Answer:
11x-8
Step-by-step explanation:
First distribute the 3 and 2. (Only in the parenthesis!):
3(x-2)+2(4x-1)
3x-6+8x-2
Combine like terms:
3x+8x=11x
-6-2=-8
So the answer is:
11x-8
What are 3 tips to solve quadratic equations using the quadratic formula?
Answer:
Step-by-step explanation:
I would say the first thing you should always do is graph the quadratic. See where the x intercepts are. If there aren't any, go onto step 2. If there are, make note of them. The quadratic formula will give you the same answer. You can use Desmos to graph the quadratic.The second thing to do is to test what is under the square root (called the discriminate). If you get something weird like the square root of a minus number, then the graph should have told you that the quadratic does not cross the x axis at all.When you have done those two things, you are ready to use the whole quadratic. Watch out for -b at the beginning. If b is - 4 (for example) the -b will make it 4Jesse has reached 16% of his weekly reading time goal so far this week. If he has read for a total of
32 minutes this week, what is his weekly reading time goal in minutes?
x = time goal
16% = .16
.16 x = 32
x = 32/.16 = ___________ minutes
Jesse' weekly reading time is an illustration of ratio and proportion.
Jesse' weekly reading time is 200 minutes
Represent the reading time with x.
16% of his weekly reading time is given as 32 minutes
This is represented using the following equation
[tex]16 \% \times x = 32[/tex]
Express 16% as decimal
[tex]0.16\times x = 32[/tex]
Divide both sides by 0.16
[tex]x = 32/0.16[/tex]
[tex]x = 200[/tex]
Hence, Jesse' weekly reading time is 200 minutes

25 POINTS GIVING BRAINLIEST TO WHOEVER ANSWERS UT RIGHT!!A right triangle has hypotenuse with a length of 13 cm. The length of one leg is 5 cm. What is the area of the triangle?
A.65
B.60
C.32.5
D.30
Answer:
Hello! answer: 30
Step-by-step explanation:
13 × 13 = 169
5 × 5 = 25
169 - 25 = 144
12 × 12 = 144 therefore 12 is the missing leg
so we will use this to find the area so...
12 × 5 = 60 60 ÷ 2 = 30 therefore the answer is 30 hope that helps!

Danny is measuring rainfalll.For a.Science project in september 7/8 inch of rain fell in october 2 1/4 invhes of rain fell how much. More rain fell in october than september
Answer: [tex]1\dfrac{3}{8}\ \text{inch}[/tex]
Step-by-step explanation:
Given
Rainfall in September is [tex]\frac{7}{8}[/tex] inch
Rainfall in October is [tex]2\frac{1}{4}[/tex] inch
Convert mixed fraction into fraction
[tex]\Rightarrow 2\dfrac{1}{4}=\dfrac{9}{4}\ \text{inch}[/tex]
Difference between the two gives that how much more rain fall in October compared to September
[tex]\Rightarrow \dfrac{9}{4}-\dfrac{7}{8}\\\\\Rightarrow \dfrac{18-7}{8}\\\\\Rightarrow \dfrac{11}{8}\ \text{inch or}\\\\\Rightarrow 1\dfrac{3}{8}\ \text{inch}[/tex]
Find the cosine of ∠G (Must give explanation)
also why does my calculator say its undefined if I do the cos invert of (85/77) ??
cos^-1(85/77) = undefined ?? why
Answer:
[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]
Step-by-step explanation:
Recall that cosine is the ratio of the adjacent side to the hypotenuse:
[tex]\displaystyle \cos(G)=\frac{\text{adjacent}}{\text{hypotenuse}}[/tex]
The hypotenuse is always the side opposite to the right angle. In this case, it is
85.
The adjacent side to G is 36.
Therefore:
[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]
For your other question, remember that in a right triangle, cosine is the ratio of the adjacent side to the hypotenuse.
As you know, the hypotenuse is always the longest side in a right triangle.
Therefore, the ratio of the adjacent side to the hypotenuse will never be greater than 1.
Since 85/77 is greater than 1, it is undefined.
The same applies to sine as well.

Substitute
Arc YX + 110° + 146° = 360°
Arc YX + 256° = 360°

The figure is made up of a cylinder and 2 cones. What is the volume of the composite figure? Use 3.14 for Pi. Round to the nearest hundredth.
Please help!!!!!
A cylinder and 2 cones. All have a radius of 2 millimeters. The cones have heights of 4 millimeters and 2 millimeters, and the cylinder has a height of 5 millimeters.
Recall the formulas V = B h and V = one-third B h
Answer——————- millimeters cubed
Answer:
96.29 mm^3
Step-by-step explanation:
Cylinder
V = pi r^2 h
V = 3.14 ( 2)^2 ( 5)
V = 3.14 *4*5
V =62.8 mm^3
Cone
V = 1/3 pi r^2 h
V = 1/3 (3.14) 2^2 ( 4)
V =1/3 (3.14) 4*4
V =16.746666666 mm^3
There are 2 cones so multiply by 2
Both cones = 33.493333333333 mm ^3
Add the cones and the cylinder together
62.8+33.493333333 =96.293333333
Rounding to the nearest hundredth
96.29 mm^3
