14. How many odd 2-digit positive integers greater than 20 are there?
Answer:
40
Step-by-step explanation:
21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99
We will see that there are 35 two-digit odd numbers larger than 20.
How many odd 2-digit positive integers greater than 20 are there?So in each range of 10 consecutive numbers, we have 5 odd ones.
For example, between 20 and 30 we have:
{21, 23, 25, 27, 29}
And from 20 to 100 (we count to 100 because we only care for 2-digit integers) there are 7 sets of 10s
(20 to 30), (30 to 40), (40 to 50), (50 to 60), (60 to 70), (70 to 80), (80 to 90), (90 to 100).
And we know that in each one of these 7 sets we have 5 odd numbers, so we can conclude that there are:
7*5 = 35 2-digit odd numbers larger than 20.

What is the dollar value of 10 nickels and 1 dime? What is the dollar value of n nickels and d dimes?
Answer:
10 nickels and 1 dime would be $0.60
Step-by-step explanation:
10x5 = 50+ 10 =60
It is 0.60 cent. 10 nickels is .50 cent and 1 dime is .10 cent so the total would be 0.60 cent. 10n+1d=.60.
Which measurements could create more than one triangle?
A. A triangle with sides measuring 5 cm, 10 cm, and 15 cm
B. A triangle with sides measuring 5 inches, 7 inches, and 9 inches
C. A triangle with sides measuring 50 mm and 35 mm and a
nonincluded angle measuring 25°
O D. A triangle with sides measuring 8 cm and 12 cm and an included
angle measuring 85°
Using rules of congruency, option C. A triangle with sides measuring 50 mm and 35 mm and a nonincluded angle measuring 25°, can create more than one triangle.
What is congruency?Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure i.e., the triangles are of same size and shape.
Since part A and B follow SSS congruency, thus for such measures, there can only be one triangle. Similarly, part D follows SAS congruency.
But for part C, there is no congruency as SSA.

Curtis sees a maple tree and a pine tree in the forest. He knows that the pine tree is 20.68 feet tall. On a sunny day, the shadow of the pine is 4.2 feet long while the maple's shadow is 20.02 feet long. Estimate the height of the maple tree.
Answer:
The height of the maple is 98.6 feet
Step-by-step explanation:
Similar Triangles
The triangles formed by each tree's height, their shadow, and the projection of their shadow in the ground are right and similar triangles since the sun has the same elevation at the same time in the same place. It's shown in the image attached.
Curtis sees a maple tree of unknown height Hm and a pine tree of height Hp=20.68 feet. He also measures the projection of the shadow of the pine of Xp=4.2 feet and the same measure of the maple of Xm=20.02 feet.
Since both triangles are similar, the proportion between their sides is equal, thus:
[tex]\displaystyle \frac{Hm}{Hp}=\frac{Xm}{Xp}[/tex]
Solving for Hm:
[tex]\displaystyle Hm=\frac{Xm*Hp}{Xp}[/tex]
[tex]\displaystyle Hm=\frac{20.02*20.68}{4.2}[/tex]
Hm = 98.6 feet
The height of the maple is 98.6 feet

solve for X
The sum of the inside angles of a 6 sides figure is 720
Add the known angles together:
90 + 112 + 131 + 154 + 118 = 605
Subtract the sum of the known angles from 720 for x:
x = 720 - 605 = 115
x = 115 degrees.
Answer:
The sum of the interior angles of the hexagon is 720°
[tex]x + 154 + 131 + 112 + 90 + 118 = 720 \\ x + 605 = 720 \\ x = 720 - 605 \\ \boxed{x = 115}[/tex]

Multiply the number by 4. Add 2 to the product. Divide this sum by 2. Subtract 1 from the quotient. The first number is 1.
Answer:
2
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
First number = 1
So by making the equation, we get
Multiply first number by 4
= 1 × 4 = 4
Add 2 to product
= 4 + 2 = 6
Now, Divide sum by 2
= 6 ÷ 2 = 3
Now, subtract 1 from the quotient
= 3 - 1 = 2
Hence, 2 is the correct answer.
