Answer: 56
Step-by-step explanation:
Given that :
Marbles in bag are only red and blue ;
Probability of randomly choosing a red = 2/7
Number of red marbles in bag = 16
The total Number of marbles =?
P(choosing a red marble) = required outcome / Total possible outcomes
Required outcome = number of red marbles
Total possible outcomes = total number of blue and red marbles
Total number of blue and red marbles = x
P(choosing a red marble) = required outcome / Total possible outcomes
2/7 = 16 / x
Cross multiply
2x = 16 * 7
2x = 112
x = 112 / 2
x = 56 marbles
Total number of marbles = 56

Answer:
(C). (t² - p)( [tex]t^{4}[/tex] + pt² + p²)
Step-by-step explanation:
a³ - b³ = (a - b)(a² + ab + b²)

we conclude that:
[tex]\frac{2p}{4p^2-1}\div \frac{6p^3}{6p+3}=\frac{1}{2p^3-p^2}[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{2p}{4p^2-1}\div \frac{6p^3}{6p+3}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]
[tex]=\frac{2p}{4p^2-1}\times \frac{6p+3}{6p^3}[/tex]
[tex]=\frac{2p}{4p^2-1}\times \frac{2p+1}{2p^3}[/tex]
[tex]\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]
[tex]=\frac{2p\left(2p+1\right)}{\left(4p^2-1\right)\times \:2p^3}[/tex]
cancel the common factor: 2
[tex]=\frac{p\left(2p+1\right)}{\left(4p^2-1\right)p^3}[/tex]
cancel the common factor: p
[tex]=\frac{2p+1}{p^2\left(4p^2-1\right)}[/tex]
[tex]=\frac{2p+1}{p^2\left(2p+1\right)\left(2p-1\right)}[/tex]
cancel the common factor: 2p+1
[tex]=\frac{1}{p^2\left(2p-1\right)}[/tex]
Expanding
[tex]=\frac{1}{2p^3-p^2}[/tex]
Thus, we conclude that:
[tex]\frac{2p}{4p^2-1}\div \frac{6p^3}{6p+3}=\frac{1}{2p^3-p^2}[/tex]
A math test has 12 multiplication problems and 24 division problems.
What is the ratio value of multiplication problems to division problems?
Type your answer as a fraction in simplest form.
Answer:
12:24 = 1:2
Step-by-step explanation:
Since there are 12 multiplication problems, and 24 division problems, the ratio of multiplication and division problems are 12:24, now we need to put it in simplest form.
We need to find the highest number of which both are divisible by, 12 and 24 are both divisible by 12.
So 12÷12 = 1, and 24÷12 = 2, so 12:24 in simplest form is 1/2 or 1:2.
Answer:
1/2
Step-by-step explanation:
12 is half of 24. Therefore, the answer as a fraction in simplest form is 1/2.

Answer:
x=6
MKL=37
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. because U is between T and B
TU +UB = TB
2x+3x+1 =21
5x = 20
x= 4
mTU = 2x = 2*4 = 8
mUB = 3x+1 = 3*4 +1 = 12 +1 = 13
2.
m∠JKL = 59°
m∠MKL + m∠JKM = m∠JKL
5x+7 +2x+10 = 59
7x +17 = 59
7x = 59-17
x = 42/7 = 6
m∠MKL=5x+7 = 5*6 +7 = 30+7 = 37°

If f(x)=3x^5+2x^4+5, then what is the remainder when f(x) is divided by x−1?
Answer:
The remainder is 10
Step-by-step explanation:
The find the remainder when f(x) divided by g(x), find the value of x when g(x) = 0, then substitute it in f to find the value of the remainder
∵ f(x) = 3[tex]x^{5}[/tex] + 2[tex]x^{4}[/tex] + 5
∵ f(x) is divided by x - 1
∴ g(x) = x - 1
→ Equate g(x) by 0 to find x
∵ g(x) = 0
∴ x - 1 = 0
→ Add 1 to both sides
∵ x - 1 + 1 = 0 + 1
∴ x = 1
→ Substitute x in f by 1
∵ f(1) = 3[tex](1)^{5}[/tex] + 2[tex](1)^{4}[/tex] + 5
∴ f(1) = 3(1) + 2(1) + 5
∴ f(1) = 3 + 2 + 5
∴ f(1) = 10
∵ The remainder is the value of f(1)
∴ The remainder is 10

Reagan needs to sew a 1346 centimeters fringe around the edge of the bed spring.
Given that, Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters.
What is the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
Now, the perimeter = 2(238+435)
= 2×673
= 1346 centimeters
Therefore, Reagan needs to sew a 1346 centimeters fringe around the edge of the bed spring.

a semigroup which has a left identity element and in which every element has a right inverse is a group
Element and in which every element has a right inverse is a group?
Now, If both the identity and the inverse are of the same side, this is simple. For, instead of the above, say every element has a left inverse. For a∈G denote this left inverse by a−1.
Then(aa−1)(aa−1)=a(a−1a)a−1=aa−1
and we can use the fact that
cc=c
⟹c=1
to get that inverses are in fact two-sided: aa−1=1
From which it follows that
a=1⋅
a=(aa−1)a=a(a−1a)=a⋅
1 as desired. But in the scenario given we cannot use cc=c⟹c=1, and I can see no other way to prove this.
