In one day, The Tool Shed rented out 25 self-propelled and riding mowers for a total fee of $900. The dolly rental cost was $20 for each self-propelled mower and $40 for each riding mower. Find the number of self-propelled mowers "(x)" and the number of riding mowers " (y)' rented for that day
They rented out 5 self-propelled mowers and 20 riding mowers.
Data;
Total number of tool rented out = 25Cost of tools rented = $900System of EquationsTo solve this problem, we have to write a system of equations to represent the problem.
since we have
x = self - propelled mowery = riding mowersLet's write equations with these variables.
[tex]x+y = 25...equation (i)\\20x+40y = 900...equation(ii)[/tex]
From equation (i)
[tex]x+y= 25\\x = 25 - y...equation(iii)[/tex]
Put equation (iii) into equation (ii)
[tex]20x+40y=900\\x = 25-y\\20(25-y)+40y=900\\\\500-20y+40y=900\\500+20y=900\\20y=900-500\\20y=400\\\frac{20y}{20}=\frac{400}{20}\\ y=20[/tex]
Let's substitute the value of y into equation(i)
[tex]x+y =25\\x+20 = 25\\x = 25 - 20\\x = 5[/tex]
From the calculations above, they rented 5 self-propelled mowers and 20 riding mowers.

Write the equation in slope-intercept form that has a x-intercept of 30 and a y-intercept of 15
Answer:
[tex]\displaystyle y = -\frac{1}{2}\, x + 15[/tex].
Step-by-step explanation:
All non-horizontal line in the cartesian plane intersects the [tex]x[/tex]-axis at a unique point. The [tex]x\![/tex]-coordinate of that point is the [tex]\! x[/tex]-intercept of this line.
The [tex]x[/tex]-intercept of the line in this question is [tex]30[/tex]. Thus, the [tex]x\![/tex]-coordinate of the intersection of this line and the [tex]\! x[/tex]-axis would be [tex]30\![/tex].
Like all other points on the [tex]x[/tex]-axis, the [tex]y\![/tex]-coordinate of that intersection would be [tex]0[/tex]. Therefore, the coordinates of that intersection would be [tex](30,\, 0)[/tex].
Similarly, the [tex]y[/tex]-intercept of a non-vertical line is the [tex]y\![/tex]-coordinate of the point where that line intersects the [tex]y\!\![/tex]-axis.
The slope-intercept form of a line is in the form [tex]y = m\, x + b[/tex], where [tex]m[/tex] is the slope of the line and [tex]b[/tex] is the [tex]y[/tex]-intercept of this line. Both [tex]m\![/tex] and [tex]b\![/tex] are constants.
It is given that the [tex]y[/tex]-intercept of the line in this question is [tex]15[/tex]. Therefore, [tex]b = 15[/tex]. The slope-intercept equation of this line would be [tex]y = m\, x + 15[/tex] for some slope [tex]m[/tex] to be found.
All points [tex](x,\, y)[/tex] on this line should satisfy the equation [tex]y = m\, x + 15[/tex] of this line. The [tex]x[/tex]-intercept of this line, [tex](30,\, 0)[/tex], is a point on this line. Thus, the equation [tex]y = m\, x + 15\![/tex] should hold for [tex]x = 30[/tex] and [tex]y = 0[/tex]. Substitute these two values into the equation and solve for the slope [tex]m[/tex]:
[tex]0 = 30\, m + 15[/tex].
[tex]\displaystyle m = -\frac{1}{2}[/tex].
Therefore, the slope-intercept equation of this line would be:
[tex]\displaystyle y = -\frac{1}{2}\, x + 15[/tex].
Calculate the value of x and give reason.
since these two angles are the same, we can write down following equation:
70=x+20
then x = 50
Find the value of x.
If necessary, you may learn what the markings on a figure indicate.
Answer:
x = 36
Step-by-step explanation:
The two markings mean the sides are congruent. The triangle with two congruent sides is an isosceles triangle. According to base angle theorem (only applicable to isosceles triangles), the two base angles are equal.
The angle adjacent to x is 27.
The sum of all angles in a triangle is 180
We can create an equation using parts whole postulate (PWP.)
x + 27 + 27 + 90 = 180
x + 54 + 90 = 180
x + 144 = 180
x = 36

