80% of how many games is 32

Nina [5.8K]

Answer:

<em>The total number of games is </em><em>40.</em>

Step-by-step explanation:

Let us assume the total number of games played is x.

So 80% of total number of games is,

$=x\times \dfrac{80}{100}$

$=x\times \dfrac{4}{5}$

As it is given as 32, so

$\Rightarrow x\times \dfrac{4}{5}=32$

$\Rightarrow x=32\times \dfrac{5}{4}$

$\Rightarrow x=8\times 5$

$\Rightarrow x=40$

Therefore, the total number of games is 40

Find the equation of the line shown.

kipiarov [429]

Answer:

The line passes through (1,1) and (3,2). Therefore, its equation is

$y -1 = \frac{2-1}{3-1} (x-1)\\or, y-1 = \frac{1}{2} (x-1)\\or, 2y-2 = x-1\\or, x-2y-1+2=0\\or, x-2y+1=0$

A piece of property lies between two parallel streets as shown. m<1=(2x+6)°,and m<2=(3x+9)°. What is the relationship betw

kolezko [41]

The angles are supplementary angles

The measure of angle m<1 and m<2 are 72 and 108 degrees respectively

Find the diagram attached. From the figure, the sum of the angles m<1 and m<2 are supplementary

Given the following angles

m<1 = 2x + 6

m<2 = 3x + 9

Since both angles are supplementary, hence;

2x + 6 + 3x + 9 = 180

5x + 15 = 180

5x = 180 - 15

5x = 165

x = 165/5

x = 33

Get the measure of m<1;

m<1 = 2x + 6

m<1 = 2(33) + 6

m<1 = 66 + 6

m<1 = 72degrees

Get the measure of m<2:

m<2 = 180 - m<1

m<2 = 180 - 72

m<2 = 108degrees

Hence the measure of angle m<1 and m<2 are 72 and 108 degrees respectively

Tyler and Pearl went on a 20km bike ride that lasted for 3 hours. Because of steep hills or the trail, they walked for most of t

noname [10]

Answer: 1 hour

Step-by-step explanation:

Let the distance they walked be $d_1$ in time $t_1$ and the distance they walked be $d_2$ in time $t_2$ ,then

Walking speed= $\frac{d_1}{t_1}=4$

$\\\Rightarrow\ d_1=4t_1$

Riding speed= $\frac{d_2}{t_2}=12$

$\\\Rightarrow\ d_2=12t_1$

Also the total time taken=3 hours

∴ $t_1+t_2=3\\\Rightarrow\ t_2=3-t_1$ ...(1)

Since the total distance= 20 km

∴ $d_1+d_2=20\\\Rightarrow4t_1+12t_2=20\\\Rightarrow4t_1+12(3-t_1)=20..............[\text{from (1)}]\\\Rightarrow4t_1+36-12t_1=20\\\Rightarrow-8t_1=-8\\\Rightarrow\ t_1=1$

Thus, the they spent 1 hour time in walking.
