Answer:
√17
Step-by-step explanation:
Since it's a square, the area will simply be the side length squared. Therefore, we can take the square root of 17 to get the exact length. Since 17 is a prime number, it cannot be simplified any further.

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|
|4.7+(-11.2)|
|11.2-4.7|
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

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.
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

Drag descriptions and equations to the table to complete the explanation.
please look at picture attached,
thank you
Answer:
Given = 6 x 0 = 0
Step 2 = Substitute. Any number plus its opposite equals 0 (10 +-10)
Step 3 = Use the distributive property
Step 5 = Subtract 60 from both sides
Step 6 = Simplify to solve for 6 x -10
9/5-(-6/10= reduced to the simplest form
Answer:
Since it is a double negative, you add the two together. First, you must find the LCD though. Which is 10. So you multiply the left side by 2. This comes out to 18/10 - (-6/10) but since there's two negatives, you add them, so it's 18/10 + 6/10 = 24/10 = 12/5
Step-by-step explanation:
The answer is 12/5 (top is explaining how I got there.)
Answer:
12/5
Step-by-step explanation:
9/5 - (-6/10)
Subtracting a negative is like adding
9/5 + 6/10
Simplify 6/10 by dividing the top and bottom by 2

18. Prime numbers are closed under subtraction.
True or false
Answer: False
=======================================
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.

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?
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

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

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

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
[tex] = > x = \frac{172}{4} [/tex]
=> x = 43
As,
We got value of x as 43 so,
x° = 43°
x° = 43 + 8 = 51°
x° = 2 × 43 = 86°

Hope it is helpful.....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 .
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
xD= (xa*1+xd*2)/ (2+1)= ((-4)*1+2*2)/3=0
