Answers

Answer:

Step-by-step explanation:

Mr. And Mrs. Jenkins wanted to make a down payment of $25,000 on a house. If the house costs $125,000, what percent is this?

The Percentage of the down payment is given as:

Down payment/Cost of the house × 100

Down payment = $25,000

Cost of the house = $125,000

$25,000/$125,000 × 100

= 20%

The percentage is 20%

Square root of 13^2 - 12^2 = 5

Answer:

B. 5

Step-by-step explanation:

Use the pythagorean theorem to solve: [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex].

[tex]a^{2}[/tex]+[tex]12^{2}[/tex]=[tex]13^{2}[/tex]

[tex]a^{2}[/tex]+144=169

Subtract 144 from 169.

[tex]a^{2}[/tex]-144=169-144

[tex]a^{2}[/tex]=25

Square root to get a.

[tex]\sqrt{a}[/tex]=[tex]\sqrt{25}[/tex]

Two supplementary angles that are 4x and 5x what is the value of x

Answers

Answer:

x = 20

Step-by-step explanation:

4x + 5x = 9x

9x = 180 (supplementary angles add up to 180 degrees)

Divide 180/9 = 20

Answer:

x = 20.

Step-by-step explanation:

Supplementary angles sum to 180, so:

4x + 5x = 180

9x =  180

x = 20.

Answers

p and q are the numbers of pillows and quilts, respectively.
4p+5q = 57
9p+5q = 72

Subtract the second equation from the first equation.

4p+5q = 57
-9p-5q = -72
——————
-5p = -15

p = 3

4(3)+5q = 57
5q = 57-12 = 45
q = 9

A pillow costs $3. A quilt costs $9.

Sally is 4 years older than Brody. Evelyn is 3 times older than Brody. If Brody's age is represented by x, create an expression that represents the total age of all three people.
A.4x+4
B. 5x
C.5x+4
D.7x

Answers

Answer:

Its C. 5x +4

Step-by-step explanation:

The expression that represents the total age of all three people is f(x) = 5x + 4.

What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.

Given is that Sally who is 4 years older than Brody. Evelyn is 3 times older than Brody.

Assume that Brody's age is represented by [x]. Then, the age of Evelyn will be (3x) and the age of Sally would be (x + 4). The expression that represents the total age of all three people is -

f(x) = x + (x + 4) + 3x = 5x + 4

f(x) = 5x + 4

Therefore, the expression that represents the total age of all three people is f(x) = 5x + 4.

The segments in each figure are tangent to the circle at the points shown.
Find each length.

Answers

9514 1404 393

Answer:

  RS = RT = 2

Step-by-step explanation:

The two tangents from a point are the same length.

  RS = RT

  y = y^2/2

  y^2/2 -y = 0

  y(y/2 -1) = 0 . . . . factor out y

Values of y that make these factors zero are ...

  y = 0 . . . . . . . . true if points R, S, T are coincident on the circle

  y/2 -1 = 0   ⇒   y = 2

Then the segment lengths are ...

  RS = RT = 2

Of course, there are plenty of instances of wilful shirking, where a little effort can overcome the slackness of memory; but every teacher who is honest enough to reckon with himself knows he cannot give a sensible reason why things are to be taught which have so little to do with the childs life that to-morrow, or the day after examination, they will be forgotten; things which he himself could not remember were he not repeating them year in and year out, as a matter of his trade. And every teacher who has thought at all for himself about the essential nature of the young humanity he is dealing with, knows that six hours of daily herding and in-penning of young, active bodies and limbs, accompanied by the additional injunction that no feet are to be shuffled, no whispers exchanged, and no paper wads thrown, is a frightful violation of all the laws of young life. Any gardener who should attempt to raise healthy, beautiful, and fruitful plants by outraging all those plants instinctive wants and searchings, would meet as his rewardsickly plants, ugly plants, sterile plants, dead plants. He will not do it; he will watch very carefully to see whether they like much sunlight, or considerable shade, whether they thrive on much water or get drowned in it, whether they like sandy soil, or fat mucky soil; the plant itself will indicate to him when he is doing the right thing. And every gardener will watch for indications with great anxiety. If he finds the plant revolts against his experiments, he will desist at once, and try something else; if he finds it thrives, he will emphasize the particular treatment so long as it seems beneficial. But what he will surely not do, will be to prepare a certain area of ground all just alike, with equal chances of sun and amount of moisture in every part, and then plant everything together without discrimination,mighty close together!saying beforehand, If plants dont want to thrive on this, they ought to want to; and if they are stubborn about it, they must be made to.In the second sentence of this paragraph, the repetition of the word things primarily serves to:A) qualify a claim by acknowledging an exception to itB) portray contrasting viewpoints as equally legitimateC) clarify an argument by restating it in simpler termsD) illustrate a generalization with a particular caseE) strengthen an assertion by broadening its implications simplify 4 to the 11th power over 4 to the -8th power (CH3CH2)2CHCH(CH3)2 Check all that apply.
