Answer:

It would be 63

x=63

Step-by-step explanation:

Because 63*1/9=7 and then 17-7=10

Since 10=10, the value of x we have solved for is correct.

Please mark me brainliest, I worked hard.

You must give an estimate to service an automobile. The hourly rate for labor is $7.50. You estimate the job will take 2 1/2 hou

LUCKY_DIMON [66]

Answer:
job estimate = $60.1875

Explanation:
1- labor payment:
The hourly rate is $7.5 and the job will take around 2.5 hours. This means that:
labor payment = 7.2 * 2.5 = $18.75

2- Overhead value:
The overhead value is 85%.
This means that:
its cost would be = 85% * labor payment
= 0.85 * 18.75
= $15.9375

3- Retail cost:
We are given that the retail cost is $25.5

4- getting the job estimate:
job estimate = labor payment + overhead cost + retail
job estimate = 18.75 + 15.9375 + 25.5
job estimate = $60.1875

Hope this helps :)

A college has space for 580 students. The college estimates that 65% of the students who are admitted will attend the college. H

marshall27 [118]

Answer:

The number of students whom should be admitted is 377.

Step-by-step explanation:

Given:

College has space for 580 students.

The college estimates that 65% of the students who are admitted will attend the college.

Now, to find the number of students whom should be admitted.

Space for total number of students = 580.

Percentage of the students who are admitted = 65%.

Total number of students whom should be admitted = 65% of 580.

$=\frac{65}{100}\times 580$

$=\frac{37700}{100}$

$=377.$

Therefore, the number of students whom should be admitted is 377.

$\\ \: \: \implies \: sin^{4} \: \theta + cos^{4} \: \theta \rightarrow \blue{ \frac{1}{2} }$

$\\ \bf \: Given :$

$\\ \sf \: \: \bf sin \: \theta - cos \: \theta = 0$

$\\ \sf \rightarrow \: sin \: \theta = cos \: \theta$

$\\ \sf \rightarrow \: \frac{sin \: \theta} {cos \: \theta} = 1$

$\\ \sf \rightarrow \: tan \: \theta = 1$

$\\ \sf \rightarrow \: tan \: \theta = tan \: 45 \degree$

$\\ \sf \rightarrow \: \theta = 45 \degree$

$\\ \\ \therefore \: sin^{4} \: \theta + cos^{4} \: \theta$

$\\ \sf \rightarrow \: sin^{4} \: 45 \degree + cos^{4} \: 45 \degree$
