Answer:
4/7
Step-by-step explanation:
When you multiply by fractions you multiply the numerators and denominators
4/1 x 1/7
Anything that doesnt have anything under it always has a 1 as its denominator
Answer:
to the right
Step-by-step explanation:
you're looking for values over 10 to make the inequality true, meaning the numbers has to go larger, you'd draw the line vertically at 10, then shade to the right.
Answer:
A regular pentagon has 5 sides and 5 lines of symmetry.
Step-by-step explanation:
The number of lines of symmetry in a regular polygon is equal to the number of sides.
Answer: the top of the ladder is 20ft below the ground.
Step-by-step explanation:
The ladder makes an angle, θ with the ground thus forming a right angle triangle with the wall of the house.
The length of the ladder represents the hypotenuse of the right angle triangle.
The ground distance between the base of the house and the base of the ladder represents the adjacent side of the right angle triangle.
Therefore, to determine the height at which the ladder rest on the building, x, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
25² = x² + 15²
625 = x² + 225
x² = 625 - 225 = 400
x = √400 = 20 ft
Get them to have the same number on the bottom by finding the lowest common number when multiplying which would be multiplying them by each other by you also have to multiply the top number so for 1/5 multiply 1 & 5 by 3 and you get 3/15 then the same for 1/3 but multiply by 5 so it'll be 5/15 add them and you get 8/15 so you have 7/15 left.
