Answer:
Amount fudge he needs = 23/24 kg
Step-by-step explanation:
Given:
Total fudge wants = 1\(\frac{1}{2}\) = 3/2 kg
His sister gave = 1/6 kg
He make = 3/8 kg
Find:
Amount fudge he needs
Computation:
Amount fudge he needs = Total fudge wants - His sister gave - He make
Amount fudge he needs = 3/2 - 1/6 - 3/8
Amount fudge he needs = 23/24 kg

What is the value of A in this equation? sin(53.2°) = cos(A)
(I need this answer ASAP please)
Answer:
\(A= 35.8\)
Step-by-step explanation:
Given
\(sin(53.2) = cos(A)\)
Required
Find A
In trigonometry
\(sin(\alpha) = cos(\theta)\)
Then
\(\alpha + \theta = 90\)
So, this gives:
\(54.2 + A= 90\)
Make A the subject
\(A= 90-54.2\)
\(A= 35.8\)

According to the angles between intersecting secant and tangent, the value of

angle PQR = 49 degrees
How to solve for angle DFThe value of angle DF is solved using the angles of intersecting secant out side the circle
The theorem give the formula in the form
44 = 1/2 (140 - DF)
88 = 140 - DF
DF = 140 - 88
DF = 52 degrees
Using intersection of tangents, for the second figure
exterior angle = 1/2 (major arc - minor arc)
major arc = 360 - 131 = 229
PQR = 1/2 (229 - 131)

The temperature in a hotel is 21 °C.
The temperature in the hotel is 26,7°C warmer than at the top of the mountain.
The temperature at the top of the mountain is 3.2°C colder than at the bottom of the mountain.
Work out the temperature at the bottom of the mountain.
The temperature at the bottom of the mountain is 50.9 °C.
Let's work through the given information step by step to find the temperature at the bottom of the mountain.
The temperature in the hotel is 21 °C.
The temperature in the hotel is 26.7 °C warmer than at the top of the mountain.
Let's denote the temperature at the top of the mountain as T_top.
So, the temperature in the hotel can be expressed as T_top + 26.7 °C.
The temperature at the top of the mountain is 3.2 °C colder than at the bottom of the mountain.
Let's denote the temperature at the bottom of the mountain as T_bottom.
So, the temperature at the top of the mountain can be expressed as T_bottom - 3.2 °C.
Now, let's combine the information we have:
T_top + 26.7 °C = T_bottom - 3.2 °C
To find the temperature at the bottom of the mountain (T_bottom), we need to isolate it on one side of the equation. Let's do the calculations:
T_bottom = T_top + 26.7 °C + 3.2 °C
T_bottom = T_top + 29.9 °C
Since we know that the temperature in the hotel is 21 °C, we can substitute T_top with 21 °C:
T_bottom = 21 °C + 29.9 °C
T_bottom = 50.9 °C
Therefore, the temperature at the bottom of the mountain is 50.9 °C.

A school bus is moving 26.8 m/s on flat ground when it begins to accelerate at 4.73 m/s^2. How much time does it take to travel 95.1 m?
The school bus will take 5.34 seconds to travel 95.1 m if the bus is moving 26.8 m/s on flat ground when it begins to accelerate at 4.73 m/s².
What is a quadratic equation?Any equation of the form \(\rm ax^2+bx+c=0\) where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
\(\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}\)
We have:
A school bus is moving 26.8 m/s on flat ground when it begins to accelerate at 4.73 m/s².
From the second equation of motion:
\(\rm s = u + \dfrac{1}{2}at^2\)
We have given:
s = 95.1 m
u = 26.8 m/s
a = 4.73 m/s²
\(\rm 95.1 = 26.8 + \dfrac{1}{2}(4.73)t^2\)
The above equation is a quadratic equation:
After simplification:
\(\rm \dfrac{4.73}{2}t^2=68.3\)
\(\rm t^2=28.879\)
t = 5.373 seconds ≈ 5.34 seconds
Thus, the school bus will take 5.34 seconds to travel 95.1 m if the bus is moving 26.8 m/s on flat ground when it begins to accelerate at 4.73 m/s².

which equation represents the relationship between the X values and Y values in the graph
The equation which represents the relationship between X values and Y values can be found by deriving the equation of line using slope intercept form. The equation of line is 3x - 5y = 25.
How to find equation of line using slope intercept form?
Equation of line using slope intercept form is y = mx + b
where m is slope of the line and b is y-intercept
The slope intercept can be used to form equation of line using two points on the line.
According to the given question:
The two points which lie on the line are (x, y) = (5, -2) and (x', y') = (0, -5)
Slope of the line m = y' - y/x' - x
= (-5 +2)/(0 - 5)
= 3/5
Now y intercept b = y - mx
= -2 - (3/5. 5)
= -5
Therefore the required equation of line is y = 3/5x - 5
On simplifying further 3x - 5y = 25

Answer:
b = 90°
Step-by-step explanation:
Angles a, b, c total 180°, and angles a and c are complementary, meaning they total 90°. The measure of angle b is ...
b = 180° -90°
b = 90°
__
All of the angle measures are ...
a = 90° -c = 90° -56° = 34°
b = 180° -90° = 90°
c = given = 56°
d = given = 124°

Step-by-step explanation:
We know that the sum of the angles of a triangle is 180
HCA + CAH + AHB = 180
80+ CAH + 90 = 180
Combine like terms
170 + HAC = 180
HAC= 180-170
HAC = 10
We also know that HCA + ACB is a straight line so it adds to 180
HCA + ACB = 180
80+ACB = 180
ACB = 180-80
ACB = 100
Since ACB is isosceles the base angles have the same measure so CAB = ABC
We know that the sum of the angles of a triangle is 180
CAB + ABC + ACB = 180
Replacing ABC with CAB
CAB + CAB + 100 = 180
2CAB + 100 =180
2 CAB = 180-100
2 CAB = 80
Divide by 2
CAB = 80/2
CAB = 40
Now find HAB
HAB = HAC + CAB
= 10 + 40
= 50
