Answer:

≈ 502

Step-by-step explanation:

The pie chart shows that shirts made up 11% of the sales made by the sporting goods store.

The number of sales that were shirts = 11% of the total sales

Total sales made by the store is given as 4,560

Number of sales that were shirts = 11/100 × 4,560

= 0.11 × 4,560

= 501.6

Number of sales made that were shirts is approximately 502.

Find the value of x so that the polygons have the same perimeter

mestny [16]

x - 2 + x + 4 + x - 2 + 4 - 4 = x + 3 + x + 4 + x + 5

4x + 4 = 3x + 12

4x - 3x = 12 - 4

x = 8

A 15-meter by 23-meter garden is divided into two sections. Two sidewalks run along the diagonal of the square section and along

Thepotemich [5.8K]

Solution:

We have re-drawn the given diagram, as we can see the given rectangle is actually divided into two parts.

one is Large square and the other one is a smaller rectangle.

Now we will apply the Pythagoras theorem in the larger triangle which is inside the square.

So we can write

$Diagonal_1=\sqrt{15^2+15^2}= 21.213$

Now we will apply the Pythagoras theorem in the smaller triangle which is inside the smaller rectangle.

So we can write

$Diagonal_2=\sqrt{15^2+8^2}= 17$

The approximate sum of the lengths of the two sidewalks, shown as dotted lines $=21.2+17=38.2$ m

Hence the correct option is D

I will mark you brainliest if its correctly

Step-by-step explanation:

sina = -√3/2

$\cos(a) = \sqrt{1 - { \sin(a) }^{2} }$

$= \sqrt{1 - { (\frac{ - \sqrt{ 3} }{2}) }^{2} }$

$= \sqrt{ \frac{4 - 3}{4} }$

$= \sqrt{ \frac{1}{4} }$

=±1/2

Since, π<a<3π/2

cos a = -1/2

$\tan(a )= \frac{ \sin(a) }{ \cos(a) }$

$\tan(a ) = \sqrt{3}$

A store is holding a sale during which all items will be sold at 30% less than their marked prices. How much will a rug marked $

IceJOKER [234]

Answer:

Cost of rug during sale = $140

Step-by-step explanation:

Given

Marked price of rug in a store = $200

The store is holding a sale and offering a flat 30% less on marked price on all items

This means the sale price of all items would decrease by 30%

We can calculate the discount offered by taking out percentage discount of the marked price.

Discount offered on rug = 30% of Marked price $=0.30\times200=\$60$

The discount is then subtracted from the marked price to get the price of rug during sale.

∴ Price of rug during sale = Marked price - Discount $=\$200-\$60 =\$140$
