Can someone find the area

Answers

Lets split this into two parts; a semi circle and triangle. We can solve fro the area of both individually first.

Area of the Semi Circle:

Formula: A = (πr²)/2

The radius is the diameter divided by two (16 / 2 = 8)

A = (π*8²)/2

A = (π64)/2

A = 200.96/2

A = 100.48 meters

The area of the semi circle is 100.48 meters

Area of the Triangle:

Formula: A = bh/2

A = 16*12/2

A = 192/2

A = 96 meters

The area of the triangle is 96 meters.

To find the total area of the shape, we can add.

100.48 + 96 = 196.48 meters.

To solve the trigonometric inequality sin?(x) -0.85, Carl graphed the equations y=sin(x) and y=-0.85. Shelly, on the other
hand, took the cube root of both sides of the inequality so that it became sin(x) = -0.85, and she then graphed the equations
y = sin(x) and y -0.85. Which of the following statements is true regarding the points of intersection of Carl's graph and
Shelly's graph?

A The points of intersection of Carl's graph have different x-coordinates than the points of intersection of Shelly's graph and
different y-coordinates.

B The points of intersection of Carl's graph have different x-coordinates than the points of intersection of Shelly's graph but the
same y-coordinates.

C The points of intersection of Carl's graph have the same x-coordinates as the points of intersection of Shelly's graph but
different y-coordinates.

D The points of intersection of Carl's graph have the same x-coordinates as the points of intersection of Shelly's graph and the
same y-coordinates.

Answers

Answer: C

Step-by-step explanation:

The points of intersection of Carl’s graph have the same x-coordinates as the points of intersection of Shelly’s graph but different y-coordinates.

Trigonometric expressions can be represented using inequalities

The true statement is (c) the points of intersection of Carl’s graph have the same x-coordinates as the points of intersection of Shelly’s graph but different y-coordinates.

The inequality is given as:

[tex]\mathbf{sin^3(x) < -0.85}[/tex]

The steps Carl took will give the following coordinates (x, y^3)

The steps Shelly took will give the following coordinates (x, y)

This means that, their results will have the same x-coordinates but different y-coordinates.

Hence, the true option is (c)

Answer:

x = 34t

408

Step-by-step explanation:

x = 34t

x: no. of copies

t: minutes

x = 34(12)

x = 408

Answer:

= 12

x = total number of copies

total number of copies

copies per minute

= number of minutes copier runs

B ) x / 34 = 12 is correct

Given ΔSTU and ΔDEF, what is m∠U ?

Answers

Answer:

In this context:

[tex]\boxed{m\angle U=40^{\circ}}[/tex]

Explanation:

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any diagram, so I'll assume ΔSTU and ΔDEF are similar. Two triangles are similar if and only if their corresponding angles are congruent and their corresponding sides are in proportion.

So:

[tex]\angle S=\angle D \ldots eq1 \\ \\ \angle T=\angle E \ldots eq2 \\ \\ \angle U=\angle F \ldots eq3[/tex]

We also know:

[tex]\angle S+\angle T+\angle U=180^{\circ} \ldots eq4 \\ \\ \angle D+\angle E+\angle F=180^{\circ} \ldots eq5[/tex]

Suppose we know:

[tex]\angle S=30^{\circ} \\ \\ \angle E=110^{\circ}[/tex]

Then, by eq2:

[tex]\angle T=\angle E =110^{\circ}[/tex]

By substituting ∠S and ∠T into eq4:

[tex]\angle S+\angle T+\angle U=180^{\circ} \\ \\ 30^{\circ}+110^{\circ}+\angle U=180^{\circ} \\ \\ \\ Isolating \ \angle U: \\ \\ \angle U=180^{\circ}-(30^{\circ}+110^{\circ}) \\ \\ \angle U=180^{\circ}-140^{\circ} \\ \\ \angle U=40^{\circ}[/tex]

Finally:

[tex]\boxed{m\angle U=40^{\circ}}[/tex]

can a triangle have to acute angles and one obtuse angle

Answers

Answer:

yes

Step-by-step explanation:

Any obtuse triangle will also have two acute angles.

