Answer 1

Answer:

∠ 1 = 58°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

117° is an exterior angle of the triangle, then

∠ 1 + 59° = 117° ( subtract 59° from both sides )

∠ 1 = 58°

Greyson rides his bike at a constant rate. In 30 minutes, Greyson can bike 7 miles. I need help on number 3.

Answers

Step-by-step explanation:

The answer is In the picture above

I lien ratios for problems like these.

7miles/30 minutes = x miles/105 minutes

Cross multiply
(7miles)(105 minutes) = (30 miles) (x)
735 = 30x
x = 24.5 miles

You can also divide 7 by 30 to get miles/ minute = 0.233 and then multiply that by 105 minutes

0.2333 x 105 = 24.5 miles

Part A. Write the equation 5=10x−5y in slope-intercept form.

Part B. Identify the y-intercept.

Answers

Answer:

Part A: y=2x-1

Part B: -1

PART A:

slope intercept form is y=mx + b

5=10x-5y subtract 10 both sides
-10x+5=-5y divide -5 both sides
2x-1=y

slope intercept form is y=2x-1

PART B:

In slope intercept form (y=mx+b), the y intercept is always ‘b’ therefore using the new equation the y intercept= -1

Jamie sees a sale at the Gaming Store where all games are the same price. He buys 3 video games. His sister talks him into also buying two $1.50 candy bars and a $2.00 drink for a total of $57.50. Write an equation to find the price of one video game.

Answers

Answer: 3x + 5 = 57.50

Step-by-step explanation:

Assume that the price of one video game is x. Jamie bought 3 video games so the expression will be:

= 3x

His sister talked him into buying two $1.50 candy bars and a $2.00 drink. The total of this is:

= 1.50 + 1.50 + 2.00

= $5.00

The total amount spent on both the video game and the snacks is $57.50. Equation will therefore be:

3x + 5 = 57.50

You start out with a penny that will double every day for 30 days. Find the average rate of change from day 7 to day 14. Remember that this function has already been shown to be f(x)=0.01(2)^x.

Answers

Answer:

$23.22 per day.

Step-by-step explanation:

For a general function f(x), the average rate of change between A and B (when B > A) is:

[tex]r = \frac{f(B) - f(A)}{B - A}[/tex]

In this case we know that the function is:

f(x) = 0.01*(2)^x

And we want to find the average rate of change from day 7 to day 14

Then if we use the above equation we get that the rate of change from day 7 to day 14 is:

[tex]r = \frac{0.01*(2)^{14} - 0.01*(2)^7}{14 - 7} = 23.22[/tex]

Because this equation is in dollars, we can conclude that the average rate of change between day 7 and day 14 is $23.22 per day.

An average rate of change between A and B (where B>A) for a generic function [tex]f(x)[/tex] is:

[tex]\to r=\frac{f(B)-f(A)}{B-A}\\\\[/tex]

In this situation, the function is:

[tex]\to f(x) = 0.01\times (2)^x[/tex]

And we'd like to calculate the average rate of change from day 7 to day 14.Using the aforementioned equation, we can calculate the rate of change from day 7 to day 14 as follows:

[tex]\to r=\frac{0.01\times 2^{14} -0.01 \times 2^7}{14-7}=23.22[/tex]

Since this equation is stated in dollars, we can calculate that the average rate of change between days 7 and 14 is [tex]\$23.22[/tex] each day.

Step-by-step explanation:

Given:

Length of cuboid = 14 inch

Width of cuboid = 9 inch

Height of cuboid = 11 inch

Find:

Volume of cuboid

Computation:

Volume of cuboid = Length of cuboid x Width of cuboid x Height of cuboid

Volume of cuboid = 14 inch x 9 inch x 11 inch

Volume of cuboid = 126 inch² x 11 inch

Volume of cuboid = 1,386 inch³
