Mr. Austin decided to make a healthy snack for the 20 students in his class. He gave each student a dish of yogurt and divided 6 cups of strawberries equally among the dishes.
How many cups of strawberries did each student get in their yogurt?
Write your answer as a proper fraction or mixed number.
Answer:
3/10 of a cup
Step-by-step explanation:
Find how many cups of strawberries each student got by dividing 6 by 20:
= 6/20
Simplify this by dividing each number by 2:
= 3/10
So, each student got 3/10 of a cup of strawberries
Find the intersection point between the lines of equations:
2x-y+6=0 and 2x+3y-6=0
Step-by-step explanation:
The two equation will intersect each other at the point which will be the solution of the given two equations , and the given equations are ,
[tex]\implies 2x -y +6=0\\\\\implies 2x + 3y -6=0[/tex]
On subtracting the given equations we have,
[tex]\implies -y - 3y +6 -(-6) = 0 \\\\\implies -4y = -12 \\\\\implies y = -12/-4\\\\\implies y = 3 [/tex]
Put this value in any equation , we have ,
[tex]\implies 2x -3 +6 =0\\\\\implies 2x = -3 \\\\\implies x =\dfrac{-3}{2} \\\\\implies x =-1.5 [/tex]
Hence the lines will Intersect at ,
[tex]\implies\underline{\underline{ Point=(-1.5, 3)}}[/tex]
for the first one x = 1/2 y-3" and y = 2 x + 6 and for the other one is x = − 3 /2 y+ 3 and y= − 2 /3 x + 2
how i did this Step 1: Add -3y to both sides.
Step 2: Add 6 to both sides.
Step 3: Divide both sides by 2.

Calculate the average rate of change of a function over a specified interval. Which expression can be used to determine the average rate of change in f(x) over the interval 2, 9?
Given:
The interval is [2,9].
To find:
The average rate of change in f(x) over the interval [2,9].
Solution:
The average rate of change in f(x) over the interval [a,b] is defined as:
[tex]m=\dfrac{f(b)-f(a)}{b-a}[/tex]
In the interval [2,9], the value of a is 2 and the value of b is 9.
Using the above formula, the average rate of change in f(x) over the interval [2,9] is:
[tex]m=\dfrac{f(9)-f(2)}{9-2}[/tex]
[tex]m=\dfrac{f(9)-f(2)}{7}[/tex]
Therefore, the required expression for the average rate of change in f(x) over the interval [2,9] is [tex]\dfrac{f(9)-f(2)}{9-2}[/tex], it is also written is [tex]\dfrac{f(9)-f(2)}{7}[/tex].

the first day she walked 27 kilometers. each day since she walked 2/3 of what she walked the day before. what is the total distance cecelia has traveled be the end of the 5th day?
Answer: 70
Step-by-step explanation:
We are required to calculate the total distance Cecilia travelled in 5 days
The total distance Cecilia travelled for 5 days is 99 kilometers
Day 1 = 27 kilometers
Day 2 to day 5 = 2/3 of 27
= 2/3 × 27
= 2 × 9
= 18 kilometers each day
Total distance = day 1 + day 2 + day 3 + day 4 + day 5
= (27 + 18 + 18 + 18 + 18) kilometers
= 99 kilometers
Therefore, the total distance Cecilia travelled for 5 days = 99 kilometers

The functionſ is defined by f(x) = x(x + 3). If f(a) = 40 and a > 0, what is the value of a ?
A) 3
B) 5
C) 7
D) 8
Answer:
B) 5
Step-by-step explanation:
We are given the function:
[tex]f(x)=x(x+3)[/tex]
We are given that f(a) = 40 and a > 0 and we want to determine the value of a.
Substitute:
[tex]f(a)=40=a(a+3)[/tex]
Distribute:
[tex]a^2+3a=40[/tex]
Subtract 40 from both sides:
[tex]a^2+3a-40=0[/tex]
We can factor using 8 and -5. Hence:
[tex](a+8)(a-5)=0[/tex]
By the Zero Product Property:
[tex]a+8=0\text{ or } a-5=0[/tex]
Solve for each case:
[tex]\displaystyle a=-8\text{ or } a=5[/tex]
Since a > 0, we can eliminate the first solution. Hence:
[tex]a=5[/tex]

Answer:
Step-by-step explanation:
This is a right triangle because angle V is 90. Draw out a right triangle and put V at the 90 degree angle. It doesn't matter where you put U or T; you get the same cos value for T regardless of how you place your other 2 angles. The things you need to know are that UT is the hypotenuse of the triangle, side VU is across from angle T, and side TV is across from angle U.
The cos ratio is side adjacent to the reference angle over the hypotenuse.
Our reference angle is T, so we are looking for the side next to T that is NOT the hypotenuse. This side measures 33; the hypotenuse measures 65, so the tangent ratio of T is
[tex]tanT=\frac{33}{65}[/tex]
The equation of a line is 2(y + 1) = 10x + 3.
The y-intercept of the line is
, and the slope of the line is
Answer:
y intercept is (0,-0.5) and the slope is 5.
Step-by-step explanation:
Let's rewrite the equation in slope intercept form.
Step 1: divide both sides by two:
[tex]\frac{2\left(y+1\right)}{2}=\frac{10x}{2}+\frac{3}{2}[/tex]
Step 2: simplify [tex]y+1=\frac{10x+3}{2}[/tex]
Step 3: subtract one from both sides: [tex]y+1-1=\frac{10x+3}{2}-1[/tex]
[tex]y=\frac{10x+3}{2}-1[/tex]
[tex]y = 5x - \frac{1}{2}[/tex]

A cylinder has a volume of 245x cubic units and a helght of 5 units. The diameter of the cylinder is
7 units
14 units
49 units
Answer:
Diameter = 14 units
Step-by-step explanation:
Volume ofa cylinder = πr²h
Volume of the cylinder = 245π cubic units
Height = 5 units
Volume of a cylinder = πr²h
245π = π × r² × 5
245π = 5r²π
Divide both sides by π
245π / π = 5r²π / π
245 = 5r²
r² = 245/5
= 49
r² = 49
r = √49
r = 7 units
Diameter = 2 × radius
= 2 × 7 units
= 14 units
Diameter = 14 units

Step-by-step explanation:
1. draw the parallelogram with side 20cm and 25cm respectively and also the diagonal as well.
2.Clearly it forms a triangle in the parallelogram with three known lengths of side.
3.Using the cosine rule : c^2=b^2+c^2 -2bc cos c to find the obtuse angle.
9514 1404 393
Answer:
114.8°
Step-by-step explanation:
The angles can be found using the Law of Cosines. It tells you ...
c² = a² +b² -2ab·cos(C)
Then angle C can be found to be ...
C = arccos((a² +b² -c²)/(2ab)) = arccos((20² +25² -38²)/(2·20·25))
C = arccos(-419/1000) ≈ 114.77°
The measure of the obtuse angle is about 114.8°.
