29 plus x Equals 90 im a lil smart so ntm

Traingle PQR is shown below a rotation of 180 about point M followed by a dilation centered at M with scale factor 2 is applied

grigory [225]

Answer:

Step-by-step explanation:

Cannot give you the number because we are not given the diagram.

However, it will be exactly the same as the measure of angle R in the original triangle PQR.

Rotation and dilation do not change angles.

the slope of a line is 3/2 and the line contains the points (5,9) and (3, a). what is the value of a?

vivado [14]

Y = mx + b
slope(m) = 3/2
(5,9)...x = 5 and y = 9
now we sub and find b, the y int
9 = 3/2(5) + b
9 = 15/2 + b
9 - 15/2 = b
18/2 - 15/2 = b
3/2 = b
so ur equation is : y = 3/2x + 3/2.........(3,a)....so x = 3

y = 3/2(3) + 3/2
y = 9/2 + 3/2
y = 12/2
y = 6

so ur missing value is 6...a (or y) = 6

HELP ASAP Three generous friends, each with some cash, redistribute their money as follows: Ami gives enough money to Jan and To

DENIUS [597]

Answer:

$252

Step-by-step explanation:

This is quite a neat question, with no fixed equation. Given that each person gives the other two enough money to double their cash, if Toy had 36 dollars beginning, and 36 at the end - presumably the cash of each person, ( their starting and original ) should be the same as well. Respectively each should be a multiple of 36 dollars.

Jan's " give away " = Ami + 36, Jan - 108, Toy + 72

Toy's " give away " = Ami + 72, Jan + 36, Toy - 108

Therefore, we can conclude that Ami = 144 at the start, presuming he gave away 108 dollars, with a remaining 36. Jan, having 144 dollars ( after having his 72 dollars doubled by Ami ) gives 36 to Ami to double his amount, and 72 to double Toy's doubled amount, remaining with 36 dollars. Now Ami has 72 dollars, Jan has 36, and Toy has 144. Then, Toy double's Ami and Jan's amount, giving away 72 and 36 dollars, remaining with 36 dollars himself. Therefore, Ami has 144 dollars, Jan has 72 dollars, and Toy has 36 dollars both at the beginning and end.

144 + 72 + 36 = 252 dollars ( in total )

Molar mass of FeCl3, Co(NO3)2, C4H10O, and Cu(NO3)2? Show work.

N76 [4]

Molar mass of FeCl₃ 162.204 g/mol

Molar mass of C₄H₁₀O is 74.1212 g/mol

Molar mass of Cu(NO₃)₂ is 187.5594 g/mol

Step-by-step explanation:

Molar mass is also termed as molecular mass of the compound. So it is the measure of the amount of mass present in the given molecule. It can be obtained by adding the products of number of atoms with their molecular mass.

For example, in order to find the molar mass of FeCl₃, the molecular mass of Fe is noted as 55.845 g/mol and the molecular mass of Cl is noted as 35.453 g/mol.

As FeCl₃ contains one atom of Fe and 3 atoms of Cl, then the

Molar mass = (Number of Fe atoms × Molecular mass of Fe) + ( Number of Cl atoms × Molecular mass of Cl)

Molar mass of FeCl₃ = (1×55.845)+(3×35.453)=162.204 g/mol.

Similarly, the molar mass of C₄H₁₀O will be

Molar mass = (4×Mass of C) + (10×Mass of H) + (1 × Mass of O)

Molar mass = (4×12.0107)+(10×1.00784)+(1×16)=74.1212 g/mol

Then the molar mass of Cu(NO₃)₂ will be

Molar mass = (1× Mass of Cu) + (2×Mass of N)+(6×Mas of Oxygen)

Molar mass = (1×63.546)+(2×14.0067)+(6×16)

Molar mass = 187.5594 g/mol
