The y values of the t-table for the function y=3

Mathematics

For the function y = 3, all y values will be 3, no matter the value of x.

This function is simply a straight line, and so it has a slope of 0.

However, it is a legitimate function.

Answer:

y=5x+1

Step-by-step explanation:

If you look closely at each side, you will see that the x increases by one and the y increases by five.

To get to zero (0) from one (1), you need to substract one.

Every time one is subtracted for x, 5 is subtracted from y.

6-5=1

viktelen [127]

Answer:

Step-by-step explanation:

As per divisibility rule, a number is divisible by 2 when one's place has the number 0,2,4,6 or 8

As per divisibility rule, a number is divisible by 5 when one's place has the number 0 or 5

As per divisibility rule, a number is divisible by 10 when one's place has the number 0

So, if a number is divisible by 2,5 and 10, then the number one's place should have 0

AREA, PERIMETER & VOLUME QUESTION

MrRissso [65]

Answer:

1. Case B

2. 9 cm³

3. 20 cm.

4. 4.5 m³

Step-by-step explanation:

Question 1: We are required to fit a drum having volume 14,000 cm³.

We know that the volume of cylinder = πr²h, where r is the radius and h is the height. So, according to the cases:

A. Here, r = 100 mm = 10 cm, h = 300 mm = 30 cm.

So, volume of the drum = πr²h = $\pi \times 10^{2} \times 30$ = 9424.78 cm³.

We cannot put the given drum inside this drum.

B. Here, r = 200 mm = 20 cm, h = 30 cm.

So, volume of the drum = πr²h = $\pi \times 20^{2} \times 30$ = 37699.11 cm³.

C. Here, r = 32 cm, h = 250 mm = 25 cm.

So, volume of the drum = πr²h = $\pi \times 32^{2} \times 25$ = 80424.77 cm³.

Out of options B and C, the smallest volume is in CASE B i.e. 37699.11 cm³.

So, Case B is the correct option.

Question 2: We have the dimensions of the speaker as,

Length = 45 cm = 0.45 m, Width = 0.4 m, Height = 50 cm = 0.5 m

Now, Volume of a cuboid = L×W×H

Thus, volume of the speaker = 0.45 × 0.4 × 0.5 = 0.09 m³ = 9 cm³.

Question 3: We have that the volume of the speaker is 30,000 cm³.

Also, Length = 30 cm = 0.45 m, Height = 500 mm = 50 cm.

So, volume of the speaker = L×W×H

i.e. 30,000 = 30 × W × 50

i.e. W = $\frac{30,000}{1500}$

i.e. W = 20 cm.

Hence, the width of the speaker is 20 cm.

Question 4: We have the dimensions as,

Base= 2 m, Length = 3 m, Height = 1.5 m

So, the volume of prism = $\frac{base\times height}{2} \times length$

i.e. Volume = $\frac{2\times 1.5}{2} \times 3$

i.e. Volume = 4.5

Thus, volume of the sand needed to be filled is 4.5 m³.

Which situation could the expression −255 represent? A Each of 5 golfers has the same score after 9 holes. The total of their sc

Alex

Answer and explanation:

Not sure if the question is complete or valid but I will explain each option:

Let's assume the question asks which of the options would provide a negative result of -25( as no option evaluates to -255)

A. There would be a negative result here since all golfers have a negative score of -5 after 9 holes, and therefore a total score of -25 for all five golfers

B. Temperature increases by 25 degrees after 5 hours hence 5 degrees increase for every 1 hour. This would obviously give a positive result.

C. A football team gains 25 yards in the first play and loses 5 yards in the second but has a result of 5 yards gained in total. Hence there was a penalty of losing 20 yards for a loss of 5 yards= 25 yards- 20 yards= 5yards

D. Alyson withdraws $25 every week for 5 weeks, therefore she withdraws $125 in 5 weeks. This would be a negative result of -$125.
