Answer: 79%
Step-by-step explanation:
Javon's first 3 quizzes had a mean score of 90%. This means that his total score will be:
= 90% × 3
= 270%
Since he scores 46% on his next quiz, we add it to the previous score and this will be:
= 270 + 46
= 316
Then, his mean quiz score for these 4 quizzes will be:
= Total score / Number of quizzes
= 316 / 4
= 79%
Answer:
79%
Step-by-step explanation:
316 / 4 = 79%

Which of the following is a property of all squares?
A.
There is only 1 pair of parallel sides.
B.
All 4 sides are congruent.
C.
There are 4 acute angles.
D.
Consecutive angles are complementary.
Answer:D.All sides are congruent
The solution is: a) Opposite sides are parallel, the following is true for all parallelograms.
What is parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
Here, we have
a) In a parallelogram, opposite sides are parallel (which is why it is called a Parallelogram).
b) Opposite angles are congruent (not ALL angles). The only parallelograms where all of the angles are congruent are Squares and Rectangles.
c) Consecutive angles are supplementary so their SUM must be 180°. Therefore if one angle is less than 90° (acute), the other angle must be greater than 90° so it is not possible that all angles are acute (∠ 90°).
d) The sides do not have to be equal. The only parallelogram whose sides have equal lengths are Squares.
Hence, The solution is: a) Opposite sides are parallel, the following is true for all parallelograms.

Answer:
666.67π .ft^3
here's your solution
=> radius of cone = 10 ft
=> height of cone = 20 ft
=> volume of cone = πr^2h/3
=> putting the value of radius and height
=> volume = 10^2*20/3π
=> volume = 666.67π .ft^3

A tabletop in the shape of a trapezoid has an area of 5029 square cenimeters. Its longer base measures 123 cenimeters, and the shorter base is 65 cenimeters. What is the height?
Answer:
Length of height = 53.5 cm
Step-by-step explanation:
Given:
Area of trapezoid = 5,029 cm²
Length of longer base = 123 cm
Length of shorter base = 65 cm
Find:
Length of height
Computation:
Area of trapezoid = [(a+b)/2]h
5,029 = [(123 + 65)/2]h
5,029 = [(188)/2]h
5,029 = [94]h
Length of height = 53.5 cm

Since this is a right triangle, we can use the Pythagorean theorem
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + (2.1)^2 = (2.9)^2
a^2 +4.41=8.41
a^2 = 8.41-4.41
a^2 =4
Take the square root of each side
sqrt(a^2)=sqrt(4)
a=2

find the value of angel 0 to the nearest 10th
Answer: 36.9
Step-by-step explanation:
For this question you have to find out whether you are using Sin, Cos or Tan.
To work out which one you are using you can use SOH CAH TOA to help you.
SOH- The 'S' is for Sin, the 'O' and the 'H' is for Opposite over Hypotenuse.
CAH- The 'C' is for Cos and the 'A' and the 'H' is for Adjacent over Hypotenuse.
TOA- The 'T' is for Tan, the 'O' and the 'A is for Opposite over Adjacent.
As you have the Opposite (the side opposite the angle we're looking for) and the Adjacent (the side next to the angle were looking for) we would be using Tan.
So first you would have to write:
Tanθ=3/4
Then because we want Theta (θ) on it's own we would have to do the inverse to 'undo' the equation. Tan-1 is the inverse of Tan.
θ=Tan-1 3/4
To find the answer you would have to put it in your calculator.
θ=36.9

a recipe calls for 5/8 cup of sugar for every 5 teaspoons of vanilla. what is the unit rate in cups per teaspoon?
a) 3 1/8
b) 1/8
c) 8
d) 8/25
Answer:
b) 1/8
Step-by-step explanation:
5/8 ÷ 5 = 1/8
The unit rate in cups per teaspoon is 1/8 cup of sugar.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
5/8 cup of sugar=5 teaspoons of vanilla.
or, 5 teaspoons of vanilla = 5/8 cup of sugar
So, 1 teaspoon of vanilla = (5/8)/5 cup of sugar
(5/8)/5 = (5/8)*(1/5)
(5/8)/5 =1/8
So, 1 teaspoon of vanilla = 1/8 cup of sugar
Hence, the unit rate in cups per teaspoon is 1/8 cup of sugar.
