Answer:

1,166 is the SA

correct me if im wrong somehow

Step-by-step explanation:

a wobble ball is a sphere

circumference=8(pi)

242=8(3.14)

so 242 divided by 25.12

this ends up with 9.633757961783439, which is the radius of the circumference

SA of a sphere= 4(pi)r²

SA=4(3.14)9.633757961783439²

SA=4(3.14)92.80929246622581

SA=1,165.684713375796

rounded to the nearest whole # = 1166

Answer:

  w = 8t

Step-by-step explanation:

If we assume that the ounces of water are proportional to the time, then the equation will look like ...

  w = kt

for some constant k.

Solving for k, we find ...

  k = w/t

Using the given values, we find k to be ...

  k = (32 ounces)/(4 seconds) = 8 ounces/second

The units are stated in the definitions of the variables, so we can write the equation as ...

  w = 8t

Answer:

B

Step-by-step explanation:

We want to find the point-slope equation of a line that passes through the points (-1, 4) and (8, -2).

Point-slope form is given by:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, let's find the slope of the line first. We can use the slope formula:

[tex]\displaystyle m=\frac{\Delta y}{\Delta x}=\frac{-2-4}{8-(-1)}=\frac{-6}{9}=-\frac{2}{3}[/tex]

We can choose (-1, 4) as our point. So, (x₁, y₁) = (-1, 4).

Substitute:

[tex]\displaystyle y-(4)=-\frac{2}{3}(x-(-1))[/tex]

Simplify:

[tex]\displaystyle y-4=-\frac{2}{3}(x+1)[/tex]

Therefore, our answer is B.

Answer:

  A.  2.1

Step-by-step explanation:

Put the numbers in the equation and do the arithmetic.

  1/R = 1/(3 1/2) +1/(5 1/4)

  1/R = 1/(7/2) +1/(21/4) = 2/7 +4/21 = (6 +4)/21

  R = 1/(10/21) = 21/10

  R = 2.1

there you go the correct ans

============================================================

Explanation:

He sold $4950 worth of items. Take 12% of this amount to get

12% of 4950 = 0.12*4950 = 594

So he earns $594 in commission on top of the $350 base salary paid every week. In total, he earns 594+350 = 944 dollars for that week

This isn't the per week pay because he would need to sell exactly $4950 worth of goods each week to keep this same weekly pay.

Answer:

x=4 and y=−4

Step-by-step explanation:

Let's solve your system by elimination.

−x−2y=4;3x+2y=4

−x−2y=4

3x+2y=4

Add these equations to eliminate y:

2x=8

Then solve 2x=8 for x:

2x=8

2x

2

=

8

2

(Divide both sides by 2)

x=4

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

−x−2y=4

Substitute 4 for x in−x−2y=4:

−4−2y=4

−2y−4=4(Simplify both sides of the equation)

−2y−4+4=4+4(Add 4 to both sides)

−2y=8

−2y

−2

=

8

−2

(Divide both sides by -2)

y=−4

Answer:

answer is option D

Step-by-step explanation:

(-2 , 4) = (x1 , y1)

(6 , -4) = (x2 , y2)

midpoint = (x1 + x2/2 , y1 + y2/2)

=(-2 +6/2 , 4+(-4)/2)

=(4/2 , 0/2)

=(2 , 0)

Answer:

It must be a rectangle with dimension of either 1 by 8  or 2 by 4

Step-by-step explanation:

V = l*w*h

32 = l*w*4

32/4 = l*w*4/4

8 = l*w

We could have 1*8

We could have 2*4

It must be a rectangle

It must be a rectangle with dimension of either 1 by 8  or 2 by 4

Answer:

He should have subtracted 2 from each side to find the solution for x+2 =0

Step-by-step explanation:

(x + 2)(x - 7) = 0

Using the zero product property

x+2 = 0   x-7=0

x+2-2=0-2    x-7+7=0+7

x = -2            x=7

He should have subtracted 2 from each side to find the solution for x+2 =0

Step-by-step explanation:

the steps he took are correct but the answer of x is somehow wrong because

(x+2)=0

x = -2

and not x = 2

Answer:

(2/3) foot =  8 inches

Answer:

They are congruent

Step-by-step explanation:

The reason that WK is congruent to WL is because both come from the same origin of W and they both end up in the same place on their side. Which means if WK and WL are congruent, that means that AK and AL are congruent as well.

Answer:

Is it a square? If so, then the other side would be a 98 since all sides in a square are equal

The answer is 'Right'.

Step-by-step explanation:

Sum of angles in a triangle = 180°

Angle C = 180 - 58 - 32

= 90°

90° is defined as a right angle.

Therefore, triangle ABC is classified as a right-angled triangle.

Step-by-step explanation:

Answer:

I think he should continue with the same rate of Rs300 per dozen to gain profit of Rs2100

At the rate of Rs 90 pre 5 apples he have to pay Rs 5400 for 300(25 dozen) apples.

total he have 25 dozen of apples.if he sold 12 dozen of appels at 300 per dozen then he earns Rs 3600. according to the merchant goal he wanted to make profit of 2100.we will add rs 2100 to CP hence we will get SP of Rs 5400+2100=7500. if he had already sell 12 dozens at rs 3600 then we will reduce the amount from SP hence we will get Rs 3900 to be earn. 13 dozens of apple is left so we can divide 3900/13 and we will get Rs 300.

if he continues selling those remaining 13 dozens of apple at the same rate the he can make profit of rs 2100.

Step-by-step explanation:

Given the data :

8000, 8000, 7000, 11000, 15000, 17000, 20000, 1000000.

Mean = Σx / n = 1086000 / 8 = 135750

Median = 1/2(n+1)th term = 8000

The lower quartile :

Q1 = 1/4(n+1)th term

Q1 = 8000

Q3 = 3/4 (n+1)th term

Q3 = 18500

IQR = 18500 - 8000 = 10500

OUTLIER :

8000 - (1.5*(10500)) = - 7750

18500 + (1.5*(10500)) = 34250

10% trimmed mean

10% * 8

Cut off 1 from the top and bottom

Data becomes : 8000, 8000, 11000, 15000, 17000, 20000

Given:

The conic equation is:

[tex]2x^2+Cy^2+3x+5y+1=0[/tex]

To find:

The value of C such that the given conic equation make a parabola.

Solution:

The general for of conic equation is:

[tex]Ax^2+Cy^2+Dx+Ey+F=0[/tex]

This equation represents a parabola is either A=0 or C=0 but not both equal to zero.

The given equation is:

[tex]2x^2+Cy^2+3x+5y+1=0[/tex]

Here, coefficient of [tex]x^2[/tex] is A=2 and coefficient of [tec]y^2[/tex] is C.

Since A is not equal to 0, therefore C must be equal to 0 to form a parabola.

Therefore, the only value of C is 0.
