Answer:

463mi

Step-by-step explanation:

Answer:

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

16 / 20 = 0.800

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 800

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*

In this case, Rule I applies, so 16/20 (or 0.800) rounded to the nearest hundredth in decimal format is:

0.80

Next, we will make 16/20 rounded to the nearest hundredth in fraction format. Since you can divide our decimal format answer above by 1 and keep the same value, you can make it like this:

0.80 = 0.80/1

Then, we multiply the numerator and denominator by 100 to get rid of the decimal point:

(0.80 x 100) / (1 x 100) = 80/100

That's it. 16/20 rounded to the nearest hundredth is displayed below (simplified if necessary):

4/5

Answer:

I think maybe 7p+5q

Step-by-step explanation:

Given:

The scatter plot and trend line.

To find:

Type of association, slope, equation of trend line and average cost of apple per pound.

Solution:

Form the given graph it is clear that the trend line passes through the two points (0,0) and (12,24).

Slope of trend line is

[tex]m=\dfrac{24-0}{12-0}[/tex]

[tex]m=\dfrac{24}{12}[/tex]

[tex]m=2[/tex]

Slope of trend line is positive. It means, it represents positive correlation.

So, the type of association of the scatter plot is positive association.

Therefore, the slope of trend line is 2.

The trend line passes through (0,0) have slope 2, so the equation of the trend line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-0=2(x-0)[/tex]

[tex]y=2x[/tex]

Therefore, the equation of trend line is [tex]y=2x[/tex].

Slope of the line is 2.

Therefore, the average cost of apples per pound is $2.

Answer:

Step-by-step explanation:

The circumference for a circle is found in the formula

[tex]C=\pi d[/tex]

so if the diamteter is 7, then the circumference is

[tex]7\pi[/tex] or if you are told to round to the nearest hundredth or thousandth, multiply pi in as 3.1415 to get that the circumference is 21.9905 cm

Answer:Jada will get same shade as Perfect Purple Water

Step-by-step explanation:

STEP 1

To get the right  recipe for Perfect purple water, every new mixture must have an equivalent ratio as the ideal mixture

The ideal mixture is given as

8ml  blue water and 3 ml red water.

Step 2

Andre mixes 16ml blue water with 9ml red water

[tex]\frac{8ml}{3ml}[/tex] is not equivalent to [tex]\frac{16ml}{9ml}[/tex]

Because dividing Andre's mixture  by a common value  will  not give  the equivalent ratio of the ideal recipe

[tex]\frac{16ml}{9ml}[/tex]  [tex]\frac{/}{/}[/tex]  [tex]\frac{3}{3}[/tex] =[tex]\frac{5.3ml}{3ml}[/tex]  

Jada mixes 24ml blue water with 9ml red water

[tex]\frac{8ml}{3ml}[/tex] is equivalent to [tex]\frac{24ml}{9ml}[/tex]

Because dividing Jada's mixture  by a common value  gives the equivalent ratio of the ideal recipe

[tex]\frac{24ml}{9ml}[/tex]  [tex]\frac{/}{/}[/tex]  [tex]\frac{3}{3}[/tex] =[tex]\frac{8ml}{3ml}[/tex]  

This shows that Jada got the right recipe and will get  same shade as Perfect Purple Water but in a higher quantity, 3 times the right recipe for  Perfect Purple Water

Step-by-step explanation:

because r is 1/2 of d so you would have 1 d instead of 2 r

Answer:

A and B

Step-by-step explanation:

Given

List of given options

Required

Which will correctly take 3 to fill the blank

Represent the blanks with x

Option A:

[tex]x : 4 = 12 : 16[/tex]

Convert to fractions

[tex]\frac{x}{4} = \frac{12}{16}[/tex]

Multiply through by 4

[tex]4 * \frac{x}{4} = 4 * \frac{12}{16}[/tex]

[tex]x = \frac{48}{16}[/tex]

[tex]x = 3[/tex]

Option B:

[tex]1 : 5= x : 15[/tex]

Convert to fraction;

[tex]\frac{1}{5} = \frac{x}{15}[/tex]

Multiply through by 15

[tex]15 * \frac{1}{5} = \frac{x}{15} * 15[/tex]

[tex]15 * \frac{1}{5} = x[/tex]

[tex]3 = x[/tex]

[tex]x = 3[/tex]

Option C:

[tex]x : 1 = 12 : 3[/tex]

Convert to fraction

[tex]\frac{x}{1} = \frac{12}{3}[/tex]

[tex]x = 4[/tex]

Option D

[tex]15:x = 3:1[/tex]

Convert to fraction

[tex]\frac{15}{x} = \frac{3}{1}[/tex]

Cross Multiply

[tex]3 * x = 15 * 1[/tex]

[tex]3 * x = 15[/tex]

Divide through by 3

[tex]x = 5[/tex]

From the above calculations.

