Which equation can be used to solve for the value
of x?
Answer:
the orange one
Step-by-step explanation:
the bottom angles are gonna be the same and a triangle is 180 degrees total so
- 11x - 19 = - 41
solve for x
Answer:
-11x -19 = -41
We need to add 19 to both sides then divide to find x.
_____________________
1)) so -11x -19 + 19 = -41 + 19
2)) -11x = -22
3)) -11x/-11 = -22/-11
x = 2
GL!
(side note, i dont usually ask, but it would be great if you could mark me brainliest so I can level up <33)
Answer:
x = 2
Step-by-step explanation:
-11x - 19 = -41
Add 19 to both sides of the equation:
-11x - 19 + 19 = -41 + 19
-11x = -22
Divide both sides by -11
-11x/-11 = -22/-11
x = 2

The original rectangle is 120 centimeters. Calculate the length of a rectangle that is 72% shorter.
What is the answer
Answer:
33.6 cm
Step-by-step explanation:
120 x 0.72 = 86.4
120 - 86.4 = 33.6
The new rectangle which is 72% shorter is 21.6 centimeters.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given The original rectangle is 120 centimeters.
And the new rectangle is 72% shorter or (100 - 72)% = 18% of the original rectangle which is,
= (18/100)×120 centimeters.
= 21.6 centimeters.

: Scottie is standing next to a lighthouse on the edge of a cliff overlooking the ocean. The cliff is 30 meters above sea level, and the lighthouse has a height of 15 meters. There is a man fishing in a boat directly below Scottie who has hooked a fish that is 10 meters below the surface of the water.
Complete question :
Scottie is standing next to a lighthouse on the edge of a cliff overlooking the ocean. The cliff is 30 meters above sea level, and the lighthouse has a height of 15 meters. There is a man fishing in a boat directly below Scottie who has hooked a fish that is 10 meters below the surface of the water.
a. Use positive and negative numbers to represent the locations in relation to sea level.
Scottie =
Top of the lighthouse =
The boat =
The fish =
b. How far is Scottie from the fish?
meters.
Answer:
Scottie = +30 m
Lighthouse = +45m
Boat = 0
Fish = - 10m
40 m
Step-by-step explanation:
Scottie = 30m ( height of the cliff) since he is standing on it's edge
Top of lighthouse = since, lighthouse is located on top of the cliff ; height of cliff + height of light house = (30 + 15) = 45m
The boat = 0 (on the surface of water) ; this is the sea level surface or point
The fish = - 10 m (10 meters below the water surface).
Distance between scottie and fish :
30 m - ( - 10m)
30m + 10m
= 40 m

Given the function h(x)=-x^2+x+4, determine the average rate of change of the function over the interval −1≤x≤5.
Answer:
average rate of change of h(x) on −1 ≤ x ≤ 5 is then 5
Step-by-step explanation:
change in h(x)
average rate of change = ------------------------
change in x
Calculate h(x) at the interval endpoints: -1 ≤ x ≤ 5, and then subtract h(5) from h(-1):
h(5) = (5)² + 5 + 4 = 34
h(-1) = (-1)² -1 + 4 = 4
change in h(x) = 34 - 4 = 30
change in x: 5 - (-1) = 6 30
average rate of change of h(x) on −1≤x≤5 is then ------------- = 5

A pendulum is swinging back and forth. After ttt seconds, the horizontal distance from the bob to the place where it was released is given by \qquad H(t) = 7 - 7 \cos \left(\dfrac{2\pi (t-2)}{20}\right)H(t)=7−7cos( 20 2π(t−2) )H, left parenthesis, t, right parenthesis, equals, 7, minus, 7, cosine, left parenthesis, start fraction, 2, pi, left parenthesis, t, minus, 2, right parenthesis, divided by, 20, end fraction, right parenthesis. How often does the bob cross its midline? Give an exact answer
Answer:
Every 10 seconds
Step-by-step explanation:
The bob crosses its midline whenever cos(2π(t-2)/20)=0.
Since cosθ=0 when θ=±π/2 + 2πn, we can find then the bob crosses its midline by solving:
2π(t-2)/20 = ±π/2 + 2πn
t-2 = ±5+20n
The solutions are when t = -3, 7, 17, 27, 37, ...
Therefore, the bob passes its midline every 10 seconds.

Find (f x g)(2)? Thanks
Let me break this up.
Note: (f o g)(2) = f(g(2)).
Note: g(2) = (2, 2) means when x is 2 y is 2.
In other words, g(2) is 2.
We know that f(g(2)) = f(2).
You can see that f(2) = -3. This is given in the point (2, -3).
So, f(g(2)) = -3.
Done.
Peter and Jane have some money in the ratio 1:3
Jane has £12 more than Peter how much money does Peter have?
Answer:
Peter has 6 dollars.
Step-by-step explanation:
The ratio is 1:3, meaning Jane has 3x more money than Peter. Or, Peter has 1/3 as much money as Jane. You know that Jane has 12 dollars more than Peter so you can think of scenarios. Because it is a 1/3 the answer for Peters money has to be 1/3 of Janes, so Peter has 6 dollars, and Jane has 12 more, so Jane has 18 dollars.

Charlotte invests £5000.
The bank pays 10% interest for the first year and then y% every year after that.
After three years, Charlotte has £5610.55
Calculate y
Answer:
y = 1%
Step-by-step explanation:
From the formula;
Interest; i = PRT/100
P = £5000
R = 10%
After 1 year, we have;
i = 5000 × 10 × 1/100 = £500
Amount is now; 5000 + 500 = £5500
Since interest rate is now y% every year after the first one, then;
After 2nd year;
i = (5500 × y × 1)/100
i = 55y
So amount is now;
5500 + 55y
After 3rd year, interest is now;
i = (5500 + 55y) × y × 1/100
i = 55 + 0.55y²
Amount is now;
(5500 + 55y) + (55 + 0.55y²)
Since she has £5610.55 after 3 years, then;
(5500 + 55y) + (55 + 0.55y²) = 5610.55
0.55y² + 55y + 5555 - 5610.55 = 0
0.55y² + 55y - 55.55 = 0
From quadratic formula, y = 1%
