You can see immediately from the graph that the range for Florida (20) is greater than that for Australia (15). Naturally 20 > 15.

Clayton has saved $5.65 in dimes and quarters. He has 10 more quarters than dimes. How many of each denomination of coins does h

Ksju [112]

Answer: Dimes: 9

Quarters :19

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations using the information given:

He has 10 more quarters than dimes

Q = D +10

Clayton has saved $5.65 in dimes and quarters

0.25 Q + 0.10 D = 5.65

Where:

Q= number of quarters

D= number of dimes

Replacing the value of Q for (D+10) in the second equation:

0.25 (D +10) + 0.10 D =5.65

0.25D + 2.5 +0.10D =5.65

0.25D + 0.10 D =5.65-2.5

0.35 D = 3.15

D = 3.15/0.35

D=9

Replacing the value of D by 13 in the first equation:

Q= D +10

Q =9 +10 =19

Distance between two points $(-3, 4)$ and $(5, -2)$ is $10$ units.

Mid-point of the line segment joining $(-1, -5)$ and $(7, 1)$ is $(3, -2)$ .

Degree of the given polynomial is $7$ .

6) Distance between two points $(x_1, y_1)$ and $(x_2, y_2)$ is:

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

So, distance between two points $(-3, 4)$ and $(5, -2)$ is:

$=\sqrt{(5-(-3))^2+(-2-4)^2}$

$=\sqrt{(8)^2+(-6)^2}$

$=\sqrt{64+36}$

$=\sqrt{100}$

$=10$

So, option D is correct.

7) Mid-point of the line segment joining $(x_1, y_1)$ and $(x_2, y_2)$ is:

$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Mid-point of the line segment joining $(-1, -5)$ and $(7, 1)$ is:

$(\frac{-1+7}{2}, \frac{-5+1}{2})$

$= (\frac{6}{2}, \frac{-4}{2})$

$= (3, -2)$

So, option A is correct.

8) Degree of a polynomial is the highest power of the variable in the polynomial.

$f(x)=3x^2-7x^4+9x^7+2x^3$

Here, the highest power of the variable is $7$ .

So, option B is correct.

If vertex A is at (-1, 2) and vertex B is at (1, 5), then vertex A' is at and vertex B' is at .

Serggg [28]

Answer:

Vertical translation is along the y axis while horizontal translation is along the x-axis.

Vertex A' is at (-1 - 3, 2 + 6) = (-4, 8)

Vertex B' is at (1 - 3, 5 + 6) = (-2, 11)
