Find the value of x in the triangle above

Answer:

3x = 90, so x = 30.

2(30) + 3y = 90

60 + 3y = 90

3y = 30

y = 10

The correct answer is A.

Answer:

The probability of obtaining the sum of 10 is 1/12 or 0.0833

Step-by-step explanation:

Given

2 fair dice

Required

Probability of obtaining the sum of 10

To solve this, we have to list out the sample space.

Sample space is the total possible sum that can be obtained when she rolls the dice.

Let the first die be represented with S1 and the second be represented with S2.

S1 = {1,2,3,4,5,6}

S2 = {1,2,3,4,5,6}

To get the sample space, we have to add individual elements of S1 and S2.

This is done as follows.

When S1 = 1 and S2 = {1,2,3,4,5,6}

Sum = 1+1, 1+2, 1+3, 1+4, 1+5, 1+6

Sum = 2, 3, 4, 5, 6, 7

When S1 = 2 and S2 = {1,2,3,4,5,6}

Sum = 2+1, 2+2, 2+3, 2+4, 2+5, 2+6

Sum = 3,4,5,6,7,8

Using the same pattern as used above

When S1 = 3 and S2 = {1,2,3,4,5,6}

Sum = 4,5,6,7,8,9

When S1 = 4 and S2 = {1,2,3,4,5,6}

Sum = 5,6,7,8,9,10

When S1 = 5 and S2 = {1,2,3,4,5,6}

Sum = 6,7,8,9,10,11

When S1 = 6 and S2 = {1,2,3,4,5,6}

Sum = 7,8,9,10,11,12

Writing out the Sum, will give us the sample space.

Sample Space = {2, 3, 4, 5, 6, 7, 3, 4, 5, 6, 7, 8, 4, 5, 6, 7, 8, 9, 5, 6, 7, 8, 9, 10, 6, 7, 8, 9, 10, 11, 7, 8, 9, 10, 11, 12}

The sample space has a total of 36 elements

To calculate the probability of obtaining the sum of 10,

We have to count the number of 10's in the sample space

Number of 10 = 3

Probability = Number of 10 / Number of Sample Space

Probability = 3 / 36

Probability = 1/12

Probability = 0.0833

Hence, the probability of obtaining the sum of 10 is 1/12 or 0.0833

Answer:

3/36 = 1/12

Step-by-step explanation:

Total Outcome - 36

Possible Outcome - 4,6 5,5 6,4 : 3

Answer:

A. 9.85 inches

Step-by-step explanation:

In the graph we can see that 1 month has a rainfall of 0.4 in, 2 months have a rainfall of 0.5 in, 1 month has a rainfall of 0.6 in, 2 months have a rainfall of 0.85 in, 1 month has a rainfall of 0.95 in, 2 months have a rainfall of 1.0 in, 2 months have a rainfall of 1.05 in and 1 month has a rainfall of  1.1 in.

The total amount of rainfall in the desert that year was: 0.4 + 2*0.5 + 0.6 + 2*0.85 + 0.95 + 2*1.0 + 2*1.05 + 1.1 = 9.85 inches

Answer:

its 10.75 i'm pretty sure oops never mind i thought it was 1.5 its 1.05 my mistake the answer is 9.85!

Answer:

Add 4 to 17, then divide both sides by 3.

Step-by-step explanation:

Given that :

Suri's age is 4 less than 3 times her cousin's age

Suri is 17 years old

Let her cousin's age be c

Then ;

3c - 4 = 17

By adding 4 to 17; we have

3c = 17 + 4

3c = 21

Now, dividing both sides by 3 ; we have

3c/3 = 21/3

c = 7

The age of her cousin is 7 years

Answer:

Algebraic equation

Step-by-step explanation:

We would use an algebraic equation.

An algebraic equation is a mathematical statement in which two expressions are made equal to each other using the equal sign.

In this case the algebraic equation consists of constant, variables and algebraic operation.

One of the type of algebraic equation is a linear equation. The expression below relating suri's age with her cousin's is a linear equation.

We can derive equations from sentences that involves unknown values by representing them with variables such as x, y, etc.

Suri's age = 17years old

Let Suri's cousin's age = x

3 times her cousin's age = 3x

Suri's age = 4 less than 3 times her cousin's age = 3x-4

17 = 3x-4

3x = 17+4 = 21

x = 21/3

x = 7

Her cousins age = 3x = 3×7

Her cousins age = 21 years

Answer:

80 units

Step-by-step explanation:

Start with the rectangle of 8×6 which is 48.

