Answer:
Let the marked price =Rs100
After a discount of 20%, the price = 100−20% of100 = 100−10020×100 = 100−20=80
After a further discount of 5%, price = 80−5% of80 = 80−1005×80 = 80−4 = Rs76
Final Selling = Rs76
Total Discount = 100−76=Rs24
Thus, discount % = 10024×100 = 24%
McKenna was asked to write the following expression in standard form.
3−5(3a+6)
When writing the expression in standard from, McKenna made a mistake.
3−5(3a+6)
3+(−5)(3a+6) Step 1
−2(3a+6) Step 2
−6a+(−12) Step 3
−6a−12 Step 4
a. McKenna made her first mistake in ____________
Question 2
b. The correct expression in standard form is ______
basically pls fill in the blanks :]
Answer: -15a - 27
Step-by-step explanation:
McKenna made her first mistake in Step 2. You would need to multiply -5 by 3a and 6, not add it to 3 first.
The correct steps would be:
3−5(3a+6)
3+(−5)(3a+6) Step 1
3 - 15a - 30 Step 2
-15a - 27 Step 3
For a school fundraiser, Percy bought a big box of rubber ducks and wrote prize amounts, in dollars, on the bottom of each rubber duck. The prize amounts were $5, $10, $20, $50, and $100. The number of ducks with each prize amount varied so that the total value for all the ducks with each prize amount was always $500.
Percy then put all the rubber ducks in his school’s swimming pool. At the fundraiser, participants used a long net to catch a duck from the pool. They won the amount written on the bottom of the rubber duck, and then they threw the duck back into the pool before the next person’s turn. Since the ducks were returned to the pool after they were caught, the chances of winning any particular amount remained the same.

Una familia pasa sus vacaciones en un camping. Un día el padre le dice a Pedro que vaya a la fuente a buscar exactamente 4 litros de agua. Ahora bien, Pedro no dispone más que de 2 recipientes: un cubo de 5 litros de capacidad un pote de 3 litros
Answer:
Primero Pedro va al río con ambos recipientes.
Pedro llena el cubo de 5 litros.
Ahora (usando el agua del cubo de 5 litros) él puede llenar el pote de 3 litros.
De esta forma ahora tendrá:
3 litros de agua en el pote de 3 litros.
5 - 3 = 2 litros de agua en el cubo de 5 litros.
Ahora pedro debe vaciar el pote de 3 litros.
Ahora pedro pone los dos litros de agua que quedaban en el cubo grande en el pote de 3 litros.
En este momento tenemos:
2 litros de agua en el pote de 3 litros.
0 litros de agua en el cubo de 5 litros.
Ahora pedro deberá volver a llenar el cubo de 5 litros.
Con este cubo lleno, el pondrá agua en el pote de 3 litros hasta que se llene. Pero el pote de 3 litros ya tiene 2 litros, es decir, Pedro solo debe usar un litro del cubo para llenarlo.
Una vez pedro usa un litro del cubo, el agua restante en este será:
5 litros - 1 litro = 4 litros.
En este momento pedro tiene 4 litros de agua en el cubo de 5 litros.
Entonces puede vaciar el pote de 3 litros y regresar con exactamente 4 litros.
A family has two cars. The first car has a fuel efficiency of 40 miles per gallon of gas and the second has a fuel efficiency of 15 miles per gallon of gas. During
one particular week, the two cars went a combined total of 1625 miles, for a total gas consumption of 50 gallons. How many gallons were consumed by each of
the two cars that week?
Answer:
first car = 35, second car= 15
Step-by-step explanation:
40x+15y=1625
x+y=50
multiplying the 2nd by -15 and add the 2 equations, we get x= 35 and by substituting on second equation we get y= 15

Are the two triangles congruent ? Please answer correctly !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!
Answer
YES
Step by step Explanation
Answer:
There is not information given to assume the triangles are congruent.
Step-by-step explanation:
You can tell if two triangles are congruent by any of the following rules:
Three sides are congruent (SSS),
Two angles and a side in between are congruent (ASA)
Two sides and an angle in between are congruent (SAS)
Two angles and a side connected to one of those angles are congruent (AAS)
Note: SSA (Two Sides & One Angle) does not work. I good way to remember is that it spells a bad word backwards :)
In this case, there are only two sides given, but there aren't any angles, so there is not enough information to conclude if they are congruent or not.

