Answer:
9 pizzas total were bought for a party. Maya ate 1/3 of a pizza. John ate 4/9 of the same pizza. How much pizza is left?
Answer: 74/9 or 8.2
Step-by-step explanation:
first add 4/9 and 1/3 since it's in parenthesis
4/9+1/3
they need to have the same denominator, use the LCM (which is 9)
multiply 1/3 by 3 to achieve the LCM
4/9+3/9
add together numerators
7/9
subtract 7/9 from 9
9/1-7/9
get 9 to achieve the LCM (which is 9 again)
multiply 9/1 by 9
81/9 minus 7/9= 74/9

➷ Multiply 40 by 70 ( a cheat way is to do 7 x 8 and then add 2 zeroes on the end)
40 x 70 = 2800
Then do 40 x 2 ( do 4 x 2 and then add a zero)
40 x 2 = 80
Add these two values together:
2800 + 80 = 2880

Answer:
Part A) The triangles ABC and EDC are similar by AAA, because the three internal angles are equal in both triangles
Part B) The width of the river is about
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
Part A) we know that
In this problem , triangles ABC and CDE are similar by AAA, because its corresponding angles are congruent
so
-----> by vertical angles
-----> is a right angle
-----> the sum of the internal angles must be equal to 180 degrees
Part B) we know that
The triangles ABC and EDC are similar -------> see Part A
therefore
substitute the values and solve for AB
Answer:
Step-by-step explanation:
X + 61° = 90° {right angle}
X = 90° - 61°
X = 29°
90 degrees that will be your answer hope I helped
