Bess [88]

No more than in terms of math means less than or equal to.

P = 2l + 2w

{96 ≤ 2l + 2w

{L ≥ w - 4

Here we see a system of linear inequality in two variables.

You finish.

AfilCa [17]

22 quarters= $5.50
10 dimes= $1.00

$5.50 + $1.00 = $6.50
I just did trial and error. I started with 20 quarters and made changes until it worked.

When estimating the number of spheres contained in a prism we should account for the empty space between the spheres. To do this

Zielflug [23.3K]

Answer:

B. 8.0 cubic inches

Step-by-step explanation:

You need to find 190% of the volume of a gumball which is a sphere.

To find 190% of a quantity, multiply the quantity by 1.9.

volume of sphere = (4/3)(pi)(r^3)

diameter = d = 2 in.

radius = r = (1/2)d = (1/2)(2 in.) = 1 in.

volume of sphere = (4/3)(3.14159)(1 in.)^3 = 4.189 in.^3

The volume of a gumball is 4.189 in.^3

Now we need 190% of that volume.

190% of volume of sphere = 1.9 * volume = 1.9 * 4.189 in.^3 = 7.959 in.^3

Rounded to the nearest tenth, the volume is

B. 8.0 cubic inches

In a survey , rajveer asked 110 people whether they were employed or unemployed.

storchak [24]

Answer:

Step-by-step explanation:

Create a two-way table with the given information:

$\begin{array}{| c | c | c | c |}\cline{1-4} & \sf Employed & \sf Unemployed & \sf Total\\\cline{1-4} \sf Men & 40 & & 59 \\\cline{1-4} \sf Women & & & \\\cline{1-4} \sf Total & 84 & & 110 \\\cline{1-4} \end{array}$

Fill in the blanks in the table using <u>mathematical operations</u>:

⇒ Men unemployed = 59 - 40 = 19

⇒ Women employed = 84 - 40 = 44

⇒ Total women = 110 - 59 = 51

⇒ Total unemployed = 110 - 84 = 26

⇒ Women unemployed = 51 - 44 = 7

$\begin{array}{| c | c | c | c |}\cline{1-4} & \sf Employed & \sf Unemployed & \sf Total\\\cline{1-4} \sf Men & 40 & 19 & 59 \\\cline{1-4} \sf Women &44 & 7& 51 \\\cline{1-4} \sf Total & 84 &26 & 110 \\\cline{1-4} \end{array}$
