Work Out The Size Of Angle A

Answers

Answer 1

Answer:

The measure of A is 93

Step-by-step explanation:

Here, we want to get the measure of angle A

we can start by getting the measure of angle C

Mathematically, we can use sine rule

It states that the ratio of the length of a side of a triangle and the sine of the angle it faces is constant

So to get C, we have the following;

9/sin 38 = 11/sin C

sin C = 11sin 38/9

sin C = 0.7525

C = sin^-1(0.7525)

C = 48.80

This is approximately 49

To get A,

we know that if we added the measure of interior angles of a triangle, the addition is 180 degrees

Thus, we have it that:

38 + 49 + A = 180

A = 180-38-49

A = 93

First three terms of a sequence is shown below. Determine if the sequence is geometric. If so, state the common ratio.

30, 10, 103, ...

a.The sequence is geometric, and the common ratio is 13.


b.The sequence is geometric, and the common ratio is 3.


c.The sequence is geometric, and the common ratio is -20.


d.The sequence is not geometric.

Answers

Answer:

Step-by-step explanation:

The common ratio is a constant found by dividing any term by the previous term.

10/30=1/3

103/10=10.3

Since those fractions are not equal this is NOT a geometric sequence.

is -6/3 and integer? dont guess ;( helppp

Answers

Answer:

no because

Fractions and decimals are not integers. All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.

-6/3 is not an integer.

What is Number system?

A number system is defined as a system of writing to express numbers.

We need to check whether -6/3 is a integer or not .

An integer is a whole number (not a fractional number) that can be positive, negative, or zero.

The given number is a fraction which is not comes under the integers.

All whole numbers are integers but  but not all integers are whole numbers or natural numbers.

If the fraction is simplified we get -2 which will be an integer but the fraction form is not considered as integer.

Hence, -6/3 is not an integer.

Find the measure of the given angles. Show work!!

Answers

Answer:

m∠A = 45⁰

m∠B = 75⁰

Step-by-step explanation:

Given question 4;

m∠A = x + 51

m∠B = 81 + x

m∠C = 60⁰

The value of the missing angles can be determined by the finding the value of x first;

m∠A  +  m∠B  + m∠C = 180⁰ (sum of angles in a triangle)

(x + 51)  +  (81 + x)  +  60⁰ = 180

(x + x) + (51 + 81 + 60) = 180

2x + 192 = 180

2x = 180 - 192

2x = -12

x = -12/2

x = -6

Thus, the values of the angles are calculated as follows;

m∠A = x + 51

         = -6 + 51  

          = 45⁰

m∠B = 81 + x

        = 81 - 6

         = 75⁰

the graph of g(x) =x -5 is a translation of the graph of the parent function 5 units

Answers

Answer:

the answer is: 8(x)= 4 -5

Step-by-step explanation:

The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.

The given function is g(x)=x-5.

What is the translation?

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Here, parent function is g(x) = x

To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.

Shifted down: 5 units

The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.

she has to subtract 30 not add 30.

2(3x+6)=3(x-10)

6x + 12 = 3x-30

6x +12 - 12 = 3x - 30 - 12

6x = 3x - 42

6x - 3x = 3x - 42 - 3x

3x = -42

3x/3 = -42/3

x = -14

Answer:

B

Step-by-step explanation:

Hey There!

So the first thing we're going to do is solve it and then compare it to Maya's steps to see where she made the mistake

2(3x+6)=3(x-10)

step 1 distribute the 2 to whats inside of the parenthesis (3x+6)

2*3x=6x

2*6=12

now we have

6x+12=3(x-10)

step 2 distribute 3 to what's inside of the parenthesis

3*x=3x

3*-10=-30

we're left with

6x+12=3x-30

step 3 add 30 to each side

12+30=42

now we have

6x+42=3x

step 4 subtract 6x from each side

3x-6x=-3x

now we have

-3x=42

step 5 divide each side by -3

42/-3=-14

so x = -14

now lets compare our steps to maya's

as we look at the steps we notice that she messes up on step 2

when distributing 3 to -10

she gets positive 30 but its supposed to be -30

so we can conclude that she mad a mistake from step 1 to step 2

therefore the second one is your answer

A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)​

Answers

Answer:

47378.31625 Liters

Step-by-step explanation:

A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)

From the above question,

1 gallon = 3.79 Liters

12500 7/8 gallons = x Liters

Cross Multiply

x Liters = 12500 7/8 × 3.79 Liters

x = 47378.31625 Liters

Therefore, the number of liters of water in the fountain is 47378.31625 Liters

Find the value of x.
A 2
B 4.8
C 6
D 6.4

Answers

Answer:

D

Step-by-step explanation:

Δ DCA and Δ ABE are similar, thus the ratios of corresponding sides are equal, that is

[tex]\frac{CA}{BE}[/tex] = [tex]\frac{DA}{AE}[/tex] , substitute values

[tex]\frac{18}{10}[/tex] = [tex]\frac{x+8}{8}[/tex] ( cross- multiply )

10(x + 8) = 144 ( divide both sides by 10 )

x + 8 = 14.4 ( subtract 8 from both sides )

x = 6.4 → D

The value of x is the length of BD, so x = 6.So, The correct answer is C. 6.

The value of x is the length of the altitude from vertex B to side AC. We can find this length by using the Pythagorean Theorem on right triangle ABD.

[tex]AB^2 + BD^2 = AD^2\\8^2 + BD^2 = 10^2\\BD^2 = 36\\BD = 6[/tex]

The altitude from vertex B to side AC is equal to the length of BD, so x = 6.

Here is a breakdown of the steps involved in solving for x:

We are given the lengths of sides AB and AC of triangle ABC.

We know that the altitude from vertex B to side AC will be perpendicular to side AC. We can use the Pythagorean Theorem on right triangle ABD to find the length of BD, which is the altitude from vertex B to side AC.
