Explanation:
A triangle equals 180°, and they gave us one length already, and it says the one arm of the triangle is equal to the other so we know that the third angle is going to be the same as the second angle.
180=90+(6x+3)+(6x+3)
Combine like terms
180=96+12x
Subtract 96 from both sides
84=12x
Divide 12 by both sides
7=x
Now check it,
90+(6*7+3)+(6*7+3)
90+(45)+(45) =180

Write the equation in slope-intercept form: x-4y=8
Answers
Answer:
y=1/4x-2
Step-by-step explanation:
slope intercept form is y=mx+b
your equation right now is in standard form: ax+by=c
equation: x-4y=8
what we want to do is isolate y on one side
subtract x from both sides
-4y=-x+8
divide by 4 on both sides
y=1/4x-2
Hope this helps! :)
Answer:
[tex]y = \frac{1}{4} x - 2[/tex]
Step-by-step explanation:
First thing to do is siolate the y variable. We do this by subtracting x from both sides of the equation in this particular equation.
[tex]x - 4y = 8 \\ - x \: \: \: - x \\ - 4y = - x + 8[/tex]
Now we change the -4y into just y using division. We have to divide boths sides by -4 to do so.
[tex] - 4y = - x + 8 \\ \div ( - 4) \: \: \div ( - 4) \\ y = \frac{1}{4}x - 2[/tex]
There it is in slope intercept form.

Answers
Answer: See explanation
Step-by-step explanation:
Antonio has $350 to spend on skis. sales tax is 6%. decide if each description of a price and discount, plus sales tax, represents a pair of skis that antonio can purchase with the money he has. choose yes or no for each description. a. 25% off $450 b. 20% off $385 c. $20 off $360 d. 15% off $360 e. $10 off $340.
The amount of money that Antonio can spend will be:
= $350 - (6% × $350)
= $350 - (0.06 × $350)
= $350 - $21
= $329
a. 25% off $450
= $450 - (25% × $450)
= $450 - (0.25 × $450)
= $450 - $112.50
= $337.50
No
b. 20% off $385
= $385 - (20% × $385)
= $385 - (0.2 × $385)
= $385 - $77
= $308
Yes
c. $20 off $360
= $360 - $20
= $340
No
d. 15% off $360
= $360 - (15% × $360)
= $360 - $54
= $306
Yes
e. $10 off $340
= $340 - $10
= $330
No.
Based on the $329 that Anthony has, he can make purchases on:
b. 20% off $385
d. 15% off $360

A computer technician charges a flat rate for home visits plus $ 55 per hour. The technician bills $190 for a 2-hour home visit to install a new hard drive. The equation y − 190 = 55(x − 2) gives the total amount y the technician charges for x hours of work.
The equation in slope-intercept form is y = 55x + 80.
What does the y-intercept in this equation represent?
a. the rate of change
b. the total cost
c. the flat rate

Answers
Answer:
y - 190 = 55(x - 2)....distribute thru the parenthesis
y - 190 = 55x - 110....now add 190 to both sides
y = 55x - 110 + 190..simplify

A communications company has developed three new designs for a cell phone. To evaluate consumer response, a sample of n = 120 college students is selected and each student is given all three phones to use for one week. At the end of the week, the students must identify which of the three designs they prefer. The distribution of preference is as follows: Design 1=54, Design 2=38, Design 3=28. Do the results indicate any significant preferences among the three designs?
Answers
Answer:
The answer is "Its results are not consistent with its three designs Yes. Its results show significant differences between both the three designs."
Step-by-step explanation:
Following are the distribution of preference:
[tex]Design 1 =54 \\\\ Design 2=38 \\\\\ Design 3=28 \\\\[/tex]
[tex]Design \ \ \ \ \ \ \ \ \ \ O_i \\ 1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 54 \\2 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 38\\3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 28 \\Total \ \ \ \ \ \ \ \ \ \ 120[/tex]
An expected frequency([tex]E_i[/tex]) has 40 Null hypotheses to take n=120.to each design:
The effects of the three designs are standardized
Inaccurate.
Hypothesis Alternative:
The effects of the three prototypes are not uniform
Degrees Of freedom [tex]=(n-1)=(3-1)=2[/tex]
[tex]H_o, x^2 \ test\ statistic \ \sum_i {\frac{(O_i -E_i)^2}{E_i}} \\[/tex]
[tex]= \frac{(54 -40)^2}{40}+\frac{(38-40)^2}{40} + \frac{(28-40)^2}{40}\\\\=49+0.1+3.6\\\\=8.6[/tex]
Chi-squared distribution critical value at [tex]\alpha = 0.05 (x^2 _{0.052})=5.99[/tex]
Since [tex]x^2, a[/tex] value [tex]> x^2 -[/tex]table of [tex]\alpha =0.05 =5.99[/tex]is determined.

What is half of 36 kg
Answers
half of 36 kg will be 18 kg
The half of the 36 kg is obtained by dividing the quantity by 2 and it is 18 kg.
The division is a mathematical operation that contains decoupling a quantity or number into equal proportions. It is the inverse operation of multiplication. In division, a number called the dividend is divided by another number called the divisor to get the quotient. When a number is not completely divisible by another number, then dividing the number leaves a single digit that cannot be divided further by that number, thus digit is known as the remainder.
Divide 36 kg by 2,
Half of 36 = [tex]\frac{36}{2} = 18[/tex].
Therefore, half of 36 kg is 18 kg.
