Answer:

Step-by-step explanation:

Given equation:

[tex]\sf \dfrac{t}{3}=2.78[/tex]

Multiply by 3 on both sides of the equation:

[tex]\implies \sf \dfrac{t}{3} \times 3=2.78 \times 3[/tex]

[tex]\implies \sf t=8.34[/tex]

Substitute 8.34 for t to check the solution:

[tex]\implies \sf \dfrac{8.34}{3}=2.78 \quad \leftarrow \: correct![/tex]

Answer:

Options 1, 4, and 5

Step-by-step explanation:

In order to solve an equation, the most key rule to remember is that whatever you do to one side, you must do the same to the other side.

This ensures that the equation will remain true.

In order to solve this given equation, we need to isolate the variable t.

We currently have:

t/3=2.78

To isolate t, we must "undo" dividing by 3.

The inverse of division is multiplication, so we can undo the operation by multiplying both sides of the equation by 3.

3 * t/3 = 2.78*3

Simplify

t=8.34

Since t=8.34, it is with this value that we should check the solution.

We can plug 8.34 in for t to see if the equation is true.

8.34/3=2.78

2.78=2.78

Since this is true, we know that we have solved the equation correctly.

We can solve this by calculating the arch lengths on the track and adding them to the straight lengths on the track.

To calculate the arch lengths, we can pretend the arches are semicircles and calculate the arch length. We know that the diameter is 100 meters, and the circumference formula is diameter times pi. 100 times pi is 314, using 3.14 as pi, but we divide this by two since we are calculating the arch length of a semicircle, not a full circle. Dividing 314 by two gives us 157. However, we multiply this by two since we have to include the other arch's length and the lengths are the same, giving us 314 again. adding this to 200, the straight side lengths of the track, we get our final answer, 514 meters.

Answer:

7 ounces.

Step-by-step explanation:

7/8 is on the line, and Habika has 7/8 of a pound of pretzels. If you divide 7/8 by two, you get 0.4375 of a pound of pretzels.

(On the number line, you can put it on the 4th line from 0, about 4.5/10 to 5.)

0.4375 of a pound converted to ounces is 7 ounces.

Therefore, your answer will be 0.4375 of a pound of pretzels. (about 0.44) which is 7 ounces.

Step-by-step explanation:

remember PEMDAS: parenthesis, exponents, multiply, divide, add, subtract ex: 5×(-2)=-10×3=-30

Part 1: It is most definitely Unit 2. I know this because there are more dots on the left side of Unit 2 than there are on Unit 1.

Unit 2 has 24 dots in total while Unit 1 has 25.

Part 2: Mean = 13 (13.44)

Mean Absolute Deviation = 3 (2.848)

Part 3: The results from part B prove my hypotheses from part A. How? The mean and MAD of Unit 1 are smaller than Unit 2's measurements, which I will not include because the question says only Unit 1 test measurements.

Answer:

The first two is x=60

Step-by-step explanation:

1.5/90 = 1/x

1.5x = 90 x 1

1.5x/1.5 = 90/1.5

x = 60

Answer:

a.  90/ 4.5 = 20 flags per yard

b.  4.5/ 90 = 0.05  = 5 hundredths of a yard

c. 0.75 x 3 colours = 2.25 yards

4.5 = 90 flags so 4.5/2 = 2.25 = 45 flags

Justifies she is correct when saying 45 flags can be made with 3 x 0.75 material as this is equal to 2.25 yards which is half of 4.5 yards equal to 90 flags.

To find 4.5 we have 3 pieces of material to begin with for part a and part b

This shows 1.5 x 3 = 4.5 yards

To find 2.25 we have 3 pieces of material in part c.

This shows 0.75 x 3 = 2.25 yards
