Two sides of a triangle have lengths 4 and 8. Which of the following can NOT be the length of the third side? A. 5 B. 6 C. 4 D. 7

Answer:

where is the diagram please put it

Answer:

[tex]hypotenuse = 5 \: cm \\ height = 5 - 1 = 4 \: cm \\ base = \sqrt{ {5}^{2} - {4}^{2} } = \sqrt{9} = 3 \: cm[/tex]

Part A:

[tex]perimeter = 5 + 4 + 3 \\ = 12 \: cm[/tex]

Part B:

[tex]area = \frac{1}{2} \times base \times height \\ = \frac{1}{2} \times 3 \times 4 \\ = 6 \: {cm}^{2} [/tex]

Answer:

72 pints of the first type

18 pints of the second type

Step-by-step explanation:

See attachment for complete question

Given

[tex]x \to[/tex] first type

[tex]y \to[/tex] second type

Final volume = 90; So:

[tex]x + y = 90[/tex]

From the question, we understand that:

70% of x and 95% of y gives 75% of the fruit juice

This is represented as:

[tex]70\% * x + 95\% * y = 75\%* 90[/tex]

Make x the subject in [tex]x + y = 90[/tex]

[tex]x = 90 - y[/tex]

Substitute: [tex]x = 90 - y[/tex] in [tex]70\% * x + 95\% * y = 75\% * 90[/tex]

[tex]70\% * (90 - y) + 95\% * y = 75\% *90[/tex]

Express percentage as decimal

[tex]0.70 * (90 - y) + 0.95 * y = 0.75 * 90[/tex]

Open brackets

[tex]63 - 0.70y + 0.95y = 67.5[/tex]

Collect like terms

[tex]- 0.70y + 0.95y = 67.5 - 63[/tex]

[tex]0.25y = 4.5[/tex]

Divide both sides by 0.25

[tex]y = \frac{4.5}{0.25}[/tex]

[tex]y = 18[/tex]

Recall that: [tex]x = 90 - y[/tex]

[tex]x = 90 - 18[/tex]

[tex]x = 72[/tex]

Answer:

Step-by-step explanation:

take the -4 then times it by 2 and you will get -8

Answer:

Step-by-step explanation:

We have to use Pythagorean's Theorem twice here, first to find the length of the dotted line, which I will call h, and then again to find x. First we need to find h so we can use it to find x:

[tex](2\sqrt{5})^2=4^2+h^2[/tex] and

[tex]20=16+h^2[/tex] and

[tex]4=h^2[/tex] so

h = 2. Then again:

[tex]x^2=2^2+22^2[/tex] and

[tex]x^2=4+484[/tex] and

[tex]x^2=488[/tex] so

x = 2√122

Answer:

Area =  [tex]44yd^2[/tex]

Step-by-step explanation:

a = 7 , b = 4 , h = 8

[tex]Area = \frac{a + b}{2 } \times height = \frac{7+4}{2} \times 8 = \frac{11}{2} \times 8 = 11 \times 4 = 44yd^2[/tex]

Answer:17

Step-by-step explanation:

Cm+cq=mq (m nằm giữa c và q)

f + 6 = ?

Well, the answer can be pretty much any number. It all depends on what number f is. f is a variable, so you can plug in any number to replace f.

For example, if f was 5, this is what the equation would look like:

5 + 6 = 11

If f was -3, this is what the equation would look like:

-3 + 6 = 3

So, again, the answer can be anything. It depends on what f is.

Answer:

x = 6/k

Step-by-step explanation:

kx + 12 = 3*kx

to make like terms on same side shift kx to right hand side . when u shift positive kx to other side it becomes negative

12 = 3kx - kx

12 = 2kx

shift 2 to left hand side when u shift multilication changes to division.

12/2 = kx

6 = kx

to find x u must shift k to other side . here also same since k and x are multilied when k shifts to others side it becomes divisor.

6/k = x

Answer:

x = -4

Step-by-step explanation:

The axis of symmetry is the vertical line that makes a mirror image on the left and right for a vertical parabola

It goes through the vertex and is the x coordinate

x = -4

Answer:

Perimeter you add up all the sides.  If it is a horizontal or vertical line, you just write those values for the side lengths.  For the slanted one, I would use pythagorean theorem to solve it.

Step-by-step explanation:

If we make a right triangle using vertical and horizontal lines. We will find that a = 6, and b = 12.  Find the square root of the sum of a squared plus b squared.  That will tell you C.  Then add C to the other 3 sides and that will give you the perimeter.

Answer:

Step-by-step explanation:

take 30 degree as reference angle

using sin rule

sin 30=opposite/hypotenuse

1/2=x/10(do cross multiplication)

2*x=10*1

x=10/2

x=5

Answer:

5

Step-by-step explanation:

The sin is the opposite cathetus divided by the hypothenuse, and the sin30° = 0.5, so let's do an equality:

sin30° = x/10

0.5 = x/10

10•0.5 = x

x = 5

f(3) = 13

Answer:

128degrees

Step-by-step explanation:

Using the theorem that states that the angle at the centre is twice the angle at the circumference, hence;

<D = 180 - 116

<D = 64

<x = 2(<D)

<x = 2(64)

<x = 128

Hence the measure of <x is 128degrees

Answer:

5088 is the perimeter of the rectangle.

Answer:

5088 is the right answer

The formula of perimeter of rectangule is 2(l+b)

So, l=1472 b=1072

2(1472+1072)

2(2544)

2×2544 IS 5088

Answer:

x = 64 degree  , 2x = 128 degree

Step-by-step explanation:

2x = 128 (being alternate interior angles)

x = 128/2

x = 64 degree

2x

=2*64

=128 degree

The value of angle 2x is 128 and angle x is 64.

Lines on a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other.

When two lines in a plane are stretched endlessly in both directions and do not cross, they are said to be parallel. If two straight lines have separate y-intercepts and equal slopes, they are said to be parallel. A few significant parallel line attributes that accurately describe their features are shown below.

given:

<1 = 2x

<2 = 128

now, using alternate interior angle

< 1 = <2

2x = 128

x= 128/2

x= 64

Hence, the value of 2x is 128 and x is 64.

Answer:

y-3 = (1/4)x; 4y = -4x +14; y=4

Step-by-step explanation:

>First find the equation of function A

general equation of a line is y=mx+b

m = (y2-y1)/(x2-x1)= (0-(7/2))/(-7-0) = (-7/2) *(1/-7)  = 1/2

consider the point (-7,0)

0 = -7(1/2) +b

7/2 = b

Function A has the equation y= (1/2)x +7/2

>rewrite the equations to fit the standard form

y-3 = (1/4)x ; add 3 to both sides

y= (1/4) x +3

4y = -4x +14 ,divide by 4 both sides

y= -x + 7/2

y=4

> intercept less than A

y-intercept for function A , y= (1/2)x +7/2, is  7/2 =3.5

y-intercept for function y= (1/4) x +3 is 3

3  < 7/2, so the answer is y-3 = (1/4)x

> intercept equal to A

y-intercept for function A , y= (1/2)x +7/2, is  7/2

y-intercept for function y= -x + 7/2 is 7/2

7/2=7/2 , so the answer is 4y = -4x +14

> intercept greater than A

y-intercept for function A , y= (1/2)x +7/2, is  7/2 =3.5

y-intercept for function y=4 is 4

4 > 7/2
