[tex][Hello,BrainlyUser][/tex]

Answer:

[tex]1\frac{1}{15}[/tex]

Step-by-step explanation:

To Convert to a mixed number..

First, Let's add both fraction.

[tex]\frac{2}{15} + \frac{14}{15}[/tex]

The two fractions have like denominators so you can add the numerators.

[tex]\frac{2+14}{15}=\frac{16}{15}[/tex]

The fraction

[tex]\frac{16}{15}[/tex]

is the same as

[tex]16[/tex] ÷ [tex]15[/tex]

Convert to a mixed number using

long division for 16 ÷ 15 = 1R1, so

[tex]\frac{16}{15}=1\frac{1}{15}[/tex]

Therefore,

[tex]\frac{2}{15}+\frac{14}{15}=1\frac{1}{15}[/tex]

Hence, your answer is 1 1/15

The characteristics of the given points are observed during the

geometric construction processes.

Responses:

Step 1: The point O is the center because it is equidistant from the three points

Step 2: PQ = PR = QR, therefore, ΔPQR is an equilateral triangle

b) The ratio of a leg to the hypotenuse side of ΔACF is 0.5, therefore, ΔACF is a 30°– 60°–90° triangle

c) The points of intersection of the diameter and a  perpendicular bisector with the circumference of the circle are the vertices an inscribed square of the circle

Step 1: How to know that the point O is the center of the circle is as follows;

The perpendicular bisectors constructed are the locus of points

equidistant from the both points D and E and also the perpendicular

bisector gives the locus of points equidistant from points E and F

Therefore;

OE = OE, by reflexive property

OE is also equal to OF and OD by definition of the point O being on both

perpendicular bisectors.

Given that OE = OF = OD, we have that the point O is the center of a

circle with radius, OE = OF = OD passing through the points E, F, and D

Therefore;

Step 2: Given that the center of the circles are the points P and Q, we have;

PQ = The radial length of the two circles

Similarly

PR and QR are radial lengths of circle P and Q respectively

Therefore;

PQ = PR = QR

Which gives;

b) FC is the diameter of circle M

Therefore;

∠ACF is 90° and ΔACF is a right triangle

The ratio of the a leg to the hypotenuse side of a 30°– 60°–90° triangle is 0.5

Length of FA = FM = MC

[tex]\dfrac{FA}{FC} = \dfrac{FA}{FM + FC} = \dfrac{FA}{FA + FA} = \dfrac{FA}{2 \times FA} = \dfrac{1}{2} = \mathbf{0.5}[/tex]

Answer:

No, its not a right angle triangle. check for explanation below ↓

In order to figure whether ABC is a right-angled triangle.

First find the missing side:

22 - 8 - 5

9 cm

so the sides are 5 cm, 8 cm, 9 cm

using the rule:

short side² + short side² = biggest side²

5² + 8² = 9²

25 + 64 = 81

89 = 81

Thus found ABC is not a right-angled triangle.

[tex]AC = 22 - (8+5) = 22 - 13 = 9[/tex]

[tex]9^2 + 13^2 = 81 +169 = 250[/tex]

[tex]22^2 = 484[/tex]

So no, ABC is NOT a right triangle because the pythagorean thoerem fails

The probability that both pick the same number is p = 0.018

First, we need to count the number of options that each kid has.

Such that the common numbers in these two lists are:

We need to find the probability that both kids select one of these 3 numbers at the same time.

Then, Anna must select any of these 3 out of the 9 possibilities, so the probability for Anna is:

P = 3/9.

Then, Becky must select the same one than Anna, so there is only one number out of the 19 possibilities that she has, then the probability is:

Q = 1/19

The joint probability is given by the product between these 2 numbers, it is:

p = (3/9)*(1/19) = 0.018

Using a system of equations, it is found that the usual waiting time for the bumper cars is of 7.5 min.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

The waiting time for the roller coaster is usually 3 times as long as the waiting time for the bumper cars, hence:

x = 3y

The park's website says that visitors who go on both rides should expect to wait a total of 30 min, hence:

x + y = 30

Since x = 3y:

3y + y = 30

4y = 30

y = 30/4

y = 7.5.

The usual waiting time for the bumper cars is of 7.5 min.

Answer:

Step-by-step explanation:

Value of √3025 by Long Division Method

Forming pairs: 30 and 25

Find a number Y (5) such that whose square is <= 30. Now divide 30 by 5 with the quotient as 5.

Bring down the next pair 25, to the right of the remainder 5. The new dividend is now 525.

Add the last digit of the quotient (5) to the divisor (5) i.e. 5 + 5 = 10. To the right of 10, find a digit Z (which is 5) such that 10Z × Z <= 525. After finding Z, together 10 and Z (5) form a new divisor 105 for the new dividend 525.

Divide 525 by 105 with the quotient as 5, giving the remainder = 525 - 105 × 5 = 525 - 525 = 0.

We stop the process since the remainder is now 0 and there are no more digits that can be brought down.

Therefore, the square root of 3025 by the long division method is 55.

Answer:

x= 10

Step-by-step explanation:

We can use the fact that the sum of all angles in a triangle is 180°.

5x +7x +60 = 180

Solve for x, because we have 1 equation with 1 unknown

   5x +7x +60 = 180, combine like terms

       12x + 60 = 180. subtract 60 from both sides of the equation

12x + 60 -60  = 180 -60, combine like terms

                12x = 120, divide both sides by 12

                   x = 10

The number of days you would expect rain is 12 days in April.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

Probability of rain in april= 40%

Days=30

Now,

To answer this question, you need to use the formula for expected value:

Expected value = probability × number of trials

In this case, the probability of rain is 40%, which can be written as 0.4 in decimal form. The number of trials is the number of days in April, which is 30.

Plugging these values into the formula, we get:

Expected value = 0.4 × 30 = 12

Therefore, by probability the answer will be 12 days in April.

C = (12, 13)

Step-by-step explanation:

The centre of the rectangle is O.

Find the difference between the x and y-values of O and A:

[tex]O_x-A_x=\dfrac{21}{2}-9=\dfrac32[/tex]

[tex]O_y-A_y=\dfrac{19}{2}-6=\dfrac72[/tex]

Now add those difference to the coordinates of O to find C:

x value of C = [tex]O_x+\dfrac32=\dfrac{21}{2}+\dfrac32=\dfrac{24}{2}=12[/tex]

y value of C = [tex]O_y+\dfrac72=\dfrac{19}{2}+\dfrac72=\dfrac{26}{2}=13[/tex]

Therefore, the coordinates of C = (12, 13)

Answer:

Step-by-step explanation:

In rectangle the diagonals bisect each other. So,O is the midpoint of AC

[tex]Midpoint = \left(\dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{2} \right)\\\\\\x_{1}=9 \ and \ y_{1}=6\\\\\left(\dfrac{9+x_{2}}{2},\dfrac{6+y_{2}}{2} \right) = \left (\dfrac{21}{2},\dfrac{19}{2} \right)[/tex]

Compare the x- coordinates and y- coordinates

[tex]\dfrac{9+x_{2}}{2}=\dfrac{21}{2} \ ; \ \dfrac{6+y_{2}}{2}=\dfrac{19}{2}\\\\\\9+x_{2}=\dfrac{21}{2}*2 \ ; \ 6 +y_{2}=\dfrac{19}{2}*2[/tex]

9 + x₂ = 21         ;  6 +y₂ = 19

     x₂ = 21 -9     ;       y₂ = 19 - 6
