solve for the width in the formula for the area of a triangle
Answer: [tex]\frac{2A}{h} = w[/tex]
Step-by-step explanation:
The formula for area of a triangle is [tex]A = wh\frac{1}{2}[/tex]
Now we have to isolate for w.
First multiply by the 2 which is the reciprocal of 1/2 to cancel it out.
[tex]2A = wh\\[/tex]
Now divide by h to isolate w.
[tex]\frac{2A}{h} = w[/tex]
Line CD passes through points C(3, -5) and D(6, 0) . what is the equation of the line CD in standard form?
Answer:
Option 2: 5x - 3y = 30
Step-by-step explanation:
Step 1: Find slope
(0-(-5))/(6-3) = 5/3
Step 2: Find b
y = 5/3x + b
0 = 5/3(6) + b
b = -10
Step 3: Write in slope-intercept form
y = 5/3x - 10
Step 4: Move x over
-5/3x + y = -10
Step 5: Multiply by -3 on both sides
5x - 3y = 30
And we have our final answer!

Five times a number which is 3 more than h. Write this as an expression.
｡☆✼★ ━━━━━━━━━━━━━━ ☾
So, let's start off with h
The expression needs to be '3 more than h'
This can be written as:
h + 3
The expression also needs to be 'five times' this value
This can be written as:
5(h + 3)
That would be your answer ^^

Sarkis wants to draw a triangle with sides measuring 4 ft, 10 ft, and 16 ft. Which is true about Sarkis’s plan? Sarkis cannot draw a triangle with these side lengths. Sarkis can only draw one unique triangle with these side lengths. Sarkis can draw exactly two triangles with these side lengths. Sarkis can draw more than one triangle with these side lengths.
Answer:
SHE CANNOT pls mark brainleist
Step-by-step explanation:
If you use the Triangle Inequality Theorem, you will find that 4+10 equals 14, which is less than 16. It has to be greater than 16 to be a triangle.
Sarkis cannot draw a triangle with these side lengths. Therefore, option A is correct.
Given that, a triangle with sides measuring 4 ft, 10 ft, and 16 ft.
What are the conditions to construct a triangle?In the triangle, the sum of any two sides is always greater than the third side. The difference between any two sides of the triangle is always less than the third side.
Sarkis cannot draw a triangle with these side lengths. Therefore, option A is correct.

Ok so the mean is the average of all the data. So we add up all the numbers, then divide that by the quantity of numbers.
For week one, thats 48,52,52,53,60,63,65 which equals 393, then we divide that by 7, and get 56.142857142857, so we round that to 56.1
Week 2 is 54,55,56,59,60,62,63 which is 409 divided by 7, and thats 58.428571428571 rounded is 58.4

In the Soft Boulder Cafe each table has 3 legs, each chair has 4 legs and all the customers and the three members of staff have two legs each. There are four chairs at each table. At a certain time, three-quarters of the chairs are occupied by customers and there are 206 legs altogether in the cafe. How many chairs does the cafe have?
Answer:
32 chairs
Step-by-step explanation:
In the soft Boulder cafe they a chairs , table and customers and the 3 members staffs.
Each Table = 3 legs
Each Chairs = 4 legs
Each customer = 2 legs
Each members of staffs = 2 legs
4 chairs goes with each table. This means 4 × 4 = 16 legs of chairs for each 3 legs of table.
At a certain time 3/4 of the chairs are occupied by customers. That is 3 out of 4 chairs are occupied plus 6 tables . Therefore,
3 + 16 + 6 = 25 legs of table
206 legs altogether - the 6 legs of the staff(3 staffs has 6 legs)= 200 legs
This means 200 legs = 8 tables. Therefore,
8 tables requires 32 chairs

