need help on #4 !!!!

Answer:

7/18

Step-by-step explanation:

Area of ABED = 49

Side lengths are 7, its a square

Since AD = 7, and AG = 9, DG = 2

DE = 7 and 2 x 7 = 14

14 is the area of the small blue region.

AC = 10, and AB = 7, so BC = 3

CF = BE = 7

3 x 7 = 21

21 is the area of the big blue region.

21 + 14 = 35

Area of the whole shape is 9 * 10 = 90

35/90 = 7/18

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

Step-by-step explanation:

Only the third number is divisible by 3. So the HCF is 2 * 5 = 10

That's the most that is common between all three numbers.

The first two only have a HCF of 100. Nothing else goes into both of them.

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:

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

9/5 + 3/5

Let other be x

Using angle sum property

[tex]\\ \rm\Rrightarrow x+7+90=180[/tex]

[tex]\\ \rm\Rrightarrow x+97=180[/tex]

[tex]\\ \rm\Rrightarrow x=180-97[/tex]

[tex]\\ \rm\Rrightarrow x=83°[/tex]

Answer:

I don't know to be honest

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

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 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

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: 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.

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

yd= (ya*1+yd*2)/ (2+1)= (2*1+ 5*2)/3=12/3=4

Answer:

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
