QUICKK The Johnson family went to a socially distance movie and paid $30 for two adults and two children the modern family went to the same movie and paid 35 for two adults and three children what was the price of an adult ticket
Answers
Answer: adults = $10
Step-by-step explanation:
x = adults
y = children
2x + 2y = 30
2x + 3y = 35
Using the elimination method:
2x + 2y = 30
-2x - 3y = -35 (multiplied by -1, to give 2x -2x = 0)
Solve for y...
2y = 30
-3y = -35
Add together...
-y = -5
Multiply by -1 to give positive value for y...
y = $5
Plug into one of the original equation to find x...
2x + 10 = 30
2x = 20
x = $10

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.

A box measures 18 inches wide by 9 inches deep. The height of the box is 1 1/2 feet. What is the volume of the box? Remember if ft is equivalent to 12 in.
Answers
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
In rhombus ABCD shown below, AB=17 and AC=16 determine the length of BD without (hint , not with trigonometry)
Answers
Answer:
[tex]BD = 30[/tex]
Step-by-step explanation:
Given
[tex]AB = 17[/tex]
[tex]AC = 16[/tex]
See attachment
Required
Find BD
If AC = 16, then:
[tex]AO = 16/2[/tex] i.e. half the diagonal AC
[tex]AO = 8[/tex]
The diagonals of a rhombus are perpendicular.
This implies that we can apply Pythagoras theorem.
Using Pythagoras theorem on triangle AOB, we have:
[tex]AB^2 = AO^2 + OB^2[/tex]
[tex]17^2 = 8^2 + OB^2[/tex]
[tex]289 = 64 + OB^2[/tex]
Collect like terms
[tex]OB^2 = 289 - 64[/tex]
[tex]OB^2 = 225[/tex]
Take positive square roots of both sides
[tex]OB = 15[/tex]
To solve for BD, we use:
[tex]OB = \frac{BD}{2}[/tex] --- i.e. half the diagonal BD
[tex]BD = 2 * OB[/tex]
[tex]BD = 2 * 15[/tex]
[tex]BD = 30[/tex]

A store donated 4 ½ dozen cookies for a fundraiser. Another store donated 3 ¼ dozen cookies. How many dozen cookies did they donate altogether?
Answers
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]
