A and B are two similar shapes the area of shape A is 200cm2 calculate the area of shape B
Answer:
Area of shape B = 312.5 cm²
Step-by-step explanation:
Ratio of Area of A : Area of B = 12² : 15²
Given that area of A is 200 cm², let the area of shape B = x
Therefore:
200:x = 12²:15²
200/x = 144/225
Cross multiply
144x = 200*225
144x = 45,000
x = 45,000/144
x = 312.5 cm²
Area of shape B = 312.5 cm²

The length of a garden is 23m, correct to the nearest metre.
Write down the least possible length of the garden.
Answer:
22.5m
Step-by-step explanation:
Since it's correct to the nearest metre, it has an interval of ± 0.5
Using rounding concepts, it is found that the least possible length of the garden is of 22.5m.
------------------
If the first decimal digit is between 0 and 4, rounding to the nearest integer, the integer part remains the same.If the first decimal digit is between 5 and 9, rounding to the nearest integer, one is added to the integer part.Thus, in the context of this problem, garden lengths between 22.5 and 23.4 are rounded to 23m, and thus, the least possible length of the garden is 22.5m.A similar problem is given at https://brainly.com/question/13241511

2. The following triangle, ∆, has angle measures as shown.
Step 1: What is the measure of angle C? Show your work.
Step 2: What is the value of x? Show your work.
Answer:
x=29. Angle C= 93
Step-by-step explanation:
3(x+2)= 3x+6.
3x+6+52+35= 3x+93.
180-93=87.
87/3= 29. So that means x=29.
for proof you can do 3(29)+93 and you'll get 180.
For angle C; 3(29+2)= 3x31. 31x3= 93.
Angle C= 93 degrees.

Suppose a calculator manufacturer has the total cost function
C(x) = 22x + 6600
and the total revenue function
R(x) = 66x.
(a) What is the equation of the profit function P(x) for the calculator?
P(x) = _________
(b) What is the profit on 2800 units?
P(2800) = $________
Answer:
a) P(x) = R(x) - C(x)
P(x) = 66x - 22x - 6600 =
44x - 6600
b) P(2800) = 44(2800) - 6600 =
$116600

for #1 it's 1, 4, 5, 6
for #2 it's both lines have the same slope
for #3 it's both lines have a different y-intercept
Step-by-step explanation:
#1 explanation: all of them have the y-intercept of -8
ex. y = 3x (- 8) y = 5x (-8) y = 2x (-8) y = (1/3)x (-8)
#2 explanation: both have a slope of (1/4)
#3 explanation: y = (1/4)x there is not y-intercept that we know of and y = (1/4)x - 5 the y-intercept is at -5 therefore the y-intercepts are different
