Suppose y varies directly as x, and y=26 when x=8. Find x when y=65.

Answers

Answer:

when y=65, x=20

Step-by-step explanation:

We are given:

y varies directly as x

and y=26, when x=8

We need to find x, when y = 65

y varies directly as x can be written as:

[tex]y\:\alpha \:x\\y=kx[/tex]

Where k is constant of proportionality.

Finding k, when y=26 and x=8

[tex]y=kx\\26=k(8)\\k=\frac{26}{8}\\k=3.25[/tex]

We get the value of k = 3.25

Now, we need to find value of x, when y=65 and k=3.25

[tex]y=kx\\65=3.25(x)\\x=\frac{65}{3.25}\\x=20[/tex]

So, when y=65, x=20

Here are the marks of a student in four exams. 65 80 76 69 The student takes a fifth exam. His mean mark for the five exams is 70 Work out his mark in the fifth exam

Answers

Answer:

mark of the fifth exam = 60

Step-by-step explanation:

Mean = sum of all marks / number of exam

Mean = 70

Number of exam = 5

Let x =

Mean = sum of all marks / number of exam

70 = (65 + 80 + 76 + 69 + x) / 5

Cross product

70 × 5 = (290 + x)

350 = 290 + x

350 - 290 = x

x = 60

mark of the fifth exam = 60

Explanation:

1. You are given the statement "A is B". In "if-then" form, it can be written, "if it is A, then it is B."

If it is broccoli, then it is a vegetable.

2. The hypothesis is the "if-" part:

(If) it is broccoli

3. The conclusion is the "then-" part:

(then) it is a vegetable

4. The converse interchanges the hypothesis and conclusion:

If it is a vegetable, then it is broccoli.

5. The converse is false. A potato is a vegetable, but is not broccoli.

6. The inverse negates the hypothesis and conclusion:

If it is not broccoli, it is not a vegetable.

7. The inverse is false. A potato is not broccoli, but is a vegetable.

8. The contrapositive is the inverse of the converse:

If it is not a vegetable, it is not broccoli.

9. The contrapositive has the same truth value as the original statement. Here, it the contrapositive is true.

Marcie likes to collect stickers, but she also likes to give them away. Currently, Marcie has 87 stickers in her collection. If Marcie collects 5 new stickers each week and gives away 3 stickers each week, how many stickers will Marcie have in her collection after 5 weeks?

Answers

Answer: 97 stickers

Step-by-step explanation:

Marie has 87 stickers in her collection.

Each week she collects 5 and gives away 3.

The total number of stickers she gains per week is therefore:

= 5 - 3

= 2 stickers per week

In 5 weeks therefore, she would have collected:

= 2 * 5

= 10 stickers

Add that to the original number:

= 87 + 10

= 97 stickers

In which choice do all three points lie on the same straight line?
A. (0,0) (1, 1) (2, 4)
B. (5, 1) (-3,0) (-1,2)
C. (2, 10) (4.9) (5,8)
D. (0.1) (2,3) (4,5)

Answers

Answer:

D) (0,1) (2,3) (4,5)

Step-by-step explanation:

Explanation

Given Points are A(0,1) , B(2,3) , C(4,5)

slope of the AB

[tex]= \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{3-1}{2-0} =\frac{2}{2} =1[/tex]

Slope of BC

[tex]= \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{5-3}{4-2} =\frac{2}{2} =1[/tex]

Therefore slope of AB and BC are equal

The three points lie on same straight line

The three points are collinear points

Triangle ABC was reflected over line m, then dilated by a scale factor between 0 and 1. Which diagram illustrates these transformations?

Answers

The transformation is better described by: Triangle A B C is reflected across line m and then is dilated to form smaller triangle A double-prime B double-prime C double-prime

What is transformation?

In mathematics, transformation is manipulating a figure on a plane or coordinate system.

In this case the manipulation involves reflection and scaling to a factor between 0 and 1

scaling to factor 0 means the triangle disappeared

scaling to factor 1 means the triangle remained same size

factors between 0 and 1 means reduction of size.

since the transformation did not rotate the triangle it makes the first option the correct answer

Answer:

21.4

Step-by-step explanation:

For this problem, you only need to know that the hypotenuse (x) is the longest side of the triangle. The only answer choice longer than 20 is ...

x = 21.4

If you want to actually go through the numbers, you know that ...

Cos = Adjacent/Hypotenuse

cos(21°) = 20/x

x = 20/cos(21°)

x ≈ 21.4

Step-by-step explanation:

The length of the two legs of a right triangle are 18 cm and 24 cm.
What is the length of the hypotenuse of the triangle?
O A. 30 cm
OB. 36 cm
OC. 42 cm
D. 48 cm

Answers

Answer: 30 cm

Step-by-step explanation: Take note that ^2 means to the second power.

a^2 + b^2 = c^2 (hypotenuse)

18^2 + 24^2 = c^2

324 + 576 = c^2

900 = c^2

To find the length of c you have to find teh square root of 900.

√c^2 = √900

c = 30

The length of the hypotenuse is 30 cm!
