Answer:
21°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180 for the other angle
other angle = 180° - (90 + 69)° = 180° - 159° = 21°

£240 is divided between Sara , Gordon and Makachy so that sara has twice as much as gordon and Gorgon gets three times as much as Makachy .How much does Gorgon get?
Answer:
Gordon gets £72
Step-by-step explanation:
£240....together
Sara.....2*(3x)
Gordon.....3x
Makachy......x
2*(3x)+3x+x=240
6x+3x+x= 240
10x=240/10
x=24
Gordon 3*24= 72
Which equation represents a linear function that is proportional?
Answer:
A) f(x) = 1/3x
Step-by-step explanation:
You can rule out B and C-
B is a quadratic function, seeing as how x is being squared, and C is an absolute value function. Neither of these are linear so you don't have to worry about it here.
That leaves us with A and D, which are both linear.
Linear functions usually take the form of f(x) = mx + b. In a proportional linear function, b = 0.
So with that in mind, you should see that the b value for f(x) = 2x + 11 is 11, which should rule D out as well.
That leaves you with f(x) = 1/3x. As you can see, there's no b value in this function, which means b = 0 and the function is proportional.
Hope this helped :D

Una recta atraviesa el punto (4,-6) Y tiene una pendiente igual a 5/4
Ayúdenme con este problemaaa porfavor
Answer:
y=5/4x-11
Step-by-step explanation:
tenemos un punto (4,-6) y una pendiente equal a 5/4.
usa la ecuación y=mx+b (m es la pendiente, b es el y interceptar)
porque sabemos la pendiente es 5/4, ahora mismo la ecuación es:
y=5/4x+b
en el punto, x=4, y=-6
podemos sustituir los números en la fómula para resolver b
-6=4(5/4)+b
-6=5+b
-11=b
entonces,
la ecuación de la recta es y=5/4x-11

The radius of a circle is 9 times the radius of a smaller circle. The area of the smaller circle is 50 square centimeters. What is the area of the larger circle?
Answer:
Let R = radius of big circle
r=radius of small circle
A1=Area of small circle
A2=Area of big circle
R=9r
A1=50cm^2
A1=pi*r*2
A2=pi*R^2
A2=pi*(9r)^2
A2=81*pi*r^2
A2=81*A1
A2=4050cm^2
Hence the big circle has area of 4050cm^2
Step-by-step explanation:
The answer is 4050 cm²
What is the area and circumference of a circle?The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.
Given here: The radius of a circle is 9 times the radius of a smaller circle. And area of the smaller circle is 50 cm² then let the area of the larger circle be x
π9²/π1² =x/50
x=4050
Hence, The answer is 4050 cm²

hat is the slope-intercept form of the linear equation 4x + 2y = 24?
Answer:
y = - 2x + 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
4x + 2y = 24 ( subtract 4x from both sides )
2y = - 4x + 24 ( divide all terms by 2 )
y = - 2x + 12 ← in slope- intercept form

Step-by-step explanation: Well if she sold 110 hamburgers on tuesday for $545 That is a simple division equation (545/110). After dividing the answer would be how much each hamburguer cost on its own ( 4.954545454545455), you would then multiply that by the number of hamburgers she sold (53) and get your answer. (262.5909090909091) I am not quite sure where she wants us to round the answer to. so I just did the tens place.
