You have to prove the triangle congruent by SSS (side side side), SAS (side angle side), ASA (angle side angle), AAS (angle angle side), and HL (hypotenuse leg). I proved this triangle by SAS because they already told us that < A and < D are congruent and that line BC is congruent to line EC. So I just had to prove that <ACB and <DCE are congruent, and since they are vertical angles they have to be congruent.

Answer: Mom bought 10 chickens
Step-by-step explanation: if each chicken had 2 wings and there were 20 wings you divide
Answer:
3. Zack has 6 times more seeds than Ben, if Ben has 5 seeds, just multiply how many seeds Ben has by 6, which means Zack planted 30 seeds (This can be written Z=B*6, where Z is how many seeds Zack has, and B is how many seeds Ben has)
1. If there are a total of 40 cards divided into 8 groups of students, that means that each group got 5 card (40 ÷ 8 = 5)
2. If each chicken has 2 wings, and she has a total of 20 wings, that means that she bought a total of 10 chickens (20 ÷ 2 = 10)
Complete the pairs of corresponding parts if △RST ≅ △TXY.
∠STR =
∠ XYT
∠ TXY
∠ XTY
Answer:
∠STR is associated with ∠ XYT
Therefore, we conclude that:
∠STR = ∠ XYTStep-by-step explanation:
Given
△RST ≅ △TXY
To determine:
∠STR = ?
As
△RST ≅ △TXY
So the triangles △RST and △TXY are congruent to each other.
We know that congruent triangles have equal corresponding parts.Please check the attached graph.
From the graph, it is clear that:
∠STR is associated with ∠ XYT
so
∠STR = ∠ XYT
Therefore, we conclude that:
∠STR = ∠ XYT2z+3=5 can someone help me find z

3 = g/-4 - 5
Answer:
g=-32
Step-by-step explanation:
Switch sides
g/-4 -5 = 3
Add 5 to both sides
g/-4 -5+5=3+5
Simplify
g/-4 = 8
Multiply both sides -4
g(-4)/-4 = 8(-4)
Simplify
g=-32

Answer:
93 Sq.ft
Step-by-step explanation:
Formula for total surface area of a cylinder is;
TSA = 2πr² + 2πrh
In the question, we have Half cylinder, thus; TSA for half cylinder is;
TSA_½ = (2πr² + 2πrh)/2
TSA_½ = πr² + πrh
r = 3/2 = 1.5 ft
h = 5 ft
Thus;
TSA_½ = π(1.5)² + π(1.5 × 5)
TSA_½ = 30.63 Sq.ft
Surface area of rectangular prism is;
SA = 2(lw + lh + wh)
We have;
l = 5 ft
h = 2 ft
w = 3 ft
Thus;
SA = 2((5 × 3) + (5 × 2) + (2 × 3))
SA = 2(15 + 10 + 6)
SA = 62 Sq.ft
Thus, surface area of treasury is;
S.A_t = TSA_½ + SA
S.A_t = 30.63 + 62
S.A_t = 92.63 approximately 93 Sq.ft

Find the perimeter in simplest form and explain your work
9514 1404 393
Answer:
7 1/8 yd
Step-by-step explanation:
The perimeter is the sum of the three side lengths. They are all the same, so we can use multiplication to find their sum.
P = 3·(2 3/8 yd) = 6 9/8 yd . . . . . 9/8 = 1 1/8
P = 7 1/8 yd
The perimeter is 7 1/8 yards.
Answer:
[tex]perimeter \: of \: the \: triangle \\ = 2 \frac{3}{8} +2\frac{3}{8} + 2 \frac{3}{8} \\ = 3 \times 2 \frac{3}{8}\\= 3 \times \frac{19}{8} \\ = \frac{57}{8} \: yd \\ = 7 \frac{1}{8} \: yd[/tex]

The formula for the volume of a sphere is V space equals space 4 over 3 Ïr cubed. Find the radius to the nearest hundredth of a sphere with each volume. 20 ft 3 i really need to know the answer
Answer:
r = 1.68 ft
Step-by-step explanation:
Volume of a sphere, V = 4/3πr³
V = 20 ft³
π = 3.14
r = ?
V = 4/3πr³
20 = 4/3 × 3.14 × r³
20 = (4×3.14×r³)/3
Cross product
20 × 3 = 4 × 3.14 × r³
60 = 12.56r³
r³ = 60/12.56
= 4.7771
r = 3√4.7771
= 1.6842
Approximately
r = 1.68 ft to the nearest hundredth

