Step-by-step explanation:

They are similar triangles as all 3 angles are same

Answer:

C. The triangles are similar

Step-by-step explanation:

Similar means same figure/shape but not the same size, congruent is exactly the same. We can see that the two triangles are similar in shape, and if u want to go that fat, they have the same angles too. But they're not the same size so they are similar.

The sum of two numbers is 116 and their difference is 18. Find the larger number.

Answers

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Answer:

Step-by-step explanation:

let larger number be x and the other be y.

x - y = 18

x = 18+y

now, x + y = 116

therefore, 18+y+y= 116

18 + 2y =116

2y = 116-18

2y = 98

y = 98/2 = 49

larger number = 49 + 18 = 67

Answer: 3

Step-by-step explanation:

I just finished the test and this was the answer I put and it was right.

9x+6y=b

6y=b-9x

y=b/6 -9/6x

y=b/6-3x/2

y= -3x/2 +b/6

3x + 2y = 1

2y = 1 - 3x

y = 1/2 -3/2x

y = -3/2x + 1/2

What is the average rate of change in profit from Hour 5 to Hour 10?

Answers

Answer:

Step-by-step explanation:

so at 5 hours he was at a profit of 900 and 5 hours later he is at a profit 1500 then you can sub tract 900 from 1500 which gives you 600

$600 is the average rate of change in profit from Hour 5 to Hour 10

What is Rate of change?

A rate of change is a rate that describes how one quantity changes in relation to another quantity

The given table is

Hour Profit

0 $0

2.5 $500

5 $900

7.5 $1200

10 $1500

5 hours the profit is 900 and 5 hours later he is at a profit 1500

We need to subtract 900 from 1500 to find the average rate of change.

1500-900=600

Hence $600 is the average rate of change in profit from Hour 5 to Hour 10

Answers

Answer:

A, B and D

Step-by-step explanation:

The zeros of f(x) are the points located on the x- axis, that is where y = 0

We can check which ones are the solutions by finding the zeros of f(x)

To find the zeros let f(x) = 0 , that is

(x² + 2x - 8)(x - 6) = 0 ← factorise the quadratic

(x + 4)(x - 2)(x - 6) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 2 = 0 ⇒ x = 2

x - 6 = 0 ⇒ x = 6

There are 3 zeros at x = - 4, x = 2, x = 6

These are located at A, B and D

Answer:

A, D, B

Step-by-step explanation:

The roots (zeroes) are the x values where the graph intersects the x-axis. To find the roots(zeroes), replace y with 0 and solve for x.

Earl runs ___ meters per second.

Answers

Answer:

Earl runs 1.5 meters per second

Step-by-step explanation: 60 divided by 40= 1.5

Answer:

1.5 meters/s

Step-by-step explanation:

Since he runs 60 meters in 40 seconds, we can divide 60 by 40 to get how quickly he runs in meters/s. 60/40 = 6/4 = 3/2 = 1.5, so Earl runs 1.5 meters per second.

Find the constant of proportionality for the table and write in the form y = kx.

A) y = 1/6x
B) y = 6x
C) y = 7x
D) y = 42x

Answers

A is the correct answer.

Answer:

The constant of proportionality for the table will be: k=6

Thus, the equation becomes

[tex]y=kx[/tex]

[tex]y=6x[/tex]

Step-by-step explanation:

The constant of proportionality, k, is the constant value of the ratio of two proportional quantities y and x.

We know the equation

[tex]y=kx[/tex]

where k is the constant of proportionality.

Looking at the graph,

at x=7, the value of y=42

so the ratio of y/x = 42/7 = 6

at x=14, the value of y=84

so the ratio of y/x = 84/14 = 6

at x=21, the value of y=126

so the ratio of y/x = 126/21 = 6

at x=28, the value of y=168

so the ratio of y/x = 168/28 = 6

We observe that the ratio of y/x remains constant which y/x=6

so using the equation

[tex]y=kx[/tex]

take any point let say (7, 42)

42 = k(7)

42/7=k

6 = k

Therefore, the constant of proportionality for the table will be: k=6

Thus, the equation becomes

[tex]y=kx[/tex]

[tex]y=6x[/tex]

There are several bowls containing various amounts of grapes on a table. When 12 of the bowls each had 8 more grapes added to them, the mean (average) number of grapes per bowl increased by 6. How many bowls of grapes are on the table?

Answers

Answer:

There are 16 bowls

Step-by-step explanation:

Number of bowls = x

Total grapes added = 12 x 8 = 96

The average increased by 6

So 96/6 = 16

There were 16 bowls of grapes on the table

12 x 8 = 96

96/6=16

Answer:

16 bowls

Step-by-step explanation:

Number of bowls = x

Total grapes added = 12 x 8 = 96

The average increased by 6

So 96/6 = 16
