Answer:

the number of dozen cookies donated altogether is [tex]7\frac{3}{4}[/tex]

Step-by-step explanation:

Given that

The store donated 4 1 ÷ 2 dozen cookies

And, the another store donated 3 1 ÷ 4 dozen cookies

we need to find oyt the no of dozen cookies donated altogether is

[tex]= 4 \frac{1}{2} + 3 \frac{1}{4} \\\\= \frac{9}{2} + \frac{13}{4} \\\\= \frac{18 + 13}{4} \\\\= \frac{31}{4}\\\\= 7\frac{3}{4}[/tex]

Hence, the number of dozen cookies donated altogether is [tex]7\frac{3}{4}[/tex]

Answer:1407.4 rounded to nearest tenth

Step-by-step explanation:

Answer:

Heather served 10 orders.

Felipe served 30 orders.

Jim served 50 orders.

What we know:

Let's refer to each person by their first initial (H, J, & F)

H + J + F = 90

F = 3 * H

J = 5 * H

Substitution:

Let's replace F and J by their equivalents in relation to H (basically making the entire left side only H)

H + (5 * H) + (3 * H) = 90

H + (5H) + (3H) = 90

9H = 90

H = 90/9

H = 10

Final Calculations

Now that we know how many orders Heather served, we can calculate how many Jim and Felipe served

F = 3 * H

F = 3 * 10

F = 30

J = 5 * H

J = 5 * 10

J = 50

Answer:

The equation of the circle is (x+3)^2 + (y-4)^2 = 16.

Step-by-step explanation:

The equation of a circle can be calculated if the center and the radius are known. The equation of a circle is given by  (x-h)² + (y-k)² = r²

Where  (h, k) = center coordinates  and r = radius.

Answer

[tex]300 \geqslant 22.5x + 200[/tex]

Step-by-step explanation:

300 is less than or equal to 22.5x + 200

the budget is 300 so you can't go past that number. the appropriate inequality sign for this would be less than or equal to the following equation: $22.5 x (where x= number of hours) + the fixed fee of $200

don't include $ (or other units of measurements) in equations!!

Given:

Consider the below picture attached with this question.

The given expression is:

[tex]\dfrac{9m^2}{3m}-\dfrac{4m}{3m}-\dfrac{6}{3m}[/tex]

To find:

The next step.

Solution:

We have,

[tex]\dfrac{9m^2}{3m}-\dfrac{4m}{3m}-\dfrac{6}{3m}[/tex]

Cancel out the common factors.

[tex]=3m-\dfrac{4}{3}-\dfrac{2}{m}[/tex]

Therefore, the correct option is D.

Answer: 2,916 inches³

Step-by-step explanation:

The volume of a box is:

= Length * Width * Height

But all of these have to have the same units for it to work. This means that the height of the box will have to be converted to inches :

1 ft is 12 inches so:

= 1¹/₂ * 12

= 3/2 * 12

= 18 inches

Volume is therefore:

= 18 * 9 * 18

= 2,916 inches³

Step-by-step explanation:

Answer:

2x = 140  x = 70

Step-by-step explanation:

If you add the other 2 angles together, you get 150. Subtract 150 from 360 to get 210. Divide that by 3 and you get 70. Because QRS is 2 times the size of PQR, it is equal to 140.

Hope that this helps!

Explanation:

The sum of the interior angles of a quadrilateral is 360°.

x + 2x + 80 + 70 = 360

3x + 150 = 360

3x = 210

or

x = 70°

Therefore

angle Q = 70°

angle R = 2x = 140°
