A triangle has sides that are 3, 7, and squareroot 57. Is the triangle a right triangle?
Answers
Answer:
my answer is no because for a right angle triangle the sum of the squares of the other two sides is equal to the square of the longest side
3²+7²=9+49=58
(√57)²=57
57≠58 it's not a right angle triangle
assume the sides to be a,b and c
a=3 b=7 c=√57
by Pythagoras theorem
a²+b²=c²
3²+7²=√57²
but 58≠57
hope it's clear

Answer:
B. x = 2√11
Step-by-step explanation:
The square of the length of the diagonal is ...
d² = 6² + 8² = 36 +64 = 100
Then the length of x is found from ...
d² +x² = 12²
x² = 144 -100 = 44 . . . . . subtract d²
x = √44 . . . . . . take the square root
x = 2√11

11) Nick & John ordered burritos & tacos for lunch. Nick
ordered 3 burritos & 4 tacos for $11.33. John ordered 9
burritos & 5 tacos for $23.56. Find the cost of one
burrito & one taco.
Answers
Answer:
taco: $1.49 each
burrito: $1.79 each
Step-by-step explanation:
Let b = cost of one burrito
t = cost of one taco
(1) 3b + 4t = 11.33 (2) 9b + 5t = 23.56
Multiply (1) by -3 and add to (2) -9b - 12t = 33.99
- 7t = - 10.43
t = 1.49
3b + 4(1.49) = 11.33
3b + 5.96 = 11.33
3b = 5.37
b = 1.79

There are 640 calories in 4 scoops of ice cream. At this rate, how many calories would there be in 9 scoops of ice cream?
Answers
Answer:
1,440 calories
Step-by-step explanation:
Divide 640 by 4 to get how many calories there are per scoop.
640 calories ÷ 4 scoops = 160 calories per scoop
Then, we can multiple 160 by 9 to get the calories in 9 scoops.
160 calories per scoop × 9 scoops = 1,440 calories per 9 scoops

Marissa can run 1 mile in 10 minutes.
How many miles can she run in a half
hour?
(If there is extra information, identify it. If
there is not enough information, tell what information is needed.
Answers
Answer:
3 miles
Step-by-step explanation:
if she can run at a constant speed for 30 minutes, then it is 3 miles. But, if there is some reason that she cannot run at the same rate as she did for one mile, the answer is unknown.
Because if you notice that half an hour is 30 minutes then you multiply 1 mile and 10 minutes by 3 and you’ll get 3 miles in 30 minutes.
1mile/10minutes x 3 = 3 miles in 30 minutes

A triangle has sides with lengths of 44 meters, 55 meters, and 77 meters. Is it a right triangle?
Answers
Answer:
no it is not a right triangle because the lengths add up to 176 and a right triangle should add up to 190.
Step-by-step explanation:
The side measures of the triangle does not form a right triangle.
What is a triangle?A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.
For the given situation,
The side lengths of the triangle are 44 meters, 55 meters, 77 meters.
For the triangle to be a right triangle, one interior angle should be 90°.
Based on the sides, by Pythagoras theorem,
Square of long side = sum of square of other two sides
⇒ [tex]77^{2}=44^{2} +55^{2}[/tex]
⇒ [tex]5929=1936+3025[/tex]
⇒ [tex]5929\neq 4961[/tex]
Hence we can conclude that the side measures of the triangle does not form a right triangle.

Emily walked around 2 parks. One measures 54 feet by 38 feet and other measure 32 feet by 22 feet. How much did she walk?
Answers
Answer:
292 feet
Step-by-step explanation:
If Emily walked round the two rectangular parks, she walked round the perimeter of the parks.
the total distance she walked can be determined by calculating the perimeter of each of the park and adding the perimeters together
Perimeter of a rectangle = 2 x ( length + breadth)
Perimeter of the first park = 2 x (54 ft + 38 ft) = 184 ft
Perimeter of the second park = 2x (32 + 22) = 108 ft
Sum of the perimeters = 184 ft + 108 ft = 292 ft
