Answer:

x is 24 degrees

Answer:

x = 24

Step-by-step explanation:

I'm 8 years old and I know how to do this.

The sum of interior angles of a quadrilateral is 360°

The sum of a supplementary angle is 180°

180 - 111 = 69

94 + 41 + 69 + a = 360

204 + a = 360

a = 156

156 + x = 180

x = 24

Answer:

17 cm

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 +b^2 = c^2  where a and b are the legs and c is the hypotenuse

8^2 + 15^2 =c^2

64+225 = c^2

289 = c^2

Take the square root of each side

sqrt(289) = sqrt(c^2)

17 = c

Answer:

The hypotenuse is 17cm

Step-by-step explanation:

Pythagoras theorem is :   [tex]a^{2} +b^{2} =c^{2}[/tex]

To work out the hypotenuse of this triangle you would first need to know Pythagoras theorem. The theorem states that [tex]a^{2} +b^{2} =c^{2}[/tex]. A and B are the 2 lengths given in this question and c is the hypotenuse.

The first step in working out the hypotenuse is to square the base of 8, this gives you 64.

Then you would need to square the height of 15, this gives you 225. This is because we are substituting the values into a and b.

Then the next step is to add the values of 64 and 225, this gives you 289.

The final step is to root the value of 289, which gives you 17cm. This is because as c is the hypotenuse while the value worked out is c squared and so to work out c you would have to root it.

1) Square the base of 8cm.

[tex]8^{2} =64[/tex]

2) Square the height of 15cm.

[tex]15^{2} =225[/tex]

3) Add 64 and 225.

[tex]64+225=289[/tex]

4) Root the value of 289.

[tex]\sqrt{289}= 17cm[/tex]

Answer:

(-1,2)

Step-by-step explanation:

Found answer on brainly.

Answer:

(-1,2)

Step-by-step explanation:

In this problem, the signs are switched because there is a rule to 180 rotation that is (x,y) to (-x,-y).

(1,-2)×(-1x, -1y)= (-1,2) .

if both points were negative, the points would be positive. if they were positive, they would be negative.

Answer:

[tex]y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]

Step-by-step explanation:

We begin with the differential equation [tex]\frac{dy}{dx} =(1-x)(1-y)[/tex]

Firstly, we need to get the [tex]y[/tex] and [tex]dy[/tex] as well as the [tex]x[/tex] and [tex]dx[/tex] on the same sides as each other

To do this, we can multiply each side by [tex]dx[/tex] and divide each side by [tex](1-y)[/tex]

Doing this will give us the following differential

[tex]\frac{1}{1-y} dy=(1-x)dx[/tex]

Now, we can integrate each side

[tex]\int\limits\frac{1}{1-y} \, dy =\int (1-x) \, dx\\\\-ln(1-y)=x-x^2+c_{1}[/tex]

Now, we need to solve for y

[tex]-ln(1-y)=x-x^2+c_{1}\\\\ln(1-y)=x^2-x+c_{2} \\\\1-y=e^{x^2-x+c_{2}} \\\\y=1-e^{x^2-x+c_{2}}\\\\y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]

Question:

The parallelogram shown below has an area of 40 units squared.

Find the missing base.

Answer:

See Explanation Below

Step-by-step explanation:

The question is incomplete as the diagram which shows the dimension of the parallelogram is not attached.

However, I'll give a general explanation on how to get the base of the parallelogram. If you follow this explanation, you'll get the right answer regarding your question.

The area of a parallelogram is calculated as thus.

Area = Base * Height

Given that the area = 40 units²

Let's assume the height of the parallelogram is 10 unit.

All you need to do is to plug in these values in the formula above..

Area = Base * Height becomes

40 = Base * 10

Divide both sides by 10

40/10 = Base * 10/10

4 = Base

Hence, Base = 4 units

Or take for instance the height is 5 units.

You'll still follow the simple steps as it is above.

Area = Base * Height becomes

40 = Base * 5

Divide both sides by 5

40/5 = Base * 5/5

8 = Base

Hence, Base = 8 units

Answer:

49 cm²

Step-by-step explanation:

The area for a square is Area = length x width, and if the square name tag is 7cm long on "each side", that means that both the length and the width are 7cm.

