Answer: 49 cookies
Step-by-step explanation: 7 dozen= 84 , so subtract 84 by the 2 cookies she ate and you'll get 82, now 2 dozen= 24, so now subtract the 24 cookies that she gave to her brother by 82 and you'll get 58, then subtract the nine cookies she gave to her mom by 58 and you'll get 49 cookies.
so basically,, 84-2= 82 -2 = 58 -9= 49

You deposit $20 in a savings account. The account earns 4% simple interest per year. What is the balance after 4 years?
Answer:
$23.20
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
I = 20 × 0.04 × 4 = 3.2
I = $ 3.20
The simple interest accumulated
on a principal of $ 20.00
at a rate of 4% per year
for 4 years is $ 3.20.
Based on the calculations, your balance after four (4) years is equal to $23.2.
Given the following data:
Interest rate = 4% = 0.04.Principal = $20.Time = 4 yearTo determine the balance after four (4) years:
How to calculate simple interest.Mathematically, simple interest is given by this formula:
[tex]I = PRT[/tex]
Where:
S.I is the simple interest.P is the principal or starting amount.R is the interest rate.T is the time measured in years.Substituting the given parameters into the formula, we have;
[tex]I=20 \times 0.04 \times 4[/tex]
Simple interest = $3.2.
Balance = [tex]3.2 +20[/tex] = $23.2.

Q3. x = 14, y = 7Q4. x = 29, y = 3Step-by-step explanation:
Question 3
Anglesx + 45° = 59° (exterior angle)x = 14°SidesThe triangle is right isosceles (45°)
The legs have equal length
10 + 2y + 1 = 4y - 34y - 2y = 11 + 32y = 14y = 7Question 4
The figure is a square
Sides5y + 3y = 248y = 24y = 3AnglesThe angle between sides 24 and 24 is the right angle
x + (9y + 5) + x = 90°2x + 9(3) + 5° = 90°2x = 90° - 32°2x = 58°x = 29°Write the equation of each circle
Center (-1,0) and containing the point (2, -4)
A.(x + 1)2 + y2 = 25
B.x2 + (y2 +1)= 25
Answer:
The equation of the circle is [tex](x + 1)^2 + y^2 = 25[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle of centre [tex](x_c,y_c)[/tex] has the following format:
[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]
In which r is the radius.
Center (-1,0)
This means that [tex]x_c = -1, y_c = 0[/tex]. So
[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]
[tex](x - (-1))^2 + (y - 0)^2 = r^2[/tex]
[tex](x + 1)^2 + y^2 = r^2[/tex]
Finding the radius:
Distance between the radius and the centre and a point of the circle. In this case, point (2,-4). Using the formula for the distance between two points:
[tex]r = \sqrt{(2-(-1))^2+(-4-0)^2} = \sqrt{3^2 + 4^2} = \sqrt{25} = 5[/tex]
So, the equation of the circle is:
[tex](x + 1)^2 + y^2 = 5^2[/tex]
[tex](x + 1)^2 + y^2 = 25[/tex]

