What is the area of the kite? 20 points.

The equation would be x² + x = 42 which represents "the sum of a number and its square is 42". The correct answer would be an option (A).

Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.

We have been given that the sum of a number and its square is 42.

Let's assume the required number would be x

According to the given question, translate the phrase into an algebraic form:

The number = x

The number's square = x²

Thus, the sum of a number and its square is 42 will be as:

⇒ number + number's square = 42

⇒ x +  x² = 42

Therefore, the equation would be x² + x = 42 which represents "the sum of a number and its square is 42".

Hence, the correct answer would be option (A).

Answer:The answers are in the step by steps.

Step-by-step explanation:

A.   outcomes           GREEN           BLUE

    probabilities           0.72                0.28  

B.  0.72 *  75 =54   meaning Yosef will draw a green marble 54 times if he draws a total of 75 marbles.

I believe that is 12

Very sorry if I am wrong

Step-by-step explanation:

This problem is very easy if you think about it!

12 to the left if negetive to if you move to the left your subtracting.

If your moving at a speed of [tex]5/6[/tex] per minute where will you be in 10.2

minutes?

EASY

[tex]5/6[/tex] × 10.2=8.5

Now all we need to do is subtract 8.5 from 12.

12-8.5= 3.5

Therefor the answer is...

Step-by-step explanation:

make it into two linear equations y=.19x and y=29.95+.08x

Answer:

[tex]n[/tex].

Step-by-step explanation:

Assuming that [tex]n \in Z^{+}[/tex], then all number less than [tex]n+1[/tex] are

[tex]n+1-1=n[/tex]

Notice that the "plus one" indicates that the whole number shown by the expression [tex]n+1[/tex] indicates a whole number greater than [tex]n\\[/tex] by one unit. So, we just subtract one whole unit to achive a number less than the given expression.

Therefore, the answer is [tex]n[/tex].

Answer:

x=9.5

Step-by-step explanation:

In order to find the answer, we know that 6x + 4x - 5 = 90

Next we want to combine like terms: 10x - 5 = 90.

Now we have to add 5 to 90 in order to get x on its own.  10x = 95

Now solve for x by dividing 95 by 10: x=9.5

Answer:

y=-2x-2

Step-by-step explanation:

Slope: -4-2/1-(-2)=-6/3=-2

Equation: y=-2x+b

Substitute: 2=-2(-2)+b

2=4+b

b=-2

Therefore, y=-2x-2

I hope this helped and have a good rest of your day!

Answer:y =-2x-2

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

The largest angle will be the angle that is opposite to longest side.

Longest side is AB = 18 cm. So, opposite angle of side AB is ∠C

Sides from largest to smallest : AB   >   AC   > BC

angles form largest to smallest: ∠C  >  ∠B   >   ∠A

Answer:

x = 7°

<GDH = 112°

<FDH = 192°

<FDE = 135°

Step-by-step explanation:

If DE bisects <GDH this means that <GDE = <EDH

Given <GDE = (8x+1)° and <EDH = (6x+15)° then;

8x+1 = 6x+15

8x-6x = 15-1

2x = 14

x = 7°

Since <GDH = <GDE + <EDH

<GDH = 8x-1+6x+15

<GDH = 14x+14

<GDH = 14(7)+14

<GDH = 98+14

<GDH = 112°

For <FDH,

Note that sum of angle on a straight line is 180°

<FDH = <FDG + <GDE + <EDH

<FDH = <FDG + <GDH

<FDG = 180-(43+8x+1)

<FDG = 180-44-8x = 136-8x

<FDH = 136-8x+112

<FDH = 248-8x

<FDH = 248-8(7)

<FDH = 248-56

<FDH = 192°

For <FDE;

<FDE = <FDG + <GDE

<FDE = 136-8x+8x-1

<FDE = 135°

Answer:

30 ft

Step-by-step explanation:

[tex]3 \frac{3}{4} = \frac{15}{4} \\15*2=30[/tex]

Answer:

30 feet

Step-by-step explanation:

If each 1/4 in is equal to 2 feet, then you can find out how many in per feet, by dividing 2 by 1/4, to get 8. You can then multiply 8 by 3 3/4 to get the amount of feet that the living room is if it measures 3 3/4 in on the floor plan.

V=one third (3)(3)(5)

Step-by-step explanation:

the guy above has good reviews lol

Answer:

The answer is 20%.

Step-by-step explanation:

10/50= 10 divided by 50=.2

.2 times 100 (because percentages are out of 100) = 20

20% is your answer

For A:

You add the probabilities to get the answer to A: = .75, or 3/4

Note that the probability of ALL THREE of them hitting would be 1/3 x 1/4 x 1/5.

For B:

2/3 and 3/4 is the probability of the other two people MISSING (the remainder of 1/3, 1/4)

1.0 = 100% chance to hit the target, so 1.0 x 2/3 x 3/4 = 1/2

Mark's chance of hitting is 1/5, so do 1/2 x 1/5, = 1/10

Answer:

Answer:

187 cm^2

Step-by-step explanation:

Area of a parallelogram is base times height. 17 cm is the base and 11 cm is the height so, 17 cm times 11 cm equals 187 cm^2.

Answer:

[tex]\frac{79}{12}[/tex] or 6[tex]\frac{7}{12}[/tex] gallons of gas.

Step-by-step explanation:

First, you have to convert both of your mixed numbers into a improper fractions.

2 [tex]\frac{1}{4}[/tex] = 9/4

4 [tex]\frac{2}{6}[/tex]   = 26/6

Second, find the greatest common multiple of the denominators of both. In this case, it would be 12.

Then find the number that the first improper fraction's denominator would be multiplied by to get the GCM.  Multiply both the nominator and the denominator by that number.

4 would need to be multiplied by 3 to get 12. So we multiply 9/4 by 3/3. We would get 27/12.

Repeat that for the second fraction's denominator.

6 would need to be multiplied by 2 to get 12. So we multiply 26/6 by 2/2. We would get 52/12.

Then add both fractions together.

[tex]\frac{27}{12}+\frac{52}{12}[/tex] [tex]=\frac{79}{12}[/tex]

If you need to, simplify.

[tex]\frac{79}{12} = 6\frac{7}{12}[/tex]

Hope that helped!

Answer:

could u provide a proper picture to this question?

Step-by-step explanation:

Answer: y= -0.5+8

Step-by-step explanation:

Any line that is perpendicular to a line is the opposite and inverse.

Ex. for a line to be perpendicular to 2, the reverse would be -2 and the opposite is -1/2.

Now we need to focus on the b in y=mx+b.

To do that, we plug in 4 as y and -2 in x to find b.

4=2(-2)+b

4=-4+b

And we find that b is 8.

So in conclusion, y=-0.5+8

Right triangle, Pythagorean Theorem:

c² = a² + b²

a=8, b=9

c² = 8² + 9²  = 64 + 81 = 145

c = √145 inches

That's the exact answer but they want us to ruin it with an approximation.

c ≈ 12.041594578792296 inches
