Answer:
1. (rose bunches, lily bunches) ∈ {(2, 3), (4, 6), (6, 9), (8, 12)}. The least is (2, 3).
2. 6(2+3); 14(3+1); 9(4+3)
Step-by-step explanation:
I like Euclid's algorithm for finding the greatest common factor (GCF): divide the larger number by the smaller, and note the remainder. If the remainder is zero, the smaller is the GCF; if not, use the remainder in place of the larger number and repeat.
__
1. The GCF of 8 and 12 is 4, so the least common multiple is ...
LCM(a, b) = ab/GCF(a, b)
LCM(8, 12) = 8·12/4 = 24
24 roses is 2 bunches; 24 lilies is 3 bunches. Up to 8 bunches of roses can be ordered to keep the number less than 100.
The florist could have ordered these numbers of bunches (roses, lilies):
(2, 3), (4, 6), (6, 9), (8, 12)
The least order is 2 bunches of roses and 3 bunches of lilies.
__
2.
A. GCF = 6, so the factored form is 6(2+3)
B. GCF = 14, so the factored form is 14(3+1)
C. GCF = 9, so the factored form is 9(4+3)
Evaluate the expression below when x = 24 and y = 6.

Solve 3(4b – 2) = -6 + 12b
Answer:
All real numbers make his equation true.
Step-by-step explanation:
A shopkeeper purchased 100 blankets at Rs. 2000 each. He found that 10 blankets were
defective and he sold these at Rs. 1200 each. At what rate should he sell the remaining
blankets so as to gain 14% on the whole ?
Answer:
2,400.
Step-by-step explanation:
Since the shopkeeper bought 100 blankets at $ 2000 each, he spent a total of $ 200,000. He wants to make a total profit of 14% through his sale, that is, he wants to make sales for $ 228,000 (200,000 x 1.14).
Since he sold 10 defective blankets at $ 1200 each, he recovered a total of $ 12,000. Therefore, he has $ 216,000 (228,000 - 12,000) left to achieve his goal, through the sale of 90 blankets. Therefore, you must sell each blanket for $ 2,400 (216,000 / 90) to make the desired profit.

This table models a linear function.
x -8 -4 4 8
y -1 0 2 3
Enter the coordinates of the y-intercept in the boxes.
Answer:
[tex](x,y) = (0,1)[/tex]
Step-by-step explanation:
Given
The above table
Required
Determine the coordinates of the y intercept
Represent points on the table as:
[tex](x_1,y_1) = (4,2)[/tex]
[tex](x_2,y_2) = (8,3)[/tex]
First, calculate slope (m):
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{3-2}{8 - 4}[/tex]
[tex]m = \frac{1}{4}[/tex]
For y intercept, the following coordinate point exist:
[tex](x_3,y_3) = (0,y)[/tex]
Because x = 0 at y intercept
Calculate the slope as:
[tex]m = \frac{y_3 - y_1}{x_3 - x_1}[/tex]
The equation becomes
[tex]\frac{1}{4} = \frac{y - 2}{0 - 4}[/tex]
[tex]\frac{1}{4} = \frac{y - 2}{- 4}[/tex]
Cross Multiply:
[tex]4(y-2) = -4 * 1[/tex]
Divide through by 4
[tex]y - 2 = -1 * 1[/tex]
[tex]y - 2 = -1[/tex]
Make y the subject:
[tex]y = 2-1[/tex]
[tex]y = 1[/tex]
Hence, the coordinates of the y intercept is:
[tex](x,y) = (0,1)[/tex]

classroom was 12 feet and the width was 8 feet. How much carpet would she need
to buy?
Answer:
96 ft^2
Step-by-step explanation:
12ft × 8ft to find area of classroom
96ft so Ms. Ledford has to buy 96 square feet of carpet
Answer:
96 ft^2
Step-by-step explanation:

Write a list of steps that are needed to find the measure of ZB.
Step-by-step explanation:
the exterior angle is equal to the sum of the interior angles on the opposite side.
As in angle BCD = angle BAC + angle ABC
113 = 72+angle ABC
angle ABC = 41
Answer:
180-113 to find the linear angle.
add that result with 72.
once found the sum, use 180 to subtract the sum to get angle B.

