Write an equation of the line that passes through the given point and has the given slope.
(1,-5); slope -3/2
Answer:
y – y 1 = m ( x – x 1 ) m = your slope ( x 1 , y 1 ) = your point y – ( − 5 ) = − 3 2 ( x – 1 ) y + 5 = − 3 2 ( x – 1 ) Now we need to do a little algebra to get the equation in standard form: A x + B y = C , where A, B and C are relatively prime integers. y + 5 = − 3 2 x + 3 2 3 2 x + y = 3 2 − 5 now let's multiply through with 2 to get rid if the fractions: 2 ( 3 2 x + y = 3 2 − 5 ) 3 x + 2 y = 3 − 10 3 x + 2 y = 7
Step-by-step explanation:
Find x. Round to the correct number of decimal places.
Step-by-step explanation:
Using Trigonometry,
Let the height be AD, angle containing 90° be B and the angle containing 65° be C, respectively.
cos 30° = AD/40
AD= 40√3/2 = 20√3.
<DAC = 25°.
cos 25° = AD/AC
0.90 = 20√3/AC
AC = 38.49. is the value of x.

Answer:
The Noble gases are the least reactive of any elements on the periodic table.
Explanation:
All of the elements in Group Zero are noble gases. The list includes helium, neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They are also called inert gases because they do not react with other elements of periodic table. The reason behind their inertness is that their outermost shell is complete and they do not have the tendency to lose or gain electrons.
Answer:
The Halogens form acidic compounds with hydrogen
Explanation:
The non metals in group 7 of the periodic table are known as the halogens. When they react wit hydrogen their respective acid is formed For example, hydrogen chloride (HCl)is produced when hydrogen combines with Chlorine and in the same way Hydrogen Bromide is produced when Bromine reacts with hydrogen.
Answer:
The halogens are the most reactive among all the non metals
Explanation:
The non-metal elements in Group 7 are known as the halogens which consist of five chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They get less reactive as we go down the group. This is the opposite trend to that seen in the alkali metals in Group 1 of the periodic table which are reactive among metals.

If varies directly as y and y = 15 when = 25. If = 155 then y is
Answer:
y = 93
Step-by-step explanation:
I assume the other variable is x.
"If x varies directly as y and y = 15 when x = 25. If x = 155 then y is"
Direct variation:
x = ky
25 = k * 15
k = 25/15
k = 5/3
The direct variation equation is
x = (5/3)y
155 = (5/3)y
y = 155 * 3/5
y = 93

Make a tree diagram to show all the possible sequences of answers for six multiple-choice questions, each with three possible responses. Assuming that you are guessing the answers so that all outcomes listed in the tree are equally likely, what is the probability that you will guess the one sequence that contains all six correct answers? (Round your answer to five decimal places.)
Answer:
Steps and solution in the attached picture.
Step-by-step explanation:
Steps and solution in the attached picture.
Based on the information given, the probability that all three are correct will be 0.0000217.
How to calculate the probabilityFrom the information given, there are six multiple-choice questions, each with three possible responses.
If an individual is guessing the answers so that all outcomes listed in the tree are equally likely, the probability that the person will guess the one sequence that contains all six correct answers will be:
A = correct answer = 1/6
B = incorrect answer = 1 - 1/6 = 5/6
The probability of guessing the correct answer will be:
= 1/6 × 1/6 × 1/6 × 1/6 × 1/6 × 1/6
= 0.0000217

