Answer:
Last year the cost was $28.
This year the cost is $36.
$36 - $28 = $8
Percent of increase = amount of increase ÷ original amount
$8/$28 = $0.286
$0.286 · 100 = 28.6%
There has been a 28.6% of change in the cost.

Step-by-step explanation:
SSS
PB = QC (Given) (S)
BC (common side) (S)
QB = PC (Since ABC is isosceles triangle and PB = QC) (S)
Topic: congruence and similarity
If you like to venture further, do check out my insta (learntionary) where I constantly post math tips! Thanks!
Answer:
SAS criteriaStep-by-step explanation:
Given is isosceles triangle as AB = AC, it means angles B and C measure same
Triangles PBC and QCB have common side BC, equal sides PB = QC as PB = AB - AP and QC = AC - AQ
So two sides and the angle between are congruent:
BC ≅ BC, PB ≅ QC, ∠PBC ≅ ∠QCBSo ΔPBC≅ΔQCB as per SAS criteriaPleaseeeeeeee helpppp-----------

A student can type
2
3
of a page in
1
5
hour. How many pages can the student type in an hour?
Answer:
A student can type 3.33 pages in 1 hour.
Step-by-step explanation:
(Assuming you mean 2/3 of a page and 1/5 of an hour)
To solve this we need to multiply both sides by 5. This is because when you multiply 1/5 by 5 you get 1 hour and what you do to one side you must do to the other.
1/5 * 5 = 1
2/3 * 5 = 3.3333
Rounding to the nearest hundredth:
3.33
A student can type 3.33 pages in 1 hour.

Leo Is Making A cAke for a friends birthday. The recipe tells him to bake the cake at 190* C for 35 minutes. To what temperature in *F should Leo bake the cake.
A. Use the *C formula to solve for F.
C = 5/9(F-32)
B. Use your new formula for *F to find the temperature equal to 190* C
Answer:
A). F = [tex]\frac{9C}{5}+32[/tex]
B). 374°F
Step-by-step explanation:
A). Formula to convert the temperature from degree centigrade to °F is,
C = [tex]\frac{5}{9}(F-32)[/tex]
We have to solve the formula to get the value of F,
9 × C = [tex]9\times \frac{5}{9}(F-32)[/tex]
9C = 5(F - 32)
[tex]\frac{9C}{5}=\frac{5(F-32)}{5}[/tex]
[tex]\frac{9C}{5}=(F-32)[/tex]
F = [tex]\frac{9C}{5}+32[/tex]
B). In this part we have to find the value of 190° C in °F.
From the formula given in part (A),
F = [tex]\frac{9\times 190}{5}+32[/tex]
= 374°
Therefore, 190°C = 374°F

Alexander is a stockbroker he earns 11% commission each week last week he sold $7,200 worth of stocks how much money did he make last week in commission
Answer:
Last week Alexander earned $792 in commissions.
Step-by-step explanation:
Giving the following information:
Commission= 11%
Sales= $7,200
To calculate the total commission, we need to use the following formula:
Total commission= commission rate*sales
Total commission= 0.11*7,200
Total commission= $792
Last week Alexander earned $792 in commissions.

Point Y is between the points X and Z. If XY = 3x – 4, YZ = 2x + 3,
and XZ = 24. What is the numerical length of YZ? Use mathematics
to justify your reasoning.
Answer: YZ = 13
Point Y is between the points X and Z => XY + YZ = XZ
=> 3x - 4 + 2x + 3 = 24
<=> 5x - 1 = 24
<=> x = (24 + 1) : 5 = 5
with x = 5 => YZ = 2.5 + 3 = 13
Step-by-step explanation:
The length of segment YZ can be found using the segment addition
postulate that specifies the relationship between the segments.
The numerical length of YZ is 13Reasons:
The given location of point Y = Between points X and Z
Length of XY = 3·x - 4
Length of YZ = 2·x + 3
Length of XZ = 24
Required:
The length of YZ
Solution:
XY + YZ = XZ according to segment addition postulate
Therefore;
3·x - 4 + 2·x + 3 = 24
Which gives;
5·x - 1 = 24
5·x = 24 + 1
[tex]x = \dfrac{24 + 1}{5} = 5[/tex]
x = 5
YZ = 2·x + 3
Therefore;
YZ = 2 × 5 + 3 = 13
The numerical length of YZ is 13
