What is 6 + 4/a + b/3 =
Answer:
8
Step-by-step explanation:
a = 4
b = 3
4 / a
= 4 / 4
= 1
b / 3
= 3 / 3
= 1
6 + 4 / a + b / 3
= 6 + 1 + 1
= 8
Answer:

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

Tucker's Road Paving Company used 646.5 tons of cement to pave 4 miles of roadway. To the nearest hundredth of a ton, how much cement, on average, did the company use per mile?
Answer:
161.63 tons
Step-by-step explanation:
Cement used per mile = total cement used / total miles
646.5 tons / 4 = 161.625 tons
161.63 tons to the nearest hundredth
the hundredth is the second number after the decimal place. To convert to the nearest hundredth, look at the number after the hundredth (the thousandth). If the number is greater or equal to 5, add 1 to the hundredth figure. If this is not the case, add zero
the thousandth term is 5, so 1 would be added to 2
A) 5
B) 6
C) 3
D) 1

Jesse 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

What is quadratic equation?Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations.
The given equation is;
[tex]\rm x^2 + 2x = 25\\\\x^2+2x-25=0[/tex]
The solutions to the quadratic equation is determined by the following formula;
[tex]\rm x =\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

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 4Can I get some help on this question pls

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.
