
Let x be the number of colored shorts and y be the number of white shirts.
A store sold 14 more colored shirts than white shirts.
so, we get an equation,
x = y + 14 ....................(1)
The white shirts cost $9.95, and the colored shirts cost $10.50. The store sold $310.60 worth of shirts.
So we get an equation,
10.50x + 9.95y = 310.60 .............(2)
Substitute above value of x in equation (2)
10.50(y + 14) + 9.95y = 310.60
10.50y + 147 + 9.95y = 310.60
20.45y = 310.60 - 147
20.45y = 163.6
y = 8
Substitute above value of y in equation (1)
So, x = 8 + 14
x = 22
Therefore, a store sold 22 colored shirts and 8 white shirts.

The cost to travel X miles east or west on a train is the same. The function for the cost
c(x) = 0.75|x| + 25.
Describe how c(x) is related to its parent function and interpret the function in the context of the situation.
C(x) is related to its parent function c(x) = 0.75|x| + 25.
The function in the context of the situation illustrated that the cost is the same.
How to illustrate the information?It should be noted that a function is used to show the relationship between the variables.
In this case, the cost to travel X miles east or west on a train is the same. The function for the cost is given as c(x) = 0.75|x| + 25.
Let East = positive direction
Let West = negative direction
Let the travel distance in East = x
Travel distance for West = -x mile
The cost to travel East x miles will be:
= 0.75(x) + 24
= 0.75x + 25
The cost to travel West will be:
c(-x) = 0.75x + 25
This shows that the cost will be the same even though there in different directions.

Carlos is baking a pie with a circumference of 56 inches. What is the area of the pie he will bake?
the area of the pie that Carol will bake will be equal to 249.51 inches².
We are given the circumference of the pie as = 56 inches.
As pie is in the shape of a circle, we will use the formula for circumference to find the radius of the circle.
2 π r = 56 inches
2 × 22 / 7 × r = 56
r = 56 × 7 / ( 22 × 2)
r = 8.91 inches.
Area of circle is given by:
π r²
Substituting the values in the formula, we get that
A = 22 / 7 (8.91)²
A = 249.51 inches²

The cafeteria ordered 400 paper plates. They used 226 at breakfast. They bought 100 more. Then, they used some plates for lunch. Now there are 78 plates. How many plates did they use at lunch?
If the cafeteria ordered 400 paper plates. They used 226 at breakfast. They bought 100 more. Then, they used some plates for lunch. Now there are 78 plates. The number of plates that was used at lunch is 196.
Number of plated usedGiven :
Paper plates ordered = 400 plates
Plates used for breakfast = 226
Additional plate bought = 100
Plate used for lunch = ?
Hence,
Let calculate the plate left after breakfast
Number of plates = Paper plates ordered - Plates used for breakfast
Number of plates = 400 plates - 226 plates
Number of plates = 174 plates
Now let determine the plates that were used for lunch
Pates used for lunch :
Pates used for lunch = (174 + 100) -78
Pates used for lunch = 274 -78
Pates used for lunch = 196 plates

3. A bus travels a distance of 60 km at a steady speed of 60 km/h. (a) Does the distance travelled vary directly with time?If the journey takes 8 hours, find its speed.
a) The distance that the bus traveled varies directly with time.
b) If the journey of 60 km takes 8 hours, the speed of the bus is 7.5 km/h.
What is the relationship between distance and speed?The relationship between distance and speed can best be explained below:
For a constant speed, for example, 60 km/h, the distance traveled, 60 km, is proportional to the time used.
But if the distance is fixed at 60 km, the time it takes the bus, for example, 8 hours, is inversely proportional to the speed.
Total distance = 60 km
Steady speed = 60 km/h
Thus, for every kilometer, the bus takes one minute (60/60) and for every minute, the bus travels a kilometer.

Select the counterexample that shows that the conjecture is false.
Conjecture: The product of two positive numbers is always greater than either number
Answer: 1*5=5 is the counterexample.
Step-by-step explanation: The conjecture stated is that the product of two positive numbers is always greater than either number. We have to find certain values to check and see if this conjecture is false. We can use the numbers 1 and 5 to multiply. This would be the identity property of multiplication. 1 and 5 are both positive numbers and therefore that 1*5=5 is the counterexample.
In the lab, Charlie has twosolutions that contain alcohol and is mixing them with each other. Solution A is 20% alcohol and Solution B is 6%
alcohol. He uses 300 milliliters of Solution A. How many milliliters of Solution B does he use, if the resulting mixture is a 12% alcohol solution?
Charlie used 400 milliliters of Solution B if the resulting mixture is a 12% alcohol solution.
What does "algebraic equation" mean?An algebraic equation is a declaration of the equality of two expressions created by applying the algebraic operations to a set of variables.
What kind of algebraic equations are there?Monomial expressions, binomial expressions, and polynomial expressions are the three main categories of algebraic expressions.
Given : Solution A contains 20% alcohol, while Solution B contains 6% alcohol.
It is also given that Charlie uses 300 milliliters of Solution A.
Let's say that the mixture contained x ml of the 6% solution B.
x + 300 = resulting mixture of 12 % alcohol.
20% (300) + 6% (x) = 12% (x+300)
60 + 0.06x = 0.12x + 36
0.06x = 24
x = 400 milliliters
As a result, if the resulting mixture is a 12% alcohol solution, he used 400 milliliters of Solution B.

Which description best compares the graph given by the following equations:
Based on the equations given, the best comparison between them is that they are intersecting but not perpendicular.
How to know lines that are perpendicular?When lines are perpendicular to each other, one line will have a slope that is the negative reciprocal of the other. For instance, if the slope of one line is 2, the slope of the perpendicular line will be -1/2.
Parallel lines will have the exact same slope.
The slope of the first line is:
2x - 7y = -5
(2x - 7y = -5) x 1/7
2/7x - y = -5/7
Slope = 2/7
The slope of the second line is:
x - 3y = 4
(x - 3y = 4) x 1/3
1/3x - y = 4/3
Slope = 1/3
The slopes are neither negative reciprocals nor the same so the lines must be intersecting but not perpendicular.