Triangle XYZ is shown, where n ≥ 5. Triangle X Y Z is shown. The length of side X Y is n + 4, the length of side Y Z is 2 n, and the length of side Z X is n minus 2.
Answer:
The longest side of the triangle is YZ, the shortest side is ZX, the largest angle is ∠X and the smallest angle is ∠Y.
Step-by-step explanation:
The lengths of the sides of the triangle XYZ are as follows:
XY = n + 4
YZ = 2n
ZX = n - 2
According to the triangle inequality theorem, the sum of two sides of a triangle is always greater than the third side.
Then,
XY < YZ + ZX ⇒ n + 4 < 2n + n - 2 ⇒ n + 4 < 3n - 2 ⇒ 2n > 6 ⇒ n > 3
YZ < XY + ZX ⇒ 2n < n + 4 + n - 2 ⇒ 2n < 2n + 2 ⇒ 0 < 2
ZX < XY + YZ ⇒ n - 2 < n + 4 + 2n ⇒ n - 2 < 3n + 4 ⇒ 2n > -6 ⇒ n > -3
It is provided that n ≥ 5.
Then the sides of the triangle are:
XY = n + 4 ≥ 5 + 4 = 9
YZ = 2n ≥ 2 × 5 = 10
ZX = n - 2 ≥ 5 - 2 = 3
So, the longest side of the triangle is YZ. And the shortest side is ZX.
The largest angle of a triangle is opposite to the longest side.
The angle opposite to YZ would be X. So, the largest angle is ∠X.
The smallest angle of a triangle is opposite to the shortest side.
The angle opposite to ZX would be Y. So, the smallest angle is ∠Y.
Thus, the longest side of the triangle is YZ, the shortest side is ZX, the largest angle is ∠X and the smallest angle is ∠Y.

The pictures are in order - first being dwayne's and second being ivor's Dwayne Pipes uses this formula to work out the cost of a plumbing job in pounds.
Ivor Wrench uses this formula to work out the cost of a plumbing job in pounds. A job of x hours costs the same with Dwayne and Ivor.
Set up and solve an equation to work out x .
X=.........
The solution is: x = 10/3 hours
What is the equations with one variable?
An equation with one variable is a mathematical statement that involves an unknown quantity represented by a letter, usually x, and an equal sign, where the expressions on both sides of the equal sign have the same value.
We need to set up an equation using the given information to solve for x.
Let's start with Dwayne's formula:
Cost = 30x + 50
And Ivor's formula:
Cost = 45x
Since a job of x hours costs the same for both Dwayne and Ivor, we can set their formulas equal to each other:
30x + 50 = 45x
Simplifying and solving for x:
50 = 15x
x = 50/15
x = 10/3 hours
Therefore, the solution is: x = 10/3 hours

Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long. A customer came in during the morning and bought 120 centimeters of the velvet. Another customer bought an additional 14 meters during the afternoon. How much crimson velvet does Malik's shop have left? Write the answer in centimeters.
The length of crimson velvet bolt which Malik's shop has left is 1680 centimeters.
Recall :
1 meter = 100 centimeters
Original Length of Bolt = 32 meters = (32 × 100) = 3200 centimeters
Total length of bolt purchased :
Morning purchase = 120 centimeters
Additional purchase = 14 meters = (14 × 100) = 1400 centimeters
Total length purchased = (120 + 1400) = 1520 centimeters
The length of crimson velvet bolt left :
(Original length - total length purchased)
(3200 - 1520) centimeters = 1680 centimeters
Hence, Malik's shop has 1680 centimeters of Crimson velvet bolt left

After school, Marcus ran 3.2km and Cindy ran 1.95km. Who ran farther ? How much father?
Answer:
Marcus; 1.25 km
Step-by-step explanation:
Marcus ran farther than Cindy because 3.2 km is greater than 1.95 km.
How much farther is:
3.2 - 1.95 = 1.25 km
He ran 1.25 km farther than Cindy.
The person who ran further is the person who ran more kilometers.
The person who ran more kilometers is Marcus which means that Marcus ran farther.
The distance he ran farther by is:
= Distance Marcus ran - Distance Cindy ran
= 3.2 - 1.95
= 1.25 km
In conclusion, Marcus ran farther by 1.25 km.
