The answer should be 95in^2
Explanation:
You’re essentially just finding the area of all the shapes on the triangle and adding them together.
Area of a triangle = 1/2•b•h
Area of a square = l•w or just s2
The area of the triangles given what we have in the diagram can be found with
1/2•5•7 = 17.5
There are 4 triangles so you multiply 17.5 by 4 which gives 70
The base of the triangle (the square) = 25
70+25=95

Step-by-step explanation:
By looking at the graph, the line at x = 4 is equals to y = 7
Answer:
120 4-digit numbers.
Step-by-step explanation:
For the numbers to be divisible by 5 they must end in 5.
So the total number of first 3 digits of the 4-digit number are given by the
number of permutations of 3 from the numbers 1,2,3,4,6 and 7 (6 digits)
= 6P3
= 6! / (6-3)!
= 6*5*4
= 120.
Answer:
8.8
Step-by-step explanation:
Alright so since you know the length of the side opposite the 27 degree angle and you need to find the hypotenuse, you'll use sin (opposite/hypotenuse) . so you do sin 27= 4/x and then when you do these trigometric ratios something my geo teacher taught me is that if the variable is in the denominator then you have to do the length of the side you know /sin/cos/tan of whatever angle you know. so here you insert in your calculator 4/sin 27 (make sure ur calculator is in degree mode you can check this by doing sin 30 and seeing if it equals 1/2 and if it doesnt you need to search online on how you do degree mode) and you get 8.8108. which rounds to 8.8
