Answer:
3 1/3
Step-by-step explanation:
First you make the denominators the same so you would change 5/4 to 10/8
and 3 X 3 1/3 gets you 10/8
The longer leg of a right triangle is 4 more than the short leg. The hypotenuse is eight less than the sum of the 2 legs.
Solve
Please help !
Answer:
In bold below.
Step-by-step explanation:
let the shorter leg be x units long, then:
longer leg = x+4
and hypotenuse = x + x + 4 - 8 = 2x - 4 units.
By Pythagoras:
(2x - 4)^2 = x^2 + (x + 4)^2
4x^2 - 16x + 16 = x^2 + x^2 +8x + 16
2x^2 - 24x = 0
2x(x - 12) = 0
x = 12.
So the shorter leg = 12 units
Longer leg = 4 + 12 = 16 units and
Hypotenuse = 12 + 16 - 8 = 20 units.
Point D is the in center of triangle ABC. Write an expression for the length x in terms of the three side lengths AB, AC, BC.
Hint: Use areas of triangles...A=1/2bh
Answer:
[tex]x = \frac{2(A_T) }{(AB) + (AC) + (BC)} [/tex]
Problem #4 My teacher said that for every student who earned an A on the last
quiz, three students earned a B. If four students earned an A, how many earned a
B? Why? Explain.
Answer:
12
Step-by-step explanation:
We can write the following ratio
1:3 (for every student who gets an A 3 gets a b)
We then can write a new ratio
4:x
We can solve this ratio by multiplying the original ratio by 4
4:12
This means that 12 people earned an B

Find the value of x. Your answer must be
Exact
Answer:
x = 8
Step-by-step explanation:
sin (30) = 4/x => solve for x.
Answer:
[tex]x=8[/tex]
Step-by-step explanation:
Use the sine ratio because we have the hypotenuse and side opposite the given angle to work with:
[tex]sineX=\frac{opposite}{hypotenuse}[/tex]
Insert the values:
[tex]sin30=\frac{4}{x}[/tex]
Multiply both sides by x:
[tex]x(sin30)=x(\frac{4}{x} )\\\\x*sin30=4[/tex]
Divide both sides by sin30°:
[tex]\frac{x*sin30}{sin30} =\frac{4}{sin30}\\\\x= \frac{4}{sin30}[/tex]
Insert the value of x into a calculator:
[tex]x=8[/tex]
OR:
The little red square means that angle is 90º, and the other given angle is 30°. Since every triangle has a measure of 180°, the other missing angle is 60°. The given triangle is a 30°-60°-90° triangle with the following rules:
[tex]long.leg=short.leg*\sqrt{3}\\\\hypotenuse=short.leg*2[/tex]
The hypotenuse is represented by the variable x. We are given the value of the short leg, which is 4. Solve for the hypotenuse:
[tex]h=4*2\\\\h=8[/tex]
Therefore, the value of x is 8.

Charles has 9 times as many red marbles as blue marbles.
If he has 288 more red than blue marbles, how many red marbles does
he have?
Answer:
314 red marblesStep-by-step explanation:
Red = r, blue = b,
r = 9br = b + 288Substitute:
9b = b + 2888b = 288b = 288/8b = 26Red marbles:
r = 288 + 26 = 314The price of a flight was increased by 3% to £650. What was the price before the increase? Give your answer to the nearest penny.
Answer:
£631.07
Step-by-step explanation:
Increasing a value by 3% is the same as taking 103% of it - you have the original price (100%) plus an additional 3% of it. Let's call the original price here p. We're told that after a 3% increase, the price goes up to £650. Put another way: 103% of p is £650. In equation form:
[tex]1.03p=650[/tex]
To solve for p, we can simply divide both sides of our equation by 1.03 to get
[tex]p=650/1.03\approx631.07[/tex]
So our orignal amount, to the nearest penny, was £631.07

£631.07

Answer:
Well I think It's undefined
Step-by-step explanation:
m = y2 - y1/x2 - x1
= 6-6/-9-(-9)
= 6-6/-9+9
m = 0/0
Answer:
slope is indeterminate
Step-by-step explanation:
Given (- 9, 6) and (- 9, 6) ← that is a single point
No line is formed by a point , thus the slope is indeterminate

Answer:
y = 5/6x + 4
Step-by-step explanation:
y = mx + b
b = 4 because when x = 0, y = 4
m = (y2 -y1) / (x2 - x1)
where two points on the equation are (x1, y1) & (x2, y2)
Let's pick points (6,9) & (-6,-1)
m = (-1 - 9) / (-6 - 6)
m = -10 / -12 = 5/6
What are the 5 positive integers that have a mode of 2 and 4, a median of 4 and a mean of 5
Answer:
10 i belive
Step-by-step explanation:
Hence, the five positive integers are 2, 2, 4, 4, 13.
What is a mean , median and mode?Mean- The arithmetic mean of a given data is the sum of all observations divided by the number of observations.
Median-The value of the middlemost observation, obtained after arranging the data in ascending or descending order, is called the median of the data.
Mode-The value which appears most often in the given data i.e. the observation with the highest frequency is called a mode of data.
Step by Step Solution:According to the question , it can be concluded that the total no. of observations are 5.
So , Let n=5
Let the integers be a, b, c, d and e
The question says that mode(s) are 2 and 4.
This indicates that 2 and 4 both have occurred more than once , and both have same frequency since both are modes.
Since we have only 5 integers , and 2 and 4 both are modes , so both these numbers have possibility to occur only twice.
Hence , it becomes , a=2 , b=2 , c=4 , and d=4
Hence we can say that out of five required integers ,four of them are 2 and 4.
Further , we are given that mean is 5.
therefore , using formula:
Mean = Sum of Observations / Number of observations(n)
Mean= (a+b+c+d+e) / 5
5 = (2+2+4+4+e) / 5
5 = (12+e)/5
Multiplying both sides by 5 , we get :
25 = 12+e
e=25-12
Hence , e = 13
So, the five positive integers are 2, 2, 4, 4, 13.
