Answer:

AC = 40

Step-by-step explanation:

AC and BD are equal to each other in length. So:

4x-4 = 3x+7

Now you solve for x. Add 4 to each side.

4x= 3x + 11

Then subtract 3x from both sides.

X = 11. There you have X, now you plug 11 in for x in the AC= 3x+7

3(11) + 7 = AC

33 + 7 = AC

40 = AC

Answer:

A and C

Step-by-step explanation:

For any relation to be considered a function, each domain value (x-value) must have exactly one range value (y-value). If a relation contains an x-value that has two or more y-value related/mapped to it, the relation is not a function.

Let's examine each option given.

Option A: each x-value has exactly one y-value related or assigned to it. Therefore, the relation is A FUNCTION.

Option B: the x-value, 4, has two y-values, 12 and 15 assigned to it. Therefore, the relation is NOT A FUNCTION.

Option C: each x-value has exactly one y-value related or assigned to it. Therefore, the relation is A FUNCTION.

Option D: the x-value, 1, has two y-values, -1 and 1 assigned to it. Also, x-value, 3, has two y-values, 2 and -2 assigned to it. Therefore, the relation is NOT A FUNCTION.

Answer:

4 divided by 2/3 (4 ÷ 2/3) = 6

Step-by-step explanation:

When you divide one number by another , this is the same as multiplying that one number by the reciprocal of that other number. So a/b = a × 1/b = a × b^-1.

Also a reciprocal is the same as taking something to the power of -1.

When you take the reciprocal of a fraction, just flip the numerator, and denominator.

b^-1 = 1/b.

b^-n = 1/b^n.

(a/b)^-1 = b/a

a/b^-1 = ab

Therefore 4 / (2/3) = 4 × 3/2 = 12/2 = 6.

Answer:

He can buy 5 pounds of peaches.

Step-by-step explanation:

2 pomegranates cost $3.18 so, subtract that from $10.00 and you get $6.82. Multiply the different number of pounds with the cost per pound until you go over $6.82. Then go back a pound and multiply. 5 pounds times $1.19 equals $5.95.

Answer:

Step-by-step explanation:

Step one:

given

selling price = $48

discount is 50%

tax= 4.5%

Step two:

let us first compute the amount in discount

=50/100*48

=0.5*48

=$24

also, let us compute the tax added

=4.5/100*48

=0.045*48

=$2.16

The total amount Garry has to pay is

=48-24+2.16

=$26.16

Step three:

If he has $25, he cannot afford the video game, he will have a deficit of $1.16

Answer: Gary will have to pay $25.08 in all, and if he has exactly $25, he can't afford to purchase the game because he only has $25, and he has to pay $25.08. $25.08 is more than $25, so he can't afford the game.

Step-by-step explanation:

First, subtract the $48 and 50% to find how much the video game costs.

So, $48-50%=24

Then, add the price of the video game, $24, to the 4.5% tax.

24+4.5%=25.08

Thus, Gary will need to pay $25.08 in all.

Answer:

[tex]\boxed {\boxed {\sf m= -\frac{2}{7}}}[/tex]

Step-by-step explanation:

The slope of a line can be found using the following formula:

[tex]m=\frac{y_2-y_2}{x_2-x_1}[/tex]

Where (x₁,y₁) and (x₂,y₂) are the points on the line.

We are given the points (12,7) and (5,9). Therefore:

[tex]x_1=12\\y_1=7\\\\x_2=5 \\y_2=9[/tex]

Substitute the values into the formula.

[tex]m=\frac{9-7}{5-12}[/tex]

Solve the numerator.

[tex]m=\frac{2}{5-12}[/tex]

Solve the denominator.

[tex]m=\frac{2}{-7}[/tex]

This fraction cannot be reduced further, so it is the answer.

The slope of the line is -2/7

Answer:

x²-9x+14

Answer:5c+4

Step-by-step explanation:

Answer:

The answer is 20 feet by 20 feet. Let's solve the equation: (x – 8)^2 = 144. (x - 8)^2 = 12^2. Since a^2 = b^2 is the same as a = b, then (x - 8)^2 = 12^2 can be simplified to: x - 8 = 12. Now, solve for x. x = 8 + 12. x = 20. Therefore, the dimensions of the original lawn were 20 feet by 20 feet.

Answer:

The coach's statement is not misleading because her average strikeouts  is 7.

Where as the coach also tells that it is 7.  

Step-by-step explanation:

The average is taken out by adding the observations and dividing by the total number of observations.

X`= ∑x/n     where n is the number of observations.

Average = 7 + 14 + 6 + 4 +5 +6 /6

Average = 42/6= 7

The coach's statement is not misleading because her average strikeouts  is 7.

Where as the coach also tells that it is 7.  

Answer:

n= -3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4n+2=6(

3

n−

2

)

4n+2=(6)(

1

3

n)+(6)(

−2

3

)(Distribute)

4n+2=2n+−4

4n+2=2n−4

Step 2: Subtract 2n from both sides.

4n+2−2n=2n−4−2n

2n+2=−4

Step 3: Subtract 2 from both sides.

2n+2−2=−4−2

2n=−6

Step 4: Divide both sides by 2.

2n

2

=

−6

2

n=−3

Answer:

n = -3

Step-by-step explanation:

The first step you want to do is try to get rid of those parenthesis and to do that you want to distribute the 6 into 1/3n and 2/3 and you get

4n + 2 = [tex]\frac{6}{3}[/tex]n - [tex]\frac{12}{3}[/tex]

that can be simplified to

4n + 2 = 2n - 4

subtract 2n from both sides and you get

2n + 2 = -4

subtract 2 from both sides

2n = -6

divide both sides by 2 you get

n = -3

Answer:

The mean.

Step-by-step explanation:

The mean because 50 is a lot bigger number than the numbers in the list.

The median (the middle number in an ordered list) would still be 15. Also the mode (15) will also stay the same.

The original mean = sum of the 6 numbers divided  by 6

= 92/5 = 15.3.

When 50 is added the mean is (92 + 50) / 7 =  20.3.

Answer:

The mean

Step-by-step explanation:

Because mean is the main measure of center that we solve first before solving the others

Answer: weight of elephant has smaller percent error.

Step-by-step explanation:

Percent error = [tex]\dfrac{|\text{estimated value -actual value}|}{\text{actual value}}]\times100[/tex]

Estimated weight of elephant  =  10,000 pounds

Actual weight of elephant = 12,400 pounds

Percent error of weight = [tex]\dfrac{|12400-10000|}{12400}\times100\%\approx19.35\%[/tex]

Estimated weight of hippopotamus  =  2,500 pounds

Actual weight of hippopotamus = 3,600 pounds

Percent error of weight = [tex]\dfrac{|2500-3600|}{3600}\times100\%\approx30.55\%[/tex]

Since 19.35 < 30.55

hence, weight of elephant has smaller percent error.
