Answer:

6 miles

Step-by-step explanation:
Area is :

[tex]A = \frac{1}{2} hb[/tex]  OR [tex]A = \frac{hb}{2}[/tex]
So base is :
[tex]b = 2 \frac{A}{h}[/tex]
Substituting values given:
b = 2 × (13.5÷4.5)
b = 2×3
b=6

Answer:

the length of the base= 6miles

Step-by-step explanation:

Area of triangle =1/2 *Base*Hight

Now we sub the values in the formula:

13.5 = 1/2 * (length of the base) * 4.5

length of the base = (2 * 13.5)/4.5

length of the base = 6 miles

Answer:

32 m, 80 m^2

Step-by-step explanation:

Ratio of their sides = 12 : 8 = 3 : 2

Ratio of their perimeter = 3 : 2

so 48 : perimeter of smaller triangle = 3 : 2

Perimeter of smaller triangle = 48 * 2 / 3 = 32 m

Ratio of their areas = 3^2 : 2^2 = 9 : 4

so 180 : area of smaller triangle = 9 : 4

Area of smaller triangle = 180 * 4 / 9 = 80 m^2

It appears the graph goes through (0,3) and (5,6)

If so, then you have the correct slope and y intercept.

The formula is [tex]C = \frac{3}{5}n+3[/tex] which is the same as writing C = (3/5)n+3

Don't forget about the parenthesis around the 3/5.

We can verify this by plugging in n = 0 and you should get C = 3.

Also, if n = 5 then it leads to C = 6.

Answer:a=70

c=110

b=110

Step-by-step explanation:

The solution is in the attached file filatache

Answer:

A = 70

B = 110

C = 110

Step-by-step explanation:

A is opposite of the 70 degree angle, and vertical angles are equal, so it is also 70 degrees.

A straight line is 180 degrees, so 70 + B = 180, making B = 110 degrees.

Both of these rules apply for C, making it also 110 degrees.

Step-by-step explanation:

Functions of functions are evaluated by taking first's output as second's input. The representation of [tex]f[g(x)][/tex] is:  Option D: [tex]f[g(x)] = 2x^2 + 21[/tex]

Functions which are formed by composing two or more functions in a way that one's output is another's input are called composite functions. They are also called function of functions.

The given functions are

Then [tex]f[g(x)][/tex] will be evaluated as output of g(x) taken as input for f(x).

Thus,

[tex]f[g(x)] = 2[g(x)] + 5 = 2[x^2 + 8] + 5\\\\f[g(x)] = 2x^2 + 21[/tex]

[tex]f[g(x)] = 2[g(x)] + 5 = 2[x^2 + 8] + 5\\\\f[g(x)] = 2x^2 + 21[/tex]

Thus,

The representation of [tex]f[g(x)][/tex] is:  Option D: [tex]f[g(x)] = 2x^2 + 21[/tex]

Answer:

  b. The variable will always be the letter x (false)

Step-by-step explanation:

Variables can be any letter or symbol. The letter x is often used as a variable, but that is not the only choice. Many formulas, for example, make use of variables that have letters reminding you what they stand for.

For example, the formula ...

  A = 1/2(b1 +b2)h

uses the variables A, b1, b2, and h to represent area, base-1, base-2, and height, respectively. The letter x is not used at all.

A room area

Lenght × Width = 16 × 12

= 192 square feet

1 square yard = 9 square feet

so 1 square feet = 1/9 square yard

192 square feet = 192 × 1/9 square yard

= 64/3 square yard

Answer:

Although it would be great to see the picture of your problem, Acute angles are usually smaller than a right angle. A right angle is half of a straight line. A straight line is exactly how it sounds. An obsute angle is bigger than a right angle, so it has a higher degree.

Answer:

0.106

Step-by-step explanation:

100 meters= 382 feet (per hour)

60 minutes in an hour

60 seconds in a minute

382/60=6.34 inches per minute (rounded to nearest tenth)

1 minute = 6.34 inches

6.34 / 60 = 0.106 (rounded to nearest thousandth)

Answer:

Total Surface Area: 65.97 cm²

Lateral Surface Area: 37.70 cm²

Step-by-step explanation:

You can solve for the surface area without the height or you can solve for the height and then find the surface are, either way is easy.