An engineer stands 30 ft. from a building and notes a 55 degree angle of elevation to the top of the building. How high is the building? Round your answer to 1 decimal place.
Work Shown:
h = height of the building
h is opposite the reference angle (55)
the adjacent side is 30 feet
tan(angle) = opposite/adjacent
tan(55) = h/30
h = 30*tan(55)
h = 42.84444 which is approximate
h = 42.8 feet

Find the area of the figure.
5.2 ft
6.5 ft
3.9 ft
10.4 ft
The area is
square feet.
Answer:
77.74 square feet
Step-by-step explanation:
1. We have to keep the triangle and the rectangle apart and find the area of each separately then add the areas together.
The formula for the area of a rectangle is height x width = area
So, 6.5 feet x 10.4 feet = 67.6 feet squared
The formula for the area of a triangle is height x width x (1/2) = area
So, 5.2 feet x 3.9 feet x (1/2) = 10.14 feet squared
Now, add the two areas together.
10.14 square feet + 67.6 square feet = 77.74 square feet
Answer: 77.74 square ft
Step-by-step explanation:
first do the rectangle. 10.4 times 6.5. then traiangle(b times height divided by 2). then add them together.

Aroon is asked to choose five integers so that the mode is 2 more than the median and the mean is 2 less than the median.
What is the largest possible value of the range of Aroon's five integers?
The relation between Mean, Median and mode is given by
Mode= 3 Median - 2Mean---- equation1
According to the given condition
Mode= 2+median ----- equation 2
Putting equation 2 in equation 1
2+median= 3 Median - 2Mean
2 Mean= 3 Median - 2- Median
2 Mean= 2 Median - 2
Mean= Median-1
Mean- Median=1--------Eq. A
According to the second condition
Median- Mode=-2-----------eq. 3
Putting eq. A in eq. 3
Mean -1 - Mode=-2
Mean- Mode=-1
or
Mode- Mean=1------equation 4
Adding equation A and equation4
Mode- Mean=1
Mean- Median=1
Mode+ Median =2------- equation5
Again Putting equation2 in equation 5
2+median + Median =2
2 Median =2-2
2 Median =0
Median=0
Mean= 0-1
Mean= 0-1=-1
Mode- Mean=1
Mode-(-1)=1
Mode=0
Putting values in the formula of mean
x bar =∑x/5
(-1)5 = 0+0+ x1+x2+0
-5= x1+x2
So the highest value is 0.

So, your task this week is a maths problem;
The distance between Exeter and London is 175 miles. Sam left Exeter at 10:00 on Tuesday for London. Morgan left London for Exeter at 13:00 the same day. They travelled on the same road. Up to the time when they met, Sam's average speed was 25 miles per hour, and Morgan's average speed was 35 miles an hour.
At what time did Sam and Morgan meet?
Answer: Sam and Morgan met up at 18:00. Sam left Exeter at 10:00, and was on the road for 7 hours. I know this because 175 / 25 = 7. 10:00 + 7:00 = 17:00 meaning Sam got there at 17:00. Morgan on the other hand left at 13:00 and had an average speed of 35 mph. 175/35=5. 13:00 + 5:00 = 18:00. By 18:00 both Sam and Morgan had arrived in London thus 18:00 us your answer.

4. Find the actual area of the kitchen.
(REMEMBER: Final label is ft.)
Hallway = (1/2 in. (width) x (2 in. (length) + 3 in. (length)) x 6 ft. (actual size)
Hallway = (1/2 in. (width) x 5 in. (length)) x 6 ft. (actual size)
Hallway = 5/2 in. (area) x 6 ft. (actual size)
Hallway = 15 ft^2 (final answer)
Kitchen = (3 in. (width) x 3 in. (length)) x 6 ft. (actual size)

35$
Step-by-step explanation:
25 x 1.40 = 35
Can someone explain this? Plzzzz
The value is approximate. Round it however you need to.
====================================================
Explanation:
x = number of years
y = cost
The teacher wants to know what value of x will make y = 2500.
Plug it in and solve for x.
y = 134.02x + 655.40
2500 = 134.02x + 655.40
2500-655.40 = 134.02x
1844.6 = 134.02x
x = 1844.6/134.02
x = 13.7636 approximately
Somewhere between year 13 and 14 is when the price should be $2500. This is of course based on the regression line estimate which isn't perfect.