Then start with a base, 2×6=12 and add 4, 2 per triangle. One base equals 16 and because it's 2 bases multiply by 2 equals 32.

32+48=80

The answer would be 80.

Final answer:

The bicycle should be worth a value of $79.16 after 6 years.

Explanation:

To calculate the value of the bicycle 6 years later, we need to find the depreciated price. The bicycle depreciates at a rate of 15% per year, so after 6 years, it will be worth 85% of its original value.

First, we calculate the value after one year: $250 * 0.85 = $212.50. Then, for each subsequent year, we multiply the previous year's value by 0.85 to calculate the new value.

Therefore, the bicycle should be worth $212.50 * 0.85 * 0.85 * 0.85 * 0.85 * 0.85 = $79.16 after 6 years.

Answer:

C. 50 deg

Step-by-step explanation:

m(arc)BDC = 260 deg

Since a full circle has an arc measure of 360 deg, we can find the measure of arc BC.

m(arc)BC = 360 deg - 260 deg = 100 deg

Angle 1 is formed by a tangent to the circle and a chord of the circle and has a vertex on the circle. Its measure is half the measure of the intercepted arc.

m<1 = (1/2)m(arc)BC = (1/2) * 100 deg = 50 deg

Answer: C. 50 deg

Answer:

I believe it's the second one

Step-by-step explanation:

A dilation factor of 1/2 and reflection across the x-axis that triangle JKL is dilated to form triangle  J'K'L' which is the correct answer would be an option (C)

Dilation is a process for creating similar figures by changing the size.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Here triangle JKL is dilated to form triangle J'K'L

Given that the coordinates for each of the shapes:

Regular:

J = -8, 6

K = -4, 6

L = -6, 2

Prime notation:

J' = -4, -3

K' = -2, -3

L' = -3, -1

We have to determine the dilation factor.

As we know dilation factor is the ratio of sides in the original image and the image after dilation.

Dilation factor = J'K'/JK

Dilation factor = 2/4 =  1/2

Hence, a dilation factor of 1/2 reflection across the x-axis that triangle JKL is dilated to form triangle  J'K'L'

Step-by-step explanation:

Answer:

6.3

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

When an expression is divided by its factor, there are no remainders.

Let's look at the number 6.

6= 1(6)= 2(3)

Thus, the factors of 6 are 1,2,3 and 6.

This is because 6 is divisible by all those numbers to give no remainders.

Let's look at the question again.

D. 2(x-a) is divisible by (x-a) since

[tex] \frac{2(x - a)}{x - a} = 2[/tex]

A.

[tex] \frac{ - (x + a) - 2}{x - a}[/tex]

This fraction cannot be simplified further

B.

[tex] \frac{ - 2(x + a)}{x - a} [/tex]

This fraction cannot be simplified either

C.

[tex] \frac{(x - a) + 2}{x - a} \\ = \frac{x - a}{x - a} + \frac{2}{x - a} \\ = 1 + \frac{2}{x - a} [/tex]

There is a remainder of 2 since 2 cannot be divided by (x-a). Thus, (x-a) is not a factor of this fraction.

Answer:

V = 136.1

Step-by-step explanation:

Use the formula [tex]V = \frac{1}{3}\pi r^{2} h[/tex]

The solution is,  the volume of the cone is 136.2inch^3.

The formula for the volume of a cone is ⅓ r2h cubic units, where r is the radius of the circular base and h is the height of the cone.

here, we have,

A cone has a radius of 5.1 inches

and a height of 5 inches.

we know,

Volume =  ⅓ r²h

             =136.2inch^3.

Hence, The solution is,  the volume of the cone is 136.2inch^3.

Answer:

b

Step-by-step explanation:

Answer:D

Step-by-step explanation:

Answer:

According to the picture, we can have the function form as:

y = ax^2 + bx + c

The y-intercept is (0, 2) => c = 2

=> y = ax^2 + bx + c

The x-intercept is (-2, 0)

=> 4a - 2b = 0 (1)

The graph goes through (1, 1.5)

=> a + b + 2 = 1.5

=> a + b = -0.5 (2)

From (1) and (2)

=> 4a - 2(-a - 0.5) = 0

=> 6a + 1 = 0

=> a = -1/6 => b = -0.5 - (-1/6) = -1/2 + 1/6 = -15/30 + 5/30 = -10/30 = -1/3

=> y = (-1/6)x^2 -(1/3)x + 2