Solve for y
13.5
12
9
10.5
Answer:
y = 9
Step-by-step explanation:
1. We know that the line the angles fall on is a straight angle, meaning it's worth 180°.
2. Given the information above, 8y + 96 + 12 = 180.
3. (Solving equation above).
Step 1: Simplify both sides of the equation.
[tex](8y)+(96+12)=180[/tex] [tex]8y + 108=180[/tex]Step 2: Subtract 108 from both sides.
[tex]8y + 108 - 108 = 180 - 108[/tex] [tex]8y = 72[/tex]Step 3: Divide both sides by 8.
[tex]\frac{8y}{8}=\frac{72}{8}[/tex] [tex]y = 9[/tex]Step 4: Check if solution is correct.
[tex]8(9)+96+12=180[/tex] [tex]72+96+12=180[/tex] [tex]168+12=180[/tex] [tex]180=180[/tex]Therefore, y = 9.
Mrs. Neville is baking 5 batches of cookies. She will need 2 1/3 cups of flour for each
batch of cookies. If she begins with a bag of flour that contains 20 cups, how many cups
of flour will be left in the bag? (Show work on your paper)
Answer:
8.33 cups of flour
Step-by-step explanation:
In order to find the answer to this question you need to multiply the amount of batches by the amount of flour it takes to make that batch and then just simply make sure the answer is a mixed number.
[tex]2\frac{1}{3} \times5[/tex]
Convert the mixed number into a improper fraction:
[tex]2\frac{1}{3} =2\times3=6+1=\frac{7}{3}[/tex]
[tex]\frac{7}{3} \times5[/tex]
Remember that all whole numbers have a invisible denominator:
[tex]5=\frac{5}{1}[/tex]
[tex]\frac{7}{3} \times\frac{5}{1}[/tex]
Multiply:
[tex]7\times5=35[/tex]
[tex]3\times1=3[/tex]
Now subtract from 20 cups:
[tex]\frac{20}{1} -\frac{35}{3}[/tex]
Find the common denominator
CD = 3
20 1 - 35 3 = (20 × 3) + (35 × 1) 1 × 3 = 60 - 35 3 = 25 3 = 8.33
[tex]=8.33[/tex]
Hope this helps.

Write root 3 x root 6 in the form b root 2 where b is an integer.
3 root 2
root 3 x root 6 = root 18
to write it in its simplest form, we have to reduce the number to a situation, where we have a product that includes a perfect square and and another number
let me break that down
let us use another example;
root 8
we think of the largest perfect square that is also a factor of 8
then, we conclude to our answer; 4
next, we think of the number that multiplies with 4 to give is 8 and that is 2
so, we bring the 4 outside by square rooting it and everything gives us
2 root 2
to open this, we just square the 2 outside and multiply it by the 2 inside to give us root 8
if we apply this example to our question,
root 18 = root 9 * 2
this is because 9 is the largest square and factor of 18 and 2 multiplies with 9 which gives us root 9 * 2
then, we square root 9 to give us 3 and we bring this 3 out to give us
3 root 2
hope this helps.

Donna is going to swim 19 laps. She completed 12 laps what fraction of her swim remains?
Answer:
7/19 laps
Step-by-step explanation:
She has 19 total laps to do so you know that the denominator is 19.
She already completed 12 laps so that means she has 7 laps left out of the 19 total laps because 19-12= 7

Given: AD, What statements are true regarding the given statement and diagram? EB bisects LAEC IZCED is a right angle. ZCEA is a right angle. a mZCEA = 1 2 (mZCEB) C mZCEB = m_BEA B mZ DEB = 135° MZAEB = 35° A E
The option first, option second, option fourth, and option fifth are correct.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
We have:
AD
EB bisect angle AEC
From the figure:
Angle CED is a right-angle triangle
So,
Angle CEA is also a right-angle triangle
Angle CEB = Angle BEA = 90/2 = 45 degrees
Angle DEB = Angle CED + Angle CEB = 90 + 45 = 135 degrees
Thus, the option first, option second, option fourth, and option fifth are correct.

- x from both sides
5=7x-6
+ 6 to both sides
11=7x
÷ both sides by 7
11/7=x
What is the height of a triangle that has an area of 24 in.2 and a base with a length of 8 in.?
Answer:⬇️⬇️⬇️⬇️
Step-by-step explanation: Area of a triangle = ½base times height⇒ A = ½bh
Given that the area is 24 and the base is 8, we would have this equation
24 = ½(8)h
24 = 4h divide both sides by 4
6 = h So the height of the triangle is 6 feet
CHECK
A = ½bh
24 = ½(8)(6)
24 = 4(6)
24 = 24√
