the slope of the hill? (You must reduce fractions)
3/7
3/2
7/3
-7

Answer:

Step-by-step explanation:

8x-192=96

8x-192+192=96+192

8x=288

8x/8=288/8

x=288/8

36

The unknown number is 204.

Important Information:

Let [tex]x[/tex] be the unknown number.

Sum of a number and -192 is

[tex](x+(-192))=x-192[/tex]

Eight times the sum of a number and -192 gives 96.

[tex]8(x-192)=96[/tex]

Divide both sides by 8.

[tex]x-192=12[/tex]

[tex]x=12+192[/tex]

[tex]x=204[/tex]

Therefore, the unknown number is 204.

Step-by-step explanation:

6.

Triangles TUV and TWV are congruent triangles.

Angles U and W are corresponding angles, so they are congruent.

m<U = m<W

7x + 15 = 8x

Subtract 7x from both sides.

15 = x

m<U = 7x + 15 = 7(15) + 15 = 8(15) = 120

Required

Which pair makes the relation not a function?

A function is defined as:

[tex]\{(x_1,y_1), (x_2,y_2), (x_3,y_3)..... (x_n,y_n)\}[/tex]

Where each x values (domain) are unique and different from one another.

In the given function, the x values (domain) are: -3, 1 and 4

To get a pair that makes the relation, not a function; we have to select from the given options, any option that has either of -3, 1 and 4 as its x values.

From the list of given options.

Answer:

Result is significant ; hence we can conclude that the average age of male is greater than that of females.

Step-by-step explanation:

Given that:

Let :

u1 = mean age of male

u2 = mean age of female

Null hypothesis : H0 : u1 = u2

Alternative hypothesis : H1 : u1 > u2

P value for hypothesis test conducted = 0.0095

Using a significant level α 0.05 or 0.01, :

The P value < α

Since, the P-value is less than α, then the result is significant and we thus we can reject the Null and conclude that the average age of males is greater Than that of females that play on the golf course.

AB = √18 , BC=√18 and CA =4

AB²+BC²  = CA² and AB=BC

ΔABC isosceles right  angled triangle.

Step-by-step explanation:

Given vectors are  7j+ 10k,-i + 6j+6k and - 4i + +9j + 6k

A( 0,7,10), B( -1,6,6) C(-4,9,6)

AB⁻ = OB-OA = -I+6j+6k-(7j+10k) = -I-j-4k

AB = [tex]\sqrt{1+1+16} = \sqrt{18}[/tex]

BC = OC-OB = -4i+9j+6k-(-I+6j+6k) = -3i+3j

BC=[tex]\sqrt{9+9} =\sqrt{18}[/tex]

CA = OA-OC = 7j+10k - (- 4i + +9j + 6k ) = 4i-2j+4k

CA = [tex]\sqrt{16+4+16} =\sqrt{36} =4[/tex]

Since AB²+BC²  = CA²

And AB=BC

Therefore it follows that ΔABC is a right angled isosceles triangle



Answer:

yellow 9/25

yellow and green is 14/25

Using it's concept, it is found that the probabilities are given as follows:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, 9 out of 25 are yellow, then 5 out of 24 will be green, hence:

P(yellow, then green) = 9/25 x 5/24 = 45/(25 x 24) = 0.075 = 7.5%.

For both blue, we have that they are, respectively, 6 out of 25 and 5 out of 24, hence:

P(both blue) = 6/25 x 5/24 = 30/(25 x 24) = 0.05 = 5%.

Answer:

The total distance of the outer sides of a closed figure is known as the perimeter. It is the total length of all sides of a polygon. Perimeter = Sum of all sides.

Formula:

The sum of interior angles of a polygon with “n” sides =180°(n-2) Number of diagonals of a “n-sided” polygon = [n(n-3)]/2. The measure of interior angles of a regular n-sided polygon = [(n-2)180°]/n. The measure of exterior angles of a regular n-sided polygon = 360°/n.

Answer:The ratios are _Equivalent_______.

Step-by-step explanation:

Step 1

Equivalent ratios are ratios that have the same value  even though they look different. When we divide or multiply  a given ratio by the same  number ( in the numerator and denominator )we get anther equivalent ratio.

Step 2

In the given ratios

8/11 and 24/ 33

8/ 11  x 3/ 3 = 24/ 33

also

24/33 ÷ 3/3 = 8/11

This shows that the relationship between the  ratios are equivalent.

Answer:

[tex]c = 65[/tex]

[tex]x = 158[/tex]

Step-by-step explanation:

In the first triangle, one of the angles are already given to us, the 25. But the other angle is 90 degrees because it's a right angle. A right angle measures 90 degrees. We now add both the numbers together and subtract it from 180 to find the answer. We are subtracting it from 180 because a triangle equals 180 degrees.

[tex]90 + 25 = 115 \\ 180 - 115 = 65[/tex]

In the second triangle, one of the angles are already given to us, the 68. But the other angle is 90 degrees because it's a right angle. A right angle measures 90 degrees. We now add both the numbers together and subtract it from 180 to find the answer. We are subtracting it from 180 because a triangle equals 180 degrees.

[tex]68 + 90 = 158 \\ 180 - 158 = 22[/tex]

We figured out all the angles inside the triangle.

68, 90, and 22. We need to find the exterior angle. Remmeber that Consecutive angles are supplementary. The 22 and the x are one a straight line. A straight line equals 180 degrees. You are going to subtract 22 from 180 to get your answer.

[tex]180 - 22 = 158[/tex]

If you wanted to write it as an equation and solve it, it would be:

[tex]22 + x = 180[/tex]

=============================================

Work Shown:

Apply the law of cosines

a^2 = b^2 + c^2 - 2*b*c*cos(A)

10^2 = 13^2 + 11^2 - 2*13*11*cos(A)

100 = 290 - 286*cos(A)

100-290 = -286*cos(A)

-190 = -286*cos(A)

190 = 286*cos(A)

286*cos(A) = 190

cos(A) = 190/286

A = arccos(190/286)

A = 48.368620460647

A = 48

Step-by-step explanation:

Answer:

The three consecutive POSITIVE ODD integers are: 3, 5 and 7

Step-by-step explanation:

If x is an integer, then there consecutive positive odd integers are:

x , x + 2, x + 4 are three consecutive integers.

Where

First integer, a = x

Second integer, b = x + 2

Third integer, c = x + 4

We are told to:

Find three consecutive POSITIVE ODD integers such that when you multiply the first and third the result is nine less than six times the second integer.

Hence, this is represented as:

a × c = 6(b) - 9

Where

a = x

b = x + 2

c = x + 4

x (x + 4 ) = 6(x + 2) - 9

x ² + 4x = 6x + 12 - 9

x² +4x - 6x - 12 + 9= 0

x² - 2x - 3 = 0

Factorising

x² +x - 3x - 3 = 0

x (x + 1) -3(x + 1) = 0

(x - 3) (x + 1) = 0

x - 3 = 0

x = 3

x + 1 = 0

x = -1

Since, x cannot be negative for this question, x = 3

First integer, a = x = 3

Solving for:

Second integer, b = x + 2

b = 3 + 2 = 5

Solving for :

Third integer, c = x + 4

c = 3 + 4 = 7

Therefore, the three consecutive POSITIVE ODD integers are: 3, 5 and 7
