Answer:
r = 51.96 inches
Step-by-step explanation:
[tex]V_{cone} = \pi {r}^{2} h \\ \\ \implies \: r^{2} = \frac{V_{cone}}{\pi h } \\ \\ \implies \: r^{2} = \frac{942}{3.14 {(9) } }\\ \\ \implies \: r^{2} = \frac{942}{3.14 {(9) } } \\ \\ \implies \: r^{2} =2700 \\ \\ \implies \: r= \sqrt{2700} \\ \\ \implies \: r=51.96 \: inches[/tex]

Ms. B is making snickerdoodle cookies. Her recipe uses one and a half teaspoons of cinnamon to make two dozen cookies. If she needs to make thirteen dozen cookies to give one cookie to each of her students, how much cinnamon will she need? There are three teaspoons in one tablespoon. How many tablespoons and teaspoons will Ms. B need?
Answer:
First we must learn to dissect a question.

[tex]|\displaystyle\frac{x-1}{2} |=7[/tex]
Let's say that x-1 is negative:
[tex]\displaystyle\frac{-x+1}{2} =7[/tex]
The first step is to multiply both sides by 2:
[tex]\text{-x+1=14}[/tex]
Now, move 1 to the right, using the opposite operation:
[tex]\text{-x=14-1}[/tex]
[tex]\text{-x=13}[/tex]
Divide both sides by -1:
[tex]\text{x=-13}[/tex]
Note: Since the negative sign is already entered, all you need to enter is 13.I hope you find my answer helpful.
Good luck!

Problem 2
Rewrite the fraction 2/3 into 4/6. This is valid because we multiply top and bottom by 2.
2/3 = 4/6
Now compare the fractions for Wednesday and Tuesday in that order. We have 4/6 and 5/6. We can ignore the denominators because they effectively cancel out. The numerators will form the answer.

divide 182kg in the ratio 2:3:8
The equivalent values for the ratio 2 to 3 to 8 is 28kg, 42kg and 112kg
Ratio and proportionsGiven the following parameters
Total weight = 182kg
If the weight is divide in the ratio 2:3:8, th3n the total ratio will be;
total ratio = 2 + 3 + 8
Total ratio = 13
For the ratio of 2;
Portion =2/13 * 182
Portion = 28kg
For the ratio of 3;
Portion =3/13 * 182
Portion = 42kg
For the ratio of 8;
Portion =8/13 * 182
Portion = 112kg
Hence the equivalent values for the ratio 2 to 3 to 8 is 28kg, 42kg and 112kg

8) Given: Graham's monthly bank statement with deposits and withdrawals:
-25.20,−25.20,52.75,-22.04,−22.04,-8.50,$94.11
If Graham's balance in the account was $47.86 at the beginning of the month .
Then the account balance at the end of the month =
=47.86+(-25.20+ 52.75- 22.04- 8.50+ 94.11)
=47.86+(52.75 + 94.11 − 25.20− 22.04− 8.50)
=47.86+(146.86− 55.74)
47.86+(91.12)=47.86+91.12= 138.98
Thus, the account balance at the end of the month= $138.98

