Answer:

27

Step-by-step explanation:

(30 workers/40 days) = (20 workers/x days) cross multiply

30*x=40*20 divide by 30 both sides

x= 800/30

x≈26.67

So they will need 27 days

Answer:

Angle 1 = 128

Angle 2 = 52

Angle 3 = 68

Angle 4 = 60

Angle 5 = 124

Step-by-step explanation:

Had to use supplementary theorem, vertical angles theorem, and that the angles of a triangle add up to 180.

I hope this helps!

Answer:

7/c

Step-by-step explanation:

7 divide by c is the same as 7/c

Slope formula - y = mx + b

6x + 2y = 10

subtract x

2y = 10 - 6x

divide all by 2

y = 5 - 3x

y = -3x + 5

5 is the y-intercept, and -3x is the slope

hope this helps :)

Answer:

1/4 equal pieces

Step-by-step explanation:

Total number of bowls of rice = 3

We are seeking servings of size 12

Then it means we are dividing 3bowls into 12 equal pieces

= 3/12 bowls

= 1/4 equal pieces

Which means each member of the family is getting 1/4 each of the bowl of rice

Therefore, 1/4 servings of size 12 can you make out of the 3 bowls of rice

Answer: 32w

Step-by-step explanation:

Answer:

2.12 seconds

Step-by-step explanation:

Given

[tex]h(t) = -16t^2 + 15t + 40[/tex]

Required

Determine how long the ball hits the ground

When the ball hits the ground means that [tex]h(t) = 0[/tex]

So, we have that:

[tex]h(t) = -16t^2 + 15t + 40[/tex] becomes

[tex]0 = -16t^2 + 15t + 40[/tex]

Reorder

[tex]-16t^2 + 15t + 40 = 0[/tex]

Multiply through by -1

[tex]16t^2 - 15t - 40 = 0[/tex]

Solve using quadratic:

[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]

Where

[tex]a = 16[/tex] [tex]b = -15[/tex] [tex]c = -40[/tex]

So, we have:

[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex] becomes

[tex]t = \frac{-(-15)\±\sqrt{(-15)^2 - 4*16*-40}}{2*16}[/tex]

[tex]t = \frac{15\±\sqrt{(-15)^2 - 4*16*-40}}{2*16}[/tex]

[tex]t = \frac{15\±\sqrt{225 +2560}}{32}[/tex]

[tex]t = \frac{15\±\sqrt{2785}}{32}[/tex]

[tex]t = \frac{15\±52.77}{32}[/tex]

Split:

[tex]t = \frac{15+52.77}{32}[/tex] or [tex]t = \frac{15-52.77}{32}[/tex]

[tex]t = \frac{67.77}{32}[/tex] or [tex]t = \frac{-37.77}{32}[/tex]

[tex]t = 2.12[/tex] or [tex]t = -1.18[/tex]

But time can't be negative

So:

[tex]t = 2.12[/tex]

Hence, time to hit the ground is 2.12 seconds

Answer:

x = 120

Step-by-step explanation:

x/12 - 9 = 1

Inverse operations

x/12 - 9 = 1

Answer:

for the second question , all you have to do is substitute , the first point plotted is x and the second point is b , ploy those points in the equation and remember that to find x we make y= 0 and to find y we make x =0

Answer:

The three integers are

11, 13, and 15.

Step-by-step explanation:

. The sum of these is 39, so we can write:

x+(x+2)+(x+4)=39

Open the brackets and simplify.

x+x+2+x=+4=39

3x+6=39

Subtract 6 from each side.

3x=33

Divide both sides by 3.

x=11

Therefore: (x+2)=13 and (x+4)=15

Answer:

y-6=-6(x-1)

Step-by-step explanation:

Hope this helps :D

have a nice thanksgiving

Answer:

[tex]y-6=-6(x-1)[/tex]

Step-by-step explanation:

A point-slope equation requires two values in order to write it: one coordinate and the slope.

First, find the slope between the two given points. To find the slope, you would subtract the first Y from the second Y and the first X from the second X. Y goes on top of the fraction bar, making the equation look like this:

[tex]\frac{6-(-6)}{1-3}[/tex]

Then, simplify the slope equation:

[tex]\frac{6-(-6)}{1-3} = \frac{6+6}{1-3} = \frac{12}{-2} = -6[/tex]

The slope is -6.

Finally, choose one of the coordinates. For this, I'll pick (1, 6).

The point-slope equation is [tex]y-y_{1} =m(x-x_{1})[/tex]

So, simply fill in the [tex]m[/tex], [tex]y_{1}[/tex] , and [tex]x_{1}[/tex] spots with the value we have found.

[tex]m[/tex] is the slope, so replace it with -6.

[tex]y_{1}[/tex] = 6

[tex]x_{1}[/tex] = 1

Final answer:

[tex]y-6=-6(x-1)[/tex]

Answer:

y=2x-2

Step-by-step explanation:

my work is in the picture I attached. lmk if you'd like me to explain more

Answer:

y = 2x - 2

Step-by-step explanation:

let equation of the line be y = mx + c

since it is parallel to y = 2x + 2, gradient/slope of the two lines would be the same

therefore, m = 2

since it passes through (4, 6),

sub (4, 6):

6 = 2(4) + c

c = -2

therefore equation of the line is y = 2x - 2

Answer:

Step-by-step explanation:

I = prt

I = 800 × 1.8% x 15

I = $216

Remember the percent sign for the rate or write it as a decimal (multiplier)! In this case the multiplier would be 0.018!

Hope this helps, please mark as brainliest! :)

Answer: 64 ; $28

Step-by-step explanation:

A. Billy collected 256 conks but lost ¾ of them on his way to school through a hole in his bag. When he arrived at school how many conks did Billy had left?

Number of conks collected by Billy = 256

Fraction lost = 3/4

Amount lost = 3/4 × 256 = 192

Number of conks Billy has left will be:

= 256 - 192

= 64

B. Skateboards cost €36 each in my local store. The shopkeeper says if I buy one I can buy another for only 7/9 of the normal price. How much would a second skateboard cost?

This will cost:

= 7/9 × $36

= 7 × $4

= $28

Answer:

false

Step-by-step explanation:

Answer:

False, it has no solution if the lines are parallel.

Answer:

455

Step-by-step explanation:

900-(35×13)=455

Answer:

-9

Step-by-step explanation:

x + 109 + x + 89 = 180° because these angles are supplementary

2x + 198 = 180 subtract 198 from both sides

2x = - 18 divide by 2

x = -9
