Answer:

13.5 miles or 27/5 miles

Step-by-step explanation:

2 7/10 is equal to 2.7  If she plans to run 5 times as much as last week, multiply 2.7 by 5.

2.7*5=13.5

=15,750

Answer:

1) B

2) About 5°.

Step-by-step explanation:

1)

We can use the following co-function identity:

[tex]\sin(\theta)=\cos(90-\theta)[/tex]

Substitute A for θ:

[tex]\sin(A)=\cos(90-A)[/tex]

Since we know that sin(A) is 1/3, this means that cos(90-A) must also be 1/3.

So, our answer is B.

2)

Refer to the drawing.

Remember that 1-inch rise is a height of 1 while a 12 inch length is a length of 12.

So, to find the maximum ramp angle, we simply need to find the value of x.

We know the sides opposite and adjacent to x. So, we can use tangent:

[tex]\tan(x)=\text{opp}/\text{adj}[/tex]

Substitute 1 for the opposite side and 12 for the adjacent side:

[tex]\tan(x)=1/12[/tex]

Take the inverse tangent of both sides:

[tex]x=\tan^{-1}(1/12)[/tex]

Use a calculator. Make sure you're in Degrees mode:

[tex]x\approx4.76\textdegree\approx5\textdegree[/tex]

So, the maximum ramp angle should be about 5°

The toy store received $208 from selling action figures.

Knowing that each action figure is $8 in the toy store, we can multiply that by the quantity of action figures sold to get the total amount of money received.

26 times $8 is $208.

Answer:

$208

Step-by-step explanation:

If the toys are $8 a peice and they sold 24 toys then they would recive $208. Think of it this way: if you multiply 8 times 2 you get 16, then you multiply 16 by 10 to represent 20 of the action figures. That would get you $160. Then multiply 8 times 6, and that gets you 48. Now add those two together. 160+48=$208

Answer:

[tex]\displaystyle \frac{10}{17}[/tex]

Step-by-step explanation:

Fraction Simplifying

We are given the ratio 2 Km:3400 m. This can be written in fraction form as:

[tex]\displaystyle \frac{2\ km}{3400\ m}[/tex]

Since 2 Km = 2000 m:

[tex]\displaystyle \frac{2\ km}{3400\ m}=\frac{2000\ \not{m}}{3400\ \not{m}}[/tex]

We need to simplify the fraction:

[tex]\displaystyle \frac{2000}{3400}[/tex]

We cancel out two zeroes, which is like dividing both numbers by 100:

[tex]\displaystyle \frac{20\not{0}\not{0}}{34\not{0}\not{0}}[/tex]

The remaining fraction is:

[tex]\displaystyle \frac{20}{34}[/tex]

Dividing both by 2:

[tex]\displaystyle \frac{10}{17}[/tex]

Since the denominator is a prime number, no more simplifying is possible, thus the given ratio is equivalent to:

[tex]\boxed{\displaystyle \frac{10}{17}}[/tex]

Answer:

x = 29.44

y = 34

Step-by-step explanation:

For this problem, we will simply use trigonometry to find the values of y and x for the given triangle.

The two trigonometric functions we will use are tangent and sine.

The general form for tangent is:

tan (Θ) = opposite / adjacent

The general form for sine is:

sin (Θ) = opposite / hypotenuse

For our given triangle, let's solve for x.

tan (30) = 17 / x

x * tan(30) = (17 / x) * x

x tan(30) = 17

x tan(30) * ( 1 / tan(30) ) = 17 * ( 1 / tan(30) )

x = 17 / tan(30)

x = 29.44

Now, let's solve for y.

sin (30) = 17 / y

y * sin(30) = (17 / y ) * y

y sin (30) = 17

y sin (30) * ( 1 / sin(30) ) = 17 * ( 1 / sin(30) )

y = 17 / sin(30)

y = 34

Hence, the values of x and y in our triangle are as follows:

x = 29.44

y = 34

The distance between -4 and 8 on a number line is 12.

To find the distance between -4 and 8 on a number line, you can subtract the smaller number from the larger number. In this case:

Distance = |8 - (-4)|

To subtract a negative number, you can think of it as adding the absolute value of that negative number:

Distance = |8 + 4|

Now, perform the addition:

Distance = |12|

The absolute value of 12 is 12, so the distance between -4 and 8 on a number line is 12 units.

Hence, the distance between -4 and 8 on a number line is 12.

Step-by-step explanation:

(a) The average speed of a person for the trip is given by total distance traveled divided by total time taken.

[tex]V=\dfrac{d_1+d_2+d_3+d_4}{t_1+t_2+t_3+t_4}[/tex]

Since, distance = velocity × time

Also, 1 hour = 60 min

[tex]V=\dfrac{v_1t_1+v_2t_2+v_3t_3+v_4t_4}{t_1+t_2+t_3+t_4}\\\\V=\dfrac{95\times \dfrac{60}{60}+55\times \dfrac{10}{60}+45\times \dfrac{35}{60}+0\times 50}{\dfrac{60}{60}+\dfrac{10}{60}+\dfrac{35}{60}+\dfrac{50}{60}}\\\\V=50.48\ \text{km/h}[/tex]

The average speed for the trip is 50.48 km/h

Answer:

a = 4, b = 5

Step-by-step explanation:

Given the exponential function

f(x) = a[tex]b^{x}[/tex]

Use the given points to find a and b

Using (0, 4 ) , then

4 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ) , thus

a = 4 , so

f(x) = 4[tex]b^{x}[/tex]

Using (1, 20 ) , then

20 = 4b ( divide both sides by 4 )

b = 5

Answer:

180°

Step-by-step explanation:

The diagram for this question has been attached to this response.

From the diagram;

(i) ∠2 and ∠6 are equal since they are corresponding angles. This implies that the measure of angle 2 (m∠2) is equal to the measure of angle 6 (m∠6). i.e

m∠2 = m∠6       ---------(a)

But m∠2 = 40°

Substitute this into equation (a) as follows;

40° = m∠6

∴ m∠6 = 40°

(ii) ∠1 and ∠2 are supplementary. This implies that the sum of the measures of angle 1 (m∠1) and angle 2(m∠2) is equal to 180°. i.e

m∠1 + m∠2 = 180°      ------------------(b)

But m∠2 = 40°

Substitute this into equation (b) as follows;

m∠1 + 40° = 180°

m∠1 = 180° - 40°

m∠1 = 140°

(iii) The measure of ∠1 + ∠6 is given by;

m∠1 + m∠6

Substitute the values of m∠1 = 140° and m∠6 = 40° into the expression to get

m∠1 + m∠6 = 140° + 40°

m∠1 + m∠6 = 180°

Therefore the measure of  ∠1 + ∠6 is 180°
