Answer 1

Answer:

Answer with explanation:

The given equation is:

$x^2=25\n\nx^2=(\pm 5)^2\n\n x=\pm 5$

On the number line, mark circles on 5 and -5 , respectively.

Option B:

A number line is shown from negative 25 to 0 to positive 25. There are increments of 5 on the number line, and all these increments are labeled. A dot is shown on positive 5, another dot is shown on negative 5 and they are labeled as p and q, respectively.

Answer 2

Triangle ABC is similar to triangle QRS by the AA Similarity Postulate.Also, m∠A = 45° and m∠S = 75°.

What is m∠B?

_________ °

Answers

Answer:

Measure of ∠B is 60°

Step-by-step explanation:

Given triangle ABC is similar to triangle QRS.

m∠A = 45° and m∠S = 75°

we have to find the measure of ∠B.

As triangles are similar then corresponding angles are congruent.

⇒ ∠A≅∠Q, ∠B≅∠R, ∠C≅∠S

hence, m∠C=m∠S=75°

By angle sum property

m∠A+m∠B+m∠C=180°

⇒ 45°+m∠B+75°=180°

⇒ m∠B+120°=180°

⇒ m∠B=60°

hence, measure of ∠B is 60°

Angle B is 60 degrees

5) What is the value of n in the picture?3n
n 14
A) 19
B) 33
C) 57
D) 41.5

Answers

ok. because those two angles are sumplimentary, (they equal 180 degrees) we can set up an equations.
3n+n+14=180

then isolate the variable
4n+14=180
-14 -14
4n=166

then divide to undo the multiplication

4n=166
--- ----
4 4

n=41.5

that's super wrong .the answer cannot be 41.5 because if n=41.5 then 41.5 ×4 =166 +90 +14 =270 and that's wrong because in the diameter need have 180 not 270 so is 19×4+90+14=180 answer = 19

The product of 7/16, 4/3, and 1/2 isa. 7/12.
b. 7/24.
c. 21/32.
d. 2 13/48.

Answers

If you would like to know how much is the product of 7/16,4/3, and 1/2, you can calculate this using the following steps:

7/16 * 4/3 * 1/2 = 7/24

The correct result would be b. 7/24.

$(7)/(16) * (4)/(3) * (1)/(2) = (7* 4* 1)/(16* 3* 2)=(7* 4)/(4* 4* 3* 2)=(7)/(4* 3* 2)\n\n =(7)/(12*2) =\boxed{\bf{(7)/(24)}}$

Your answer is B. 7/24.

56 is 69% of what number? Round your answer to the nearest hundredth if necessary.Incorrect answer:124

Answers

Answer:

Approximately 81.159

Step-by-step explanation:

First, set up the equation

56 = (0.69)(x)

^ is 69% of a number

Divide each side by 0.69 to simplify

56 / 0.69 = x

x ≈ 81.159420...
