In January, Mr Tan's students read 20 books. In Febuary, they read 15 books. What is the percent increase or decrease in the number of books they read?
A. 5% decrease
B. 15% increase
C. 25% increase
D. 25% decrease
Answer:
D. 25% decrease
Step-by-step explanation:
Since it's clear that they read less books to find how much it decreased we multiply 100 with 15 then divide it by 20
100 × 15 ÷ 20 = 75 this result shows a 25% decrease.

if diameter of a circle is 28cm.find radius & circumference.
Answer:
Radius = 14 cm, Circumference = 88 cm
Step-by-step explanation:
d = 28 cm
r = 1 / 2 * 28
= 14 cm
Circumference = 2πr
= 2 * 22 / 7 * 14
= 2 * 22 * 2
= 88 cm
Hope it helps :)
Please mark my answer as the brainliest
Step-by-step explanation:
Diameter (d) = 28 cmRadius (R) = d /2 = 28 / 2 = 14 cmCircumference (C) = πd= 3.14 * 28= 87.92[tex]hope \: it \: will \: help[/tex]

Answer:
m∠PNO = 60°
m∠O = 33°
Step-by-step explanation:
∡NPO is 87° because it's a vertical angle with the 87° angle
3) ∡PNO is supplementary to the 120° angle (they must add to 180°)
4) m∠O = 180 - (60 + 87) = 33

Cos = 5/36
Answer:
Step-by-step explanation:
"cos" by itself is meaningless. It needs an argument.
cos(x°) = 5/36
x° = arccos(5/36) ≅ 82.2°
The smith family went out for dinner the price of the meal was $39.85 the sales tax was 8.1% of the price of the meal the tip was 17% of the meal and the sales tax how much did the smith family pay for the meal including tax and tip PLEASE HELP ILL GIVE LOTS OF POINTS
9514 1404 393
Answer:
$50.40
Step-by-step explanation:
Adding the tax multiplies the amount by 1+8.1% = 1.081.
Adding the tip multiplies the amount by 1+17% = 1.17.
Then the amount with tax and tip is ...
$39.85 × 1.081 × 1.17 = $50.40
The Smith family paid $50.40 for the meal.
is 25 meters longer then 35 yards
Which of the following equations could you solve by first adding six and then dividing by negative three?
6 - 3 x = -9
+ 6 = -9
-3 x - 6 = -9
3 x - 6 = -9
Answer:
-3x - 6 = -9 (The third answer)
Step-by-step explanation:
When solving for x, you have to undo each operation. When solving -3x - 6 = -9, you have to undo the -6 first. To do this, add 6 to both sides. Then, you must undo the -3x. To do this, divide by -3 from both sides.

B (27, 30)
Point A has coordinates (3, 2)
Point B has coordinates (27, 30)
Point C is marked on the diagram.
Work out the coordinates of C.
Answer:
The coordinates of C are (15,16)
Step-by-step explanation:
As we can see, point C lies half the distance of AB
So we can use the midpoint formula to get the coordinates of C
we have this as:
(x,y) = (x1 + x2)/2 , (y1 + y2)/2
(x1,y1) = (3,2)
(x2,y2) = (27,30)
Thus, we have
(x,y) = (3 + 27)/2, (30 + 2)/2
(x,y) = 30/2 , 32/2
(x,y) = (15,16)

Find the slope-intercept form of an equation of the line perpendicular to the graph of x – 3y = 5 and passing through (0, 6).
Answer:
y=-3x+6
Step-by-step explanation:
x-3y=5
y=1/3x-5/3
slope of perpendicular line is -3 (opposite reciprocals)
y=mx+b
x=0 and y=6
6=3x+b
6=3(0)+b
6=b
y=-3x+6

Answer:
Here
Step-by-step explanation:
If m<1=(6x+25), and m<2=(x+5), find m<2
Answer:
Assuming they are equal to each other, X = -4
Step-by-step explanation:
6x + 25 = x + 5
Subtract 5 from both sides
6x + 20 = x
subtract 6x from the left side
20= 5x
divide by 5
-4 = x

[tex]\frac{3}{x+3} -\frac{4}{x-3}=\frac{5x}{x^{2} -9}[/tex]
Answer:
Step-by-step explanation:
[tex]\frac{3}{x+3}-\frac{4}{x-3}=\frac{3*(x-3)}{(x+3)(x-3)}-\frac{4(x+3)}{(x-3)(x+3)}\\\\=\frac{3*x-3*3}{(x+3)(x-3)}-\frac{4*x+4*3}{(x+3)(x-3)}\\\\=\frac{3x-9}{x^{2}-3^{2}}-\frac{4x+12}{x^{2}-3^{2}}\\\\=\frac{3x - 9 -(4x + 12)}{x^{2}-3^{2}}\\\\=\frac{3x-9-4x-12}{x^{2}-9}\\\\=\frac{-x-21}{x^{2}-9}\\\\[/tex]
[tex]\frac{3}{x+3}-\frac{4}{x-3}=\frac{5x}{x^{2}-9}\\\\\frac{-x-21}{x^{2}-9}=\frac{5x}{x^{2}-9}\\\\-x-21=\frac{5x}{(x^{2}-9)}*(x^{2}-9)\\[/tex]
-x - 21 = 5x
Add 'x' to both sides
-x -21 +x = 5x + x
-21 = 6x
6x = -21
x = -21/6
= -7/2
x = -3.5
9 A rectangle of perimeter 42 cm is
pcm long and q cm broad. If the
difference between the length and
breadth is 9 cm. find
pand q
the area of the rectangle
Answer:
The correct answer is = p = 15 and q = 6.
Step-by-step explanation:
Given:
Perimeter of rectangle = 42 cm
p - q = 9 cm
length = p
width = q
we know:
Perimeter of rectangle= 2(l+w)
solution:
42 = 2(P+q)
21= p+q
Difference of p and q = 9 cm.
Then, P+q=21 .... 1
P-q=9 ....2
Adding both 1 and 2
2P = 30
P= 15cm and
q = 15-9
= 6cm
