I just need some help in math. This problem specifically
Answer:
∠ ABD = 37° , ∠ DBC = 58°
Step-by-step explanation:
∠ ABD + ∠ DBC = ∠ ABC , substitute values
2x + 23 + 9x - 5 = 95 , that is
11x + 18 = 95 ( subtract 18 from both sides )
11x = 77 ( divide both sides by 11 )
x = 7
Then
∠ ABD = 2x + 23 = 2(7) + 23 = 14 + 23 = 37°
∠ DBC = 9x - 5 = 9(7) - 5 = 63 - 5 = 58°
Step-by-step explanation:
Here are all the steps. First, you need to find the value of x . After finding x , just put the answer in the equation and calculate it .

Tyron made 60 cakes. He gave 20% of his cakes to Ana . And 1/6 of his cakes to Dora. What fraction of the 60 cakes does he have left?
Answer:
19/30
Step-by-step explanation:
Total cakes made by Tyron = 60
Cakes given to Ana = 20% of 60
[tex]=\dfrac{20}{100}*60\\\\= 2*6\\\\= 12 \ cakes[/tex]
Number of cakes given to Dora= [tex]\dfrac{1}{6}*60=10[/tex]
Remaining cakes = 60 - ( 12 +10)
= 60 - 22
= 38 cakes
Fraction of left cakes = [tex]\dfrac{38}{60}=\dfrac{19}{30}[/tex]

Which of the following numbers are greater than -4.5 and less than -0.5?
Lets form a inequality
x is greater than -4.5[tex]\\ \sf\longmapsto x>-4.5[/tex]
x is less than -0.5[tex]\\ \sf\longmapsto x<-0.5[/tex]
Now
[tex]\\ \sf\longmapsto -4.5\lt x\lt -0.5[/tex]
Hence
[tex]\\ \sf\longmapsto x=\left\{-4.4,-4.3\dots -0.7,-0.6\right\}[/tex]

2
(x+1)(x−5)
Answer:
see below
Step-by-step explanation:
f(x) = -2/3 (x+1) (x-5)
First find the zeros
0 = -2/3 (x+1) (x-5)
Using the zero product property
x+1 =0 x-5=0
x= -1 x = 5
Then find the y intercept
y = -2/3 (0+1)(0-5)
- 2/3 (1)(-5)
+10/3
We know that this is a parabola that opens downward
Simplify
y=-2/3(x+1)(x-5)y=-2/3(x(x-5)+x-5)y=-2/3(x²-5x+x-5)y=-2/3(x²-4x-5)Graph attached

Step-by-step explanation:
You plan to cut a board into 3 pieces to repair part of a railing. You are going to cut the two ends of the board off into two equal pieces that are 1.1 feet long, if the remaining piece needs to be 2.30 times longer than the each of the first two cuts what length board should you buy? Round to the nearest tenth.
Answer:
The board should be 4.7 feet long.
Step-by-step explanation:
To find the remaining piece, you just multiply 1.1 by 2.3 which is 2.53. That's the length of the remaining piece.
Then you add all the pieces together.
1.1+1.1+2.53 =
4.73
Round and add label.
4.7 feet

How many names would be said if in a room of 875 people each said everyone name?
Answer:
765625
Step-by-step explanation:
because 875x875 is 765625
Answer:
765,625 names if each says their own name, 764,750 if they don't. (Although, if you wanna get technical, only 875 names are being said, since they're repeating the same names over and over again)
Step-by-step explanation:
Alrighty, this is complicated. Just to make it easier, we're going to switch the word "names" to "words."
There are 875 people in the room, and each one of them is saying 875 words (assuming it includes their own name). So to figure out how many words would be said, you multiply 875 by 875, which gives you 765,625 words. If they say everyone's name EXCEPT their name, then subtract 875, which gives you 764,750.

V=1/3πr²(h-1) find h
Answer:
[tex]h=\displaystyle \frac{3V}{\pi r^2}+1[/tex]
Step-by-step explanation:
Hi there!
[tex]V=\displaystyle\frac{1}{3} \pi r^2(h-1)[/tex]
Divide both sides by [tex]\displaystyle\frac{1}{3} \pi r^2[/tex]:
[tex]\displaystyle \frac{V}{\displaystyle\frac{1}{3} \pi r^2}=(h-1)[/tex]
[tex]\displaystyle \frac{3V}{\pi r^2}=h-1[/tex]
Add 1 to both sides:
[tex]\displaystyle \frac{3V}{\pi r^2}+1=h[/tex]

does this form a right triangle 8,10,6
Answer:
Yes, it does. We can check by using the Pythagorean theorem (P.t.).
P.t.: a^2 + b^2 = c^2
a = 6, b = 8, c = 10
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
Brainliest, please!
Answer:
Step by step answer.
Yes
a^2 + b^2 = c^2
8^2 + 6^2 = 10^2
64 + 36 = 100
100 = 100
The Pythagorean Theorem works. C is always assumed to be the hypotenuse because it is the longest line It's position does not matter. If you did the problem like this
6^2 + 10^2 = 8^2
Of course this would not work, but it would also disobey the convention that c is the longest side.

Answer:
[tex]a \times a \times b \times b \times b \times c \times c = {a}^{2} \times {b}^{3} \times {c}^{2} \\ thank \: you[/tex]
Find the area of a cell phone screen with an 8 inch diagonal that has an aspect ratio of 2:3.
Round answer to the nearest square inch.
The answer if any body knows it
Answer:
[tex]A=\pi(336)[/tex]
[tex]A=1055.575[/tex]
Step-by-step explanation:
1. Approach
One is given a prism. The base of the prism is a quarter of a circle, the prism's length is also given. The easiest method to find the volume of the prism is to find the area of the quarter of the circle, then multiply the result by the length of the prism.
2. Find the area of the quarter circle
The following formula can be used to find the area of a circle,
[tex]A_c=(\pi)(r^2)[/tex]
Since one is trying to find the area of a quarter of a circle, one must multiply this formula by ([tex]\frac{1}{4}[/tex]). Please note that the parameter (r) represents the radius of the circle or the distance from the center of the circle to the circumference or outer edge of the circle. The parameter ([tex]\pi[/tex]) represents the number ([tex]3.1415...[/tex]).
[tex]A_c=\frac{1}{4}(\pi)(r^2)[/tex]
Substitute the given values into the formula and simplify to evaluate,
[tex]A_c=\frac{1}{4}(\pi)(r^2)[/tex]
[tex]A_c=\frac{1}{4}(\pi)((8)^2)[/tex]
[tex]A_c=\frac{1}{4}(\pi)(64)[/tex]
[tex]A_c=(\pi)(16)[/tex]
[tex]A_c\approx 50.2655[/tex]
3. Find the volume of the prism
Now multiply the area of the quarter circle by the length of the prism to find the volume of the prism. Note that the parameter (l) represents the length of the prism,
[tex]A=A_c(l)[/tex]
Substitute and simplify to evaluate,
[tex]A=(\pi)(16)(21)[/tex]
[tex]A=\pi(336)[/tex]
[tex]A=1055.575[/tex]
