Which of the following statements explains how you should round 213.709?
A.
Since the digit in the hundreds place is less than 5, keep the digit in the hundredths place. Then drop the digits on the right.
B.
Since the digit in the hundredths place is less than 5, keep the digit in the tenths place. Then drop the digit in the hundredths and thousandths places.
C.
Since the digit in the thousandths place is greater than or equal to 5, increase the digit in the hundredths place by 1. Then drop the digit in the thousandths place.
D.
Since the digit in the hundredths place is less than 5, leave the digit in the hundredths place and drop all the numbers on the right.
Option C is correct. Since the digit in the thousands place is 5 or greater than 5.
Given that in option C:
Since the digit in the thousandth place is greater than or equal to 5, increase the digit in the hundredth place by 1. Then drop the digit in the thousandth place.
Also, 213.709 is given in the question in which we have to round off these digits.
The digit which is just after the decimal is called tenths and just after that is hundredths and just after that is called thousandths.
Seeing the value in option C is correct as it tells the value of thousandths is greater than or equal to 5 is correct as 9 is in thousandths place and is greater than 5.
Increasing the value in the hundredth which is zero to one and dropping the digit in the thousandth place is correct as it makes the value 213.71.
All the other options don't satisfy the round of the value 213.709.
Hence, 213.71 can be rounded as per the statement written in option C.

18.9x{2x2.7}-4.6} - to the second power
The equivalent value to the expression 18.9 x [(2 x 2.7) - 4.6] - 2² is given by the following option:
C. 11.12.
How to obtain the equivalent value to the expression?The equivalent value to an expression is given by the solution to the expression.
The expression in this problem is given as follows:
18.9 x [(2 x 2.7) - 4.6] - 2²
The brackets take precedence, hence the first operation to be solved is of:
(2 x 2.7) - 4.6
The parenthesis take precedence relative to the subtraction, hence:
(2 x 2.7) - 4.6 = 5.4 - 4.6 = 0.8.
Then the expression is given by:
18.9 x [(2 x 2.7) - 4.6] - 2² = 18.9 x 0.8 - 2².
The square takes precedence, hence:
18.9 x 0.8 - 4.
Then the multiplication takes precedence, which means that the equivalent result is of:
18.9 x 0.8 - 4 = 15.12 - 4 = 11.12.

Primo car rental agency charges $25 per day plus $0.30 per mile. Ultimo car rental agency charges $30 per day plus $0.95 per mile. Find the daily mileage for which the Ultimo charge is three times the Primo charge.
The mileage is
Answer:
[tex]28\frac{4}{7}[/tex] miles
Step-by-step explanation:
mileage = m
Primo: cost = 0.3m + 20
Ultimo: cost = 0.95m + 30
Ultimo = twice Primo
0.95m + 30 = 0.6m + 40
subtract 0.60m and 30 from each side and simplify to get
0.35m = 10
divide by 0.35 into both sides to get
m = [tex]28\frac{4}{7}[/tex]
therefore, the daily mileage would be [tex]28\frac{4}{7}[/tex] miles

In this question, an airplane 30,000 feet above the ground.
It begins descending at a rate of 2,000 feet per minute.
We need to write an equation to model the situation. Also, we need to find
the altitude of the plane after 5 minutes.
Let h be the altitude of plane after t hours.
So, we get an equation,
h = 30000 - 2000t
For t = 5 minutes,
h = 30000 - 2000(5)
h = 30000 - 10000
h = 20000 feet
Therefore, an equation to model the situation: h = 30000 - 2000t

each refill. The Gold Cup costs $25 and comes with unlimited refills all summer.
Which inequality can be solved to find x, the number of refills needed to make
the Gold Cup a better value than the Silver Cup?
Answer:
10 + 0.25x < 25Less than 60 refills makes the Gold Cup a better valueStep-by-step explanation:
Let the number of refills be x.
Then the Silver Cup will cost:
10 + 0.25xThe cost of the Gold Cup is $25.
If we need the Gold Cup a better value, then required inequality is:
10 + 0.25x < 25Solve it for x:
0.25x < 25 - 100.25x < 15x < 15/0.25x < 60Answer:
Inequality = 10 + 0.25x < 25
The value of x = x < 60
Step-by-step explanation:
Now we have to,
→ find inequality used to solve for x.
Then the inequality will be,
→ $10 + 0.25x < $25
→ 10 + 0.25x < 25
Required value of x will be,
→ 10 + 0.25x < 25
→ 0.25x < 25 - 10
→ x < 15/0.25
→ [ x < 60 ]
Hence, the value of x < 60.

The parent function for linear functions is y=mx +b.
First, find the slope using the slope formula (y2-y1)/(x2-x1)
(30-10)/(8-3) = 20/5 = 4
Now, plug in known values to solve for "b", which is the y-intercept:
10 = 4(3) + b
10 = 12 + b
10 - 12 = b

A bread company makes two types of wheat bread, light whole wheat and regular
whole wheat. A loaf of light whole wheat bread requires 2 cups of flour and 1
egg. A loaf of regular whole wheat bread requires 3 cups of flour and 2 eggs. The
bakery has 90 cups of flour and 80 eggs on hand. The profit on the light bread is
$1 per loaf and on the regular bread is $1.50 per loaf. In order to maximize
profits, how many of each loaf should the bakery make?
By the equations, he should make 70 whole wheat bread that would earn a profit of $105 that is maximum he can earn with the given amount of flour and egg.
What is system of equation?simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution. A group of two or more equations that share the same variables is known as a system of equations. A set of values for a variable that simultaneously satisfy each equation is the solution to a system of equations. When there are multiple unknowns and there is sufficient data to set up equations in those unknowns, systems of equations are used to solve applications. In general, we need sufficient information to construct equations in the n unknowns.
Here,
Let x be light whole wheat and y be the regular whole wheat.
given,
A loaf of light whole wheat bread requires 2 cups of flour and 1 egg.
A loaf of regular whole wheat bread requires 3 cups of flour and 2 eggs.
The bakery has 90 cups of flour and 80 eggs on hand.
So the system of equation will be,
2x+3y=90
x+2y=80
multiply the second equation by 2,
2x+4y=160
2x+3y=90
subtract the equations,
y=70
by this,
x=-60
So by this he should make 70 whole wheat bread that will make him earn a profit of,
=70*1.5
=$105
According to the calculations, he should produce 70 loaves of whole wheat bread for a profit of $105; this is the most he can make with the supplied quantities of flour and egg.

The result of the given expression is 2.5.
We are given a mathematical expression. Let the expression be denoted by the variable "E". The expression is given below.
E = (45 / 6) % 5
We need to simplify the expression and find its value. First of all, we will solve the brackets.
E = (7.5) % 5
Now we will solve the modulus operator. The modulus operator "%" gives us the remainder after the division of the two numbers. After dividing one number by another, the modulo operation yields the remainder, or signed remainder, of the division.

The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle.
Now using the Pythagoras theorem we can find out the length of the other wall
b²+p²=h²
So here h=13ft and b=5ft
p²= h²-b²
= 13²-5²
