Answers

Answer 1

The local hamburger shop sold 115 hamburgers and 345 cheeseburgers on Friday.

What is an equation?

An equation is an expression that shows the relationship between two or more variables and numbers.

Let x represent the number of hamburger sold and y represent the number of cheeseburgers sold, hence:

x + y = 460    (1)

Also:

y = 3x       (2)

From both equations:

x = 115, y = 345

Help!! Find the area of the triangle.

Answers

Answer:

Area = 60.0 units²

Step-by-step explanation:

First, let's find the height of the triangle using Pythagorean Theorem:

Height = √(11² - 8²)

= √57

Height = 7.5 (nearest tenth)

✔️Find the area:

Area = ½*base*height

Base = 2*8 = 16

Height = 7.5

Plug in the values

Area = ½*16*7.5

Area = 60.0 units² (nearest tenth)

Answer:

D. no solution

Step-by-step explanation:

substitute y = 2x + 3 in

During a test period, an experimental group of 10 vehicles using an 85 percent ethanol-gasoline mixture showed mean CO2 emissions of 240 pounds per 100 miles, with a standard deviation of 20 pounds. A control group of 14 vehicles using regular gasoline showed mean CO2 emissions of 252 pounds per 100 miles with a standard deviation of 15 pounds. A quick comparison of the sample variances suggests that the population variances are:

a. probably equal.
b. probably unequal.
c. incomparable.

Answers

Answer:

Probably unequal  ( B )

Step-by-step explanation:

experimental group = 10

using 85% ethanol gasoline

mean = 240 pounds per 100 miles

standard deviation = 20 pounds

control group = 14 vehicles

using regular gasoline

mean = 252 pounds per 100 miles

standard deviation = 15 pounds

comparing  the sample variance of each group shows that they are probably unequal using the equation below

Variance for a sample set of data = ∑ ( x - X ) ^2 / n - 1

where n = number of events

X = mean value

x = value of events

The remaining piece measures 16 m

which agrees with answer D

Step-by-step explanation:

In order to make a square of area 25 m^2, we need a square of side 5 m ,

Area of square = side^2

25 = side^2   then each side = 5 m

therefore the person needed 4 times 5 m  to create the square, that is 20 m for the square. Therefore the piece that is left can be calculated with the difference:

36 m - 20 m = 16 m

The remaining piece measures 16 m
