What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
Gloria likes to knit scarves to give as gifts to her friends and family.
She can knit 1 over 4 of a scarf in 3 over 4 of an hour.
Simplifying,
She can knit 1/4 of a scarf in 3/4 of an hour.
To find the time:
1/4 of a scarf in 3/4 of an hour.
Multiply by 4,
4 x 1/4 of a scarf in 4 x 3/4 of an hour.
1 scarf in 3 hours.
Therefore, she will take 3 hours to knit 1 scarf.

Given that p²,q² are two roots of x²-x+16=0.
Form another equation with roots 1/p,1/q.
Answer:
x² -3/4x +1/4 = 0
Step-by-step explanation:
Consider the two equations in factored and expanded forms:
(x -p²)(x -q²) = x² -(p²+q²)x +p²q² = 0 ⇒ p²+q² = 1, p²q² = 16
and
(x -1/p)(x -1/q) = x² -(1/p+1/q)x +1/(pq) = 0
Consider the squares of the sum and product of roots:
constant term: (1/(pq))² = 1/(p²q²) = 1/16 ⇒ 1/(pq) = √(1/16) = 1/4
x-term: (1/p +1/q)² = (p +q)²/(pq)² = (p² +q² +2pq)/(p²q²)
= (p² +q²)/(p²q²) +2/(pq)
= 1/16 +2/√16 = 9/16 ⇒ (1/p +1/q) = √(9/16) = 3/4
Then the equation with roots 1/p and 1/q is ...
x² -3/4x +1/4 = 0

Pls help me with this question
Step-by-step explanation:
A
the answers are already right in picture. we only need to count.
maybe the problem is understanding a cube ? when it says here "the edge of each cube is 1 1/2 in long", then it means that every side length of a cube is the same (length, width, height). it is the principle of a 2-dimensional square in 3 dimensions.
and "prism" is simply another word for "box".
so, we see that there are 5 cubes fitting along the length of the prism.
so, the length of the prism is
5× 1 1/2 in = 5× 3/2 = 15/2 = 7 1/2 in.
3 cubes are the width of the prism.
so, the width of the prism is
3× 1 1/2 in = 3× 3/2 = 9/2 = 4 1/2 in.
B
we know the height of the prism is 3/4 ft.
1 ft = 12 in
3/4 ft = 3/4 × 12 = (3×12)/4 = 36/4 = 9 in
how many layers of cubes fit into 9 in ?
well, that is what we use division for :
9 ÷ 1 1/2
this is the same as
9 / 3/2 = (9/1) / (3/2)
to divide by a fraction is the same as to multiply with the upside-down fraction. therefore :
(9/1) × (2/3) = (9×2) / (1×3) = 18/3 = 6
so, 6 layers of the cubes fit into the prism.
An account earns 8.4% interest compounded monthly. If 12,000 is invested in the account initially, how much
interest is earned in this account over a 25 year period?
Answer:
$30,2400
Step-by-step explanation:
First, we need to find how much interest he earns in a month
8.4% of $12,000 = $1,008
Next, we multiply the amount of interest per month by the number of months in 25 years
25 years = 300 months
Now we can multiply the two values to get our final answer
1,008 x 300 = $30,2400

Answer:(-8,6) (-5,8
Step-by-step explanation:
for each fraction below find an equivalent fraction with a denominator 200.
fraction 14/25
Answer:
112/200
Step-by-step explanation:
To find an equivalent fraction with a new denominator you can simply multiply by 1. However, you must multiply by different forms of 1. Remember that any number divided by itself is equal to 1. Additionally, because of the identity property of multiplication, any number multiplied by 1 is still equivalent.
In this case, you should multiply by a fraction that will make 25=200. To get 200 from 25 you must multiply by 8. So, multiply the whole fraction by 8/8. This gives you (14/25)*(8/8)=112/200.

the volume is 8 cm^3
8 x 12 x 10 = 960 cm^3
8 / 2 = 4
12 / 2 = 6
10 / 2 = 5
4 x 6 x 5 = 120
you can fit up to 120 cubes into the container

The Triangle Proportionality Theorem Converse states that if a line splits two sides of a triangle proportionally, the line is parallel to the remaining line.
Here, we can see that the sides are split into congruent lengths to each other, making their proportions 1:1. This proves the theorem converse, so 5x is parallel to 8x+10. Because the other two sides are connected to each other, with AB being a part of AC and AE being a part of AD, AB is parallel to AC and AE is parallel to AD. Given this, we can say that triangle ABE is similar to triangle ACD.
In a similar triangle, the lines corresponding to each other have the same ratio as other lines. This means that
AB/AC = AE/ED = BE/CD.
We are trying to find BE and CD to solve for x, and we can do this by finding the ratio between them
AC = AB + BC
BC = AB
AC = 2 * AB
AB / (2*AB) = BE / CD
1/2 = 5x/(8x+10)
multiply both sides by 2 to remove a denominator
1 = 10x / (8x+10)
multiply both sides by 8x+10 to remove the other denominator
8x+10 = 10x
subtract 8x from both sides to put the variable and its coefficients on one side
2x = 10
divide both sides by 2 to solve for x
x = 5
What is the slope-intercept equation of the line containing the points (–5, 22) and (4, 49) ?

Jamar drove 228 miles and used 6 gallons of gas.
a) How many miles/gallon did he get on the trip?
b) On another trip, he used 9 gallons of gas. How far did he travel?
Step-by-step explanation:
a)
well, it is kind of written already :
228 miles and 6 gallons.
so, miles/gallon = 228/6 = 38 miles/gallon.
b)
it is not mentioned, but I guess we have to assume that he got the same miles/gallon ratio on this trip as well.
so, again
38 miles/gallon
and he used 9 gallons.
so, he drove 38×9 = 342 miles
