Anyone knows how to do "Using Congruence Postulates," I need help with an equation, can someone show me step by step.

Answer:

False

Step-by-step explanation:

False

There is not enough information to guarantee the lines are perpendicular.

No, we can not say that AB and CD are perpendicular from the information given.

Two geometric objects are perpendicular if their intersection forms right angles at the point of intersection called a foot.

The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂.

Given that a triangle ABC, divided into two triangles by a line DC, also

angle DAC and DBC are congruent,

From the given information we can not conclude any relation between both triangles,

Hence, we can not say that AB ⊥ CD

Answer:

-177.8 feet below sea level.

Step-by-step explanation:

First, we know that decend means to lower. Anything lower than 0 has to be negative. It says that she decends for 91 seconds at a speed of 2.2 feet per second. So first to find out how many feet she descended in those 91 seconds, you need to multiply 91*-2.2= -200.2. Then, it says that she ascends for 32 seconds at the speed of 0.7 feet per second. It's the same thing, but ascend means to go up. So, we multiply 32*0.7=22.4. Now we add the two numbers together to get -177.8.

Step-by-step explanation:

Después de una pequeña búsqueda online, encuentre las tablas para este problema, las cuales se pueden observar abajo.

La moda es el valor que más se repite, para el caso de Pablo, podemos ver que el valor 14 se repite dos veces (de hecho es el único que se repite). Entonces es el valor que más se repite. Entonces la moda de Pablo es 14.

Para el caso de Claudio podemos ver que ningún valor se repite, entonces los datos de Claudio no tienen una moda.

Answer:

the gas cost for the entire trip is $77

Step-by-step explanation:

Given that

For the first 300 miles, it spend $12.50 on gas

We need to find out the gas cost for the overall trip at the time when it drives 960 miles

So, it should be

= 960 miles ÷ $12.50

= $76.80

= $77

Hence, the gas cost for the entire trip is $77

Step-by-step explanation:

they gave us 53 and there is the 90 degree angle so you just add that and find the missing since itll equal 180

Answer:

the second option

yes, because they are similar triangles

Step-by-step explanation:

the scaling factor is 3

3×3 = 9

3×7 = 21

so, the ratios of the sides remain the same, and the 90 degree angle remains the same. therefore, just one triangle is larger than the other, but the relative attributes and even the orientation are the same, so yes, since we don't know the absolute coordinates of the corners, indeed, the Hypotenuse of both triangles could be on the same line.

Answer:

Volume of cone = 33.49 inch³

Step-by-step explanation:

Missing information;

Height of cone = 8 inch

Diameter of cone = 4 inch

Find:

Volume of cone

Computation:

Radius of cone = Diameter of cone / 2

Radius of cone = 4 / 2

Radius of cone = 2 inch

Volume of cone = [1/3][πr²h]

Volume of cone = [1/3][(3.14)(2)²8]

Volume of cone = [1/3][(3.14)(4)8]

Volume of cone = [1/3][(3.14)(32)]

Volume of cone = [1/3][100.48]

Volume of cone = 33.49 inch³

Answer:

11 and 33

Step-by-step explanation:

The greater of two numbers is 3 times the smaller.

Let the numbers be

n and 3n

sum is 44

n + 3n = 44

4n = 44

Divide both sides by 4

n = 11

3n = 3 * 11

3n = 33

Answer:

smaller number is 11

bigger number is 33.

Step-by-step explanation:

Lets make the smaller number be a, the bigger number 3a since its 3 times a's value

the sum of a and 3a is 44

so we write

a+3a = 44

combine like terms

a+3a = 4a

4a = 44

divide both sides by 4

a = 11.

Now we know the smaller number is equal to 11, but we are not done just yet.

We have to find the value of the bigger number by plugging in 11 into our equation

11+3*11 = 44

11 + 33 = 44

which means the bigger number is 33

Answer:

The car price decreased by $2,268.

The price of the car now is $33,732.

Step-by-step explanation:

Multiply 0.063 (6.3% in decimal form) by $36,000 to get $2,268, which is how much the price decreased.

Then subtract 2,268 from 36,000 to get $33,73, which is the price of the car after the decrease.

Answer:

Step-by-step explanation:

6.3 : 100 = x : 36000

x = (36000 * 6.3)/100 = $2268 (decrease in price)

Price of new model: 36000 - 2268 = $33732

Given:

Rahul and Swapnil brought an equal amount of money for shopping.

Rahul spend rupees 95 and Swapnil spend rupees 350.

