Question:-
Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.
_______________________________________________
Solution:-
In an equilateral triangle all sides are equal.
Let s = side length = 9 cm
Then, area of equilateral triangle is given as:
A = (√3/4)s²
Putting the value of s here,
A = (√3/4) * (9 cm)²
=> A = (√3/4) * 81 cm²
=> A = √3 * 20.25 cm²
We know that, √3 = 1.732
=> A = 1.732 * 20.25 cm²
=> A = 35.073 cm²
Rounding to one decimal place,
=> A = 35.1 cm²
_______________________________________________
The answer is 35.1 cm².
Hope this helps; have a great day!

Step-by-step explanation:
Makayla has $740 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
She buys a new bicycle for $465.34.
She buys 4 bicycle reflectors for $13.25 each and a pair of bike gloves for $18.12.
She plans to spend some or all of the money she has left to buy new biking outfits for $25.69 each.
What is the greatest number of outfits Makayla can buy with the money that's left over?
Number of biking outfit Makayla buy is 7
Given:
Total amount spend by Makayla = $740
Cost of bicycle = $465.34
Cost of 4 bicycle reflectors = $13.25(each)
Cost of pair gloves = $18.12
Cost of each biking outfit = $25.69 each
Find:
Number of biking outfit Makayla buy
Computation:
Assume;
Number of biking outfit Makayla buy = a
Total cost = Cost of bicycle + Total Cost of 4 bicycle reflectors + Cost of pair gloves + Total cost of biking outfit
465.34 + 4(13.25) + 18.12 + a(25.69) = 740
465.34 + 53 + 18.12 + a(25.69) = 740
536.46 + a(25.69) = 740
a(25.69) = 740 - 536.46
a(25.69) = 203.54
a = 7.9229
Rounding number to less
So.
Number of biking outfit Makayla buy = 7 (Approx.)

Help me please just need this last one and I’ll be done please help me if you can
Answer:
58°
Step-by-step explanation:
Start with the equation 2x + 2 + 90 = 148
( I got the 90 from Angle B since it is a right angle.)
Combine like terms 2x + 92 = 148
( 90 and 2 didn't have variables so you could add them together.)
Subtract 92 from both sides 2x + 92 = 148
-92 -92
(The opposite of addition is subtraction.)
Now write out the new equation 2x = 56
Divide both sides by 2 [tex]\frac{2x}{2}[/tex] = [tex]\frac{56}{2}[/tex]
You'll end up with... x = 28
To find the measure of angle BAC, plug in 28 where the x value is 2(28) + 2
This gives you the answer 58°

The ratio of yellow flowers to the total number of flowers in a bucket is 5 to 9. How many flowers are yellow if there are 45 lowers in all
Answer:
There are 25 yellow flowers.
Step-by-step explanation:
The ratio is yellow/all and 5/9.
We know that all the flowers in total equal 45, which is a multiple of 9.
So 45 divided by 9 = 5.
So all I had to do was multiply 5/9 times 5/5.
So then we get the ratio of 45 total flowers with 25 yellow flowers.

Answer:
missing angle = 41, b. 45, c. 72
Step-by-step explanation:
A circle has 360 degrees, so add all of the existing angles
48+45+129+97 = 319 and 360-319 = 41
25/200 = 12.5% so 12.5% of 360 = .125x360 = 45
Sector 129 represents 129/360 = 35.83% so 200x.3583=72 cars
How much wrapping paper is needed to cover a box (rectangular prism) that measures 6 feet by 2.5 feet by 3 feet?
Answer:
81 feet ²
Step-by-step explanation:
Given that:
Dimension of rectangular prism :
6 feets by 2.5 feets by 3 feets
To obtain the amount of wrapping paper required to cover the box ; we find the area of the box ;
Area of box = 2(wl + hl + hw)
Area of box = 2(6*2.5 + 6*3 + 2.5*3)
Area of box = 2(15 + 18 + 7.5)
Area of box = 81 feet²

Find an equation for the perpendicular bisector of the line segment who’s endpoints points are (-9,3) and (1,7).
Answer:
y = 2/5x + 33/5
Step-by-step explanation:
(-9,3) and (1,7)
m=(y2-y1)/(x2-x1)
m=(7-3)/(1+9)
m=4/10
m = 2/5
y - y1 = m(x - x1)
y - 3 = 2/5(x + 9)
y - 3 = 2/5x + 18/5
y = 2/5x + 33/5
