Peterson will need 39 more tiles to completely cover the kitchen floor

Step-by-step explanation:

Given dimensions of kitchen are:

12 feet and 7 feet

In order to find the number of tiles for the kitchen, we have to first find the area of the kitchen

So,

Area of kitchen:

$A = 12 * 7\\ = 84\ square\ feet$

The area is 84 square feet which means 84 one square foot tiles are needed to completely cover the floor of kitchen.

As Peterson already has 45 tiles, so the more tiles she will need is:

$84-45 = 39\ tiles$

Hence,

Peterson will need 39 more tiles to completely cover the kitchen floor

Find the volume of this square based pyramid. 10 cm 8 cm 8 cm V = [?] cm3

oksano4ka [1.4K]

Answer:

213.3

Step-by-step explanation:

The volume of a pyramid is 1/3 base times height.

Using this formula, our square base is 8*8, or 64 square units.

Multiplying that by the height, 10. We get 64*10, 640.

Finally dividing by 3, we have 213.3333333333...

Rounding that to the nearest tenth, 213.3.

$14.30 - 1.95 = 12.35$
Maria spend $12.35 on songs, to find out how many songs, you divide that by $.95
$12.35 \div .95 = 13$

Which expression represents the number of feet that are in x yards?

AleksandrR [38]

we know that

$1\ yard=3\ feet$

Let

y-------> the number of feet that are in x yards

by proportion

Find the value of y

$\frac{3}{1} \frac{feet}{yard}=\frac{y}{x} \frac{feet}{yards} \\ \\y=3x\ feet$

therefore

the answer is the option C

$3x$

Correct Inputs :-

In ΔABC right angled at A, D and E are points on BC, C such that BD = CD and AD ⊥ BC

$\underline{\underline{\large\bf{Solution:-}}}\\$

$\longrightarrow$ Let us know about definition of altitude first. The altitude of a triangle is the perpendicular line segment drawn from the vertex to the opposite side of the triangle.

$\leadsto$ Median is the line segment from a vertex to the midpoint of the opposite side.

Let us Check all options one by one

CD is line segment which starts from vertex C but don't falls on opposite side AB thus it is not an altitude.❌

BA is line segment which starts from vertex B and falls perpendicularly on opposite sides AC and is thus an altitude.✔️

AD is line segment which starts from vertex A and falls perpendicularly on opposite side BC and is thus an altitude.✔️

AE is a line segment which starts from vertex A but doesn't falls perpendicularly on opposite side BC and is thus not an altitude.❌

AD falls on BC with D as mid point because BD = CD and is thus a median. ✔️
