Owen’s parents were planning a birthday party for him. They have $20.00 to spend on goodie bags. They need to buy 6 goodie bags at $2.49 each. Will Owen’s parents have enough money to buy all 6 goodie bags? I HAVE TO SHOW MY WORK
Answers
Answer:
Yes, they can buy all the bags.
Step-by-step explanation:
Owen's parents need to buy 6 bags for $2.49 each.
So, we need to calculate the total price:
$2.49 * 6 = $14.94
Since the bags cost $14.94, and Owen's parents have $20.00, they have enough money to buy all 6 bags. 14.94 < 20.00
Hope this helps!
Answer:
They will have enough money to spend on 6 goodie bags
Step-by-step explanation:
First, you need to mutiply $2.49 × 6 and then you get 14.94
then you need to subtract $20.00 - 14.94 to get $5.06
so your answer should be, ¨Owen´s parents will have $5.06 left after spending $14.94 of their $20.00 on goodie bags¨

In multiplication like this, the order doesn't matter:
5 * 3 = 15
3 * 5 = 15
2 * 9 = 18
9 * 2 = 18
Thus,
pq = p * q = q * p = qp

A shirt that you want to buy costs $15.50. You can use a $5 discount coupon if you spend at
least $20. Solve an inequality that represents how much more you must spend to use the $5
coupon.
(1 Point)
Answers
Answer: The answer is m= ≥4.50
The required inequality is m ≥ 4.50
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, A shirt that you want to buy costs $15.50. You can use a $5 discount coupon if you spend at least $20.
Cost of the shirt = $15.50
you can use a $5 discount coupon if you spend at least $20
The question requires you to find how much more you need to spend to be able to use the $5 discount coupon
The shirt already cost $15.50
Total amount you need to spend = $20
Let the amount remaining = m
m ≥ $20 - 15.50
m ≥ $4.50
Hence, you need to spend $4.50 in order to be able to use the $5 discount coupon.

The angles in a triangle are in the ratio 1:2:3. Show that this triangle is a right-angled triangle. The hypotenuse of the triangle is 19 cm long. Calculate the length of the shortest side in the triangle
Answers
Answer:
see explanation
Step-by-step explanation:
(a)
Sum the parts of the ratio , 1 + 2 + 3 = 6 parts
Divide sum of angles in a triangle by 6 to find the value of one part of the ratio.
180° ÷ 6 = 30° ← value of 1 part of the ratio
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
Since there is an angle of 90° then the triangle is right.
(b)
The shortest side is the side opposite the smallest angle of 30°
Using the sine ratio and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opp}{hyp}[/tex] = [tex]\frac{opp}{19}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2 opp = 19 ( divide both sides by 2 )
opp = 9,5
Shortest side in the triangle is 9.5 cm

B. y = - 4x + 28
OC. y= 3x-28
OD. y=x+28
Answers
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, 29) and (x₂, y₂ ) = (0, 28) ← 2 ordered pairs from the table
m = [tex]\frac{28-29}{0+4}[/tex] = - [tex]\frac{1}{4}[/tex]
The line crosses the y- axis at (0, 28 ) ⇒ c = 28
y = - [tex]\frac{1}{4}[/tex] x + 28 ← equation of line → D
Suppose the volume of a rectangular shopping cart basket is 12,090 cubic inches. If the length measures 31 inches and the width measures 19.5 inches, how high is the shopping cart basket?
Answers
Answer:
[tex]\boxed {\tt h=20\ inches}[/tex]
Step-by-step explanation:
The volume of a rectangular prism can be found using the following formula.
[tex]v=l*w*h[/tex]
We know that the volume is 12,090 cubic inches, the length is 31 inches, and the width is 19.5 inches.
[tex]v= 12,090 \ in^3\\l=31 \ in \\ w=19.5 \ in[/tex]
[tex]12,090 \ in^3= 31 \ in * 19.5 \ in * h[/tex]
Multiply 31 inches and 19.5 inches.
[tex]12,090 \ in^3= 604.5 \ in^2 * h[/tex]
We are trying to find h, therefore we must isolate it. h is being multiplied by 604.5 square inches. The inverse of multiplication is division. Divide both sides of the equation by 604.5 in²
[tex]\frac{12,090 \ in^3}{604.5 \ in^2}= \frac{604.5 \ in^2 *h}{604.5 \ in^2}[/tex]
[tex]\frac{12,090 \ in^3}{604.5 \ in^2}=h[/tex]
[tex]20 \ in =h[/tex]
The height of the shopping basket is 20 inches.
