(3−8y)⋅(−2.5)= Apply the distributive property to create an equivalent expression.
PLease helP

Answers

(3-8y)*(-2.5) = (3)*(-2.5)+(-8y)*(-2.5)
(3-8y)*(-2.5) = -7.5+20y

Distributive Property:

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

In numerical form we have:

[tex] a(b+c) =a*b +a*c [/tex]

Now let us use this property for our question:

(-2.5)(3-8y)

Here we have ,

a=(-2.5) , b=3 and c=-8y

So using distributive property here,

[tex] (-2.5)(3-8y) =(-2.5)*(3) +(-2.5)*(-8y) [/tex]

=-7.5 +20y

So answer is -7.5 +20y


a soccer field has a length of 100 yards and a width of 60 yards .which equation can you use to find the area of the soccer field

Answers

60 × 100

Since the formula for area of a rectangle is length × width, multiplying the sides will get you the area.

Hope this helps!

Final answer:

To find the area of a soccer field with a length of 100 yards and a width of 60 yards, the equation used is Area = 100 yards × 60 yards, resulting in an area of 6000 square yards.

Explanation:

To calculate the area of a soccer field with a length of 100 yards and a width of 60 yards, we can use the formula for the area of a rectangle, which is Area = length × width. In this case, we would calculate the area as follows:

Step 1: Identify the Formula

Area = length × width

Step 2: Plug in the Measurements

Area = 100 yards × 60 yards

Step 3: Calculate the Area

Area = 6000 square yards

Therefore, the equation to find the area of the soccer field is Area = 100 yards × 60 yards, giving us an area of 6000 square yards.

A mule dear can 1/4 of a mile in 25 seconds. At this rate, what expression can be used to determine how fast a mule deer runs in miles per hour

Answers

We have to find how many seconds are in one hour.
There are 60 seconds in one minute, with 60 minutes in every hour.
60×60=3600
Now, see how many 25 seconds are in 3600 seconds.
3600÷25= 144

you need four new pillows. you decide to buy neither the least expensive nor the most expensive. how much will your pillows cost? medium pillow: $18.49, large pillow: $22.69 and small pillow: $15.99 (re-worded)

Answers

Since we neither want most expensive nor least expensive, we need to go with pillow which is costing $18.49.

So total 4 pillows cost = 4*18.49
= $73.96
Considering there are only 3 options, we can deduce that the medium pillow is the pillow you decided to buy. Multiply the price of the medium pillow ($18.49) by 4 to get the final result. 
18.49

Alex has 4 less than twice the number baseball cards as leo. ginny has 12 more than three times the number of baseball cards Leo has if Alex has 128 baseball cards how many baseball cards does ginny have

Answers

Alex has 128 baseball cards, Leo has 66 cards, and ginny has 210.
Final answer:

By defining the variable 'L' for the number of baseball cards Leo has, we solve for 'L' and determine that Ginny has 210 baseball cards using the equations derived from the given information.

Explanation:

The student has asked a question that involves algebraic expressions and solving equations which is a typical middle school mathematics problem. First, let's define a variable for the number of baseball cards Leo has. Let's call this number 'L'. According to the problem, Alex has 4 less than twice the number of baseball cards as Leo, which can be expressed as 2L - 4. We know that Alex has 128 baseball cards, so we can set up the equation 2L - 4 = 128.

Now, let's solve for L:

Add 4 to both sides of the equation: 2L - 4 + 4 = 128 + 4Simplify: 2L = 132Divide both sides by 2: L = 66

Now we know Leo has 66 baseball cards. We can use this information to find out how many baseball cards Ginny has. The problem states that Ginny has 12 more than three times the number of baseball cards that Leo has. This can be expressed as 3L + 12. Since L is 66, we substitute and calculate Ginny's baseball cards:

Ginny's baseball cards: 3(66) + 12 = 198 + 12 = 210

triangle abc has vertices a(1 4) b(-2,4) c(-1,-1) . A dilation with a scale factor of 0.25 and center at the origin is applied to the triangle. what are the coordinates of B in the dilated image?

Answers

To find the new coordinates of point B after a dilation with a scale factor of 0.25, we multiply its original coordinates by the scale factor. The coordinates of B after dilation are (-0.5, 1).

Finding Coordinates after Dilation

To find the new coordinates of point B after a dilation with a scale factor of 0.25 and a center at the origin, we need to apply the dilation transformation to the original coordinates of B(-2, 4).

