Step-by-step explanation:
let x be the number of one- bedroom and y the number of two - bedroom apartments , then create 2 equations and solve simultaneously.
x + y = 12 ( subtract y from both sides )
x = 12 - y → (1)
360x + 450y = 4950 → (2)
substitute x = 12 - y into (2)
360(12 - y) + 450y = 4950 ← distribute parenthesis and simplify left side
4320 - 360y + 450y = 4950
4320 + 90y = 4950 ( subtract 4320 from both sides )
90y = 630 ( divide both sides by 90 )
y = 7
there are 7 two- bedroom apartments
y=x^2+8

Students of different ages are kept in a row,All of them have age difference of 3 years who are consecutive to each other. The age of first students row is 8 years. a) Restate the formula of to find the nth term of AP b) find the age of fourth student in rowc) find the sum of total ages if there are 20 students in a row
The formula to find the nth term of the AP is 8 + 3(n - 1).
How to calculate the values?a = first term = 8
d = common difference = 3
The nth term will be:
= a + (n - 1)d
= 8 + (n - 1)3
= 8 + 3(n - 1)
The age of the 4th student will be:
= a + (n - 1)d
= 8 + (4 - 1)3
= 8 + 9
= 17 years
The sum of total ages if there are 20 students in a row will be:
= n/2[2a + (n - 1)d]
= 20/2 [2×8 + (20 - 1)3]
= 10 [16 + (19 × 3)]
= 10(16 + 57)
= 10(73)
= 730

Please help me asap thanks
Answer:
100π
Step-by-step explanation:
The formula for the surface area of a sphere is SA = 4πr^2, where r is the radius of the sphere and SA stands for surface area. We are given that the radius is 5, so if we plug this into the formula, we get that SA = 4π*(5)^2, or SA = 4 * 25 * π. If we solve it out, we get 100π. If the software wants you to let π be 3.14 and evaluate, you will get approximately 314. I hope this helps
Mr. Suksod drives from his house to the office at a rate of speed of 82 km/h in 15 minutes. Mr.
Taylor, whose house is as far from the office as Mr. Suksod's, drives for 10 minutes to reach the
same office. What is the difference in the rate of speed that they drive?
The difference in speed is 41 km /hr.
What is the difference in speed?Average speed is the total distance travelled per time.
Average speed = total distance / total time
The first step is to determine the distance that Mr. Suksod drives.
Distance = average speed x time
82 x (15/60) = 20.50 km
The second step is to determine the average speed of Mr Taylor = 20.50 ÷ (10/60) = 123 km /hr
Difference in speed = 123 - 82 = 41 km /hr

Step-by-step explanation:
Given: ΔABC is isosceles; AB ≅ AC
Prove: ∠B ≅ ∠C
Triangle A B C is shown. Sides B A and A C are congruent.
We are given that ΔABC is isosceles with AB ≅ AC. Using the definition of congruent line segments, we know that .
Let’s assume that angles B and C are not congruent. Then one angle measure must be greater than the other. If m∠B is greater than m∠C, then AC is greater than AB by the .
However, this contradicts the given information that . Therefore, , which is what we wished to prove.
Similarly, if m∠B is less than m∠C, we would reach the contradiction that AB > AC. Therefore, the angles must be congruent.
AB = AC, they are equivalent. Since an isosceles triangle has the congruent angle property, mB = mC cannot be shown until AB=AC.
What is Isosceles triangles?Generally, Isosceles triangles are those that have two sides that are equal in length and two angles that are also equal in size.
Hence The sides and angles theorem for triangles., and the side AB is equal to the other side AC,
In conclusion, Assuming that the base angles, mB, and mC, are of equal measure, the triangle sides and angles theorem states that segment AC is larger than AB. The bigger angle of a triangle is always opposite to the longer side, according to the theorem.
AB is congruent to AC cannot be proven unless AB=AC then,
m<B = m<C because the isosceles triangle has the congruent angle property

A third-grade teacher is introducing the concept of multiplication using manipulatives, pictures, and arrays. Last year several parents asked why their child wasn't learning to multiply the same way that they did. What should the teacher do in order to address potential questions this year
Answer:
The 3rd-grade teacher should say that the school systems and ways of teaching get updated each year.
Step-by-step explanation:
Children's parent's schools would have probably taught different techniques and ways of learning a topic. As years go by, more efficient ways of learning that topic are presented and selected.
If the parent would like the child to learn that way, they may teach them at home, but the school has decided on a system for at-school learning that seems to have worked the best.
Hopefully, that should answer the parent's questions!
