Answer:

v = -23/4 = -5 3/4

Step-by-step explanation:

4= - 3/(v+5)

Multiply each side by (v+5)

4 (v+5) = -3

Distribute

4v+20 = -3

Subtract 20 from each side

4v +20-20 = -3-20

4v = -23

Divide by 4

4v/4 = -23/4

v = -23/4

Answer: $500

Step-by-step explanation:

Hi, since both credit options accumulate the same amount of interest:

1000+125x=1300+110x

Solving for x(number of months)  

125x-110x =1300-1000

15x = 300

x =300/15

x= 20 months

Replacing x =25 in one equation:

1000+125x =

1000+125(20)=

1000+2500= $3500

Finally, we have to subtract the amount of the purchase (3000) to the result obtained:

3500-3000=$500

Answer:

4.68 in

Step-by-step explanation:

4.825-0.145=4.68 in

The inside diameter of the pipe is 4.68 inches.

A straight line that runs through the sideways of a body or figure, particularly a circle or sphere, is called as a diameter of a circle or sphere.

Given:

The outside diameter of a pipe is 4.825 inches.

If the pipe wall is 0.145 inches thick,

the inside diameter of the pipe,

= 4.825 - 0.145

= 4.68

Therefore, the diameter is 4.68 inches.

Answer:

volume of water in the tank when it its half full

The capacity of the water tank = (5.04) /2 = 2.52 m³

2,520 litres

Step-by-step explanation:

Dimensions of a water tank:

Length (l) = 2.0 m,

wide (w) = 1.4 m,

Depth (h)= 1.8 m,

Volume of the tank (V)

LWH

2.0m × 1.4m × 1.8 m

= 5.04 m³

= 5.04 × 1000 litres

/* 1m³ = 1000 litres */

5,040 litres

Therefore,

The capacity of the water tank = 5.04 m³

Answer:

495 students

Step-by-step explanation:

The 4 part of the ratio is the number of boys.

Divide the number of boys by 4 to find the value of one part of the ratio.

220 ÷ 4 = 55 ← value of 1 part of the ratio, thus

5 parts = 5 × 55 = 275 ← number of girls

Number of students = 220 + 275 = 495

Answer:

Step-by-step explanation:

[tex]220 \: boys \\ 4:5 = 4 + 5 \\ boys \: = \frac{4}{9} \times x = 220 \\ = \frac{4x}{9} = \frac{220}{1} [/tex]

Answer:

x=35

Step-by-step explanation:

Since a quadrilateral's interior angles add up to 360°, we get this:

360-85-20=360-4x+x

340-85=360-3x

255=360-3x

-105= -3x

Multiply both sides by -1

105=3x

3x=105

Divide both sides by 3

x=35

Answer: The radius and the cord must be perpendicular to each other.

Step-by-step explanation:

A cord is a line from a point of circumference of a circle to another point of the circumference of the circle without passing through the centre.

A radius is a line from the centre of a circle to the circumference of the circle.

When the radius line intersect and bisects a cord of a circle, the radius and the cord must be perpendicular to each other.

Answer:

if in a circle a radius bisects a chord then the radius is perpendicular to the chord,

Answer:

In the figure attached, the solution is shown.  

Step-by-step explanation:

Given the inequality:

|x| < 3

There are 2 solutions:

x < 3 or x > -3

This can be rewritten as follows:

-3 < x < 3

On the number line, this represents all the point between -3 and 3. Notice that -3 and 3 are not included in the solution; that is why there are open circles at these points on the graph.

Answer:

No; the slopes of segment LM and segment LN are not opposite reciprocals

Step-by-step explanation:

slope of LM: (2 - 0)/(2 - 0)  = 1

slope of LN: (-1 - 0)/(2 - 0) = -1/2

Two lines are perpendicular when the multiplication of their slopes is equal to negative one, that is, they are opposite reciprocals. In this case:

slope of LM*slope of LN = 1*(-1/2) = -1/2

The correct option is

No; the slopes of segment LM and segment LN are not opposite reciprocals

slope of LM: [tex](2 - 0)\div (2 - 0)[/tex]  = 1

And,  

slope of LN: [tex](-1 - 0)\div (2 - 0)[/tex]= [tex]-1\div 2[/tex]

Here two lines should be perpendicular at the time  when the multiplication of their slopes is equalivalent to negative one.  

So,  

= slope of LM × slope of LN

P(winning) = 1 / 3

Therefore, P(not winning) = P(losing) :

1 - P(winning) = 1 - 1/3 = 2/3

Probability that shenice will first win on her third try can be interpreted as:

1st try = lose, 2nd try: lose, 3rd try : win

P(losing) × p(losing) × p(winning)

Answer:

b. y=-x+2

Step-by-step explanation:

hi!

the slope intercept form is y=mx+b where m is the slope, and b is the y intercept.

since the y intercept is postive 2, we can first eliminate choices A and C since they show a y intercept of negative 2, not positive 2.

next, we can eliminate d since the line of the graph is going downwards, meaning that the slope or m is negative.

Therefore, the correct answer is b.

u can also use a graphing calculator if youre unsure and plug in each equation and see if it matches with the graph.

Answer:

The yellow trapezoid equals to 6.

Step-by-step explanation:

Assuming that two green items equals to two purple items and one yellow trapezoid, we can make the equation 5+5=2+2+x. Simplifying both sides, we get 10=4+x. If we subtract 4 from both sides and isolate x, we get that x=6.

Answer:

yellow trapezoid = 6

Step-by-step explanation:

since the green crescent equals 5, and there are two on the left side, that would equal 10, so the right side also should equal 10 too. The purple teardrops equal two, and there are two on the right side, so the total of teardrops on the right side is equal to 4. Since both sides need to equal to 10, and we only have 4, we need to find the amount of the yellow trapezoid. To do that you need to subtract 4 from 10, to get 6, which is the amount of the yellow trapezoid.
