what is the chancr of rolling a 7 or a 9 on two dice .
Answer:
5/18 0r 27.77%
Step-by-step explanation:
I am assuming both are six-sided and have numbers 1-6 on each of the six sides. There are 36 possible roll combinations. Of the 36, four result in 9 and six result in 7. Therefore there is a 10/36 chance of rolling a 7 or a 9. That can be simplified however by dividing by two on both numbers. That equals 5/18. As a percent you would divide 5 by 18 and get 0.2777. After that you multiply 0.2777 by 100 to get 27.77%.

Answer:
$5.01 moneyyyyyy lollll
Answer:
$5.11
Step-by-step explanation:
what should be subtracted from (1/2+1/3+1/4) to get -2
1/2 + 1/3 + 1/4 - x = - 2
6/12 + 4/12 + 3/12 - x = - 2
6 + 4 + 3 / 12 - x = - 2
13/12 - x = - 2
x = 13/12 + 2
x = 13/12 + 24/12
x = 37/12 Or x = 3 1/12
Answer:
x = 37/12 Or x = 3 1/12
Step-by-step explanation:
1/2 + 1/3 + 1/4 - x = - 2
6/12 + 4/12 + 3/12 - x = - 2
6 + 4 + 3 / 12 - x = - 2
13/12 - x = - 2
x = 13/12 + 2
x = 13/12 + 24/12
x = 37/12 Or x = 3 1/12

zuma took a loan of 630 000 from the bank. he will repay the loan over 48 months at 9.5% per annum simple interest. how much interest will zuma pay on the loan
Answer:
Interest amount = 239400
Step-by-step explanation:
Below is the calculation of interest amount:
Given the loan amount or present value = 630000
Time period = 48 months or 4 years
Interest rate give = 9.5%
Total amount = P ( 1 + rt)
P = 630000
r = 9.5%
t = 4 years
Total amount = 630000 ( 1 + 9.5% x 4)
Total amount = 869,400
Interest amount = 869400 - 630000
Interest amount = 239400

(x - 5)² + 7y, if x = 144 and y = 16
Answer:
19433
Step-by-step explanation:
Substitute x = 144 and y = 16 into the expression
(144 - 5)² + 7(16)
= 139² + 112
= 19321 + 112
= 19433

A square garden has an area of 400 square feet. Each side of the garden is (x-10) feet in length.
Write an equation that represents the AREA of the garden
Find the value of x using the square root method
What is the length of the side of the garden?
Answer:
400 = (x - 10)²
x² -20x -300 = 0
x = 30 and x = -10
Length side of the garden = 20 feet
Step-by-step explanation:
Given:
Area of square garden = 400 square feet
Length side of the garden = (x - 10) feet
Find:
Length side of the garden
Computation:
Area of square = side²
Area of square garden = Length side of the garden²
400 = (x - 10)²
400 = x² -20x + 100
x² -20x -300 = 0
x² -30x + 10x -300 = 0
x(x - 30) + 10(x - 30) = 0
(x - 30)(x + 10) = 0
So,
x = 30 and x = -10
Use x = 30 positive number
Length side of the garden = (x - 10) feet
Length side of the garden = (30 - 10) feet
Length side of the garden = 20 feet
Ethan and Sam work at different department stores. Ethan is paid 125$ per week and an 8% commission on sales, while Sam is paid 200$ per week and a 6% commission on sales. Enter the amount in dollars of sales for which they earn the same weekly income
Answer:
3750$
Step-by-step explanation:
Let x be the amount in dollars of sales:
125 + 0.08x = 200 + 0.06x (when Ethan and Sam earn the same weekly income)
0.02x = 75
x = 3750

diameter of 9 feet. What is the
volume of the sphere?
Answer:
382 ft³ (3 s.f.)
Step-by-step explanation:
[tex]\boxed{volume \: of \: sphere = \frac{4}{ 3}\pi {r}^{3} }[/tex]
Radius= diameter ÷2
Rdaius of sphere
= 9 ÷2
= 4.5 ft
Volume of sphere
[tex] = \frac{4}{3} (\pi)(4.5)^{3} [/tex]

Answer:
Surface area of cubic box = 376 square inch
Step-by-step explanation:
Given:
Using net diagram
Length of cubic box = 10 inches
Width of cubic box = 6 inches
Height of cubic box = 8 inches
Find:
Surface area of cubic box
Computation:
Surface area of cuboid = 2[(lb) + (bh) + (hl)]
Surface area of cubic box = 2[(10)(6) + (6)(8) + (8)(10)]
Surface area of cubic box = 2[60 + 48 + 80]
Surface area of cubic box = 2[188]
Surface area of cubic box = 376 square inch
Which property of polynomial addition says that the sum of two polynomials is always a polynomial
Write the equation of the line, in slope-intercept form y=mx+b, that has a slope of 9 and a y-intercept of -3.
Step-by-step explanation:
We are supposed to write the equation in slope intercept form of a line . Firstly we know the slope intercept form as ,
[tex]\implies\sf y = mx + c [/tex]
Where ,
m is the slope c is the y Intercept .Now by question , the given data is ,
m = 9 c = -3On substituting the respective values we have ,
[tex]\sf\implies y = 3 * x + (-3)\\\\\sf\implies\red{ y = 3x - 3 } [/tex]
Hence the slope intercept form is y = 3x - 3 .

