Is this correct if not why !!!!!!!
====================================================
Explanation:
Use the cosine ratio to get the following,
cos(angle) = adjacent/hypotenuse
cos(71) = 20/x
x*cos(71) = 20
x = 20/cos(71)
x = 61.431 approximately
x = 61.4
Notes:
The hypotenuse is always the longest side of any right triangle, so x must be larger than 20.Make sure your calculator is in degree mode.Answer:
x ≈ 61.4
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{20}{x}[/tex] ( multiply both sides by x )
x × cos71° = 20 ( divide both sides by cos71° )
x = [tex]\frac{20}{cos71}[/tex] ≈ 61.4 ( to the nearest tenth )

Twenty-two more than three times a number is equal to the difference between 6464 and three times the number. Find the number.
Answer:
7
Step-by-step explanation:
a number: x
3 times a number: 3x
twenty-two more than 3 times a number: 3x + 22
difference between 64 and 3 times the number: 64 - 3x
3x + 22 = 64 - 3x
6x = 42
x = 7
Answer: 7
Vijay's family is leaving for Galactic Gardens Resort once his parents get home from work on Friday. Their house is 544 miles from the resort. They plan to stop and spend the night at a hotel after 3 hours of driving, then complete the rest of the trip on the second day. If their average speed is 64 miles per hour, how long will they drive on the second day?
Answer is not multiple choice!
Write your answer as a whole number or a decimal.
Answer:
5.5 hours i think
Step-by-step explanation:
64 x 3 = 192 for the first day
544 - 192 = 352
64 x 5.5 = 352
therefor your anwser is 5.5
The time taken by Vijay's family to drive on the second day is 5.5 hours.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
The time is calculated as:-
For 3 hours of driving at an average speed of 64 miles per hour, the distance covered is,
d = 64 x 3 = 192miles
Miles remaining for the second day is,
544 - 192 = 352 miles
Time taken to cover 352 miles second day is,
T = 352 / 64 = 5.5 hours

What is the solution to this equation? 7-1^3 √2-x=12
X=5
Answer:
x = 127
Step-by-step explanation:
[tex]7-\sqrt[3]{2-x} = 12[/tex] , add the cube root to both sides and subtract the 12
[tex]7-12 = \sqrt[3]{2-x}[/tex], combine like terms
[tex]-5 = \sqrt[3]{2-x}[/tex], raise both sides to the third power
[tex](-5)^{3} = (\sqrt[3]{2-x} )^{3}[/tex], simplify
[tex]-125= 2-x[/tex] , to isolate the variable subtract 2 from both sides
[tex]-125-2 =-x[/tex], combine like terms
[tex]-127=-x[/tex], multiply both sides by -1
[tex]127=x[/tex] Finished!

2. Avery is painting more tables. It takes 1/4 gallon of paitn to cover a table. IF she has a 5/6 gallon of paint, how many tables can she cover?
A) Write a division number sentence that relates to your model:
B) Write a multiplication number sentence to check your answer:
C) Show how many tables Avery paints:
Answer:
please see analysis
Step-by-step explanation:
You can do this with a proportion. It takes 5/6 of a gallon to paint 1 wall and you want to know how much of a wall can you paint with 1/2 gallon. So set up the proportion:
5/6 / 1 = 1/2 / x
cross multiplying gets you 5/6x = 1/2
multiply by the reciprocal of 5/6 to isolate x - which is 6/5. 1/2 times 6/5 = 3/5

What is the value of x in the triangle at the right?
Answer:
x=20
Step-by-step explanation:
To find x use the fact that all triangle's angles sum to 180. This means that if you add all of the angles together, they will always equal 180 degrees. So, create an equation to represent this.
The equation looks like this:2x+65+75=180
Then, combine the like terms2x+140=180
Next, subtract 140 from both sides2x=40
Finally, divide both sides by 2x=20
This means that the missing angle is 40 degrees.
