Of the students at I.S. 59, 230 signed up for the school picnic. That was 50% of all students in the school. How many students attend I.S. 59
Answer: 460 students
Step-by-step explanation:
Based on the information given in the question, let the total number of students that attend I.S. 59 be represented by x.
Since we've been given the information that 230 signed up for the school picnic which was 50% of all students in the school. Then, the students in the school will be:
= 50% of x = 230
0.5 × x = 230
0.5x = 230
x = 230/0.5
x = 460
Therefore, 460 students attend the school.

Find the distance between each pair of points. You may want to plot the points. (2 pts each) (2, 3), (7, 3) (-2, 5), (-2, -3) (-8, 5), (-2, 5) (-9, 1), (6, 1)
Answer:
(1) First pair; (2, 3), (7, 3), d₁ = 5
(2) Second pair; (-2, 5), (-2, -3), d₂ = 8
(3) Third pair; (-8, 5), (-2, 5), d₃ = 6
(4) Fourth pair; (-9, 1), (6, 1), d₄ = 15
Step-by-step explanation:
Given pair of points;
(1) (2, 3), (7, 3)
(2) (-2, 5), (-2, -3)
(3) (-8, 5), (-2, 5)
(4) ) (-9, 1), (6, 1)

[tex]d = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2}[/tex]
(1) first pair; (2, 3), (7, 3)
[tex]d_1 = \sqrt{(3-3)^2 + (7-2)^2} \\\\d_1 = 5[/tex]
(2) second pair; (-2, 5), (-2, -3)
[tex]d_2 = \sqrt{(-3-5)^2 + (-2-(-2))^2}\\\\d_2 = \sqrt{(-3-5)^2 + (-2+2)^2} \\\\d_2 = 8[/tex]
(3) Third pair; (-8, 5), (-2, 5)
[tex]d_3 = \sqrt{(5-5)^2 + (-2-(-8))^2}\\\\d_3 = \sqrt{(5-5)^2 + (-2+8)^2} \\\\d_3 = 6[/tex]
(4) Fourth pair; (-9, 1), (6, 1)
[tex]d_4 = \sqrt{(1-1)^2 + (6-(-9))^2}\\\\d_4 = \sqrt{(1-1)^2 + (6+9)^2} \\\\d_4 = 15[/tex]

subtract 21 from both sides
-15 = -5x
divide each side by -5

For any positive numbers a,b, and d, with b not equal to 1, log base b (a/d) = A. Log base b a * log base b d B. Log base b a + log base b d C. Log base b a - log base b d D. D * log base b a
Answer:
C. Log base b (a) - Log base b (d)
Step-by-step explanation:
In logarithm, log means index or exponent. It can be explained with following example. Consider 2^5 = 32
here index = log = 5 so you can write the log of 32 = 5
Consider 64/16 = 4
now 64 = 2^6 and 16 = 2^4
We can write log 2(64) = 6 and log2(16)=4
Now log 64/16= log 4= 2
Also log2(64)-log2(16)=6-4=2
Therefore
Log base b (a/d) = Log base b (a) - Log base b (d)

Answer:
First option, [tex]\frac{-2y+5x}{3x-2y}[/tex]
Step-by-step explanation:
Simplify the fraction. To make the process of solving easier, we can multiply both the numerator and denominator by x and y to get rid of the fractions as seen below. This is because the variables in the denominators of the fractions will cancel out with either the matching x or y in the numerators.
[tex]\frac{\frac{-2}{x} +\frac{5}{y} }{\frac{3}{y}-\frac{2}{x} } \\=\frac{(\frac{-2}{x} +\frac{5}{y})xy }{(\frac{3}{y}-\frac{2}{x})xy }\\=\frac{-2y+5x}{3x-2y}[/tex]
Thus, the first option is correct.

An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms. 3/4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh? (no decimals)
Answer:Weight of wood part of the sculpture (no decimals) =4kg
Step-by-step explanation:
Weight of sculpture containing metal and wood = 14.9 kg
weight of metal =3/4 x 14.9 kg =11.175kg
weight of wood =Entire sculpture − weight of metal
= 14.9 kg−11.175kg
=3.725kg
Rounding up to remove decimals we have that Weight of wood part =4kg

The length of AC is 6.4 unit.
The correct option is C.
We have the figure from which we can say that
BD is the diameter which is
= 4.8 + 1.6
= 6.4 unit long.
Now, AC is the chord.
As, the distance between the two opposite point the the surface of circle would be same.
Then, the length of AC = length of BD
Thus, the length of AC is 6.4 unit.
