WHAT IS THE ANSWER TO THIS AND WHY THANK YOU!


[tex](−1+√5) \div 2[/tex]
​

Answer:

55

Step-by-step explanation:

Put the one shape and split it into two other shapes. A square and a triangle.

find the areas of both of the shapes and add them together.

5×5=25

5×12=60/2 = 30

25+30=55

Answer:

55 units²

Step-by-step explanation:

The area of this shape would be the area of a square with sides 5 and a triangle with a base of 5 and a height of 12

To find the area of this shape, add the area's of the two shapes

This would be written as:

[tex]5^{2} +\frac{5*12}{2} \\ =25+(5*6)\\ =25+30\\= 55[/tex]

Answer:

Ha recorrido 8 km.

Step-by-step explanation:

Primero debes multiplicar el diámetro de la rueda por el número de vueltas que ha dado para encontrar cuánto ha recorrido:

80cm*10.000=80.000 cm

Ahora, debes convertir los 800.000 cm a km usando una regla de tres considerando que 1 km es igual a 100.000 cm:

1 km    →    100.000 cm

 x       ←    800.000 cm

x=(800.000*1)/100.000

x=8 km

De acuerdo a esto, la respuesta es que ha recorrido 8 km.

Answer: [tex]t<444.44[/tex]

Step-by-step explanation:

Given

Texting bill is given by [tex]c(t)=0.09t[/tex]

Spending must be less than [tex]\$40\ \text{per month}[/tex]

So, text billing must be less than $40

[tex]\therefore 0.09t<40\\\\\Rightarrow t<\dfrac{40}{0.09}\\\\\Rightarrow t<444.44[/tex]

Answer:

P(blue)=1/2 50 marbles are blue

Answer:

x = 10.

Step-by-step explanation:

From the definition of the mean:

(4 + 3 + 3 + x) / 4 = 5

4 + 3 + 3 + x = 20

x + 10 = 20

x = 10.

Answer:

65°

Step-by-step explanation:

x + 85° = 150°

x = ( 150 - 85 )°

x = 65°

Answer:

your answer is 65°

I don't know if they want it rounded or not, but rounded it would be 529.88 or 529.9

Step-by-step explanation:

Find the volume of the can (cylinder):

h = 12 cm

d = 7.5 cm

r = 1/2d = 3.75 cm

[tex]V=\pi r^2h\\\\= (3.14)(3.75)^2(12)\\\\= 529.875[/tex]

Answer:

C

Step-by-step explanation:

We can cross A and B off cause it involves multiplication

We can cross D off cause 3 + 3 + 3 = 9, not 27

Answer:

68 games

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Games won = 85%

Game lost = 12

Here, 100% - 85% = 12

15% = 12

or 1% = 0.8

So, total games played (100%) = 80 games

Now, number of games won = Total games - Games lost

= 80 - 12

= 68 games

Hence, Kelly's team wins 68 games in the season.

It's D. the median for town A, 30, is less than the median for town B, 40.

The median for town A at 30° is less than the median for town B at 40°.

So, option (D) is the correct answer.

The median is the "middle" of a sorted list of numbers. To find the median, place the numbers in value order and find the middle number".

For the given diagram,

Town A has temperatures = 20°, 30°, 40°

Town B has temperatures = 30°, 40°, 50°

The median of A = 30°

The median of B = 40°

Hence, From the above values, the median for town A at 30° is less than the median for town B at 40°.

Hence, we can conclude that option (D) is the correct answer.

Answer:

78 ft squared

Step-by-step explanation:

To find the area of trapezoid, we could use this formula:

.5*height*(sum of bases)

We know both the base lengths. They are 10 and 16 ft.

The height can be found by looking at that right triangle whose base is (16-10) ft or 6 ft.

So we want to find the height which is opposite the 45 degree angle and we have the adjacent side's measurement of 6ft.

This has the tangent ratio written all over it since tangent of an angle is opposite side's measurement over adjacent side's measurement.

tan(45)=height/6

1=height/6

6=height

6ft=height

The answer is:

.5*height*(sum of bases)

.5*6 ft*(10 ft+16 ft)

3 ft(26 ft)

78 ft squared

Note: That one right triangle is an isosceles right triangle so we didn't need trigonometry.

