Answer:

80

Step-by-step explanation:

i gotchuuuuu

okok so a really easy way that this can be done is by not doing the full trapezoid, but splitting it up into 2 triangles and 1 rectangle

area of triangle: 1/2BH

area of rectangle: LW

Ookie so first the triangles:

both have the exact same measurements:

7 is the base, and the height is 8. Even tho it doesn't say 8 on one of them, we can visually see that it is the same height.

So, for BOTH triangles, 8*7=56, divided by 2=28.

Now, the rectangle:

width is 3, and length is 8.

8*3=24.

ADD TOGETHER: 28+28+24=80

AREA=80

Answer:

80

Step-by-step explanation:

area of the two triangles

= (7x8)/2x2

= 56

area of the rectangle

= 8x3 = 24

area of the trapezoid

= 56+24

=80

Step-by-step explanation:

For writing the expression, represent 'a number' as x, as it's unknown.

The word format explains;

Four less than x.

Subtracting 4 from x will represent four less than x.

Expression is represented as;

[tex]x - 4[/tex]

Answer:

give the pic..................

Answer:

a = 92° , b = c = 143°

Step-by-step explanation:

a and 88° are same- side interior angles and sum to 180° , that is

a + 88° = 180° ( subtract 88° from both sides )

a = 92°

b and 37° are same- side interior angles and sum to 180° , then

b + 37° = 180° ( subtract 37° from both sides )

b = 143°

b and c are corresponding angles and are congruent , then

c = b = 143°

Answer:

50.24 cm^2

Step-by-step explanation:

The formula for the area of a circle is A = πr^2

The radius is half of the diameter so r = 4

So now you can solve:

A = 3.14(4)^2

= 50.24 cm^2

Answer:

12

Step-by-step explanation:

[tex] \frac{4}{3} = \frac{x}{9} \\ \\ \implies \: 3x = 4 \times 9 \\ \\ \implies \: 3x =36 \\ \\ \implies \: x = \frac{36}{3} \\ \\ \implies \: x =12[/tex]

Answer:

12

Step-by-step explanation:

or;4/3=X/9

or;3x=4×9

or;3x=36

or;X=36/3

Therefore;X=12

The equation ,[tex]-2x^2+5xy-7y^2+9x-7y+13=0[/tex] represents a conic. The discriminant is is -31 , so the represents an ellipse .

A curve obtained by a cone and a plane is called conic .

Here given equation is

[tex]-2x^2+5xy-7y^2+9x-7y+13=0[/tex]

we know that discriminants of equation

[tex]$$A x^{2}+B x y+C y^{2}+D x+E y+F=0$$[/tex]

is [tex]$$D=B^{2}-4 A C$$[/tex]

and if

D<0  it's ellipse

D=0 it's parabola

D>0 It's  hyperbola

Here, the is

[tex]$$D=5^{2}-4(-2)(-7)=-31$$[/tex]

Hence it's an ellipse

Answer: It should be 270 ml

Step-by-step explanation:

To find 3/8 of 720, we need to know 1/8

Divide 720 by 8, this gives you 90

Now multiply 90 by 3 to get 3/8

Answer is 270 ml

Answer:

0.0073

Step-by-step explanation:

<3

Answer:

0.0025

Step-by-step explanation:

This is because , you have the number 75, and dividing that by 3 is 25, but since our number is 0.75, that means we are adding the 2 zeros from our 300 and add it on to be to 0.0025, this won’t work in some situations.

Hope that helps!

Step-by-step explanation:

The left side of the equation HAS TO BE GREATER THAN 3

So we take each ordered pair (x,y), plug it into the expression of left side of inequality and see which one is GREATER THAN 3. That's our answer.

A:

0.5x - 2y

0.5(-2) -2(0.5) = -2

NO

B:

0.5x - 2y

0.5(2) -2(1) = -1

NO

C:

0.5x -2y

0.5(2) -2(-1) = 3

NO

D:

0.5x -2y

0.5(-2) -2(-0.5) = 0

NO

None of them are solutions. C would have been a solution if the inequality had an "EQUAL SIGN" -- but it doesn't. Maybe the question is wrong, but if the question is right, then there is no correct answer.

Condense z₁ and z₂ into their exponential forms:

z₁ = 3 (cos(π/4) + i sin(π/4)) = 3 exp(i π/4)

z₂ = 7 (cos(3π/8) + i sin(3π/8)) = 7 exp(i 3π/8)

Then the quotient of z₁ and z₂ is

z₁ / z₂ = 3/7 exp(i (π/4 - 3π/8)) = 3/7 exp(-i π/8)

and in trigonometric form,

z₁ / z₂ = 3/7 (cos(-π/8) + i sin(-π/8))) … … … D

Answer:

the answer is C.
