It costs $520 to plant 4 acres of corn. How much would it cost to plant \large \frac{3}{5} acre of corn?
Answer:
$78 to plant 3/5 an acre of corn
Step-by-step explanation:
you can set up a fraction.
520/4 = x/6
Cross multiply
312 = 4x
Divide both sides by 4 equal to
x=78
$78 to plant 3/5 an acre of corn
Brianna rolls two number cubes labeled 1–6. What is the probability that Brianna rolls a sum of 5?
Answer: [tex]\dfrac{1}{9}[/tex]
Step-by-step explanation:
Given
Brianna roll two cubes labeled 1-6
To get a sum of 5, sample space is
[tex]n(s)=\{(1,4),(4,1),(2,3),(3,2)\}[/tex]
No of the elements in [tex]n(s)[/tex] is 4
The total outcomes possible is 36
[tex]\therefore \text{Probability }P=\dfrac{4}{36}\\\Rightarrow \dfrac{1}{9}[/tex]

Keisha took out a loan for 10,500 and was charged simple interest at an annual rate of 8.8%. The total interest she paid on the loan was $462. How long was the loan for, in months?
Answer: 6 months
Step-by-ste
462=(10,500)(0.88)t
462=924t
462/924=t
0.5=t
So the loan was 0.5 year's
Since we assume that there are 12 months in a year, the loan was 0.5 .12=6 months

Practice question — Given the trapezoid to the right find the length of legs in the following isosceles trapezoid
Given:
A figure of an isosceles trapezoid with bases 18 and 24, and the vertical height is 4.
To find:
The legs of the isosceles trapezoid.
Solution:
Draw another perpendicular and name the vertices as shown in the below figure.
From the figure it is clear that the AEFD is a rectangle. So,
[tex]EF=AD=18[/tex]
Since ABCD is an isosceles trapezoid, therefore in triangle ABE and DCF,
[tex]AB=DC[/tex] (Legs of isosceles trapezoid)
[tex]AE=DF[/tex] (Vertical height of isosceles trapezoid)
[tex]m\angle AEB=m\angle DFC[/tex] (Right angle)
[tex]\Delta ABE\cong \Delta DCF[/tex] (HL postulate)
[tex]BE=CF[/tex] (CPCTC)
Now,
[tex]BE+EF+FC=BC[/tex]
[tex]2BE+18=24[/tex]
[tex]2BE=24-18[/tex]
[tex]2BE=6[/tex]
[tex]BE=3[/tex]
Using Pythagoras theorem in triangle ABE, we get
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
[tex](AB)^2=(AE)^2+(BE)^2[/tex]
[tex](AB)^2=(4)^2+(3)^2[/tex]
[tex](AB)^2=16+9[/tex]
[tex](AB)^2=25[/tex]
Taking square root on both sides, we get
[tex]AB=\pm \sqrt{25}[/tex]
[tex]AB=\pm 5[/tex]
Side length cannot be negative. So, [tex]AB=5[/tex].
Therefore, the length of legs in the given isosceles trapezoid is 5 units.
There are 110 calories per 177.4 grams of Cereal X. Find how many calories are in 238.5 grams of this cereal
Answer: 147.87 calories
Step-by-step explanation:
Let the amount of calories in 238.5 grams of this cereal be represented by x.
Based on the information given, we can form an equation as:
110/177.4 = x/238.5
Cross multiply
177.4 × x = 238.5 × 110
x = (238.5 × 110) / 177.4
x = 147.87
Therefore, there are 147.87 calories in 238.5 grams of this cereal.
