Answers

Final answer:

Miguel ran different distances on Monday and Friday. We calculate how much farther he ran on Friday than on Monday to find the difference in distance.

Explanation:

Miguel ran 1 3/10 miles on Monday. On Friday, Miguel ran 3 times as far as he did on Monday. To find out how much farther Miguel ran on Friday than on Monday, we first calculate how far he ran on Friday, which is 1 3/10 miles x 3 = 3 9/10 miles. The difference in distance is 3 9/10 - 1 3/10 = 2 6/10 miles.

Distributive property of
36+ 9y

Answers

find the greatest common factor (GCF)
in this case it would be 9

divide each term by the GCF
36 / 9 = 4
9y / 9 = y

put the two "new" terms in parenthesis and the GCF in front of it
9 (4 + y)
it could also be 9 (y + 4) because of Commutative Property of Addition
This problem in the distributive form would be 9(4+y) because the greatest common factor, or GCF, is 9. When you divide 36 by 9 you get 4 and 9 divided by 9 is one, therefore leaving the y.
To conclude the answer would be 9(4+y).

How do I find the area of the isosceles triangle?

Answers

Use the Pythagorean Theorem to find 'h'.

[tex]\sf a^2+b^2=c^2[/tex]

For right triangles, where 'a' and 'b' are the two legs and 'c' is the hypotenuse.

Divide the base by 2 to find the base length of one of the right triangles. 32/2 = 16. Now apply the Pythagorean Theorem:

[tex]\sf 16^2+b^2=20^2[/tex]

Simplify:

[tex]\sf 256+b^2=400[/tex]

Subtract 256 to both sides:

[tex]\sf b^2=144[/tex]

Take the square root of both sides:

[tex]\sf b = 12[/tex]

So the height is 12cm. Apply the formula for the area of a triangle:

[tex]\sf A=\frac{1}{2}bh[/tex]

[tex]\sf A=\frac{1}{2}(32)(12)[/tex]

[tex]\sf A=192cm^2[/tex]

John has four more nickels than dimes in his pocket, for a total of $1.25. Which equation could be used to determine the numbet of dimes, x, in his pocket?

Answers

So, you have to have your equation in terms of dimes. What you said about what he has: four more nickels than dimes in his pocket. Will help with our equation.
We know what a nickel and dime is worth. A nickel is .05 and a dime is .1
We don't know how many dimes are in his pocket, since we're trying to solve it.
.1x+(4+x).05=1.25; 
In the parenthesis, it shows how there are four more nickels. Let's solve it now.
.1x + (4+x).05=1.25
.1x + .2+ .05x = 1.25; Let's add like terms.
.15x + .2 = 1.25; Subtract .2 from both sides.
.15x= 1.05
1.05÷.15= 7 =x
There are 7 dimes in his pocket, let's check our answer.
We now know there are 11 nickels, since there are four more nickels than dimes.
11(.05) +.1(7) = 1.25
.55+ .7 = 1.25
Now that we've tried it, we know there are 7 dimes in his pocket.

A function has a constant tripling time. What type of function does this represent ?
A. Expontential decay
B. Decreasing linear
C. Increasing linear
D. Exponential growth

Answers

Answer: This represented a exponential growth function.

Step-by-step explanation:

Exponential growth is demonstrated when the rate of change of the value of any mathematical function[the change per unit of time] is proportional to the function's present value, resulting in its value at any time being an exponential function of time or becomes a function in which the time value is the exponent.

Given : A function has a constant tripling time. So it is highly increasing (exponentially) with the time i.e. the function is exponential function.


Answer: Hello mate!

A constant tripling time means that there is a time T, a quantity triples when t = T, then triples again when t = 2T, and again when t = 3T.

Then if A is the initual cuantity; we have a function of the form

f(t) = A*3^(t/T)

and you can see that:

f(0) = A

f(T) = A*3

f(2T) = A*3^2 = (A*3)*3

and so on:

This function describes an exponential growth (because f(t) increases exponentialy over time)

Find the area of each figure. Round to the nearest tenth if necessary

Answers

Divide the shape into different parts. For this on you should find the area of the square separately and then the area of the triangle separately. Then you add th two areas together to find the overall area of the shape. 
For the square, a=b*h
                         a=5.2*5.2
                         a=27.04

For the triangle, a=0.5(b*h)
                          a=0.5(7*11.2)     for the height of the triangle (11.2) add the                                                       three numbers that make up the length of                                                         that side (4+5.2+2=11.2)
                         a=0.5(78.4)
                         a=39.2
Lastly, add the areas of the triangle and the square together. 
27.04+39.2=66.24

The area of the figure is 66.24 meters squared

Use slope formula m= y2-y1/x2-x1 to find the slope of a line that passes through the points (–3, 8) and (4, –6).

