Answer 1

Answer:

the correct answer is <D is 72 degrees

Step-by-step explanation:

x + 36=180°

x= 180-36

x=144°

To find angle d divide your answer by 2

therefore angle d is 72°

Answer 2

Answer:

It is fuzzy but it looks like ∠A is 35°. If that's correct, then:

∠D = 35°

(if ∠A is 36°, then ∠D is 36°)

Step-by-step explanation:

It is indicated that ∠C and ∠F are 90°.

It is also indicated that ∠B and ∠E are equal.

Therefore, ∠A = ∠D

Answers

Correct question:

a sequence U1, U2,U3...... is defined by the relation [tex]U_{n +1} = 2U_n +5[/tex]. if U1 =2, find U2 and U3

Answer:

U2 = 9

U3 = 23

Step-by-step explanation:

Given sequence;

[tex]U_{n +1} = 2U_n +5[/tex]

U1 = 2

U2 = ?

[tex]U_{n +1} = 2U_n +5\\\\U_2 = 2(U_1) + 5\\\\U_2 = 2(2) + 5\\\\U_2 = 4 + 5\\\\U_2 = 9[/tex]

Solving for U3;

[tex]U_3 = 2(U_2) + 5\\\\U_3 = 2(9) + 5\\\\U_3 = 18 + 5\\\\U_3 = 23[/tex]

An access ramp to a building is 3.7 m long. The distance from beginning of the ramp to the base of the building is 3.5 m. How tall is the ramp?

Answers

Answer: 1.2 m

Step-by-step explanation:

Given

The length of the ramp to the building is 3.7 m

Distance from the beginning of the ramp to the base of the building is 3.5 m.

Suppose h is the height of the ramp

from the figure, we can write

[tex]\Rightarrow 3.7^2=3.5^2+h^2\\\Rightarrow 13.69-12.25=h^2\\\Rightarrow h^2=1.44\\\Rightarrow h=1.2\ m[/tex]

So, the height of the ramp is 1.2 m

Just note that -5 1/2+6 3/4=1 1/4.

Then, we do 1 1/4+(-4 1/4)

This is just -3.

First you can add the whole numbers 6-5-4 i belive that says and then add the freactions by making the denominator the same for each so instead of 1/2 it would be 2/4 and then add the fractions and add the answer to the whole numbers. It should be -3!!!

An isosceles right triangle is inscribed in a circle. The hypotenuse of the triangle is the diameter of the circle. Write a function f in terms of x that represents the area of the shaded region. Leave your answer in terms of π.

Answers

9514 1404 393

Answer:

f(x) = (π-2)x^2/4

Step-by-step explanation:

The area of the triangle is ...

A = 1/2(x)(x) = (1/2)x^2

The hypotenuse of the triangle is x√2, so the radius of the circle is x/√2. That means the area of the semicircle is ...

A = 1/2πr^2 = (π/2)(x/√2)^2 = (π/4)x^2

The shaded area is the difference between the semicircle area and the triangle area.

f(x) = (π/4)x^2 -(1/2)x^2

f(x) = (π-2)x^2/4

Your friend has n pennies. You have 29 pennies. You and your friend have a total of 40 pennies. Which equation could be used to find n?

Answers

Answer:

40-29=n

Step-by-step explanation:

You have 29 in total yall have 40

so to find ur friends we subtract

Answer:

Step-by-step explanation:

your pennies + your friends pennies = the total number of pennies between you two

so the equation would be :

29 + n = 40

(im not sure if you wanted it solved for n but here is the solution just in case)

29 + n = 40

n = 40 - 29

n = 11

Quarter pounder has -580 calories and the Whooper has

1589 calories

Step-by-step explanation:

Let x represent quarter pounders and y represent the Whoppers.

2 QP and 3 Whoppers provide 3607 calories and one of each provide 1009. so let set up the system

[tex]2x + 3y = 3607[/tex]

[tex]x + y = 1009[/tex]

Apply subsitution method

[tex]y = 1009 - x[/tex]

[tex]2x + 3(1009 - x) = 3607[/tex]

[tex]2x + 3027 - 3x = 3607[/tex]

[tex] - x + 3027 = 3607[/tex]

[tex] - x = 580[/tex]

[tex]x = - 580[/tex]

Plug the system back into one of the equations and we get

Zoe says an equilateral triangle is always an acute triangle, but an acute triangle is never an equilateral triangle. Which statement explains whether Zoe is correct or not?

Select one:
a. Zoe is not correct because equilateral triangles are acute triangles with three sides of equal length. Acute triangles can sometimes be equilateral triangles.

b. Zoe is not correct because equilateral triangles have three acute angles. Acute triangles have three acute angles, so acute triangles are always equilateral triangles.

c. Zoe is correct because equilateral triangles have three sides of equal length, and acute triangles have three sides of different lengths.

d. Zoe is correct because equilateral triangles have three acute angles. Acute triangles have one acute angle, so an acute triangle cannot be an equilateral triangle.

Answers

Answer:

Step-by-step explanation:

Zoe is correct because equilateral triangles have three acute angles. Acute triangles have one acute angle, so an acute triangle cannot be an equilateral triangle. Therefore, option D is the correct answer.

What is an acute angle?

An acute angle is an angle that is less than 90°, and these angles can be measured using a protractor.

Triangles can be classified on the basis of angles and sides. An acute triangle is one that is classified on the basis of the measurement of angles. If all the interior angles of a triangle are less than 90°, then the triangle is said to be an acute triangle.

In equilateral triangle all three angles are equal, that is 60°.

Therefore, option D is the correct answer.
