I need help figuring out what the area is of the given shape

Answer:

1/2

Step-by-step explanation:

Yes, I agree.

Make a graph [tex]y=-\frac{4}{5}x+\frac{2}{5}[/tex]

The point of intersection of the line with x-axis is the solution of [tex]-\frac{4}{5}x+\frac{2}{5}=0[/tex]

Multiply by 5 on both sides, get -4x + 2 = 0, x = 2/4 = 1/2

The solution is 1/2.

Answer:

5/2

Step-by-step explanation:

I used coordinate (-4, -2) and (-2, 3)

Slope=change in y/change in x

-2-3=-5

-4-(-2)=-2

-5/-2=5/2

Answer:

[tex]\frac{-5}{-2}[/tex] or 2.5

Step-by-step explanation:

(-2,3) and (-4,-2)

[tex]\frac{-2-3}{-4-(-2)}[/tex] ==> [tex]\frac{-5}{-2}[/tex] ==> 2.5

Hope that helps!

Answer:

  $56.02

Step-by-step explanation:

The account balance after 10 years is given by the future value formula:

  FV = P(1 +r)^t . . . . . principal P invested at rate r compounded annually for t years

  FV = $200(1 +0.025)^10 ≈ $256.02

The amount in excess of the original investment is the interest earned:

  $256.02 -200.00 = $56.02 . . . . interest earned in 10 years

Answer:

$256.02

Step-by-step explanation:

Here is the formula: 200(1.025)^10.

The .025 is the percentage of the interest, and the 1 is the money you already have (which is 200). The ^10 is the 10 years.

If you take the (1.025)^10, you'll get an incredibly large number, 1.2800....

Take that large number and multiply it by the amount of money you originally have, $200. Then you'll get something like 256.0169... Round to the near hundredth, and you'll have 256.02

Answer:

Table price  is Rs 2544

Step-by-step explanation:

Table sold =  Rs 2400

Losses = 6%

Now find  6% of 2400

     ( 2400 × 6 ) ÷ 100 =  144

Add this answer to table price sold

     2400+ 144 = 2544

Answer: 80

Step-by-step explanation:

Angle FGB = 80 degrees b/c supplementary angles.

By the sum of interior angles of a quadrilateral, angle FEB = 360 - 75 - 95 - 90 = 100 degrees.

x is supplementary with this angle and is this 180 - 100 = 80.

Answer:

The factors of a number are all of the numbers that will divide into that number with no remainder. The prime factors of a number are the prime numbers that must be multiplied together to give the number. For example: The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The prime factors of 30 are 2, 3, and 5.

Answer:

Answer:

99.9% sure it's -4, -10, -2

Step-by-step explanation:

y−6≤15+8y

−21≤7y

y≥−3

so that be providing that you're gonna get

-4, -10, -2

Answer:

Slope = -5/8

Step-by-step explanation:

Take 2 points from the graph where the line is. Point 1: (1 , 6). Point 2: (9 , 1).

We are going to use the formula for finding the slope of a line now.

y2 - y1/x2 - x1 = 1 - 6/9 - 1 = -5/8

Slope = -5/8

Answer:

$3

Step-by-step explanation:

Let the cost of an eraser, a pen and a ruler be $e, $p, and $r respectively.

Given:

e +2p +r= 13 -----(1)

2e +p +r= 11 -----(2)

3e= 2r -----(3)

(1) ×3:

3e +6p +3r= 39 ----(4)

Substitute (3) into (4):

2r +6p +3r= 39

6p +5r= 39 -----(5)

(2) ×3:

6e +3p +3r= 33 -----(6)

Substitute (3) into (6):

2(2r) +3p +3r= 33

4r +3p +3r= 33

3p +7r= 33 -----(7)

Let's rewrite equations (5) &(7) so it's easier to compare them:

6p +5r= 39 -----(5)

3p +7r= 33 -----(7)

We can eliminate the term p to find the value of r. This can be done by making sure that the coefficient of p is equal in both equations.

(7) ×2:

6p +14r= 66 -----(8)

(8) -(6):

6p +14r -(6p +5r)= 66 -39

Expand:

6p +14r -6p -5r= 27

9r= 27

r= 27 ÷9

r= 3

Thus, the cost of a ruler is $3.

Answer:

Step-by-step explanation:

7(-4x - 1) = 49

-28x - 7 =49

-28x = 49 + 7 = 56

x = 56/(-28) = -2

Answer:

7 x - 4x = - 28x

7 x - 1 = - 7

-28x - 7 = 49

+7 both sides

-28x = 56

÷ - 28

x = 56/-28

x = - 2

I substitute to double check my answer:

- 4x

-4x-2 =8

7(8- 1)

7x 8 = 56

7 x - 1 = - 7

56-7= 49

Answer:

Step-by-step explanation:

If Δ JKL ~ Δ JHG , then

[tex]\frac{LJ}{GJ}[/tex] = [tex]\frac{KJ}{HJ}[/tex]

[tex]\frac{95}{68}[/tex] ≠ [tex]\frac{87}{72}[/tex] ⇒ triangles are not similar

Answer:

Step-by-step explanation:

It is given

2x−3y=5

we can write it as

3y=2x−5

So we get

y=32x−5​

Substituting x=4 in the given equation

y=32(4)−5​

So we get

Y=38−5​

y=33​

By division we get

y=1

Substituting x=−2 in the given equation

y=32(−2)−5​

So we get

y=3−4−5​

y=3−9​

By division we get

y=−3

x 4       -2

y      1        -3

Now draw a graph using the points (4,1) and (−2,3)

Join the point through a line and find the value of y

(i) Based on the graph

consider x=4 on X-axis

Now the line joining the two points and a point on the Y-axis gives the value of y

Therefore,when x=4 the value of y=1

(ii) Based on the graph,

Consider y=3 on Y-axis

Now the line joining the two points and a point on the X-axis the value of x

Therefore, when y=3 the value of x=7

Answer:

13/25

Step-by-step explanation:

number of black balls = 4

number of white balls = 6

⇒ total number of balls = 10

As the balls are always replaced after being picked:

Therefore,

P(W) and P(W) = 4/10 x 4/10 = 16/100 = 4/25

P(B) and P(B) =  6/10 x 6/10 = 36/100 = 9/25

P(W and W) or P(B and B) = 4/25 + 9/25 = 13/25

Answer:

TRUE

Step-by-step explanation:

Answer:

32 cars

Step-by-step explanation:

If each class has 26 students, we can multiply the number of classes, 6, by the amount of students in each class, to find the total amount of students going on the field trip.

6 * 26 = 156 students

Each vehicle can hold 5 students. To find the amount of vehicles needed to transport all the children, we need to divide the number of students by 5.

156 / 5 = 31.2 vehicles

I don't think they plan on driving 0.2 of a vehicle, so we would have to round. We can't round down because if we did, there would be one student left.

31 * 5 = 155 students

Unless the student plans on biking there, they would have to have 32 cars ready to drive the students to the field trip.
