Answer 1

Answer:

2*5

Step-by-step explanation:

when youre dividing with powers you have to subtract them so 2*5-2*4=2*1. When the power is in brackets you multiply the whole power. So 2*1 x 5 = 2*5.

The gym has 4 times as many baseballs than basketballs the gym has 25 total balls how many more baseballs than basket balls does the gym have

Answers

Let [tex]b[/tex] be the number of baseball and [tex]k[/tex] be the number of basket ball.

We have the following system:

[tex]\begin{cases}b=4k\\b+k=25\end{cases}[/tex]

Substitute the first equation into the second:

[tex]4k+k=25 \iff 5k=25 \iff k=5[/tex]

which yields

[tex]b=4k=4\cdot 5 = 20[/tex]

So, there are 20 baseballs and 5 basketballs, meaning that there are 15 more baseballs than basketballs.

C. 1.167 units
D. 4.189 units
SUBMIT

Answers

The approximate arc length is,

⇒ s = 3.665 units

What is mean by Circle?

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Since, We know that;

The arc length (s) is given by,

⇒ s = r·θ

Here, We have;

r = 1

θ = 7π / 6

Hence, We get;

s = 1 × 7π/6

s = 3.665 units

Thus, The approximate arc length is,

⇒ s = 3.665 units

You have a fraction of 13/20. The 13 is the amount of children that prefer fries out of 20 children in total. Multiply the 20 by 5 and you get 100. Then multiply the 13 by 5 since what you do to the bottom you gotta do to the top and you get 65/100. Next there are 13 adults that prefer fries over 25. 25 times 4 is equal to 100 and what you do to the top you gotta do to the bottom. 13 times 4 is 52. 65/100 children prefer fries and 52/100 adults prefer fries. The first box you put 65, the second box you put 52, and the third you put more likely

The first one is 13/20 second one is 13/25 and the third is equally likely

Some people advise that in very cold weather, you should keep the gas tank in your car more than half full. Lou's car had 6.8 gallons in the 15-gallon tank on the coldest day of the year. Lou filled the tank with gas that cost $3.90 per gallon. How much did Lou spend on gas?

Answers

Answer: You have the following information given in the problem above:

- Lou filled the tank with gas that cost $3.80 per gallon.

- Lou's car had 5.9 gallons in the 13-gallon tank.

2. Therefore, if he filled the tank, you can calculate the total amount of money Lou spent, by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.

3. Then, the result is:

$26.98

The answer is 27.98

If you divide a polynomial f(x) by the factor (x - 4), the remainder will be equal to f(-4). true or false ?

Answers

Answer:

FALSE

Step-by-step explanation:

Given the polynomial f(x) divided by x-4

To check whether the remainder will be equal to f(-4), we need to get whether the value of x is -4 if we set x-4 to zero as shown;

x- 4 = 0

Add 4 to both sides

x - 4 + 4 = 0+4

x = 4

Since the value of x is 4 not -4 hence the remainder will NOT be equal to f(-4). The answer is false

If isosceles triangle ABC has a 130° angle at vertex B, which statement must be true?
O mZA= 15° and mzC= 35
O mZA+ mZB = 155°
O mZA+ mzC = 60
OMZA= 20° and m2C=30

Answers

Answer:

Option B m<ZA+m<ZB = 155° is correct option.

Step-by-step explanation:

We know that sum of angles of triangle is equal to 180°

And Isosceles triangle, 2 angles are same

So, let Angle 1 = x

Angle 2 = x

Angle 3 = 130°

Finding values of angle x

x+x+130=180

2x=180-130

2x=50

x=25

So, Angle 1 = 25 °

Angle 2 = 25°

As, angle B is greater than 90°, the sum of angles added must be greater than 90°

So, Option A, C and D can't be correct, as their sum is less than 90°

Option B m<ZA+m<ZB = 155° is correct option.

Verify:

m<ZA = 25° (as found earlier)

m<ZB = 130° (given)

So, m<ZA+m<ZB = 155°

25°+130° = 155°

The true statement about the given angles of the triangle is m∠A + m∠B = 155⁰.

Sum of angles of Isosceles triangle

The sum of angles of Isosceles triangle must add up to 180 degrees.

Base angles of the Isosceles triangle

Let the base angles = x and x

x + x + 130 = 180 (sum of angles in a triangle)

2x + 130 = 180

2x = 180 - 130

2x = 50

x = 25

Given angle B = 130°

B + A = B + C = 130 + 25 = 155°

Thus, the true statement about the given angles of the triangle is m∠A + m∠B = 155⁰.

The table for the function is,

x -3 -2 1 4 5

g(x) -14 -9 6 2 26

What is a function?

A mathematical phrase, rule, or law establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Given a function g(x) = 5x + 1

to find the values of g(x) for given values of x

when x = -3

g(x) = 5x + 1

g(-3) = 5(-3) + 1

g(-3) = -14

when x = -2

g(-2) = 5(-2) + 1

g(-2) = -9

when x = 1

g(1) = 5(1) + 1

g(1) = 6

when x = 4

g(4) = 5(4) + 1

g(4) = 21

when x = 5

g(5) = 5(5) + 1

g(5) = 26

Hence the values for g(x) are -14, -9, 6, 21, and 26 respectively.

a. 4
b. 15
c. 12
d. 18

Answers

Answer:

b. 15

Step-by-step explanation:

Given that:

There are 4 independent variables, then the subset regression total is 2⁴ = 16 attainable regression model.

However, out of these 16 regression models, 1 Model contains no predictors which only intercept 3 Model with [tex](X_1), (X_2), (X_3)[/tex], 3 Model with[tex](X_1,X_2), (X_1,X_3), (X_2,X_3)[/tex]. and 1 Model which comprises all the independent variables.

Therefore, when applying best subsets regression with a model that possesses four (4) independent variables, the number of different combinations of regression models that can be considered is 15.