HURRY 20 POINTS! Which ordered pair is a solution of the equation shown?
y=3/4x+1/2
Answer:
A
Step-by-step explanation:
3/4*(-4/3) + 1/2 = -1 + 1/2 = -1/2
First, B is not the answer, because if x = 0, the whole equation would've been 0.
A) -4/3 ; -1/2
Replace x and y with the 2 fractions, we have : 3/4 x (-4/3) + 1/2 = -1/2
-1 + 1/2 = -1/2 (true)
So, A is correct
But to make sure, we'll go over C and D also.
C) 4/3 ; 1/2
Replace x and y : 3/4 x 4/3 + 1/2 = 1/2
1 + 1/2 = 1/2 (not true)
So this is not the answer
D) 4 ; 3/2
Replace x and y : 3/4 x 4 + 1/2 = 3/2
3 + 1/2 = 3/2 (not true)
So, A is correct.
8(3f-6)<-24 solve each inequality.
Answer:
f < 1
Step-by-step explanation:
8(3f−6)<−24
Divide both sides by 8. Since 8 is positive, the inequality direction remains the same.
3f−6< [tex]\frac{-24}{8}[/tex]
Divide −24 by 8 to get −3.
3f−6<−3
Add 6 to both sides.
3f<−3+6
Add −3 and 6 to get 3.
3f<3
Divide both sides by 3. Since 3 is positive, the inequality direction remains the same.
[tex]f<\frac{3}{3}[/tex]
Divide 3 by 3 to get 1.
f < 1
Solution:
Note that:
Given inequality: 8(3f - 6) < -24Simplify the inequality to obtain the inequality for f.
8(3f - 6) < -24=> (24f - 48) < -24=> 24f - 48 < -24=> 24f < -24 + 48=> 24f < 24=> f < 1The simplified inequality is f < 1.

B) complementary
C) vertical
D) straight
Answer:
Adjacent
Step-by-step explanation:because it is right next to 4
The correct term that can be used to classify angles 3 and 4 is: A) adjacent.
What are Adjacent Angles?If two angles lie next to each other and they share one side and a vertex, then, both angles can be called adjacent angles.
An example of such angles that share a common side and a vertex are angles 3 and 4 as shown in the image.
Therefore, the correct term that can be used to classify angles 3 and 4 is: A) adjacent.

PLEASE ASAPPPPP I NEED ITTTT
Step-by-step explanation:
If a system has at least one solution, it is said to be consistent. If a consistent system has exactly one solution, it is independent. If a consistent system has an infinite number of solutions, it is dependent.
and if it has no solutions (lines are parallel), then it is inconsistent.
I think that information can be easily found on the internet.
so, the first one on the left is consistent independent. it has a unique solution at (-2, 1). the solution is always the crossing point of the lines.
the middle system is consistent dependent. both lines are identical, and so we have infinite many "crossing points" or solutions.
the right system is inconsistent, as 2 parallel lines have no solution at all.

Answer:
y = ½x + 5
Step-by-step explanation:
slope of the line is : a= (8-5)/(6-0) = ½ it's the coefficient of x too.
y = ax + b → y = ½x + b
consider the point (0,5) → 5 = ½(0) + b → b = 5
so equation of the line is: y = ½x + 5
Answer:
Step-by-step explanation:
(6,8) ; (0,5)
At y-intercept x is o.
y=intercept = b = 5
Equation of line in slope intercept form: y = mx + b
y = mx + 5
In this, Plugin the values of the point (6 ,8)
8 = 6m + 5
8 - 5 = 6m
3 = 6m
Divide both sides by 6
3/6 = 6m/6
1/2 = m
Equation of the line:

The circumference of a circle is 4pi. Find its radius, in feet.
Answer: 2
Step-by-step explanation:
The circumference of a circle is 2*radius*pi.
We can set up an equation as we know the circumference as 4pi.
4pi = 2*radius*pi
Divide both sides by pi:
4 = 2*radius
Divide both sides by 2:
radius = 2
Answer:
2 ft
Step-by-step explanation:
The equation for circumference is:
[tex]C=2\pi r[/tex]
We can plug in the given value for circumference to solve for the radius.
[tex]4\pi=2\pi r[/tex]
Divide both sides by 2π
[tex]\frac{4\pi}{2\pi}=r\\r=2\ ft[/tex]
A circular sprinkler system is installed and waters an area of 78.5 square yards. What is the radius of the circle? Draw a picture and show all your work.
Answer:
The radius of the circle is about 5
Step-by-step explanation:
The formula for the radius of the circle with a area is:
- R= the square root of the area divide by pi ( π)
or - R= the square root of A/ π
Plug in 78.5 into the formula
then you get the radius which is 5.
