Andre led his baseball league in home runs last year. This year he hit 25% fewer home runs than he did last year.

If y represents the number of home runs Andre hit last year, which two of the following expressions can be used to calculate the number of home runs he hit this year?

Answer:

n = 28°

Step-by-step explanation:

The angle at the centre is twice the angle on the circle subtended on the same arc.

Also angles subtended on the same arc are congruent , thus

m = n

Then

35 + m = [tex]\frac{1}{2}[/tex] (98 + n ) ← multiply both sides by 2 to clear the fraction

70 + 2m = 98 + n , but since m = n, then

70 + 2m = 98 + m ( subtract m from both sides )

70 + m = 98 ( subtract 70 from both sides )

m = 14 and n = 28

Answer:

I. Not a function

II. Not a function

III. Yes, function

IIII. Yep!

(I messed up the numbering in the explanations, sorry 3 is 4 and 4 is 3)

Step-by-step explanation:

Hi!

For a function, every x value must have exactly 1 y value.

f(2) can't equal both 0 and 10. It can only equal 0 or 10. So, because of this, we have a test called the vertical line test. Basically, you drag a line through a graph, and if there is any x value that goes to two (or more) different y-values, then that graph is not the graph of the function.

Let me try to give a practical explanation.

I.

In this graph, everything looks fine until we reach x=6. (I'm assuming the graph goes by ones). Do you see the problem? Yep! x has two different y values.

y= 4 and y= 6.

So, this isn't a function. Why? Because there are two y values for each x value (aka, this doesn't pass the V.L.T)

II.

(1,2), (2,5) , (3,8) , (2,-5) (1,-2)

We have two groups of problem points.

(2,5) and (2,-5) and (1,2) and (1,-2)

Here, each x value goes to a different y value. Therefore, this isn't a function

III. y=x^2

This is your typical parabola. See the graph that I attached.

Notice that -2 and 2 both go to 4. Two different x-values going to the same y-value is fine, but one x can't go to to different y values.

IIII.

(-4,1) , (0,3) , (4,5) , (6,6)

Check 1: Does any x-value go to multiple y values? Nope! So, this is a function.

Here you go mate

step 1

(-25)/(-5)

step 2

(-25)/(-5)  divide the equation by 5

answer

=5

Answer: 5

Step-by-step explanation:

Multiplying or dividing a negative by a negative results in a positive.

[tex](-10)/(-2)=5[/tex]

Multiplying or dividing a negative by a positive results in a negative.

[tex](-10)/(2)=-5[/tex]

Multiplying or dividing a positive by a negative results in a negative.

[tex](10)/(-2)=-5[/tex]

Multiplying or dividing a positive by a positive results in a positive.

[tex](10)/(2)=5[/tex]

Thus, because -25 and -5 are both negatives, the answer must be positive.

Step-by-step explanation:

The average number of cars sold for entire 8 days is $33250.

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

Given that, a new cars salesperson, sold an average of $28,000 per day for the first 5 days she worked.

So, number of cars sold for 5 days =28,000×5

= 140000

The next 3 days she worked, she sold an average of $42,000.

Number of cars sold for 3 days

= 42,000×3

= 126000

So, average of 8 days =(140000+126000)/8

= 266000/8

= 33250

Therefore, the average number of cars sold for entire 8 days is $33250.

Answer:

1-1/4 cups (1 and 1/4 cups) or 1.25 cups

Step-by-step explanation:

To find the answer you need to take the total volume (5-5/8 cups) and divide it by the number of bottles you have:

5-5/8 divided by 4-1/2

There are two easy ways to do this: you can convert the mixed fractions into decimal form (A) or into improper fractions (B).

