What is 15/7 an mixed number

Answer:

1460

Step-by-step explanation:

rounding to the nearest ten, that is nearest to 1456 which would be 1460 (hope this helps! ) ♡

Answer:

1460

Step-by-step explanation:

Original number is 1 4 5 6

To round to the nearest ten, look at the digit in the 10's place and the digit immediately to the right of it

The digit in the tens place is 5

If the digit to the immediate right of this digit is 5 or greater, round the digit in the tens place up by one digit and set the immediate right digit to 0

So 5 rounds up to 6

The 6 to the immediate right(units place becomes 0)

1 4 5 6 rounded to nearest ten==> 1 4 6 0

Answer:

90 minutes or 1 hour 30 minutes

Step-by-step explanation:

Time taken to fill t is inversely proportional to number of pipes. We can express this as t ∝ \(\frac{1}{n}\) where n is the number of pipes

We can also write this as t = \(\frac{k}{n}\) where k is a constant

Using the data given 80 = \(\frac{k}{8}\)    (1)

For 6 pipes, if the time taken is T then  

\(T = \frac{k}{6}\)      (2)

Dividing (2) by (1) gives

\(\frac{T}{80} = \frac{k}{6}\) ÷ \(\frac{k}{8}\)

\(\frac{k}{6}\) ÷ \(\frac{k}{8} = \frac{k}{6} \frac{8}{k} = \frac{8}{6}\\\\\)

So  

\(\frac{T}{80} = \frac{8}{6}\\\\\)

T = \(80 \frac{8}{6}\)  (multiplying both sides by 80

And this computes to 90 minutes or 1 hour 30 minutes

Given

To find

Let the purchase value be P,

ATQ,

P -3 x 0.1P = Rs 43,740

P-0.3P = Rs 43,740

0.7P = Rs 43,740

P = Rs 43,740/0.7

P = Rs 62,486 (approx)

Hence, the purchase value of the machine would be Rs 62,486

The remaining material for sewing is 5/2 material.

Fractions are used to represent smaller pieces (or parts) of a whole.

Given that, Keith buys 3 yards of material to make a blanket. He trims off a total of 1/6 yard before he begins sewing.

1/6 of 3 = 3x1/6 = 1/2

The remaining material = 3-1/2

= 5/2

Hence, The remaining material for sewing is 5/2 material.

The volume of the circular cylinder be,

⇒ 62.8 mm³

Given that,

For a circular cylinder,

Height = 5 mm

Radius = 2 mm

Then we have to find the volume of this circular cylinder

Since we know that,

The right circular cylinder is a cylinder with circular bases that are parallel to each other. It's a three-dimensional form. The axis of the cylinder connects the centers of the cylinder's two bases.

This is the most frequent sort of cylinder encountered in daily life. The oblique cylinder, on the other hand, does not have parallel bases and resembles a skewed construction.

volume of circular cylinder = πr²h

Here we have,

r = 2 mm

h = 5 mm

Now put the values into the formula we get,

Volume = π x 2² x 5

             = 62.8 mm³

Answer:

6 doughnuts

Step-by-step explanation:

5.00-.30= 4.70

4.70/.70=6.71

Shirley can buy 6 doughnuts if she wants them all in one carryout box.

To determine the number of doughnuts Shirley can buy, we need to understand the concept of word problems.

What is Word Problems?

Word Problems in Mathematics involves the use of mathematical concepts and understanding in solving real-life cases.

From the parameters given:

Supposed Shirley has $5.00 to spend.

But, we are told he wants all of it in one carryout box. So, if he first buys 1 doughnut with its carryout box, she has spent $1, leaving her with $4.

Now, we need to divide the remaining $4 with the charges of doughnuts;

i.e.

= $4/$0.7

= 5 doughnuts with a remaining amount of $0.5

Now, the total amount of doughnuts bought is

= (1 + 5) doughnuts

= 6 doughnuts

Answer:

x = 0.39 or

x = -1.72

Step-by-step explanation:

The quadrateic formula is:

\(x = \frac{-b\pm\sqrt{b^2 - 4ac} }{2a}\)

eq: 3x² + 4x - 2

which is of the form ax² + bx + c = 0

The mean number of ice chests in a section is 46.75.

The mean is the average or the most common value in a collection of numbers. In statistics, it is a measure of central tendency along median and mode..

To find the mean number of ice chests in a section, we need to calculate the sum of the ice chests and then divide total number of sections sampled.

Sum of ice chests = 48 + 51 + 26 + 73 + 51 + 48 + 26 + 51

Sum of ice chests = 374

Mean number of ice chests will be:

= (Sum of ice chests) / (Total number of sections sampled)

= 374 / 8

It's a minimum, at (8, -3)

Step-by-step explanation:

Option 1: you unwrap the square , add like terms, and then recognize it's a parabola and find the coordinates of the vertex.

Or look at it as -3 + something ^2. It means you are adding something positive to -3, so the sum is greater or equal to -3, that is the definition of a minimum. At that point you find the minimum by setting that something equal to 0 (which gives you x = 8) and the value is -3 + 0 = -3

Answer:

The Ballwin Bears are taller on average, and the Aviston Aces have players whose heights are more consistent.

Step-by-step explanation:

for derby dragon;

mean height = 72 inches

standard deviation = 1.2 inches

for aviston aces:

mean height = 70.8

standard deviation = 0.7 inches

for balwin bears;

mean height = 73 inches

standard deviation = 1.0 inches

the mean height of aviston aces < mean height of derby < mean height of balwin bears

So on average the balwin bears are taller.

The standard deviation of derby dragon is > that of balwin bears > aviston aces.

So the more consistent height is that of aviston aces players.

Answer:

69°

Step-by-step explanation:

if CA and AT are congruentsides, this means that the angle of C and T must also be the same.

In order for a triangle to be a triangle, they must meet the angle of 180 degrees.

We know CAT is = to 42

So we subtract 42 from 180 = 138 degrees

we then divide 138 by 2 and we get 69

angles c + t are both 69 degrees

Answer:

69°

Step-by-step explanation:

The measure of angle A is given as 42 and the sum of interior angles in a triangle is equal to 180° we subtract 42 from 180 and divide the result with 2 because this is an Isosceles triangle since |AC| = |AT| m<C = m<T

(180 - 42) ÷ 2 = 69°

Step-by-step explanation:

opposite sides are equal in a parallelogram!

Answer:

5) x = 1, y = -3

6) x = -20, y = 2

7) infinite solutions

8) no solutions

Step-by-step explanation:

5)

y = 5x - 8

y = -6x + 3

5x - 8 = -6x + 3

11x = 11

x = 1

y = 5 - 8

y = -3

6)

2x + 10y = -20

-x + 4y = 28

2x = -20 - 10y

x = - 10 - 5y

-x = 28 - 4y

x = -28 + 4y

-10 - 5y  = -28 + 4y

-10 + 28 = 4y + 5y

18 = 9y

2 = y

2x + 20 = -20

2x = -40

x = -20
