Answer:

It would take 3 hours to travel 135 miles.

Step-by-step explanation:

[tex]\frac{900}{135} =\frac{20}{x}[/tex]

So, if you cross multiply 135 by 20 that equals 2,700

Next, 2,700 divided by 900= 3

It would take 3 hours to travel 135 miles.

Answer:

75 cm

Step-by-step explanation:

It is given that the triangles are similar. It means that the ratio of their areas are equal to the ratio of their bases and ratio of their altitudes.

Let [tex]A_1[/tex] be the area of 1st triangle.

Let [tex]A_2[/tex] be the area of 2nd triangle.

Let [tex]h_1[/tex] be the altitude of 1st triangle.

Let [tex]h_2[/tex] be the altitude of 2nd triangle.

Let [tex]b_1[/tex] be the base of 1st triangle.

Let [tex]b_2[/tex] be the base of 2nd triangle.

Then [tex]A_1: A_2 = h_1 : h_2 = b_1 : b_2 ...... (1)[/tex]

[tex]A_1 = 42 cm^{2} \\A_2 = 262.5 cm^{2}\\h_1 = 7 cm\\b_2 = ?[/tex]

We know that area of a triangle is:

[tex]A = \dfrac{1}{2} \times b \times h[/tex]

Area of smaller triangle:

[tex]\frac{1}{2} \times b_1 \times 7 = 42\\\Rightarrow b_1 = 12 cm[/tex]

Now, using part of equation (1):

[tex]A_1: A_2 = b_1 : b_2 \\\Rightarrow \dfrac{42}{262.5} = \dfrac{12}{b_2}\\\Rightarrow b_2 = 75 cm[/tex]

Hence, base of larger triangle = 75 cm

A 2-column table with 3 rows is titled Recipe 1. Column 1 is labeled Honey (tablespoons) with entries 8, 10, 12. Column 2 is labeled Oats (cups) with entries 4, 5, 6.

Which recipe has the greatest ratio of honey to oats?

Solution

Computing the ratio of honey to oats for each of recipes

Recipe 1

Honey | 5 | 10 | 15

Oats | 2 | 4 | 6

Honey to Oats ratio = (5/2) = (10/4) = (15/6) = 2.5 to 1.

Recipe 2

Honey | 6 | 10 | 14

Oats | 3 | 5 | 7

Honey to Oats ratio = (6/3) = (10/5) = (14/7) = 2 to 1.

Recipe 3

Honey | 3 | 6 | 9

Oats | 1 | 2 | 3

Honey to Oats ratio = (3/1) = (6/2) = (9/3) = 3 to 1.

Recipe 4

Honey | 8 | 10 | 12

Oats | 4 | 5 | 6

Honey to Oats ratio = (8/4) = (10/5) = (12/6) = 2 to 1.

Recipe 3 evidently has the greatest honey to oats ratio amongst the 4 recipes.

Hope this Helps!!!

Answers:

A.) 8 is the outlier in the set. It is the only number that doesn't match with the others. It is the furthest from the median of the numbers.

B.) The outlier could represent false information. It could greatly drop the number of the mean, or the average, range of the scores.

C.) The mean is affected more. The mean of a set of numbers is the average of the set. The median just locates the middle-most number. The median would not always give an accurate representation of the average of the set like the mean would.

Answer:

The softball team needs to raise more money per person.

Step-by-step explanation:

To calculate what you need in each team you have to divide the money you need by the number of players in each team, because each one contributes an equal amount.

The softball team needs to raise $ 318.12 between the twelve girls on the team:

318.12 / 12 = 26.51

$ 26.51 each girl needs to contribute

The hockey team needs to raise $ 391.92 between the 24 boys on the team

391.92 / 24 = 16.33

$ 16.33 each boy needs to contribute

Therefore, the softball team needs to raise more money per person.

Answer: A = 5

Step-by-step explanation:

I'll rewrite this as fractions.

[tex]\frac{A}{20}=\frac{4}{16}[/tex]

Solve for A,

[tex]A=5[/tex]

Answer:

[tex] (x_1 = 94 , y_1 = 60)[/tex]

[tex] (x_2 =96 ,y_2 = 66)[/tex]

And we can estimate the slope with the following formula:

[tex] m =\frac{y_2 -y_1}{x_2 -x_1}= \frac{66-60}{96-94}=3[/tex]

And we can find the intercept using the first point given for example:

[tex] 60 = 3*94 +b[/tex]

And solving for b we got:

[tex] b = 60 -282 = -222[/tex]

And the model would be given by:

[tex] y = 3x -222[/tex]

Step-by-step explanation:

For this case we can assume that the interest is find an equation for the times per minute with the temperature. So then the independent variable (x) would be the temperature and the dependent (y) the times per minute. We want to adjust a linera model like this one:

[tex] y = mx +b[/tex]

We have the following info given:

[tex] (x_1 = 94 , y_1 = 60)[/tex]

[tex] (x_2 =96 ,y_2 = 66)[/tex]

And we can estimate the slope with the following formula:

[tex] m =\frac{y_2 -y_1}{x_2 -x_1}= \frac{66-60}{96-94}=3[/tex]

And we can find the intercept using the first point given for example:

[tex] 60 = 3*94 +b[/tex]

And solving for b we got:

[tex] b = 60 -282 = -222[/tex]

And the model would be given by:

[tex] y = 3x -222[/tex]

Answer:

Step-by-step explanation:

Let " x "  denotes the temperature in degree Fahrenheit .

