what is the surface area of a square pyramid with side length 2 yd and slant height 4 yd.
Answer:
20 yd^2.
Step-by-step explanation:
Area of base = 2^2 = 4 yd^2.
It has 4 side faces so:
Area of each triangular side = 1/2 * 2 * 4 = 4 yd^2
Total surface area = 4 + 4(4).
= 20 yd^2.
a tree in dante's neighborhood grew 18 inches in the first 2 years after it was planted. if the tree continues to grow at this same rate, which graph best represents the growth of the tree in inches per year ?
Answer:
The third one would be the option.
Step-by-step explanation:
If the tree is already at 18 inches on the 2nd year, then it would be at 9 inches on the first year, and at 27 on the third year. And so on.
Graph [3] represents the growth of the tree in inches per year.
What is direct proportionality?Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. Mathematically, direct proportionality is represented by a straight line and it equation is of the form -
y = kx
k = y/x
where [k] is the constant
Given is a tree in Dante's neighborhood grew 18 inches in the first 2 years after it was planted. The tree continues to grow at this same rate.
Since the tree grew 18 inches in the first 2 years and continues at the same rate, then it will grew by (18/2) or 9 inches per year. The equation that will represent this relation between growth [y] and time [x] is given by -
y = 9x
Graph number [3] represents the relation.
Therefore, graph [3] represents the growth of the tree in inches per year

i need help in this fast
Answer:
D
Step-by-step explanation:
Letter D is the only answer that gets the transformation of triangle ABC correct, since it is the only answer that describes a reflection across line p.
Letter A describes a reflection across the y-axis, which is incorrect because the triangle on the right is farther away from the y-axis than the triangle on the left.
Letter B describes a reflection across the x-axis, which is incorrect because the topmost triangle is farther away from the x-axis than the bottommost triangle.
Letter C once again describes a reflection across the y-axis, which is incorrect for the same reason as to why letter A is incorrect.
Therefore, the answer must be letter D.
Some pls help me with number 6
Answer:
m∠CBD = m∠CDB ⇒ proved
Step-by-step explanation:
Let us solve the question
∵ AB ⊥ BD ⇒ given
→ That means m∠ABD = 90°
∴ m∠ABD = 90° ⇒ proved
∵ ED ⊥ BD ⇒ given
→ That means m∠EDB = 90°
∴ m∠EDB = 90° ⇒ proved
∵ ∠ABD and ∠EDB have the same measure 90°
∴ m∠ABD = m∠EDB ⇒ proved
∵ m∠ABD = m∠ABC + m∠CBD
∵ m∠EDB = m∠EDC + m∠CDB
→ Equate the two right sides
∴ m∠ABC + m∠CBD = m∠EDC + m∠CDB
∵ m∠ABC = m∠EDC ⇒ given
→ That means 1 angle on the left side = 1 angle on the right side, then
the other two angles must be equal in measures
∴ m∠CBD = m∠CDB ⇒ proved

- 4n > 2.7 - 0.3
- 4n > 2.4
[tex]\frac{-4n}{-4}[/tex] < [tex]\frac{2.4}{-4}[/tex]

-4n > 2.7 - 0.3
-4n > 2.4
-4n/-4 > 2.4/-4 (Divide both sides by -4)
n > -0.6

Answer:
72 ounces.
Step-by-step explanation:
Convert all the fractions to denominator of 24
9/24 4/24 10/24 = 23/24
23/24 = 69/1 so you can cross multiply ( i think)
Then you get 1656 / 23 which equals 72.
If this is wrong I am so sorry
===================================================
Explanation:
He uses 3/8 of the amount to make bread, 1/6 of the amount to make pancakes, and 5/12 of the amount to make jam.
Add up those fractions. But first let's make each fraction have the LCD (lowest common denominator) of 24
3/8 = 9/24 .... multiply top and bottom by 3
1/6 = 4/24 .... multiply top and bottom by 4
5/12 = 10/24 .... multiply top and bottom by 2
Now we can add the fractions:
(3/8) + (1/6) + (5/12)
(9/24) + (4/24) + (10/24)
(9+4+10)/24
23/24
So in total, Wayne used up 23/24 of all the blueberries he bought.
Let's make this unknown amount x
x = amount of blueberries he bought, in ounces
Multiplying the sum we got (23/24) by x leads to the amount of blueberries he used, which is 69 ounces
So,
(fraction used)*(amount he bought) = (amount he used)
(23/24)*x = 69
23x = 69*24 .... multiply both sides by 24
23x = 1656
x = 1656/23 ... divide both sides by 23
x = 72
He bought 72 ounces of blueberries.
------------------------------
Let's check that answer
A = 3/8 of 72 = (3/8)*72 = 27 = amount used for bread
B = 1/6 of 72 = (1/6)*72 = 12 = amount used for pancakes
C = 5/12 of 72 = (5/12)*72 = 30 = amount used for jam
A+B+C = 27+12+30 = 69 = total amount used
This confirms our answer.

The image shows parallel lines cut by a transversal. The expressions represent unknown angle measurements. What is the value of x
A)48
B)51
C)54
D)57
Angles 2·x + 2, and x + 50, formed by the transversal are alternate
exterior angles, which gives, x = 48°, the correct option is therefore;
A) 48
How can the value of x be calculated?
From the position of the angles image showing two parallel lines having
a common transversal we have;
Angle 2·x + 2 and angle x + 50 are alternate exterior angles
The alternate exterior angles formed by two parallel lines that have a
common transversal are equal, therefore;
2·x + 2 = x + 50
Which gives;
2·x - x = 50 - 2 = 48
x = 48°

7. In an orchestra, the ratio of trombones to violas is 4:6. There are 9 violas. Write and solve a proportion to
determine how many trombones are in the orchestra.
Answer: 6 trombones
Step-by-step explanation:
We can set up a proportion.
Let x be the number of trombones there are.
[tex]\frac{4 trombones}{6violas} = \frac{x trombones}{9 violas}[/tex]
We can cross multiply:
4*9 = 6x
6x = 36
Divide both sides by 6:
x = 6
