Answer:
x=7
Step-by-step explanation:
The two lines indicate that it is an isosceles triangle. This means that the bottom two angles and lengths are the same.
To work this out you would first minus 104 from 180, this gives you 76. Then you would multiply 25 by 2, which gives you 50. This is because the angles are the same. Then you would add 50 to 76, which gives you 126. Then you would multiply 9 by 2, which gives you 18. This is because it is an isosceles triangle and the bottom two sides are the same. Then you would divide 126 by 18, which gives you 7.
1) Minus 104 from 180.
2) Multiply 25 by 2.
3) Add 50 to 76.
4) Multiply 9 by 2.
5) Divide 126 by 18.
6) 
<u>Answer Checking:</u>
<u></u>
To check your answer you would work backwards. First you would multiply 7 by 18, which gives you 126. Then you would minus 50 from 126, which gives you 76. Then you would add 104 to 76, which gives you 180.
1) Multiply 7 by 18.
2) Minus 50 from 126.
3) Add 104 to 76.
<u>Because it is a triangle the internal angles all add up to 180. And so if your answer is 180 then the steps are correct.</u>
Answer:
V=378 inch³
Step-by-step explanation:
The package is in the shape of a cuboid. The volume of a cuboid is given by :
V = lbh
l=length, b=breadth and h=height
Area of base = 54 inch²
Height of box, h = 7 in
It means that, volume of the package is :
V = 54 × 7
V=378 inch³
So, the volume of the package is 378 inch³.
78
step by step explanation:
first: divide 600 and 15
answer to 600/15: 40
second: divide 3120 and 40
final answer: 78
Mrs. Benson has 184 math assignments left to grade.
<u>Step-by-step explanation:</u>
Here we have , Mrs. Benson has graded 46 math assignments but has 80% of the assignments left to grade.We need to find Mrs. Benson has how many math assignments left to grade. Let's find out:
Let total Number of math assignments be x , So According to question 46 math assignments are graded & 80% are left i.e.
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Now , Assignments left to grade is :
⇒ 
⇒ 
Therefore , Mrs. Benson has 184 math assignments left to grade.
