Answer:

right triangle

Step-by-step explanation:

We know that the total angles of the triangle are 180 degrees:

(x) + (4x-10) + (2x+15) = 180

7x - 10 + 15 =180

7x + 5 = 180

7x = 180 - 5

7x = 175

x = 175÷ 5 = 25

Now we calculate each angle

x=25

4x-10= (4*25) -10=100-10=90

2x+15=(2*25)+15=50+15=65

Because we have a right angle, then the triangle is right triangle

a computer and printer a totoal cost $1132 the cost of the computer is three times the cost of the ptinter

zavuch27 [327]

Use a system of equations

C+P=1132
3P=C

Substitute C in first equation as
3P+P=1132
Simplify
4P=1132
Solve
P=1132/4
P=283

NOW SOLVE FOR C SUBSTITUTING P VALUE IN FIRST EQUATION

C+283=1132
C=1132-283
C=849

Printer = 283$
Computer = 849$

Using the letters in the word INNOVATIVE, find the number of permutations that can be formed using 4 letters at a time. Show you

lyudmila [28]

Answer: 1) 5040 and 2) 165

Step-by-step explanation:

1) Here total number of letters = 10

The number of permutations that can be formed using 4 letters at a time

= P (10, 4)

= $10_P_4$

= $\frac{10!}{(10-4)!}$

= $\frac{10!}{6!}$

= $\frac{10\times 9\times 8\times 7\times 6!}{6!}$

= 10 × 9 × 8 × 7

= 5040

2) Here the total number of machine = 11

The different combinations of machines can Geoff choose from to use

= $11_C_3$

= $\frac{11!}{(11-3)!3!}$

= $\frac{11!}{8!3!}$

= $\frac{11\times 10\times 9\times 8!}{8!\times 6}$

= 11 × 5 × 3

= 165