Step-by-step explanation:
eduardo baked 150 muffins 1/5 of the muffins are banana 1/2 of the muffins are blueberry the rest are strawberry, how many muffins are strawberry
Answer:
45 strawberry muffins
Step-by-step explanation:
In order to solve this equation you are going to have to multiply 150 by 1/5 bananas and 1/2 blueberry in order to get how much strawberry muffins were made. So first we are going to convert 1/5 and 1/2 into decimals:
1/5 = 0.2
1/2 = 0.5
Now we are going to multiply 0.2 and 0.5 by 150 in order to figure out how much banana and Blueberry muffins were made:
0.2 * 150 = 30
0.5 * 150 = 75
So 30 banana muffins were made and 75 blueberry muffins were made, now that we know this we are going to add 30 and 75 together and subtract the answer from 150. THe reason we are subtracting 75 + 30 from 150 is because we are trying to segregate the strawberry muffins from the total number:
75 + 30 = 105
now we subtract:
150 - 105 = 45
So the number of strawberry muffins made was 45.
I hope this helps.
Answer:
The total number of strawberry muffins are: 45
Step-by-step explanation:
Total baked muffins = 150
1/5 of the muffins are banana, so
Banana muffins = 1/5 × 150
= 30
1/2 of the muffins are blueberry, so
Blueberry muffins = 1/2 × 150
= 75
The rest are strawberry, so
Strawberry muffins = Total muffins - Banana muffins - Blueberry muffins
= 150 - 30 - 75
= 45
Therefore, the total number of strawberry muffins are: 45
What is the following sum? Assume x greater-than-or-equal-to 0 and y greater-than-or-equal-to 0
Answer:
[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}=2xy^2\sqrt{x}+2xy\sqrt{y}[/tex]
Hence, ption B is true.
Step-by-step explanation:
Given the expression
[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}[/tex]
solving the expression
[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}[/tex]
as
[tex]\sqrt{x^2y^3}=xy\sqrt{y}[/tex]
[tex]2\sqrt{x^3y^4}=2xy^2\sqrt{x}[/tex]
so the expression becomes
[tex]\:\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}=xy\sqrt{y}+2xy^2\sqrt{x}+xy\sqrt{y}[/tex]
Group like terms
[tex]=2xy^2\sqrt{x}+xy\sqrt{y}+xy\sqrt{y}[/tex]
Add similar elements
[tex]=2xy^2\sqrt{x}+2xy\sqrt{y}[/tex]
Therefore, we conclude that:
[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}=2xy^2\sqrt{x}+2xy\sqrt{y}[/tex]
Hence, option B is true.

Find the product of the expression:
(5p^3) (-1m^8p^2)
Answer:
We conclude that:
[tex]\left(5p^3\right)\:\left(-1m^8p^2\right)=-5p^5m^8[/tex]Step-by-step explanation:
Given the expression
[tex]\left(5p^3\right)\:\left(-1m^8p^2\right)[/tex]
Apply the rule:
[tex]a\left(-b\right)=-ab[/tex]
so the expression becomes
[tex]\left(5p^3\right)\left(-1\cdot \:m^8p^2\right)=-5p^3\cdot \:1\cdot \:m^8p^2[/tex]
Apply the rule:
[tex]a^b\cdot \:a^c=a^{b+c}[/tex]
so the expression becomes
[tex]=-5p^{3+2}\cdot \:1\cdot \:m^8[/tex] ∵ [tex]p^3p^2=p^{3+2}[/tex]
[tex]=-5p^5\cdot \:1\cdot \:m^8[/tex]
[tex]=-5p^5m^8[/tex]
Therefore, we conclude that:
[tex]\left(5p^3\right)\:\left(-1m^8p^2\right)=-5p^5m^8[/tex]Walking Robert walks 7 blocks east from his home and arrives at his favorite restaurant. When he arrives, he discovers that he dropped his wallet along the way. He retraces his steps for 5 blocks until he finds his wallet. An expression for how many blocks east Robert is from his home after finding his wallet is the sum 7+(−5).
Answer:
2 block east from home
Step-by-step explanation:
Given an expression for how many blocks east Robert is from his home after finding his wallet as the sum 7+(−5),
Simplifying the given expression
7+(-5) = 7-5 (note that the product of a plus and minus sign will give a minus sign)
7-5 = 2
Hence Robert will be 2 block east from home
