What is the angle VXU?<br>Plzzz help ​
maxonik [38]

Answer:

∠ VXU = 105°

Step-by-step explanation:

the chord- chord angle VXU is half the sum of the arcs intercepted by the angle and its vertical angle.

The sum of the arcs in a circle = 360° , so

UV = 360° - (130 + 60 + 90)° = 360° - 280° = 80°

Then

∠ VXU = \frac{1}{2} (80 + 130)° = 0.5 × 210° = 105°

Evaluate 1 whole number 2/5 + 3/4 and give your answer to one significant figure​
ehidna [41]

Answer:

The answer is

<h3>2 to 1 significant figure</h3>

Step-by-step explanation:

1 \frac{2}{5}  +  \frac{3}{4}

To solve the question first convert the mixed fraction to an improper fraction

That's

1 \frac{2}{5}  =  \frac{7}{5}

So we have

\frac{7}{5}  +  \frac{3}{4}

Find the LCM of the fractions

The LCM of 5 and 4 is 20

That's

\frac{7}{5}  +  \frac{3}{4}  =  \frac{7(4) + 3(5)}{20}  =  \frac{28 + 15}{20}

=  \frac{43}{20}

= 2.15

We have the final answer as

<h3>2 to 1 significant figure</h3>

Hope this helps you

Answer:

Step-by-step explanation:

y = 3x + 4

Plugin x = 3 in the equation,

y = 3*3 + 4

 = 9 + 4

y = 13

Plugin x = 4 in equation,

y = 3*4 + 4

  = 12 + 4

y = 16

Plugin x = 5 in the equation,

y = 3*5 + 4

  = 15 + 4

y = 19

2) y =x - 7

Plugin x = 10 in the equation

y = 10 - 7

y = 3

Plugin x = 15 in the equation

y = 15 - 7

y = 8

Plugin x = 20 in the equation

y = 20 - 7

y = 13
