Last year, Tim rode his bike a total of 50 3/8 miles. This year, he rode his bike a total of 258 3/4 miles. Which of the following explains about how much farther Tim rode his bike this year than last year? A. About 200 times farther; Subtract last year's distance from this year's distance to get 208 3/8.
Then round to the nearest hundred to get 200.

B. About 50 times farther; Round each distance to the nearest whole number.
Then multiply last year's distance by 50 to see that 259 is close to 50 × 5.

C. About 10 times farther; 258 is about 5 times 50, and 34 is 2 times 38, so multiply 5 × 2 to get 10.

D. About 5 times farther; Round each distance to the nearest whole number.
Then multiply last year's distance by 5 to see that 259 is close to 50 × 5.

Answer:

CSA of a cylinder = 144cm²

Step-by-step explanation:

Given the following data;

Base circumference = 36cm

Height = 4cm

To find the curved surface area (CSA) of the cylinder;

CSA of a cylinder = 2πr * h

But 2πr = 36cm

Substituting the values into the equation, we have;

CSA of a cylinder = 36 * 4

CSA of a cylinder = 144cm²

Answer:

19) Domain: - ∞ < x < ∞                    20) Domain:  - ∞ < x < ∞

Range: - ∞ < y < ∞                                  Range: - ∞ < y < ∞

Increases throughout                            Decreases throughout

Step-by-step explanation:

Given the parent function " y = ∛x" we know that the first graph should have a vertical shift down 2 units, and a horizontal shift 4 units to the right. There is no vertical stretch since there is no coefficient. (Check first graph)

Domain: - ∞ < x < ∞

Range: - ∞ < y < ∞

Increases throughout

______________________________

For the second graph there should be a vertical shift down three units, a horizontal shift 1 unit to the left, and a vertical stretch by a factor of - 1. (Check second graph)

Domain: - ∞ < x < ∞

Range: - ∞ < y < ∞

Decreases throughout

Answer:

y = 2x-6

Step-by-step explanation:

Slope intercept form:

y = mx+b

m = slope

b = The point where the line crosses the y-axis

So if you put it all together you get the answer of:

y = 2x-6

Answer:

About 5043.58

Step-by-step explanation:

The standard form for an exponential decay after t time is:

[tex]\displaystyle f(t)=a(r)^{t/d}[/tex]

Where a is the initial value, r is the rate decay, t is the time that has passed, and d is the amount of time it takes for 1 cycle.

The initial value is 9800. So a = 9800.

The quantity cuts in half. So, r = 1/2.

And it cuts in half every 6 days. For this question, we will convert this to hours. 6 days = 144 hours. So, we can let d = 144, where t will be in hours.

Therefore, our function is:

[tex]\displaystyle f(t)=9800\Big(\frac{1}{2}\Big)^{t/144}[/tex]

Where t is the amount of time that has passed, in hours.

Then the quantity left after 138 hours will be:

[tex]\displaystyle f(138)=9800\Big(\frac{1}{2}\Big)^{138/144}\approx 5043.58[/tex]

Answer:

we use the ASA when a triangle is conguerent by angle,side,angle.

SAS se when atriangle is conguerent by side,angle,side

sss when the triangle is conguerent by side,side,side

Answer:

ASA- The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

SAS- is a rule used to prove whether a given set of triangles are congruent. The SAS rule states that: If two sides and the included angle of one triangle are equal to two sides and included angle of another triangle, then the triangles are congruent.

SSS- If two triangles are congruent it means that all corresponding angle pairs and all corresponding sides are congruent. The SSS criterion for triangle congruence states that if two triangles have three pairs of congruent sides, then the triangles are congruent

Step-by-step explanation:

50% off makes the new price half of the original, then another 50 % would be half off the discounted price, so they actually end up paying 25 % of the original price:

50 % x 50 % = 25 %

Answer:

she was charged for 50% of the 50% off

Step-by-step explanation:

Lets say the original price was 100$ The store discounted it by 50% so it is now 50$ but the coupon take 50% off of that 50 so it would be 25$

Answer:

[tex]\{x:x>5\}[/tex]

Step-by-step explanation:

Given

[tex]12 - x < 7[/tex]

Required

Values of x that make it true

First: solve the inequality.

[tex]12 - x < 7[/tex]

Collect Like Terms

[tex]- x < 7-12[/tex]

[tex]- x < -5[/tex]

Multiply both sides by -1

[tex]-1 * - x < -5 * -1[/tex]

[tex]x > 5[/tex] --- The inequality changes when multiplied by a negative value

So, the solution implies that the value of x is greater than 5 (i.e. 6, 7, 8..)

Hence, the set is:

[tex]\{x:x>5\}[/tex]

Answer:

3/1 or 3

Step-by-step explanation:

7 1/3  = 7x3 + 1/3 =21 + 1/3 =22/3

7x3/3 = 21/3

-------------------------------------------------

2 4/9 2x9 + 4/9 = 18 + 4 /9= 22/9

2x9/9 = 18/9

Divide: 22/3 : 22/9 =22/3 x9/22 =

22/3 x 9/22 = 198/66 66/66 x 3/1 = 3

Answer:

(c) [tex]h(3) = 1[/tex]

Step-by-step explanation:

Given

The attached graph

Required

Find h(3)

The formula to use in solving this is:

[tex]y = h(x)[/tex]

Substitute 3 for x

[tex]y = h(3)[/tex]

From the attached graph, the value od x = 3 points to the value of y = 1.

So, we have:

[tex]y = 1[/tex]

Answer:

I believe there are 5

Step-by-step explanation:

if there are 4 friends and Mary then that makes 5 people in total.

Answer:

15 minutes

Step-by-step explanation:

400 to 2000(x5)

so, 3 times 5 is equal to 15 min

Step-by-step explanation:

step 1. properties of equality have an "=" in the equation.

step 2. properties of inequality have a <, <=, >=, or a >.

The width is 3.

A rectangular prism is 3d. This means that there are three dimensions being multiplied by each other to obtain the overall volume. We can use the equation V = lwh to solve this equation, with V being volume, and the following, length, width, height. Substituting in the values (and changing the mixed numbers to improper fractions for simplicity):

1035/4 = (15/2)(23/2)(w)

w = (1035/4)(2/15)(2/23)

w = 3

Step-by-step explanation:

step 1. x > -2 means numbers greater than -2 but not including -2.

step 2. you graph a single variable on a number line.

step 3. the graph would include an open circle above -2 (not equal to -2)

step 4. the line would go right of the open circle (greater than) and have an arrow at the end.

step 5. the answer is b.
