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)

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°.

pls help

Answers

Answer:

They did not leave the correct amount. They left around a 22% tip

Step-by-step explanation:

15% = 0.15

68.25(0.15)

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.

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

SOLUTION:  Analyze the table. The rate of change from 5 hours to 8 hours is  or 3 cents per hour. 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.

Answers

She would weigh 105 pounds on Venus.
120 divided into 8 groups will equal 15.
Then subtract 15 from 120 to get 105 pounds.
Now there are 7 groups of 15 when she is on Venus and 8 groups when she is on Earth. That is where the ratio is used.
