Answer: its a little blurry not to be rood :c

Step-by-step explanation:

Answer: 14 days

Step-by-step explanation:

Day 1: 1 minute snooze = 24 minutes

Day 2: 2 minute nooze = 23 minutes ; these examples show snooze time = days.

We can set up an equation for this situation: 25 - s = r ; where s = snooze time and r = time to get ready.

Given the problem, we can fill out this equation with: 25 - s = 11

When you solve this equation, time snoozed = 14.

We already know that snooze time = days, so days = 14.

Answer:

d=  -32

Step-by-step explanation:

d/4+3=-5

d/4=-8

d=4 x (-8)

d= -32

Answer:

b=1

Step-by-step explanation:

2b+1+2b=3b+2b

4b+1=5b(Simplify both sides of the equation)

4b+1−5b=5b−5b(Subtract 5b from both sides)

−b+1=0

−b+1−1=0−1(Subtract 1 from both sides)

−b=−1

−b

−1

=

−1

−1

(Divide both sides by -1)

b=1

Answer:

Substitute your answer for the variable x. If the equation looks accurate or is correct, then the value of x is the right answer. Not sure if this makes sense

Determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Simplify the equation as much as possible using algebraic manipulations such as combining like terms, factoring, and expanding.

Evaluate the equation for a few different values of x to see if it holds true. If the equation is true for all values of x within the domain, then it will be true for all values of x. If there are any values of x within the domain that make the equation false, then it will be false for no values of x.

If the equation cannot be simplified or the domain cannot be determined, then it may require further analysis, such as graphing or using calculus techniques to determine its behavior.

Thus, determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.

Answer:

B

Step-by-step explanation:

The formula for a area of the first semi circle is

[tex] \frac{1}{2} \times \pi {r}^{2} [/tex]

where r is the radius

Since 4 is the diameter, 2 is the radius

plug it in

[tex] \frac{1}{2} \times \pi {2}^{2} [/tex]

[tex] \frac{1}{2} \times 4\pi[/tex]

[tex]2\pi[/tex]

so the area of the first circle is 2

[tex]2\pi[/tex]

now let find the second circle

Since the semi circle is twice the area of AB the diameter is 8 so the radius is 4.

Put it in the equation.

[tex] \frac{1}{2} \times \pi {4}^{2} [/tex]

[tex] \frac{1}{2} \times \pi \times 16[/tex]

[tex]8\pi[/tex]

Now let find the third circle

Since it is twice the size of the second circle, the diameter is 16 and the radius is 8.

[tex] \frac{1}{2} \times \pi {8}^{2} [/tex]

[tex] \frac{1}{2} \times 64\pi[/tex]

[tex]32\pi[/tex]

Now let add the area of the semi circle

[tex]32\pi + 2\pi + 8\pi = 42\pi[/tex]

Answer:

The x = 130°

Because it is corresponding

Answer:

m<UTV = 100°

Step-by-step explanation:

360 = 140 + 120 + m

360 = 260 + m

360 - 260 = 260 - 260 + m

100 = m

----------------------------------------

360 = 140 + 120 + 100

360 = 260 + 100

360 = 360

Answer:

16.97km

Step-by-step explanation:

To get the displacement, we will use the pythagoras theorem

Sum of distances along the horizontal (east and west) is expressed as

dx = 10 - 4 + 6

dx = 6+6

dx = 12km

Sum of distances along the y;

dy = 2 - 13 - 1

dy = -11-1

dy = -12km

Find the displacement using the pythagoras theorem

D = √(12)²+(-12)²

D = √144+144

D = √288

D = 16.97km

Hence her displacement is 16.97km

Answer:

55% is the answer to the question cause its 1500

Answer:

55% because its 1500

Step-by-step explanation:

Answer: 66%

Step-by-step explanation:

Wanda buys the boards at $50 and sells them as $83.

The markup in actual dollar amounts is:

= 83 - 50

= $33

In percentage terms, the denominator will be the cost price:

= Markup / Cost price * 100%

= 33 / 50 * 100%

= 66%
