Hi Can You See If This Question Answer A And B Correct Or Not

Answers

Answer 1

Answer :

a=93

b=19

Step-by-step explanation:

For (a)

Triangle total angles = 180

So we have

40+57+x = 180

x= 180 - 97

x= 83

Now,

x+ a =180( straight Angel)

83+a = 180

a = 93

Or,

You can use exterior angle theorem:

The exterior angle of a triangle is equal to the sum of the two opposite interior angles

a = 40+57

= 93

For (b)

Using the exterior angle theorem

b+38 =57

b = 57 - 38

= 19

Answer 2

Answer:

The correct answer is a= 97°

b=19°

Dyscalculia is a learning disorder that affects a person’s ability to do the math.

A learning problem called dyscalculia diminishes a person's capacity for math. Similar to how dyslexia impairs reading-related brain regions, dyscalculia interferes with the knowledge and skills connected to math and numbers. Although dyscalculia often first manifests in childhood, it can even affect adults who are unaware of it.

The signs of this condition typically emerge in childhood, particularly as kids start to master the fundamentals of math. However, many adults who suffer from dyscalculia are unaware of it. When forced to do the math, people with dyscalculia frequently experience mental health problems like anxiety, depression, and other distressing emotions.

7/6  -  5/12, -3/4 - 2/3.

What is Algebraic expression ?

Algebraic expression can be defined as the combination of variables and constants.

Given ,

So given expressions are,

13/24  +  7/12   =  13+ 7*2 / 24  = 13+14 / 24 = 27/24

7/6  -  5/12 = 7*2 - 5 / 12  = 14-5/12 = 9/12

-3/4 - 2/3 = - (3/4 + 2/3 ) = - ( 9 + 8 / 12) = -17/12

5 - 7/10  = 5*10 - 7 / 10  =  50 - 7 / 10 = 43/10

1/8  -  5/3   = 3 - 8*5 / 24  = 3-40 / 24 = -37 / 24

3/2 -  4/5 = 3*5 - 2*4 / 10  = 15-8 / 10  = 7/10

Therefore, The expressions which are having common denominator 24 are 13/24  +  7/12 , 1/8  -  5/3 and for 10 are 5 - 7/10 , 3/2 -  4/5 and for 12 are 7/6  -  5/12, -3/4 - 2/3.

Express the following as a rate.
a) 20 litres of Petrol for R180​

Answers

The rate of petrol in this case is R9 per liter.

What is rate?

In mathematics, rate is a measure of how one quantity changes in relation to another quantity. It is often expressed as a ratio or fraction, where the numerator represents the amount of change in the first quantity and the denominator represents the amount of change in the second quantity.

The rate of petrol can be expressed as the cost per liter. To find the cost per liter of petrol in this case, we can divide the total cost by the total amount of petrol:

Cost per liter = Total cost / Total amount

For the given scenario, we have 20 litres of petrol for R180. So the rate can be calculated as:

Rate = Total cost / Total amount = R180 / 20 litres

Simplifying the expression, we get:

Rate = R9 per litre

Therefore, the rate of petrol in this case is R9 per liter.

A men's health magazine would like to conduct a survey using a simple random sample of 900 men who practice yoga. One of the goals of the survey is to create a confidence interval to estimate the proportion of all men practicing yoga who report low stress levels. Since the intended survey method requires face-to-face interaction, some of the magazine executives are concerned about the cost of the survey and suggest sampling a smaller group of 100 men instead of 900 men. Assuming the sample proportion doesn't change, which of the following best describes the anticipated effect on the width of the confidence interval if the magazine were to survey a random sample of 100 men who practice yoga, rather than 900 men? A) The width of the interval based on 100 men would be about nine times the width of the interval based on 900 men.
B) The width of the interval based on 100 men would be about three times the width of the interval based on 900 men. C) The width of the interval based on 100 men would be about the same width as the interval based on 900 men. D) The width of the interval based on 100 men would be about one-third the width of the interval based on 900 men. E)
The width of the interval based on 100 men would be about one-ninth the width of the interval based on 900 men.

