what is the perimeter, in feet (ft), of a right triangle which has an area of 12 ft^2 and one leg that has a length of 4 ft?

Answers

Answer:

P = (10 + 2√13) ft ≈ 17.21 ft

Step-by-step explanation:

A = 12 ft² - area of triangle

a = 4 ft, b - legs of right triangle

c - hypotenuse (third side of triangle)

A = ¹/₂ ab

12 = ¹/₂•4•b

12 = 2b

b = 6 ft

from Pythagorean theorem:

a² + b² = c²

4² + 6² = c²

c² = 16 + 36

c = √52 = 2√13 ft

The perimeter: P = a + b + c

P = 4 + 6 + 2√13 = (10 + 2√13) ft ≈ 10 + 7.21 = 17.21 ft

Answers

2.2 with the 2 repeating

Answer:

[tex]\frac{20}{9}[/tex] or 2 [tex]\frac{2}{9}[/tex]

Step-by-step explanation:

1. Set up the problem : 2 ÷ [tex]\frac{9}{10}[/tex]

2. Since 2 is a whole number we can give it a denominator of 1, transforming the problem to: [tex]\frac{2}{1}[/tex] ÷ [tex]\frac{9}{10}[/tex]

3. Change the division sign into a multiplication sign.

[tex]\frac{2}{1}[/tex] × [tex]\frac{9}{10}[/tex]

4. Find the reciprocal by swapping the numerator and denominator on the second fraction

[tex]\frac{2}{1}[/tex] × [tex]\frac{10}{9}[/tex]

5. Multiply fractions

[tex]\frac{2}{1}[/tex] × [tex]\frac{10}{9}[/tex] = [tex]\frac{20}{9}[/tex] or 2 [tex]\frac{2}{9}[/tex]

A football team lost 19 yards on each of their first three plays. What was their overall change in yardage?

Answers

Answer:

Let's say the set of downs starts at the 20 yard line (maybe the kicking team kicked deep, the receiving team took a knee and so play starts at the 20).

Ok - we're at the 20. First down - they advance 5 yards. So we're now at the 25. We can write that mathematically as:

So the second play they get sacked deep and lose 6 yards. So we subtract 6:

−

So what's the change in yardage for the 2 plays? We are on the 19 and started at the 20, so we can write:

−

and this makes sense because we know we advanced 5 and fell back 6:

One angle of an isosceles triangle is known to be 68°. What would be one of the other angles?

Answers

Answer:

52 degrees

Step-by-step explanation:

Iscosceles trangle adds up to 180 degrees.

two sides are the same.

180-68= 112

112 divided by 2 = 52

the three sides are 52, 52, 68

The measure of one of the other angles would be x = 44 degree.

What is a triangle?

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

Isosceles triangles have two angles that are equal.

We are given that One angle of an isosceles triangle is known to be 68°.

Since the two equal angles are 68

We have the angles 68, 68, and an unknown angle x

Now add to 180

68+68+x = 180

136+x=180

x =180-136

x =44

Roberto and Sandy are playing a rounding game. Roberto says the number 634. Sandy rounds Roberto's number to the nearest hundred. What number does Sandy say?

Answers

The answer would be 600

Reason: If you are rounding up to the nearest hundred then anything 650 or higher, it would be 700 but anything 649 and lower, it would be 600.

It would be 600 because we are rounding to the nearest hundred of 634 so we look to the right and since the three is lest than five we dont round up leaving it 600.
