A small container of detergent holds 75% as much as the large container of detergent. If the small container hold 36 ounces, the large container will hold ounces.
Answer:
48 ounces
Step-by-step explanation:
Let the amount in small container be x and that of largest be y
If a small container of detergent holds 75% as much as the large container of detergent, this can be represented as;
x = 75% of y
Given x = 36
36 = 75% of y
36 = 0.75y
y = 36/0.75
y = 48 ounces
Hence the large container will hold 48 ounces

Answer:
9x² + 16y² - 24xy
Step-by-step explanation:
(3x - 4y)²
⇒ (3x)² + (4y)² - 2 (3x) (4y) {(a - b)² = a² + b² - 2ab}
⇒ 3²x² + 4²y² - 2 (12xy)
⇒ 9x² + 16y² - 24xy

A parallelogram has sides 8 ft and 14 ft the height corresponding to the 14 ft base is 4 ft what is the height corresponding to the 8 ft base
Given :
A parallelogram has sides 8 ft and 14 ft the height corresponding to the 14 ft base is 4 ft.
To Find :
The height corresponding to the 8 ft base.
Solution :
Since, both parallelogram are similar. So, ratio of the sides of parallelogram is similar in both the cases.
[tex]\dfrac{h_1}{h_2}=\dfrac{b_1}{b_2}\\\\\dfrac{8}{14}=\dfrac{h_1}{4}\\\\h_1 = \dfrac{8\times 4}{14}\\\\h_1 = 2.285 \ ft[/tex]
Therefore, the height corresponding to the 8 ft base parallelogram is 2.285 ft.

Find the probability of drawing two diamonds in a row from a standard deck of 52 cards. After the first card is drawn it is set aside and not returned to the deck.
Answer: 1/17
Step-by-step explanation:
First and foremost, we should note that there are 13 diamonds in a standard deck of 52 cards.
If the first card is drawn, the probability of picking a diamond is 13/52. Since it's not replaced, when another one is picked, the probability that it will be diamond will be 12/51.
We then multiply both together. This will be:
= 13/52 × 12/51
= 1/4 × 4/17
= 1/17

Answer:
A=2.5
B=2
Step-by-step explanation:
A parallelogram has to have the opposite sides equal each other. In this case side LM and side ON have to be equal.
We can compare the two sides using algebra.
4b+7=8b-1
Using simple methods, we can isolate b on a single side.
1+7=8b-4b
8=4b
b=2
From this we learn b is 2. To find out the value of A on side MN and LO, we will plug in the value for b at all instances of B in this equation.
2a = 2b+1
2a = 2(2)+1
2a=4+1
2a=5
a=2.5

Khalid and Jesse took different overnight trains.
The graph shows the relationship between the total distance Khalid traveled and the time in hours.
The distance Jesse traveled after x hours is given by the equation y = 150x. Who, if anyone, traveled at a faster speed?
Use the drop-down menus to explain your answer.
Khalid’s rate is ____ miles per hour. Jesse’s rate is ____ miles per hour. So, ____ train traveled at a faster speed.
Answer:
Khalid’s rate is ___140_ miles per hour. Jesse’s rate is _150___ miles per hour. So, _Jesse’s___ train traveled at a faster speed.
Step-by-step explanation:
The general equation of a straight line is
y = mx + b
for y = 150x
We have the slope as 150
This is 150 miles/hour
This relates to Jesse’s train speed
for Khalid, we have his own speed obtainable from the graph
The speed is simply the slope of the graph
We proceed to select two points from the graph and find the slope
The points are; ((1,140) and (4,560)
Mathematically, the slope will be;
m = (y2-y1)/(x2-x1)
m = (560-140)/(4-1) = 420/3 = 140 miles per hour
Mr. Miller has a 20-foot ladder, which he
wants to reach 18 feet up the side of his
house. To the nearest foot, how far from the
base of the house should he place the
ladder?
Answer:
8 ft
Step-by-step explanation:
the ladder will make a right angle triangle with the house. The hypotenuse of the triangle is the ladder, 20 ft, and the height of the triagnle is 18 ft.
Solve for the base of the right angle triangle using pythagorean's theorem:
c=20, a=18, b=?
[tex]b^{2}=c^{2} - a^{2}\\b^{2}=20^{2} - 18^{2}[/tex]
[tex]b=\sqrt{72}[/tex]
[tex]b= 8.49 ft[/tex]
round to the nearest foot,
b = 8 ft
