a) 20° b) 40° c) 60°

Answers

Answer 1

Answer:

Here,

given, angle B = 80 degree

in ABC triangle, AB = AC

that means angle B = angle C

so angle C must be 80 degree

Step-by-step explanation:

I guess, the options are wrong

or,

may the question asked for angle angle A

which will be = 180- (80+80) = 180 - 160 = 20 degree (option a)

6a If 17.5% of the students were 7, then 100% would be 100/17.5 times 7 which equals 40.
Therefore, there are 40 students in total.


6b. The amount of students present would be the amount absent taken away from the amount of the students in the class, which is. 40 - 7 = 33. So 33 students were present.

7. If the hat cost $18 dollars in the 10% sale, the percentage is now 90% of the original price (100-10=90). Therefore, if $18 equals 90%, then 100% (the original price) would be 100/90 times 18 which equals 20. So the original price is $20.

8. Apply the same principle as question 7. 76kg is 95% so his original weight is 100/95 times 76 which equals 80kg. Therefore his weight before the decrease is 80kg.

9. Apply the same principle as question 7 and 8. 185l is 88% so the amount of water before evaporating would be 100/88 times 185 which equals 210.22l. Therefore 210.22l would be left.

The product of three consecutive integers is 3360. What is the sum of the three integers?

Answers

Step-by-step explanation:

let the integer be x .

three consecutive integers : x, x+1, x+2.

according to the problem,.

Let the first of the 3 consecutive numbers be X.

Therefore the second number is (X + 1)

The third number is therefore (X + 2)

The product of the 3 consecutive numbers is:

( X )( X + 1 )( X + 2 ) = 3360 Equation( 1 )

Expanding Equation ( 1 ) gives

X³ + 3X² + 2X - 3360 = 0 Equation (2)

Solve Equation (2 ) which gives the following values for X

X1 = 14

X2 = - 8.5 + i (12.951834)

X3 = - 8.5 - i (12.951834).

the numbers are 14,15,16.

sum is 14+15+16 = 45.

hope this helps you.

The thickness of the sheet of paper in nanometre is 50,000

The sheet of paper is 0.00005 meter thick .

1 nanometre = 1 × 10⁻⁹ meters

1 × 10⁻⁹ meters = 1 nanometre

0.00005 meters = ?

5 The area of a trapezium is 54 cm^2. The length of one of the parallel sides is 8 cm and the height is 6 cm. Find the length of the other parallel side.​

Answers

Answer:

come here if you want to see

The length of the other parallel side is 10 cm.

Trapezium is a quadrilateral (has four sides and four angles) with a pair of parallel sides. The area (A) of a trapezium is given by:

A = (1/2)(a + b)h

where a and b are the length of the parallel sides, h is the height of the trapezium

Given A = 54, a = 8 cm, h = 6 cm, hence:

54 = (1/2)(8 + b)6

8 + b = 18

b = 10 cm

The length of the other parallel side is 10 cm.

find the area of the triangles first:
formula for the area of a triangle is A=bh/2
the base is 12
the height can be found by taking the 13(given) subtracting 5(given) and dividing by 2 which gives you 4 and then just fill in the formula
A= 12•4/2
A=24 then multiply by 2(bc there are two triangles and you get
A=48

now to the area of the rectangle which is just
A=BH you fill it in
A=12•5 solve
A=60
then you add the area of the triangles to the area of the rectangle to get the area of the hexagon
A=48+60
