suppose your average, after taking 4 quizzes is 70 out of 100. what must your average be on the next 4 quizzes to increase your
exis [7]

Answer:

94

Step-by-step explanation:

Average = Total / Number of Data

70 \times 4 = 280

You have a total of 280 points after 4 quizzes.

4+4=8 quizzes in total

Total you need for average to be 82

82 \times 8 = 656

Number of points you need to hit required:

656 - 280 = 376

You need 376 points in total for the next 4 quizzes.

376  \div 4 = 94

You need an average of 94 points on the next 4 quizzes.

PLEASE HELP QUICK!!! WILL GIVE BRAINLIEST
aniked [119]

Answer:

Step-by-step explanation:

You can use the Pythagorean Theorem to find the length of the third side AB (Identified as "x" in the figure attached in the problem), which says that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:

a² = b²+c²

As we can see the figure, the triangle does not have an angle of 90°, but it can be divided into two equal parts, leaving two triangles with a right angle. We already have the values of the hypotenuse and a leg in triangle "A" , so we can find the value of the other leg:

b = √(a²-c²) b = √(10²-4²) b = 9.16

With these values, we can find the hypotenuse in the triangle "B": x = √b²+c² x = √(9.16)²+(4)² x = 10

Hoochie [10]

Answer:

The constant of proportionality is 3.50.

Step-by-step explanation:

We know that when y directly varies with x, such that

y=kx

The number 'k' is called the constant of proportionality.

Given the equation

y=3.50x

as

y=kx

so

k=3.50           ∵ y=kx

Here the value of k = 3.50, which is the constant of proportionality.

Therefore, the constant of proportionality is 3.50.
