Answer:
The smaller number is 24
The larger number is 45
Step-by-step explanation:
smaller number = x
Larger: 2x - 3
Smaller + larger = 69
x + 2x - 3 = 69 Combine left
3x - 3 = 69 add 3 to both sides
3x - 3+3 = 69+ 3 Combine
3x = 72 Divide by 3
3x/3 = 72/3
x = 24
Larger number = 2*24 - 3
Larger number = 45

Find the equation of the line that passes through (-1,-3) and is perpendicular to
2y=x−3
Leave your answer in the form y=mx+c
Answer:
y = -2x - 5
Step-by-step explanation:
2y = x - 3
y = 1/2x - 3/2
gradient = 1/2
perpendicular gradient = negative reciprocal = -2
y = -2x + c
(-3) = -2(-1) + c
-3 = 2 + c
-5 = c
Answer:
y = -x/2 - 7/2
Step-by-step explanation:
Equation of the line (current) in y = mx + c
2y = x - 3y = x/2 - 3/2The slope of a perpendicular line has to be -ve to the current line.
⇒ m' = -1/2
To find the y-intercept, take the x-coordinate to be 0 and substitute in the equation :
y - y₁ = m (x - x₁)
y + 3 = -1/2 (0 + 1) [Also using the point (-1, -3) to make sure line crosses it]
y + 3 = -1/2
y = -7/2
Therefore, the new equation is :
y = -x/2 - 7/2The half-life of a radioactive kind of barium is 3 minutes. If you start with 9,152 grams of it, how much will be left after 12 minutes?

How do you simplify the fractions 4/5 + 3/4 in lowest terms
Answer:
31/20
Step-by-step explanation:
First we find the greatest common denominator, for 5 and 4, that is 20.
[tex]\frac{4}{5} *\frac{4}{4} +\frac{3}{4}*\frac{5}{5} = \frac{16}{20} +\frac{15}{20} = \frac{31}{20}[/tex]
Since 31/20 isn't able to be simplified because 31 is a prime number, this is your final answer.

here are 16 sweets in a bowl.
4 of the sweets are blackcurrant.
5 of the sweets are lemon.
7 of the sweets are orange.
unna, Ravi and Sam cach take at random one sweet from the bowl.
Jork out the probability that the 5 lemon sweets are still in the bowl.
Answer:
61/112.
Step-by-step explanation:
For 5 lemon sweets to be in the bowl the 3 taken must be from the 4 blackcurrent and/or 7 orange sweets.
First work out the probability of having a lemon in one of the 3 picks:
Prob (Taking 3 lemons) = 5/16 * 4/15* 3/14 = 60/3360 = 1/56.
Prob (Taking 2 lemons and 1 blackcurrent) = 5/16*4/15*4/14 = 1/42
There are 3 ways of doing this so Probab) = 3/42 = 1/14.
Prob (Taking 1 lemon and 2 blackcurrent) = 5/16*4/15*3/14 = 1/56.
There are 3 ways of doing this so Prob = 3/56.
Prob (Taking 2 lemons and orange) = 5/16*4/15*7/14 = 140/3360 = 1/24.
There are 3 ways of doing this so Prob) = 3/24 = 1/8.
Prob (Taking 1 lemon and 2 orange) = 5/16*7/15*6/14 = 1/16
There are 3 ways of doing this so Prob = 3/16.
Therefore the probability of have 1 or more lemons in one of the 3 picks
= 1/56 + 1/14 + 3/56 + 1/8 + 3/16
= 51/112
and the probability of NOT having a lemon in one of the 3 picks
= 1 - 51/112
= 61/112.

all possible combinations if he remembers that the first digit is 6, 8, or 9.
Help pleasee!
The number of possible combinations is an illustration of principle of counting
There are 15 possible pairs of possible combinations
How to determine the number of possible combinations?
From the question, we understand that the first digit is 6, 8 or 9.
This means that the new table would not have entries that begin with 5 or 7.
The table is then represented as:
6 8 9
5 65 85 95

Jalece and Kaylyn are making brownies and muffins for a bake sale. They make 40 more muffins than brownies. They made a total of 126 sweet items for the sale. How many of each type of baked good did they make?
I really don't know I hope you can figure it out
Answer: 43 brownies and 83 muffins.
Step-by-step explanation: There are 126 sweet items in total. Jalece and Kaylyn make 40 more muffins than brownies, which means that there are more muffins than brownies. Let's try 83 muffins and 43 brownies to see if it suits what we need. With 83 muffins and 43 brownies, there are 40 more muffins than brownies, so that's correct. 83 and 43 also add up to 126, which is the total that we need.
Therefore, there are 43 brownies and 83 muffins.

The sum of the areas of two circles is 80n square meters. Find the length of a radius of each circle if
one of them is twice as long as the other.
27
GO
What is the radius of the larger circle?
Answer:
8 meters.
Step-by-step explanation:
Let the 2 radii be x and 2x, then
π x^2 + π (2x)^2 = 80π
π x^2 + π 4x^2= 80π
x^2 + 4x^2= 80
5x^2 = 80
x^2 = 16
x = 4.
So the radius of the larger circle = 2*4 = 8 m.
how to work out 4.2 × 0.03. Show the working not the answer straight! Show how you got the answer.
Answer:
1.26
Step-by-step explanation:
To solve 4.2*0.03, you move the decimal point to the right however many times to both numbers until they are whole numbers.
Doing this, we have 420*3, which took 3 decimal point shifts, so now we do 420*3 to get 1260, and then go 3 decimal places to the left to get the actual answer.
Thus, 4.2*0.03=1.260=1.26

7. The graph represents the height of a passenger car on a ferris wheel, in feet, as a

Use the graph to help you:
a. Find H(0).
b. Does H(t)=0 have a solution? Explain how you know.
c. Describe the domain of the function.
d. Describe the range of the function.
Step-by-step explanation:
Use the graph to dtermine the answer for each part of question
a)
H(0) = 5b)
H(t) = 0 has no solution as its minimum value is 5 feetc)
The domain all positive rational numbers, since time is zero or positive.d)
The range changes between 5 and 55 feet, according to the graph.Answer:
a. 5 ft
b. No - see below
c. [0, ∞)
d. [5, 55]
Step-by-step explanation:
From inspection of the graph:
x-axis: t = time (in seconds)y-axis: H(t) = height (in feet)Part a
When H(0), t = 0 ⇒ y-intercept.
Therefore, from inspection of the graph, H(0) = 5 ft
Part b
H(t) = 0 does not have a solution as the curve never touches the y-axis (when y = 0).
Part c
Domain: set of all possible input values (x-values)
The domain is time (t) (x-axis), therefore the domain is [0, ∞)
Part d
Range: set of all possible output values (y-values)
From inspection of the graph, the lowest value of H(t) is 5 and the highest value of H(t) is 55. Therefore, the range is [5, 55]
