I’m so confused can you please help me with this problem. THANK YOU.

Answer:

In a 45 - 45 - 90 triangle, the legs are equal and the ratio of sides from shortest to longest is 1 : 1 : √2 where 1 are the legs and √2 is the hypotenuse. In this case the leg is 10 / √2 = 5√2.

Answer:

Step-by-step explanation:

(1-3)/(5-1)= -2/4 = -1/2

y - 3 = -1/2(x - 1)

y - 3 = -1/2x + 1/2

y - 6/2 = -1/2x + 1/2

y = -1/2x + 7/2

Answer:

Shapes are similar when one can be scaled to be like another one. Circles are always the same shape and they only vary in size. A very small circle can be expanded to be the same size as any other without changing it's shape, only size. However this is not true for ovals since they come in different shapes.

Answer:

They made 36 three-point field goals

Step-by-step explanation:

For free throws , we have one point each.

So here, the total points they made from free throws is 22 * 1 = 22 points

So the number of points made from field goals would be 184-22 = 162 points

So the issue we have now is knowing the number of 3-point field goals that was made.

How can we get this?

Remember they made 85 baskets? so if we subtract the number of free throws, then we can have the number of field throws and that is 85-22 = 63

Now, let the number of 2 points throws be x and the number of 3 points throws be y

From our earlier analysis;

x + y = 63 ••••••••• (i)

Now the total number of three pointers would be 3 * y = 3y and the total number of two pointers would be 2 * x = 2x

Adding both gives a total of 162

Thus;

2x + 3y = 162 •••••••• (ii)

So we have two equations to solve simultaneously.

From equation 1, we can say that;

x = 63-y

Let’s substitute this into equation 2

2(63-y) + 3y = 162

126 -2y + 3y = 162

126+y = 162

y = 162-126

y = 36

This means that they made 36 three-point field goals

Answer:

They made 36 three-point field goals during the game

Answer:

a(n)=60-30n

Step-by-step explanation:

Equation to use:

a(n) = a(1) + d(n-1)

where a(1) is the first term, d is the common difference between terms, and n is the nth term you are trying to find.

In this case, a(1) is 30, d is -30, and n is just n.

If you plug that into the equation and use the distributive property, you would get: a(n) = 30 -30n + 30.

Adding the two 30's gets you: a(n) = 60 - 30n, which is the solution.

Answer:

y = 4x

Step-by-step explanation:

The slope is 4.

The line passes through (0, 0).

Equation of a line y = mx + b, m is the slope, and b is the y-intercept.

y = 4x + b

Put x and y as 0.

0 = 4(0) + b

0 = b

The y-intercept is 0.

The equation of the line is y = 4x.

Step-by-step explanation: Here were given 4 relations in the form of graphs and were asked to determine which one represents a function.

In this situation, we would use what is called the vertical line test.

In other words, if we can draw a vertical line that passes through

more than one point on the graph, then the relation is not a function.

Notice that in this problem, every vertical line draw on a

graph passes through more than 1 point except for W.

So W represents a function.

Answer:

The faucet has turned a total distance of 3 25/28

Step-by-step explanation:

To know the total distance turned by the faucet, what we need to do is to add together the distances to which it has turned.

Mathematically, that would be;

2 1/7 + 1 3/4

which is;

15/7 + 7/4 = (60 + 49)/28 = 109/28 = 3 25/28

Answer:

y<3

Step-by-step explanation:

It is  y<3 because all areas below y=3 are shaded.

In addition, the line y=3 is dotted, which means it is not part of the inequality (i.e. strict inequality).

If it had been a full line, then it would be y<=3.

Answer:

The answer to c is an arc

Answer:

it's an arc of the circle.

Step-by-step explanation:

An arc of a circle is a "portion" of the circumference of the circle.

Answer: Part 1: 111.24

Part 2: 9.27

Part 3: 54 minutes

Step-by-step explanation:

Part 1: Since you already know that the total bill increases by 3%, you just have to find 103% of 180.

