Answer:

x<85

Step-by-step explanation:

first we change the sentence in formula as the following

2x‒58<112

then we can solve easly

2x<112+58

2x<170

2x/2<170/2

x<85

x=-1

y=10/3

Step-by-step explanation:

You can solve the system of equations by applying the elimination method as following:

- Add both equations, then:

- Finally, you must substitute the value of x obtained into one the original equations and then you must solve fot y:

Answer:

x = 145 degrees

Step-by-step explanation:

In leftmost triangle, missing angle :

= 180 - (90 + 35)

= 55 degrees

Top angle of middle triangle :

= 180 - (60 + 55)

= 180 - 115

= 65 degrees

Bottom angle of middle triangle :

= 180 - (90 + 65)

= 25 degrees

Linear pair

= 180 - 25

=> x = 145 degrees

Answer:

9 students in music class.

Step-by-step explanation:

In art there are 4 and since there are 8 more 8 + 4 = 12. so there are 12 in Art.

4 x _ = 12. —> 4 x 3 = 12.
so we need to do the same for music class.

For music there are 3.
so we multiply by 3 like we did with the 4.

3 x 3 = _ —> 3 x 3 =9.
so there are 9 students in music class.

You can't repeat coords on the x or y coordinate, meaning that the one to the left is wrong because it is the only one that repeats

Answer:

First table

Step-by-step explanation:

How do you figure out if a relation is a function? You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain(x) is matched with exactly one element in the range(y). If so, you have a function!

Let's try it on the first table; Lucky us! we found it! the value 1 and 2 repeat more than once connecting with with two DIFFERENT y values!

Answer:

180°

Step-by-step explanation:

The given information are;

The of the object = 180°

Therefore, a line drawn though the a point on the preimage passing through the center of rotation

A second line is drawn from the center of rotation, towards the direction of the expected location of the image of the chosen point on the preimage which should in this case be 180° and the distance from the location of the point on the image to the given center of rotation should be the same as the distance of the point of the preimage from the given center of rotation.

Answer:

Factored form: (x+4)(x+5) = 0

x = -5 or -4

Step-by-step explanation:

To factor x^2 + 9x + 20, we need to find 2 numbers that multiply to 20 and add up to 9.

The reason for that is because when you multiply (x+a)(x+b) using FOIL, you will get x^2 + ax + bx + ab.

Anyway, 4 and 5 would satisfy this, because 4+5 = 9 and 4*5 = 20. We can then factor the equation to (x+4)(x+5).

To solve (x+4)(x+5) = 0, we need to make either x+4 = 0 or x+5 = 0. That means x can be either -5 or -4.

Answer:

[tex]\frac 13[/tex]

Step-by-step explanation:

All three shows she likes are Hamilton, Aladdin, and Thriller.

But she can watch only two shows among the three shown.

The possible combination of the shows she can watch are

(Hamilton and Aladdin), (Aladdin and Thriller) and (Hamilton and Thriller).

So, the total number of possible events (available options)= 3.

As we have to determine the probability of watching Aladdin and Thriller, so here Aladdin and Thriller is the favorable event.

So, the number of favorable event=1

Now,

[tex]\text{Probability}=\frac{\text{Total number of possible events}}{\text{Total number of favorable events}}[/tex]

[tex]=\frac{1}{3}[/tex]

Hence, the probability that she sees Aladdin and Thriller is [tex]\frac 1 3[/tex].

Explanation:

The "per cupcake" means "for each cupcake" or "for 1 cupcake".

To get that initial "8 cupcakes" into "1 cupcake", we divide both given values by 8

The ratio 8 cupcakes : $32 then becomes 1 cupcake : 4 dollars

In other words, the unit cost is 4 dollars per cupcake.

Given:

The equation is

[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{4}{10}=\dfrac{2}{5}[/tex]

To find:

Whether the given equation is true or not.

Solution:

In addition of two fractions, we can not add numerator and denominator separately. First we need a common denominator, then we add numerators.

We have,

[tex]\dfrac{1}{2}+\dfrac{3}{8}[/tex]

Taking LCM, we get

[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{1\times 4+3}{8}[/tex]

[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{4+3}{8}[/tex]

[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{7}{8}\neq \dfrac{4}{10}[/tex]

So, the given equation is not true.

Therefore, the correct option is B.

The area under the shaded region from 1 to 2 is 0.14

Probabilities actually define the percentage of the happening of an event

Here the shaded region shows  the probability of the z-scores

The shaded region 1 to 2 is represented as:

[tex]P(1 < z < 2)[/tex]

By using the probability of z-score we can have

[tex]P(1 < z < 2)=P(z < 2)-P(z < 1)[/tex]

From the given standard normal table:

[tex]P(z < 2)=0.9772[/tex]

[tex]P(z < 1)=0.8413[/tex]

So, we have:

[tex]P(1 < z < 2)=0.9772-0.8413[/tex]

[tex]P(1 < z < 2)=0.1359[/tex]

The approximated value will be

[tex]P(1 < z < 2)=0.14[/tex]

Thus the area under the curve shaded is 1 to 2 is 0.14

The scale factor is the ratio of the second triangle length to the first triangle length. Then the scale factor is 8.

Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
