Two angles of a triangle measure 58° and 104°. What is the measure of the third angle of the triangle?

A triangle would measure up to 180 degrees
so 58 + 104 = 162
180 - 162 = 18
the third angle would be 18 degrees

Answer:

81x²+180x+100
9x²+180x+10²
using (a+b)²=a²+b²+2ab
9x²+2(9x)(10)+10²
(9x+2)²=(9x+2)(9x+2)

You have total coins for a total of $. . You only have quarters and dimes. Let represent the number of quarters and represent th

Sonja [21]

Answer:

$Quarters = 41$

$Dimes = 18$

Step-by-step explanation:

Given

$Coins = 59$

$Worth = \$12.05$

$d = dimes$

$q = quarters$

Required

The number of each coin

The total coins can be represented as:

$d + q = 59$

$1\ quarter = \$0.25 \\ 1\ dime = \$0.10$

So, the worth of the coin is:

$0.25q + 0.10d = 12.05$

The equations to solve are:

$0.25q + 0.10d = 12.05$

$d + q = 59$

Make d the subject in: $d + q = 59$

$d =59 - q$

Substitute $d =59 - q$ in $0.25q + 0.10d = 12.05$

$0.25q + 0.10(59 - q) = 12.05$

$0.25q + 5.9 - 0.10q = 12.05$

Collect like terms

$0.25q - 0.10q = 12.05 - 5.9$

$0.15q = 6.15$

Solve for q

$q=\frac{6.15}{0.15}$

$q=41$

Substitute $q=41$ in $d =59 - q$

$d = 59 - 41$

$d = 18$

So:

$Quarters = 41$

$Dimes = 18$

Tell whether the sequence is arithmetic. If it is, identify the common difference.

kiruha [24]

Answer:

Option A is correct not arithmetic

Explanation:

We have given terms $\frac{1}{2},{1}{3},{1}{4}$ these terms are not an arithmetic progression because

Arithmetic progression is the sequence of terms in which difference between successive and proceeding terms is same.

$d=a_2-a_1$

we can see the difference between $\frac{1}{3}$ and $\frac{1}{2}$ is $\frac{-1}{6}$

Whereas, the difference between $\frac{1}{4}$ and $\frac{1}{3}$ is $\frac{-1}{12}$ .
