The base of a triangle is 18 cm and its height is 7w-1 cm. Find the expression for the triangles area
Answers
Answer:
Area = 9(7w -1) cm²
Step-by-step explanation:
Area of a triangle is given by the expression,
Area = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]
From the picture attached,
Base of the triangle = 18 cm
Height of the triangle = Vertical distance of the third vertex from the base joining other two vertices = (7w - 1)
Area = [tex]\frac{1}{2}(18)(7w-1)[/tex]
= 9(7w - 1) square cm
Therefore, expression for the area of the given triangle will be,
Area = 9(7w -1) cm²

Answers
Answer:
area: 1070
perimeter: 434 units
Step-by-step explanation:
area:
- use pythagoream theorem to find the height, which is gonna be 84
- from there, you're gonna wanna find the area of the rectangle and then the two triangles. the way i do it is by just finding the area of the rectangle first, 100x84 = 8400, and then finding the area of the triangles (35x84/2 = 1470 and 20x84/2 = 840)
- you have the area of all shapes, now just add them together (8400+1470+840 = 10710)
perimeter:
just add all the lengths given together.

Answers
Answer:
44.68 m²
Step-by-step explanation:
Area of a sector = θ/360*πr²
Where,
θ = 80°
r = 8 m
Plug in the values into the equation
Area of the sector = 80/360*π*8²
= 44.6804288 ≈ 44.68 m² (nearest hundredth)
fig., QR is a common tangent to the given circles,
touching externally at the point T. The tangent at T
meets QR at P. If PT = 3.8 cm,then find the length of QR.
Answers
Answer:
QR = 7.6 cm
Step-by-step explanation:
By theorem of tangents drawn from an external point to a circle,
"Tangents drawn from an external point to a circle are equal in measure"
By this property,
PQ = PT = 3.8 cm
And PR = PT = 3.8 cm
Since, QR = PQ + PR [By segment addition postulate]
QR = 3.8 + 3.8
QR = 7.6 cm
Ms. Nelson has 8 pounds of ground beef. She is making burgers that are ¼ pound each.
Answers
Answer:
she will make 32 burger patties.
One way:
8 x 4 = 32
the fraction will get reversed so it turns to 4.
Second way(basically the same as the first way):
8 divided by 1/4 = 8 x 4= 32
You just have to divide 8 by 1/4. The fraction gets reversed in divisions so it turns to 4.
Answer:
ok the answer is...
Step-by-step explanation:
32!!
the reason for this is because 1/4 + 1/4 + 1/4 + 1/4 = 4!
so do that again all over again 8 times and you have your answer.
The length of the base of an isosceles triangle is x. The length of a leg is 2x - 2. The perimeter of the triangle is 51. Find x.
Answers
Answer:
x = 11
Step-by-step explanation:
x + 2(2x-2) = 51
x + 4x - 4 = 51
5x - 4 = 51
5x = 55
x = 11
Answer:
x = 11
Step-by-step explanation:
2x - 2 + 2x - 2 + x = 51
5x - 4 = 51
5x = 55
x = 11

You have 7 donuts to share evenly among you and your three brothers. Which equation describes how many donuts each of you will receive? Choose 1 answer: Choose 1 answer: 7÷4= 7/4 7÷3=7/3 3÷7=3/7 4÷7=4/7
Answers
Answer:
7/3
Step-by-step explanation:
Since you have seven donuts to share with three brothers, you can calculate that each one of you will get 2 donuts and there will be a spare one left. You know that you also have to share that one so you split it into thirds. 7/3 = 2 1/3

A number is less than one-fourth the sum of eight times the number and four.
Answers
Answer:
Assume the number is X. What is given can be written as the following:
X < (1/4)*(8X+4)
Multiply 4 on both sides
4X< 8X+4
Subtract 4X+4 from both sides
-4 < 4X
-1<X i.e., X>-1 the number is greater than -1.
