Answer:

$Solution,\\Circumference=5\pi m\\Diameter(d)=5\pi /\pi =5m\\Radius(r)=5m/2=2.5m\\Now,\\Area=\pi r^{2} \\Area=\pi *(2.5m)^{2} \\Area=\pi *6.25m^{2} \\Area=6.25\pi m^{2}$

Answer:

100

Step-by-step explanation:

add all the number together 3 + 4 + 2 +1=10

250/10=25

then times 25 with the 4 number at the top

25 times 4 =100

so there is 100 blue pencils

I need help with some tutorverse questions, thanks!

Answer:

11. c

12. c

Step-by-step explanation:

11. Since Angle RST = 60 degrees, Angle RTS = 60 degrees.

Triangle STU is a right triangle, so Angle STU and Angle SUT are both 45 degrees.

Angle RTS + Angle STU + Angle UTQ = 180 degrees

60 + 45 + Angle UTQ = 180

Angle UTQ = 180 - 105

= 75 degrees

12. Using the corresponding angles theorem, x = 45 degrees and y = 35 degrees.

x + y

45 + 35

The water in a river moves south at 10 mi/hr. A motorboat travels due east at a speed of 20 mi/hr relative to the shore. Determi

weeeeeb [17]

Answer:22.36 mi/hr

Step-by-step explanation:

Given

water in a river moves south at $(V_w)10 mi/hr$

motorboat travels due to east at a speed of $(V_b)20 mi/hr$

Velocity of boat relative to the moving water $V_{bw}$

$V_{bw}=V_b-V_w$

$V_{bw}=20i-(-10j)=20i+10j$

Magnitude of $V_{bw}=\sqrt{20^2+10^2}=\sqrt{500}$

$V_{bw}=10\sqrt{5} \approx 22.36 mi/hr$

$tan\theta =\frac{10}{20}$

$\theta =26.56^{\circ}$ with the x axis.

Graph each equation rewrite in slope-intercept form first if necessary.Y=-1/3x+4

kati45 [8]

To graph the linear equation, follow the steps below.

Step 01: Find one point of the line.

To do it, choose a x-value and find its corresponding y-value.

Let's choose x = 0.

Substituting x in the equation to find y:

$\begin{gathered} y=-\frac{1}{3}x+4 \\ y=-\frac{1}{3}*0+4 \\ y=0+4 \\ y=4 \end{gathered}$

First point: (0, 4).

Step 02: Find another point of the line.

Let's choose x = 3.

Substituting x in the equation to find y:

$\begin{gathered} y=-\frac{1}{3}*3+4 \\ y=-\frac{1}{3}*3+4 \\ y=-\frac{3}{3}+4 \\ y=-1+4 \\ y=3 \end{gathered}$

Second point: (3, 3).

Step 03: Plot the two points and connect them to draw the graph.

The graph is shown below:
