Three-twelfths of the girls on Jamilia’s softball team missed practice. Which of the following is equal is equal to 3/12?
if ABC is similar to DEF, determine the measure of A
Answer:
the answer is 66°
Step-by-step explanation:
As it is given that triangle ABC is similar to triangle DEF so
< A = < D ( being corresponding angles of similar triangles)
3x + 18° = 4x + 2°
4x - 3x = 18° - 2°
x = 16°
So now
< A = 3 * 16° + 18° = 66°
5. Write an equation that models exponential decay.
Answer:
Step-by-step explanation:
y = ab^x where 0<b<1 for exponential decay
an example would be y = 3(1/7)^x
The area of a rectangle is 35x - 20. Find the length and width of the triangle. (Hint: Factor completely) Write your answer as a product. Ex: 8(3x-2).

Make a triangle to find c, the hypotenuse.
Using the Pythagorean Theorem:
a^2+b^2=c^2
4^2+6^2=c^2
16+36=c^2
52=c^2
7.211102550927=c

what is x? (7x+1)=(9x-7)
Step-by-step explanation:
Given
7x + 1 = 9x - 7
9x - 7x = 1 + 7
2x = 8
x = 8 / 2
x = 4

Your mom is throwing a huge party for your graduation! Her total budget for the party is $1050. She must pay a fee of $400 to hold your party at Dave & Buster's. She is responsible for paying $50 for each guest so that they can eat and play. How many guests, g, can you invite to your graduation party?
Step-by-step explanation:
She has 1050
400 of that is the DB fee
Now she has 650 dollars
650/50 per person is 13
She can have 13 people

Find the area of the circle. Round your answer to the nearest hundredth.

What is the value of X
Answer:
11=x
Step-by-step explanation:
since the lines are parallel the distances between each section of line is proportional to each other.
5/6=(x-1)/12
multiply both sides by 12
12(5/6)=(x-1)12/12
10=(x-1)
add 1 to both sides
10+1=x-1+1
11=x

Answer:
Slope = 0
Step-by-step explanation:
Given the pair of points: (-3,2) (7,2)
Slope formula: y2-y1/x2-x1
2-2/7-(-3) = 0/10
0/10 = 0

What’s the value of x?
Answer:
6*15 = 5(x+5)
90 = 5x + 25
65 = 5x
x = 13
Step-by-step explanation:
I've gone ahead and labeled some points.
There is a formula that says PA*PB = PC*PD, this is what you use. If you would like me to show why this works I would be happy to.
So what we have is PA = 6, PB = 9+6 = 15, PC = 5 PD = 5+x so let;s writ ethe formula with these values
6*15 = 5(x+5)
90 = 5x + 25
65 = 5x
x = 13
EDIT: Here is the explanation for the formula
If you form triangles PCB and PAD you can find angle D and angle B are the same, because they are inscribed angles that intersect the same arc of the circle. Also angle P is the same on both triangles since they are the same angle, so this means both triangles are similar.
This means DA is similar to BC, AP is similar to CP and PD is similar to PB. Similar sides means if you can multiply one side by a number to get to its similar side, then you can multiply all sides by that value to get all sides of that similar triangle.
This also means if you divide one side by its similar side you get the scale value, so this means if you do it to two different sets of similar sides you get the same number
[tex]\frac{PA}{PC}=\frac{PD}{PB}\\PA*PB = PC*PD[/tex]
Surface area question:
Answer:
190π (not part of the answer choices)
Step-by-step explanation:
The surface area of a cylinder can be found using the formula below:
[tex]SA=2\pi r^2+\pi dh[/tex] where [tex]r[/tex] is the radius of the base, [tex]d[/tex] is the diameter of the base and [tex]h[/tex] is the height of the cylinder.
Plug in the given values
[tex]SA=2\pi (\frac{10}{2}) ^2+\pi (10)(14)\\SA=2\pi (\frac{100}{4})+140\pi\\SA=2\pi (25)+140\pi\\SA=50\pi+140\pi\\SA=190\pi[/tex]
Therefore, although this answer isn't one of the choices, the surface area of the cylinder is 190π.
I hope this helps!
Question in photo! answer asap! will give brainliest!
Answer:
Option B
Step-by-step explanation:
When you put option b in y intercept form, the slope is -3/2 which is the negative reciprocal of 2/3, making the lines perpendicular.
3x + 2y = -4
-3x -3x
2y = -3x -4
