Answer: The ratio of Mike and Sam Heights are S:M=5:4
Step-by-step explanation:
Ravi is 3/4 as tall as Sam.
Consider the equation is 3/4 *R=S
Mike is 5/3 as tall as Ravi.
Then, the equation is 5/3 *M=R
Solve the two equation to find ratio of mikes and sam height.
3/4*R=S Eq(1)
Rearranging eq (1) for R
R=4/3 *S Eq(3) made from eQ (1)
R=5/3*M Eq(2)
Comparing Eq 2 &3 equations
4/3*S=5/3*M
S/M=(5/3)*(3/4)
S/M=5/4

Find the area of the semicircle. Round to the nearest hundredth if necessary.
9514 1404 393
Answer:
8π m² ≈ 25.13 m²
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr²
The area of a semicircle is half that. Also, the radius (r) is half the diameter. So. the area of this semicircle is ...
A = (1/2)π(4 m)² = 8π m² ≈ 25.13 m²

Comment on pi
If you use the 3-digit value 3.14 for pi to compute this 4-digit result, you will get 25.12.
A factory received a shipment of 11 hammers, and the vendor who sold the items knows there are 2 hammers in the shipment that are defective. Before the receiving foreman accepts the delivery, he samples the shipment, and if too many of the hammers in the sample are defective, he will refuse the shipment. Give answer as a decimal to three decimal places
Question:
If a sample of 2 hammer is selected
(a) find the probability that all in the sample are defective.
(b) find the probability that none in the sample are defective.
Answer:
a [tex]Pr = \frac{2}{110}[/tex]
b [tex]Pr = \frac{72}{110}[/tex]
Step-by-step explanation:
Given
[tex]n = 11[/tex] --- hammers
[tex]r = 2[/tex] --- selection
This will be treated as selection without replacement. So, 1 will be subtracted from subsequent probabilities
Solving (a): Probability that both selection are defective.
For two selections, the probability that all are defective is:
[tex]Pr = P(D) * P(D)[/tex]
[tex]Pr = \frac{2}{11} * \frac{2-1}{11-1}[/tex]
[tex]Pr = \frac{2}{11} * \frac{1}{10}[/tex]
[tex]Pr = \frac{2}{110}[/tex]
Solving (b): Probability that none are defective.
The probability that a selection is not defective is:
[tex]P(D') = \frac{9}{11}[/tex]
For two selections, the probability that all are not defective is:
[tex]Pr = P(D') * P(D')[/tex]
[tex]Pr = \frac{9}{11} * \frac{9-1}{11-1}[/tex]
[tex]Pr = \frac{9}{11} * \frac{8}{10}[/tex]
[tex]Pr = \frac{72}{110}[/tex]

I need answers
Answer:
a line going straight up and down at x = -4
Step-by-step explanation:
Answer:
x = -4 describes a perfectly vertical line that crosses through the point (-4, x), where x is any real number. So to draw it, simply measure the point (-4, 0), and draw a vertical line that crosses through it.
. A farm stand displays 3 baskets with 12 peaches in each basket and 2 baskets with 15 plums in each basket. A customer buys 8 pieces of fruit. Which equation shows how to find the number of peaches and plums, p, in the basket? *
1 point
3 + 12 x 2 + 15 - 8 = p
12 -3 + 15 - 2 x 8 = p
3 x 12 + 2 x 15 + 8 = p

C)The hydrophilic heads point into and out of the cell, while the hydrophobic tails form a layer between the heads.
D)The hydrophilic tails point into and out of the cell, while the hydrophobic heads form a layer between the tails.
Fast plz.
Answer:
Option D
Step-by-step explanation:
The phospholipid bilayer that makes up a cell membrane comprises of two essential parts a) Water loving part or the hydrophilic part which points outwards towards cytoplasm and b) Water hating part of hydrophobic part which point towards the interior of the membrane, and is sandwiched between two layers of hydrophilic heads
Hence, option D is correct

Find each measure.
K
X=
6x
M
L
Answer:
x = 15
z = 25
Step-by-step explanation:
In [tex] \odot\: O, \: \angle MLK [/tex] is inscribed in a semicircle.
[tex] \therefore m\angle MLK =90\degree [/tex]
[tex] \therefore 6x\degree =90\degree [/tex]
[tex] \therefore 6x =90[/tex]
[tex] \therefore x =\frac{90}{6}[/tex]
[tex] \therefore x =15[/tex]
In [tex] \odot\: A, \: \angle PRQ[/tex] is inscribed in a semicircle.
[tex] \therefore m\angle PRQ =90\degree [/tex]
[tex] \therefore (4z-10)\degree =90\degree [/tex]
[tex] \therefore 4z-10 =90[/tex]
[tex] \therefore 4z =100[/tex]
[tex] \therefore z =\frac{100}{4}[/tex]
[tex] \therefore z =25[/tex]