Step-by-step explanation:
The fastest time for completing an obstacle course is 218 seconds. Artest completed the first half of the course in 95 seconds. It took him 124 seconds to finish the second half. a. What is Artest's total time? b. How does his time compare to the fastest time?
Answer:
219 Seconds ; He was 1 second faster
Step-by-step explanation:
Two halfs equal one whole, meaning both of the times added will equal the full time he took:
95+124=219
219 Seconds
He was 1 second faster because:
219-218=1
What is the midpoint of the segment shown below?
Answer:
We conclude that the midpoint of the segment is:
[tex]\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]Hence, option D is correct.
Step-by-step explanation:
Given the points
(-6, -1)(-3, 4)Finding the midpoint of the segment using the formula
[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(-6,\:-1\right)[/tex]
so
[tex]=\left(\frac{-6-3}{2},\:\frac{-1+4}{2}\right)[/tex]
[tex]=\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]
Therefore, we conclude that the midpoint of the segment is:
[tex]\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]Hence, option D is correct.

determine the value of p if one root of equation x^2+px+1=0 is the square of other.
Answer:
-2
Step-by-step explanation:
Given equation is x²+px+1=0
comparing the equation with ax²+bx+c=0
then a=1,b=p,c=1
let the roots one root of the equation be A then
by question, another root is A².
we know
A(ALPHA)+A²(beta)=-b/a
A+A²=-p/1
A+A²=-p......1
again
A*A²=c/a
A³=1/1
A³=1
A=1
Now,
substituting A=1 in equation 1
1+1²=-p
2=-p
Therefore p=-2.

Contestants in the Run-and-Bike-a-thon
run for a specified length of time, then bike for a specified length of time. Jason ran at an average speed of 5.2 mi/h
and biked at an average speed of 20.8 mi/h,
going a total of 14.4 miles. Seth ran at an average speed of 10.4 mi/h and biked at an average speed of 18.2 mi/h,
going a total of 18 miles. For how long do contestants run and for how long do they bike? Round to the nearest hundredth if necessary.
Contestants run__hour and bike___hour.
Answer:
They ran for 0.923 hrs and biked for 0.46 hrs
Step-by-step explanation:
First thing to do is write down the inequality of the question
5.2x + 20.8y = 14.4
10.4x + 18.2y = 18
Multiplying the whole equation by 10, so as to eliminate the decimal places, we have.
52x + 208y = 144
104x + 182y = 180
Multiplying the first equation by 2, we have
104x + 416y = 288, next we solve it simultaneously with the second equation
104x + 416y = 288
104x + 182y = 180
Subtract 2 from 1, and we have..
416y - 182y = 288 - 180
234y = 108
y = 0.46
Now, we go back and substitute for y in the earlier equation, so that
52x + 208(0.46) = 144
52x + 95.68 = 144
52x = 144 - 95.68
52x = 48.32
x = 48.32/52
x = 0.929
the height of a shed is 6cm. a ladder leans agaisnt the shed with its base 4.5 m away, and its top just reaching the roof. what is the length of the ladder?
Answer:
4.5m
Step-by-step explanation:
The set up is a right angles triangle
Height of the shed = opposite side = 6cm
Distance of the ladder from the shed = adjacent = 4.5m
Lenght of the ladder = Hypotenuse = x
Using pythegoras theorem to find the length of the ladder
hyp² = opp²+adj²
hyp² = 0.06² + 4.5²
hyp²= 0.0036+20.25
hyp² = 20.2536
hyp = √20.2536
hyp = 4.50m
Hence the length of the ladder is 4.5m
