180 steel rods to be exact
Answer:
2nd graph (in the attached pics)
Step-by-step explanation:
Graphically, the <em>x-intercepts of the graph of a quadratic function are its zeroes. </em>
There can be
- no zeroes (where graph doesn't cut the x-axis at all),
- 1 zero (where graph touches the x-axis at one point only), and
- 2 zeros (where the graph cuts the x-axis at 2 points)
Looking at the figures, the 2nd graph has no real zeroes, <em>because the graph doesn't cut the x-axis at all!</em>

So, the answer is the second graph.
- 4 = 25
First, simplify
to
/ Your problem should look like:
- 4 = 25
Second, multiply both sides by 5. / Your problem should look like: 3p - 20 = 125
Third, add 20 to both sides. / Your problem should look like: 3p = 125 + 20
Fourth, simplify 125 + 20 to get 145. / Your problem should look like: 3p = 145
Fifth, divide both sides by 3. / Your problem should look like: p =
Answer as fraction: p =
Answer as decimal: 48.3333
Answer:
9
Step-by-step explanation:
3/7 multiplied by 21 = 3/7 x 21 = 9 = 3/7 x 21/1 = 63/7 = 9
Or if you can't do the math - Think of a pizza with 21 slices . Now cut this pizza into 7 equal parts. You will find that each part contains exactly 3 slices. Now, eat 3 of these parts. With three slices in each part, you ate 9 slices - which is three sevenths of 21.
Answer:
46 minutes (Answer B)
Step-by-step explanation:
One way of doing this is to realize that it's 14 minutes to 4 p.m. and then another 32 minutes past 4 p.m. Thus, the total elapsed time was
(14 + 32) minutes, or 46 minutes (Answer B)
