Jose is in 8th grade, and he is researching his favorite colleges. He notices that the current cost of tuition, books and fees at one 4-year college is $14,500 per year.
What will be the total cost of tuition, books, and fees for Jose if he eventually chooses to attend this college for four years?
Here, we are given the cost of Jose for 1 year for attending college i.e $14500/year, and we need to find the total cost for Jose to attend college for 4 years, so here we can just use unitary method, we can just multiply the whole cost for 1 year by 4, to get the total cost for 4 years, as :
[tex]{:\implies \quad \sf Cost\:\: for\:\: 1\:\: year= \$14500}[/tex]
Now, multiplying by 4 on both sides will yield :
[tex]{:\implies \quad \sf Cost\:\: for\:\: 4\:\: years= \$14500\times 4}[/tex]
[tex]{:\implies \quad \boxed{\bf{Cost\:\: for\:\: 4\:\: years= \$58000}}}[/tex]
This is the required answer
The total cost of tuition, books, and fees for Jose if he eventually chooses to attend this college for four years is $58,000.
Total cost of tuitionUsing this formula
Total cost of tuition=Cost of tuition books and fees×Number of years
Where:
Cost of tuition books and fees=$14,500 per year
Number of years=4 years
Let plug in the formula
Total cost of tuition=$14,500 per year x 4 year
Total cost of tuition=$58,000
Inconclusion the total cost of tuition, books, and fees for Jose if he eventually chooses to attend this college for four years is $58,000.

What is mZRST in degrees? O 78° O 84° O 120° O 156°
Answer:
rst = ust + usr
6x+12 = 78 + 3x - 12
3x = 54
3x+66 = 54 + 66
3x +66= 120
thus rst = 120
The measure of angle ∠RST in degree is 156°
What is measure of an angle?The measure of angle is the amount of rotation performed by initial side to get the terminal side. A complete angle is divided by 360 equal parts we get 360 number of small angles. Each of these small angle has measure 1 degree.
Given that, ∠RSU=78° , ∠UST=(3x - 11)° and ∠RST=(6x + 12)°
Now, ∠RSU+UST=∠RST
Putting the values of ∠RST and ∠UST we get,
78 + (3x - 12) = 6x + 12
78 + 3x - 12 - 6x - 12 = 0
54 - 3x = 0
3x = 54
So, x = 54/3=18
Therefore, (6x + 12)°=(6×18 + 12)°
=(144 + 12)°
=156°
Hence the measure of angle ∠RST is 156°

A cylindrical can has an 8-cm radius and a height of 11 cm. Find its surface area.
Answer:
955.168 cm²
Step-by-step explanation:
The formula to find the surface area of a cylinder is :
Surface area = 2 π r ( r + h )
Here,
r ⇒ radius ⇒ 8 cm
h ⇒ height ⇒ 11 cm
So, Let us solve now.
Surface area = 2 π r ( r + h )
Surface area = 2 × 3.142 × 8 ( 8 + 11 )
Surface area = 50.272 × 19
Surface area = 955.168 cm²

6 9 12 15:- multiplying by 3.
Answer:
B) 9
Step-by-step explanation:
When looking in both the horizontal and vertical direction of the missing space, we can see that the difference between the two numbers, 12 and 15, is 3.
15 - 12 = 3
Using this, we can see that each space on the second row and second column change by 3. Therefore, when looking at the missing space in the sequence, we can figure out that it is 9 by adding 3 to 6.

feet. Unit cubes with side lengths of 1/2 foot are added to completely fill the prism with no space remaining. What is the volume, in cubic feet, of the right rectangular prism?
Answer: 11.25 ft³
Step-by-step explanation:
We can use the volume formula to solve. I will turn the halves into 0.5 for calculation purposes.
V = L * W * H
V = 2.5 * 3 * 1.5
V = 11.25 ft³
The volume of the rectangular prism is 11.25 ft³.

