Answer: x=12.37 (2 decimal place) and the second box is √153

Step-by-step explanation:

You would have to use pythagoras theorem.

The formula for the short side is x²=c²-b²

The formula with the numbers in it is x²=13²-4²

13²=169

4²=16

x²=169-16

x²=153

To find x on its own you would have to square root 153.

x=12.37 (2 decimal places)

Hope this helps :)

shusha [124]

Answer:

The answer to your question is y = -11/2x - 19

Step-by-step explanation:

Data

Point (-4, 3)

⊥ to the line x- intercept of 22 and y-intercept of -4.

Process

1.- Find the equation of the perpendicular line

This line has passes through the points  (22, 0) and (0, -4)

Slope = \frac{-4 - 0}{0 - 22} = \frac{-4}{-22} = \frac{2}{11}

2.- Find the slope of the new equation

Slope = \frac{-11}{2}    because the lines are perpendicular

3.- Find the equation of the new line

            y - 3 = -11/2 (x + 4)

            y - 3 = -11/2x - 44/2

            y - 3 = -11/2 x - 22

            y = -11/2 x - 22 + 3

            y = -11/2x - 19

Ivenika [448]

Answer:

Carlos rode further on Sunday by 1\frac{51}{56} miles miles.

Step-by-step explanation:

Carlos covered distance on Saturday =\frac{139}{8}

He covered distance on Sunday = \frac{135}{7}

Equivalent fractions:

\frac{139}{8} \times \frac{7}{7}=\frac{973}{56}\\ \frac{135}{7} \times \frac{8}{8}=\frac{1080}{56}

So,\frac{1080}{56}>\frac{973}{56}\\ \frac{135}{7}>\frac{139}{8}

So, He covered more distance on Sunday

Difference between distances =\frac{1080}{56}-\frac{973}{56}=\frac{107}{56}=1\frac{51}{56}

So, Carlos rode further on Sunday by 1\frac{51}{56} miles miles.

Answer:

  26. B(t) = 500·1.075^t; B(6) ≈ $772

  27. G(t) = 70·0.72^t; G(3) ≈ 26 g

Step-by-step explanation:

The equation with the plus sign is used when the value is increasing. The minus sign is used when the value is decreasing. The 'a' in each equation is the initial value.

__

26. B(t) = 500·1.075^t

  B(6) = 771.65

The balance after 6 years is about $772.

__

27. G(t) = 70·0.72^t

  G(3) = 26.127

About 26 grams are left after 3 days.

statuscvo [17]
This can be the equation, if you put it in x and you put it in y. So x plus y is equal to 30,000, 5/100x plus 11 over 100y is equal to 2200. The answer is y is equal to 70, 000 over 6. X = 11000/6
