52.5 days

Step-by-step explanation:

Ten people can dig 2 acres in 7 days.

One person can dig 0.2 acres in 7 days.

Working at half the rate, one person can dig 0.1 acre in 7 days.

8 people can dig 0.8 acres in 7 days.

8 people can dig 6/0.8 * 0.8 acres in 6/0.8 * 7 days.

8 people can dig 6 acres in 52.5 days

Step-by-step explanation:

i think thats right but sounds to easy

Answer:

t+3t=2-3+122

4t=121

divide both sides by four

4t/4=121/4

t=3.25

Answer:

t = 30.5

Step-by-step explanation:

t-122=[tex]\frac{3t}{2-3}[/tex]

t-122=-3t           (2-3=-1, so divide by -1 to get -3t)

4t=122

t=[tex]\frac{122}{4}[/tex]

t=30.5

Step-by-step explanation:

We see the triangle ABC and AED with common vertex at the point A.

1. The center of dilation is the point A as it remains unchanged after dilation and the other vertices are lined up with the point A.

2. Since the scale factor is 1/2 < 1, the dilation is a smaller triangle, which is AED

Answer:

A and C

Step-by-step explanation:

Answer:

a and c are right

Step-by-step explanation:

the base must be the number and the exponent is how many times it is multiplied

Answer:

Answer is c I think

Step-by-step explanation:

Answer:

positive (+)

Step-by-step explanation:

- × - = +

+ × - = -

+ × + = +

Answer:

there are 8 numbers, all are negetive and they are multiplied with each-other

we know, (-negative)(-nagative) = positive number

so even quantity of negative numbers multiplied with each-other makes a positive number.

so the sign of the product is +

Step-by-step explanation:

Answer:

19.0415

Step-by-step explanation:

Answer:

48,000

Step-by-step explanation:

The cost function by the given data is C(x) = 40,000 + 8x.

We are given that;

Monthly fixed cost = $40,000

The product cost for each unit produced= $8

Now,

The cost function is a function that gives the total cost of producing a certain number of units. The cost function depends on the fixed cost and the variable cost per unit. The fixed cost is the amount of money that the manufacturer has to pay regardless of how many units are produced, such as rent, salaries, utilities, etc. The variable cost per unit is the amount of money that the manufacturer has to pay for each unit produced, such as materials, labor, etc.

In this case, the fixed cost is $40,000 and the variable cost per unit is $8. To find the cost function, we need to add the fixed cost and the product of the variable cost per unit and the number of units.

We can use x to represent the number of units and C(x) to represent the cost function.

Then we have:

C(x) = fixed cost + (variable cost per unit)(number of units)

C(x) = 40,000 + (8)(x)

Therefore, by algebra the answer will be C(x) = 40,000 + 8x.

30 dogs are in the pound.

Step-by-step explanation:

If the original ratio is 9:6

Then multiply both sides by 5: (9*5) : (6*5)

New ratio: 45:30

Answer:

b ≤ 24

Step-by-step explanation:

Treat it like a two-step equation:

1/3b - 4 ≤ 4​

Add 4 on both sides: 1/3b - 4 (+4) ≤ 4​ (+4)

1/3b ≤ 8

Multiply 3 on both sides (3)1/3b ≤ 8(3)

b ≤ 24

Option A represents a integer

Answer:

1.152 x 10^9 gal/hr

Step-by-step explanation:

Given:

3.2 x 10^5 gal / 1 sec

1 hr = 3600 s

Convert:

[tex]\frac{3.2 x 10^5 gal}{1 sec} * \frac{3600 sec}{1 hr}[/tex]

By this, seconds cancel out leaving us with gal/hr, which is what we need.

= 1152000000

Scientific Notation: 1.152 x 10^9

Step-by-step explanation:

Answer:

5 or -8

Step-by-step explanation:

[tex](3 \times x) + x {}^{2} = 40[/tex]

[tex]3x + {x}^{2} = 40[/tex]

[tex] {x}^{2} + 3x - 40 = 0[/tex]

using factorization method

[tex]( {x}^{2} + 8x) ( - 5x - 40) = 0[/tex]

[tex]x(x + 8) - 5(x + 8) = 0[/tex]

[tex](x - 5)(x + 8) = 0[/tex]

[tex]x - 5 = 0[/tex]

or

[tex]x + 8 = 0[/tex]

[tex]x = 5[/tex]

or

[tex]x = - 8[/tex]
