Jill and Tim have the same number of toy cars. Tim has 10 red cars and 20 blue cars. Jill has 8 red cars, 15 blue cars, and some yellow cars. How many yellow cars does Jill have?
Answer:
7 yellow cars
Step-by-step explanation:
Tim has 30 cars, so Jill has 30 as well. She has 8+15=23 red and blue cars. This means that there are 7 yellow cars.
Use the formula Sn =a (1 - rn ) ÷ (1 – r) to find the sum Sn for each of the infinite and finite geometric series.
9. The first 9 terms of 12, – 6 ,+ 3, - …
10. The first 15 terms of -1, + 1, -…
11. The first 6 terms of 1, + 3, + …
12. The first 10 terms of 2, – 4, + …
Answer: 11
Step-by-step explanation:
9. The Sum of 9 terms is 513/64.
10. The sum of 15 terms is -1.
11. The sum of 6 terms is 364
12. The sum of 10 terms is -682.
We have,
Sn =a (1 - [tex]r^n[/tex] ) ÷ (1 – r)
9. 12, -6, 3, .....
Here, r= -6/ 12= -1/2
So, S(9)
= 12 (1- [tex](-1/2)^9[/tex])/ (1 - (-1/2))
= 513/ 64
10.-1, +1, -.....
Here, r= 1/ (-1)= -1
So, S(15) = 1 (1- [tex](-1)^{15[/tex])/ (1 - (-1))
= -1
11. 1, 3, .....
Here, r = 3/1 = 3
So, S(6) = 1 (1- [tex](3)^{6[/tex])/ (1 - 3)
= 364
12. 2, -4, ...
Here, r= (-4)/ 2= -2
So, S(10) = -682

Debra spends 42 minutes each day driving to work. About how many minutes does she spend driving to work each month?
Answer:
given,
time spent each day for driving to work = 42 mins time spent for driving work each month ( m ) = ?
we know ,
1 month is equal to 12 days
so,
m = 42× 12
= 504
hence, Debra spends 504 minutes driving each month.
10. If 0 = tan-'1, find angle 0. Angle 0 is an acute angle.
Answer:
45°
Step-by-step explanation:
θ = arctan(1) = 45°
__
Make sure your calculator is in degrees mode.

Additional comment
The tan⁻¹( ) function is the inverse tangent function. It can be read as "arctangent of ..." or "the angle whose tangent is ...". In spreadsheets and some calculators, it comes in two flavors: ATAN(x) and ATAN2(x, y). The latter is useful for finding the angle associated with a vector whose components are known, and that can be in any of the four quadrants.
Calculators will give an angle in degrees or radians according to the mode that is set. Spreadsheets always give the angle in radians. The range of a calculator tan⁻¹( ) or ATAN( ) function is -π/2 to π/2 radians, or -90° to 90°.

A line passes through the point (-2,-6) and has a slope of 5/2. Write an equation in slope-intercept from this line.
Slope = 5/2
y intercept = -1
======================================================
Work Shown:
m = 5/2 = slope
(x1,y1) = (-2,-6) = point the line goes through
y-y1 = m(x-x1) .... point slope form
y-(-6) = (5/2)(x-(-2))
y+6 = (5/2)(x+2)
y+6 = (5/2)x + (5/2)*2
y+6 = (5/2)x + 5
y = (5/2)x + 5 - 6
y = (5/2)x - 1
This equation is in slope intercept form y = mx+b
m = 5/2 = slope
b = -1 = y intercept

Find the value of sin D rounded to the nearest hundredth, if necessary.
Answer:
0.22
Step-by-step explanation:
So in this problem, we have to find the hypotenuse first, since sine is opposite over hypotenuse.
We can do this using the pythagorean theorem (you can search it if you don't know). Or, we can just remember this as one of our pythagorean triplets (9,40,41). The last side will be 41.
We have to find the value of sin(D)
opposite/hypotenuse = 9/41 = 0.2195 which is about 0.22

of 19 inches. What is the
area of the table?
Answer:
90.25π
Step-by-step explanation:
The formula for solving the area of a circle is πr².
r is the radius. We can find the radius by splitting the diameter in half: 19/2 = 9.5.
We can apply the area formula and we get π9.5² and the answer is 90.25π.

In a decorative figurine shop, it takes of an hour to paint 8
identical ceramic figurines. How long does it take to paint one
figurine? At the same rate, how long would it take to paint 12
figurines?
The time it would take to paint one figurine is 0.125 hour.
The time it would take to paint 8 figurine is 1.5 hours.
The first step is to determine the average rate. Average rate is the total ceramic figurines painted divided by the total time.
Average rate = 8 /1 = 8 figurines / hour
In order to determine how long it would take to paint 8 figurines, divide 12 by the average rate.
1 / 8 = 0.125 hour
In order to determine how long it would take to paint 8 figurines, divide 12 by the average rate.
12 / 8 = 1.5 hours

The Hu family goes out for lunch, and the price of the meal is $52. The sales tax on the meal is 6%, and the family also leaves a 20% tip on the pre-tax amount. What is the total cost of the meal?
Answer:
$65.52
Step-by-step explanation:
52 x 6% = 3.12. Multiply the price of the meal by the percentage of sales tax
52 x 20% = 10.4. Multiply the price of the meal by tip percent
$3.12 is the sales tax on the meal
$10.40 is the tip amount
$52 + $3.12 + $10.40 = $65.52
Add sales tax and the tip amount to the price of the meal to find the total
