3x - 4y = 13
-2x + 3y = -10

what is the solution?

Answer:

a.0.045km

d.4500cm

e.45000mm

Step-by-step explanation:

45meters is equivalent to 0.045km,4500cm,45000mm

Therefore the right answers are

a.0.045km

d.4500cm

e.45000mm

To determine which measurements are equivalent to 45 meters, we need to convert the given options to meters and compare them to 45 meters is 0.045 kilometers Therefore the correct option is A,B,D,E.

a. 0.045 kilometers: To convert kilometers to meters, we multiply by 1000. So, 0.045 kilometers is equal to 0.045 x 1000 = 45 meters. b. 0.45 kilometers: Similarly, 0.45 kilometers is equal to 0.45 x 1000 = 450 meters. c. 450 centimeters: To convert centimeters to meters, we divide by 100. So, 450 centimeters is equal to 450 / 100 = 4.5 meters.

d. 4,500 centimeters: Again, 4,500 centimeters is equal to 4,500 / 100 = 45 meters. e. 45,000 millimeters: To converted millimeters to meters, we divide by 1000. So, 45,000 millimeters is equal to 45,000 / 1000 = 45 meters.

Therefore, the measurements that are equivalent to 45 meters are a. 0.045 kilometers, b. 0.45 kilometers, d. 4,500 centimeters, and e. 45,000 millimeters. These measurements all represent the same length as 45 meters.

Hence the correct option is A,B,D,E.

Understandable. Have a good day.

thats so cool btw thanks for the free points have a great day !

150.7

To solve this, we first turn both the fractions into decimals :

[tex]\frac{1}{5} = 0.2\\[/tex]    (add this to 426 to get 426.2)

[tex]\frac{1}{2} = 0.5[/tex]    (add this to 275 to get 275.5)

Then, just solve the equation :

426.2 - 275.5 = 150.7

Step-by-step explanation:

Volume cone formula: V=πr^2h/3

V = π(6)^2 3/3

V = 113.1

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Answer:

113.04 cubic inches

Step-by-step explanation:

First lets identify the equation to find the volume of a cone.

V= [tex]\pi[/tex] r^2 h/3

Next we'll plug in height and radius

h = 3

r = 6

V = [tex]\pi[/tex] 6^2 * 3/3

V = [tex]\pi[/tex] 36 * 3/3

V = [tex]\pi[/tex] 36 * 1

V = [tex]\pi[/tex] 36

V = 36[tex]\pi[/tex]

Now we'll use 3.14 for [tex]\pi[/tex] and times it by the 36

V = 36[tex]\pi[/tex]

V = 113.04

V= 113.04 cubic inches

Answer:

[tex]a=7.5[/tex]

Step-by-step explanation:

Given the function [tex]f(x)=6x-15[/tex] and the output [tex]30[/tex] when [tex]x=a[/tex], we can write the equation:

[tex]6a-15=30[/tex]

[tex]6a=45[/tex]

[tex]a=7.5[/tex]

We can insert the value of [tex]a[/tex] into the function to verify the output equals [tex]30[/tex]:

[tex]f(a) = 6a-15[/tex]

[tex]= 6(7.5)-15[/tex]

[tex]=30[/tex]

∴ We have verified that [tex]a=7.5[/tex]

Step-by-step explanation:

Answer:

28.125 hours

Step-by-step explanation:

Amount of money paid per hour = $8

Bonus of being a manager = $25

Total amount of money paid = $250

To find:

Number of hours worked for this month?

Solution:

Let the number of hours worked = [tex]h[/tex] hours

Amount of money paid for [tex]h[/tex] hours = $8[tex]h[/tex]

As per question statement:

Bonus + Amount of money paid for [tex]h[/tex] hours = $250

[tex]25 + 8h = 250\\\Rightarrow 8h = 250 -25\\\Rightarrow 8h = 225\\\Rightarrow h =\dfrac{225}{8}\\\Rightarrow \bold{h = 28.125\ hours}[/tex]

Therefore, the answer is:

Number of hours worked = 28.125 hours

the metal bar/random line is almost the same size as the other two sides of the triangle. if one side is 32ft, then the opposite side is 32ft also. the bottom is 100ft, so we could eliminate C. because it couldnt be that number. now the bottom triangle, one side is 40ft so the other side has to be 40ft as well. its asking about the metal bar.

its either:

A. 53.2ft     or

B. 44.4

because the line is almost the same size as 32ft. its almost a equallateral triangle. i would go with A. though because if you imagine the line at the bottom of the line (100ft.) the line would go over half of it (and 53.2 is over half of 100) so i would say

A.53.2

if this didnt help let me know. and i will delete this (if i can-)
