you start at (1,7). you move left 1 unit and down 6 unit

Answer:

Step-by-step explanation:

Use a distributive property.

Distributive property:

A(B+C)=AB+AC

A(B-C)=AB-AC

First, expand by distributive property from multiply the numbers from left to right.

-9j=-9(j-20)

-9(j-20)

-9*j=-9j

9*20=180

=-9j+180

-9j=-9j+180

Add by 9j from both sides.

-9j+9j=-9j+180+9j

Solve.

0=180

No solution.

Therefore, the correct answer is A. no solution.

Step-by-step explanation:

Answer: 9, 144, 225, 10,000

Step-by-step explanation:

9=3x3

144=12x12

225=15x15

10,000=100x100

Answer:

A = 15

B = 3

Step-by-step explanation:

Since Team A has 12 more points than team B, then,

A - 12 = B

A = B + 12 ( equation 1 )

team A has 5 times as many points as team B, so,

5B = A. ( equation 2 )

Substitute equation 1 into equation 2

A = B + 12

5B = B + 12

5B - B = 12

4B = 12

B = 3

we'll substitute the answer into equation 2

5B = A

5(3) = A

A = 15

I hope this helps :D

Find the mass:

Answer:

3619.1 grams (nearest tenth)

Step-by-step explanation:

Volume of a cylinder

[tex]V=\pi r^2 h[/tex]

where:

The radius of a circle is half its diameter.

Find the volumes of the external and internal cylinders by substituting the given values into the formula for volume of a cylinder:

[tex]\implies \textsf{Volume of the external cylinder}&=\pi \cdot 5^2 \cdot 16=400 \pi \; \sf cm^3[/tex]

[tex]\implies \textsf{Volume of the internal cylinder}&=\pi \cdot 4^2 \cdot 16=256 \pi \; \sf cm^3[/tex]

Find the volume of the cylindrical hollow metal pipe by subtracting the volume of the internal cylinder from the volume of the external cylinder:

[tex]\begin{aligned}\implies \textsf{Volume of the metal pipe}&=\sf Volume_{external}-Volume_{internal}\\&=400 \pi - 256 \pi\\& = 144 \pi \sf \; cm^3\end{aligned}[/tex]

Density formula

[tex]\rho=\dfrac{m}{V}[/tex]

where:

Given:

Substitute the given values of density and the found volume into the density formula and solve for m:

[tex]\begin{aligned}\implies \rho&=\dfrac{m}{V}\\8&=\dfrac{m}{144 \pi}\\m&=8 \cdot 144\pi\\m&=1152 \pi \\m&=3619.11473...\\m&=3619.1\; \sf g \;(nearest\;tenth)\end{aligned}[/tex]

Therefore, the mass of the pipe is 3619.1 grams (nearest tenth).

Note: I have used the exact value of π (not a rounded value).

There are 85 flowers.

There are 25 roses, 45 tulips, an 15 roses.

What are all 3 of these divisible by?

5!

That means that there will be 5 bouquets.

Let's divide each number by 5 to find out how many of each type of flower is in each bouquet.

25/5 = 5

5 roses in each bouquet

45/5 = 9

9 tulips in each bouquet

15/5 = 3

3 snapdragons in each bouquet

5 + 9 + 3 = 17

There are a total of 17 flowers in each bouquet.

Out of those 17 flowers, 3 are snapdragons.

Answer:

3 seconds

Step-by-step explanation:

The height of the rocket when it hits the ground will be zero meters.

Therefore, set the equation to zero and solve for t by using the quadratic formula.

Quadratic Formula

[tex]x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when }\:ax^2+bx+c=0[/tex]

Given equation:

[tex]-4.9t^2+14t+2.1=0[/tex]

Therefore:

[tex]a=-4.9, \quad b=14, \quad c=2.1[/tex]

Substitute the values into the quadratic formula:

[tex]\implies t=\dfrac{-14 \pm \sqrt{14^2-4(-4.9)(2.1)}}{2(-4.9)}[/tex]

[tex]\implies t=\dfrac{-14 \pm \sqrt{196+41.16}}{-9.8}[/tex]

[tex]\implies t=\dfrac{-14 \pm \sqrt{237.16}}{-9.8}[/tex]

[tex]\implies t=\dfrac{-14 \pm15.4}{-9.8}[/tex]

Therefore:

[tex]\implies t=\dfrac{-14 +15.4}{-9.8}=\dfrac{1.4}{-9.8}=-\dfrac{1}{7}[/tex]

[tex]\implies t=\dfrac{-14-15.4}{-9.8}=\dfrac{-29.4}{-9.8}=3[/tex]

As time is positive, t = 3 s only.

Therefore, it will take 3 seconds for the rocket to hit the ground.

The simplest radical form of the hypotenuse of the given right-angled triangle is therefore discovered to be [tex]6\sqrt{2}[/tex] units.

The Pythagorean Theorem states that the square on the hypotenuse of a right triangle is equal to the sum of the squares on the triangle's legs.

If the number or algebraic expression under the radical has no factors that are perfect nth powers, then the radical is said to be in its simplest radical form.

The given right angled triangle has sides 6 units each.

We need to determine the hypotenuse using the Pythagorean theorem.

Hypotenuse = [tex]\sqrt{(side 1)^{2} + side 2)^{2} }[/tex]

                      [tex]=\sqrt{6^{2} + 6^{2} } \\\\= \sqrt{72}\\ \\= 6\sqrt{2}[/tex]

The number of seats in Section A is 26000 ,The number of seats in Section B is 14800 and, The number of seats in Section C is 11200.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7.

Let the number of seats in Section A is "a".

Let the number of seats in Section B is "b".

and, Let the number of seats in Section C is "c".

Now using the statement "stadium has 52,000 seats"

we can make equation: a + b + c = 52000  

Now using the statement "Seats sell for $28 in Section A, $24 in Section B, and $20 in Section C" and "stadium takes in$1,307,200 from each sold out event".

we can make equation: 28a + 24b + 20c = $1,307,200

Now using the statement "he number of seats in Section A equals the total number of seats in Sections b and C"

we can make equation: a = b + c

Solving these three equations. We get,

a = 26000 , b = 14800 and c = 11200

The possible values of X are that if n is even X can takes even integers from [-n, n], and if n is odd, X can takes odd integers from [-n, n]

To solve this question, we can use X to represents the difference between the number of heads and the number of tails obtained when a coin is tossed X times, the possible values of X are now obtained below:

Let H be the no. of heads and T be the no. of tails, since the coin is tossed n times, we have:

H+T=n

now, X = H-T ,

X=H-(n-H)

X=2H-n

Now,

H takes values {0,1,2,3 ......,n-2, n-1,n}

2H takes values {0,2,4,6,.....,2n-4,2n-2,2n}

2H - n takes values {-n,-(n-2),-(n-4), -(n-6),.............,n-4, n-2,n}

X takes values {-n,-(n-2), -(n-4),-(n-6),.............,n-4, n-2, n}
