Answer:
h = 9 m
Step-by-step explanation:
[tex]V_{cone}=340\: m^3[/tex]
diameter (d) = 12 m
[tex]\implies radius\:(r)= \frac{12}{2}=6\:m[/tex]
[tex] \because \: V_{cone}= \frac{1}{3} \pi {r}^{2} h \\ \\ \implies \: h = \frac{3V_{cone}}{\pi {r}^{2} } \\ \\ \implies \: h = \frac{3(340)}{3.14 {(6)}^{2} } \\ \\ \implies \: h = \frac{1020}{113.04} \\ \\ \implies \: h = 9.02335456 \\ \\ \implies \: h \approx 9 \: m[/tex]
Can someone explain how to do this cause I’m confused
Answer:
51
Step-by-step explanation:
So basically, you just plug in the number after f for the letter x. In this case, it is 5 for x.
This gives you:
-5²+6(5)-4
-5²=25
6(5)=30
25+30=55
55-4 =

Please help. Solve the following system of linear equations by substitution. Show all work.
Y= -2
4x -3y=18
Answer:
The solution (3, -2).
Step-by-step explanation:
The easiest way to find this solution is inputting these two equations into Desmos Graphing Calculator!
Answer:
x = 3,y = -2
Step-by-step explanation:
Given data:
Y= -2
4x -3y=18
Solve:
Substitute the given y-value into 4x−3y=18 and solve for x
Since, y = -2,
[tex]4x-3(-2)=18[/tex]
[tex]4x+6=18[/tex]
[tex]4x+6-6=18-6[/tex]
[tex]4x=12[/tex]
[tex]\frac{4x}{4}=\frac{12}{4}[/tex]
[tex]x = 3[/tex]
The solution to the system of equations is x = 3, y = -2

Which of the following functions best describes this graph?
A. y = x^2 + x - 12
B. y = x^2 - 9x + 18
C. y = x^2 + 9x + 18
D. y = x^2 - 5x + 6
Dario purchased a party size sub, and he decides to share it with 3 of his friends. So, he cuts the sub into 4 equal pieces. However, another one of his friends also showed up, and there are now 5 people in total.
Part A
Now that the sub will be shared equally among 5 people, will each person get more or less sub? Briefly state why you think so.
Part B
Dario decides to take each one of the 4 pieces and share it equally among the 5 of them. First, he divides one piece into 5 equal parts and shares it, then the next one, and so on.
What fraction of the party size sub did each person get after all the parts were shared out? Briefly explain your reasoning.
The fraction illustrates that each person will get less sub since there are more people sharing it.
How to explain the fraction?In this case, Dario purchased a party size sub, and he decides to share it with 3 of his friends but another friend came. This means there will be less in to be shared.
The fraction of the party size sub did each person get after all the parts were shared out will be:
= 1/5 × 4
= 4/5
Therefore, each person gets 4/5.

Master Mason wants to treat all the
Kids at school. How packs of 15 fudge does he need for 151 children?
Answer:
11
Step-by-step explanation:
you would have to divid 15 from 151
151/15= 10.06
since you cant get a part of a pack you would have to round up which is 11 to treat all of the kids
Answer:
he will need 11 packs of fudge
Step-by-step explanation:
to answer this question you will divide 151 by 15 and you will get 10.066. you cannot bring 0.066 packs of fudge so you would bring one extra meaning you would bring 11 packs total.

Solution:
We know that:
Given equation: 1/4(x - 2) = 3 - (x + 1/6)Simplify the distributive property.
1/4(x - 2) = 3 - (x + 1/6)=> x/4 - 2/4 = 3 - x - 1/6Further simplify both sides.
x/4 - 2/4 = 17/6 - xSubtract 17/6 both sides.
x/4 - 2/4 - 17/6 = 17/6 - 17/6 - x=> x/4 - 6/12 - 34/12 = -x=> x/4 - 40/12 = -xSubtract x/4 both sides.
x/4 - x/4 - 40/12 = -x - x/4=> -40/12 = -5x/4Use cross multiplication.
=> -160 = -60xDivide -60 both sides.
-160/-60 = -60x/-60=> x = 160/60 = 2 40/60 = 2 2/3If you walk 15 miles in 8 hours, how many miles would you walk in 2 hours

i tried multiplying but it no work am i missing something?
Answer:
3 3/16 meters
Step-by-step explanation:
The volume of the box is the product of the length and width and height. You are given the length, and you are given a relation for the width. To find the height, you need to use the given relations to create an appropriate equation to solve.
One way you can do it is this:
V = LWH
If we use a value that is (1 9/16)W, then we have ...
(1 9/16)V = L·(1 9/16)W·H . . . . . multiply the above equation by 1 9/16
Putting the given values into this relation, we have ...
(1 9/16)(12 3/4) = (2 1/2)(2 1/2)·H . . . . . . remember, 2 1/2 = (1 9/16)W
H = (1 9/16)(12 3/4)/(2 1/2)² = (1275/64)/(25/4) = 51/16
H = 3 3/16 . . . meters
__
Additional comment
An alternative is to find the actual width:
(1 9/16)W = 2 1/2
W = (5/2)/(25/16) = 8/5 = 1 3/5
Then you would have ...
12 3/4 = (2 1/2)(1 3/5)·H = 4·H
H = (51/4)/4 = 51/16 = 3 3/16 . . . as above

Calculate the probability for the following situation: You are tossing a coin, then rolling a die, then drawing a card from a deck of cards. What is the probability that you will get: a head AND an odd number on the die AND a card greater than 3 (assume the ace is equal to 1) from the deck?
Answer:
Flipping the coin:
P( H ) = 1/2
---------------------
Rolling the die:
There are 6 numbers
1,2,3,4,5,6
3 of them are odd, so
P( odd ) = 3/6
P( odd ) = 1/2
Step-by-step explanation:
There are 52 cards in a deck
There are +9%2A4+=+36+
cards less than +10+
P( <10 ) = 36/52
P( <10 ) = 9/13

multiply probabilities

9 MULTIPLY BY 1 OVER 4 PLS HELP ^_^
Answer:
37 over 4
Step-by-step explanation:
Hi! I hope you're enjoying your day!
First, 9 times 1 is 9 (anything times 1 is itself)
Now, 9 over 4 is 9 divided by 4.
Is 9 divided by 4? Nope!
However, don't worry! The answer will be a fraction.
[tex]\bold{\displaystyle\frac{9}{4}}[/tex]
Can this fraction be reduced? No.
Why? Because 9 and 4 have no common factors, except 1.
And if you divide by 1, nothing will change.
Hence, the answer is
Improper Fraction: [tex]\boxed{\boxed{\bold{\displaystyle\frac{9}{4} }}}[/tex]
Mixed Number: [tex]\boxed{\boxed{\bold{2\frac{1}{4} }}}[/tex]
Hope everything is clear.
