The number between both of them is 1250
1. Add 1000+1500=2500
2.Divide it by 2
3.That equals your answer which is 1250

$the \ number \to \frac{1000+1500}{2}=\frac{2500}{2}\to\boxed{\boxed{1250}}$

astraxan [27]

Answer:

It will take 9 hours with 4 painters to paint 720 feet of fence.

Step-by-step explanation:

Given that,

The time needed to paint a fence varies directly with the length of the fence

$t\propto l$ .......(1)

and inversely with the number of painters

$t\propto \frac1P$ .....(2)

Combination of (1) and (2) is

$t\propto \frac lP$

where t represents time, $l$ represents length of fence, P represents number of painters.

Again we can write the above equation as

$\frac{t_1}{t_2}=\frac{\frac{l_1}{l_2}}{\frac{P_1}{P_2}}$

$\frac{t_1}{t_2}=\frac{l_1P_2}{l_2P_1}$

Given that,

It takes 7 hours with 2 painters to paint 280 feet of fence .

We need to find time to paint 720 feet of fence with 4 painters.

$t_1$ =7 hours, $l_1$ =280 feet, $P_1$ =2,

$t_2$ =? , $l_2$ = 720 feet, $P_2$ =4

$\therefore \frac{7}{t_2}=\frac{280\times 4}{720\times 2}$

$\Rightarrow \frac{t_2}{7}=\frac{720\times 2}{280\times 4}$

$\Rightarrow {t_2}}=\frac{720\times 2\times 7}{280\times 4}$

$\Rightarrow t_2=9$

It will take 9 hours to paint 720 feet of fence with 4 painters.

Answer:

the answers are 12.5, 5, 2, 0.8 and 0.32

Step-by-step explanation:

2(0.4)^-2

=2(6.25)

= 12.5

2(0.4)^-1

= 2(2.5)

=5

2(0.4)^0

=2(1)

=2

2(0.4)^1

=2(0.4)

=0.8

2(0.4)^2

=2(0.16)

=0.32

12. Find the measure of each interior angle of triangle QRT.

Veseljchak [2.6K]

Answer:

$\angle QRT=125.6\°$

$\angle RTQ=6.4\°$

$\angle TQR=48\°$

Step-by-step explanation:

It is important to remember that, by definition, the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

In this case we can idenfity that the angle $17x$ is an exterior angle of the triangle QRT. Then:

$17x=\angle RTQ+\angle TQR$

Where:

$\angle RTQ=2x\\\\\angle TQR=48\°$

Substituting values and solving for "x", we get:

$17x=2x+48\\\\17x-2x=48\\\\15x=48\\\\x=3.2$

Then:

$17x=17(3.2)=54.4\°\\\\\\\angle RTQ=2(3.2)=6.4\°$

The sum of the interior angles of a triangle is 180°, therefore:

$\angle QRT+\angle RTQ+\angle TQR=180$

Solving for $\angle QRT$ , we get:

$\angle QRT=180-48-6.4=125.6\°$