Answer:
The key is to prove that the triangles are congruent, then their corresponding parts are congruent.
Step-by-step explanation:
#5)
It it given that:
Angle CBD is congruent to angle CDB.
Angle BAE is congruent to angle DEA.
Triangle CBD is isosceles because it's base angles are equal. Therefore, segment CB is congruent to segment CD.
Triangle CAE is isosceles because it's base angles are equal. Therefore, segment CA is congruent to segment CE.
CA-CB=BA
CE-CD=DE
segment BD is congruent to segment DB.
Angle ABD is supplementary to angle CBD (180-angle CBD= angle ABD).
Angle EDB is supplementary to angle CDB (1980-angle CDB=angle EDB).
therefore, angle ABD=angle EDB.
Triangles ABD and EDB are congruent because of the Side-angle-side theorem.
Triangles ABD and EDB are congruent, segment AD is congruent to segment EB because corresponding legs of congruent triangles are congruent.
#6)
It is given that:
Angle EBC is congruent to angle ECB
Segment AE is congruent to segment DE.
Triangle BEC is iscsceles because it's base angles are equal. Therefore, segment EB is congruent to segment EC.
AE+EC=AC
DE+EB=DB
segment BC is congruent to segment CB.
Triangle BAC is congruent to triangle CDB because of the side-angle-side theorem.
Segment AD is congruent to segment DC because corresponding legs of congruent triangles are congruent.
Answer:
Problem 5)
Step 1: < CBD = <CDB Reason: given
Step 2: BC = CD Reason: opposed sides in the isosceles triangle BCD
Step 3: < BAE = < DEA Reason: given
Step 4: AC = CE Reason: opposed sides in the isosceles triangle ACE
Step 5: triangle ACD = triangle BCE Reason: angle <C is common, and equal sides shown above so use SAS theorem.
Step 6: AD = BE Reason: third side in the equal triangles shown above.
Problem 6)
Step 1: < ECB = <EBC Reason: Given
Step 2> triangle BEC is isosceles Reason: has two equal angles
Step 3: BE = EC Reason: opposite sides in the isosceles triangle
Step 4: <DEC = < AED Reason: opposed by the vertex (vertical angles)
Step 5: AE = ED Reason: given
Step 6: triangle BAE = triangle EDC Reason SAS theorem
Step 7: side AB = side CD Reason: third side in the equal triangles

Describe how to find the vertex of a parabola if you are given the equation
Answer:
The vertex of a parabola is (h,k)
Step-by-step explanation:
The vertex form of a parabola is y=a(x-h)^2+k where a is the stretch/compression factor and (h,k) is the vertex. So to find the vertex, you will need (h,k) which represents the horizontal and vertical shift of the parabola

A cone has a volume of 3 pi and a radius of 1 what is its height
Answer:
The answer should be 2
Step-by-step explanation:
16 pi = 1/3 pi r^2 ( 12) Divide both sides by pi
16 = 1/3 r^2 (12) 1/3 * 12 = 4
16 = 4 r^2 divide both sides by 4
4 = r^2 You should be able to take it from here !
A sea lion swims in still water at the speed of 15 km/h. While hunting for fish, it swims with the current for 35 km and against the same current for 25 km. The sea lion swims with the current for the same amount of time it swims against the current. What is the speed of the current?
Answer:
x = 5/2 km/h
Step-by-step explanation:
Lets x be the speed of the current
The sea lion's speed with the current: 15 + x
The sea lion's speed against the current: 15 - x
Total distance in km with the current: 35
Total distance in km against the current: 25
Time with the current: 35/(15 + x)
Time against the current: 25/(15 - x)
So we do...
35/(15 + x) - 25/(15 - x) = 0
35(15 - x)/(15 + x) - 25(15 + x)/(15 - x): Having common denominators which is (15 + x)(15 - x)
525 - 35x - 375 - 25x = 0: Mutipling the (15 + x)(15 - x)to 0 getting 0
150 - 60x = 0
30(5 - 2x) = 0
x = 5/2
The speed of the current is 2.5 km/hr
Speed and DistancesFrom the given information
Lets x be the speed of the current
The sea lion's speed with the current will be 15 + xThe sea lion's speed against the current will be 15 - xAlso, we have that;
Total distance in km with the current to be 35 while the total distance in km against the current is 25
mathematically;
Time with the current = 35/(15 + x)
Time against the current = 25/(15 - x)
Equating both expression to get the value of "x
35/(15 + x) = 25/(15 - x) = 0
35/(15 + x) - 25/(15 - x) = 0
35(15 - x)/(15 + x) - 25(15 + x)/(15 - x)
Mutiplying the (15 + x)(15 - x)to have:
150 - 60x = 0
30(5 - 2x) = 0
x = 5/2
x = 2.5
Hence the speed of the current is 2.5 km/hr
