Answer: A:B = 3:13
Step-by-step explanation:
B 5, A 3 (double to get rid of halves)
B 10, A 6, —> B 13 A 3
The question needs you to find the new ratio of the glasses
The new ratio of glass A to glass B = 2.5 : 5.5
Glass A = 5
Glass B = 3
Half of the orange juice in Glass A is poured into Glass B
B = 3 + 1/2 of 5
= 3 + (1/2×5)
= 3 + 5/2
= 6 + 5 / 2
= 11/2
B = 11/2
= 5.5
A = 5 - 1/2 of 5
= 5 - (1/2×5)
= 5 - 5/2
= 10-5/2
= 5/2
= 2.5
The new ratio of glass A to glass B = 2.5 : 5.5

Find the value of x.
х
50°
The unknown value of x from the diagram is 80 degrees.
The given diagram is an isosceles triangle.
The base angle of an isosceles triangle are equal
The sum of angle in a triangle is also 180 degrees. Hence:
x + 50 + 50 = 180
x + 100 = 180
Subtract 100 from both sides
x + 100 - 100 = 180 - 100
x = 80 degrees
Hence the unknown value of x from the diagram is 80 degrees.

Rewrite the polynomial as a product of the monomial and the polynomial. −15a^2bc+20ab^2c−25bc^3
Answer:
Step-by-step explanation:
15a²bc = 3·5·a²·b·c
20ab²c = 2²·5·a·b²·c
25bc³ = 5²·b·c³
greatest common factor: 5bc
(-15a²bc + 20ab²c - 25bc³)÷(5bc) = -3a² + 4ab - 5c²
-15a²bc + 20ab²c - 25bc³ = (-3a² + 4ab - 5c²)(5bc)

x= −1/4 or x = 5
Step-by-step explanation:
Step 1: Factor left side of equation.
(4x+1)(x−5)=0
Step 2: Set factors equal to 0.
4x+1=0 or x−5=0
Answer:
x= −1/4 or x = 5
The factored form of the equation 4x²- 19x - 5 = 0 is (4x+1)(x-5).
The given equation is 4x²- 19x - 5 = 0.
To factor the quadratic expression on the left-hand side into two binomials.
The binomial factors will have the form (ax + b)(cx + d).
We need to find two numbers whose product is equal to ac (the coefficient of x² term) multiplied by d (the constant term), which is (4)(-5) = -20, and whose sum is equal to the coefficient of the x term, -19.
After considering different factor pairs of -20, we find that -20 and +1 satisfy the requirements.
(4x² - 20x) + (x - 5) = 0.
4x(x - 5) + (x - 5) = 0.
(4x+1)(x-5)=0

Step-by-step explanation:

[7TH GRADE MATH] Can someone please explain how to round a square root to the tenth place without using a calculator.
(I WILL BE GIVING BRAINLIEST!!!!)
Answer:
Step-by-step explanation: To find a decimal approximation to, say √2, first make an initial guess, then square the guess, and depending how close you got, improve your guess. Since this method involves squaring the guess (multiplying the number times itself), it uses the actual definition of square root, and so can be very helpful in teaching the concept of square root.
Example: what is square root of 20?
You can start out by noting that since √16 = 4 and √25 = 5, then √20 must be between 4 and 5.
Then make a guess for √20; let's say for example that it is 4.5. Square that, see if the result is over or under 20, and improve your guess based on that. Repeat this process until you have the desired accuracy (amount of decimals). It's that simple and can be a nice experiment for students!
Answer:
The number’s square root is a number that, when multiplied by itself, equals the first number. Another way of saying this is: “What can we multiply by itself to get the number in question?”
Step-by-step explanation:
For example, the square root of 1 is 1 because 1 multiplied by 1 equals 1 (1X1=1). However, the square root of 4 is 2 because 2 multiplied by 2 equals 4 (2X2=4). Think of the square root concept by imagining a tree. A tree grows from an acorn. Thus, it’s bigger than but related to the acorn, which was at its root. In the above example, 4 is the tree, and 2 is the acorn.
Thus, the square root of 9 is 3 (3X3=9), of 16 is 4 (4X4=16), of 25 is 5 (5X5=25), of 36 is 6 (6X6=36), of 49 is 7 (7X7=49), or 64 is 8 (8X8=64), of 81 is 9 (9X9=81), and of 100 is 10 (10X10=100).[1]

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of students in the freshman class be = A
Now , the equation will be
The total number of students in the university = 5600 students
The percentage of students in the freshman class = 48 %
So ,
The total number of students in the freshman class = percentage of students in the freshman class x total number of students in the university
Substituting the values in the equation , we get
The total number of students in the freshman class = ( 48/100 ) x 5600
The total number of students in the freshman class = 0.48 x 5600
The total number of students in the freshman class = 2688 students
Therefore , the value of A is 2688 students
Hence ,
The total number of students in the freshman class is 2688 students