Option A and B can be filled with 3

Answer:

Answer:

35, 35, and 50

Step-by-step explanation:

50 + x + x = n

n ÷ 3 = 40

n = 40 x 3

n = 120

50 + 2x = n

50 + 2x = 120

2x = 120 - 50

2x = 70

2x/2 = 70/2

x = 35

To check:

35 + 35 + 50 = 120

120 ÷ 3 = 40

Hope this helps

Answer:

35

Step-by-step explanation:

let us take each boy's weight as x

therefore,

average = [tex]\frac{x+x+50}{3\\}[/tex]

40 = [tex]\frac{x+x+50}{3\\}[/tex]

40 x 3 = x + x + 50

120 - 50 = 2x

70 = 2x

2x = 70

x = [tex]\frac{70}{2}[/tex]

x = 35

So weight of each boys is 35.

Solving, we get x + 20 = 29, x = 9.

Answer:

9 cm

Step-by-step explanation:

The perimeter of a polygon is the sum of the lengths of all the sides of the polygon.

If a polygon is a triangle, and its 3 sides have length a, b, and c, then the perimeter is the sum of a, b,, and c.

perimeter = a + b + c

Here, the perimeter = 29 cm

The lengths of the sides are a = 8 cm, b = 12 cm, c = x.

8 + 12 + x = 29

x + 20 = 29

x = 9

Answer: 9 cm

Answer:

32%

Step-by-step explanation:

Answer:

y = 17(7) + 6

Step-by-step explanation:

Given that:

Amount owed = $125

Payment per week = $7

Number of whole weeks to pay :

$125 / $7 = 17.85 = 17 whole weeks

$125 - (17 * 7) = $125 - $119 = $6

Using slope intercept notation :

y = mx + c

Where m = slope ; c = intercept. ;

m = 17,; x = $7, c = $6

y = 17(7) + 6

Saving amount at the end of 2 years:

Answer:

5.38 ounces

Step-by-step explanation:

Given that :

Alice height = 1 mile

Distance of earth to moon = 239000 miles

Number of base 10 cakes required so they Alice's head just touches the moon ;

Using the relation :

Distance = height per ounce * 10^number of ounces

Height per ounce = 1 mile ;

Let number of ounces = n

Hence,

239000 = 1 * 10^n

239000 = 10^n

Take log of both sides

Log(239000) = n

5.3783979 = n

5.3784 = n

Hence, Alice should take 5.38 ounces of base 10 cakes

Answer:

ab+bc+ca=0

Step-by-step explanation:

We are given:

[tex]x^a=y^b=z^c[/tex]

xyz=1

Separating equations:

[tex]x^a=z^c[/tex]

[tex]y^b=z^c[/tex]

Solving the first equation for x:

[tex]\displaystyle x=z^\frac{c}{a}[/tex]

Solving the second equation for y:

[tex]\displaystyle y=z^\frac{c}{b}[/tex]

Substituting in

xyz=1:

[tex]\displaystyle z^\frac{c}{a}z^\frac{c}{b}z=1[/tex]

Adding the exponents:

[tex]\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=1[/tex]

Since [tex]1=z^0[/tex]:

[tex]\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=z^0[/tex]

The base is z on both sides so we get rid of them:

[tex]\displaystyle \frac{c}{a}+\frac{c}{b}+1=0[/tex]

Multiplying by ab:

bc+ac+ab=0

Reordering:

ab+bc+ca=0

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. Rectangle: This is because all the angles are at right angles and the length is more than the breadth.

Area = Length X breadth = 6m X 5.1 m =30.6 metre square

2. Kite: it has two equal pairs of sides adjacent to each other

Area =(BD X CE )/2 = (8 X 12) /2 = 48

3. Parallelogram: This is because it has two opposite sides that are parallel, and the angles are not 90 degrees.

Area = base X height = 5.7 X 8 = 45.6 metres square

4. Rectangle: This is because all the angles are at right angles and the length is more than the breadth.

Area = Length X breadth = 2 yd X 3.1 yd = 6.2 square yards

5. Trapezium: it has only one pair of sides parallel.

Area = 0.5 ( top side + bottom side ) X height = 0.5 (6+3 X 5) = 22.5

6. Kite: it has two equal pairs of sides adjacent to each other

Area =(EG X FH)/2 = (10 X 7) /2 = 35
