solve for x
2 + x^2 = 18​

Answers

Answer 1

Answer:

16

Step-by-step explanation:

Answer 2

Answer:

4 and -4

Step-by-step explanation:

To solve, just isolate x

2+x^2=18

subtract both sides of the equation by 2

x^2=16

find the square root of 16

(remember, no matter if a number is positive or negative, if it is squared, it automatically becomes positive)

to get:

x=4

and

x= -4

Since the triangle we are dealing with is an isosceles triangle if MNO is 80° that means angle <OMN and < NOM are equal. Take 180°- 80°= 100°. Then divide by two to get each angle to get 50°.

Greg bought a jacket for $35.23, a flag for $10.75, and a baseball cap for $17.25. He paid $50 and
the rest he borrowed from his friend. If Greg got $6.77 in change from the cashier, how much did he
borrow from his friend to pay for all the items?

Answers

Answer:

His friend gave Greg a 20$ bill.

Step-by-step explanation:

35.23+10.75+17.25=63.23

63.23-50= 13.23

13.23+6.77= 20

Answer:

He borrowed $6.46

Step-by-step explanation:

Add the totals up together. 35.23 + 10.75 + 17.25 to get 63.23

Subtract 50 from 63.23 (63.23 - 50.00) to get 13.23.

Subtract 6.77 from 13.23 (13.23 - 6.77) to get 6.46.

He borrowed $6.46 from his friend!

Step-by-step explanation:

To get the correct answer, you can count the total number of shaded tenths and the total number of shaded hundredths and then regroup.

There are 9 shaded tenths and 18 shaded hundredths. Regroup 10 hundredths into 1 tenth to get 10 tenths and 8 hundredths. Then regroup the 10 tenths in one whole, giving you 1 whole and 8 hundredths. The product is 1.08.

Another way to get the answer is to count the total number of shaded hundredths. There are 108 hundredths. Regroup 100 of them as one whole, giving you 1 whole and 8 hundredths.

b. What transformation maps square 2 onto square 3?
c. What transformation maps square 1 onto square 5?

Answers

Answer:

A) Translation

B) Reflection

C) Rotation

Step-by-step explanation:

The transformation types in mathematics are;

Reflection, translation, rotation and dilation.

We can see that the squares are all the same size, it's just the position of the stars that will aid us in knowing the specific transformation.

A) We can see that square 2 is the exact same thing as square 1. Just that it was shifted to the right of square 1. Thus, it was translated and the transformation is translation.

B) We can see that the star in square 3 is the exact mirror copy and location from square 2. Thus, this is a reflection.

C) We can see that the position of the star in square 5 is top while that in square 1 is at the left corner. This can only be achieved by rotation.

There are eight boys and six girls who are members of the trumpet section in the band. From the members of the trumpet section, a quintet is being formed. If the quintet must consist of three boys and two girls, how many quintets are possible?

Answers

Answer:

8 c  3     *   6 c 2 =   56 * 15  =   840 ways

Step-by-step explanation:

First, we consider how many ways there are to choose three boys from eight. There are 8 choices for the first boy, 7 for the second, and 6 for the third. However, because the boys are indistinct from one another, we have overcounted, and must divide by 3*2. Similarly, there are 6*5 ways to choose the two girls, divided by 2 for overcounting. Thus, there are (8*7*6*6*5)/(3*2*2)=840 possible quintets.

The height of the mural drawing is 9 inches while the length is 101.25 inches.

What is the scale factor?

You must specify the extent of the shape's enlargement when describing one.

The scale factor is the ratio of two dimensions such that one figure is large and another is small.

The scale factor is done due to the unpractical measurement of any figure.

Hight of the mural = is 12 feet

⇒ 12 × 12 = 144 inches.

Length of mural = 135 feet

⇒ 1620 inches.

Now,

She is using 3 cm for every 4 feet(4×12 = 48 inches)

Scale factor = 3/48 = 1 : 16

Now,

Length of mural drawing = 144/16 = 9 inches.

Height of mural drawing = 1620/16 = 101.25 inches.

Hence "The height of the mural drawing is 9 inches while the length is 101.25 inches".

A human's eyeball is shaped like a sphere with a diameter of 2.5 cm. A
dog's eyeball is shaped like a sphere with a diameter of 1.75 cm. About
how many times greater is the volume of a human's eyeball than the
volume of a dog's eyeball?

Answers

Answer:

I think it is 1.5

Step-by-step explanation:

I'm not that sure sorry :(

Volume of human eyeball is 3 times more than volume of dog's eye .

Given,

Human eyeball diameter = 2.5 cm

Dog eyeball diameter = 1.75 cm

Now,

Firstly calculate the volume of humans eye,

Volume of sphere = 4/3 πr³

r = radius of eyeball

r = d/2

r = 2.5/2

r = 1.25 cm

Volume = 2.60π cm³

Now calculate the volume of dogs eye,

V = 4/3 πr³

r = d/2

r = 1.75/2

r = 0.875 cm

V = 0.893π

Thus from the calculation volume of human eye is more by approximately 3 times .

At a recent charity event there was a range of admission charges:

Family (2 Adults + 2 Children)

Adult

Senior

Child (5 to 16 years)

Child under-5

$44

$14

$12

$10

Free

In addition it was possible to buy Family tickets before the event at the reduced cost of $40 per

family.

At the gate tickets to the value of $40 000 were purchased, and prepaid tickets added a further

$10000 to the total income. For every Family ticket sold on the day, 1 Adult, 1 Senior, and 3 Child

tickets were sold and 2 under-5 children were admitted free of charge.

How many people attended?

A

B

c

4400

4600

4650

5400

Answers

Answer:

5400

Step-by-step explanation:

Given data

Family (2 Adults + 2 Children) = $44

Adult = $14

Senior = $12

Child (5 to 16 years) = $10

Child under-5 = Free

At reduced price family buys ticket at = $40

Total prepaid ticket sold = $10,000

Value of ticket sold at the gate = $40,000

Determine how many people attended

first step : determine number of family that purchased the prepaid tickets

              = 10,000 / 40 = 250 families

∴  number people who booked prepaid tickets = 250 * 4 = 1000 people

Next step : Determine the number of families that booked the ticket at the gate

let the number of families = y

40,000 = 44 y + 12y + 3y * 10 + 14y + 2y *0

40,000 = y ( 100 )  hence y = 40,000 / 100 = 400

∴ number of people = 400 * ( 4 + 1 + 1 + 3 + 2 )  = 400 * 11 = 4400

Number of people whom attended = 4400 + 1000 = 5,400