Dilation is performed by multiplying both the x and y coordinates by the scale factor. The formula for dilation centered at the origin (0,0) is:

(x', y') = (k * x, k * y)

Given the scale factor (k) is 0.25:

(x', y') = (0.25 * -2, 0.25 * 4)

Which simplifies to:

(x', y') = (-0.5, 1)

Therefore, the coordinates of B in the dilated image are B'(-0.5, 1).

Answers

Hi! To estimate you just have to average the probability of the computer game responding "go" when a button is pressed. For the first one, the button responded "go" 8 out of 10 times, which gives it a probability of 80%. For the second one, the probability is 32/50 or 64%, while the third one is 67/100 or 67%.

Averaging this we'll get:
[tex] \frac{0.80+0.64+0.67}{3} =0.70[/tex]

Since we're just estimating, we can choose the value closest to 70%.

Please help on #8, Due really soon!!

Answers

Answer: 72 square centimeters

-------------------------------------------------------------

Area of triangle ECD = (base)*(height)/2
Area of triangle ECD = 6*12/2
Area of triangle ECD = 72/2
Area of triangle ECD = 36 square cm

Subtract this area from the trapezoid area. This will get us the area of the parallelogram

Area of Parallelogram ABCE = (area of trapezoid ABDE) - (area of triangle ECD)
Area of Parallelogram ABCE = (180) - (36)
Area of Parallelogram ABCE = 144 square cm

The last step is to divide the area of the parallelogram in half. This is because the parallelogram is made of two congruent triangles (triangle ABE and triangle EBC). The two triangles ABE and EBC have equal areas

Area of triangle EBC = (1/2)*(area of parallelogram ABCE)
Area of triangle EBC = (1/2)*(144)
Area of triangle EBC = 72 square centimeters

what is 78 million in scientic notation?

Answers

In this problem, you are asked to write a number in scientific notation. In figures, 78 million would look like this:

78,000,000

To write this to scientific notation, you have to move the decimal point to the left until you will get a number between 1 and 10.

Here, you will have to move the decimal point 7 times to get 7.8

The exponent of the scientific notation is the number of times you moved your decimal point. Since the movement of decimal point is going to the left, you will have a positive exponent.

The scientific notation would look like this:

7.8 x 10^7

That would be 7.8 * 10^7

Answers

like terms are when numbers with and without variables can be combined. ex: 4x+6-8x+=32
you would first combine 4x and -8x because they are the same.
Like terms are terms that have the same root and coefficient. For example, 2x and 3x both have the same variable, so you can combine them (add them). 

2x + 3x = 5x

You combine the coefficients by adding them. 2 + 3 = 5.

Find the common difference of the arithmetic sequence

Answers

 arithmetic sequence is a sequence where terms or added or subtracted by the same constant.

[tex]10-6=6[/tex]

[tex]22-16=6[/tex]

both of the answers results as [tex]6[/tex], so [tex]6[/tex] is your common difference.

Answer:

6

Step-by-step explanation:

Common difference of an arithmetic progression is the difference between the preceding term and the succeeding term of the sequence.

Given the arithmetic sequence 4,10,16,22...

To calculate the common difference, first, we say let the first term be T1, second term be T2, third term be T3 and the fourth term be T4.

Taking the difference of the terms to know the common difference can be gotten as thus;

T2-T1 = T3-T2 = T4-T3 = k

The value of k must be the same for all the difference. This will give;

10-4 = 16-10 = 22-16 = 6

Since their difference gave the same value, therefore the common difference of the sequence is 6

A rectangle is drawn on a coordinate plane. Three vertices of the rectangle are points A(−4,3) , B(2,3) , and C(2,−1) . Point D is the fourth vertex of the rectangle. What is the distance from point C to point D?

Answers

coordinates of D= (-4,-1)

=> distance from point C to point D is 6 units

Answer:

Distance CD = 6

Step-by-step explanation:

In a rectangle ABCD coordinates of A(-4, 3), B(2, 3) and C(2, -1) are given.

We have to find the distance between points C and D when D is the fourth vertex of the rectangle.

Since in a rectangle length of opposite sides are equal, so AB = CD

distance between A(-4, 3) and B(2,3) = distance between points C and D

√(2+4)²+ (3-3)² = CD

CD = √6² = 6

Therefore CD = 6 is the answer.
