if two angle of a right angle triangle are in the ratio 1:2,find them
Answer:
let the angles be x,2x
=>90+x+2x=180
=>3x=90
=>x=30
so, the angles are 30,60
let the angles be x,2x
=>90+x+2x=180
=>3x=90
=>x=30
so, the angles are 30,60
please help me, what is this
Answer:
Proof:
In ΔCDB
∵ The sum of all angles of triangle = 180°
∴ m∠B + m∠C + m∠D = 180°
R3. Their sum = 180 (They form straight angle)
S4. ∠B + ∠A = 180°
R5. Triangle angle sum theorem (Sum of all angles of triangle = 180°)
If x + y = 10 and x - y = 4, find the value of x² - y²
Answer:
x²-y² = 40
Step-by-step explanation:
Factorising x²-y²:
x²-y² = (x+y)(x-y)
This is due to the property that states:
a²+b² = (a+b)(a-b)
Substituting the given values into the above equation:
x²-y² = (10)(4)
= 40
Hence, x²-y² = 40

Khan academy What is the slope of the line?
Answer:
Slope: 3/4
Step-by-step explanation:
If you want the equation for the line:
y = (3/4)x - 1
However, this is how you find the slope:
You want to find any two point on the graph, however, it's easier if it touches exactly where two number meet. For example I chose:
(0,-1) and (2,4)
Now just find the change in y, and divide it by the change in x
change in y = 3
change in x = 4
So your slope is 3/4

3/4

Answer:
1) 9
2) 8
3) 5
4) 72
5) 40
6) 3
Step-by-step explanation:
1) 5 times 9 equals 45, then you add 5 to get 50.
2) -2 times 8 equals -16, minus 3 is the same as adding a -3 to get -19
3) 7 times 5 equals 35, plus 1 to get 36.
4) 72 divided by 6 equals 12, minus 10 to get 2.
5) 40 minus 14 equals 26, divided by 2 to get 13.
6) 3 times 3 equals 9, minus 5 to get 4 then multiplied by 4 to get 16 as your final answer.

9514 1404 393
Answer:
yes
Step-by-step explanation:
When the variation is direct, the ratio of y to x is a constant (the constant of proportionality).
19/5 = 22.8/6 = 26.6/7 = 30.4/8 = 3.8
The table is another representation of the proportional relation ...
y = 3.8x
Yes, the variation is direct.

Which of the algebraic expressions below is equal to 28?
Select all that apply.(ANSWER ONLY IF YOU KNOW!)
A) (34)(20)×2
B) (24÷4)(7)
C) 9(7−3)–8
D) (3+4)⋅(22+3)
Answer:
ITS C
Step-by-step explanation:
9(7−3)−8
=(9)(4)−8
=36−8
=28
Answer:
C.
Step-by-step explanation:
9(7-3)-8
according to PEMDAS, we have to do the parenthesis first. so
9(4) - 8
then
36 - 8
which gives us 28.
Hope this helped! (:

by factoring out the GCF what is 12r-4?
Answer:
4(3r-1)
Step-by-step explanation:
GCF is the highest number that divides exactly into two or more numbers. In this case, it would be 4 because it's the largest number that both 12 and 4 divide into.
f(x)=2x-3;find f (0), and f(x-3)
Answer:
f(x) = 2x – 3
f(0) = 2(0) – 3 = -3
f(1) = 2(1) – 3 = 2 – 3 = -1
(f(0) + f(1))/2 = (-3 - 1)/2 = -4/2 (f(0) + f(1))/2 = - 2
on a sunny day liam decided to walk to his grandmother's house. After walking for a while at a rate of 3 mph, Liam realized that it might start raining, so he decided to take a taxi the rest of the way. The taxi traveled at a speed of 30mph. If he arrived 2 hours before he started, what distance did liam traveled by taxi?
The answer is ten. The formula for calculating speed is as follows:
Speed = distance × time. Knowing the distance and time units is required to calculate the speed units.
Explain about the speed?A bicycle that travels 30 meters in two seconds, for example, is moving at a rate of 15 meters per second. The speed of an object in motion varies frequently (for example, a car may travel down a street at 50 km/h, then slow to 0 km/h, and then accelerate to 30 km/h).
The rate at which a distance changes over time is referred to as speed. It has a dimension of time and distance. As a result, the SI unit of speed is formed by combining the fundamental unit of time and the fundamental unit of distance. As a result, the SI unit of speed is the meter per second (m/s).

Answer: y=3x
Step-by-step explanation:
We want an equation of the form y=mx+b where m is the slope and b is the y-intercept (the value of y when x is 0).
The slope: From the point (0,0), the braph goes to point (2,6). Slope is the rise (y) over the run(x): (6/2) or 3. The slope, m, is 3. b, the y-intercept, is 0. y is 0 when x is 0.
y=3x
Someone help me please
Step-by-step explanation:
Q6
answer A, as x² is the regular parabolic curve up. and x²-3 just shifts this curve down by 3 units. and that is what we need, as the extreme point of the curve is a bit below the x-axis, and therefore has a negative y value.
Q7
answer C, as this curve is the complete opposite of the curve in Q6.
it is the regular parabolic curve but down. that means -x².
but the extreme point is a bit above the x-axis (and has therefore a positive y value). -x²+3 shifts the parabolic curve up by 3 units.
Q8
answer A again. the functional values are only positive (the whole curve is above the x-axis). so, C and D are therefore wrong.
and between A and B we need to remember, that a negative exponent means 1/...
in case of B 1/(2^x).
and that would mean for large positive x we would get very small values for y.
but we see the opposite. for large x we also get large y.
so, it is 2^x (answer A).