Answer:
[tex]sinC = \frac{7}{25}\\~\\cosC = \frac{24}{25}\\~\\tanC = \frac{7}{24}[/tex]
Step-by-step explanation:
To get the sine of a non-right angle C in a right triangle, just divide the side opposing C by the long side. To get the cosine, divide the sides at C (shorter by longer). To get the tangent, divide the sine by the cosine.
Let's go:
[tex]sinC = \frac{7}{25}\\~\\cosC = \frac{24}{25}\\~\\tanC = \frac{7}{25} / \frac{24}{25} = \frac{7}{24}[/tex]
Answer:
sin(7/25), cos(24/25), tan(7/24)
Step-by-step explanation:
The sin, cos, and tan are found through the sides of the triangle.
The acronym SOH CAH TOA can be used to find which goes where.
S = sin
C = cos
T = tan
O = opposite
A = adjacent
H = hypotenuse
since it asks to use angle C you start from there, for sin its O/H hint by the SOH the rest are the same.

Find the surface area of the prism
Answer:
[tex]400\ cm^2[/tex]
Step-by-step explanation:
1. Approach
The surface area of an object is the two-dimensional area around the object. If one was going to wrap the figure in paper, then the surface area would be the amount of paper one would need to cover the entirety of the object. To find the surface area of an object, calculate the area of each face of the object and then add up the results,
2. Find the area of each face
The area of all the rectangular faces can be found by using the formula to find the area of a rectangle, ([tex]length*width[/tex]). Substitute in each of the values,
[tex]17*7=119[/tex]
[tex]15*7=105[/tex]
[tex]8*7=56[/tex]
Now find the area of the triangular faces. This can be done by using the formula for the area of a triangle, ([tex]\frac{(length)*(width)}{2}[/tex]). Substitute in the given values,
[tex]\frac{(15)*(8)}{2}=60[/tex]
[tex]\frac{(15)*(8)}{2}=60[/tex]
3. Find the total surface area
Now add up the values of the area for each of the faces of the prism,

Answer:
Step-by-step explanation:
The figure is a parallelogram. That means the y value of g is the same as the y value of H
G( ? , b)
The x value of G is a little harder. You have to be careful what you do to c.
A is at - c which means you need to add c to get to (0,0)
In addition, you go out d units to get to F. So the x value of G = c + d
the complete answer is G(c + d,b)
Suppose you invest $4,600 into a savings account with a 8.25% annual interest rate
that compounds interest monthly. Use the TVM solver on your calculator to find the
future value of the account after ten years.
NEED ANSWER ASAP
Answer:
$10,467.06
Step-by-step explanation:
The computation of the future value is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
here
rate of interest = 8.25% ÷ 12 = 0.6875%
And, the number of years is = 12 × 10 = 120
So, the future value is
= $4,600 × (1 + 0.6875%)^120
= $4,600 × 2.275448086
= $10,467.06
What is the Surface Area of the figure below?
A. 268 square inches
B. 134 square inches
C. 21 square inches
D. 240 square inches
Answer:
34.98 yds²
Step-by-step explanation:
To find surface area, we add together the area of each side. We have six sides, but there are three sets of identical sides, so it's easier to calculate.
We begin with the sides with dimensions 2.40 and 2.50. Multiply these together.
2.40 · 2.50 = 6
Since there are two of these sides, we can already say that the combined area of them is 12. So, we start the equation with 12.
Next, the two sides with dimensions 2.34 and 2.50. Multiply these together as well, to get 5.85. Multiply this by two to find the area of both sides, 11.7.
Add to our equation, for 12 + 11.7.
For the final two sides, we have the dimensions 2.34 and 2.40. Multiply to get 5.64. Multiply this again by two to find the area of both sides. We get 11.28. Add this to the equation as well, for 12 + 11.7 + 11.28= 34.98.
The answer is 34.98 yds². Good luck :)