Let  " y " denotes the chirp rate per minute .

We have given that at 94 degree Fahrenheit , chirp rate is 64 times per minute and at 96 degree Fahrenheit , it is 118 times per minute .

We write this information in coordinate form ( x,y) .

We have ( x₁ ,y₁)  = ( 94 , 60 )  and  ( x₂ , y₂) = ( 96,66) .

                        y₂   - y ₁                     66  -   60                  6

Slope , m  =  ----------------------  =    ---------------------  =     -----------

                         x₂  - x₁                        96   -  94                   2

          Slope , m =  6/2 = 3 .

Equation of line in slope intercept form is

y = m x + b  where  ' m' is slope and ' b ' is intercept .

Plug value of m  , we get

y = 3 x + b .

To find value of b , we put ( 94 , 60 ) in place of x and y .

Put x = 94 and y = 60 , we get

60 = 3 * 94 + b

60  = 282 + b

60 - 282 =  b

- 222 = b

Thus we get b = - 222 .

So the equation become

y = 3 x - 222 .

Answer:

0.7048

Step-by-step explanation:

∫₂⁴ 1 / (x − 1)² dx

n = 4, so we divide the interval into 4 regions.  The width of the regions is:

(4 − 2) / 4 = 0.5

So the intervals are (2, 2.5), (2.5, 3), (3, 3.5) and (3.5, 4).

Evaluate f(x) at the ends of each interval.

f(2) = 1

f(2.5) = 4/9

f(3) = 1/4

f(3.5) = 4/25

f(4) = 1/9

Find the area of each trapezoid:

A₁ = ½ (2.5 − 2) (1 + 4/9) = 13/36

A₂ = ½ (3 − 2.5) (4/9 + 1/4) = 25/144

A₃ = ½ (3.5 − 3) (1/4 + 4/25) = 41/400

A₄ = ½ (4 − 3.5) (4/25 + 1/9) = 61/900

So the total approximate area is:

A = 0.705

Closest answer is 0.7048.

The value of expression is,

⇒ 0.7048

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

⇒ ∫₂⁴ 1 / (x − 1)² dx

Now, For n = 4, we divide the interval into 4 regions.  

Hence, The width of the regions is:

= (4 − 2) / 4

= 0.5

Thus, the intervals are,

⇒ (2, 2.5), (2.5, 3), (3, 3.5) and (3.5, 4).

Thus, We can evaluate f(x) at the ends of each interval as,

f(2) = 1

f(2.5) = 4/9

f(3) = 1/4

f(3.5) = 4/25

f(4) = 1/9

Hence, the area of each trapezoid are,

A₁ = 1/2 (2.5 − 2) (1 + 4/9) = 13/36

A₂ = 1/2 (3 − 2.5) (4/9 + 1/4) = 25/144

A₃ = 1/2 (3.5 − 3) (1/4 + 4/25) = 41/400

A₄ = 1/2 (4 − 3.5) (4/25 + 1/9) = 61/900

Therefore, the total approximate area is:

A = A₁ + A₂ + A₃ + A₄

A = 0.7048

Answer:

x=1  y=3

Step-by-step explanation:

y = 4x - 1

y = -3x + 6

Set the two equations to each other

4x - 1  = -3x + 6

Add 3x to each side

4x +3x - 1  = -3x+3x + 6

7x-1 =6

Add 1 to each side

7x-1+1 = 6+1

7x= 7

Divide each side by 7

7x/7 = 7/7

x=1

Now we can find y

y = 4x-1

y = 4(1)-1

y = 3

Answer:

x = -3

In-Depth Steps:

1.) Start with the bottom equation: [tex]x+2y=-3[/tex]

2.) Set [tex]x[/tex] alone on one side of the equal sign. Your equation will look like [tex]3+2y=x[/tex].

3.) Plug [tex]3+2y[/tex] in for [tex]x[/tex] in the first equation. You will get [tex]2(3+2y)+5y=6[/tex].

4.) Distribute. Your equation now looks like this: [tex](6+4y)+5y=6[/tex].

5.) Combine like terms. You will get [tex]6+9y=6[/tex].

6.) Subtract 6 from both sides. You get [tex]9y=0[/tex]. We can learn that Y=0.

7.) Go back to either equation and put 0 in for y.

8.) In the top equation, it would look like [tex]2x=6[/tex] and the bottom equation would look like [tex]x=-3[/tex]. We basically got our answer of [tex]x = -3[/tex], but we will plug it into the [tex]2x=6[/tex] equation, and in-fact, we get x = -3.

Answer:

Bronze

Step-by-step explanation:

To know the metal used to produce necklace, we must calculate the density of the necklace. This is illustrated below below:

Mass of necklace = 192g

Volume = 19.5cm^3

Density =...?

Density of a substance is simply defined as the mass of the substance per unit volume.

Density = Mass /volume

Density = 192g / 19.5cm^3

Density = 9.85g/cm^3

Now comparing the density of the necklace with the density of various metals in the table, we can see that the density of the necklace matches that of bronze.

Therefore, the necklace is made of bronze.