Plug this into the formula to get A = 7cm x 7cm.

This can be simplified to A = 49cm².

Answer: 49 cm^2

Step-by-step explanation:

7 x 7 = 49

Answer:

D) 9 m2

Step-by-step explanation:

a rectangular prism has six rectangular faces or sides, its surface area is just the sum of the six faces, you can calculate the surface area with the formula 2 length  width + 2 * width * height + 2 * height * length, where length, width and height.

B. 6m^2

Step-by-step explanation:

I just found the area of the faces and chose the one that was an answer choice

Answer:

5/12 - 4/5 = -23/60. You can't simplify -23/60. Hope this is right

Step-by-step explanation:

4/5= 48/60

5/12 =  25/60

25/60-48/60= -23/60

Answer: 32 steaks

Step-by-step explanation:

Given data:

Each steak surface requirement = 0.25 square feet of the grill.

Maximum number of steaks mike can grill at

2.5 feet

2 feet and

3.5 feet

Solution.

At 2.5 feet

= 2.5 / 0.25

= 10 steaks

At 2 feet

= 2 / 0.25

= 8 steaks

At 3.5 feet

= 3.5 / 0.25

= 14 steaks

Total number of steaks

= 10 + 8 + 14

= 32 steaks

Answer:

Step-by-step explanation:

I believe is D because you actually change the measure of two angles as long as the sum of them are 90.

Answer:

Step-by-step explanation:

We cannot factor this function out which tells us that there are no zeros. The graph backs this up because we can see that there are none. The easiest way to graph this would start by plugging in points and making a table for yourself.

Lets start by plugging in -1.

(-1)^2-2(-1)+3 =6, this means we have a point at (-1,6).

Now lets plug in 0.

(0)^2-2(0)+3= 3 (0,3)

For plugging in 1

(1)^2-2(1)+3=2 (1,2) (this happens to be the vertex)

And lastly lets plug in 2

(2)^2-2(2)+3=3 (2,3)

Depending on how many points are needed, keep plugging in numbers like we did above.

Answer:

85°

Step-by-step explanation:

We need to use the angle fact that angles in a quadrilateral add up to 360° and that a right angle is 90°, using this information we can for an equation to find the value of 1. Lets call "1" x so we don't confuse it with an angle. So,

x + 85 + 100 + 90 = 360

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 90 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

x + 85 + 100 + 90 = 360

→ Simplify equation

x + 275 = 360

→ Minus 275 from both sides to isolate x

x = 85

The measure of angle '1' is 85°

Answer:

85°

Step-by-step explanation:

∠1+85°+100°+90°= 360°

∠1 = 360°- 275°= 85°

∠1 =85°

Answer:

x=20

60÷3=20

Answer:

x = 20

3x = 60

x = 60 : 3

x = 20

Answer:

2:4  means one part is 2/(2+4)=1/3 of AB and the other part is 2/3 of AB

Step-by-step explanation:

Add  1/3 of the distance from -2 to 4.  (1/3)(4+2)=2.  -2+2=0   The x coordinate is 0

Subtract 1/3 of the distance from 6 to -6,  (1/3)6+6)=4   6-4=2  The y coordinate is 2

The point is (0,2)

Check the answer

distance from (-2,6) to (0,2)   is square root of (-2)^2 + (4)^2 = sqr20 = 2(5)^2

distance from (0,2) to (4,-6)  is square root of (4)^2 +(8)^2 = sqr80 = 4(5)^2

First distance is half the 2nd distance,  so the point divides AB into 2 parts in a ratio of 2:4

Answer:

The Pythagorean theorem works only on right triangles. Also it is used to find the hypotenuse when you know 2 other sides.

Step-by-step explanation:

Answer: The Pythagorean Theorem is a formula used to find the hypotenuse (the value of C2).

Step-by-step explanation: That formula is A2 + B2 = C2. Right Triangles are the only triangles that relate to the Pythagorean Theorem.
