The first term of an arithmetic progression is 18 and the 18th is 60. Determine the common difference of the A.P
Answer:
42/17
Step-by-step explanation:
First term, a = 18
T18 = 60
Common difference, d = ?
[tex]T_{18} = 18 + (18 - 1)d \\ 60 = 18 + 17d \\ 17d = 42 \\ d = \frac{42}{17} [/tex]

“Four times the cube root of x, minus nine”
Answer:
D, because the word problem separates the minus nine with a comma.
a is incorrect because there is no cube root
b is incorrect because again, no cube root
c is incorrect because the minus nine should not be within the cube root
Four times the cube root of x, minus nine is [tex]4\sqrt[3]{x-9}[/tex].So, our correct answer is 3. [tex]4\sqrt[3]{x-9}[/tex] .Here are a few ways to write "Four times the cube root of x, minus nine":
4 * √(x) - 9
4√(x) - 9
[tex]4\sqrt[3]{x-9}[/tex]
The first way to write it is the most literal way. It uses the multiplication symbol (*) to indicate that we are multiplying 4 and √(x). The second way to write it is a bit more concise. It uses the exponent notation to indicate that we are taking the cube root of x. The third way to write it is the most mathematical way. It uses the LaTeX symbol for the square root, which is \sqrt{}.Which way you choose to write it depends on the context. If you are writing in a more informal setting, you might use the first way. If you are writing in a more formal setting, you might use the third way

Nathan and some friends are going to the movies. At the theater, they sell a bag of
popcorn for $4.50 and a drink for $4.25. How much would it cost if they bought 7
bags of popcorn and 3 drinks? How much would it cost if they bought p bags of
popcorn and d drinks?
Answer:
$44.25
Step-by-step explanation:
($4.50×7)+(4.25×3)
=$31.50+$12.75
=$44.25
$44.25 is the cost if they bought 7 bags of popcorn and 3 drinks and 4.50p+4.25d is for p bags of popcorn and d drinks.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that
popcorn for $4.50
drink for $4.25.
There are 7 bags of popcorn and 3 drinks.
So let us find the total cost.
7(4.50)+3(4.25)
31.5+12.75
44.25
So $44.25 is the cost if they bought 7 bags of popcorn and 3 drinks
Now we need to find cost for p bags of popcorn and d drinks.
4.50p+4.25d
Hence $44.25 is the cost if they bought 7 bags of popcorn and 3 drinks and 4.50p+4.25d is for p bags of popcorn and d drinks.

Kelly's mother is 35. Kelly is 13. How old will Kelly's mom be when Kelly is 50?
REAL CAREFULLY PLEASE HELP
[tex]Thank you![/tex]
________________________________________________________
If Kelly's mom is 35, it will take her 15 more years to become 50. Make an equation to represent this.[tex]35 + 15 = 50[/tex]
Next, you want to add 15 to Kelly's age because for each year her mom ages, she ages for that same number of years.[tex]13 + 15 = 28[/tex]
________________________________________________________
For the second problem, we just do an inverse of the problem. If Kelly is 13 and her mom is 35, how long will it take Kelly to become 50? How old will her mom be?It would take Kelly 37 more years to become 50, because 37 + 13 = 50
Now that we have found the number of years remaining, add her mother's age by the remaining years left, r

Answer:
n ≥ 7
Step-by-step explanation:
The English descriptor "is at least" corresponds to the math relation "is greater than or equal to." In symbols, we have ...
"n is at least 7" ⇔ n ≥ 7
Answer:
n ≥ 7
Step-by-step explanation:
If the question states "at least 7", it means the inequality should include 7 and the rest of the values lying in the set of the inequality are greater than 7 as 7 is the least value.

Solve for x. Round to the nearest tenth, if necessary.
Answer:
since the adjacent is given which is 6.3 and we are to solve for the hypotenuse, it's best to use Cos
since Cos(27°)=adjacent/hypotenuse
we can substitute in the values
therefore we have Cos(27°)=6.3/x
x=6.3/Cos(27°)
x=7.06...
rounding this to the nearest tenth will be 7.1
therefore x=7.1
Solve for x.

- 4x² - 7 = - 11 ( add 7 to both sides )
- 4x² = - 4 ( divide both sides by - 4 )
x² = 1 ( take square root of both sides )
x = ± [tex]\sqrt{1}[/tex] = ± 1

Basically, since you know the sum of all the angles of a triangle equal 180, all you have to do is use 180 and subtract the numbers alredy there together to get the missing amount.
For example, to find out the answer to A, you already know two of the degree measurements which are 72 and 68. Now, subtract them with 180.
72+68=140
180-140=40
So, therefore, A equals 40 degrees.
I will give you one more example.
If you want to find the measurements of the angles B and C, the same process will happen. The only thing that is different is that only one known measurement is provided which is 36.5 but not so fast, they gave you a hint. That square above B. That means B is a right angle. So we got one measurement in the triangle, B is 90 degrees. Alright now continue like before.
90+36.5=126.5
180-126.5=53.5

6. Roger bought a hamburger and french fries for $4.84. He paid with a $10 bill. Abouthow much change should he have gotten back? ESTIMATE UR ANSWER AND SHOW UR WORK PLS!
Answer:
The toys cost about $12.
Roger should have gotten back about $5.15 in change.
Step-by-step explanation:
Dog Toys Question:
Bone cost $5.25, so you can estimate it to be about $5.
Frisbee cost $6.75, so you can estimate it to be about &7.
To get estimated total, add $5 + $7 = about $12 total.
Roger's Change Question:
The hamburger and fries cost $4.84, so you can round that out to $4.85.
$10 - estimated $4.85 = about $5.15 in change.
You could also round the $4.84 cost of the hamburger and fries to $5 even. In this case, $10 - estimated $5 = about $5 in change.
4. Find the surface area of the triangular prism:
5 ft
5 ft
3 ft
14 ft
8 ft
Shows work please
Answer:
276ft^2
Step-by-step explanation:
A triangular prism is made up of multiple faces, just like any three-dimensional shape. Let's do the calculations for this shape together.
Top two faces: 5ft × 14ft × 2 = 140ft^2 (we multiply by two b/c there are two rectangles, so we save a step)
Front and back face: 8ft × 3ft = 24ft^2 (we do not divide by two b/c there are two triangles, so we save a step)
Bottom face*: 8ft × 14ft = 112ft^2
*Note: Don't solve for this face when calculating latent surface area, or when calculating the SA of a compound shape.
Now, we just add up the areas of all the shapes.
140 + 112 + 24 = 276
Final answer: 276ft^2
the radius r of a sphere is 4cm and is increasing at the rate of 0.5cm . At what rate is the volume?
Answer:
32π or 100.53 cm^3 to the nearest hundredth.
Step-by-step explanation:
dr/dt = 0.5
V = (4/3)π r^3
So dV/dr = (4/3)* 3 π r^(3-1)
= 4πr^2
Rate of increase in volume:
dV/dt = dV/dr * dr/dt
At r = 4:
Rate of increase in Volume
dV/dt = 4π(4)^2 * 0.5
= 64π * 0.5
= 32π.