A rectangular banquet room has an area of 182 square meters and a perimeter of 54 meters. Let l and w represent the dimensions of the room in meters. Which statements describe the dimensions of the banquet room? Select all that apply.
Answer:
Choose all but C
Step-by-step explanation:
Givens
Area = 182 m^2
Perimeter = 54 m
Solution.
B: solves for the length, not the width. Area = L*w. Area / w = L. But to get to the length, you need to solve for the width. So this statement can be used. B is true.
C is not true. The length and width differ by 1 which means one of them is even and the other is odd. See below under A.
D is also true. 2L = 54 - 2w Divide both sides by 2
2L/2 = 54/2 - 2w/2
L = 27 - w
E is true.
L * w = 182 Divide both sides by w
L = 182/w
The only one we don't know about is A. We have to solve the problem to get the answer to A.
P= 2L + 2w = 54
2L + 2w = 54
L + w = 27
L = 27 - w
L*w = 182
(27 - w ) * w = 182 Remove the brackets
27w - w^2 = 182 Subtract 27w - w^2 from both sides.
0 = w^2 - 27w + 182 Notice the sign change. Subtraction does that.
This factors into
(w - 13)(w - 14)
A turns out to be true, because w can be 13 or 14. When W = 13, L = 14.
When w = 14, L = 13

rachel bought an equal number of bowls and plates for$96. each plate cost $2 and each bowl cost $4 more than each plate. how much did she spend on all the plates
Answer:
$24
Step-by-step explanation:
Cost per plate: $2
Cost per Bowl: $2 + $4 = $6
Cost of 1 Plate and 1 Bowl: $2 + $6 = $8
Total cost of $96 divided by Cost of 1 Plate and 1 Bowl $8 = 12 sets of 1 Plate and 1 Bowl
12 plates x $2 Cost per Plate = $24
Answer:
$24
Step-by-step explanation:
Let [tex]b[/tex] = bowl
Let [tex]p[/tex] = plate
Given:
Equal number of bowls and plates for $961 plate = $2 1 bowl = $4 + $2 = $61) We can translate these into algebra. Since Rachel has equal number of bowls and plates, [tex]b=p[/tex], totaling to $96.
[tex]b=p\\2p + 6b = 96[/tex]
2) We can solve for [tex]p[/tex] these two equations simultaneously using the substitution ot elimination method. I will demonstrate using the substitution method here.
[tex]2p + 6(p) = 96\\2p+ 6p = 96\\8p = 96\\p = \frac{96}{8} \\p = 12[/tex]
So, Rachel bought 12 plates and 12 bowls since plates are equivalent to bowls.
3) Use ratio to find the the cost of the plates.
[tex]1p[/tex] = $2
[tex]12p[/tex] = $24
Dana just finished paying off the $15,400 loan she took out four years ago. the loan had 6.68% interest, compounded monthly. if dana paid a total of $18,321.60, how much did she pay in service charges? a. $730.08 b. $366.49 c. $1,028.72 d. $266.76 please select the best answer from the choices provided a b c d
If Dana paid a total of $18,321.60, then the amount that she paid for in service charges will be $730.08
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
For service charge
[tex]\rm Pv = PMT[(1 - (1 + (r/k))^{-kn}) / (r/k)][/tex]
Where;
Pv is the amount of the loan = $15400
PMT is monthly payment
R is interest rate = 6.68% = 0.0668
K is number of times compounded monthly = 12
N is time = 4years
PMT the subject of the formula gives
[tex]PMT = Pv/ [(1 - (1 + (r/k))^{-kn}) /(r/k)][/tex]
PMT = 15,400 ÷ ((1 − (1 + 0.0668 ÷ 12)^(−12 × 4)) ÷ (0.0668 ÷ 12))
PMT = 366.49
Thus, the total amount paid
A = 366.49 × 12months × 4years
A = $17,591.52
Thus, the Service charge is
S.C = 18,321.60 − 17,591.52
S.C = $730.08

if two dice are thrown together , what is the probability of getting an even number on one die and odd number on the other die ?
Answer:
1/2
Step-by-step explanation:
the probability of the die rolling an even number = the probability of the die rolling an odd number =1/2
Let us name these 2 dice as A and B
One die can roll an even and the other can roll an odd, in the following cases
A rolls even and B rolls odd. The probability of this happening =1/2×1/2
A rolls odd and B rolls even. The probability of this happening =1/2×1/2
∴ The required probability
=1/2×1/2+1/2×1/2
=1/4+1/4
