At the beginning of June, Max and Sean start saving money for the fair, which occurs 10 weeks later. Sean
starts out with $20 and saves just $2 per week. Max starts out with no money, but saves 5 dollars per week.
After how many weeks will Max have more money saved than Sean?
Answer:
Step-by-step explanation:
sean has 20 +2 : 2 x 7 = 14 + 20 = 34
max has 0 + 5: 5 x 7 = 35
so after 7 week max will have more money

A principal wants to know if students at a particular high school are in favor of a new dress code at their school. The principal is not able to ask the opinion of every student at the school, so she needs to select an appropriate sample of the students to represent the high school. Select which sample of students the principal should choose. A Students randomly selected from a list of all students at the school. B Students sitting at randomly selected tables in the library. Students she selects from the hallway between classes. Students selected by the teachers.
Answer:
student randomly selected from a list of all students at the school
please help me if you can!
Answer:
A is 55°
Step-by-step explanation:
To solve this, you need to remember that the sum of the angles inside a triangle is equal to 180 degrees.
Also, noting that this is an isosceles triangle. That means that a and b are equal. With that in mind, we can simply say:
a + b + c = 180
a ≡ b ∴ 2b + c = 180
2(4x + 31)° + (2x + 58)° = 180°
8x° + 62° + 2x° + 58° = 180°
Let's just stop right here, and note that normally you can treat symbols of measurements just like variables. We've done the same here, applying the distributive property with the ° symbol. Note though that it's currently part of every single term, so I'm going to factor it out:
(8x° + 62° + 2x° + 58°) / 1° = 180° / 1°
8x + 62 + 2x + 58 = 180
10x + 120 = 180
10x = 60
x = 6
Again noting that A and B are identical due to this being an Isosceles triangle, we can say:
A = (4x + 31)°
A = 24° + 31°
A = 55°
We can also check our answer. The sum of the angles should be 180, and two of those angles should be 55. That means that angle C should be 180 - 2 * 55, or 180 - 110 = 70. Let's test it:
70 = 2x + 58
70 = 12 + 58
70 = 70
So we know that our answer is correct.
HELPPPPP PLS ILL GOVE THE BRAINLIEST ANSWER !! just help asap !!
answer is 4√2
because, using pythagoras theorem
x² = 4² + 4²
x² = 16 + 16
x² = 32
x = √32
x = √(16 × 2)
x = √16 × √2
x = 4 × √2
x = 4√2
Consider triangles CBD and BDE and answer the questions that follows
2.1 Which side is common in both triangles?
2.2 What can be concluded about the heights of A CBD
and A BDE? Give a reason for your answer.
2.31 Using your answers from 2.1 und 2.2 above complete
the following statements:
2.3.1 Area of A CBD
2.3.2 Area of ABDE
2.4 What can be concluded about the area of A CBD and
ABDE?
Answer:
Step-by-step explanation:
∠ABD ≅ ∠BDE..... (given).... (1)
m∠ABD + m∠CBD = 180°... (straight line ∠'s)... (2)
From equations (1) & (2)
m∠BDE + m∠CBD = 180°....(3)
m∠BDE + m∠CDB = 180°... (straight line ∠'s)... (4)
From equations (3) & (4)
m∠BDE + m∠CBD = m∠BDE + m∠CDB
m∠CBD ≅ m∠CDB.. (Proved)
Good morning can somebody help me out the answer choice are
A.56.4 degrees
B.40.0 degrees
C. 13.3 degrees
D. 33.6 degrees
Answer:
Option D
Step-by-step explanation:
Measure of adjacent side = 20
Measure of Hypotenuse = 24
Since, measures of adjacent side and Hypotenuse have been given in the question, cosine ratio will be applied to find the measure of angle x.
cos(x) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(x) = [tex]\frac{20}{24}[/tex]
x = [tex]\text{cos}^{-1}(0.833)[/tex]
= 33.55°
≈ 33.6°
Option D is the answer.

Draw a line from point A to point C.
ΔACD is a right triangle.
Solve for ∠CAD:
sin CAD = 3/5 = 0.6000
∠CAD = 36.87°
arc CD = 2 x 36.87° = 73.74°
arc BC = arc CD = 73.74°
arc DB = 147.48°
∠BAD = 1/2 (147.48°) = 73.74°
draw a line from point D to point B
ΔBAD is a right triangle.
cos 73.74° = AB/5
AB = 1.4

Nancy and Evan are each writing a 6-page essay. Nancy completed 4/6 of her essay in the morning and 2/6 of her essay in the afternoon. Evan completed 3/6 of his essay before school and 2/6 of his essay after school. Nancy says that she completed more of her essay than Evan. Evan says that he completed more of his essay than Nancy. Who is correct?
Answer:Nancy completed more of the essay.
Step-by-step explanation:4/6 + 2/6 = 6/6 = Nancy
3/6 + 2/6 = 5/6 = Evan
Therefore Nancy did more of the essay.