Answers

Final answer:

The slope of the line passing through the points (−3, 8) and (4, −6) is calculated using the slope formula and results in a slope of −2.

Explanation:

To find the slope of the line that passes through the points (−3, 8) and (4, −6), we apply the slope formula m = (y2 − y1) / (x2 − x1). Let's designate the first point (−3, 8) as (x1, y1) and the second point (4, −6) as (x2, y2). Plugging these values into the formula, we get:

m = (−6 − 8) / (4 − (−3))

m = −14 / 7

m = −2

Therefore, the slope of the line between the two points is −2. The negative sign indicates that the line is descending from left to right.

Final answer:

To calculate the slope of a line that goes through the points (-3, 8) and (4, -6), apply the slope formula m = (y2 - y1) / (x2 - x1). After substituting the values, the slope is found to be -2.

Explanation:

To find the slope of the line that passes through the points –(3, 8) and (4, –6), we can use the slope formula, which is m = (y2 - y1) / (x2 - x1).

Using the given points, Point 1 (x1, y1) is (-3, 8) and Point 2 (x2, y2) is (4, -6). Substituting these values into the slope formula gives us:

m = (-6 - 8) / (4 - (-3))

m = (-14) / (7)

m = -2

Therefore, the slope of the line that passes through the given points is -2.

The perimeter of a sand volleyball court is 52 meters. The area is 153 square meters. What are the dimensions of the volleyball court?

Answers

Final answer:

To find the dimensions of the volleyball court, set up a system of equations using the perimeter and area formulas. Solve the equations to find the possible dimensions of the court.

Explanation:

To find the dimensions of the volleyball court, we can set up a system of equations using the given information. Let's represent the length of the court as 'l' and the width as 'w'. We know that the perimeter of a rectangle is given by the formula 2l + 2w, so we can set up the equation 2l + 2w = 52. Additionally, we know that the area of a rectangle is given by the formula lw, so we can set up the equation lw = 153.

Using these equations, we can solve for the dimensions of the volleyball court. Let's solve the first equation for l: 2l = 52 - 2w. Dividing both sides by 2 gives us l = 26 - w. Now we can substitute this value of l into the second equation: (26 - w)w = 153. Expanding this equation gives us w^2 - 26w + 153 = 0. We can solve this quadratic equation using factoring, the quadratic formula, or by graphing. After solving for w, we can substitute this value back into the equation l = 26 - w to find the length of the court.

After solving the quadratic equation, we find two possible values for the width: w = 9 and w = 17. Plugging each value into the equation l = 26 - w, we find the corresponding lengths: l = 17 and l = 9. Therefore, the possible dimensions of the volleyball court are 17m by 9m or 9m by 17m.

A minor league baseball team plays 101 games in a season. If the team won 14 more than twice as many games as they lost, how many wins and loses did the team have?

Answers

A minor league plays 101 games,
They win 14 more than twice as many as they lost.
How many wins and loses?

Okay, simple.
First, write a simple addition equation. In this case wins = w and losses = l.
l + w = 101.

Now, we have to figure out a way to make one of the terms the same term as the other, in this case we can change the terms of w to l.
l = l
w = 2l +14 (14 more than twice the amount)

Okay. So plug in the new amount for w.
l + 2l + 14 = 101. Great! we now have a simple equation. lets solve.
put similar terms together.
3l + 14 = 101
3l = 87
l = 29
So, we have 29 loses, and
w = 2(29) + 14
72 wins!
To check,
72 + 29 = 101, correct!

Hope this helps!

Your school is located at (2,−1), which is 2 blocks east and 1 block south of the center of town. To get from your house to the school, you walk 5 blocks west and 2 blocks north. a. What ordered pair corresponds to the location of your house?

Answers

Final answer:

Starting from your school's location (2,-1), by subtracting 5 from the x-coordinate for walking west, and adding 2 to the y-coordinate for walking north, the location of your house corresponds the ordered pair (-3,1).

Explanation:

Given your school is at (2,-1) and you walk 5 blocks west and 2 blocks north to reach your school, we can determine the location of your house. If we think of the coordinate system with east being positive along the x-axis and north as positive along the y-axis, then walking west (the opposite direction of positive x) means subtracting from the x-coordinate and walking north (the positive y direction) means adding to the y-coordinate.

So, starting from the school's location (2,-1), to account for your walk, subtract 5 (for walking west) from the x-coordinate, resulting in -3, and add 2 (for going north) to the y-coordinate, resulting in 1. Thus, the location of your house corresponds to the ordered pair (-3,1).
