What is the value of s in the equation below? S + 1 1/2 = 10 1/2
Answers
Answer:
S=9
Step-by-step explanation:
10[tex]\frac{1}{2}[/tex] - 1[tex]\frac{1}{2}[/tex] = 9
Answer:
s=9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
s+3/2=21/2
Step 2: Subtract 3/2 from both sides.
s+3/2−3/2=21/2−3/2
s=9

Gravel is being dumped from a conveyor belt at a rate of 15 ft3/hr and its coarseness is such that it forms a pile in the shape of an inverted right cone whose height is three times its base radius. How fast is the height of the pile increasing when the pile has a height of 10 ft
Answers
Answer:
0.43 ft/hr
Step-by-step explanation:
dv/dt = 15ft³/hr
Height = 10ft
We are required to get dh/dt
h = 3r
r = h/3
Formula for volume = 1/3πr²h
We put value of h
1/3π(h/3)²h
= 1/3π(h²/9)h
= 1/3πh³/9
= πh³/29
dv/dt = 1/27π.3h²dh/dt
= dv/dt = πh²/9dh/dt
Remember dv/dt = 15
When we put this in we get
dh/dt = 15x9/3.142x10²
= 135/314.2
= 0.43 ft³/hr

At a park, 80 out of the 200 people there are men. The rest are women.
What percent of the people are women?
Answers
120/200=60% women
Answer: 3/5 of the park population is female, or 60 percent. How? 80:200 can be simplified to 40:100, and this in fraction form is 40/100. We can further simplify it by dividing both by 10 to get 4/10, and then by 2 to get 2/5. 5 - 2 = 3, so 3/5 is the answer.

Line I is parallel to line m. If the
measure of 26 is 75°, what is the
measure of Z2?
1/2
4/3
5/6 = 75°
78
Answers
Answer:
75°
Step-by-step explanation:
All parallel lines will meet their transversal (the line going through them) at the same angle. We can imagine sliding line m up to line l until the two are overlapping, and naturally all of those angles at the intersection will overlap, too. ∠6 will overlap ∠2, so the two angles are congruent. If m∠6 = 75°, then m∠2 = 75°!

which answer would go with this problem (match the quadratic graph to an equation)
Answers
Answer:
Second (middle) option
Step-by-step explanation:
You can clearly tell from the graph that the y intercept is at 0,0
in [tex]ax^2+bx+c[/tex], c is always the y value of the y-intercept
in this case the value is 0 so there shouldn't be a visible "c" in the equation, which is why the answer is the middle option
