Answer:
8 = m, No solution
Step-by-step explanation:
1. -88 = -3(4m + 5) - (1 - 3m)
-88 = -12m - 15 - 1 + 3m : distributed into parentheses
-88 = -9m - 16 : combined like terms
+16 + 16 : adding to cancel out
-72 = -9m
/-9 /-9 : dividing by -9 to cancel
8 = m
2. -4(5k - 7) + 2k = -2(9k + 5)
-20k + 28 + 2k = -18k - 10 : distributed into parentheses
-18k + 28 = -18k - 10 : combined like terms
+ 10 + 10 : adding to cancel out
-18k + 38 = -18k
+18k +18k : adding to cancel out
38 = 0k (No solution)
Solve -4(1.75 + x) = 18
Answer:
-25/4
Step-by-step explanation:
-4 ( 1.75 + x ) = 18
-7 - 4x = 18
-4x = 18 + 7
-4x = 25
x = 25 ÷ -4
x = - 25/4

=================================================
Explanation:
mu = population mean = 1300
sigma = population standard deviation = 20
Compute the z score based on x = 1330
z = (x-mu)/sigma
z = (1330-1300)/20
z = 30/20
z = 1.5
Asking to compute P(X < 1330) is the same as P(Z < 1.5) in this specific context when mu = 1300 and sigma = 20.
Use a Z table or a calculator to find that P(Z < 1.5) is roughly 0.93319
About 93.319% of the 755 bulbs are expected to last less than 1330 hours.
0.93319*755 = 704.55845
That value rounds to 705

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.

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.

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].

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

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.
