Answer:

8\frac{1}{4}

46 \frac{1}{3}

Step-by-step explanation:

To Find the perimeter you have to add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width).

\frac{7}{8} +\frac{7}{8}+3\frac{1}{4}+3\frac{1}{4} =8\frac{1}{4}

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

10 \frac{1}{3} +10 \frac{1}{3}+12\frac{5}{6} +12\frac{5}{6}=46 \frac{1}{3}

A. The function must be non-linear because he constantly changes his speed and pauses at some places. For it to be linear he would have to be going at a constant rate the entire time.

B. Plot the point (20, 1.2), draw a line from (0,0) to it. Then plot (30, 1.2), because he stays there for 10 minutes. Now plot the point (60, 2.5) because it takes him 30 minutes to walk 1.3 miles to the park. Then plot the point (75, 2.5) because he stays there for 15 minutes. Lastly, plot the point (120, 5) for his return home. Be sure to connect these points together with lines.

A pole that is 2.6 m tall casts a shadow that is 1.03 m long. At the same time, a nearby tower casts a shadow that is 46.25 m lo
photoshop1234 [79]

Answer:

Therefore the height of the tower is 116.75 m.

Step-by-step explanation:

Given that a pole that is 2.6 m tall casts a shadow that is 1.03 m long.

Here the height of a object directly proportional to the shadow. It means

Height of the object ∝ shadow

Height of the object= k.shadow

[k is the proportional constant.]

\Rightarrow \frac{h}{s} =k    [Height of object is denoted by h and shadow is denoted by s]

Then,

\frac{h_1}{s_1} =k       [h₁ is the height of the pole and s₁is the length of the shadow]

Again for the tower

\frac{h_2}{s_2}=k      [h₂ is the height of the tower and s₂ is the length of the shadow]

Therefore,

\frac{h_1}{s_1}=\frac{h_2}{s_2} =k

\Rightarrow\frac{h_1}{s_1}=\frac{h_2}{s_2}............(1)

Given h_1 = 2.6 m  ,s_1=1.03m  and   s_2=46.25m

Putting the value of h_1,s_1 and s_2  equation (1)

\frac{2.6}{1.03}=\frac{h_2}{46.25}

\Rightarrow h_2 \times1.03= 2.6\times 46.25          [cross multiplication]

\Rightarrow h_2 = \frac{2.6\times 46.25}{1.03}

\Rightarrow h_2= 116.75

Therefore the height of the tower is 116.75 m.

Зу = - 2x + 12 how do you graph this equation ​
evablogger [386]

Explanation:

Start out by dividing all terms by 3 to put the equation in PROPER Slope-Intercept Form:

\displaystyle \frac{3y}{3} = \frac{-2x + 12}{3} \\ \\ y = -\frac{2}{3}x + 4

Now, starting from the y-intercept of [0, 4], you do \displaystyle \frac{rise}{run}by either moving two blocks <em>north</em> over three blocks <em>west</em> or two blocks <em>south</em> over three blocks <em>east</em> [<em>west</em> and <em>south</em> are negatives].

I am joyous to assist you anytime.
