6) Evaluate 2xy - 5 , for x= -3 and y=4
Your answer

Answer:

63.4

Step-by-step explanation:

Tan = opposite/adjacent

Tan x = tan-1

Tan-1 (6/12)

=63.43494882

63.4

She completed 65% so she has 35% more to go. ( 100% - 65% = 35%)

Multiply the length of the race by the percentage left:

40 x 0.35 = 14

She has 14 miles left.

The answer is B. 14 miles

Answer:

7 pizzas

Step-by-step explanation:

18 people × 3 slices each = 54 slices

54 ÷ 8 = 6.75

7 pizzas

Answer:

They should order 7 pizzas.

Step-by-step explanation:

18 people x 3 slices per person = 54 slices you will need for everyone

54 slices divided by 8 = 6.75 pizzas.

Round 6.75 to 7 pizzas.

They should order 7 pizzas because you cannot ask the pizza place for 6.75 pizzas.

Answer:

0.29

Step-by-step explanation:

14/25 * 4 = 56/100

                    |

                   \ /

                   56

56 + 15 = 71

100 - 71 = 29

29% = 0.29

Answer: $700

Step-by-step explanation:

The store is selling at 30% off.

If a mattress is $1,000, first find out what 30% of $1,000 is:

= 1,000 * 30%

= $300

The store is selling 30% off, this means that they are reducing the price by 30%:

= 1,000 - 300

= $700

Answer:

in 5 weeks i think

Step-by-step explanation

I added 300+20 5 times. Same with the 250

Answer:

5

Step-by-step explanation:

to vick = W1 = 300 + 20 x    (  1 )

to anya = W2 = 250 + 30 x    ( 2)           Both 1 and 2 ( simulataneous )

When W1 =  W2

300 + 20 x = 250 + 30 x

          10 x   = 5

  so they need 5 months

Answer:

c:88

Step-by-step explanation:

The angle that measures 92 degrees and the angle with the question mark are supplementary angles which mean their sums make up 180 degrees because they are on a line. So 180 degrees - 92 degrees = 88 degrees.

Answer:

105.6 ft

Step-by-step explanation:

The perimeter of a shape is just the lengths of its sides added up. Since a square has 4 equal sides, and a side is 26.4, the answer is 26.4 * 4 = 105.6 ft

Answer:

x > - 2

Step-by-step explanation:

3x + 9 < 3

3x (+ 9 - 9) < 3 - 9

3x < -6

3x/3 < -6/3

x > -2 (dividing by negative numbers, you reverse the inequality sign at the end of an equation)

Answer:

That's easy! All you have to do is multiply the three numbers.

A = L * W * H

A = 25 * 14 * 19

A = 6650in²

Step-by-step explanation:If h = 19 inches, l = 25 inches, and w = 14 inches, what is the area of the figure shown above?

A.

587.5 square inches

B.

608 square inches

C.

825 square inches

D.

276.5 square inches

Answer:

Ratio of goat to total number of animals at the zoo = 2 : 5

Step-by-step explanation:

Chickens = 2

Deer = 4

Donkeys = 3

Goats = 6

Total animals at the zoo = 15

what is the ratio of goats to the total number of animals at the zoo?

Ratio of goat to total number of animals at the zoo = 6 : 15

= 6/15

= 2/5

Ratio of goat to total number of animals at the zoo = 2 : 5

Answer:

123456762123456787654321`4567898

Step-by-step explanation:

Answer:

Question 1: ∠3 and ∠7 are corresponding angles.

Question 2: ∠2 and ∠8 are alternate interior angles.

Question 3: ∠4 and ∠6 are alternate exterior angles.

Question 4: ∠2 is congruent to ∠6.

Question 5: ∠8 is not congruent to ∠1.

Question 6: If ∠2 measures 132°, the measure of ∠7 would be 48°.

Answer:

x=7

Step-by-step explanation:

180=25x+5

175=25x

7=x

Answer:

x = 7

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

We know that,

→ Sum of all angles in a line is 180°.

Forming the equation,

→ (13x + 2) + (12x + 3) = 180°

Then the value of x will be,

→ (13x + 2) + (12x + 3) = 180°

→ 13x + 2 + 12x + 3 = 180°

→ (13x + 12x) + (2 + 3) = 180°

→ 25x + 5 = 180°

→ 25x = 180 - 5

→ 25x = 175

→ x = 175/25

→ [ x = 7 ]

Hence, the value of x is 7.

Answer:

36

Step-by-step explanation:

f(x)=2x^2

f(-3)=2(-3)^2

f(-3)= -6^2

f(-3)=36

Answer:

Step-by-step explanation:

f(x) = 2 x^2

f(-3) means that wherever there is an x on the right, put in - 3

f(-3) = 2 (-3)^2  

(-3)^2 = 9

f(-3) = 2 * 9

f(-3) = 18
