Djamil stands under a waterfall that is 75 feet tall. The distance of the of waterfall with respect to its time is:
h(t) = -16t^2 + 75
How long will it take water from the top to reach the bottom?​

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

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)

Step-by-step explanation:

5(p/100)=3 multiply each side by 100

5p=300 divide each side by 5

p=60%

Answer:

Step-by-step explanation:

area = ½×base×height

21 = ½(x+1)x

42 = (x+1)x

x² + x - 42 = 0

(x+7)(x-6) = 0

x = -7, 6

-7 is an extraneous solution, so x = 6

A triangle is a three-edged polygon with three vertices. The value of x is 6.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angle of a triangle is always equal to 180°.

The area of the triangle is half the product of the base of the triangle and the height of the triangle.

Given that base of the triangle is x+1, while the height of the triangle is x. Also, the area of the triangle is 21 units².

Area of triangle = (1/2) ×  height of the triangle × length of the base

21 = (1/2) × x × (x+1)

21 = (1/2)(x² + x)

21 × 2 = x² + x

42 = x² + x

x² + x - 42 = 0

x² + 7x - 6x - 42 = 0

x(x + 7) - 6(x + 7) = 0

(x + 7)(x - 6) = 0

x = -7, 6

Now, since the value of x can not be negative. Therefore, the value of x is 6.

Hence, the value of x is 6.

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.

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.