Answer:

Brandon's methot is not correct

for example: x=9 9×1/2=4.5

Here's why:

Let's use his method to find the square root of 36. That means we multiply 36 by 1/2 = 0.5 to get 36*0.5 = 18; however, 18 is not the square root of 36. We can see that 18*18 = 324. Instead, the square root of 36 is 6 because 6*6 = 36.

As another example, let's say we want to find the square root of 64. With Brandon's method, we would get to 64*0.5 = 32, but 32*32 = 1024. Ashley's method is correct and 8*8 = 64 shows that 8 is the square root of 64.

As a visual approach, think of a square with side lengths 8 feet each. The area would be 8*8 = 64 square feet. If you didn't know the side length, but you knew that the area was 64 square feet, then you could apply the square root operation to find the side length to be 8 feet (or you could effectively use Ashley's guess-and-check method to arrive at 8 feet). In short, the square root operation is the opposite of squaring a number. We consider these inverse operations.

Multiplying by 1/2 is the same as dividing by 2. Division is the opposite of multiplication, and division is not the inverse of squaring a number. It's just a coincidence that Brandon's method happened to work on the value 4. But as shown earlier, it doesn't work in general.

Answer:

The quadratic equation is;

y = 3x^2-7x + 5

when x = 4, y = 25

Step-by-step explanation:

Mathematically, the general form of a quadratic equation is;

y = ax^2 + bx + c

From the first point, we have that x = 0

Thus;

5 = a(0)^2 + b(0) +c

c = 5

Now, in a case when x is 2

3 = a(2)^2 + b(2) + 5

3 = 4a + 2b + 5

4a + 2b = -2 ••••••(i)

when x = 6

71 = a(6)^2 + b(6) + 5

66 = 36a + 6b ••••••(ii)

From equation i,

2b = -2-4a ••••(iii)

we can rewrite equation ii as

66 = 36a + 3(2b)

Substitute iii into ii

66 = 36a + 3(-2-4a)

66 = 36a - 6 - 12a

66 + 6 = 36a -12a

24a = 72

a = 72/24

a = 3

Recall;

2b = -2-4a

2b = -2-4(3)

2b = -2-12

2b = -14

b = -14/2

b = -7

So the quadratic equation would be;

y = 3x^2 -7x + 5

Now let us test;

when x = 10, y = 235

That would be:

y = 3(10)^2 -7(10) + 5

y = 300 - 70 + 5

y = 235

This shows that the derived quadratic equation is correct

Now, when x = 4; we have it that;

y = 3(4)^2 -7(4) + 5

y = 48 -28 + 5

y = 20 + 5 = 25

C) 15% off with a $15 rebate

Step-by-step explanation:

So a rebate is like a refund which means:

A) 120(.8) = 96         You use .8 because you’re paying 80%

B) 120-30= 90

C) 120(.85) = 102     you use .85 because you’re paying 85%, now

 102-15= 87         Subtract 15 since you get a $15 rebate

D) 120(.9)=108   You use .9 since you are paying 90%

    108-20= 88    Subtract 20 since you get a $20 rebate

since C ended up with the lowest price, the answer is C

Answer:

The angle marked E is 120 degrees

Step-by-step explanation:

Here, we want to get the value of the angle marked E

when two triangles are similar/congruent, we have equal angle measures

Using the markings, we can deduce the following relationships;

4y -28 = 83 + y

4y-y = 83 + 28

3y = 111

y = 111/3

y = 37

So, we have;

4y-28 as

4(37) - 28

= 120

Answer:

Hexagon

Step-by-step explanation:

It has more than 3 sides because it is more sides than a triangle and less than 5 since it has to be fewer sides than a pentagon. A hexagon has 6 sides meaning it has more sides than the pentagon.

Answer:

It should be hexagon

Step-by-step explanation:

Hex equals 6 and quad equals 4, so it would not be quadrilateral or square or recanatgle. So hexagon is your answer.
