Answer 1

Answer:

x = 6.25

Step-by-step explanation:

Suppose y = 2x - 2.5. Find x when y = 10

this gives us the equation:

10 = 2x - 2.5

add 2.5 to both sides

2x = 12.5

divide both sides by 2

x = 6.25

The sum of the lengths of two opposite sides of the circumscribed quadrilateral is 12 cm, the length of a radius of the circle is 5 cm. Find the area of the quadrilateral

Answers

Answer:

60cm^2

Step-by-step explanation:

We assume that is a circumscribing quadrilateral, rather than one that is circumscribed. It is also called a "tangential quadrilateral" and its area is ...

K = sr

where s is the semi-perimeter, the sum of opposite sides, and r is the radius of the incircle.

K = (12 cm) (5cm) = 60 cm²

_____

A quadrilateral can only be tangential if pairs of opposite sides add to the same length. Hence the given sum is the semiperimeter.

On vacation, Jocelyn wants to have her hair braided in multiple braids to cover her head. It costs a flat rate of $3, plus $0.85 per braid. She had saved $32. How many braids can she get?

Answers

Answer:

34 Braids

Step-by-step explanation:

.85 per braid means 1 is 85 cents, 2 is $1.70 and so on. So normally you would just divide the total amount of money, so for instance if you had $2.55 you would be able to afford 3 braids, since 3 braids cost $2.55. in fact $2.56, $2.57 aaaaaaaaaaall the way up to $3.39 would be 3 braids, then $3.40 would be 4 braids.

Here though you first pay 3 dollars. so you need 3 first, then an extra 85 cents to get 1 braid. 2 braids is 3 dollars plus 1.70, 3 braids is 3 + 2.55 4 braids is 3 + 3.40 and so on.

So what you want to do is first take away that 3 dollars you need before the braids, then divide by .85. for instance $6.40 would get you 4 braids as I showed bcause 3 + 3.40 = 6.40. now 6.40 - 3 = 3.40 then 3.40 divided by .85 = 4

The problem says we start with$32, so lets do those steps. first 32 - 3 = 29. then 29 divided by .85 = 34.11. well it's not whole number so lets try something. 34 braids would be 3 + .85*34 = 31.90 and 35 braids would be 32.75 So 31.90, 31.91 aaaaaaaaall the way up to 32.74 would be 34 braids then 32.75 would be 35 braids. well, $32 is in that in between space, so it is 34 braids.

When I did 32 - 3 = 29. then 29 divided by .85 = 34.11 that 34.11 does actually tell us we wouldn't get to 35, I just wanted to make it very clear. so the answer is 34 braids.

solve for x:
(1/x) + (1/2x) = 18

Answers

Answer:

/sorry/

Step-by-step explanation:

How to solve your problem

(1)+(12⋅)=18

\frac{x}{(\frac{1}{x})}+(\frac{1}{2} \cdot x)=18

(x1)x+(21⋅x)=18

Solve

Combine multiplied terms into a single fraction

(1)+(12)=18

\frac{x}{(\frac{1}{x})}+(\frac{1}{2}x)=18

(x1)x+(21x)=18

(1)+(12)=18

\frac{x}{(\frac{1}{x})}+(\frac{1x}{2})=18

(x1)x+(21x)=18

Multiply by 1

Eliminate redundant parentheses

Solution

(1)+2=18

what is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

James earns $3,129 a month.

He is saving 1/3 of his income each month.

So, money will james be saving each month

= 3129 x 1/3

= 1043

Hence, $1043 money will james be saving each month.

Justin car can travel 75 miles using 3 gallons of gas. At this rate, how far, in miles, can Justin travel using 8 gallons of gas????

Answers

Answer:

Justin travels 211.83 miles on 8.2 gallons of gas.

Step-by-step explanation:

77.5 miles / 3.1 gallons = x miles / 8.2 gallons

Solve for x... multiply by 8.2 gallons on both sides (that cancels it on the right) side of the equation.

8.2 gallons *77.5 miles / 3.1 gallons = x

635.5/ 3.1 = x

211.83 miles = x

What would be the effect size associated with a single-sample t test

Answers

Answer:

-0.67

Step-by-step explanation:

Given that :

Population mean, μ = 4.7

Sample size, n = 68

Sample mean, M = 4.3

Sample standard deviation, s = 0.6

The effect size, d can be obtained using the relation :

d = (M - μ) / s

d = (4.3 - 4.7) / 0.6

d = - 0.4 / 0.6

d = - 0.66666

d = - 0.67

Hence, effect size associated with a single-sample t test is - 0.67
