Step-by-step explanation:

2/3*d=40

d=40*3/2

d=60

Answer:

Step-by-step explanation:

let workers=n

time=t(weeks)

t=k/n ,where k is constant .

when t=8,n=3

8=k/3

k=24

t=24/n

n   2   4   6   12

t   12   6   4    2

Answer:

Your answer is X = 7

Step-by-step explanation:

Answer:

y/-3 = 1/6

y = 1/6 × 3

y = 0.5

Answer:

-1/2 and -0.5

Explanation :

Hey! Ok so you will plug in all the value in the y to find out if it equals to 1/6.

y ÷ -3 = 1/6

0.5 ÷ -3 = 1/6

-1/6 = 1/6 ---> NO

y ÷ -3 = 1/6

-1/2 ÷ -3 = 1/6

1/6 = 1/6 ---> YES

y ÷ -3 = 1/6

-0.5 ÷ -3 = 1/6

1/6 = 1/6 ---> YES

y ÷ -3 = 1/6

-18 ÷ -3 = 1/6

6 = 1/6 ---> NO

Hope this helps, and stay safe, happy, and healthy, thank you :) !!

Answer:

a=116.5°

b=116.5°

Step-by-step explanation:

360-95-32=233

233÷2=116.5

a and c are equal, so both are 116.5

Answer:

Step-by-step explanation:

let tacos be x and burritos be y

so, your 1st eqn. is 3x + 5y = 17.75

2nd eqn. is 4x+ 2y = 12

Solving the 2 eqns: Multiply eqn 1 with 2 and eqn 2 with 5

So: 6x+10y=35.5

-20x-10y=-60

=-14x=-24.5

x=24.5/14 = 1.75

Substituting the value of x in eqn 1 : (3*1.75)+5y=17.75

y = 2.5

x² + 10x + 25 = (x+5)²

Answer:

3. 273

4. 168

5. 189.25

Step-by-step explanation:

3. Triangle= .5 x 17 x 6 = 21

Rectangle= 18 x 14 = 252

252 + 21 = 273

4. Big rectangle (shaded)= 11 x18= 198

Small rectangle (right)= 5x4=20

Smaller rectangle (left)= 2x5=10

BR - (SR+SMR)

198-30=168

5. radius=5

Area of the circle= 25(pi)

Semi-circle= 39.25(not exact)

Rectangle= 10 x15=150

Rectangle + Semi-circle

150+39.25=189.25

Answer:

I think 235.5 mm cubed

Step-by-step explanation:

The formula for the volume of a cone is V=1/3hπr².

1/3 x 9 x π x 5² =

1/3 x 9π x 25 =

1/3 x 225π =

75π

let's say π=3.14

75 x 3.14 = 235.5

Answer:

Down below :)

Step-by-step explanation:

AC is 2.55-2.2= answer

Angle C is 90 degrees so angle A and B are both the same length I think.

Since 180 degrees is the total because it is a triangle, then 180-90=90/2=?

Answer: x^2/9 + y^2/4 = 1

Step-by-step explanation:

Answer: [tex]\frac{x^{2} }{9} +\frac{y^{2} }{4} =1[/tex]

Step-by-step explanation:

Substitute the x-value of the vertex for a, and the y-value of the co-vertex for b in the standard equation of a horizontal ellipse [tex]\frac{x^{2} }{a^{2}} +\frac{y^{2}}{b^{2}} =1[/tex].

[tex]\frac{x^{2} }{a^{2}} +\frac{y^{2}}{b^{2} } =1[/tex]  

[tex]\frac{x^{2} }{-3^{2}} +\frac{y^{2} }{2^{2} } =1[/tex]

[tex]\frac{x^{2} }{9 } +\frac{y^{2} }{4} } =1[/tex]

Answer:

x - 8 = 0

Step-by-step explanation:

Since, the cube root of a number is 2.

Let the number be x.

Therefore,

[tex] \sqrt[3]{x} = 2 \\ cubing \: both \: sides \\ {( \sqrt[3]{x})}^{3} = {(2)}^{3} \\ x = 8 \\ x - 8 = 0[/tex]

Answer:

? measures (13 - 9) or 4 yards

Step-by-step explanation:

Answer:

B and C

Step-by-step explanation:

Not A because the side lengths aren't multiples.

Not D because it would be congruent, unless it had different angles, but then similar shaps must have the same angles

The answer is, X = 12.

hope it helps.

Answer:

x = 12

Step-by-step explanation:

simlify 4/3 * (3x-12)

4x - 16 = 2x + 8

combine like terms, so subtract 2x by 4x

2x - 16= 8

then finish combining like terms, so 16 plus 8

2x = 24

divide 24 by 2

x = 12

Answer:

5x(f+9g)

Step-by-step explanation:

5xf(1)+5xg(9)

Factor out 5.

5(xf+9xg)

Consider xf+9xg. Factor out x.

x(f+9g)

Rewrite the complete factored expression.

5x(f+9g)

Graph if needed:

The surface area of the cone is 16π square units.

The surface area of the cone is given by;

⇒ Area = πrl + πr²

Here, We have;

A right cone has a slant height of 6 and a radius of 2.

Substitute all the values in the formula

⇒ Area = πrl + πr²

⇒ Area = π x 2 x 6 + π x 2²

⇒ Area = 16π

Hence, The surface area of the cone is 16π square units.

Answer:

Talia needs to factor -1 out of one of the two binomials

Step-by-step explanation:

She could take:

3x(5x - 1) + 4(-5x + 1)

and rewrite it as:

3x(5x - 1) - 4(5x - 1)

= (3x - 4)(5x - 1)

Answer:

The answere is C.

Step-by-step explanation:

It is right on edge

Answer:

Usually reactions speed up with increasing temperature. Physical state of reactants. Powders react faster than blocks - greater surface area and since the reaction occurs at the surface we get a faster rate. The presence (and concentration/physical form) of a catalyst (or inhibitor).
