Answer:

x=130°

y=50°

z=130°

Step-by-step explanation:

__________

Answer:

x = 130°

y = 50°

z = 130°

Step-by-step explanation:

From the diagram, you can see that the angle given, 50° is a vertical angle to y. This means they are equal, so y = 50°.

Next, angle x, and the given 50° angle are supplementary since they form a straight line. Because of this, you get that:

50° + x = 180°

- and -

x = 130°

You can see that angle z is a vertical angle to angle x, so they are equal, which gives you z = x = 130°. --> z = 130°

Answer:

d:e is 2:3

Step-by-step explanation:

if 'e' is 150% more than 'd' we can say that 'e' is 1.5 and 'd' is 1

ratio of 1/1.5 or 1÷3/2 is 2/3

Answer:

B. A linear function with a positive slope.

Step-by-step explanation:

A correlation can be defined as a numerical measure of the relationship existing between two variables (x and y).

In Mathematics and Statistics, a group of data can either be negatively correlated, positively correlated or not correlated at all.

1. For a negative correlation: a set of values in a data increases, when the other set begins to decrease. Here, the correlation coefficient is less than zero (0).

2. For a positive correlation: a set of values in a data increases, when the other set also increases. Here, the correlation coefficient is greater than zero (0).

3. For no or zero correlation: a set of values in a data has no effect on the other set. Here, the correlation coefficient is equal to zero (0).

A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional. Thus, the graph of a linear function is a straight-line and it has a positive slope which is always constant.

From the graph, we can deduce that the scatter points lie close to a straight line with a slope that is positive.

Hence, the type of function which best models the relationship between the sales of sweaters and gloves is a linear function.

Mathematically, slope is given by the formula;

[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]

[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Answer:

12

Step-by-step explanation:

divide into two shapes. the first one being 2 x 4 units and the second being 2 x 2.

2 x 4 = 8

2 x 2 = 4

8 + 4 = 12

The answer is 12 square units.

Answer: circle

Step-by-step explanation:

The shape of the cross-section is formed when a cylinder intersects the plane is a circle option (A) is correct.

In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.

We know the volume of the cylinder is given by:

[tex]\rm V = \pi r^2 h[/tex]

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

As we know, the circle is a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

As we can see in the picture the cylinder is cut by a plane that is parallel to the base of the cylinder.

The base of the cylinder is a circle.

the shape of the cross-section is formed when a cylinder intersects a

the plane is a circle.

Thus, the shape of the cross-section is formed when a cylinder intersects the plane is a circle option (A) is correct.

Answer:

y = 15

Step-by-step explanation:

Given :

3, 2, y, 10

If the numbers are in proportion :

We can thus say :

3/2 = y/10

Cross multiply

3 * 10 = 2 * y

30 = 2y

Divide both sides by 2

30 / 2 = 2y / 2

15 = y

Answer: 2/3

Step-by-step explanation:

The probability that the next chew Damian removes from the bag will be cherry or peach as a fraction in simplest form is 55/576

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability for the strawberry chews:

P(strawberry chews) = 16/48

Probability for the cherry chews:

P(cherry chews) = 10/48

Probability for the peach chews:

P(peach chews) = 22/48

Now the probability of cherry or peach = P(cherry)×P(peach)

[tex]=\frac{10}{48} \times\frac{22}{48}[/tex]

= 220/2304

= 55/576

Thus, the probability that the next chew Damian removes from the bag will be cherry or peach as a fraction in simplest form is 55/576

Answer:

D

Step-by-step explanation:

By looking at the terms, we can notice that each term is 4 times the previous term. This means the series is geometric and we can rule out options A and B because of this. We can find the first terms of both options C and D to get:

first term c: 4

first term d: 1

The first term of our series is one, so that must mean D is the answer.
