Answer:

[tex]p = 0.3w[/tex]

Step-by-step explanation:

Given

[tex]w \to weight[/tex]

[tex]p \to price[/tex]

[tex](w,p) = (12,3.60)[/tex]

Required

The equation

First, we calculate the unit ratio (k)

This is calculated by dividing price by weight

[tex]k = p/w[/tex]

[tex]k = 3.60/12[/tex]

[tex]k = 0.3[/tex]

Recall that: [tex]k = p/w[/tex]

Make p the subject

[tex]p = kw[/tex]

Substitute [tex]k = 0.3[/tex]

[tex]p = 0.3w[/tex]

Answer:

Answer OPTION C

AT LEAST... means that she needs 80% and more

Meaning its must be equal to 80% or greater than 80%

Average has to do with Mean.

Her mean would have to be

The sum of the 3 last algebra tests plus the unknown one she's supposed to have to complete 80%

So

Thatll be

80+75+86 + x /(4) ≥ 80

241 + x/(4) ≥80

Option C

Answer:

Age of Sean = 15

Age of Ricki  = 10

[tex]Ratio \ of \ their \ age = 15 : 10 = 3 : 2[/tex]

[tex]Sum \ of \ the \ ratio = 5[/tex]

[tex]Let \ number\ of sweets \ be \ x[/tex]

[tex]Number \ of \ sweets \ Sean \ got = \frac{3}{5} * x\\\\48 = \frac{3}{5} * x\\\\x = \frac{48*5}{3} = 80[/tex]

[tex]Total \ number \ of \ sweets = 80\\Sean \ got \ 48\\Number \ of \ sweets \ Ricki \ got = 80 -48 = 32[/tex]

Ans : a) 3  : 2

       b) 32 sweets

       c) 80 sweets

Answer:

75

Step-by-step explanation:

We know that 80% of Andrew's (former) baseball card collection is 60. Thus, We divide 60 by 80% (equal to 0.8) to obtain [tex]\frac{60}{0.8}=75[/tex].

Answer:

In total there were 75 cards in Andrews collection.

Step-by-step explanation:

We know that 60 is 80% of the total amount of cards Andrew has. Therefore, all we have to do to find the total number of baseball cards is to divide 60 by 80 to find 1% and then multiply the result by 100 to get 100% (the total amount of cards). And so we get...

60 / 80 x 100 = 60 / 0.8 = 75

Hi there!

I believe your answer is:  

The square root of 5 ([tex]\sqrt{5}[/tex]) is irrational.

Here’s why:  

⸻⸻⸻⸻

Since the square root of 5 is not a perfect square, it would be irrational.

3.14 x 25 = 78.5

Answer:

9^3 is Natural, Whole, Integer, and Rational

7/4 is Rational

√3 is Irrational

0 is Whole, Integer, and Rational

Thinking Process:

Alright, to start, with 9^3, it equal 729. This is a natural, whole, integer, and rational number. It is a natural number because it follows the counting (1, 2, 3...etc). Because of this, it is also part of all of the other rational categories as well.

With the next one, 7/4, this equals 1.75. It is not a natural, whole, or integer number because it is a decimal. However, it is rational, because it is still definite.

Next, with √3, this equals 1.73205.... It is irrational because it is not definite as it is a sequence of numbers that go on forever, being unpredictable in nature.

Last is 0, it is not a natural number because it does not follow the counting (1, 3, 3...etc). But it is whole because it follows the counting (0, 1, 2, 3...etc). This is along with it being an integer and rational because of this.

Answer:

just use demos graphing calculator

Step-by-step explanation:

Answer:

1 ounces of water= $0.16

1 ounces of soda= $0.15

Water costs $0.16 per ounces while soda costs $0.15 per ounces which means soda costs less than water per ounces.

Answer:

Mean is greater

Step-by-step explanation:

For a skewed distribution, then the tail is longer to one side from the center than to the other. In a right skewed distribution, the tail is longer to the right.

When a distribution is skewed, the mean will be closer to the tail Than the median. Therefore. For a right skewed histogram, the mean is closer to the tail of the histogram and hence closer to the right. Once this happens, values closer to the right of a distribution are higher (number line). Thus the mean will be greater than the median.

Answer:

43.566 ft

Step-by-step explanation:

Straight sides: 2 long 1 short

2 x 10 + 8 = 28 ft

Curved side: Remember that the circumference of a circle is 2πr or πd.

Since this is a semicircle, divide the circumference you get by 2.

From the diagram: d = 8

total circumference = 8 x π = 8π

semicircle = 8π ÷ 2 = 4π ft

Total perimeter

= (28 + 4π) ft

= (28 + 12.566) ft (5sf)

= 43.566 ft (5sf)

The radius of the hemicircle is r = 8/2 cm = 4 cm.

So the perimeter of the hemicircle part is

[tex]\pi \times r \: = (22 \div 7) \times 4 = 12.57 \: cm[/tex]

The perimeter of the rectangular part = 10+10+8 = 28 cm.

So, the final answer is

[tex]28 \: cm + 12.57 \: cm = 40.57 \: cm[/tex]
