the sum of two numbers is 103. If the greater number is divided by the smaller number the quotient is 2 and the remainder is 10 find the number
Answers
9514 1404 393
Answer:
31 and 72
Step-by-step explanation:
Let x be the smaller number and y be the larger number. Then we have ...
x + y = 103 . . . . . sum is 103
y = 2x +10 . . . . . y/x is 2 remainder 10
Substituting for y, we get ...
x + (2x +10) = 103
3x = 93
x = 31
y = 103 -31 = 72
The two numbers are 31 and 72.

12 is 30% of______________ pls help
Answers
Answer:
40
the
answer
is
40
Answer:
The 30% of a number can be calculated multiplying that number by 0.3, so, if we call the number we don't know x, we can write this equation:
0.3x = 12
And then solve it for x::
x = 12/0.3 = 40
So now we know that the number is 40.
We can replace the 40 in the equation to get if our answer is correct or not..
30% of 40: 0.3 * 40 = 12
And then, we see it's correct

If tan 2A = cot (A -18°), where 2A is an acute angle, find the value of A.
Answers
answer will be -24
A=-24
Answer:
A = 36
Step-by-step explanation:
Using the cofunction identity
tan(90 - x) = cotx
Given
tan2A = cot(A - 18) , then
90 - 2A = A - 18 ( add 2A to both sides )
90 = 3A - 18 ( add 18 to both sides )
108 = 3A ( divide both sides by 3 )
36 = A

Bob's linear speed is higher than Jack's because the radius of the circle
around which Bob rotates is larger.
Responses:
Jack's linear speed is approximately 377 feet per minuteBob's linear speed is approximately 527.8 feet per minuteWhat is the relationship between linear speed and angular speed?Given:
The rotational speed of the merry go round = 6 revolution per minute
Jack's distance from the center = 10 feet
Bob's distance from the center = 14 feet
The angular speed, ω, of the merry-go-round is found as follows;
[tex]\omega = \mathbf{\dfrac{6 \times 2 \cdot \pi}{1 \ minute}} = 12 \cdot \pi \ rad/minute[/tex]Linear speed = ω × rWhich gives;

Answer:
y = -1x + 2
Step-by-step explanation:
We need to find y = mx + b
Use the following equation
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Plug in the values
[tex]\frac{-1-0}{3-2}[/tex] = [tex]\frac{-1}{1} = -1[/tex]
We have found the slope(m) which is -1
We have to find y-int b
Plug in any given x,y into the slope formula
-1 = -1(3) + b
-1 = -3 + b
2 = b
At last the formula is
y = -1x + 2

Find the inequality represented by the graph.
Answers
Answer:
y > 1/3 x - 3
Step-by-step explanation:
First, it would be easiest to find the equation of the line from the two integer points given, which are (0, -3) and (3, -2).
Find the change of y over the change of x to get the slope of the line.
(-2 - (-3))/(3 - 0) = 1/3
Since the line intercepts the y axis at (0, -3), the equation of the line would be
y = 1/3x - 3
We can see that the shaded portion is above the line, (and that the line is dotted) so this graph represents
y > 1/3 x - 3

The numerator of a fraction is 6 more than the denominator. If 5 is subtracted from the denominator, the fraction becomes 3/2. Find the fraction
Answers
Answer:
The fraction is 32/27
Step-by-step explanation:
let the fraction be x/y
x - y = 6
x = 6 + y ••••••(i)
This is according to the first sentence
Furthermore;
x/y-5 = 3/2
2x = 3(y-5) •••••(ii)
Substitute
2(6 + y) = 3y - 15
12 + 2y = 3y - 15
3y -2y = 12 + 15
y = 27
x = 6 + y
x = 6 + 27 = 33
