Answer:

Step-by-step explanation:

Let the relation between the total number of candies (y) and number of bags (x) is,

y = mx + b

Here, b = Extra pieces of candies sitting outside the box.

m = Candies per box

From the question,

x = 4,(Number of bags are 4)

y = 4m + 4

If total number of candies are 36,

36 = 4m + 4

4m = 32

m = 8

Each bag will contain 8 candies.

Therefore, equation representing the relation is,

y = 8x + 4

Now complete the table by substituting the values of x,

x y

. Suppose you plan to make a box that will hold exactly 40 one-inch cubes. Give the dimensions (ex: 1in x 1in x 40in) of 3 possi

stiks02 [169]

Answer:

The dimensions of the three possible boxes are;

Box 1: 2 inches length by 4 inches width by 5 inches height

Box 2: 2 inches length by 2 inches width by 10 inches height

Box 3: 8 inches length by 1 inch width by 5 inches height

Step-by-step explanation:

The dimensions of the required box = 40 in³

Therefore, a box that will hold all the cubes will have a dimension given as follows;

Length, l × Width, w × Height, h = 40 in.³

We therefore, look for possible dimensions of l, w, h, however to make is faster, we note that l × w = base area, BA, hence we look for the factors 40 thus;

BA × h ≡ l × w × h

8 × 5 = 40 ≡ 2 × 4 × 5 = 40

4 × 10 = 40 ≡ 2 × 2 × 10 = 40

8 × 5 = 40 ≡ 8 × 1 × 5 = 40

Hence we have our three possible boxes as follows;

Box 1: Length = 2 inches, width = 4 inches and height = 5 inches

Box 2: Length = 2 inches, width = 2 inches and height = 10 inches

Box 3: Length = 8 inches, width = 1 inches and height = 5 inches.

Labor economists have extensively researched the determinants of earnings. Invest-ment in human capital, measured in years of ed

never [62]

Answer:

Kindly check explanation for other solutions

Years, Inning and saves are statistically significant ; ERA is not.

Step-by-step explanation:

Earning for staying one additional year :

Multiply slope value of years * 1 = 0.052 * 1 * 100 % = 5.2% (earning increases by 5.2%)

Relives with 10 more saves :

10 * 0.0032 * 100% = 3.2% (earning increases by 3.2%)

Having 100 more innings :

100 * 0.00089 * 100% = 8.9%

If ERA is reduced by 1.5 ; earning will increase by (0.0085*100)% * 1.5 = 1.275%

B.) At 5% level of confidence :

α = 1.64

Years = 0.052/0.026=2

Inning = 0.00089/0.00020 = 4.45

Saves = 0.0032/0.0018 = 1.78

ERA = 0.0085/0.0168 = 0.51

Years, Inning and saves are statistically significant as they are greater than α ; As for ERA, it is not statistically significant (0.51 < 1.64)

If g(x)= x+1/x-2 and h(x)=4-x, what is the value of (g times h)(-3)

Alchen [17]

$g(-3)=\frac{-3+1}{-3-2}=\frac{2}{5} \\ \\ h(-3)=4-(-3)=7 \\ \\ (g\times h)(-3)=7\left(\frac{2}{5} \right)=\boxed{\frac{14}{5}}$

Convert the percent to a decimal

Zanzabum

Answer:

40.0

18%

14.375%

1/250

6325

Step-by-step explanation:

Convert the percent to a decimal 4,000%

4000% = 4000/100 = 40.0

Convert the decimal or whole number to a percent.

0.36 * 1/2

= 0.36/2 * 100

= 0.18 * 100

= 18%

Convert the decimal or whole number to a percent.

1.15 * 1/8

= 1.15/8 * 100

= 14.375%

Convert the percent to a reduced fraction, mixed number, or whole number.

0.4%

= 0.4/100

= 1/250

Solve for the portion (in $). Round to hundredths when necessary.

9 1/2% of $400 = 19/2% x 400

= 0.095 x 400

= 38

Solve for the portion. Round to hundredths when necessary.

What number is 253% of 2,500?

253/100 x 2500

= 2.53 x 2500

= 6325

Find the value of x

hodyreva [135]

To find the value of x, compare the equal sides, As two angles are equal so the sides opposite to these angles are also equal.
Compare the sides.
9x-8=28
Add 8 to both sides
9x=36
Divide both sides by 9.
x=4

Answer: x=4
