There is a bag with only red marbles and blue marbles.

The probability of randomly choosing a red marble is 2/7







There are 16 red marbles in the bag and each is equally likely to be chosen.

Work out how many marbles in total there must be.

Answer:

we conclude that:

[tex]g\left(x\right)\:-\:h\left(x\right)\:=\:2x^2\:-\:3x[/tex]

Step-by-step explanation:

Given

We have to determine [tex]g\left(x\right)\:-\:h\left(x\right)\:=\:2x^2\:-\:3x[/tex]

so

[tex]g\left(x\right)\:-\:h\left(x\right)\:=\:2x^2\:-\:3x[/tex]

Thus we conclude that:

[tex]g\left(x\right)\:-\:h\left(x\right)\:=\:2x^2\:-\:3x[/tex]

Answer:

40.9ft

Step-by-step explanation:

14+8+10+8.9 = 40.9

bottom side is 14 because the shape on the left is a rectangle so it will have 10 ft on the bottom as well as top that you have to add on top of the 4ft from the triangle.

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.

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.

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.

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°

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]

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

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.
