Answer:

147

Step-by-step explanation:

In a triangle, the 3 angles all add up to 180 to get x you must add 10 and 23 which you will get 33. Lastly, you must subtract 180-33 which gets your answer of 147, hope this helped!

Answer: Answer is 4.25

Step-by-step explanation: Jus take you first number (2 over 8.50) and divide. You get 4.25. Now try to multiply or add for other numbers, and you find multiplying 4.25 by X will get you the answer of Y.

Answer:

angle e = 64

angle d =141

Step-by-step explanation:

for angle e

add 77 to 39 and you'll get 116

subtract 116 from 180

you'll get 64

angle e = 64

for angle d

subtract 39 from 180

and you'll get 141 which is the value of angle d

Let's solve ~

The given equations are :

[tex] \qquad \dashrightarrow \bf \: 3x + 4y = 36 \sf \: \: \: \: \: \: \: \: \: \: (1)[/tex]

and

[tex] \qquad \dashrightarrow \sf \:y = - \frac{1}{2} x + 8[/tex]

[ multiply each sides by 2 ]

[tex] \qquad \dashrightarrow \sf \: 2y = - x + 16[/tex]

[tex] \qquad \dashrightarrow \sf \:x + 2y = 16[/tex]

[ multiply both sides by 2 ]

[tex] \qquad \dashrightarrow \bf \: 2x + 4y = 32 \: \: \: \: \: \: \: \: \: \: \: \sf(2)[/tex]

Now, subtract equation (2) from (1)

[tex] \qquad \dashrightarrow \sf \: 3x + 4y - (2x + 4y) = 36 - 32[/tex]

[tex] \qquad \dashrightarrow \sf \: 3x + \cancel{4y }- 2x - \cancel{4y }= 4[/tex]

[tex] \qquad \dashrightarrow \bf \: x = 4[/tex]

Now, as we got the value of x, let's solve for y :

[tex] \qquad \dashrightarrow \sf \: y = - \dfrac{1}{2} x+ 8[/tex]

[tex] \qquad \dashrightarrow \sf \: y = -\dfrac{1}{2} (4)+8[/tex]

[tex] \qquad \dashrightarrow \sf \: y = - 2 + 8[/tex]

[tex] \qquad \dashrightarrow \bf \: y = 6[/tex]

Answer:

Obtuse angle

Step-by-step explanation:

If a measurement of an angle is more than 90, then it is obtuse angle

Answer:

Obtuse angle (second option)

Step-by-step explanation

Since m∠FOR = 150°, its measurement is greater than (>) 90° & less than (<) 180°. Hence, it's an obtuse angle.

< 90° =》acute angle

= 90° =》 right angle

> 90° =》 obtuse angle

= 180° =》 straight angle

I hope this helps you

:)

Answer:

The distance between the pair of numbers is the absolute value of [tex]a[/tex], or [tex]|a|[/tex].

Step-by-step explanation:

Use the distance formula: [tex]d=|x_2-x_1|[/tex]. The [tex]x[/tex]s represent points one and two. Point one is [tex]-a[/tex], and point two is 0. Plug these into the equation, then solve:

[tex]d=|x_2-x_1|\\d=|(0)-(-a)|\\d=|a|[/tex]

Therefore, the distance between the pair of numbers is the absolute value of [tex]a[/tex], or [tex]|a|[/tex].

Answer:

80 + 9x + 4 + 16x - 4 =180

25x = 180 - 80 + 4 - 4

25x = 100

x = 4

Answer:

$24

Step-by-step explanation:

cost of a pass for a week (without equipment rental) = 7 x 25 = $175

Therefore, cost of just renting the equipment for the week = 199 - 175 = $24

ETA: As an algebraic equation

Let x = number of days

Let y = cost of renting the equipment for a week

y = 199 - 25x

Step-by-step explanation:

The americium is represented as 1. Every 432 years it decreases by 50%.

First half-life:

432 years.

[tex]1 \div 2 = 0.50[/tex]

0.50 (1/2) of americium remains after 432 years.

Second half-life:

[tex]432 \times 2 = 864[/tex]

[tex]0.5 \div 2 = 0.25[/tex]

0.25 (1/4) of the americium remains.

Third half-life:

[tex]432 \times 3 = 1296[/tex]

[tex]0.25 \div 2 = 0.125[/tex]

0.125 (1/8) of the americium remains.

Last half-life:

[tex]432 \times 4 = 1728[/tex]

[tex]0.125 \div 2 = 0.0625[/tex]

0.0625 (1/16) of the americium remains.

Option B is correct.

Answer:

8

Step-by-step explanation:

10 percent of 80 is 8

80 x 0.1 = 8

4 is 16 percent of 25

25/4 = 0.16

0.16 = 16%

Answer:

Declare h. We can declare it as any number, so let's say 2.

h - 13 = 11 ↓

because h = 2.

Answer:

B

Step-by-step explanation:

there are 30 buildings...

15x + 17y = 31

17x + 15y = 21

- - -

───────

-2x + 2y = 10

→ -2 (x -y) = 10

→ x - y = -5

Value of (x - y) is -5

In this exercise we have to use the knowledge of equation to find the value, so:

[tex]x-y=-5[/tex]

The solution of a linear system is every ordered and finite set that satisfies all the equations of the system at the same time. The number of elements in the solution set is always equal to the number of unknowns in the system.

So we have:

[tex]15x + 17y = 31\\17x + 15y = 21\\-2x + 2y = 10\\-2 (x -y) = 10\\x - y = -5[/tex]

Hi There!

Given:

To Find:

How many placemats can Mandy make, if she has 200 ft of ribbon?

Solve:

200÷30≈7

Thus, she can make 7 placemats.

[tex]\huge\textbf{TheStarryNights}[/tex]

Answer:

C. 6 placemats

Step-by-step explanation:

Mindy has 200 feet of ribbon and each placemat requires 30 feet of ribbon.

Now, we need to divide 200 by 30.

200/30 ≈ 6.66666666667

Now, what whole number is before 6.66666666667?

6.

Now, what whole number is after 6.66666666667?

7.

What is 7 x 30?

210.

What is 6 x 30?

180.

Mindy has only 200 feet of ribbon, so she can't make 7 placements because 200 < 210, but she can make 6 placements because 200 > 180.

Answer:

h=78.4

Step-by-step explanation:

2/1.25 = h/49

Cross multiplication

1.25h = 2x49

1.25h=98

h= 78.4

                   CHECK:

         2/1.25 = 1.6

        78.4/49=1.6
