Each cup equals 8 ounces so the 4 times 8 will eqaul 32. The next part will be multiplying 1/4 by 8/1, so as to multiply a fraction by a fraction and make it simpler. By removing the common factor of 4 from 8 and 4, you are left with 1/1 times 2/1, which ultimately equals 2 ounces. The complete answer will be 34 ounces, a whole number.
a test to see if it is a function is a vertical line test, if you draw a straight line and the line intersects at 2 points, it is not a function.
in this case, (-2,-2) is an open hole, which means the value where it is placed is just around that value so not exact.
the vertical line test would work if it was a closed hole, and one or both points (-2,3) and (-2,-2) would have to be removed.
the mistake that deshawn made was that he mixed up the vertical line test with horizontal instead and has deduced that since a horizontal line has intercepted both points, they must be removed.
this graph is, in fact, a function since the open hole is not exactly under (-2,3)
Answer:
C
Step-by-step explanation:
Two negative signs make a positive number. So -(-4) makes 4. I know it sounds weird, but thats what schools teach. Hope this helps!
Answer:
63
Step-by-step explanation:
the numbers are in ratio 7 : 9 = 7x : 9x ( x is a multiplier )
given the sum of the numbers = 112 , then
7x + 9x = 112 , that is
16x = 112 ( divide both sides by 16 )
x = 7 , then
9x = 9 × 7 = 63 ← value of larger number
Answer:
m<C = 66°
Step-by-step explanation:
Perpendicular bisector, AB divides angle CAD into two equal parts. Therefore:
(5x + 9)° = (7x + 3)°
Solve for x
5x + 9 = 7x + 3
Collect like terms
5x - 7x = -9 + 3
-2x = -6
Divide both sides by -2
x = 3
✔️m<C + m<CBA + m<BAC = 180° (sum of triangle)
m<C + 90° + (7x + 3)° = 180 (substitution)
Plug in the value of x and solve
m<C + 90 + 7(3) + 3 = 180
m<C + 90 + 21 + 3 = 180
m<C + 114 = 180
m<C = 180 - 114 (Subtraction property of equality)
m<C = 66°
