4 I think is the answer

Step-by-step explanation:

Step-by-step explanation:

Let the number of psychology books be 'x'.

and that of sociology books be 'y'.

x + y = 317 (given)

Number of sociology books sold was 89 less than that of psychology books.

y = x - 89

Which means,

x + x - 89 = 317

2x = 317 + 89

2x = 406

x = 406/2 = 203

y = 203 - 89 = 114

Hence, 203 psychology books and 114 sociology books were sold.

Answer:

1 notebook cost $2.27

Step-by-step explanation:

Multiply the unit cost of the pencils by how many pencils you have : ( 1.29*3 = 3.87)

Subtract this from the total cost ( 10.68 - 3.87 = 6.81)

Divide this by 3 since there are 3 notebooks

6.81 / 3 = $2.27

The bigger pizza has a diameter of 14 inches, or a radius of 14 / 2 = 7 inches.

The smaller pizza has a diameter of 12 inches, or a radius of 12 / 2 = 6 inches.

Step-by-step explanation:

The area of a circle is πR2 where R is the radius.

The difference in the size of the pizzas is  

Area of bigger pizza - Area of smaller pizza

= π(7 inches)2 - π(6 inches)2 = = 49π inches2 - 36π inches2 = 13π inches2  

The area of the large pizza is 13π inches² larger than the area of the medium pizza.

The bigger pizza has a diameter of 14 inches,

a radius = 14 / 2 = 7 inches.

The smaller pizza has a diameter of 12 inches.

radius = 12 / 2 = 6 inches.

The area of the circle is defined as the product of the pie and the square of the radius.

The area of the circle =πR²

The area of a circle is πR², where R is the radius.

The difference in the size of the pizzas = Area of bigger pizza - Area of smaller pizza

= π(7 inches)² - π(6 inches)²

= 49π inches² - 36π inches²

= 13π inches²

As a single power, we have the expression as (-24)^4

Step-by-step explanation:

Here, we want to write the expression into a single power

Using the indical laws, we have it that;

a^x/a^y = a^(x-y)

Thus, we have it that;

(-24)^5/-24 = (-24)^5-1 = -24^4

Answer:

a) (x + 14) + 3x = 90

b) m<1 = 33 degrees

m<2 = 57 degrees

Step-by-step explanation:

a) as we can see, the measure of angle 1 added to the measure of angle 2 will give 90 degrees

Mathematically, we have this as;

m<1 + m<2 = 90

Using the values of the angles given, we have it that;

(x + 14) + (3x) = 90

x + 14 + 3x = 90

4x + 14 = 90

4x = 90-14

4x = 76

x = 76/4

x = 19 degrees

b) if x = 19; then ;

m<1 = (19 + 14) = 33 degrees

m<2 = 3(19) = 57 degrees

Answer:

c i think this is thew answer

Step-by-step explanation:

If the area of the square is 20 m² then the side length of the square is √20 m. Then the correct option is B.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a square, opposite sides are parallel and all sides are equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

The area of a square is 20 m².

Then the area of the square s given as

Area = a²

where a is the side length of the square.

a² = 20

a = √20 m

The side length of the square is √20 m.

Answer:

henry gets 231

Step-by-step explanation:

my head

Answer:

231

Step-by-step explanation:

Let's consider that Gavin got X pounds.

Then Henry gets 3 times as much as Gavin => 3X

And Mark gets twice as much as Henry => 2 * 3X

Together they get 770, so:

X + 3X + 2*3X = 770

10X = 770  =>  X = 77

As we mentioned, Henry gets 3X, so

3X = 3 * 77 = 231

Length of beads altogether in the necklace = 3.75 cm

Step-by-step explanation:

Length of the beads used in a necklace = [tex]\frac{5}{4}[/tex] cm

Number of beads used in the necklace = 3

Therefore, length of beads in the necklace = Length of each bead × Number of beads used

= [tex]\frac{5}{4}\times 3[/tex]

= [tex]\frac{15}{4}[/tex]

= 3.75 cm

Length of the beads altogether in the necklace = 3.75 cm

Step-by-step explanation:

Marie would earn $37.2 in 4 1/2 hour.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas. This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Marie charges a $10.75 base fee for each dog she walks,

and, additional $7.10 per hour that she walks the dog.

Each day she spends $5.50 on dog treats.

So, if Marie works for 4 1/2 hour then she can earn

= 10.75 + 4 1/2 x 7.1 - 5.5

= 10.75 + 4.5 x 7.1 - 5.5

= $37.2.

Hence, Marie would earn $37.2.
