Answer:

y = 2

Step-by-step explanation:

varies inversely

xy = k

y = 7 when x = 2/3

(2/3)7 = k

14/3 = k

k = 14/3

--------------------

find y when x = 7/3

(7/3)y = 14/3

multiply both sides by 3/7

y = 14/3 * 3/7

y = 2

Answer: y = 2

Step-by-step explanation: When we have two sets of inversely related coordinates, x₁ and y₁, and x₂ and y₂, we can use the product rule, shown below, to find the missing value.

Since we know that y = 7 when x = 2/3, one set of coordinates will be 7 and 2/3 and since we want to find the value of y when x = 7/3, our other coordinates will be 7/3 and y.

(2/3)(7) = (7/3)(y)

So we have 14/3 = 7/3y and solving for y from here, we find that y = 2.

Answer:

13) 25 and 17

14) cupcakes = $5

brownies = $3

Step-by-step explanation:

13)  you can set this up as equations

so x + y = 42

x-y = 8

solve simultaneously by subtracting from each other

2y = 34

y= 17

if y = 17

42 - 17 = 25 = x

14) set up as equations again

Ben    7c + 10b = 65

franklin   7c +7b = 56

subtract from eachother

3b = 9

b = $3

7c + 10(3) = 65

7c = 35

c = $5

Answer:

First question = 2&8

Second question = Cupcakes 6.5 Brownies 8

Answer:

Area = 1384.7 square miles

Step-by-step explanation:

[tex]Area = \pi r^2 = 3.14 \times 21^2 = 3.14 \times 21 \times 21 = 1384.74 = 1384.7 \ mi^2[/tex]

Answer:

1, 385.4 mi

Step-by-step explanation:

A = pi(r^2)

A = 3.14 x 21^2

A = 1385.44 mi

Answer: Sum is  51360

Step-by-step explanation: I have heard same legend and it is also told in hih school math books.

There are 160 pairs numbers which sum is 321, also (320 +1) + (319+2) + ... + (160 + 161).    So sum is  160·321

Answer:

the sum of all three angles is 180° in every plane triangle.

knowing that we know that the upper right angle is 180-99-37 = 44

do it follows:

-x-5 = 44

and

-x = 49

and there

x is -49

Answer:

a. The title of a randomly selected individual's favorite book --> Nominal

b. The height of a randomly selected semi tractor and trailer on I 70 --> Ratio

c. Placement (1st, 2nd, etc.) within a video game tournament --> Ordinal

d. The temperature in Paris, France at noon --> Interval

Step-by-step explanation:

Required

The level of measurement of each

The question was submitted along with the (correct) answers; So, I will provide the explanations

(a) When data are measured using tags and labels; the level of measurement is Nominal

In (a), the data are measured using titles; this represents nominal level

(b) When data are measured using differences or intervals; the level of measurement is Ratio.

In (b), the data are represented using ratio such as 1 - 70 (i.e. 1 to 70); this represents ratio level

(c) When data are measured using orders such as first, second, etc.; the level of measurement is Ordinal

In (c), the data are categorized using 1st, 2nd, etc...; this represents ordinal level

(d) When data are measured using interpretable and meaningful intervals; the level of measurement is Interval;

In (d), the data are categorized using temperature at a certain interval; this represents interval level

Answer:

10

Step-by-step explanation:

( 1 / 20 ) x ( 1 / 8 ) x 1600

= ( 1 / 20 x 8 ) x 1600

= ( 1 / 160 ) x 1600

= 1600 / 160

Answer:10

Step-by-step explanation:

1/20 x 1/8 x 1600 = 10

= 10

Answer:

Kevin eats 1 pie for every 33 seconds that pass

Step-by-step explanation:

A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.

If we were wondering how many seconds Kevin takes to eat a pie then the equation would look like:

132 seconds / 4 pies = 33 seconds per pie

33 seconds / 1 pie

However, if we were looking for how many pies Kevin eats in a second, then the equation would look like:

4 pies / 132 = .0303 or 3.03% of a pie per second

.0303 pies / 1 second

Answer:

The number of plans that cost between $52.38 and $96.7 is 913.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean of $74.54, standard deviation of $11.08

Percentage of plans that cost between $52.38 and $96.7.

52.38 = 74.54 - 2*11.08

96.7 = 74.54 + 2*11.08

Within 2 standard deviations of the mean, so by the Empirical Rule, 95%.

The number of plans that cost between $52.38 and $96.7 is .

95% of 961. So

0.95*961 = 913

The number of plans that cost between $52.38 and $96.7 is 913.

Answer: 50,380m

Step-by-step explanation:

190m * 270m = 51,300m

23m * 40m = 920m

Because the barn is in the field, we subtract the barn's area from the field's area, which leaves us with

51,300m - 920m = 50,380m

Answer:

104°

Step-by-step explanation:

[tex]\frac{sin~B}{18} =\frac{sin~29}{9} \\sin~B=\frac{18}{9} \times sin~29\\sin~B=2~sin~29\\B=sin^{-1}(2 ~sin~29)\\=104^\circ[/tex]

Answer:

[tex]a=-\frac{2}{3}[/tex]

Step-by-step explanation:

We are given the lines, [tex]y=3x+8[/tex] and [tex]2y=ax-5[/tex]. For the latter equation, we can isolate the variable y to have the same format as the first. We want to create a y=mx+b equation where m represents the slope of the line. We now have the equations:

[tex]y=3x+8[/tex] and

[tex]y=\frac{a}{2}x-2.5[/tex]

The definition of perpendicular lines is that their slopes must be the negative reciprocal of each other. Thus:

[tex]-\frac{1}{3}=\frac{a}{2} \\\\a=-\frac{2}{3}[/tex]

Answer:

Step-by-step explanation:

For the GCF to be 6, terms of the polynomial must be multiples of 6, but must have no other common factors. A simple polynomial that meets this requirements is ...

  6a +12b

One equivalent form can be had by factoring 6 from the terms:

  6(a +2b)

Since 6 has a factorization of its own, another equivalent form can be had by factoring out one of the factors of 6. The ones of interest are 2 and 3, so we can write ...

  2(3a +6b)

or ...

  3(2a +4b)
