Option C

Step-by-step explanation:

The y values are 2.5 times the x value. Only graph 3 shows the correct numbers.

Hope it helps!

Answer:

y=-2/8x+5

Step-by-step explanation:

Answer:

[tex]y=-(1/2) x X-1= - x/2-1[/tex]

Step-by-step explanation:

Answer:

x=1/2, y=4

Step-by-step explanation:

Double both sides of the top equation:

4x+6y=26

Now subtract boths sides of the second one from the first one:

(4x+6y) - (4x-y) = 26 - (-2)

7y = 28

so y = 4

4x-y=-2 so 4x-4=-2

4x=2

x=1/2

Answer:

68°

Step-by-step explanation:

since the angle given is a complementary angle, we know that the sum of it must equal 180°

let the unknown angle below j be x so,

[tex]25+43+x=180\\x=180-25-43\\x=112[/tex]

now since the angle on the left of j is equal to x we can say

[tex]x+j=180\\j=180-x\\j=180-112\\j=68[/tex]

Answer:

13.7ft^2

Step-by-step explanation:

Area for triangle:

The formula for the area of a triangle in this scenario is area=(b*h)/2

The base length is 3.6ft and the height is 4.8ft. We can now substitute these values into the equation. So:

area=(3.6*4.8)/2

area=8.64ft^2 for the triangle

Area for semi-circle:

The formula for the area of a circle is area=pi*r^2. To find the area of the semi-circle, we can half the area of the circle at the end.

The question says to use 3.14 for the value of pi.

The diameter is given as 3.6ft, so to find the radius, we simply divide the diameter by 2; so 3.6/2=1.8ft for the radius

Now, we can just substitute these values into the equation above. So:

area=3.14*(1.8)^2

area=3.14*3.24

area=10.1736ft^2 (DO NOT ROUND THIS ANSWER!!).

However, this area is for the COMPLETE circle. We want the area for the semicircle shown above. Therefore, divide the circle area by 2. So:

10.1736/2=5.0868ft^2 for the semicircle.

Total area of shape

Now we have the area of the two separate shapes, we can simply add them together. So:

8.64ft^2 + 5.0868ft^2 = 13.7268ft^2 altogether (unrounded)

Now, finally we must round to 1/10, or to 1 decimal place. Therefore, the final value for the area would be 13.7ft^2.

Hope this helped!!

Answer:

60.4 degrees

Step-by-step explanation:

Complementary angles are 2 angles that add up to the sum of 90 degrees.

90-29.6=60.4 degrees

B

Step-by-step explanation:

Soemthing is a function if it can pass the vertical line test

the vertical line test is when you draw a vertical line and it only touches the graph once

Another way of thinking about this is no function can have two of the same values on the x axis

I'm not too sure what's happening with the third response but the answer is B

Answer:

  4.3 in

Step-by-step explanation:

The Law of Cosines is applicable when you have two sides and the angle between them. The third side satisfies ...

  f² = d² + e² -2de·cos(F)

  f² = 6.4² + 7.8² -2·6.4·7.8·cos(33°) ≈ 18.0671

  f ≈ √18.0671 ≈ 4.2505

The length of f is about 4.3 inches.

Answer:

11

Step-by-step explanation:

15-4 = x

15-4 = 11

x = 11

to isolate x, you move 4 to the other side and it becomes 15-4 = x

Answer:

C

Step-by-step explanation:

Answer:

q = 9

Step-by-step explanation:

we can see it is a parallelogram so opposite sides are equal.

q - 3 = 6 ( being opposite sides of parallelogram)

q = 6 + 3

q = 9

Answer:

[tex]10cm^2[/tex]

Step-by-step explanation:

We are given that

Two parallel sides of trapezoid are

[tex]a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm[/tex]

[tex]b=3\frac{1}{2}=3+0.5=3.5 cm[/tex]

Height of trapezoid, h=4 cm

We have to find the area of the trapezoid.

We know that

Area of trapezoid=[tex]\frac{1}{2}(a+b)h[/tex]

Where a and b are two parallel sides

h=Height of trapezoid

Using the formula

Area of trapezoid=[tex]\frac{1}{2}(1.5+3.5)\times 2[/tex]

Area of trapezoid=[tex]10cm^2[/tex]

Step-by-step explanation:

A pentagon's angle all add up to 540

[tex]460+x=540[/tex]

[tex]x=80[/tex]

Answer:A 80

Step-by-step explanation:

So a square is all 90° angles so take 90 from 140 and get 50 and 50+50=100 and a triangles thing adds up to 180 so 180-100=80 (I’m not good at explaining sorry)

Answer is 60 times.

Explanation:

Prime numbers in a die are 2, 3 and 5 (i.e. 3 numbers)

Total outcomes can be 1, 2, 3, 4, 5 and 6 (i.e. 6 numbers)

Probability

= Number of preferred outcomes/ Total number of outcomes

= 3/6

= 1/2

= 0.5

Probability of getting a prime number while throwing the dice 120 times

= 0.5 × 120

= 60 times
