Select the perfect square.
23 x 23
924 x 429
18 x 19

Answers

Answer 1
23x23 because the sides will be even
Answer 2

Answer:

23 × 23

Reasoning:

A prefect square is a number times itself

The product of the perfect square can therefore be a sqaure root

23 × 23= 529

Then if we square root 529 it would always be a whole number (23)

Answer:

1) a. 15ft

b. 6ft

c. 30ft

2) a. 16m

b. 12m

c. 192m

answer for the 1st question:

1) length is 15 ft

2) width is 6ft

3) the area is 90 ft²

step-by-step explanation:

ok so we know that the plan is 2 in/6 ft

step 1-

we need to find the length of the terrace, and we know that the length of the terrace in the plan is 5 in

so by proportion- we'll need to find the length of the 'actual' terrace

2 in/ 6 ft= 5 in/ x ft

x=6*5/2

x=15 ft (we now have the length)

step 2-

now that we know the length, we need to find the width

the length of the terrace in the plan is 2 in

and by proportion- we'll find the 'actual' width of the terrace

2 in/6 ft=2 in/ x ft

x=6*2/2

x=6 ft

and now we'll find the area of the terrace (step 3)-

the formula for the area of a rectangle is a=lw or area=length*width

now we just fill the variables in with what we know-

so we know that 15 ft is the length and that 6 ft is the width-

15*6=90 ft²

In the earlier Lesson Activity, you found the sizes of mesoplankton and jellyfish. In this activity, you’ll determine the most appropriate units for measuring the sizes of mesoplankton and jellyfish.

Part B
You also found the size of a jellyfish to be 2 meters. Do you think that meters are the most appropriate unit to represent the size of a jellyfish? If not, what do you think would be the most appropriate unit? Write the size of the jellyfish in the most appropriate unit.

Answers

Answer:

We did not read the lesson so we dont kown

I can answer the seocnd question i think no because as meters may be to small for some jellyfish as they come in diffrence sizes so i think millimeter are the prefect size.

This is the same as therate of change from 8 hours to 12 hours,  or 3 cents per hour, and from 12 hours to 24 hours,  or 3 cents per hour. So, the rate of change is a constant 3¢ per hour.

The area of a circle is 153.86 square meters. What is the diameter of the circle? Use 3.14 for π. show you work.

Answers

the diameter is 49

you take 153.86 and divide it by 3.14

Answer:

14 meters²

Step-by-step explanation:

Since the formula to find the diameter is [tex]d=2r[/tex], we need to first find the radius, which can be [tex]r=\frac{\sqrt{A\pi}}{\pi}[/tex] if we take the formula for the area of a circle and isolate the radius. After simplifying [tex]r=\frac{\sqrt{153.86\pi}}{\pi}[/tex] to 7 and multiplying that by 2, we get the circle's diameter of 14 meters. Hope this helps!

Given: circle k(O), diameter US, measure of arc RU=50, measure of arc UT=30
Find: measure of angle RUS and measure of angle UST

Answers

Answer:

angle RUS = 65 degrees

angle STU = 90 degrees

Step-by-step explanation:

(a) find angle RUS

Given arc RU = 50 degrees, so angle RSU = 50/2 = 25 degrees

Since US is the diameter,

angle URS is a right-angle.

Consider triangle RUS,

sum of angles of a triangle = 25+90+RUS = 180  

solve for

RUS = 180 - 25 - 90 = 65 degrees.

(b) Find STU

All diameters span a right angle at the circumference,

since we're given US is a diameter, this means that

angle STU is a right angle.

The measure of the ∠RUS is 65°, while the measure of ∠UST is 15°.

What is Thales theorem?

The angle ABC is a right angle if A, B, and C are different points on a circle where the line AC is a diameter, according to Thales' theorem.

We know that when an angle is made by the diameter of a circle at its circumference, then the measure of that angle is 90°.

In ΔUST,

The angle made by the diameter is ∠UST, therefore, the measure of this angle will be 90°. Since the measure of the arcRU=50°, therefore,

arcRU = ∠ROU = 50°, Also,

[tex]\angle RSU=\dfrac{\angle ROU}2 =\dfrac{50^o}2 = 25^o[/tex]

Now, the sum of the angles of a triangle is 180°.

∠R+∠U+∠S=180°

90°+∠RUS+25°=180°

∠RUS = 65°

In ΔRUS,

The angle made by the diameter is ∠URS, therefore, the measure of this angle will be 90°. Since the measure of the arcUT=30°, therefore,

arcUT = ∠UOT = 30°, Also,

[tex]\angle UST=\dfrac{\angle UOT}2 =\dfrac{30^o}2 = 15^o[/tex]

Thus, the measure of the ∠RUS is 65°, while the measure of ∠UST is 15°.
