Step-by-step explanation:

5/6+1/15+1/12in on minute

Emma's best record is 59/60 kilometers per minute.

Given that, Emma personal record was 5/6 of a kilometer in one minute.

To add fractions there are three simple steps:

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if possible)

Given, after six months, she improved her record by 1/15 of a kilometer. After a year, she further improved her record by 1/12 of a kilometer.

Now, 5/6 + 1/15 + 1/12

LCM of denominators 6, 15 and 12 is 60.

50/60 + 4/60 + 5/60

= 59/60

Therefore, Emma's best record is 59/60 kilometers per minute.

Answer:

The scale factor would be -5.

Step-by-step explanation:

If the driveway is 20 feet but 4 foot on the canvas. Then 20/4 is 5. But since the width is going from 20 to 4, the numbers are going down to it would be a negative scale factor. If it was going from 4 width to 20 width, the scale factor would be a positive 5.

Given:

Drawing a vowel from letter tiles that spell out MATHEMATICS.

Chances = [tex]\dfrac{?}{?}[/tex]

To find:

The correct values for the blanks.

Solution:

Vowels are a, e, i, o, u.

In MATHEMATICS, the vowels are A, E, A, I.

Number of vowels = 4

We know that,

[tex]Probability=\dfrac{\text{Number of selected vowels}}{\text{Total number of vowels}}[/tex]

[tex]Probability=\dfrac{1}{4}[/tex]

So, the chance of drawing a vowel from letter tiles that spell out MATHEMATICS is [tex]\dfrac{1}{4}[/tex].

Blank 1: 1

Blank 2: 4

Therefore, the value for blank 1 is 1 and the value for blank 2 is 4.

Answer:

B

Step-by-step explanation:

Hi,

2πr is the formula for circumference, you know your diameter is 4cm and radius is half of the diameter, so your radius is 2cm.

To find the circumference, you have to multiply 2 by 2 and pie. 2 x 2 is 4. So 4 times pie. B is your correct answer.

I hope this helps :)

Answer:

x is 20

Step-by-step explanation:

Answer:

A. -8

Step-by-step explanation:

Given the values of the function in a table, to determine the initial value of the function, you need to determine where x = 0.

Since the function is linear, the rate of change will be constant/the same.

To find the rate of change, you need to divide the change in the y value by the change in the x value.

X Y

+2↓ -5 | 7 ↓ -6

+2↓ -3 | 1 ↓ -6

+2↓ -1 | -5 ↓ -6

1 | -11

_____________

Since y changes by -6 and x changes by +2 every time, ∆Y/∆X = -6/+2 [Reduce] = -3/+1.

Slope = -3.

This means that y will decrease by 3 units every increase of 1 unit in x.

If (-1, -5) is a point which means that -1 is x when -5 is y.

We can apply the rate of change to see where x = 0.

So -5 + 1(-3/+1) → -5 + -3 = -8

Answer:

$0.18

Step-by-step explanation:

Given that :

Number of bananas purchased = 8

Cost at which the 8 bananas were purchased = $1.44

The unit price of bananas can be obtained using the relation :

Total Cost of bananas / number of bananas

Unit price = $1.44 / 8

Unit price = $0.18

Price per unit of banana = $0.18

The given expression is:

[tex]\dfrac{3.6\times 10^7}{7.2\times 10^7}[/tex]

To find:

The value of the quotient.

Solution:

We have,

[tex]\dfrac{3.6\times 10^7}{7.2\times 10^7}[/tex]

It can written as:

[tex]=\dfrac{3.6}{7.2}\times \dfrac{10^7}{10^7}[/tex]

[tex]=\dfrac{1}{2}\times 1[/tex]

[tex]=0.5[/tex]

It can be rewritten as:

[tex]=5\times \dfrac{1}{10}[/tex]

[tex]=5\times 10^{-1}[/tex]

Therefore, the value of the quotient is [tex]5\times 10^{-1}[/tex].
