The ratio of men to women working for a company is 5 to 7. There are 276 employees in total. How many women work for the company?.

Answer: 10

Step-by-step explanation:

Total number of students = 113

we require to find the number of students who like both hockey and rugby.

number of students who like game = total number of students - students who doesn't like either one

= 113 - 18 = 95 = A ∪ B

So equation become

A ∪ B = A + B - A ∩ B

95 = 60 + 45 - A ∩ B

A ∩ B = 105-95 = 10.

The given line passes through points (0,4) and (-2,0) . So firstly we can find the slope of the line as ,

[tex]\longrightarrow m =\dfrac{y_2-y_1}{x_2-x_1}\\ [/tex]

[tex]\longrightarrow m =\dfrac{4-0}{0-(-2)}\\ [/tex]

[tex]\longrightarrow m =\dfrac{4}{2}\\ [/tex]

[tex]\longrightarrow m = 2 [/tex]

Now we may use point slope form of the line as ,

[tex]\longrightarrow y - y_1 = m(x-x_1)\\ [/tex]

[tex]\longrightarrow y - 4 = 2(x-0)\\ [/tex]

[tex]\longrightarrow y -4 = 2x \\ [/tex]

Step-by-step explanation:

A) Kristine have enough money to make the purchase.

B) She have left over $10.25 after the purchase.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Kristine has $150 to spend on school clothes.

The store is having a sale for 25% off.

Coupon= 10% off

So, Cost of three shirts = 3 x 35 = 105

Cost of pair of jeans = $40

Cost of pair of shoes = $70

So, She have to spend total = 105 + 40 + 70 = $215

After discount she have pay = 215 - 215 x 0.35

                                                = $139.75

Thus, Kristine have enough money.

Now, She would left with = 150- 139.75 = $10.25.

{(−2, 2), (−7, 7), (−1, 1), (−8, 8)} it is a function as every input has a single output. Therefore, option C is the correct answer.

In math, a relation defines the relationship between sets of values of ordered pairs. The set of elements in the first set are called domain which is related to the set of the element in another set, which is called range.

A) {(1, −7), (2, −8), (−2, 7), (1, 8)}

Since the element  1 corresponds to two different images i.e., -7 and 8. So, this relation is not a function.

B) {(−2, 1), (−7, −1), (2, 8), (−7, −8)}

Since the element -7 corresponds to two different images i.e., -1 and -8. So, this relation is not a function.

C) {(−2, 2), (−7, 7), (−1, 1), (−8, 8)}

It is a function as every input has a single output.

So, -2, -7, -1 and -8 are the elements of the domain of the given relation.

The area of trapezoid abcd is 164 cm2 with an altitude is 8cm, ab is 10 cm, and cd is 17 cm and bc=10cm

The area of a trapezoid can be calculated if the length of its parallel sides and the distance between them are given. The formula for the area of a trapezoid is expressed as,

A = ½ (a + b) h

where (A) is the area of a trapezoid, 'a' and 'b' are the bases and 'h' is the height.

Given that Area of trapezoid A=164 and the altitude is 8 cm, ab is 10 cm, and cd is 17cm.

Substitute these values in the formula:

164=8(BC+AD)/2

8(BC+AD)=328

BC+AD=41

Drop perpendiculars from B to AD and from C to AD and let them hit AD at E and F respectively. Note that each of these perpendiculars has a length of 8.

From the Pythagorean Theorem, AE=6 and DF=15 thus AD=BC+21. Substituting back into our original equation we have

The gradient of a line is a measure of how steep a straight line is. A line’s gradient might be positive or negative and does not have to be a whole integer.

Y=-3x-2

Y+2=(-3x-2)+2

Y+2=-3x-2+2

X = - (y + 2)/3

A line’s gradient is computed by dividing the difference in -coordinates by the difference in -coordinates. This is also known as the vertical divided by the horizontal, or the change in divided by the change in. Choose two points on the graph for a straight-line graph. Line gradient = (change in y-coordinate)/(change in x-coordinate). Of course, we can use this to determine the equation of the line.

Answer:

A scale model of a house uses a scale of 14 inches = 3 feet, this means that for every 14 inches in the model, it represents 3 feet in the actual house.

If the model is 4.25 inches tall, we can use this proportion to find the actual height of the house:

4.25 inches / 14 inches = x / 3 feet

To find the actual height of the house, we can cross-multiply and then divide:

(4.25 inches * 3 feet) / 14 inches = x

x = 1.5 feet

So the actual height of the house is 1.5 feet

In the given question,

If you have 25 members and wish to pick a president, secretary, and treasurer, then we have to find how many ways can we choose the officers, if individual members may hold more than one office.

We have a total of 25 members.

They have a total of 3 positions president, secretary, and treasurer.

When the one position of president was filled then there were left 24 members for the secretary position.

When the one position of secretary was filled then there were left 23 members for the treasurer position.

So the possible ways to fill the position are found by multiplying 25,24 and 23. So

Possible ways=25*24*23
