Question

What is the equation of the line that passes through the points (-1,2) and (6,3) in slope intercept form

Solution 1

$\bf \begin{array}{ccccccccc} &&x_1&&y_1&&x_2&&y_2\\ &&(~ -1 &,& 2~) &&(~ 6 &,& 3~) \end{array} \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{3-2}{6-(-1)}\implies \cfrac{3-2}{6+1}\implies \cfrac{1}{7} \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-2=\cfrac{1}{7}[x-(-1)]\implies y-2=\cfrac{1}{7}(x+1) \\\\\\ y-2=\cfrac{1}{7}x+\cfrac{1}{7}\implies y=\cfrac{1}{7}x+\cfrac{1}{7}+2\implies y=\cfrac{1}{7}x+\cfrac{15}{7}$

Question

A square poster has a side length of 26 in. Drawn on the poster are four identical triangles. Each triangle has a base of 8 in. and a height of 8 in. Children play a game in which they each wear a blindfold and throw a dart at the poster. A player whose dart lands inside a triangle wins a prize. Assuming that a player's dart will always land on the poster, what is the probability of the dart landing in a triangle? Enter your answer, as a decimal rounded to the nearest hundredth, in the box. P(a point on a triangle) =

Solution 1

$Probbility=\frac{desired}{total}$
$P_{triangle}=\frac{Area_{triangle}}{Area_{total}}$
$P_{triangle}=\frac{4\times\frac{b \times h}{2}}{s^{2}}$
$P_{triangle}=\frac{4\times\frac{8 \times 8}{2}}{26^{2}}$
$P_{triangle}=\frac{4\times\frac{64}{2}}{676}$
$P_{triangle}=\frac{128}{676}$
$P_{triangle}=0.189349112$
$P_{triangle=0.19$
$P_{triangle}\approx19\%$

Question

Which of the following is not an appropriate unit for acceleration? A.kg/s2 B.mi/hr2 C.m/min/sec D.cm/sec2

Solution 1

Which of the following is not an appropriate unit for acceleration?

kg/s2mi/hr2m/min/seccm/sec2

answer- kg/s2

Solution 2

Answer:

A.kg/s²

Step-by-step explanation:

A kilogram, or kg, is a measure of mass. This would not be a good unit for acceleration; acceleration is a measure of how far something goes in a given amount of time. It is a measure of distance over time, not mass over time.

Question

Tripp and Rico are two dogs. Tripp weighs exactly 35 pounds more than Rico. Together, they weigh exactly 49 pounds. How much does each dog weigh? Please use Two-step equations!!!! plz, help!

Solution 1

Using a system of equations, it is found that Tripp weighs 42 pounds and Rico weighs 7 pounds.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are given as follows:

Variable x: Tripp's weight.

Variable y: Rico's weight.

Tripp weighs exactly 35 pounds more than Rico, hence:

x = 35 + y.

Together, they weigh exactly 49 pounds, hence:

x + y = 49

35 + y + y = 49

2y = 14 -> y = 7

x = 35 + y -> x = 42

Hence, Tripp weighs 42 pounds and Rico weighs 7 pounds.

Solution 2

Call the weights of the two dogs $t$ and $r$ .

We know that Tripp weights 35lbs more than Rico, or:
$t=r+35$

We also know that the total weight of both dogs is 49lbs.:
$t+r=49$

Now, by substitution:
$(r+35)+r=49$
$2r+35=49$
$2r+35-35=49-35$
$2r=14$
$r=\frac{14}{2}$
$r=7$
Rico weighs 7lbs.

Then:
$t=r+35$
$t=7+35$
$t=42$
Tripp weighs 42lbs.

To check our work:
$t+r=49$
$42+7=49$
$49=49$ CHECK!
