Answer 1

Answer:

∡ a = 80°

Step-by-step explanation:

the sum of the interior angles of a triangle is 180 degrees

a + 30 + 70 = 180

a + 100 = 180

a = 80

Answer 2

Answer:

80 Degrees

Step-by-step explanation:

A triangle equals 180 degrees when all sides are added together, so here we need to first add the angles of the ones we have available.

30 + 70 = 100

Now, we subtract to find out how much more we need...

180 - 100 = 80

10^8/10^4 Simplify the expression. Write your answer as a power.

Answers

Answer:   10^4

This is an exponential expression with 10 as the base and 4 as the exponent.

=============================================

Explanation:

We're dividing 10^8 over 10^4. When dividing like this, we subtract the exponents (numerator minus denominator). The bases must be the same value and they stay at the same value for the final answer as well.

The new exponent is 8-4 = 4 which is how we arrive at the answer 10^4.

Side note: 10^4 = 10,000 = ten thousand

Answers

Answer:

C. 48x = 32

Step-by-step explanation:

For which equations does the fraction 2/3 make the equation true? Choose all that apply

Solving

A. 35x =20

x = 20/35

x = 4/7

B. 26x=18

x = 18/26

x = 9/13

C. 48x = 32

x = 32/48

x = 2/3

D. 22x =14

x = 14/22

x = 7/11

The correct Option is Option C

A card is randomly selected from a standard deck of 52 cards.what is the probability that it is a 10 or a face card?

Answers

Answer:

In a deck of cards, there are 6 faced cards. So, the probability of drawing a faced card is 6 out of 52 cards. Thus, the probability of drawing a face card from a deck of cards is 6/52 = 3/26.

more slope pls helpppppp

Answers

Answer:  C) 2

Explanation:

Recall that the general point-slope form is [tex]y - y_1 = m(x - x_1)[/tex] where m is the slope and [tex](x_1, y_1)[/tex] is the point the line goes through. We see that the 2 and the m match up, so m = 2 is the slope.

Side note: We can rewrite that given equation into y - (-5) = 2(x - (-1)) to see that the line goes through the point (-1, -5)

Answer:

C: 2

Step-by-step explanation:

y + 5 = 2x + 2 (distribute 2)

y = 2x -3 (subtract 5 from both sides)

2x means: slope times x

Fannie is making a rectangular blanket. The length of the blanket is 10 inches greater than its width, w, in inches. Write the function, f(w), that describes the area, in square inches, of Fannie's blanket as a function of the width, w

Answers

Answer:

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

It can be written as

f(w) =  (w+10) w.

Step-by-step explanation:

Let the width of the rectangular blanket be given by w and the length be given by l. According to the given condition length = 10+ width

Area of the rectangular blanket= length * width

A= l*w    ( as l= w+10)

A = (w+10) w

A= w²+ 10w

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

It can be written as

f(w) =  (w+10) w.

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

What is the area of a rectangle?

The area of the rectangle is the product of the length and width of a rectangle.

Area of rectangle = L × W

Let the width of the rectangular blanket be given as w and the length be given by l.

The length is given as 10 inches greater than its width

length = 10+ width

Area of the rectangular blanket= length × width

A= l × w    

also, A = (w+10) w

A= w²+ 10w

Therefore, the function f(w) = w²+ 10w gives the area of the rectangular blanket.
