Answer: A = 24 units^2
Step-by-step explanation: If you cut the shaded region in half it's two rectangles so you have to find the area of it using the formula to find the area of a rectangle.
A = (w)(l) A = (6)(4) A = 24 units^2
Find the gradient of the line segment between the points (6,-4) and (10,-10). Give your answer in its simplest form.
Answers
Answer:
To calculate the gradient of a straight line we choose two points on the line itself. The difference in height (y co-ordinates) ÷ The difference in width (x co-ordinates).

Let ABC be an isosceles triangle with AB = AC and ∠BAC=30°. Side AB and the median AD contain points Q and P respectively (points P and Q are not at point A) in such a way that PC=PQ. Find m∠PQC.
Answers
Answer:
15°
brainlest
Step-by-step explanation:
Since P is on the median of ΔABC, it is equidistant from points B and C as well as from C and Q. Thus, points B, C, and Q all lie on a circle centered at P. (See the attached diagram.)
The base angles (B and C) of triangle ABC are (180° -30°)/2 = 75°. This means arc QC of the circle centered at P has measure 150°. The diameter of circle P that includes point Q is defined to intersect circle P at R.
Central angle RPC is the difference between arcs QR and QC, so is 180° -150° = 30°. Inscribed angle RQC has half that measure, so is 15°. Angle PQC has the same measure as angle RQC, so is 15°.
Angle PQC is 15°.

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day.
We can solve this problem in one single step, I'll start off with that.
We can first figure out what it says and make an algebraic equation. We can see what language the question uses and elaborate on that to create our equation.
[tex]5x-5<6x+2[/tex]
We can use algebra to simplify the equation so that we can solve for it.
[tex]-5<x+2\\-7<x\\x>-7[/tex]
We can check if this is correct by testing a few numbers from that range, I'll take -5 and 2.
[tex]5(2)-5<6(2)+2?\\10-5<12+2?\\5<14[/tex]
We've proven that 2 is working.
[tex]5(-5)-5<5(-5)+2?\\-25-5<-25+2?\\-30<-23[/tex]
We've also proven that -5 works.
We can now say that we've solved the problem, the solution of the problem would be x>-7.

What does the rational form of the ratio a:b look like?
Answers
The rational form of a ratio is the ratio represented as a fraction (or quotient)
The rational form of the ratio a : b is a/b
The ratio is given as a : b (pronounced a ratio b)
This is properly represented as:
[tex]\mathbf{Ratio = a : b}[/tex]
To convert to rational form, means that we express the ratio as a fraction.
So, the ratio becomes
[tex]\mathbf{Ratio = \frac a b}[/tex] (pronounced a divided by b)
Hence, the rational form of the ratio a : b is a/b

Step-by-step explanation:
To calculate the value of x we must first understand the total value of all angles in a triangle.
Sum of all angles in a triangle = 180 degrees
That said, we need to write an equation for the total number of degrees in the triangle and solve for x
This will be as follows:
(13x+2)+(5x-7)+(3x-4)=180
The we combine the like terms. This will be as follows:
(13x+5x+3x)+(2-7-4)=180
Simplify further to get
21x-9=180
Simplify further by collecting all like terms on one side of the equal. This will entail the addition of 9 on each side of the equal sign as follows:
21x-9+9=180+9
you will find 21x=189
Simplify further by dividing both sides of the equal sign by 21 to solve for x
21x/21=189/21
Therefore x=9
The sides forming the right angles and hypotenuse of a right angled triangle are x cm, (2x + 2) cm and (3x – 2) cm respectively. Calculate the perimeter of the triangle.
Answers
Answer:

Step-by-step explanation:
Perimeter is the sum of all the sides:
(x) + (2x + 2) + (3x - 2)
Add like-terms:
6x + 2 - 2 = 6x
Perimeter = 6x

Applying the properties of similar triangles, the other side lengths of ΔDEF are: B. 9 and 12
Properties of Similar Triangles:
The ratio of the corresponding sides two triangles that are similar to each other are the same/equal.Given that ΔABC and ΔDEF are similar triangles, therefore:
Let, a = 6, b = 8, and c = 12 be the sides of ΔABC.Let, x, y, and z be the sides of ΔDEF.Let z = 18Thus:
a/x = b/y = c/z
Substitute6/x = 8/y = 12/18
Find x using 6/x = 12/18:
6/x = 12/18
Cross multiplyx = [tex]\frac{18 \times 6}{12}[/tex]
x = 9
Find x using 8/y = 12/18:
8/y = 12/18
Cross multiplyx = [tex]\frac{18 \times 8}{12}[/tex]
x = 12
Therefore, applying the properties of similar triangles, the other side lengths of ΔDEF are: B. 9 and 12

Step-by-step explanation:
the surface area (base area plus side wall) of a cone is, when we have the radius and the length of the slanted side wall :
SA = pi×r×(r + l)
in our case here
r = half of the diameter = 12/2 = 6 m
l = 13.4 m
so, we have
SA = pi×6×(6 + 13.4) = pi×6×19.4 = 365.6813849... m²

Mei is making fruit punch.
She makes the fruit punch by mixing fruit juice and lemonade in the ratio 1 : 3.
The fruit juice costs £1.80 per litre.
The lemonade costs 75p per litre.
Work out the total cost of making 16 litres of fruit punch.
Answers
Answer:
16.2p (If lemonade is .75p, if not substitute in the equation below)
Step-by-step explanation:
In 4 liters, there would be 3 liters of lemonade and 1 liter in juice.
I am assuming 75p is meant to be .75p
So 4 liters costs: (1 x 1.8) + (3 x .75) = 4.05
We need 16 so: 4.05 x 4 = 16.2
