Is (-5) x (-4) is negative or positive?
Answer:

Answer:

0.434 seconds

Step-by-step explanation:

Distance = 60 feets 6 inches

Speed of baseball = 95mph

Time taken : distance / speed

6 inches = 0.5 feets

60 feet 6 inches = 60.5 feets

Convert 60 feet 6 inches to miles

1 mile = 5280 feets

x = 60.5 feets

5280x = 60.5

x = 60.5 / 5280

x = 0.0114583 miles

Hence,

60.5 feets = 0.0114583 miles

Hence,

Time taken = 0.0114583 miles / 95 mph

Time taken = 0.0001206 hour

Converting to seconds :

0.0001206 * 3600

= 0.4342105 seconds

0.434 seconds

Answer:

B. 11

Step-by-step explanation:

Valorie made five times more baskets, so if you replace the V in the equation with how many baskets she made (55), it would look like 55=5n. Divide 55 and the n by five to get rid the five in the equation. 11=n. Thus, the answer is B.

Answer:

30 units²

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

Here

b is the horizontal measure between 2 red points, that is 6

h is the vertical measure from the lower left point to the other horizontal line, that is 5, then

A = 6 × 5 = 30 units²

Answer:

[tex]\frac{17\pi }{6}[/tex]

Step-by-step explanation:

To convert from degrees to radians

radian = degree measure [tex]\frac{\pi }{180}[/tex]

           = 510 × [tex]\frac{\pi }{180}[/tex]

           = [tex]\frac{51\pi }{18}[/tex]

           = [tex]\frac{17\pi }{6}[/tex] radians

510 degrees is equal to (17π / 6) radians, which is determined by using the fact that 180 degrees is equal to π radians.

The given angle is  510°.

To convert 510 degrees to radians, we can use the fact that π radians is equivalent to 180 degrees.

First, we convert 510 degrees to radians by setting up a proportion:

180 degrees = π radians

510 degrees = x radians

Solving for x, we find:

x = (510 degrees) * (π radians / 180 degrees)

Simplifying the expression, we have:

x = (17π / 6) radians

Therefore, 510 degrees is equal to (17π / 6) radians.

Answer:

(-11)3 x r3 x 63

Step-by-step explanation:

Answer:

Step-by-step explanation:

y = 25x +100

y- is the total money spent on the phone

x-is the number of months you had service

the relationship between x and y is proportional ( if x grows, y grows)

For example: after 2 months you would had payed $100 for the phone + the $25 each of the 2 months. y= 25*2 +100 = $150

Answer:

(1, 0.5)

Step-by-step explanation:

From the graph attached,

x-values are representing the number of games downloaded,

y - values are representing the total cost.

Unit rate means rate of 1 game downloaded.

If we represent this in terms of coordinates,

x- value (game downloaded) = 1

y - value (price of one game download) = $0.5

Therefore, point (1, 0.5) will represent the unit rate.

Option (2) on the top row will be the answer.

Answer:

Step-by-step explanation:

you are given the slope m = -6/5 and one point (x1,y1) as (-5,-2)

next use  the point-slope formula [y-y1 = m(x-x1) ] and plug in the point and the slope

y-(-2) = -6/5(x-(-2))    ( they are making this tuff with all the minus signs :/ )

y+2 = -6/5(x+2)         ( nice looks better, distribute the -6/5 )

y + 2 = -6/5x -12/5    (move the 2 over )

y = -6/5x - 12/5 -2      ( 2 = 10/5 )

y = -6/5x -12/5 - 10/5    (add the fractions )

y = -6/5x -22/5    

that's in the form of the slope-intercept now  [ y = mx + b ] so you're done :)

The coordinates of the midpoint are (-2,-1)

Step-by-step explanation:

The Midpoint of a Segment

Given a segment defined by points (x1,y1) and (x2,y2), the coordinates of the midpoint (xm,ym) are calculated as follows:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

We have the endpoints (0,4) and (-4,-6):

[tex]\displaystyle x_m=\frac{0-4}{2}[/tex]

[tex]\displaystyle x_m=\frac{-4}{2}=-2[/tex]

[tex]\displaystyle y_m=\frac{4-6}{2}[/tex]

[tex]\displaystyle y_m=\frac{-2}{2}=-1[/tex]

The coordinates of the midpoint are (-2,-1)

Answer:

Step-by-step explanation:

So first we do (x^5)^2 which we know is just x^10 because of exponents of powers I believe it's called, basically you just multiply the two powers.

Then you do the bottom half which is x^3 * x^7 and that equals x^10 because of the product of exponent rule,

Then we do x^10/x^10 which = 1 because the same number over the same number is always 1.

Answer:

Solving the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex] the answer is 1

Step-by-step explanation:

We need to solve the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex]

We know that exponent rule: [tex](a^m)^n=a^{m*n}[/tex]

Applying this rule in numerator

[tex]\frac{(x^5)^2}{(x^7)(x^3)}\\=\frac{(x^{5*2})}{(x^7)(x^3)}\\=\frac{(x^{10})}{(x^7)(x^3)}[/tex]

We know the exponent rule: [tex](a^m).(a^n)=a^{m+n}[/tex]

[tex]=\frac{(x^{10})}{x^{7+3}}\\=\frac{(x^{10})}{x^{10}}[/tex]

Now, using the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex]

[tex]=x^{10-10}\\=x^0[/tex]

We know that [tex]a^0=1[/tex]

So, [tex]x^0=1[/tex]

Solving the expression: [tex]\frac{(x^5)^2}{(x^7)(x^3)}[/tex] the answer is 1

2. 70%

Step-by-step explanation:

Given :

Nathan smiled at 50 people one day and recorded that 36 people smiled back at him.

To Find :

How many people should Nathan expect to return a smile if he smiles at 650 people over a period of time.

Solution :

Ratio of people smiled by total number of people is :

[tex]R = \dfrac{36}{50}[/tex]

Now, it is given that we have to use the given conditions.

Therefore, ratio will be same :

[tex]\dfrac{s}{650}=\dfrac{36}{50}\\\\s = \dfrac{36}{50}\times 650\\\\s = 468[/tex]

Therefore, number of smiles Nathan expect to return is 468.
