help please i need help
Answer:
XZ ≈ 14.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle, that is
cos29° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{YZ}{XZ}[/tex] = [tex]\frac{12.6}{XZ}[/tex] ( multiply both sides by XZ )
XZ × cos29° = 12.6 ( divide both sides by cos29° )
XZ = [tex]\frac{12.6}{cos29}[/tex] ≈ 14.4 cm ( to 3 significant figures )

Please help and explain so I understand!!
Answer:
x=5
Step-by-step explanation:
[tex]4x^2-11=89[/tex]
add 11 to both sides
[tex]4x^2=100[/tex]
Divide 4 on both sides
[tex]x^2=25[/tex]
Take the square root of both sides to eliminate the power of two from x
[tex]\sqrt{x^2} =\sqrt{25}[/tex]
Simplify
[tex]x=5[/tex]

Given that the following angles are supplementary. What is the measure of the missing angle?
Answer:
62 degrees
Step-by-step explanation:
Since it is a straightline, the sum of both angles are 180
So, 180 - 118 = 62
What is the product in lowest terms? 1/6 • 5/7
Multiply the numerator together and the denominators together.
1 x 5 / 6 . 7 = 5/42
42 is not a multiple of 5 so the answer is already in the lowest term.
The answer is 5/42

You want to rent a car for the day.Prestige car rentals charges $47 plus $0.07 per mile to rent a midsize vehicle . Gateway Auto changes a $35 fee plus $0.12 per mile for the same car. For what number of miles will both companies charge the same price?
Answer:
240 miles
Step-by-step explanation:
Given that:
Charges offered by Prestige car rentals for renting a midsize vehicle:
Fixed charges = $47
Per mile charges for renting a midsize vehicle = $0.07
Charges offered by Gateway Auto for renting a midsize vehicle:
Fixed charges = $35
Per mile charges for renting a midsize vehicle = $0.12
To find:
Number of miles for which both the companies charge the same price?
Solution:
Let the number of miles for which both the companies will charge the same price = [tex]x[/tex] miles
Charges for one mile by Prestige car rentals = $0.07
Charges for [tex]x[/tex] miles by Prestige car rentals = $0.07[tex]x[/tex]
Total charges by Prestige Car rentals = $47 + $0.07[tex]x[/tex]
Charges for one mile by Gateway Auto = $0.12
Charges for [tex]x[/tex] miles by Gateway Auto = $0.12[tex]x[/tex]
Total charges by Gateway Auto = $35 + $0.12[tex]x[/tex]
As per question statement, the charges are same:
[tex]\$47 + \$0.07x = \$35 + \$0.12x\\\Rightarrow 12=0.05x\\\Rightarrow x=\dfrac{1200}{5}\\\Rightarrow \bold{x=240\ miles}[/tex]

The graph of a linear relationship passes through (0, 3), and (3, 9). Which is an equation for this linear relationship?
Step-by-step explanation:
1. First calculate for the gradient m
2. Calculate for the constant C by using any point (0,3) or (3,9)
3. Lastly, put the values found in the equation y = mx + c
1. m = Y2-Y1/X2-X1
=9-3/3-0=2
2. input one point together with m into the equation y=mx+c
3=2(0)+C
C=3
3. Therefore equation of linear relationship is
y = 2x + 3
Laura earns $66 washing 6 cars. At this rate, how many cars did Laura wash to earn $88?
Answer:
8 car's for 88$ the same thing for the 6 car's for 66$
Answer:
Laura washed 8 cars to earn $ 88
Step-by-step explanation:
Number of cars : earnings = 6 : 66
6 : 66 :: x : 88
Product of mean = Product of extremes
66 * x = 6 *88
x = [tex]\frac{6*88}{66} = \frac{1*88}{11}[/tex]
x = 8

Given that 6x – 5y = 14
Find x when y = 2
Answer:
x = 4
Step-by-step explanation:
Given
6x - 5y = 14 ← substitute y = 2 into the equation
6x - 5(2) = 14
6x - 10 = 14 ( add 10 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4
Answer:
[tex]\huge\boxed{\sf x = 4}[/tex]
Step-by-step explanation:
[tex]\sf 6x-5y = 14\\\\Put \ y = 2\\\\6x - 5(2) = 14\\\\6x - 10 = 14\\\\ Adding \ 10 \ to \ both \ sides\\\\6x = 14+10\\\\6x = 24\\\\Dividing \ both \ sides \ by \ 6\\\\x = 24 / 6\\\\x = 4\\\\\rule[225]{225}{2}[/tex]

~AH1807For every 3 dozen cookies, a bakery uses 8 cups of butter. How many dozen of cookies could you make with 20 cups of butter?
Answer:
7 1/2 dozen of cookies
Step-by-step explanation:
If for every 3 dozen cookies, a bakery uses 8 cups of butter then we can say;
3 dozens cookies = 8 cups of butter
x cups of cookies = 20 cups of butter
Cross multiply
8*x = 3 * 20
8x = 60
x = 60/8
x = 7 4/8
x = 7 1/2
Hence you will need 7 1/2 dozen of cookies

Answer:
to find the total number of miles traveled, you have to add the total distance from point L to point M together. 929+ 595 = 1,524 total miles traveled
to find the average miles per hour, you divide the total miles traveled, by the amount of time it took. 1,524 / 3 = 508 miles per hour
Step-by-step explanation:
Answer:
Step-by-step explanation:
LV to Colorado Springs = 595 miles
Colorado Springs to Mil= 929 miles
Total distance = 1524 miles
Average Speed = 1524 miles / 3 hours
Average Speed = 508 miles / hour
