Juanita is bringing the snacks for her daughter’s soccer team. Each girl on the team will eat 1/3 of an orange and drink one serving of juice or 1/9 of the amount in a bottle. How many oranges and how many juice bottles will she need for all 18 girls?show you work!!
Answer:
6 Oranges and 2 bottles of juice.
Step-by-step explanation:
For the amount of oranges: 18÷3=6 (take 1/3 of 18).
For the bottles of of Juice: 18÷9=2 (take 1/9 of 18).
in this question, if the numerator is 1, then just divide the number of girls by the denominator (eg. 3 and 9 in this case).
There are six oranges and two bottles of juice will she needs for all 18 girls.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
For example 4/2 = 2
There are the total number of girls is 18. Each girl will eat 1/3 of an orange and one serving of juice, or 1/9 of the amount in a bottle.
To determine the number of oranges and the bottles of juice.
We have to divide the number of girls by the denominator (eg. 3 and 9 in this case).
For the number of oranges:
1/3 of 18
18 ÷ 3
18 / 3 = 6
For the bottles of Juice:
1/9 of 18
18 ÷ 9
18 / 9 = 2
Hence, there are six oranges and two bottles of juice will she needs for all 18 girls.

how do you solve 8x-3y=-70 and -2x+5y=-8 using the elimination method please show work.
Answer:
6x+2y=-78
Step-by-step explanation:
8x-3y=-70
-2x+5y=-8
6x+2y=-78
Answer:
(-11, -6).
Step-by-step explanation:
8x-3y=-70
-2x+5y=-8 Multiply this equation by 4:
-8x+20y=-32
Now add this last equation to the first equation:
17y = -102 - we see that we have eliminated x.
y = -102/17
= -6.
Now plug y=-6 in the first equation to get x:
8x-3(-6)=-70
8x =-70 -18
8x =-88
x = -11.

Answer:
AB = sqrt 74 = 8.602
Step-by-step explanation:
simple:
a^2+b^2=c^2
5^2+7^2=74
ab=sqrt 74
Formula :
Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2
Solution :
Distance between two points = √(8−3)2+(2−9)2(8-3)2+(2-9)2
= √52+(−7)252+(-7)2
= √25+4925+49
= √7474 = 8.6023
Distance between points (3, 9) and (8, 2) is 8.6023

the straight line L has an equation y=1/2x+7. The straight line m is parallel to L and passes through the point (0,3). Write down an equation for the line M.
Answer:
y = x + 3
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 )
y = x + 7 ← is in slope- intercept form
with slope m =
Parallel lines have equal slopes
line M crosses the y- axis at (0, 3) ⇒ c = 3
y = x + 3 ← equation of line M

A store buys 200 shirts at the cost of 1,600$ and sells them at 10$ . What the percent markup
Answer:
25% markup
Step-by-step explanation:
they bought 200 shirts for 1600, which is 8$ per shirt
if they sell then at 10$ they get 2 dollars profit.
if you do 2/8 you get 25%
Also 1/4 of 8$ is 2$ and that is what your profit is.
Answer:
25%
Step-by-step explanation:
Cost of one short:
1600 : 200 = $8
8 + 8(x/100)= 10
800 + 8x= 1000
8x = 200
x = 25 %

Step-by-step explanation:
Find the number of ways you can arrange (a) all of the letters and (b) two of the letters in the word TRY. a. The number of ways you can arrange all of the letters in the word is __. b. The number of ways you can arrange two is the letters in the word is __.
Answer:
a) 6 ways
b) 6 ways
Step-by-step explanation:
a) for all of the letters
for the first letter, we have 3 options
for the second, we have 2 options
for the third, we have 1 option
So the number of options will be;
3 * 2 * 1 = 6
b) for the first, we have 3 options, for the second, we have 2 options
so the number of options will be 3 * 2 = 6 options

Is a parabola a one-to-one function?
Answer:
no
Step-by-step explanation:
The function f(x)=x2 is not one-to-one because f(2) = f(-2). Its graph is a parabola, and many horizontal lines cut the parabola twice. The function f(x)=x 3, on the other hand, IS one-to-one. If two real numbers have the same cube, they are equal.

Answer:

Step-by-step explanation:
1. A signal tower has two lights that are 30 feet apart from each other, one directly above the other. From
a boat, the angle of elevation of the lower light is 14 degrees, and the angle of elevation yo the upper
light is measured to be 32 degrees.
a) Find to the nearest foot the distance from the boat to the lower light.
b) The boat and the foot of the tower are in the same horizontal plane. Find to the nearest foot the
distance from the boat to the foot of the tower.
Solution :
It is given that the distance between the two lights is 30 feet.
The angle of elevation of the upper light from the boat, ∠ ABP = 32 degree
The angle of elevation of the lower light from the boat, ∠ ABQ = 14 degree
∴ ∠ PBQ = ∠ ABP - ∠ ABQ
= 32 - 14
= 18 degree
In triangle PAB
∠ PAB = 180 - (90 + 32)
= 58 degree
Similarly in triangle AQB
∠ AQB = 180 - (90 + 14)
= 76 degree
Now considering triangle PBQ and applying the sine theorem,
[tex]$\frac{PQ}{\sin 18}=\frac{BQ}{\sin 58}$[/tex]
we know PQ = 30 feet
∴ [tex]$BQ =\frac{\sin 58}{\sin 18} \times 30$[/tex]
= 82.33 feet
Again taking the right triangle ABQ and applying sine theorem,
[tex]$\frac{BQ}{\sin 90}=\frac{AB}{\sin 76}$[/tex]
[tex]$\frac{82.33}{\sin 90}=\frac{AB}{\sin 76}$[/tex]
∴ [tex]$AB = 82.33 \times \sin 76$[/tex]
= 79.88 ft
= 80 feet
