Which expression represents the distance between 4.7 and -11.2 on the number line?

Drag and drop the correct expression into the box.

|4.7+(-11.2)|

|11.2-4.7|​

Answers

Answer:

1st option

Step-by-step explanation:

Calculate the distance using the absolute value function, that is

distance = | 4.7 - (- 11.2) | = | 4.7 + 11.2 | = | 15.9 | = 15.9

or

distance = | - 11.2 - 4.7 | = | - 15.9 | = 15.9

Answer:

$7.10

Step-by-step explanation:

Step 1: We make the assumption that 35.5 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=35.5$.

Step 4: In the same vein, $x\%=20$.

Step 5: This gives us a pair of simple equations:

$100\%=35.5(1)$.

$x\%=20(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

Step 7: Taking the inverse (or reciprocal) of both sides yields

Hope this helps <3

Answer:

x° = 43°x° = 51°x° = 86°

Step-by-step explanation:

Given,

x + ( x + 8) + 2x = 180° [Since angle sum property of triangle]

=> x + x + 8 + 2x = 180

=> 4x + 8 = 180

=> 4x = 180 - 8

=> 4x = 172

=======================================

Explanation:

We simply need one counterexample to disprove the original claim.

The values 5 and 11 are prime, but 11-5 = 6 is not prime.

We see that taking two primes, and subtracting them, leads to some value outside the set of primes. Therefore, the set of primes is not closed under subtraction.

Peyton needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 4 hours and charged her $77 for parts. The total was $497. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.

Answers

Answer:

105 per hour = x

Step-by-step explanation:

You subtract the parts cost of 77 from the total first.

497 - 77 = 420

Then you divide the 420 by 4 to get the unit rate per hour.

420/4

= 105

How far is weather station A from the storm?
44.6 miles
19.7 miles
42.2 miles
31.2 miles

Answers

Answer: Choice D)  31.2 miles

This value is approximate.

============================================================

Explanation:

Let's focus on the 48 degree angle. This angle combines with angle ABC to form a 90 degree angle. This means angle ABC is 90-48 = 42 degrees. Or in short we can say angle B = 42 when focusing on triangle ABC.

Now let's move to the 17 degree angle. Add on the 90 degree angle and we can see that angle CAB, aka angle A, is 17+90 = 107 degrees.

Based on those two interior angles, angle C must be...

A+B+C = 180

107+42+C = 180

149+C = 180

C = 180-149

C = 31

----------------

To sum things up so far, we have these known properties of triangle ABC

angle A = 107 degreesside c = side AB = 24 milesangle B = 42 degreesangle C = 31 degrees

Let's use the law of sines to find side b, which is opposite angle B. This will find the length of side AC (which is the distance from the storm to station A).

b/sin(B) = c/sin(C)

b/sin(42) = 24/sin(31)

b = sin(42)*24/sin(31)

b = 31.1804803080182 which is approximate

b = 31.2 miles is the distance from the storm to station A

Make sure your calculator is in degree mode.

The weather station A is 31.2 miles from the storm

From the triangle shown:

m<B = 90° - 48°

m<B = 42°

m<A = 17° + 90°

m<A = 107°

m<A + m<B + m<C = 180° (Sum of angles in a triangle)

107° + 42° + m<C = 180°

m<C = 180° - 149°

m<C = 31°

The distance between the weather stations A and B = 24 miles

That is, AB = 24 miles

The storm is at point C

The length AC is found by using the rule of sines:

[tex]\frac{sinC}{AB}=\frac{sinB}{AC} \\\\\frac{sin31}{24}=\frac{sin42}{AC} \\\\\frac{0.515}{24} = \frac{0.669}{AC} \\\\0.02146=\frac{0.669}{AC}\\\\AC=\frac{0.669}{0.02146} \\\\AC=31.2 miles[/tex]

The weather station A is 31.2 miles from the storm

The coordinates of the vertex A of Triangle ABC are ( -4 ,2) and D the mid-point of BC are ( 2 , 5 ).Find the
coordinates of the centroid .

Answers

Answer:

(0,4)

Step-by-step explanation:

The line AD is a median, because D is the midpoint of BC.

The centroid is the point of intersection of three medians of triangle, we don't need to depict any another median, because we know that centroid divide each median in ratio 2:1 from the vertices of a triangle from which a median was depicted. That's obvious that the median AD was depicted from A. Let the point of centroid be M. AM:MD is 2:1. So we should find the coordinates of D

Distribute the figure into three rectangles, namely, A, B and C as shown in the picture.

We know that,

Area of a rectangle

= 2(l + b)

Now,

Consider rectangle A,

Length = 25in

Breadth = 15in

Hence,

Area = 2 (l + b)

= 2 (25 + 15)

= 2 (40)

= 80in²

Consider rectangle B,

Length = 25 - 7 = 18in

Breadth = 16in

Hence,

Area = 2 (l + b)

= 2 (18 + 16)

= 2 (34)

= 68in²

Consider rectangle C,

Length = 11in

Breadth = 24in

Hence,

Area = 2 (l + b)

= 2 (24 + 11)

= 2 (35)

= 70in²

Area of the figure

= Area of rectangle A + Area of rectangle B + Area of rectangle C

= 80in² + 68in² + 70in²

= 218in²

Stewart's car can hold a maximum of g gallons
in its gas tank, and gas costs c dollars per
gallon. If the car currently has 2 gallons of gas
in the tank, what is the cost, in dollars, to fill up
the rest of the tank?

Answers

2c because 2 times c, which is the amount it costs for each gallon, is 2c

The formula that gives us the cost, in dollars, to fill up the rest of the tank is,

Cost = (g - 2) × c

Given that;

The car currently has 2 gallons of gas and can hold a maximum of g gallons,

Hence, the amount of gas needed to fill the tank is,

(g - 2) gallons.

If the cost of gas is c dollars per gallon, the total cost to fill up the rest of the tank can be calculated by multiplying the number of gallons needed by the cost per gallon:

Cost = (g - 2) × c

Thus, the formula that gives us the cost, in dollars, to fill up the rest of the tank is,

Cost = (g - 2) × c
