Answer:

C. Obtuse.

Step-by-step explanation:

We are asked to classify the type of angle 2.

We can see that measure of angle 2 is neither a straight line nor a right angle.

We can also see that measure of angle 2 is greater than 90 degree, therefore, angle 2 is not an acute angle.

Since the measure of angle 2 is greater than 90 degrees, therefore, angle 2 is an obtuse angle.

Answer:

m∠Q = 61°

m∠S = 61°

m∠R = 58°

Step-by-step explanation:

Since we have an isosceles triangle, we know that ∠Q and ∠S are congruent.

Step 1: Definition of isosceles triangle

2x + 41 = 3x + 31

41 = x + 31

x = 10

Step 2: Find m∠Q

m∠Q = 2(10) + 41

m∠Q = 20 + 41

m∠Q = 61°

Step 3: Find m∠S

Since m∠Q = m∠S,

m∠S = 61°

Step 4: Find m∠R (Definition of a triangle)

Sum of angles in a triangle adds up to 180°

m∠R = 180 - (61 + 61)

m∠R = 180 - 122

m∠R = 58°

five and three-tenths times a number plus two and seven-tenths is less than three and three-tenths times a number plus one and s

love history [14]

The number according to the given statement is x<-0.55.

Given the statement is five and three-tenths times a number plus two and seven-tenths is less than three and three-tenths times a number plus one and six-tenths.

A mathematical statement is a meaningful component of words that can be true or false. Simply, they are known as a statement.

Let us assume the given number be x.

According to the given statement,

Five and three-tenths of a number means 5.3x.

And two and seven-tenths means 2.7.

So, five and three-tenths times a number plus two and seven-tenths means 5.3x+2.7. ......(1)

It is also given that three and three-tenths times a number means is 3.3x.

And one and six-tenths means 1.6.

So, three and three-tenths times a number plus one and six-tenths means 3.3x+1.6 .......(2)

Now, we will substitute equation (1) less than equation (2) according to the given statement is

5.3x+2.7<3.3x+1.6

Further, we will subtract 2.7 from both sides, we get

5.3x+2.7-2.7<3.3x+1.6-2.7

5.3x<3.3x-1.1

Now, we will subtract 3.3x from both sides, we get

5.3x-3.3x<3.3x-1.1-3.3x

2x<-1.1

Now, we will divide both sides by 2, we get

2x/2<-1.1/2

x<-0.55

Hence, the number for the given statement "five and three-tenths times a number plus two and seven-tenths is less than three and three-tenths times a number plus one and six-tenths" is -0.55.

Readme [11.4K]

Answer:

a) (1,2), (1,3), (1,4), (1,5), (2,3), (2,4),(2,5),(3,4), (3,5) and (4,5)

PX(0) = 0.3

PX(1) = 0.6

PX(2) = 0.1

F(x) = 0 if x<0
F(x) = 0.3 if 0 ≤ x < 1
F(x) = 0.9 if 1 ≤ x < 2
F(x) = 1 if x ≥2

Step-by-step explanation:

Lets call the boards 1,2,3,4 and 5

a) There are ${5 \choose 2} = 10$ possible outcomes: (1,2), (1,3), (1,4), (1,5), (2,3), (2,4),(2,5),(3,4), (3,5) and (4,5).

b) X is 0 if the selected boards doesnt contain 1 or 2. There are ${3 \choose 2} = 3$ possibilities for this, in concrete, (3,4), (3,5) and (4,5).

PX(0) = 3/10 = 0.3

There is only 1 possibility so that X = 2, which is (1,2), therefore

PX(2) = 1/10 = 0.1

In any other case (there are 6 remaining), X will be equal to 1, so

PX(1) = 6/10 = 0.6

Therefore, X has the following distribution

PX(0) = 0.3

PX(1) = 0.6

PX(2) = 0.1

c) F(0) = 0.3

F(1) = 0.3+0.6 = 0.9

F(2) = 1

We have, as a consequence

F(x) = 0 if x<0
F(x) = 0.3 if 0 ≤ x < 1
F(x) = 0.9 if 1 ≤ x < 2
F(x) = 1 if x ≥2

The formula for finding the perimeter, P, of a rectangle with length l and width w is given. P=2l+2w

Ivenika [448]

Answer:

The formula to determine the length of rectangle with perimeter and width is L = $\frac{P - 2W}{2}$

Step-by-step explanation:

Given as :

The perimeter of rectangle = P

The length of rectangle = L

The width of rectangle = W

∵ Perimeter of rectangle given as P = 2 × Length + 2 × Width

I.e P = 2 L + 2 W

Or, 2 L = P - 2 W

∴ L = $\frac{P - 2W}{2}$

Hence The formula to determine the length of rectangle with perimeter and width is L = $\frac{P - 2W}{2}$ Answer