Answer:
Yes...your right...but no...its 28 degrees.
Step-by-step explanation:
So bascially, angle C is 90 degrees. So is angle D.
We know A is 28 degrees.
We know a tiangle is 180 degrees.
We dont know the degree of C in the first trinagle or the secodn triangle, but again, we know the total degrees of C is 90.
To find the missing angle, we must find what C is first.
So, we know we can subtract 90 from 180 to get 90. Since there is a 90 degree angle in the first triangle.
Next we can subtract 28, since we know that is the measure of angle A.
This gets us 62.
Now subtract 62 from the 90 degrees of angle C. THis will find us its angle in the second traingle.
This gets us 28.
This is our missing number.
So you were wrong in the sense that you solved for the wrong angle y, but you did get the right answer:
Since we know that a triangle is 180, and one of these is a right angle, there is 90 degrees.
If we subtracrt the 28 we got just now, we would get 62, which is angle B, or DBC.
However, the 28 is angle C, or DCB.
So your answer is actually 28, not 62.
Hope this helps!
Melissa wants to expand her rectangular sandbox that measures 4 feet by 8 feet. Two sides of the sandbox are against a fence. She wants to increase the length and the width of the sandbox by the same amount on the two sides that are not against the fence. The total area of the new sandbox will be 60 square feet. What is the amount of increase?
Answer:
The amount with which she should increase the length and the with of the sandbox is 2 feet each
Step-by-step explanation:
The dimensions of Melissa's rectangular box are;
Width of the box = 4 feet
Length of the box = 8 feet
The total area of the new sandbox, A = 60 square feet
Let 'x' represent the amount by which she increases the width and lengths of sides that not against the fence, we have;
The area of the new sandbox, A = The new length × The new width
A = 60 ft.²
The new length = 8 + x
The new width = 4 + x
∴ A = 60 = (8 + x) × (4 + x) = x² + 12·x + 32
60 = x² + 12·x + 32
60 - 60 = 0 = x² + 12·x + 32 - 60
∴ x² + 12·x - 28 = 0
(x + 14)·(x - 2) = 0
x = -14 or x = 2
Therefore, the amount she can increase the width and lengths of sides that not against the fence to have make a new sandbox with an area of 60 ft.² is, x = 2 feet
The amount of increase of the length and the width of the sandbox, x = 2 feet each.

Shawn wants to buy a bowling ball that typically costs $120. Currently, the bowling ball is on sale for 13% off. As a member of the bowling league, Shawn is also entitled to an additional 15% discount off the sale price of the bowling ball. If the sales tax in Shawn's state is 7.5%, what is the final price that Shawn will have to pay for the bowling ball?
Answer:
95.40
Step-by-step explanation:
120x.13=15.60. discount
120-15.60=104.40 sales price
104.40x.15=15.66 additional discount
104.40-15.66=88.74 additional sales price
88.74x.075=6.66 sales tax
88.74+6.66=95.40 total price

Find measure angle GJK (5x + 8) (7x - 16)
Hi there!
[tex]\large\boxed{22^o}[/tex]
Find m∠GJK by finding the value of its complementary angle and subtracting from 90°.
Using the Alternate Interior Angle theorem:
m∠HJI = m∠JHG, so:
7x - 16 = 5x + 8
Solve for x:
2x - 16 = 8
2x = 24
x = 12
Substitute in this value of x to solve for m∠HJI:
7(12) - 16 = 84 - 16 = 68°
Thus:
m∠GJH = 90 - 68° = 22°
Suki rode her bike 6/7 mile. Claire rode her bike 1/3 mile. They want to compare how far they each rode their bikes using benchmark 1/2. Select the correct answer to describe how to solve the problem.
Answer:
6/7 > 1/2
1/3 < 1/2
Suki rode her bike a longer distance than Clarie
Step-by-step explanation:
Suki's distance = 6/7 miles
Compare with bechmark 1/2
6/7 and 1/2
Make the denominators same
(6*2)/(7*2) and (1*7)/(2*7)
12/14 and 7/14
12/14 is greater than 7/14
12/14 > 7/14
Therefore, 6/7 > 1/2
Clarie distance = 1/3 miles
Compare with bechmark 1/2
1/3 and 1/2
Make the denominators same
(1*2)/(3*2) and (1*3)/(2*3)
2/6 and 3/6
2/6 is less than 3/6
2/6 < 3/6
Therefore,
1/3 < 1/2
Compare Suki's distance with Clarie
compare 6/7 and 1/3
Make the denominators same
(6 * 3)/(7 * 3) and (1 * 7)/(3 * 7)
18/21 and 7/21
18/21 > 7/21
Suki rode her bike a longer distance than Clarie