Lets first solve without the height. We will solve the surface area with the radius and slant height.

Total Surface area of cone formula: πr (r + s)

Curved surface are formula: πrs

Substitute the values in the picture with the formula

Slant height: 4

Radius: 3

πr (r + s)

π(3)(3 + 4)

(3.141593)(3)(3 + 4)

=9.424778(3 + 4)

=(9.424778)(7)

=65.973446

65.973446 rounded to the nearest hundredth is 65.97
TSA = Total Surface Area

TSA = 65.97 cm²

Now to find the curved surface area or some people call it the Lateral Surface Area

Formula: πrs

Radius: 3

Slant Height: 4

π(3)(4)

(3.141593)(3)(4)

=(9.424778)(4)

=37.699112

37.699112 to the nearest hundredth is 37.70

CSA = Curved Surface Area

CSA = 37.70 cm²

If you choose to compute the height (h) the you have to know both the radius (r) and the slant height (s):

Formula: height (h) = √s² - r²

Slant height = s = 4

Radius = r = 3

Height = h = ?

Now substitute the values into the formula

h = √s² - r²

h = √4² - 3²

h = √16 - 9

h = √7

h = 2.64575131

Height: 2.64575131 cm

Now it's time to find the surface area and curved surface area, now that you have the height:

Surface area formula given height and radius: πr(r + √(r² + h²))

Substitute the values

Height: 2.64575131
Radius: 3

πr(r + √(r² + h²))

π(3)(3 + √(3² + 2.64575131²))

TSA = (3.141593)(3)(3 + √(3² + 2.64575131²)

TSA = 9.424778(3 + √(3² + 2.64575131²)

TSA = 9.424778(3 + √(9 + 7)

TSA = 9.424778(3 + √(16)

TSA = 9.424778(3 + 4)

TSA = 9.424778(7)

TSA = 65.973446

TSA = 65.97

Next, time to find the Curved surface area:

Formula: CSA = πr√(r² + h²)

CSA = πr√(r² + h²)

Substitute the values into the formula

Radius: 3

Height: 2.64575131

Slant Height: 4

CSA  = πr√(r² + h²)

CSA = π(3)√(3² + 2.64575131²)

CSA = 9.424778√(3² + 2.64575131²)

CSA = 9.424778√(9 + 7)

CSA = 9.424778√(16)

CSA = 9.424778(4)

CSA = 37.699112

CSA = 37.70

So, we can conclude that the Total Surface Area is 65.97 and the Lateral Surface Area is 37.70.

The number of rats in the sample are less than 30, therefore, according

to the central limit theorem, cannot approximate the population.

Response:

a) Should not be used because the Large Counts Condition is violated

The proportion of the rats given M that succeeded, [tex]\hat p_1[/tex] = 7 ÷ 10 = 0.7

The proportion of the control rats that succeeded, [tex]\hat p_2[/tex] = 2 ÷ 10 = 0.2

H₀: [tex]\hat p_1[/tex] = [tex]\hat p_2[/tex]

Hₐ: [tex]\hat p_1[/tex] > [tex]\hat p_2[/tex]

The z-test formula for the difference between two proportion is given as follows;

[tex]Z= \mathbf{\dfrac{\hat{p}_1-\hat{p}_2}{\sqrt{\hat{p} \cdot (1-\hat{p})\left (\dfrac{1}{n_{1}}+\dfrac{1}{n_{2}} \right )}}}[/tex]

Where;

[tex]\hat p = \dfrac{7 + 2}{10 + 10} = 0.45[/tex]

[tex]Z=\dfrac{0.7-0.2}{\sqrt{0.45\times (1-0.45) \times \left (\dfrac{1}{10}+\dfrac{1}{10} \right )}} \approx \mathbf{ 2.25}[/tex]

p = 1 - p(z < 2.25) = 1 - 0.9878 = 0.0122

However, the number of rats in the sample, n are less than 30

Therefore;

The sample is not large enough for the test compared to the population,
