In a quiz consist of 10 questions,+2 marks are given for a correct answer, -1 marks for an incorrect answer and 0 marks for not attempting a question. Radhika got 8 correct answers and 2 wrong answers. What is her total score?
======================================================
Work Shown:
c = number of correct answers
w = number of wrong answers
n = number of questions not attempted
2c = points you get from all the correct answers
-1w = points you get from all the wrong answers
0n = points you get from all the questions attempted
2c-1w+0n = 2c-w = total number of points
In this case, she got 8 correct answers and 2 wrong answers. So c = 8 and w = 2 which leads to
2c-w = 2*8-2 = 16-2 = 14
Her total score is 14.
which ordered pair is the solution to y=x+2/5
Answer: (2, 2 )
Step-by-step explanation:
Plug the x and y-values into the given equation. If it makes a true statement, then it is a solution.
y = x +
(0,0) → 0 = 0 + FALSE
(1, ) → = 1 + FALSE
(2, 2 ) → 2 = 2 + TRUE

-7(n+2)=-14-7n how many solution does it have
Answer:
There is an infinite number of solutions.
Step-by-step explanation:
When you simplify the left side of the equation, you get -7n - 14, which is equal to the right side. If you were to plug in any number for n, it will equal the same on both sides of the equation.
Victor is making recipes for smoothies. His first recipe calls for 2 cups of strawberries and 7 cups of other ingredients. His second recipe says that 3 cups of strawberries are combined with 9 cups of other ingredients. Which smoothie recipe has more strawberries compared to other ingredients?
Answer:
The second smoothie recipe has more strawberries compared to other ingredients
Step-by-step explanation:
Recipe 1:
2 cups of strawberries : 7 cups of other ingredients
= 2/7
= 0.29
Recipe 2:
3 cups of strawberries : 9 cups of other ingredients.
= 3/9
= 1/3
= 0.33
The second smoothie recipe has more strawberries compared to other ingredients

Angelina put 3,000 milliliters of water in a tub that already has 5 liters of water in it. Jack says the
tub now has 35 liters of water in it. Angelina says he is wrong.
Carry out your steps. Explain who is correct and why.
Answer:
Jack is wrong because 3,000 milliliters is equal to 3 liters. If the tub already has 5 liters in it, adding 3 liters makes the tub have 8,000 liters. Angelina is correct when she says Jack is wrong.

Answer:
800 blue marbles
Step-by-step explanation:
Since the ratio of red to blue is 3 to 4, we know that there is 600 red marbles.
Using this information we know that 3 and 600 are both red marbles, now we multiply 3 by 200 to get a total of 600 red marbles. You can also find the value needed to multiply the 3 by dividing 600 by 3.
Since we know that 1 ratio is 200, we multiply 4 by 200 to get 800 blue marbles.

5x+2y=10
Solve for y
Answer: y=(-5x/2)+5
Step-by-step explanation:
There is no clear cut explanation for this. y cannot directly equal a number. Let me show you.
Subtract 5x from both sides.
5x-5x+2y=10-5x
2y=-5x+10
Then to get to y to being by itself, divide by 2 on both sides
(2y/2)=(-5x+10)/2
y=(-5x+10)/2----> or -5x/2 + 10/2
y=(-5x/2)+5

Some farmers use a circular irrigation method. An irrigation arm acts as the radius of an irrigation circle. How much land is covered with an irrigation arm of 370 ft?
The land that is covered with an irrigation arm of 370 ft is
Answer:
The land that is covered with an irrigation arm of 370 ft is [tex]430,084\ ft^2[/tex]
Step-by-step explanation:
Area of the circle
Being r the radius of a circle, its area can be calculated as follows:
[tex]A=\pi\cdot r^2[/tex]
The irrigation arm acts as the radius of the irrigation circle, thus r=370 ft. The land covered is the area under the irrigation arm, thus:
[tex]A=\pi\cdot 370^2[/tex]
[tex]A=430,084\ ft^2[/tex]
The land that is covered with an irrigation arm of 370 ft is [tex]430,084\ ft^2[/tex]
After Megan walked 5 miles, her activity tracker had counted 9,780 steps. David's activity tracker had counted 11,928 steps after he walked 6 miles. Suppose each person's step covers about the same distance. Who takes more steps to walk 1 mile? How many more steps?
Answer:
The answer is below
Step-by-step explanation:
Meghan covered 5 miles with 9,780 steps. The number of steps per mile = 9780 / 5 = 1956 steps per mile
David covered 6 miles with 9,780 steps. The number of steps per mile = 11928 / 6 = 1988 steps per mile
This means that David covered more steps per mile compare to Meghan. The number of more steps = 1988 - 1956 = 32
Therefore David had 32 more steps per mile
If m_3 = 29°, what is m_4?
0
m_4 =
Answer:
151°
Step-by-step explanation:
angle m_3 and m_4 must add up to 180 because they both lie on a straight line. Thus, we can do 180-29 to get m_4.

Maggie‘s brother is 11 years younger than four times her age. The sum of their ages is 54. How old is Maggie?
Answer:
Maggie is 13
Step-by-step explanation:
Honestly, I just kept trying ages starting from 10 because I knew it wasn't going to be less than that. Then I did whatever age, in this case 13, and multiply it by 4. Then minus 11 from that number. Then take that end number and add it to the beginning number(maggies age) and you should get 54.
Math Equation Explanation:
13*4 = 52 (Maggies Age) x 4
52-11= 41 The question stated that Maggie's brother was 11 -------------------------------------years younger than her age times 4.
41 + 13 =54 The sum of both their ages.
