Answer:
The answer is 94.25 sq.in
Step-by-step explanation:
Given rectangle- 7 1/4 in by 13
to fin area for one of the triangles
For triangle, base = 13 in, height = 7 1/4 in, = 29/4 in
Area- 1/3 x base x height = 1/2 x 13 x 29/4 in. 2
= 37/4 in. 2
= 94.25 sq. in

So KL is similar to PN
JL is similar to PM
So,
You need to find how much bigger is the second triangle from first.
It is proportionally scaled up.
KL/JL = PN/ PM
You basically put in order of triangles. Left triangle on left side of equal sign and right triangle on right side of equal sign. You put in denominator the similar sides and numerator the similar sides (the side that is similar to the side of the other triangle)
5/6 = PN / 9
Cross-multiply
PN * 6 = 5*9
6PN = 45
PN =45/6
PN =7.5
The value of PN is 7.5 if the triangles KLJ and NPM are similar triangles.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
The triangles KLJ and NPM are similar triangles.
So the sides of triangle are proportional.
KL/JL = PN/PM
Substitute the values:
5/6 = PN/9
Apply cross multiplication:
45=6PN
Divide both sides by 6:
45/6= PN
7.5=PN
Hence, the value of PN is 7.5.

Find the area of a rectangle that measures 3 1/4 yd long and 2 1/2 yd wide???
Answers
Answer:
Area of rectangle = 65/8 yd²
Step-by-step explanation:
The area of the rectangle is the length multiplied by the width. In this case, we are given the length 3 1/4 yd and the width 2 1/2 yd wide. Therefore,
⇒ Area of rectangle = (L × B) = (3 1/4 × 2 1/2) yd²
It is suggested to convert the terms in the expression (3 1/4 × 2 1/2) to improper fraction. Therefore,
⇒ Area of rectangle = [(3 × 4) + 1]/4 × [(2 × 2) + 1]/2 yd²
⇒ Area of rectangle = [(12) + 1]/4 × [(4) + 1]/2 yd²
⇒ Area of rectangle = [13]/4 × [5]/2 yd²
⇒ Area of rectangle = 13/4 × 5/2 yd²
Simplify the expression on the right hand side to determine the area.
⇒ Area of rectangle = 65/8 yd²
Thus, the area of the rectangle is 65/8 yd².

You spent 1/5 of your birthday money on 2 video games.If each video game cost the same amount.what fraction of your birthday money did each video game cost
Answers
Answer: 2/5
Step-by-step explanation: 1/5 divided by 2You do 1/5, then the 2 is a whole number so you have to always put a denominator under a whole number. The denominator will be 1.in this case you will do KCF or KFC KEEP, CHANGE FLIP.1/5 you will keep
you will CHANGE the division sign to multiplication, never change when it is multiplication.
1/5 X 1/2
You will FLIP 2/1 into 1/2. Now multiply numerator x numerator, denominator x denominator.
1/5 X 1/2= 2/5
Now you have gotten your answer but for the future, the numerator should never be greater than the denominator, if it is, divide.

The growth of bacteria makes it necessary to time-date some food products so that they will be sold and consumed before the bacteria count is too high. Suppose for a certain product the number of bacteria present is given by f(t)=600e0.1t, where t is time in days and the value of f(t) is in millions. Find the number of bacteria present at each time. (a) 2 days (b) 3 days (c) 1 week
Answers
a) Substitute t = 2 into the formula
= 600e^0.1(2)
= 600e^0.2
= 732.84 million
Therefore, 732.84 million bacteria are present after 2 days
b) Substituting t = 4 days we get
= 600e^0.1(4)
= 600e0.4
= 895.09 million
Hence, 895.09 million bacteria are present after 4 days
c) 2 weeks = 14 days
Substituting t = 14 days we get
= 600e^0.1(14)
= 600e^0.4
= 2433.12 million
Thus, 2433.12 million bacteria are present after 2 weeks
Factor rs - 5s + 5r - 25 by grouping
Answers
Answer:
(s+5)(r-5)
Step-by-step explanation:
From the first 2 terms, we can factor s to get
rs - 5s = s(r-5).
Similarly, we can factor 5 form the last 2 terms to get
5r - 25 = 5(r-5).
The original expression then becomes
s(r-5) + 5(r-5).
From here, we can treat (r-5) as a single term and factor the rest to get
(s+5)(r-5),
and we are done.

Subtract "y" both sides:
→ Зу - 15 = y + 1→ 3y - y - 15 = y - y + 1→ 2y - 15 = 1Add 15 both sides:
