Maggie combines 8.27 ounces of strawberries with 6.65 ounces of blueberries to make fruit bowls. She pours the fruit equally into 2 bowls, and has 1.56 ounces of fruit left over. How many ounces of fruit are in each bowl
Answers
Answer:
6.68 ounces
Step-by-step explanation:
Maggie combines 8.27 ounces of strawberries and 6.65 ounces of blueberries to make a fruit bowl
= 8.27 + 6.65
= 14.91 ounces
She will have 1.56 ounces left over
= 14.91-1.56
= 13.36 ounces
Therefore the number of ounces in each fruit bowl can be calculated as follows
= 13.36/2
= 6.68 ounces

The ratio between the number of red and green marbles in a box is 3:7. How many marbles are in the box if there are 20 fewer red marbles than green marbles?
I need this ASAP!
Answers
Answer:
50 marbles
Step-by-step explanation: The difference between the ratio of the red and green marbles is 4 units and the number value is 20 so its safe to say that 4 units is equal to 20 and thus one unit is 5 and because of the fact that there is a total of 10 units of marbles in the box according to the ratio, just multiply 5 and 10 which you get 50.
4 units = 20
1 unit = 20÷4 = 5
Total = 10 units
10 unit = 5 ×10 = 50
Ans : 50 marbles

What is the equation of the line parallel to 8x−16y=−14 and passing through (3,0)?
6x−12y=18
6x+12y=18
12x−6y=−18
12x+6y=18
Answers
Answer:
2y = x - 3
Step-by-step explanation:
Parallel lines can be defined as lines that do not intersect and as a result of this, parallel lines have the same slope but different intercepts.
Given the following data;
Points (x, y) = (3, 0)
Equation is 8x - 16y = -14
To find the equation of the line?
First of all, we would have to determine the slope of the line;
y = mx + c ......equation 1
8x - 16y = -14
Rearranging the equation, we have
16y = 8x + 14
Dividing through by 16, we have;
y = 8/16(x) + 14/16
y = 1/2(x) + 7/8
Therefore, the slope, m is 1/2
*To find the intercept*
Since the line is parallel we would use, m = 1/2
Substituting the values into equation 1, we have;
y = mx + c for x = 3 and y = 0
0 = 1/2(3) + c
c = -3/2
Re-writing the equation of line;
Slope, m = 1/2
Intercept, c = -3/2
y = 1/2(x) + (-3/2)
Multiplying all through by the lowest common denominator "2"
2y = x - 3

Option B,C and E are solution to given inequality [tex]y - 3x < -8[/tex]
Step-by-step explanation:
We need to check which ordered pairs from given options satisfy the inequality [tex]y - 3x < -8[/tex]
Ordered pairs are solutions to inequality if they satisfy the inequality
Checking each options by pitting values of x and y in given inequality
A ) (1, -5)
[tex]-5-3(1)<-8\\-5-3<-8\\-8 < -8 \ (incorrect)[/tex]
So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.
B) (-3, - 2)
[tex]-2-3(-3) < -8\\-2-9<-8\\-11 < -8 (true)[/tex]
So, this ordered pair is solution of inequality as it satisfies the inequality.
C) (0, -9)
[tex]-9-3(0)<-8\\-9-0<-8\\-9<-8 \ (true)[/tex]
So, this ordered pair is solution of inequality as it satisfies the inequality.
D) (2, -1)
[tex]-1-3(2)<-8\\-1-6<-8\\-7<-8 \ (false)[/tex]
So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.
E) (5, 4)
[tex]4-3(5)<-8\\4-15<-8\\-11<-8 \ (true)[/tex]
So, this ordered pair is solution of inequality as it satisfies the inequality.
So, Option B,C and E are solution to given inequality [tex]y - 3x < -8[/tex]
A rocket is launched from a tower the height of the rocket why in feet is related to the time after launch X in seconds by the given equation use this equation find the maximum height reached by the rocket to the nearest 10th of a foot y=-16x^2+152x+83
Answers
Answer:
444mStep-by-step explanation:
Given the height of the rocket modelled by the equation;
y=-16x^2+152x+83
The rocket reaches its maximum height when the velocity of the rocket is zero.
Since velocity is the change in displacement with respect to time;
velocity v = dy/dx
dy/dx = -32x + 152
at dy/dx = 0
-32x + 152 = 0
-32x = -152
x = -152/-32
x = 4.75s
To get maximum height reached by the ball, we will substitute x = 4.75 into the modeled function as shown;
y(4.75) = -16(4.75)^2+152(4.75)+83
y(4.75) = -361+722+83
y(4.75) = 444m
Hence the maximum height reached by the ball is 444m

Answers
Answer: 3/11
Step-by-step explanation:
Number of purple marbles = 6
Number of blue marbles = 5
Total number of marbles = 6 + 5 = 11
The probability of picking the dust purple marble will be 6/11. After a purple marvel has been picked, there'll be 5 purple marbles left and the total number of marbles will be 10, therefore the probability of picking the second purple marble will be 5/10.
Therefore we then multiply the probability of picking the first purple marble by the probability of picking the second purple marble. This will be:
= 6/11 × 5/10
= 6/11 × 1/2
= 3/11

Find the ordered pairs for the x- and y-intercepts of the equation 2x − 6y = 24 and select the appropriate option below. (5 points) Group of answer choices The x-intercept is (2, 0); the y-intercept is (0, –6). The x-intercept is (0, 2); the y-intercept is (–6, 0). The x-intercept is (12, 0); the y-intercept is (0, –4). The x-intercept is (0, 12); the y-intercept is (–4, 0).
Answers
Answer: C
Step-by-step explanation:
The x-intercept is found when y=0, and the y-intercept is found when x=0. If y=0, then we have:
2x=24
x=12
Therefore, the x-intercept is 12, so the full coordinates are (12, 0). Note that the only option with this x-intercept is C, so C is the correct answer.
You can find the y-intercept similarly. If x is zero, then:
-6y=24
y=-4
Therefore, (0, -4) is the y-intercept.

Answer:
see below
Step-by-step explanation:
Read the words down to the point where it says "graph this equation." Then, it's not a word problem anymore—it's a problem of graphing the given equation.
c = 2t +8
The "y-intercept" is the value of "y" when t=0. It is 8. This is the cost of a pizza with 0 toppings.
The slope is the coefficient of t. It is 2. This is the increase in the cost of a pizza when 1 topping is added. The slope is the cost of a topping.
__
Be aware that the grid on this graph shows squares, but the vertical dimension of the square is $2 while the horizontal dimension is 1 topping. That is, a line with a slope of 2 will lie on the diagonal of a grid square.
_____
Additional comment
We call the point where the graph crosses the vertical axis the "y-intercept." It is called that here, even though "y" is not in the equation or on the graph anywhere. It should rightfully be called the "c-intercept", since the vertical axis shows the value of c, the cost of the pizza.

You baked ¾ of a cake in 5/6 of an hour. How long will it take you to bake 18 cakes?
Answers
Answer:
20 hours
Step-by-step explanation:
First, it would be easiest to find how long it will take to bake 1 cake. We can take 5/6 and multiply it by 100 to put it into a percentage form. Then we divide by 75 (3/4 is 75%). This gives us 1.11 hours to bake 1 cake. We then multiply 1.11 by 18 (for 18 cakes) and our final answer is 20 hours to bake 18 cakes.
