Answer:

$7.74

Step-by-step explanation:

The school buys 350 books. These books, in total, costed the school $1137.50. The school wants to make a profit of $1500.

For the school to make a profit on its purchase, it needs to earn $1500 more than the price that they paid for the books.

This means that we can add these values together to get the minimum amount that the school needs to earn

[tex]1137.50+1500=2637.50[/tex]

Now that we have the minimum value, we can divide this by 350 in order to find the minimum price for each individual book.

[tex]\frac{2637.50}{350} =7.7357=7.74[/tex]

This means that the school needs to sell these books for at least $7.74

(... This fictional school is selling the books for more than double the price they paid for them...)

Answer:

20

Step-by-step explanation

not sure but looks like you need help as fast as possible here my answer the way i thought about is you have 70 degree angle and y looks like a right angle which = 90 degree

x = 180 - 70+90

x = 180 - 160

x = 20

The value of the angle x for the given triangle will be 20°.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

As per the given triangle,

m∠y = 90°

The exterior angle = sum of two interior angles except for the adjacent angle of the exterior angle.

110° = x + y

110° = x + 90°

m∠x = 20°

Hence "The value of the angle x for the given triangle will be 20°".

Answer:

First problem: 1088 [tex]m^{3}[/tex]

Second problem: 554.3 [tex]m^{3}[/tex]

Step-by-step explanation: Please see the images below!

The volumes of both the pyramids are 1088 m³ and 554.3 in³.

The volume of a shape or solid is the space occupied by it, which also includes its height or depth.

a) To find the volume of the pyramid, first calculate the area of the base.

B = lw

Substitute 16 for l and 12 for w.

B = 16 ⋅ 12

Simplify.

B = 192 m²

To find the volume of the pyramid, use the formula for the volume of a pyramid.

V = 1/3 Bh

Substitute 192 for B and 17 for h.

V = 1/3 ⋅ 192 ⋅ 17

Simplify.

V = 1088 m³

Therefore, the volume of the rectangular pyramid is 1088 m³.

b) Similarly for the volume of a regular hexagonal pyramid with base edge length 8 in. and height 10 in.

Base area = 96√3 in²

Volume = 1/3 × 96√3 in² × 10 in

= 554.3 in³

Hence, the volumes of both the pyramids are 1088 m³ and 554.3 in³.

Step-by-step explanation:

We have been given that a rectangular​ prism-shaped room is 18 ft by 10 ft and 8 ft high. We are asked to find the gallons of paint needed to paint the walls of room.    

Answer:

Highest Elevation: 14240

Lowest Elevation: -285

Step-by-step explanation:

Given

[tex]Highest\ Elevation = 14,240\ ft[/tex] above sea level

[tex]Lowest\ Elevation = 285\ ft[/tex] below sea level

Required

Represent both altitudes as an integer

For the Mountain:

Take the sea level as 0 feet

[tex]Altitude = Highest\ Elevation - Sea\ Level[/tex]

[tex]Altitude = 14240 - 0[/tex]

[tex]Altitude = 14240[/tex]

Hence, the integer is 14240

For the Valley:

Take the sea level as 0 feet

[tex]Altitude = Sea\ Level - Lowest\ Elevation[/tex]

[tex]Altitude = 0 - 285[/tex]

[tex]Altitude = -285[/tex]

Hence, the integer is -285

Answer & Step-by-step explanation:

Regression studies the relationship between independent / explanatory  (causal) variable, dependent / response (effected) variable. Scatter plot is a diagrammatic representation of regression.

Aspartame Concentration, being a toxic substance, is likely to have negative regression relationship with mice survival rate. It implies that higher concentration leads to lower mice survival, & lower concentration leads to higher mice survival.

The relationship can be strong or weak, depicted by 'r' magnitude, depending upon the intensity of concentration impact on survival. If more percent of the variation in survival rate can be explained by variations in  concentrations, regression coefficient is high. If less percent of the variation in  survival rate can be explained by variations in concentrations, regression coefficient is low

Answer:

let the three numbers be x,y,z

X= z-6

Y= 4z

Z= z

Step-by-step explanation:

X+Y+Z=114

hence

=z-6+4z+z=114

=collect like times. X= 20-6=14

= z+4z+z=114+6. Y= 20*4=80

=6z=120. . Z= 20

z=20

Answer:

  14 + 20 + 80 = 114

Step-by-step explanation:

Let's begin by representing our 1st number as x.

Then our 2nd number is said to be 6 more than the 1st number, which we can represent as x + 6.

Lastly, our 3rd number is said to be 4 times the 2nd number, which we can represent as 4(x + 6).

Now can write our equation to express the sum of these three numbers as 114 and then solve for x to find the values of these three numbers:

   x + (x + 6) + 4(x + 6) = 114

   x + x + 6 + 4x + 24 = 114

   6x + 30 = 114

   6x = 114 - 30

   6x = 84

     x = 84/6 = 14 (1st number)

     x + 6 = 14 + 6 = 20 (2nd number)

     4(x + 6) = 4(20) = 80 (3rd number)

We can check our answers by adding these numbers up to see if their sum is 114:

    14 + 20 + 80 = 114

    34 + 80 = 114

    114 = 114

Their sum is 114, so we are confident that our three numbers are correct.

Answer:

8000

Step-by-step explanation:

198 and 42 rounded to the nearest hundreths are 200 and 40. the product of 200 and 40 is 8000

The product of 198 and 42 rounded both numbers to the nearest ten

is 8000.

We round off numbers to make them easier to remember and it also keeps its value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, Use rounding to estimate the product of 198 and 42.

Now, 198 rounded to the nearest ten is 200, and 42 rounded to the nearest ten is 40.

Therefore, The multiplication of 198 and 42 rounded to the nearest 10 is,

= 200×40.
