Olive has 600 fruit trees. Some of the trees are apple trees. The rest of the trees are pears trees and plum trees in the ratio of 7:5 there are 175 plum trees what is the fraction of apple trees
Answer: 3/10
Step-by-step explanation:
Since the rest of the trees are pears trees and plum trees in the ratio of 7:5 and there are 175 plum trees, the number of pear trees will be:
= 175 ÷ 5/7
= 175 × 7/5
= 245
Plum trees = 175
Pear trees = 245
Apple trees = 600 - (175 + 245)
= 600 - 420
= 180
Fraction of apple trees = Number of apple trees / Total number of trees
= 180/600
= 3/10
Need help ASAP with maybe problem!!!
Answer:
-3
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. So, in this equation, the b or y-intercept value is missing. The y-intercept is where the line crosses the y-axis. In this case, the line crosses over at the value of -3. Therefore, the missing value is -3.

A pole that is 2.5 m tall casts a shadow that is 1.34 m long. At the same time, a nearby building casts a shadow that is 46.5 m long. How tall is the building? Round to the nearest meter
Answer:
86.8 m long
Step-by-step explanation:
A pole that is 2.5 m tall casts a shadow that is 1.34 m long. At the same time, a nearby building casts a shadow that is 46.5 m long. How tall is the building? Round to the nearest meter
We solve the above question using the Proportion formula:
Height of the pole/Shadow of the pole = Height of the building /Shadow of the building
Height of the pole = 2.5m
Shadow of the pole = 1.34 m
Height of the building = x
Shadow of the building = 46.5m
Hence:
2.5m/1.34m = x/46.5m
Cross Multiply
1.34m × x = 2.5m × 46.5m
x = 2.5m × 46.5m/1.34m
x = 86.753731343m
Approximately , The height of the building = 86.8 m
A book sold 32,100 copies in its first month of release. Suppose this represents 9.3% of the number of copies sold to date. How many copies have been sold to date? Round your answer to the nearest whole number.

345161.29
Thank you. And give my answer as Brainlist answer. Follow me for more
Step-by-step explanation:
Answer:
345,161
Step-by-step explanation:
It means that [tex]32,100=.093x[/tex]. Divide each side by .093, and you get 345,161, dropping the decimal, since you can't sell a fraction of a book.
Finance the formula in exercise 17 is the formula for computing simple interest, where I is interest P is principle of amount invested, r is the interest rate and t is the same tm in years. Find the amount of interest earned if you were to invest $5000 at 6% interest for 3 years.
Answer:
$900
Step-by-step explanation:
Given that:
Principal, p = 5000
Interest, r = 6%
Period, t = 3 years
Using the relation :
Simple interest = Principal * Rate * Time
Simple interest = $5000 * 0.06 * 3
Simple interest = $900
Hence, amount of interest earned = $900
what is domain and range because I got it wrong is not the right one
Answer:
You most likely got it wrong because you didn't plot all the points that are actually in the table, the domain and range are both right.

HELP!!!!!!!!!!!!!!!!!!!!!!! :)
Hey there!
The answers are as follows:
7.)
m∠1 = 85
m∠2 = 95
m∠3 = 85
m∠4 = 85
8.)
m∠1 = 60
m∠2 = 120
m∠3 = 60
m∠4 = 120
9.)
they all equal 90
10.) No. Parallel lines do not cross each other, but these, if extended, would cross. You could use a protractor by measuring corresponding angles, and if they aren't equal, they aren't parallel.

the questipn is: Given segment AB with endpoint (-2,-2) and (8,4), what is the coordinate of the midpoint?
Answer:
(3,1)
Step-by-step explanation:
If you plot both of the points on a graph you get another straight line.
When you connect the dots you get 3,1 as the midpoint of the two segments :))

A. Similar - AA
B. Similar - SSS
C. Similar - SAS
D. Cannot be determined
Answer: it’s D
Step-by-step explanation:
The correct postulate or theorem that applies is,
D. Cannot be determined
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Since, We have to given that,
Side AG = 10 units
And, ∠AGT ≅ ∠AGB.
Thus, options A and B are discarded.
Now, As for the SAS criteria, we need two sides to be congruent and their included angles to be congruent.
But, as no other information is given, we cannot determine whether the given triangles are congruent or not.
Hence, option D is correct.
