Answer:
6.2 feet
Step-by-step explanation:
we can determine the radius from the volume of the hot tub
volume of a sphere = (4/3) x (n) x (r^3)
n = 22/7
r = radius
1000 = (4/3) x (22/7) x r^3
divide both sides of the equation by (4/3) x (22/7)
238.636 = r^3
find the cube root of both sides
r = 6.20 feet
In her metalwork class, Anja cut a square of
tin, of edge 3.7 cm, from a larger square of
edge 6.3 cm. What area of tin was left?
Given:
Anju cut square of tin, of edge 3.7 cm, from a larger square of edge 6.3 cm.
To find:
The area of the remaining tin.
Solution:
Area of a square is:
[tex]Area=a^2[/tex]
Where, a is the edge of the square.
Area of the smaller square is:
[tex]A_1=(3.7)^2[/tex]
[tex]A_1=13.69[/tex]
Area of the larger square is:
[tex]A_2=(6.3)^2[/tex]
[tex]A_2=39.69[/tex]
The area of the remaining tin is:
[tex]A=A_2-A_1[/tex]
[tex]A=39.69-13.69[/tex]
[tex]A=26[/tex]
Therefore, the area of the remaining tin is 26 sq. cm.

The figure shows a kite inside a rectangle. Which expression represents the area of the shaded region?
A. 2x^2
B. 4x^2
C. 6x^2
D. 8x^2
Thanks!!
[tex] \huge \mathrm{Answer࿐ }[/tex]
Fig - 1 : Rectangle
length = 3x + x = 4x width = x + x = 2x[tex] \boxed{\mathrm{Area = length \times width}}[/tex]
[tex]4x \times 2x[/tex][tex]8 {x}^{2} [/tex]_____________________________
Fig - 2 : Kite
[tex] \boxed{\mathrm {Area = \dfrac{1}{2} \times d_1 \times d_2 }}[/tex]
[tex] \dfrac{1}{2} \times 4x \times 2x[/tex][tex]4 {x}^{2} [/tex]_____________________________
Area of shaded region :
Area of rectangle - Area of kite [tex]8 {x}^{2} - 4 {x}^{2} [/tex][tex]4 {x}^{2} [/tex]So, Correct option is B. 4x²

Both packs are too expensive but $2.5 per stable isthe better value.
What are the solutions to this equation?
16x2 + 9 = 25
Answer:
Step-by-step explanation:
Solution
= −1
= 1
Answer: x=-1,1
Step-by-step explanation:
16x^2+9=25 first we subtract 9 from the right and left sides.
16x^2=16
Divide both sides by 16 to isolate x
x^2=1
Take the square roots of both sides to isolate x completely.
x=1,-1

a dice is rolled 60 times, what is the probability of it landing on 4
Find the normal approximation to the chance that the face with six spots appears between 9, 10, or 11 times.
The exact chance that the face with six spots appears 9, 10, or 11 times?
my solution; in one roll of the die P(6 spots)=16 In 60 rolls of the die the expected number of times the face with 6 spots appears is given by E(X)=Mean=606=10 times.
SE(6spots)=SD=SQR(606⋅56)=2.8868
Applying the normal approximation to the chance that the face with six spots appears 10 times, I obtain the following: mean = 10
Standard deviation=2.8868
Using the continuity correction of 0.5 the following z-scores are found: z1=(9.5−10)/2.8868=−0.1732 and z2=(10.5−10)/2.8868=0.1732 Subtracting the cumulative probabilities for the two z-scores gives 0.5688−0.4312=0.1376 which is the approximate chance that the face with six spots appears 10 times. find the six spots appears between 9,10, or 11?
The exact chance that the face with six spots appears 10 times is found from
60C10(16)10×(56)50=0.137 find six spots appears 9, 10 or 11 times

Answer:
145°
Step-by-step explanation:
180-35=145
Answer:
145°
Step-by-step explanation:
subtract 35 from 180
because a straight line is 180
180- 35
145°
to check,
add 35 and 145 to make sure it adds up to 180
it does.
What is the probability of rolling a 1 ora 4 on a number cube labeled 1 through 6?
Answer:
For each number, there is a 1/6 probability of rolling it (so 1/6 for the 1 and also 1/6 for the 4).
This means that the probability of rolling either a 1 or a 4 on a given roll is
1 /6 + 1 /6 = 2/6 = 1/3
hope this answer helps you.....
Answer:
Is 1/6

Step-by-step explanation:
Nadia needs 2/5 cup of orange juice for a punch recipe. She will double the recipe to make punch for a party. Which statement is true?
Answer:
Step-by-step explanation:
There's not a lot to go on with the details provided in the question, but based on all you said, if there isn't more to the question, then the true statement is the fact that Nadia needs 2/5 cup of orange juice for punch recipe.
Twice that amount is 4/5, and logically, that can't suffice in a party, except it's a party of 3, maybe 5 people. I'm assuming the people in the party would be much more than that. Makes the fraction impossible

So say someone did 1000 push ups a day for 8 years 2920 days in 8 years and you want to do the same amount but in 2 months how many would you have to do a day
Answer:
48,667 if you round it..
Step-by-step explanation:
1000x2920 = 2,920,000
divided by 2 months
2,920,000/2 = 1,460,000
and theres 30-31 days in a month
1,460,000/30 = 48,666.67

I SHALL REWARD THEE WITH BRAINLIEST Change -2Y - 2X = -6 to the slope intercept form of the equation of a line (I NEED EXPLANATIONS FOR FURTHER QUESTIONS I GET STUCK ON) :3 ty and hawwo
Answer:
y = -x + 3
Step-by-step explanation:
First of all, you need to memorize several forms of the equation of a straight line. Here you have -2y - 2x = -6 in "standard form" and want the equivalent equation in "slope intercept form," y = mx + b.
To get this, solve the first equation for y by dividing all three terms by -2:
y + x = 3.
Then solve this result for y:
y = -x + 3
This is the desired equation in slope-intercept form.

Answer:
13). -2x³ + x² + 1 14). x + 10y - 10z 15). -2x³ + x² + 1
Step-by-step explanation:
13). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² - 3 + 4
= -2x³ + x² + 1
14). (3x + 4y - 3z) - (2x - 6y + 7z)
= 3x + 4y - 3z - 2x + 6y - 7z
= 3x - 2x + 4y + 6y - 3x - 7z
= x + 10y - 10z
15). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² + 4 - 3
= -2x³ + x² + 1

Answer:
8) 50°, 50°, 130°, 130°10) 120°Step-by-step explanation:
Ex 8Adjacent interior angles of a parallelogram are supplementary
Let the small angle is x, the other angle is:
2x + 30°The sum of two angles is 180°
x + 2x + 30° = 180°3x = 150°x = 50°The angles are 50°, 50°, 130°, 130°
Ex 10Sum of interior angles of a pentagon is:
S = 180°(5 - 2) = 540°Two of the angles are supplementary, so they sum to 180°
The sum of the remaining 3 angles is:
3x = 540° - 180°3x = 360°x = 120°Each of the congruent angles is 120°
