Answer:

142.5

Step-by-step explanation:

It is 142.5 because when finding area you have to do base x height our base here is 15 and are height is 9.5 so now that we know are base and height we just multiply! so 15 × 9.5 = 142.5 Hope this helps!

Answer:

C. 9 8/56

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Box contain = 512 grams

One serving = 56 gram

So, we can calculate the number of serving by using following formula,

Number of serving = Box contain ÷ One serving

By putting the value, we get

Number of serving = 512 ÷ 56

= 9.14 or 9 8/56

Answer:

The distance from the base of the building to the base of the ladder is 13.56 feet.

Step-by-step explanation:

This can be solved using Pythagorus theorem.

If the length of the ladder is taken as the hypotenuse and the distance from the building as the base of the triangle then the altitude can be found out by using

c²= a²+b²

Where c is the hypotenuse and b is the base and a is the altitude

Putting the values

25²= a²+ 21²

a²= 25²-21²

a²= 625-441

a²= 184

a= √184= 13.56 feet

The distance from the base of the building to the base of the ladder is 13.56 feet

Answer:

Cranberry juice needed to fill the bottle = 5.2 cups

Step-by-step explanation:

sports drink mix:

Orange juice = 25%

Cranberry juice = 65%

Sprite = 10%

His bottle holds 8 cups of drink.

How much cranberry juice does she need to fill the bottle?

Cranberry juice needed to fill the bottle = 65% of 8 cups

= 65/100 × 8

= 0.65 × 8

= 5.2 cups

Cranberry juice needed to fill the bottle = 5.2 cups

Orange juice needed to fill the bottle = 25% of 8 cups

= 25/100 × 8

= 0.25 × 8

= 2 cups

Orange juice needed to fill the bottle = 2 cups

Sprite needed to fill the bottle = 10% of 8 cups

= 10/100 × 8

= 0.1 × 8

= 0.8 cups

Sprite needed to fill the bottle = 0.8 cups

Answer:

The distance from the helicopter to the further observer is:

d = 12.77 miles

Step-by-step explanation:

The observer with 19.5° of elevation will be denoted by 1

The observer with 31.2° of elevation will be denoted by 2.

Here we have two right triangles. Both of them have the same opposite sides, so will be useful to use the tangent function.

For the second observer:

[tex]tan(31.2)=\frac{h}{x}[/tex] (1)

Where:

For the first observer:

[tex]tan(19.5)=\frac{h}{5+x}[/tex] (2)

Where:

Let's find x from equations (1) and (2). Both of them have the variable "h" so we can equal these equations.

[tex]xtan(31.2)=(5+x)tan(19.5)[/tex]

[tex]x(tan(31.2)-tan(19.5))=5tan(19.5)[/tex]

[tex]x=\frac{5tan(19.5)}{tan(31.2)-tan(19.5)}[/tex]

[tex]x=7.04\: miles[/tex]

Now, if we use the right triangle with 19.5° of elevation, the hypotenuse will be the distance from the helicopter and the further observer (let's call d).

Let's use the cosine function to find d.

[tex]cos(19.5^{\cric})=\frac{5+x}{d}[/tex]

[tex]d=\frac{5+7.04}{cos(19.5^{\cric})}[/tex]

[tex]d=12.77\: miles[/tex]

Step-by-step explanation:

puting right terms together to find value of y

Answer:y = 2

Step-by-step explanation:

IF we are solving for y...

20y + 60 = 100

Subtract 60 from both sides to get y by itself...

20y = 40

divide by 20 to get y...

y = 2

Answer:

Step-by-step explanation:

Area of triangle with angle of 30°:

[tex]A_1=\frac12\cdot 5^2\cdot\sin(30^o)=\dfrac{25}4=6.25[/tex]

Area of triangle with angle of 50°:

[tex]A_2=\frac12\cdot 5^2\cdot\sin(50^o)=\dfrac{25}2\cdot0.766=9.575[/tex]

Area of the rest of the figure:

[tex]A_3=\dfrac{(360-30-50)^o}{360^o}\cdot\pi\cdot5^2=\dfrac79\cdot\pi\cdot25 =61.087[/tex]

Therefore:

                  [tex]A=A_1+A_2+A_3=6.25+9.575+61.087=76.912[/tex]

Answer:

(Choice A) A More rainfall relates to more mosquitoes, as long as rainfall is less than 2 cm²

Step-by-step explanation:

The given function for the number of mosquitoes, (by analysis of the options) is, g(x) = 4·x - x²

Where;

x = The amount of rainfall

g(x) = The number of mosquitoes in millions

The given function can be expressed as follows;

g(x) = 4·x - x² + 0

The maximum point is given by g'(x) = d(4·x - x²)/dx = 4 - 2·x = 0

At the maximum (turning point), we have;

4 - 2·x = 0

4 = 2·x

x = 4/2 = 2

The level of rainfall that gives the maximum number of mosquitoes is, x = 2 cm²

The number of mosquitoes increases from zero rainfall up to the maximum number of 4 million mosquitoes at 2 cm² rainfall and then decreases to zero as the rainfall increases further more than 2 cm², as shown in the attached  graph of the function g(x) that models the number of mosquitoes created with MS Excel

Therefore, the true statement is (Choice A) more rainfall relates to more mosquitoes, as long as (the level of) rainfall is less than (the maximum) 2 cm².

Answer:

B. 9

Step-by-step explanation:

The probability of landing on A is 3/8. Now, multiply the fraction by the number of times it will be spun.

3/8 × 24 = 9

Hope this helps!

Answer:

9 times

Step-by-step explanation:

Probability for landing on A is 3/8. So, for every 8 times you spin, you predict that you will land on A 3 times (3 times out of 8 spins).

So you either

A.) multiply the probability by the total spins:

(3/8) * (24) = 9 times you land on A

or

B.) divide the 24 spins by 8, to get 3 different repeats of the probability.

So 3 * 3 = 9 times.

Answer:

b

Step-by-step explanation:

An explicit formula for a sequence allows you to find the value of any term in the sequence. ... A recursive formula for a sequence allows you to find the value of the nth term in the sequence if you know the value of the (n-1)th term in the sequence.

The explicit formula will be best used in finding the 7th term when the first term is -1 and the common difference is 10, the correct option is B.

A recursive formula is used to determine the nth term when (n-1) th term is given in the series.

The Explicit formula is when any term of the sequence has to be determined on the basis of the first term and the common difference.

The recursive formula just requires one operation, while the explicit formula requires multiple operations,

The recursive formula is limited to determining the consecutive terms while the explicit formula can be used to determine any term of the sequence.

The explicit formula will be best used in finding the 7th term when the first term is -1 and the common difference is 10.
