Shanice wanted to make note cards by
cutting pieces of paper in half. Before
starting she got two more pieces to use.
When she was done she had 20 half-pieces
of paper. With how many pieces did she
start?

Answers

Answer:

8 pieces of paper

Step-by-step explanation:

Since the paper was cut into two, divide the half-pieces by 2 go get the amount of full-sized paper. And since Shanie got 2 more pieces of paper before she started, you subtract 2 from 10, which leaves you with 8 pieces of full-sized paper.

A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 60.0 min at 95.0 km/h, 10.0 min at 55.0 km/h, and 35.0 min at 45.0 km/h and spends 50.0 min eating lunch and buying gas.
(a) Determine the average speed for the trip. km/h
(b) Determine the distance between the initial and final cities along the route. km

Answers

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

(b) Total distance,

[tex]D=v_1t_1+v_2t_2+v_3t_3+v_4t_4\\\\D=95\times \dfrac{60}{60}+55\times \dfrac{10}{60}+45\times \dfrac{35}{60}+0\times 50\\\\D=130.41\ \text{km}[/tex]

The distance between the initial and final cities along the route is 130.41 km.

What is the solution for the inequality 5−3x>26?

Enter your answer as the correct inequality. For example, if your answer is x>42, enter your answer like this: x>42

Answers

Answer:

5−3x>26

Subtract 5 from each side

5-5−3x>26-5

-3x > 21

Divide each side by -3, remembering to flip the inequality

-3x/-3 < 21/-3

x < -7

Answer:

x < -7

Step-by-step explanation:

5 - 3x > 26

5 - 3x -5 > 26 - 5

-3x > 21

-3x ÷ -3 < 21 ÷ -3

x < -7

If m∠2=40°, what is the measure of ∠1 + ∠6?

Answers

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°

Action figures are $8 a piece at a toy store. The toy store sold 26 action figures today. How much money did the toy store receive from selling action figures today?

Answers

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

Find the values of x and y

Answers

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

2km: 3400m​

Answers

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]

Identify the initial value, a, and base, b, of the function f(x)=ab^x if its graph passes through the points (0, 4) and (1, 20)

Answers

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
