Answer:

V=14.14ft^3

Step-by-step explanation:

V=4/3(π)1.5^3

=4/3(π)3.375

=14.14ft^3

Answer:

14.1 ft³ (to 3 s.f.)

Step-by-step explanation:

[tex]\boxed{volume \: of \: sphere = \frac{4}{3}π{r}^{3} }[/tex]

Given that the radius is 1.5 feet, substitute r= 1.5 into the formula above:

Volume of sphere

[tex] = \frac{4}{3} (π)( {1.5}^{3} ) \\ = 14.1 \: ft^{3} [/tex]

(to 3 s.f.)

Answer:

[tex]\huge\boxed{a=\frac{bc}{d}}[/tex]

Step-by-step explanation:

In order to find the value of a when we have the equation [tex]bc=ad[/tex], our goal is to isolate a on one side.

The key question here is: what's stopping a from being alone on one side? That would be it being multiplied by [tex]d[/tex]. If we were able to remove the d, we would have a by itself.

Since we are multiplying a and d, we can get rid of the d by dividing both sides by d.

We have to divide both sides of the equation by the same value in order to keep it equal.

[tex]bc \div d = ad \div d\\\\\frac{bc}{d}=a\\\\a = \frac{bc}{d}[/tex]

Answer:

1 mile

Step-by-step explanation:

Answer:

Number line from negative 10 to positive 10 in increments of 1 is shown. Only the whole numbers are labeled. A point labeled R is placed between the 4th and 5th tick marks to the left of 0. A point labeled T is placed on the 3rd tick mark to the right of 0.

Step-by-step explanation:

The points given are (-4.5,0) and (3,0), which means the points are on the x-axis. Point R (-4.5,0) will be located to the left of 0, the negative side of the number line between the 4th and 5th marks. Point T (3,0) will be located to the right of 0, the positive side of the number line at the 3rd mark.

The second answer is incorrect because point (-4.5,0) is not on the right side of 0 but on the left side.

The third answer is incorrect because point T(3,0) is place between 2 and first mark instead of the third mark.

The fourth answer is incorrect because R (-4.5,0) is placed on the first mark instead of between 4th and 5th mark.

Answer:

Number line from negative 10 to positive 10 in increments of 1 is shown. Only the whole numbers are labeled. A point labeled R is placed between the 4th and 5th tick marks to the left of 0. A point labeled T is placed on the 3rd tick mark to the right of 0.

Answer:

Each pencil costs $1.25

Step-by-step explanation:

$18.74 - 4.99=13.75

13.75/11=$1.25

You have to take the total amount and subtract how much the paper pad costs then you get 13.75 and that is how much the student paid for all 11 pencils so you divide it by 11 and you get $1.25

Step-by-step explanation:

To find the common ratio ( r) of a given sequence , divide the previous term by the next term.

That's

[tex]r = - \frac{51}{17} = - 3 \: \: \\ or \\ r = - \frac{153}{51} = - 3[/tex]

Since the common ratio is the same for any of the terms chosen , the common ratio is - 3

Answer:

 =  − 4

Step-by-step explanation:

The value of the expression is 2419.

The required answer is 2400.5

Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube  roots, plus and minus.

Now the given expression is,

44[(9 + 3) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (3.5 - 2)) - 9]

It can be simplified using PEMDAS rule.

P is parenthesis

E is exponents

M is multiplication

D is division

A is addition

S is subtraction

Firstly we will solve parenthesis, thus

44[(9 + 3) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (3.5 - 2)) - 9]

= 44[(12) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (1.5)) - 9]

= 44[12 + 72 - 6 * 2.5 - 19] - [42 - 3(78.5) - 9]

Now we will solve multiplication,

= 44[12 + 72 - 15 - 19] - [42 - 235.5 - 9]

Now we will solve addition,

= 44[84 - 15 - 19] - [42 - 235.5 - 9]

Now we will solve subtraction,

= 44[84 -34] - [42 - 244.5]

= 44[50] - [42 - 244.5]

= 44[50] - [-200.5]

= 2200+  200.5

= 2400.5

Thus, the required answer is 2400.5

Answer:

Allocation: 4 samples should be from the mountain and 16 from along the coast.

Step-by-step explanation:

Neyman allocation is technique of sample allocation used in cases of stratified sampling.

The formula to compute the best sample size of each stratum is:

[tex]n_{h}=n\times \frac{(N_{h}\times SD_{h})}{\sum\limits^{k}_{i=1}(N_{i}\times SD_{i})}[/tex]

The information provided is:

[tex]N_{m}=50\\N_{c}=100\\n=20\\[/tex]

Compute the range for the number of people at the mountain campsite as follows:

[tex]R_{m}=6-1=5[/tex]

Then the standard deviation for the number of people at the mountain campsite will be:

[tex]SD_{m}=\frac{R_{m}}{4}=\frac{5}{4}[/tex]

Compute the range for the number of people along the coast campsite as follows:

[tex]R_{c}=10-1=9[/tex]

Then the standard deviation for the number of people along the coast campsite will be:

[tex]SD_{c}=\frac{R_{c}}{4}=\frac{9}{4}[/tex]

Compute the sample size for the mountain campsite as follows:

[tex]n_{m}=n\times \frac{(N_{m}\times SD_{m})}{(N_{m}\times SD_{m})+(N_{c}\times SD_{c})}[/tex]

    [tex]=20\times \frac{(50\times (5/4))}{(50\times (5/4))+(100\times (9/4))}\\\\=20\times 0.2174\\\\=4.348\\\\\approx 4[/tex]

Compute the sample size for along the coast campsite as follows:

[tex]n_{c}=n-n_{m}=20-4=16[/tex]

Thus, 4 samples should be from the mountain and 16 from along the coast.

X¹= -2 + 2√33

X²= -2 - 2√33

Step-by-step explanation:

X × (X+2) = 32

X² + 2X = 32

X² + 2X - 32= 0

Δ=132

X= -2 ± 2√33

X¹= -2 + 2√33

Answer:

62°

Step-by-step explanation:

If it is a right triangle, subtract 90, from 180 and then subtract 28 to get D.  D should = 62°

D must be equal to 28° in order for triangle ABC to be similar to triangle DEF.

The correct answer is option B.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

We know that if two angles of a triangle are congruent to two angles of another triangle, then the triangles are similar.

Since angle A is congruent to angle D, we need to find the value of D that makes this true.

Therefore,

D must be equal to 28° in order for triangle ABC to be similar to triangle DEF.