After that Swapnil had [tex]\dfrac{4}{7}[/tex] of what Rahul had left.

To find:

How much money did Rahul have left after shopping.

Solution:

Let x be the amount brought by both Rahul and Swapnil.

Rahul spend rupees 95 and Swapnil spend rupees 350. So, the remaining amounts are:

Rahul's remaining amount = [tex]x-95[/tex]

Swapnil's remaining amount = [tex]x-350[/tex]

After that Swapnil had [tex]\dfrac{4}{7}[/tex] of what Rahul had left.

[tex](x-350)=\dfrac{4}{7}\times (x-95)[/tex]

[tex]7(x-350)=4(x-95)[/tex]

[tex]7x-2450=4x-380[/tex]

Isolate the variable terms.

[tex]7x-4x=2450-380[/tex]

[tex]3x=2070[/tex]

[tex]x=\dfrac{2070}{3}[/tex]

[tex]x=690[/tex]

Now, the remaining amount of Rahul is:

[tex]x-95=690-95[/tex]

[tex]x-95=595[/tex]

Area = Length x width

Area of carpet = 6 x 6 = 36 square meters

Cost of carpet per square meter = total cost / area

Cost per square meter: 390 / 36 = £10.83

Area of room = 5 x 5 = 25 square meters.

Area of rug not used = area of room subtracted from area of carpet:

36 - 25 = 11 square meters

Cost of the carpet not used = area of carpet not used x cost per square meter

11 x 10.83 = 119.13

ANSWER: £119.13

Answer:

Area = Length x width

Area of carpet = 6 x 6 = 36 square meters

Cost of carpet per square meter = total cost / area

Cost per square meter: 390 / 36 = £10.83

Area of room = 5 x 5 = 25 square meters.

Area of rug not used = area of room subtracted from area of carpet:

36 - 25 = 11 square meters

Cost of the carpet not used = area of carpet not used x cost per square meter

11 x 10.83 = 119.13

Answer:

Step-by-step explanation:

Use the formula of distance between two points (x₁, y₁) and (x₂, y₂),

Distance =  [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

1). Distance between (4, 1) and (2, 2) = [tex]\sqrt{(4-2)^2+(1-2)^2}[/tex]

                                                        = [tex]\sqrt{5}[/tex]

                                                        = 2.24

2). Distance between (-5, 2) and (-3, -2) = [tex]\sqrt{(-5+3)^2+(2+2)^2}[/tex]

                                                            = [tex]\sqrt{20}[/tex]

                                                            = 4.47

3). Distance between (3, -4) and (-2, 1) = [tex]\sqrt{(3+2)^2+(-4-1)^2}[/tex]

                                                          = [tex]\sqrt{50}[/tex]

                                                          = 7.07

4). Distance between (-1, -2) and (1, -4) = [tex]\sqrt{(1+1)^2+(-4+2)^2}[/tex]

                                                          = [tex]\sqrt{8}[/tex]

                                                          = 2.83

5). Distance between (5, -2) and (-1, -1) = [tex]\sqrt{(5+1)^2+(-2+1)^2}[/tex]

                                                           = [tex]\sqrt{37}[/tex]

                                                           = 6.08

Therefore, increasing order of the distance will be 2.24 > 2.83 > 4.47 > 6.08 > 7.07

                                                       =

                                                       = 2.24

2). Distance between (-5, 2) and (-3, -2) =

                                                           =

                                                           = 4.47

3). Distance between (3, -4) and (-2, 1) =

                                                         =

                                                         = 7.07

4). Distance between (-1, -2) and (1, -4) =

                                                         =

                                                         = 2.83

5). Distance between (5, -2) and (-1, -1) =

                                                          =

                                                          = 6.08

Therefore, increasing order of the distance will be 2.24 > 2.83 > 4.47 > 6.08 > 7.07

Answer:

No, ice cream cannot fits inside the cone.

Step-by-step explanation:

radius of cone, r = 3 cm

height of cone, h = 10 cm

radius of ice cream sphere, R = 33.5 cm

The volume of the cone is

[tex]V =\frac {1}{3}\times \pi\times r^{2}\times h\\\\V = \frac{1}{3}\times 3.14\times 3\times 3\times 10\\\\V =94.2cc[/tex]

Volume of ice cream

[tex]V' =\frac{4}{3}\pi\times r^{3}\\\\V'= \frac{4}{3}\times 3.14\times 3.5^{3}\\\\V' = 179.5cc[/tex]

As the volume of ice cream is more than the volume of cone, so it cannot fit into the cone.
