Answer:

418.6

Step-by-step explanation:

you set the price to equal 300 dollars, so marking up 40% would equal taking 300 x 1.4

this equals 420, however you need to substract 1.4 because you rounded 299 to 300 giving 418.6

Answer:

299 ×40%=119.6

so the final price is 299+119.6=418.6

Answer:

22.14

Step-by-step explanation:

Since perimeter is all around the easy part will be adding the trapazoids sides which add up as

11 + 4 + 4 = 19

when it comes to the semi circle you have to figure out the circumfrence

circumfrence = πd = π2

however because it is a semi circle you will need half of the circumfrence

π2 / 2 = π

so then you add the total to get

11 + 4 + 4 + 3.14 = 22.14

Answer:

-2+10=8

Step-by-step explanation:

Answer:

AB is perpendicular to IB

A pair of segment that are marked perpendicular to each other are JC and CD.

As per the figure given,

∠JCD = 90°

In geometry, when it's stated that angle JCD is 90°, it means that angle JCD is a right angle. When two line segments or rays intersect to form a right angle, it indicates that they are perpendicular to each other.

In the context of the figure given, JC is a line segment , and CD is another line segment. The fact that angle JCD is a right angle (90°) tells that JC is perpendicular to CD.

Hence, as angle JCD is given as 90°, it establishes that JC is perpendicular to CD in the context of the figure given.

Answer:

21

Step-by-step explanation:

One number is 3 times another

x and 3x

difference between the numbers is 14,

3x - x = 14

simplify

2x = 14

Divide both sides by 2

x = 7

3x = 21

Answer:

The larger number is 21.

Step-by-step explanation:

let, the smaller number be x.

the larger number be 3*x =3x.

Now,

3x-x=14

or, 2x=14

or, x=14/2

x=7

here,

3x=3*x=3*7=21

Answer:

slope =4

Step-by-step explanation:

from, y=mx + c

where m is slope

Answer:

the slope formula is y=mx+b where b is the y intercept and m is the slope we rewrite the equation by subtracting 4x from either side and then dividing both sides by 6 so we have y=-0.6x+2 so m the slope is -0.6

Answer:

{g,h} = {-9/5,32/5}

Step-by-step explanation:

h = 2g + 10

3g + (2g+10) = 1

[1]    5g = -9

5g = - 9  

g = - 9/5

g = -9/

h = 2g+10

h = 2(-9/5)+10 = 32/5

{g,h} = {-9/5,32/5}

Answer:

p(7) = 57

Step-by-step explanation:

Because this is a function, all you have to do is input 7 for x like so:

p(x)=x^2+x+1 --------------->     p(7)=7^2+7+1

                                            so 49 + 8

Answer:

192

Step-by-step explanation:

The length is 8.3 and the width is 7.5

8.3 to the nearest whole number is 8

7.5 to the nearest whole number is 8

8 x 8 = 64

64 x 3 = 192

The whole area of the wall that Alyssa painted is 192 ft²

The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.

Given that, Alyssa paints 3 walls blue. Each of the walls is 8.3 feet tall and 7.5 feet wide.

Since, the length is 8.3 and the width is 7.5

8.3 to the nearest whole number is 8

7.5 to the nearest whole number is 8

Therefore, area = length × width

= 8 x 8 = 64 ft²

Area of 3 walls =

64 x 3 = 192 ft²

Hence, the whole area of the wall that Alyssa painted is 192 ft²
