If the area of a square is 33 square inches, which is greater: the length of a side of the of a side of the square to the nearest tenth of an inch or the square root of 40?
Answers
Answer:
square root of 40 is greater than side of the square
Step-by-step explanation:
First we find square root of 40
[tex]\sqrt{40} = 6.325[/tex]
Now
given
area of a square is 33 square inches
we know area of square is side square
area of square = [tex]side^2[/tex]
[tex]side^2 = 33\\\sqrt{side^2} = \sqrt{33}\\side = 5.745[/tex]
Thus, we see length side of square is 5.7 inches
and square root of 40 is 6.325
since
6.325 > 5.7
hence square root of 40 is greater

A)
x+y≤14; 10x+15y≥125.
B)
x+y≤14; 15x+10y≥125.
C)
x+y≥14; 15x+10y≥125.
D)
x+y≤125; 15x+10y≥14.
Answers
Answer:
Step-by-step explanation:
C
The system of inequalities representing the given situation is x + y ≥ 14; 15x + 10y ≥ 125. which is the correct answer would be an option (C)
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
To determine the number of hours should he spend on each job if he wants to earn at least $125 each week.
Let the hours of tutoring would be x
And y the hours of babysitting would be y
Given that He can work no more than 14 hours a week.
So inequality as per the above situation is: x + y ≥ 14
Since he charges $15 an hour for tutoring and $10 an hour for babysitting.
If he wants to earn at least $125 each week.
So inequality as per the above situation is: 15x + 10y ≥ 125
Therefore, the correct answer would be option (C).

If x is the number of 30-day periods, then the equation _____
nothing can be used to find the number of 30-day periods until the values of the gift cards will be equal
Answers
Answer:
a) Equation: 115 - 2.5x = 95 - 2x
ii) x = 40
b) The value of each gift card for which they'll be equal = 15
Step-by-step explanation:
a) Equation for the number of 30 days until the value of the gift cards are equal:
card 1: gift card for 115 that loses 2.50 for each 30-day period
115 - 2.5x - - - - (1)
card 2: gift card for 95 that loses 2 for each 30-day period
95 - 2x - - - - - - (2)
equation for the number of 30 day period (x) for which the amount on card 1 is eqaul to the amount on card 2 is given by:
115 - 2.5x = 95 - 2x
making x the subject of the formula:
115 - 95 = -2x + 2.5x
20 = 0.5x - - - - (i)
x = 20 ÷ 0.5
x = 40
b) the value on the gift card
From expression 1 above; 115 - 2.5x
where x = 40
115 - 2.5x = 115 - 2.5(40)
= 115 - 100 = 15
from expression (2); 95 - 2x
95 - 2(40) = 95 - 80 = 15
∴ The value of each gift card for which they'll be equal = 15

Which statement is true about parallel lines?
A. They intersect and are coplanar.
B. They intersect, but are not coplanar.
C. They do not intersect, but are coplanar.
D. They do not intersect and are not coplanar.
Answers
Answer:
C( They do not intersect, but are coplanar
Step-by-step explanation:
Parallel lines are coplanar (they lie in the same plane) and never intersect.
The statement that is true about parallel lines is that they do not intersect, but are coplanar: Option C is correct.
Lines are 2-dimensional figures that are used to connect two on more points in a xy-plane.
For two lines to be parallel, this means that the lines;
cannot meet each other i.e. they can not intersectThey can lie on the same plane i.e they can be coplanarHence we can conclude that the statement that is true about parallel lines is that they do not intersect, but are coplanar.

Mia and her children went into a grocery store and where they sell apples for $2 each and mangos for $1.50 each. Mia has $20 to spend and must buy no less than 9 apples and mangos altogether. If Mia decided to buy 3 mangos, determine the maximum number of apples that she could buy.
Answers
The maximum number of apples that she can buy is 7.75.
We are given that:
- Apples cost $2 each.
- Mangos cost $1.50 each.
- Mia has $20 to spend.
- Mia must buy no less than 9 apples and mangos altogether.
- Mia decided to buy 3 mangos.
Now,
we can write the following system of equations:
[tex]$\begin{cases}2a + 1.5m \leq 20\\a + m \geq 9\\m = 3\end{cases}$[/tex]
Substituting $m = 3$ into the second equation, we get:
[tex]$a + 3 \geq 9 \Rightarrow a \geq 6$[/tex]
So, Mia must buy at least 6 apples.
To determine the maximum number of apples that she could buy, we can substitute m = 3 into the first equation and solve for a:
[tex]$2a + 1.5(3) \leq 20 \Rightarrow a \leq \frac{20 - 4.5}{2} = 7.75$[/tex]
Therefore, by equation answer will be 7.75.