The sum of angles in a triangle is 180°. If one of the angles is 90° or more (a right or obtuse angle), the other two (non-zero) angles must be less than 90°.

An obtuse triangle is one that has an obtuse angle, so both of the remaining angles must be less than 90°, that is, they must be acute angles.

Answer:

Yes

Step-by-step explanation:

Example:

A triangle with angles: 100°, 50°, 30°

What is the length of the paintbrush in centimeters?
A.0.101 cm
B.10,100 cm
C.1,010 cm
D.10.1 cm

Answers

Answer:

Step-by-step explanation:

The length of the paintbrush in centimeters is D. 10.1 cm.

What is Unit Conversion?

Unit conversion is defined as expressing the same quantity by different measurement units.

For example, a distance of 20 meter can be also expressed as 2000 cm. The distance is same.

Given that,

Length of the paintbrush in millimeters = 101 millimeters

We have to find the length of the same paintbrush in centimeters.

We have the unit conversion,

1 centimeter = 10 millimeters

So,

1 millimeter = 1/10 = 0.1 centimeters

So, we have to multiply the measurement in millimeter with 0.1.

101 millimeters = 101 × 0.1 = 10.1 centimeters

Hence the length is 10.1 centimeters

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting at least 1 red?

Answers

Answer:

1/7

Step-by-step explanation:

i learned this arealdy

The probability of drawing at least one red marble from a bag containing 3 blue and 5 red marbles in two draws without replacement is 19/28.

To find the probability of drawing at least one red marble from a bag with 3 blue and 5 red marbles, with one draw already taken, we calculate the probability of not drawing a red marble and subtract that from 1. Since there are more red than blue marbles, the probability of drawing a red one on the first draw is higher. However, the problem states that the marbles are not replaced after drawing, so the probabilities change with every draw.

There are two ways to not draw a red marble in two draws:

First draw: blue, Second draw: blue.

First draw: red, Second draw: blue.

Let's calculate these probabilities. For the first case, there's a 3/8 chance of drawing blue first, and then 2/7 chance of drawing blue again, since one blue marble has been removed, which equals to 3/8 * 2/7 = 6/56 or 3/28. For the second case, there is a 5/8 chance of drawing red first, and then a 3/7 chance of drawing blue, equalling 5/8 * 3/7 = 15/56. The sum of these probabilities is 3/28 + 15/56 = 9/28.

Therefore, to find the probability of at least one red, we subtract the summed probabilities from 1: 1 - 9/28 = 19/28.

Thus, the probability of drawing at least one red marble is 19/28.

Jim’s family is choosing whether to go to a restaurant for lunch or for dinner. The cost of a salad is $7 at lunch and $9 at dinner. The cost of a steak is $10 at lunch and $12 at dinner.

How many people will choose a salad?

Answers

Answer:

To answer the problem above we let x be the number of people who prefers salad and y be the number of people who chose steak. For lunch they will be spending $41. That is,

7x + 10y = 41

Now, for dinner they will be spending $51. That is,

9x + 12y = 51

The values of x and y from both equations are 3 and 2, respectively. Therefore, 3 people will choose a salad

What is the difference between joint, marginal, and conditional relative frequencies?

Answers

Answer:

The middle cells are the joint frequency numbers. When analyzing data in a two-way frequency table, you will be looking for joint relative frequency, which is the ratio of the frequency in a particular category and the total number of data values. The purple cells on this table are all joint frequency numbers.

The numbers in the column on the very right and on the row on the very bottom are the marginal frequency numbers. When analyzing data in a two-way frequency table, you will be looking for marginal relative frequency, which is the ratio of the sum of the joint relative frequency in a row or column and the total number of data values.

Conditional relative frequency numbers are the ratio of a joint relative frequency and related marginal relative frequency.

Answers

Answer:

x+20

Step-by-step explanation:

As we can see n the diagram, there are parallel traversals and one line, and the two angles given are same-side interior angles. We know that when there is parallel traversal, and we have same side interiors, the sum of the measure of the two angles are supplementary. Supplementary means 180 degrees, or a straight line.

So we plug everything in and we have 4x+5x=180 degrees

4x+5x=9x, so 9x=180

We divide by 9 on both sides to get the value of x, which is 20
