Step-by-step explanation:

15+12x=13x+5

we move all terms to the left :

15+12x-(13x+5)=0

We get rid of parentheses

12x-13x-5+15=0

We add all the numbers together , and all the variables

-1x+10=0

We move all terms containing x to the left , all other terms to the right

-x = -10

x = -10/-1

x= +10

Explanation

The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.

(angle ABD) + (angle DBC) = 180

(134) + (2x) = 180

2x = 180-134

2x = 46

x = 46/2

x = 23

Answer: x=23 and the angle relation used was supplementary angles

Step-by-step explanation:

first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.

Answer:

4

Step-by-step explanation:

Substituting into the slope formula,

\(\frac{-3-1}{2-3}=4\)

Answer:

Step-by-step explanation:

(3,1) and (2,-3)

Use the slope formula.

Slope:

\(\longrightarrow \sf{\dfrac{y_2-y_1}{x_2-x_1} }\)

\(\sf{y_2=(-3)}\\\\\sf{y_1=1}\\\\\sf{x_2=2}\\\\\sf{x_1=3}\)

\(\sf{\dfrac{(-3)-1}{2-3}}=\sf{\dfrac{-4}{-1} }=\boxed{\sf{4}}\)

Therefore, the slope is 4, which is the correct answer.

Answer:

x=15/8; x ≈ 1.88

Step-by-step explanation:

cross products

15=8x

Divide both sides by 8

x = 1.875 = 15/8

x ≈ 1.88

5.D

Step-by-step explanation:

for question 1

Area of Base B =45×25 = 1125 cm²

perimeter of base P = 2(45+25) = 140 cm

Height = 15 cm

Using the formula

Surface area = 2B + Ph

A = 2×1125 + 140×15= 4350 cm²

Voume = Bh = 1125×15= 16875 cm³

For question 2,

Area of base = 7× 5/2= 17.5 cm²

Perimeter of base = (7+7+7) = 21 cm

Surface area = 2B + Ph

Surface area of prism = 2×17.5+ 21×10 = 245cm²

Volume = Bh = 17.5×10 = 175 cm³

Answer: $17

Step-by-step explanation:

5n+2 is the equation we start off with.

He plays 3 games, and since n represents the number of games bowled, we subsitute n with 3.

Our equation looks like this:

5(3)+2

If you solve the equation, you get:

5(3)+2

=15+2

=17

The answer is $17.

The correct statement is a. There are 1,000,000 milliliters in a kiloliter.

A kiloliter is a unit of volume equal to 1,000 liters. One liter is equal to 1,000 milliliters. Therefore, one kiloliter is equal to 1,000 x 1,000 = 1,000,000 milliliters.

Answer:

The first graph is correct.

Step-by-step explanation:

After 4 days, there are 22 rose blooms left -------(4, 22)

and after 8 days, there are 10 rose blooms left -----(8 , 10)

Equation of straight line:

y =ax +b

input (4, 22) and (8, 10)

22 = 4a + b  ----(1)

10 = 8a +b  ------(2)

solve to find a , b

(2) - (1)

-12 = 4a, a= -3

find b, b = 34

Equation is : y= -3x + 34

When you set x = 0, y is 34.

The first graph is correct.

Answer:

on mine answer B was correct

Step-by-step explanation:

Answer:

The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.

Substituting the given values, we get:

V = (1/3) x 3.14 x 9^2 x 16

Calculating this expression gives us:

V = 1810.08 cubic inches

Rounding to the nearest hundredth gives us:

V ≈ 1810.08 cubic inches (rounded to two decimal places)

Therefore, the volume of the cone is approximately 1810.08 cubic inches.

Answer:

1363.04

Step-by-step explanation:

V = (1/3) * 3.14 * 9^2 * 16

Simplifying:

V ≈ 1363.04 cubic inches

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.
