Is the side length √ 23+3 rational or irrational? Explain your reasoning.
100 points but If you answer something random I will report.
Answer:
Irrational
Step-by-step explanation:
[tex] \sqrt{23 + 3 } = \sqrt{26} [/tex]
An irrational number is a number that cannot be written as a fraction. Therefore √26 is an irrational number.
Irrational
Step-by-step explanation:
An irrational number is a number that cannot be written as a fraction. Which means that √23 is an irrational number.
What are the two words that allow you to check your division problem backward?
Answer:
inverse operation
Step-by-step explanation:
Inverse means opposite. The opposite of division is multiplication. For example, if you divided 15 by 3, the answer is 5. If you multiply 5 by 3, the answer is 15. You know your answer is correct by checking it with the inverse operation.

Prove that the conjecture is false by providing a counter example.
Answer:
Any negative number would be a counterexample.
Step-by-step explanation:
Since negative numbers get smaller as you multiply them by a larger number, this would prove this conjecture false.

A secretary earns $12 an hour and worked a total of 47 hours last week she earns time and a half for work beyond 40hours calculate her pay
Answer:
$606
Step-by-step explanation:
For the first 40 hours, she was making $12. With this, we can do 12x40, which is 480$. We can store that in a safe space for later access. Afterwards, since the problem says that "after 40 hours she earns time and a half for her work" we can assume she gets 1.5x her pay after 40 hours, which is $18 (We can get this by 12 / 2 = 6. Then do 12 + 6 = 18). Then we can do 18x7 because she worked 7 hours over 40. With that, we get 126$. Now we can do 480$ + 126$ = 606$. So, she earned 606$.
What’s the y-intercept of the line graphed on the grid?
Answer:
y-intercept is 4.5
Step-by-step explanation:That is when the line intersects the y-axis
Answer:
y intercept = 5.5
Step-by-step explanation:
The y-axis is the vertical (up and down) line in the center of the graph. When the line passes over it, wherever it passes, will be your y intercept.
In this situation it passes in the middle of 5 and 6 so it would be 5.5.

When a coordinate grid is superimposed on a map of lanesville the middle school is located at (15,13) and the librart is located at (27,9). If each unit represents 1 mile how many miles apart are the middle school in the liebrary round your answer to the nearest 10th
Answer:
4.5 miles
Step-by-step explanation:
Given
[tex]Middle\ School = (15,13)[/tex]
[tex]Library = (27,9)[/tex]
To solve this, we simply solve for the distance (D) between both points.
[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Where:
[tex](x_1,y_1) = (15,13)[/tex]
[tex](x_2,y_2) = (27,9)[/tex]
[tex]D = \sqrt{(27 - 25)^2 + (9 - 13)^2}[/tex]
[tex]D = \sqrt{(2)^2 + (-4)^2}[/tex]
[tex]D = \sqrt{4 + 16}[/tex]
[tex]D = \sqrt{20}[/tex]
[tex]D=4.472135955[/tex]
[tex]D=4.5[/tex] --- approximated
Since each unit is 1 mile. The distance is 4.5 miles

Compare 2 4/5 ? 2.325
Answer:
>
Step-by-step explanation:
2.8>2.325
answer: > p l e a s e m a r k b r a i n l e s t .
this is because 2 4/5 = 2.800 and 2.800 is bigger than 2.325 because in the tenths place column (the column closest to the decimal without going over it), 8 is bigger than 3 so 2.800 is bigger than 2.325. So the answer is 2 4/5 > 2.325.

(7.15×105)–(5.964×105)
Answer:
124.53
Step-by-step explanation:
7.15×105=750.75
5.964×105=626.22
750.75-626.22= 124.53
lmk if this is right or not :)
Answer with step-by-step explanation:
(7.15 × 105) - (5.964 × 105) = 124.53

Which of the following regular polygons circumscribed about a circle provides the best estimate for the area of that circle?
dodecagon
decagon
20-gon
11-gon
Answer:
The correct option is;
20-gon
Step-by-step explanation:
The area, A, of a regular polygon is given as follows;
[tex]A = \dfrac{n \times s \times a}{2} = \dfrac{P_p \times a}{2}[/tex]
Where;
n = The number of sides
s = The length of one side of the polygon
a = The apothem
[tex]P_p[/tex] = The perimeter of the polygon
Where
The area of a circle, A[tex]_c[/tex] = π×r² = π × r × r = 2× π × r × r/2 = P/2 × r
Given that the apothem, a, of a 20-gon circumscribed about a circle is approximately the length of the radius of the circle, and the perimeter of the 20-gon is approximately the perimeter (circumference) of the circle, the area of the 20-gon circumscribed about a circle provides the best estimate for the area of the circle.
A cookie recipe calls for ¾ cups of sugar. The recipe makes 20 cookies. How much sugar is required to make 80 cookies
Answer:
So based on the given problem above, it says that, for one batch with 3/4 cup of brown sugar can make 6 dozen big cookies. If we are to make 15 dozen cookies, what we need to do is to divide 3/4 cup of brown sugar by 6 dozen, and we get 0.125. This means that per dozen, it is equivalent to 0.125 cup of brown sugar. If we multiply it by 15 dozens, we get 1.875 cup or 1 and 7/8 cup of brown sugar.
Answer:
3 cups of sugar.
Step-by-step explanation:
80/20 = 4 batches
3/4 cups x 4 = 3 cups of sugar
