Answer:

Step-by-step explana

1- R == 11

D=2R = 22

2-D =30

R= 0.6D = 15

3- D = 26

R= 0.5D= 13

4 - R= 7

D= 2R = 14

Give the function 12x-16y=-48 determine the x-and y intercepts of the graph

Sholpan [36]

For the x-int, replace y with 0
for the y-int, replace x with 0

x-int:
12x-16(0)=-48
12x=-48
x=-4

y-int:
12(0)-16y=-48
-16y=-48
y=3

Find the measure of 2 and 4 if 1=122° and 3 = 58°

aalyn [17]

Answer:

Due to lack of details, I can come up with several possible answers

if 2 is opposite from ∠3, then ∠2 = 58°

if 2 is opposite from ∠1, then ∠2 = 122°

if 4 is opposite from ∠3, then ∠4 = 58°

if 4 is opposite from ∠1, then ∠4 = 122°

What are 26 divide by 4,340

mart [117]

$\frac { 26 }{ 4,340 } \\ \\ =\frac { 26 }{ 4\cdot { 10 }^{ 3 }+3\cdot { 10 }^{ 2 }+4\cdot { 10 }^{ 1 } } \\ \\ =\frac { 26 }{ 10\left( 4\cdot { 10 }^{ 2 }+3\cdot { 10 }^{ 1 }+4 \right) } \\ \\ =\frac { 2\cdot 13 }{ 2\cdot 5\left( 4\cdot { 10 }^{ 2 }+3\cdot { 10 }^{ 1 }+4 \right) } \\ \\ =\frac { 13 }{ 5\left( 4\cdot { 10 }^{ 2 }+3\cdot { 10 }^{ 1 }+4 \right) }$

$\\ \\ =\frac { 13 }{ 5\left( 400+30+4 \right) } \\ \\ =\frac { 13 }{ 2,000+150+20 } \\ \\ =\frac { 13 }{ 2,170 }$
