The cost of parts on your automobile repair bill was $149. The cost for labor was $25Per hour. Write a linear equation giving the total cost C, in terms of t, the number of
Hours. C(t)

Answers

Answer 1

Answer:

Answer:

C=149+25t

Step-by-step explanation:

Since the total cost is C you would set it all equal to C.

Then the one time cost for parts was 149 so you have to add that in.

And $25 per hour would be multiplied by t because t is the number of hours.

The names of 9 boys and 2 girls in a hat. What is the probability of first drawing a girls name then a boys name from the hat?

Answers

A - drawing a girls name at first
P(A) = 2/(2+9) = 2/11
B - drawing a boys name in second drawing if first drawing was a girls name
P(B) = 9/10
C - drawing a girls name firstly and a boys name secondly
P(C) = P(A) * P(B) = 2/11 * 9/10 = 9/55
ans: 9/55

The sum of 3 consecutive odd integers is 87.Find the equation used to solve this problem and the three integers.

Answers

the first odd integer is x. The next odd integer will be x+2. and the next is x+4. Then we can say that (x)+(x+2)+(x+4)=87
working that out yields 3x+6=87
and thus 3x=81
and by consequence x=27

and thus our 3 odd integers are 27,29 and 31

Let be y - 2, y and y + 2 the 3 consecutives odd integers;
There sum is 3y, and, in the same time is 87 => y = 87/3 => y = 29 =>
y - 2 = 27; y + 2 = 31;
The 3 integers are : 27, 29, 31.

Explain why it is necessary to rename 4 1/4 if you subtract 3/4 from it

Answers

To rename mixed numbers it need to be keep in mind that the equal forms of the fraction or the whole number. The given mixed number is renamed as three and half after the subtraction, because the value of the mixed number is changed after the subtraction.

Given information-

Mixed number given in the problem is,

$4(1)/(4)$

This mixed number can be named as four and one fourth.

What is mixed number?

Mixed numbers are the combination of the whole number and the fraction number. When the whole number and the part of the whole number is written combined, it is called the mixed number.

Subtracting mixed numbers by renaming-

To rename mixed numbers it need to be keep in mind that the equal forms of the fraction or the whole number.

Now to subtract the given mixed number from the given fraction number change it in the form of fraction form,

$4(1)/(4) -(3)/(4) =(17)/(4) -(3)/(4)\n$

Subtract as the denominator is same,

$4(1)/(4) -(3)/(4) =(17-3)/(4)\n4(1)/(4) -(3)/(4) =(14)/(4)$

The result 14/4 can be renamed in the mixed form as,

$(14)/(4)=3(1)/(2)$

Hence the given mixed number is renamed as three and half after the subtraction, because the value of the mixed number is changed after the subtraction.

You would rename four and one fourth when subtracted from three fourths because when you subtract the fractions you get a different fraction for your answer.
$4 (1)/(4)- (3)/(4)= 3 (1)/(2)$
so you would said three and one half instead of four and one fourth.

What is the area of the composite figure?

Answers

To find the area of the triangle, you do 1/2*4*9 which is 18 (you do four because 10-6 is four)
For the rectangle, 9*6 which is 54
Then you plus 54 and 18 together which is 72:)