1.03*108= 111.24; your answer would be 111.24 pounds

Part 2: Since you already know yearly, 111.24 divided by 12= 9.27 per month

Part 3: First find 73% of 200 which is 146. Then subtract that from 200 which is 54. So you have 54 minutes left.

Answer:

b

Step-by-step explanation:

A line sloping upwards from left to right has a positive gradient.

A line sloping downwards from left to right has a negative slope

If the line crosses the y- axis above the x- axis then y- intercept is positive.

If the line crosses the x- axis below the x- axis then y- intercept is negative.

The line shown slopes downwards from left to right, thus negative gradient

The line crosses the y- axis above the x- axis thus y- intercept is positive

Reorganizando los datos:

15, 16, 17, 18, 19, 19, 24, 25, 26

Mediana de los datos:

(N + 1) / 2

Donde N = número de observaciones

Mediana = (9 +1) / 2 = 10/2 = 5 a observación = 19.

Media = suma de valores observados / número de observaciones

Media = (15 + 16 + 17 + 18 + 19 + 19 + 24 + 25 + 26) / 9

Media = 179/9 = 19.89

B) mediana si se agrega otro niño que pese 43 kg

Los nuevos datos se convierten en:

15, 16, 17, 18, 19, 19, 24, 25, 26, 43

Mediana = (N + 1) / 2

Mediana = (10 + 1) / 2 = 11/2 = 5.5 Como tenemos un decimal:

La mediana será el promedio de la quinta y sexta observación: (19 +19) / 2 = 38/2 = 19

C) No, la media aritmética no parece ser un buen representante de la observación de 10 datos con el valor de peso recién agregado de 43 kg, ya que el valor parece considerablemente más alto que el conjunto de los 9 valores anteriores. Con el peso recién agregado, la media aritmética se convierte en: Media = (15 + 16 + 17 + 18 + 19 + 19 + 24 + 25 + 26 + 43) / 10 Media = 222/10 = 22.2

Answer: 10

Step-by-step explanation:

AB = 2EB

AB=CD

Due to that

Cd = 2EB therefore

CD = 10

The value of CD is 10.

Perpendicular lines are lines that intersect at a right (90 degrees) angle.

Given:

EB= 5

As, OE is perpendicular to AB  

AB = 2EB

Also, AB=CD

so, CD= 2 EB

CD = 2*5

CD= 10

Answer:

The pressure decreased by 18%

Step-by-step explanation:

Given two scenarios:

Step 1: Find the initial pressure

Initial force = 90 Newtons

Initial surface force is applied on = 20 cm²

Initial pressure = initial force/initial surface

*Note: the SI unit for pressure is N/m²

We need to convert cm² to m²

1 cm² = 0.0001 m²

20 cm² = 0.002 m²

Initial pressure = 90/0.002 m²

Initial pressure = 45,000 N/m²

Step 2: find new pressure

New force = 90+5 = 95N

New area = 20+5 = 25 m² = 0.0025m²

New pressure = 95/0.0025 = 38,000

Step 3: find the outcome of the increases by calculating the % change in pressure

% change in pressure = (new pressure - initial pressure)/initial pressure × 100

Thus,

% change in pressure = (38,000 - 45,000)/38,000 × 100

= -7,000/38,000 × 100

= -18.42 ≈ -18%

The outcome of the increase resulted in a decrease in pressure. Thus,

The pressure decreased by 18%

Answer:

The pressure is decreased by 15.56%

Answer:

x = 21

Step-by-step explanation:

(x-6) /3 = 5

Multiply each side by 3

(x-6) /3 * 3 = 5*3

x-6 = 15

Add 6 to each side

x-6+6 = 15+6

x = 21

The supplementary angles are:

<1 and <3

<1 and <4

<2 and <3

Angles that add up to 180 degrees are referred to as supplementary angles. For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°. The sum of complimentary angles is 90 degrees.
