Answer:

Step-by-step explanation:

Perimeter of Square = 40 cm

4*side = 40

side = 40/4

side = 10 cm

Area of shaded region= Area of square - [Area of triangle 1 + Area of triangle 2]

$=[side*side]-[\frac{1}{2}*b*h+\frac{1}{2}*b*h]\\\\=[10*10]-[\frac{1}2}*3*10+\frac{1}{2}*10*6]\\\\=100-[3*5+5*6]\\\\=100-[15+30]\\\\=100-45\\\\=55cm^{2}\\$

Percentage = (55/100)*100=55%

Answer: θ = 162°

Step-by-step explanation:

C = 2πR

therefore R = C/2π = 10/2π = 5/π units

9/2 = Rθ

θ = (9/2) / R = (9/2) / 5/π = (9/2)(π/5) = 9π/10 radians

9π/10 rad(180°/π rad) = 162°

Match the graph of the function with the function rule

irga5000 [103]

As seen from the graph, the y intercept is (0,0.5)

plugging this value in each equation:

y=1*4^x

plugging x as 0 and y as 0.5

lhs≠rhs

$y=\frac{1}{4} *4^{x}$

plugging x as 0 and y as 0.5

lhs≠rhs

$y=\frac{1}{2} * 4^{x}$

plugging x as 0 and y as 0.5

lhs = rhs

so answer is $y=\frac{1}{2} * 4^{x}$

A painter uses 2 tubes of blue paint for every 6 tubes of white paint to paint a mural. At that rate ,How many tubes of blue pai

Jlenok [28]

Answer:

5 tubes of blue paint are used for 15 tubes of white paint.

Step-by-step explanation:

Given:

To paint a mural painter uses 2 tubes of blue paint for every 6 tubes of white paint

Hence,

6 tubes of white paint = 2 tubes of blue paint

Now we need to find number of blue paint tubes used for 15 tubes of white paint.

6 tubes of white paint = 2 tubes of blue paint

15 tubes of white paint = number of blue paint tubes used for 15 tubes of white paint

Hence we will used unitary method to find the same;

Number of blue paint tubes used = $\frac{15\times 2}{6} = \frac{30}{6}=5$

Hence 5 tubes of blue paint are used for 15 tubes of white paint.

Joey had 3 cakes to sell at the school bake sale. 10 people wanted to buy the 3 cakes, so he decided to divide them up equally.

Lilit [14]

So we start off with the division and you do 10/3 which gets you 3.33333333333 which cannot be an answer but decimals can turn into fractions so your answer would be C
hope this helped you out!

Riya is applying mulch to her garden. she applies it at a rate of 250 , 000 cm 3 250,000 cm 3 250, comma, 000, start text, space

Tatiana [17]

The rate in

$\frac{ {m}^{3} }{ {m}^{2} } \: is \:0.25\frac{ {m}^{3} }{ {m}^{2} }$

<h3>How to find rate is riya applying mulch in m^3/m^2 ?</h3>

given that riya applies it at a rate of 250,000 cm^3 of mulch for every m^2 of garden space.

we already know that 1m = 100cm.

so, each side of this cube is 100cm in length.

so, $100 \times 100 \times 100 \: {cm}^{3} \: in \: {m}^{3}$

To find what is the volume in cubic metres.

$\frac{250000}{10000000} = \frac{1}{4} = 0.25 \frac{ {m}^{3} }{ { m}^{2} }$

so, the rate is $0.25 \frac{ {m}^{3} }{ {m}^{2} }$
