Answer:
85 students are in the ninth grade
Step-by-step explanation:
17 + 23 = 40
200/40 = 5
17 *5 = 85
<span>You have to sum up three concepts, the cost before sales tax, the sales tax and the tip. The price before sales tax $11.75; the sales tax is the price times 8%, which $11.75 *8% = $11.75*8/100 = $11.75*0.08 = 0.94; and the itp is $2. Then, the equation is w = 11.75 + (0.08)(11.75) + 2, and the result is 14.69. So, the true statements are B and D.</span>
To find the surface area, we want to find the area of each side, then add them all up together:
Area of base=lw
A=(5)(5)
A=25 cm²
Area of triangle=1/2bh
A=(1/2)(5)(12.5)
A=31.25 cm²
Since the 4 triangles have the same area, we can multiply the area we found by 4 and then add the area of the square:
SA=(4)(31.25) + 25
SA=125+25
SA=150 cm²
X=3.5 add 10 and divide by 8
Answer:
x = 9
Step-by-step explanation:
We know that the angles are equal.
105 = 12x - 3
108 = 12x
9 = x
x = 9
