I'm not 100% sure but I think it's 10:10 because of the Spoons - 10:30.

Answer:

<h2>3000 pcs</h2>

Step-by-step explanation:

given:

the Length, breadth and height of a wall is 5m,30cm and 3 m

find:

how many bricks of dimensions 20cm ×10 cm× 7.5 cm are required to build the wall

solution:

vol of the wall = 5 x 3 x 0.30= 4.5 m³

vol per brick = 0.20 x 0.10 x 0.075 = 0.0015 m³

number of bricks = <u> wall volume </u>

vol. per brick

= 4.5 / 0.0015

= 3000 pcs of bricks required

The concentration, in parts per million, of a type of antibiotic in a human's bloodstream after h hours can be modeled by the po

saveliy_v [14]

Answer:

$C(3)=17.69\ ppm$

Step-by-step explanation:

Given:

Given polynomial function is.

$C(h)=-0.09h^{2} +3.5h+8$

Hours $h=3$

We need to find the concentration of the antibiotic after 3 hours.

Solution:

Rewrite the given polynomial function as.

$C(h)=-0.09h^{2} +3.5h+8$

Substitute $h=3$ in given polynomial function.

$C(3)=-0.09(3)^{2} +3.5\times 3+8$

$C(3)=-0.09\times 9+10.5+8$

$C(3)=-0.81+10.5+8$

$C(3)=-0.81+18.5$

$C(3)=17.69\ ppm$

Therefore, the concentration of the antibiotic after 3 hours $C(3)=17.69\ ppm$ .

In a right triangle, the length of the hypotenuse is 20 inches and length of one leg is 15 inches. What is the length of the roo

Gekata [30.6K]

We can solve this problem using the Pythagorean Theorem. The Pythagorean Theorem states, that with hypotenuse c, and legs a and b, a² +b² = c², and since this is a right triangle, that principle is true here. In this problem, we have the length of the hypotenuse and leg a. So, we can insert the values of the variables and then simplify to find out the length of b. 15²+b²=20²b²=400-225b²=175b=√175

The ratio of boys to girls is 14:17 if there are 186 people altogether how many bows are in the camp

Serggg [28]

<span>boys = 14x
</span><span>girls = 17x

14x + 17x = 186
31x = 186
x = 186/31
x = 6

</span>boys = 14x = 14 * 6 = 84

Suppose you flip a coin twice and count the number of heads you observe. Youthen roll a 4 sided die (like a 6 sided die, but onl

vladimir2022 [97]

Answer:

Sample space=S={HH1,HT1,TH1,HH2,HT2,TH2,HH3,HT3,TH3,HH4,HT4,TH4}

Step-by-step explanation:

The sample space for Y can be made as under

Coin is tossed two times={HH,HT,TH,TT}

4-sided die is rolled={1,2,3,4}

Coin is tossed two times and 4-sided die is rolled

={HH1,HT1,TH1,TT1,HH2,HT2,TH2,TT2,HH3,HT3,TH3,TT3,HH4,HT4,TH4,TT4}

Y be the random variable that the number of heads observed multiply by die roll number so, the sample space for Y would be

Sample space=S={HH1,HT1,TH1,HH2,HT2,TH2,HH3,HT3,TH3,HH4,HT4,TH4}
