Answer:

110 degrees

Step-by-step explanation:

ABL + ABC = 180

BED + ABC = 180 ( BED = ABL )

BED = 180 - ABC = 180 - 70 = 110

Answer:

B

Step-by-step explanation:

Answer: We can find the equation of a plane in point-normal form, which is given by:

Ax + By + Cz + D = 0

where (A, B, C) is the normal vector to the plane and (x, y, z) are the coordinates of any point on the plane, and D is a constant.

To find the normal vector, we can use the cross product of two vectors that lie on the plane. A convenient choice for these vectors is the direction vector of the line, which is given by:

v = <2-3, -1-4, 5-(-1)> = < -1, -5, 6 >

The normal vector to the plane is given by the cross product of the direction vector of the line and the vector pointing from any point on the line to the point (2,-3,1). Let's call this vector v2 = <2-3, -3-4, 1-(-1)> = < -1, -7, 2>

So the normal vector is given by:

n = v x v2 = ( -52 + 6-7)i + (6*-1 - -12)j + (-1-7 - -5*2)k = (14)i + (-7)j + (-11)k

Given that the point (2,-3,1) lies on the plane, we can substitute these values in the point-normal form equation:

A2 + B-3 + C*1 + D = 0

-142 + -7-3 + -11*1 + D = 0

-28 - 21 - 11 + D = 0

D = 58

So the equation of the plane is :

14x - 7y - 11z + 58 = 0

This is the equation that represents the plane that passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5)

Answer:

c. 2/13

Step-by-step explanation:

The bag starts with 8 red marbles, 4 green marbles, and 2 yellow marbles. Since he draws a red marble from the bag and does not replace it, there will be one less marble.

So now there are 7 red marbles, 4 green marbles, and 2 yellow marbles. Add the number of marbles together and then find the probability of drawing a yellow marble.

7+4+2 = 13

2/13

So the probability of Bill drawing a yellow marble would be 2/13.

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Answer:

Since the sum of the angles of a triangle equal 180 degrees.

2x+5x+15+4x=180

11x+15=180

11x=165

x=15

ABC=2x=2(15)=30 degrees

BCA=4x=4(15)=60 degrees

CAB=5x+15=5(15)+15=90 degrees

Answer: 1/3x + 1/2

Step-by-step explanation: combine like terms. 1/3x + 2/3x - 2/3x = 1/3x

3/4 - 1/4 = 1/2

Therefore, the answer is 1/3x + 1/2

This question is based on the simple calculation. Therefore, the expression is equivalent to

\(\dfrac{1}{3}x +\dfrac{3}{4} +\dfrac{2}{3} x - \dfrac{1}{4} - \dfrac{2}{3}x\)  is   \(\dfrac{1}{3} x+\dfrac{1}{2}\)  .

Given:

\(\dfrac{1}{3} x+\dfrac{3}{4} +\dfrac{2}{3} x - \dfrac{1}{4} - \dfrac{2}{3}x\)

We need to determined an expression that is equivalent to\(\dfrac{1}{3}x +\dfrac{3}{4} +\dfrac{2}{3} x - \dfrac{1}{4} - \dfrac{2}{3}x\)

Now, solve it further as follows:

Separate the like terms , we get,

\(\dfrac{1}{3}x +\dfrac{2}{3} x-\dfrac{2}{3} x+\dfrac{3}{4} - \dfrac{1}{4}\)

Thus, further calculated  we get,

\(\Rightarrow \dfrac{1}{3} x+\dfrac{1}{2}\)

Therefore, the expression is equivalent to

\(\dfrac{1}{3}x +\dfrac{3}{4} +\dfrac{2}{3} x - \dfrac{1}{4} - \dfrac{2}{3}x\)  is   \(\dfrac{1}{3} x+\dfrac{1}{2}\)  .

Answer:

20

Step-by-step explanation:

The first step is to find out the similarity reason of the sides of the triangle, so we just divide the big side by the small side (12/4=3).

Now, for the similarity reason of the areas, we just square that number (3^2=9).

Then we just divide the area of the big triangle by 9, which is 180/9= 20.

Two figures are known as similar figures if there the corresponding angles are equal and the corresponding sider is in ratio. The area of the △DEF is 20cm².

Two figures are known as similar figures if there the corresponding angles are equal and the corresponding sider is in ratio. It is denoted by the symbol "~".

Given △ABC∼△DEF, therefore, the sides will be in a particular ratio,

Ratio = AB/DE = 12/4 = 3

Also, the area of △ABC is 180 square centimeters. since the area is a two-dimensional quantity it will be the product of two sides, therefore, the ratio will also be multiplied twice. Thus, the area of △DEF will be 1/9 of the area of △ABC. Hence, the area of △DEF is,

△DEF = △ABC/9

△DEF = 180cm²/9 = 20cm²

Hence, the area of the △DEF is 20cm².

Answer:

1.75a - 11

Step-by-step explanation:

Remember your order of operations, first you want to start inside the parantheses. Nothing can be simplified there so move on to multiplication.

Distribute (mutiply) ¾ with (5a - 16) as well as -⅓ with (6a - 3) to get

3.75a - 12 - 2a + 1

Combine like terms, so 3.75 with -2a as well as -12 with 1.

1.75a - 11

⁷⁄₄a - 11 or 1¾a - 11

Answer:

The amount invested at 9% is $30,000

Step-by-step explanation:

Mardi received an inheritance of $40,000.

Let x be the amount invested at 9%.

So, Amount invested at 10% = 40000-x

Her total annual income from the investments was  $3700.

So, \(0.09x+0.1(40000-x)=3700\)

\(0.09x+4000-0.1x=3700\)

x=30000

Hence the amount invested at 9% is $30,000

Answer and explanation:

First, the domain is all real numbers except 0, since x = 0 is the asymptote.

D: x ∊ R, x ≠ 0

or

D: (-∞, 0) ∪ (0, ∞)

The range is everything below y = 0.

R: y < 0

or

R: (0, -∞)

Next, this function is never constant so there are only intervals of increasing and decreasing. The intervals meet at x = 0.

inc: x > 0

dec: x < 9

inc: (0, ∞)

dec: (0, -∞)

Answer:

50/3

Step-by-step explanation:

area of triangle = 10

area of circle = 10

area of triangle + area of circle = 20

The white sector of the circle has central angle 60°.

Its area is 1/6 the area of the circle.

To find the gray area, you must subtract the white area from the area of the circle and also subtract the white area from the area of the triangle. Two times the white area is 1/3 the area of the circle.

gray area = 20 - (1/3)10

gray area = 20 - 10/3

gray area = 60/3 - 10/3

gray area = 50/3

Answer:

The white sector of the circle = (1/6) (10) = 10/6 = 5/3

So....the grey area = 10 + 10 - 2 (5/3) = 20 - 10/3 = 60/3 - 10/3 = 50 / 3
