riadik2000 [5.3K]

Answer:

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

triangles
equation
PEMDAS

<h3>given:</h3>

$M\angle T=2x+2$
$M\angle R=3x+1$

<h3>tips and formulas:</h3>

this is an isosceles triangle since two sides are equal therefore $\angle T=\angle S$
a triangle contains 180°

<h3>let's solve:</h3>

according to the question

2x+2+2x+2+3x+1=180

solve:

collect like terms:7x+5=180
substract 5 from both sides:=>7x+5-5=180-5=>7x=175
divide both sides by 7: =>7x/7=175/7

x=25

given:

M∠R=3x+1

substitute the value of x

3×25+1

75+1

Find the mean, median, and mode of the listed numbers.

-BARSIC- [3]

Step-by-step explanation:

mean: (3 + 2 + 7 + 7 + 3 + 8 + 5 + 7 + 2 +8)/10 = 5.2

median: 2, 2, 3, 3, 5, 7, 7, 7, 8, 8 hence median is (5 + 7) / 2 = 6

mode: 7

Topic: mean median mode

About how many times larger than the diameter of a red blood cell is the diameter of a grain of sand? Write your answer using a

Alchen [17]

Answer:

$0.29\cdot10^3$

Step-by-step explanation:

Red blood cell: $8.4\cdot 10^{-6}$

Grain of sand: $2.4\cdot 10^{-3}$

The "how many times larger" part can be figured out by forming a ratio between the two diameters above:

$\frac{2.4\cdot 10^{-3}}{8.4\cdot 10^{-6}} = \frac{2.4}{8.4}\cdot\frac{10^{-3}}{10^{-6}}\approx 0.29\cdot 10^{-3-(-6)}=0.29\cdot10^3$

Note that dividing the powers of ten corresponds to subtracting the denominator power from the numerator power of 10.
