Answer:
The y-intercept is (0, 1/2)
The x-intercept is (0, -8)
Answer:
138.16 in²
Step-by-step explanation:
The surface area SA of the cone is the sum of the base area B and the lateral area LA. The lateral area is half the product of the circumference and the slant height. The radius is half the diameter, so is 4 inches.
SA = B + LA
= πr² + (1/2)(2πrh) . . . . where h is the slant height
= (πr)(r +h)
Filling in the numbers, you have ...
SA = (3.14)(4 in)(4 in + 7 in) = 3.14×(44 in²) = 138.16 in²
38.9 is the answer. because it is rounded to the nearest tenth.
Answer:
Step-by-step explanation:
Move the decimal point in the divisor and dividend.
Turn the divisor (the number you’re dividing by) into a whole number by moving the decimal point all the way to the right. At the same time, move the decimal point in the dividend (the number you’re dividing) the same number of places to the right.
Place a decimal point in the quotient (the answer) directly above where the decimal point now appears in the dividend.
Divide as usual, being careful to line up the quotient properly so that the decimal point falls into place.
Line up each digit in the quotient just over the last digit in the dividend used in that cycle.
X=Y-7
4X+2Y=62
4(Y-7)+2Y=62
4Y-28+2Y=62
6Y=62+28
6Y=90
Y=90/6
Y=15
Larger number^
X=15-7=8
Smaller number^
PROOF:
4*8+2*15=62
32+30=62
62=62
Hope this helps.