Answers

The width of the interval based on 100 men would be about three times the width of the interval based on 900 men.

What is the width of the interval?

The width of a confidence interval for a proportion is proportional to the standard error of the sample proportion, which is proportional to the square root of the sample size.

The standard error is defined as the standard deviation of the sampling distribution of the sample proportion, which is estimated by the standard deviation of the Bernoulli distribution (square root of the sample proportion times (1 - sample proportion) divided by the sample size).

So, if the sample size is reduced by a factor of 9 (from 900 to 100), the standard error (and hence the width of the confidence interval) would increase by a factor of 3 (square root of 9).

Therefore, The width of the interval based on 100 men would be about three times the width of the interval based on 900 men.

The number of center of rotations to produce the image is (d) infinite

How to determine the number of centers?

An arrow pointing to the left is symmetric around its central axis.

This means that any point along the central axis of the arrow can serve as a center of rotation to produce an image of a left-pointing arrow.

The central axis is a straight line that runs through the middle of the arrow from the tip to the base, and also extend through the arrow's depth.

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

According to question:

We need to find angle 1 and 2

So, by using corresponding angle theorem,

∠1 = 135°

Answers

Answer:

no solutions

Step-by-step explanation:

8(2w - 3) = 4(4w - 8)

Use distributive property.

16w - 24 = 16w - 32

subtract 16w from both sides.

-24 = -32

When the variable falls out of the equation as you are working on it, and you're left with a false statement, there is no solution.

Answer:

no solution

Step-by-step explanation:

to find the value of w, we have to isolate it on one side of the equation.

first, we distribute the numbers outside of the parentheses and multiply them to each term on the inside. this gives us:

16w - 24 = 16w - 32

next, we move 24 to the other side of the equation by adding 24 to both sides. by doing this, we get rid of 24 on the left side by making its value 0, and we add it to -32 on the right side. this gives us:

16w = 16w - 8

after this, we do the same with the 16w on the right side and subtract it from both sides. however, you might notice that there's a problem here.

when you try to move the 16w on the right side to the left side, you subtract 16w from itself, which gets rid of the variable entirely. whenever this happens, there are no values of the variable that make the equation possible- meaning that the answer is no solution.

if jenna saves $2500 per year with an intrest of 10% compounded annually how much would she have in 30 years

Answers

Answer: Jenna would have $37,175 in 30 years if she saves $2500 per year with an interest rate of 10% compounded annually.

Step-by-step explanation:

To calculate the total amount Jenna would have after 30 years of saving $2500 per year with an interest rate of 10% compounded annually, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the final amount (principal + interest)

P = the initial principal (the amount Jenna saves each year, $2500 in this case)

r = the interest rate (10% in this case, so 0.10)

n = the number of times interest is compounded per year (annually in this case, so 1)

t = the number of years (30 in this case)

Plugging in the values:

A = $2500(1 + 0.10/1)^(1*30) = $2500(1.10)^30 = $2500(14.87) = $37,175

So, Jenna would have $37,175 in 30 years if she saves $2500 per year with an interest rate of 10% compounded annually.

The measure of angle m∠CBD is equal to 55°

How to to evaluate for the missing angle m∠CBD

We shall first find the measure of the angle m∠CDB so that we can evaluate for the measure of angle m∠CBD using the sum of interior angles of a triangle theorem as follows:

m∠ADB and m∠CDB are on a straight line and their sum is equal to 180° so;

m∠CBD + 80° = 180° {sum of angles on a straight line}

m∠CDB = 180° - 80° {subtract 80° from both sides}

m∠CDB = 100°

m∠BCD + m∠CDB + m∠CBD = 180° {sum of interior angles of a triangle}

25° + 100° + m∠CBD = 180°

125° + m∠CBD = 180°

m∠CBD = 180° - 125° {subtract 125° from both sides}

m∠CBD = 55°

In conclusion, the measure of angle m∠CBD is equal to 55°.
