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.

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.

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.

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.

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]

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

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.

Inequality

Step-by-step explanation:

I will take long to answer this so i will give you the key to answering it.

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

Hope this helps.

Answer:

lesser x = - 1 , greater x = 1

Step-by-step explanation:

- 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

then

lesser x = - 1

greater x = 1

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

Using it's concept, it is found that the absolute deviation of 30 in the data set is of 2.

The absolute deviation of a measure is given by the absolute value of the differente between the measure and the mean.

The mean is the sum of all observations divided by the number of observations. In this data-set, it is given by:

M = (26 + 35 + 27 + 30 + 22)/5 = 28

30 - 28 = 2, hence, the absolute deviation of 30 in the data set is of 2.

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
