Answer:
Step-by-step explanation:
At Home Depot, Johnny bought 3 rose bushes and 7 flats of petunias for a total of $114.75.
Let x = rose bushes
Let y = petunias
This means;
3x + 7y = 114.75 ..... (i)
Rosie bought 2 rose bushes and 6 flats of petunias for a total of $89.50.
2x + 6y = 89.50 ..... (ii)
How much does a rose bush cost? How much does a flat of petunias cost?
Multiply eqn (i) by 2 and eqn (ii) by 3.
This results too;
6x + 14y = 229.5 .... (iii)
6x + 18y = 268.5 .....(iv)
Subtract eqn (iii) from eqn (iv)
This results to;
4y = 39
y = 39 / 4 = $9.75
Subt the vale of y in eqn ii
2x = 89.50 - 6y
x = (89.50 - 6y) / 2
x = (89.50 - 6(39 / 4)) / 2
x = 31 / 2 = $15.5
Solve and explain. Sue orders pictures from her photographer. Each picture costs $8. A one-time shipping fee of $7 is added to the cost of every order. The total cost of Sue’s order is $31. How many pictures did Sue order?
Answer:
3 pictures
Step-by-step explanation:
Please see the attached pictures for the full solution.
☆ Since the shipping fee is a one-time fee, for an order, Sue only pays $7 once and the rest of the cost would be due to the number of pictures she ordered.

Trapezoid A B C D is shown. An altitude with length 5 is drawn from point B to side A D. The length of B C is 14, the length of C D is 6, and the length of base A D is 16. Use the formula A = One-halfh(b1 + b2). What is the area of the trapezoid? 32, 60, 75, 560, square units
Answer:
C. 75 square unitsStep-by-step explanation:
From the question we see that:
b1 = AD = 16 , b2 = BC = 14 , h = 5Use the formula for the area:
A = 1/2(b1 + b2)hA = 1/2(16 +14)(5) = 1/2(30)(5) = 75Correct choice is
C. 75 square unitsAnswer:
75 is correct on edge

Write the equation of the line that passes through the points (4,8) and (1, -8). Put
Answer:
3y - 16x = -40
Step-by-step explanation:
Given the coordinate points (4,8) and (1, -8).
The point slope form of the equaton is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
Get the slope
m = -8-8/1-4
m = -16/-3
m = 16/3
Get the required equation using the point (1, -8)
y - (-8) = 16/3 (x-1)
y+8 = 16/3 (x-1)
3(y+8) = 16(x-1)
3y + 24 = 16x - 16
3y - 16x = -16 - 24
3y - 16x = -40
Hence the required equation is 3y - 16x = -40

A golf instructor is interested in determining if her new technique for improving players’ golf scores is effective. She takes four (4) new students. She records their 18-hole scores before learning the technique and then after having taken her class. She conducts a hypothesis test. Player 1 Player 2 Player 3 Player 4 Mean score before class 83 78 93 87 Mean score after class 80 80 86 86 This is which of the following and Why? 1. a test of two independent means. 2. a test of two proportions. 3. a test of a single mean. 4. a test of a single proportion.
Answer:
A test of two independent means.
Step-by-step explanation:
The test above is comparing the two independent mean scores (mean before taking her class ; μ1 and mean score after taking her class, μ2. This two mean values are tested to ascertain if there exist any statistical difference between them. This differs from the proportion which is ecekuared by the ratio of success or failure. The single mean and single proportion test only has one group which its mean or proportion is tested.
The null and alternative hypothesis for two independent sample means may be expressed thus :
H0 : μ1 = μ2
Alternative hypothesis
H1 : μ1 ≠ μ2

Write the linear inequality shown in the graph. The gray area represents the shaded region. y ≤ –x + 4 y ≤ –x – 4 y ≥ –x – 4 y ≥ –x + 4
For Example:
Write the linear inequality shown in the graph. The gray area represents the shaded region.
A. y ≤ 3x + 4
B. y ≤ 3x – 4
C. y ≥ 3x + 4
D. y ≥ 3x – 4
Answer: C
Step-by-step explanation:
1. The graph indicates that the line intersect the y-axis at -4.
2. Then, you must choose any point that are located within the region and replace them to see if the inequality is satisfied. Therefore, you have:
Point (0,2)

Point S is between points R and T. Given that
RS ST and RS = 16, what is RT?
Answer:
32
Step-by-step explanation:
Reason: point S is between points are and t
Meaning that Line RS≅ST
So if RS=16 then ST=16
To find RT we just add ST and RS
16+16=32
Therefore RT=32

All employees have a salary of about $40,000
$64,000
Between 40,000 to 64,000
Half of the employees earn higher than $40,000
Answer:
The last one, Half of the employees earn higher than $40,000
Step-by-step explanation:
The MEDIAN, or Middle salary is $40,000. That is the numbed that is right between all of the salaries. So since it is in the middle, then half of the people are above it, therefore it is the last one.

Answer:
15 because when you add 30 and 45 together, you get 75. There is 90 degrees in that angle, so to get 90 degrees, you need to have 15 more degrees
Answer:
The measure of DAC is 15 degrees.
Step-by-step explanation:
Since there are three angles that make up this 90 degree angle. we need to find the missing angle from the other two. To do this, subtract the known angles from 90 degrees.
[tex]90 - 35 - 40 = 15[/tex]
The measure of the missing angle is 15 degrees.
ALGEBRA METHOD:
You can also use a variable to find the missing measurement.
[tex]45 + 30 + x = 90 \\ 75 + x = 90 \\ x = 15[/tex]
The measure of the angle, x, is equal to 15 degrees.
