help i need the value of X

Answers

Answer:

x = 20

Step-by-step explanation:

The square signifies the angle is 90 degrees.

All triangle interior angles add up to 180 so:

2x + 10 + 40 + 90 = 180

2x + 140 = 180

2x = 180 - 140

2x = 40

x = 20

Answer:

20

Step-by-step explanation:

2x + 10 + 40 + 90 = 180

2x + 140 = 180

180 - 140 = 40

40 / 2

20

A discount of 15% is offered on an item which previously Cost $1.80. What is the discounted price​

Answers

The discounted price is $1.53

Amount saved is $0.27

Cost Price= CP= $1.80

Discounted Price = $ 1.53

Amount Saved= $ 0.27

Discount= 15%

The Discounted Price $ 1.53 is obtained after the discount percent applied to the cost price and subtracted from the cost price.

When the discounted price is subtracted from the Cost Price we get the amount saved.

Discount = discount % × Cost Price

Discount = 15% × $ 1.80 = $ 0.27

Discounted Price= Cost Price- Discount

                         = $1.8- $ 0.27= $ 1.53

One angle in an isosceles triangle measures 50°. Which of these cannot be the measure of an angle in this triangle? A 50 C 80% D130​

Answers

Answer:

In an isosceles triangle, 2 of the angles are identical

Sum of the 3 angles of a triangle is always 180

Possibility 1 - 50 is one of the 2 identical angles

The 3 angles will be 50, 50, (180-50-50)

Possibility 2 - 50 is not one of the 2 identical angles

The 3 angles will be 50, (180-50)/2, (180-50)/2

You can work out the above and see which answer is not the possible angle

Please let me know if you have further questions.

Answer:

D

Step-by-step explanation:

In an isosceles triangle two angles are equal to each other, single two sides are congruent. Since the sides of a triangle add up to 180, we can figure out possible answers. This means it could either be

50, 50 and 80

Or 50, 65, 65

Which means the impossible measure would be D 130.

Step-by-step explanation:

model car: $4.80/3 = $1.60

glue: $4.80/4 = $1.20

paint: $4.80/8 = $0.60

hot dog & soda: $4.80 - $1.60 - $1.20 - $0.60 = $1.40

7. There are 42 pupils in a class. 12 of them are Malays while the rest are
Chinese. 1/4 of the boys and 12 of the girls are Malay. How many boys
are there in the class?



I NEED THIS ASAP!!!

Answers

Answer:

There are 36 boys in the class.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

x is the number of boys

y is the number of girls.

There are 42 pupils in a class.

This means that [tex]x + y = 42[/tex].

Since we want x, we have that [tex]y = 42 - x[/tex]

12 of them are Malays while the rest are Chinese. 1/4 of the boys and 1/2 of the girls are Malay.

This means that:

[tex]\frac{x}{4} + \frac{y}{2} = 12[/tex]

Since [tex]y = 42 - x[/tex]

[tex]\frac{x}{4} + \frac{42 - x}{2} = 12[/tex]

Multiplying everything by 4.

[tex]x + 84 - 2x = 48[/tex]

[tex]-x = -36[/tex]

[tex]x = 36[/tex]

There are 36 boys in the class.

Let f(x)=√3x and g(x)=x-6 What's the smallest number that is in the domain of fog?

Answers

9514 1404 393

Answer:

  6

Step-by-step explanation:

Maybe you have ...

  f(x) = √(3x)

  g(x) = x-6

Then ...

  f(g(x)) = √(3(x -6))

The square root function is only defined for non-negative arguments, so we require ...

  3(x -6) ≥ 0

  x -6 ≥ 0 . . . . . divide by 3

  x ≥ 6 . . . . . . . . add 6

The smallest number in the domain of f(g(x)) is x = 6.

What is the effect on the graph of f(x) = 1 when it is transformed to
g(x) = 1 – 162
O A. The graph of f(x) is shifted 16 units up.
O B. The graph of f(x) is shifted 16 units to the left.
O C. The graph of f(x) is shifted 16 units down.
O D. The graph of f(x) is shifted 16 units to the right.

Answers

Answer: C) Shifted 16 units down

The minus 16 at the end is directly the reason why. Think of y = 1/x, and subtracting 16 from both sides to get y-16 = (1/x) - 16. The y-16 will shift every point down 16 units. For instance, the point (1, 1) moves to (1, -15).

Answers

Answer:

moderate positive relationship

Step-by-step explanation:

From the data:

The linear relationship between score and rating can be obtained by calculating the Pearson correlation Coefficient between the two variables. This can be obtained more easily by using technology, a linear correlation Coefficient calculator. The result of the correlation Coefficient for the data above is about 0.66. This value is positive which shows that the association between the variables is positive, increase in one leads to increase in the other and vice versa. Also the value shows that the relationship is fairly strong.
