Answer:
28 m, 112 m
Step-by-step explanation:
x = length of short piece
4x = length of long piece
x + 4x = 140
5x = 140
x = 140/5 = 28
4x = 4(28) = 112

A swimming pool is 8 meters long, 8 meters wide, and 8 meters deep. The water
resistant paint needed for the pool costs $6 per square meter.
Part A: What is the surface area of the pool that needs to be painted? (Remember there is not a
top to the pool)
Part B: Based on the surface area you calculated, what is the total cost of the paint needed to paint
purchased?
Answer:
A. 320 sq. ft.
B. $1920
Step-by-step explanation:
You need to find 5 sides. They are all 8*8. 64*5 is 320. Now, you multiply that by 6 to get $1920

Write a quadratic function in vertex form whose graph has the vertex (-2, - 13) and passes
through the point (-6,3).
Answer:
f(x) = ⁵/₈(x+2)² - 13Step-by-step explanation:
Vertex form of the equation of a quadratic function with vertex (h,k):
f(x) = a(x - h)² + k
To find a we need to put the point and the vertex into this equation:
3 = a(-6 + 2)² - 13
10 = a(-4)²
16a = 10
a = ⁵/₈
Therefore, vertex form of the quadratic function:
f(x) = ⁵/₈(x+2)² - 13

By solving the expression (3x2 +4x − 15) ÷ (x +3) the quotient is 3x-5 and r=0
What do you meant by quotient?When solving a division problem, the quotient is obtained by dividing the dividend by the divisor.
Mathematically, we denote the outcome of this division by separating the quotient and remainder with a capital R. (see below). The entire number that results from simplifying a fraction is known as the quotient.
We can do it by long division method the required quotient is 3x-5 and r=0
not 3x-1 , r=1
multiply the divisor with 3x we will get 3x²+9x to cancel out the first term of dividend.
Now after solving we will get -5x -15
Now, multiply the divisor by -5 we will get -5x-15 which will cancel the entire dividend.
So that the quotient is 3x-5 and r=0

A sequence has a rule to subtract 3/4 from the previous term. Create a sequence using this rule with at least 5 rational numbers.
1, 1/4, -1/2, -5/4, -2
Step-by-step explanation:
Let the first term of the sequence be a;
Since the sequence has a rule to subtract 3/4 from the previous term;
the second term will be a - 3/4
the third term will be (a - 3/4) - 3/4
=> a - 6/4
=> a - 3/2
the fourth term will be (a - 3/2) - 3/4
=> a - 9/4
the fifth term will be (a - 9/4) - 3/4
=> a - 12/4
=> a - 3
We can then create a hypothetical series by setting a = 1.
The first term => a = 1
The second term => a - 3/4 = 1 - 3/4 = 1/4
The third term => a - 3/2 = 1 - 3/2 = -1/2
The fourth term => a - 9/4 = 1 - 9/4 = -5/4
The fifth term => a - 3 = 1 - 3 = -2
The generated sequence is therefore:
1, 1/4, -1/2, -5/4, -2
Note: The numbers in the sequence are rational numbers since they all have a non-zero denominator.

Step-by-step explanation:
They both satisfy the equation as 5+2=7 and 5-2=3
Hope this helps!
Here we have been given with two equations and we have to calculate the value of a and b by solving them simultaneously.
a + b = 7 (Equation No 1)a - b = 3 (Equation No 2)★ From Equation No 2 :
>> a - b = 3
>> a = 3 + b
★ In Equation No 1 :
Substituting here the value of a which we got above as (3 + b).
>> a + b = 7
>> 3 + b + b = 7
>> 3 + 2b = 7
>> 2b = 7 - 3
>> 2b = 4
>> b = 4 / 2
>> b = 2
★ Finding out value of a :
>> a = 3 + b
>> a = 3 + 2
>> a = 5 [tex] \: [/tex]

Answer:
what is this
Step-by-step explanation:
A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
A triangle ABC is shown. The base of the triangle extends into a straight line. The angle formed between this straight line and the edge of the triangle is marked as p. The angle adjacent to p is marked as o, and the other two angles inside the triangle are marked as m and n.
Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle)
Step 2: m∠p − m∠o = 90 degrees (alternate interior angles)
Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p
Step 4: So, m∠m + m∠n = m∠p
In which step did the student first make a mistake and how can it be corrected? (4 points)
a
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (corresponding angles)
b
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
c
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
d
Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles)
Answer:
C. Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step-by-step explanation:
The student first made a mistake in step 2. In order to check if the sum of the measures of the two remote interior angles of a triangle is equal to the measure of the exterior angle, it is necessary to use the property of alternate exterior angles. Alternate exterior angles are angles that are on opposite sides of the transversal and between the same parallel lines, so they are congruent. The measure of alternate exterior angles is always equal to 180 degree. Therefore, the correct statement in step 2 is that m∠o + m∠p = 180 degrees (alternate exterior angles)

Answer:
a = 35, b = 40, c = 17.5
Step-by-step explanation:
The sum of the 3 arcs on the semicircle above the diameter = 180° , that is
65 + 80 + a = 180
145 + a = 180 ( subtract 145 from both sides )
a = 35
The inscribed angles b and c are half the measures of their intercepted arcs
b = [tex]\frac{1}{2}[/tex] × 80 = 40
c = [tex]\frac{1}{2}[/tex] × 35 = 17.5
Papa Bear ate a quarter of the pie. Mama Bear ate a third of what was left. Baby Bear ate half of what was left. How much of the pie was left for Goldilocks
Mama bear only ate (1/4) of the pie, leaving Goldilocks with the remaining (1/8) fraction.
Which fraction is it?The fraction is expressed in the form a/b, where an is referred to as the numerator and b is referred to as the denominator. The fraction is a rational number that only divides two integers.
Let the pie's largest portion be a.
Half of the pie was consumed by Papa Bear.
Papa Bear then consumed = (1/2)a.
Rest of the pie is equal to a- (1/2).
a= (1/2)a
Mama bear consumed (half) of the remaining pie.
Mother bear consumed (1/2)(1/2).
pie portion a= (1/4) pie portion after mom bear has eaten = (1/2)
a- (1/4)a= (1/4)a
Baby bear afterwards consumed (half) of the remaining pie.
Baby bear ate (1/2)(1/4), thus. After the young bear has finished eating, the remaining pie is equal to (1/4) a- (1/8)a= (1/8)
The remainder of the component was given to GoldLiocks.
As a result, mom bear only ate (1/4) of the pie, leaving Goldilocks with the remaining (1/8) portion.
The complete question is Papa Bear ate 1/2 of a pie. Mama Benr ate 1/2 of what was left Baby Bear ate 1/2 of what
was left after Mama Bear finished.
3) What fractional part of the pie did Mama Bear eat?
4) What fractional part of the pie was left for Goldilocks?
