Answer:
e. the triangles are congruent
Step-by-step explanation:
Similar means they're alike but are not the same, congruent means they're the same. The triangles are the same so therefore they're congruent.
Also it's congruent because u see the triangles on the bottom and top line? It means that the lines are parallel. So the lines at the side have to be the same length and tilt in an equal way so the top and bottom lines can be parallel

a) 4865
(Nearest ten)
Answer:
irst, 4865 rounded to the nearest ten is:
4870
Step-by-step explanation:
Here we will tell you what 4865 is rounded to the nearest ten and also show you what rules we used to get to the answer.
Remember, we did not necessarily round up or down, but to the ten that is nearest to 4865.
When rounding to the nearest ten, like we did with 4865 above, we use the following rules:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
∠A and \angle B∠B are vertical angles. If m\angle A=(3x+26)^{\circ}∠A=(3x+26) ∘ and m\angle B=(x+20)^{\circ}∠B=(x+20) ∘ , then find the value of x.
Answer:
The value of x is -3
Step-by-step explanation:
The vertical angles are equal in measures∵ ∠A and ∠B are vertical angles
→ By using the rule above
∴ m∠A = m∠B
∵ m∠A = (3x + 26)°
∵ m∠B = (x + 20)°
→ Equate their measures
∴ 3x + 26 = x + 20
→ Subtract x from both sides
∵ 3x - x + 26 = x - x + 20
∴ 2x + 26 = 20
→ Subtract 26 from both sides
∵ 2x + 26 - 26 = 20 - 26
∴ 2x = -6
→ Divide both sides by 2
∵ [tex]\frac{2x}{2}[/tex] = [tex]\frac{-6}{2}[/tex]
∴ x = -3
∴ The value of x is -3
witch is grater 18/24 or 55%
Answer:
i would say 18/24
Step-by-step explanation:
27 : 18 = 13 : x find x
Answer: 27:18 and 13:x can also be written as 27/18 and 13/x
therefore, 27:18 = 13:x
27/18 = 13/x
27/18 *13= x
x = 19.5

B. Solve the problem:
Mrs. Reyna is planning to fence her vacant lot for a parking space. The desired length of the lot is 6 m longer than its width. What will be the possible dimensions of the rectangular parking space if it should be less than 40m2?
(Hint: length x width = Area of rectangle)
Answer:
Step-by-step explanation:
Given
Area of the rectangle =Length × width
Given
The desired length of the lot is 6 m longer than its width, then L = 6+W
A = LW
40 = (6+W)W
40= 6W+W²
W²+6W -40 = 0
W²+10W-4W-40 = 0
W(w+10)-4(w+10) = 0
W+10 = 0 and w-4 = 4
W = -10 and w = 4
Width can't be negative
W = 4m
Since L = 6+w
L = 6+4
L = 10m
Hence the possible dimension s 4m by 10m

Ms. Hogan paid $13.25 for 5 tacos and 1 soda. The price of a taco is $2.50. What is the price of the soda?
Answer: $0.75
Step-by-step explanation:
To solve this problem, we can create 2 equations. Let's use x for tacos and y for soda.
Equation 1: 5x+y=13.25
Equation 2: x=2.5
Since we know the value of x, we can plug it into Equation 1 to solve for y.
5(2.5)+y=13.25 [multiply]
12.5+y=13.25 [subtract both sides by 12.5]
y=0.75
Now, we know the price of the soda is $0.75.
Answer:
The soda costs $0.75.
Step-by-step explanation:
We are given that Ms. Hogan paid $13.25 for 5 tacos and one soda. We are also given that one taco costs $2.50. Therefore, we can set up a system of equations to solve for how much a soda costs.
[tex]\displaystyle\left \{ {{5x + y = \$13.25} \atop {x = 2.50}} \right.[/tex]
This is our required system of equations. We are given that one taco costs $2.50, so this is our x. Therefore, the price of one soda is y.
We can use the second equation and substitute it in place of the x in the first equation to solve for the price of the soda.
[tex]\displaystyle5x+y=\$13.25\\\\5(2.50)+y=\$13.25\\\\12.5 + y = \$13.25\\\\y = \$0.75[/tex]
Therefore, one soda costs $0.75.
Someone please answer its due by midnight
Answer:
Look below :)
Step-by-step explanation:
1. coefficient
2. constant (it's referred to as a constant because the value never changes)
3. This polynomial has 4 terms. We know this by counting them. 5x^3 is one term, -x^2 is the second term, 5x is the third term, and -8 is the fourth term.
4. In descending order: 2, 1, 3, 4. The degree is the same value as the exponent. For the last term, x^2y^2, you add the values of the exponents together to get the degree.
5. -2 is the coefficient. The term with the third degree, or has 3 as the exponent, is -2x^3.
6. 1 is the coefficient. The term with the second degree is x^2. When the coefficient is 1, usually the 1 isn't written because any number multiplied by 1 equals that number (x * 1 = x)
7. 5 is the degree of the polynomial. To find the degree of a polynomial, find whichever term has the highest value for an exponent. In this case, 5 is the highest exponent.
8. 2 is the degree of this polynomial. Although none of the terms may look like they have a degree of 2, in order to find the actual degree of 4xy you have to add the values of the degree of x and y to find the actual degree. If x and y both have a degree of 1, you add those together to make 2.
9. 2[tex]x^{3}[/tex] - 7[tex]x^{2}[/tex] + 5x - 15. To order a polynomial from highest to lowest you have to order the terms in decreasing value of their exponents.
10. -4[tex]x^{3} y[/tex] + 2xy + 5x + 7.

The volume of a solid cube is 1700m3.
Work out the surface area.
Give your answer rounded to 1 DP.
Answer:
849.7m2
Step-by-step explanation:
L= length
SA = surface area
volume = L x L x L
1700= L x L x L
find cube root
=11.93m
round off to 1 dp
=11.9m
SA= 6( L x L)
= 6( 11.9 x 11.9)
=6(141.61)
=849.66m2
round off to 1 dp
=849.7m2
(2x+y,x+3y)=(12,11)
Answer:
x=5, y=2
Step-by-step explanation:
Use the information given:
2x+y=12x+3y=11Subtract them because we have two variables and two equations:
2x+y=12
- x+3y=11
–––––––––
x-2y=1
We can by 1+2y (Add 2y to both sides) instead of x:
2(1+2y)+y=122+4y+y=122+5y=125y=10y=2(1+2y)+3y=111+2y+3y=111+5y=115y=10y=2Now we can figure out x as we know y:
2x+1(2)=122x+2=122x=10x=5x+3(2)=11x+6=11x=5need help if you can....
Answer:
40, 80, 120
Step-by-step explanation:
0, 40, 80, 120, 160, 200
+40
Answer:
0, 40, 80, 120, 160, 200
Step-by-step explanation:
The numbers are decreasing by 40. 200-160=40. Therefore, we need to subtract 40 each time from every number we get.
160-40=120
120-40=80
80-40=40
Now, plug the numbers into the sequence. It should now look like this:
0, 40, 80, 120, 160, 200

Mrs. Coughlin bought 2.25 pounds of turkey at $4.96 per pound and 0.75 pound of provolone cheese at $5.20 per pound. If Mrs. Coughlin gave the cashier $20, how much change will she receive?
Answer:
$4.94
Step-by-step explanation:
To find out the change from $20, we need to find her total cost.
Total cost = 2.25lbs * $4.96/lb + 0.75lbs * $5.20/lb
Total cost = $11.16 + $3.90 = $15.06
Now $20 - total cost = $20 - $15.06 = $4.94