A)

First, convert to decimal form:

5-5/8 = 5.625 and 4-1/2 = 4.5

Then, you divide them:

5.625 / 4.5 = 1.25 (converted back to fraction form, if thats what you need, is 1-1/4)

B)

First, convert to mixed numbers:

5-5/8 = 45/8 and 4-1/2 =9/2

Then, you divide them:

45/8  /  9/2

When you divide fractions, you multiply by the inverse of the number you're dividing by (that means swapping the numerator and denominator):

45/8  *  2/9  =  90/72 (converted back to a mixed fraction, this equals 1-1/4)

Answer:

The three angles are 40°, 75°, 65°

Step-by-step explanation:

Assume that the first angle is x

∵ The second angle is 35° more than the first angle

∴ The second angle is x + 35

∵ The third angle is 25° more than the first angle

∴ The third angle is x + 25

∵ The sum of the angles of a triangle is 180°

→ Add the three angles and equate the sum by 180°

∵ x + x + 35 + x + 25 = 180

→ Add the like terms in the left side

∴ (x + x + x) + (35 + 25) = 180

∴ 3x + 60 = 180

→ Subtract 60 from both sides

∴ 3x + 60 - 60 = 180 - 60

∴ 3x = 120

→ Divide both sides by 3 to find x

∴ x = 40

→ Find each angle by substitute x by 40

∵ First angle = x

∴ The first angle = 40°

∵ Second angle = x + 35

∴ The second angle = 40 + 35 = 75°

∵ Second angle = x + 35

∴ The third angle = 40 + 25 = 65°

∴ The three angles are 40°, 75°, 65°

Responder:

125 pesos

Explicación paso a paso:

Dado el ingreso total l (v) obtenido de la venta de lápices por la función

Yo (v) = - 2v ^ 2 + 500v

v es el precio de venta de cada lápiz

Para que el ingreso total sea máximo, entonces dI / dv debe ser cero, es decir, dI / dv = 0

dI / dv = -4v + 500

Dado que dI / dv = 0

0 = -4v + 500

4v = 500

Dividir entre 4

4v / 4 = 500/4

v = 125

De ahí que el precio de venta de cada lápiz sea para que el ingreso total sea máximo es de 125 pesos

Step-by-step explanation:

It is given that,

Sam opened a savings account with a deposit of $50. Every month after that, he  deposited $20 more.

It is not a proportional relationship. As initial amount was $50 and every month he deposited $20 more. The ratio is not constant for the deposited amounts.

To make the relationship proportional, he must start with zero balance and then should have deposited $20 every month.

Answer:

Rob.

Step-by-step explanation:

If we take Eric's unit rate and multiply the denominator by two, it will be 14 minutes. Rob's denominator is also 14 minutes. This makes it easier on ourselves. If we multiply the bottom number we also have to multiply the top. So, on Eric's unit rate, we will take the 3 pages and mltiply it by 2 to get 6. 6 is less than 8, so Rob takes the win.

Answer:

12 blue marbles

60 clear marbles

Step-by-step explanation:

From the information given:

Let the red marble be = r

the blue marble = b;  & the clear marbles be c

April has five times as many clear marbles as blue marbles.

i.e

5c as b

She has 4 times as many blue marbles as red marbles;

i.e.  4b as r

She has 3 red marbles

i.e. r = 3

If r = 3

Then; 4 times as many blue as r will be:

= 4 × 3

= 12 blue marbles

If b = 12; then 5 times as many clear marbles as blue marbles will be:

= 5 × 12

= 60 clear marbles

Answer:

The value of k is -4.

Step-by-step explanation:

In order to find the value of k, you have to substitite x = -1/2 into the equation :

[tex]2 {x}^{2} - 7x + k = 0[/tex]

[tex]let \: x = - \frac{1}{2} [/tex]

[tex]2 {( - \frac{1}{2} )}^{2} - 7( - \frac{1}{2} ) + k = 0[/tex]

[tex]2( \frac{1}{4} ) + \frac{7}{2} + k = 0[/tex]

[tex] \frac{1}{2} + \frac{7}{2} + k = 0[/tex]

[tex]4 + k = 0[/tex]
