Answer:

2 Cups

Step-by-step explanation:

First of all you need to add all of the ingredients together, which would total 12 cups of smoothie. Also important to add is that 1 quart is 4 cups. Then you have 12/6 which equals 2!

The cups of smoothie in each glass is 2 cups.

In order to determine the number of cups of smoothie that would be put in each glass, it should be ensured that the measures of the ingredients are in the same unit.

The first step is to determine the total cups of smoothie that Craig makes.

In order to determine the total cups, quart has to be converted to cups

1 quart = 4 cups

Total number of cups = 5 + 4 + 3 = 12 cups

The next step is to determine the cups in each glass.

Cup of smoothie in each glass = total number of cups of smoothie / total number of large cups

12 / 6 =2 cups.

Answer:

Solution: x = 9    Extraneous solution:  x = 1

Step-by-step explanation:

Given equation:

[tex]\sqrt{4x}=x-3[/tex]

Square both sides:

[tex]\implies \left(\sqrt{4x}\right)^2=\left(x-3\right)^2[/tex]

[tex]\implies 4x=x^2-6x+9[/tex]

Subtract 4x from both sides:

[tex]\implies 4x-4x=x^2-6x+9-4x[/tex]

[tex]\implies 0=x^2-10x+9[/tex]

[tex]\implies x^2-10x+9=0[/tex]

Split the term in x:

[tex]\implies x^2-x-9x+9=0[/tex]

Factor the first two terms and the last two terms separately:

[tex]\implies x(x-1)-9(x-1)=0[/tex]

Factor out the common term (x - 1):

[tex]\implies (x-9)(x-1)=0[/tex]

Apply the zero-product property:

[tex](x-9)=0 \implies x = 9[/tex]

[tex](x-1)=0 \implies x=1[/tex]

Substitute the found values of x into the original equation to verify the solutions:

[tex]\begin{aligned}x=9 \implies \sqrt{4 \cdot 9} & = 9-3\\\sqrt{36} & = 6\\6 & = 6\end{aligned}[/tex]

[tex]\begin{aligned}x=1 \implies \sqrt{4 \cdot 1} & = 1-3\\\sqrt{4} & = -2\\ 2 & = -2\end{aligned}[/tex]

Therefore, the only valid solution is x = 9:

Extraneous solution:  A solution from the process of solving the equation that is not a valid solution to the original equation.

Answer:

Step-by-step explanation:

1) The angular speed is approximately 12.566 radians per second.  

2) The linear speed of a point on the edge of the disk is 1.257 meters per second.

1) Herein we have a disk that spins at constant angular speed (ω), in radians per second, whose magnitude is found dimensional analysis and unit conversions:

ω = 120 rev / min × (2π rad / 1 rev) × (1 min / 60 s)

ω ≈ 12.566 rad / s

The angular speed is approximately 12.566 radians per second.  

2) The linear speed (v), in meters per second, on the edge of the disk is described by the following formula:

v = R · ω  

Where R is the radius of the spinning disk, in meters.

If we know that R = 0.1 m and ω ≈ 12.566 rad / s, then the linear speed is:

v = (0.1 m) · (12.566 rad / s)

v = 1.257 m / s

The linear speed of a point on the edge of the disk is 1.257 meters per second.

Answer:

If you could take a picture of the rectangle I could help you answer that. I can't see the rectangle.

Answer:

15, 16 and 17

Step-by-step explanation:

Consecutive numbers mean numbers that are separated by 1 from each other. For example 5, 6 and 7 are three consecutive numbers and 5 is the smallest

Let the smallest number be x
Then the next consecutive number is x + 1  
The next one after that is x + 2

Sum = x + x + 1 + x + 2 = x + x + x + 1 + 2 = 3x + 3

We are told that this sum is 33 more than the smallest number x

So 3x+3 = x + 33 Subtract x from both sides
3x - x + 3 = x + 33 -x
==>  2x + 3 = 33

Subtract 3 from both sides
==> 2x + 3 - 3 = 33 -3
==> 2x = 30
Divide both sides by 2

==> 2x/2 = 30/2
==> x = 15

So the smallest number is 15 and the three numbers are 15, 16 and 17

Verify by adding 15+16 +17 = 48
15 + 33 = 48 so consistent

A: The three consecutive numbers are 15, 16, 17.

Explanation:

Let x, y, z be the numbers.

x + y + z = x + 33

y = x + 1

z = x + 2

We will solve this system of equations using the substitution method.

x + x + 1 + x + 2 = x + 33

x + x + x - x = 33 - 1 - 2

2x = 30

x = 15

y = 15 + 1 = 16

z = 15 + 2 = 17

Solving for x + y + z = x + 33:

15 + 16 + 17 = 15 + 33

48 = 48

A: 15, 16, 17.

By using a linear equation, we can see that after the 19 day the population will be less than 1000 mold spores.

We know that the population decays at a rate of 30 spores per day, and we have an initial population of 1560 mold spores.

Then, the population of spores after x days is given by the linear equation:

P(x) = 1560 - 30*x

The population will be exactly 1000 spores when:

P(x) = 1000 =  1560 - 30*x

We need to solve that for x.

30x = 1560 - 1000 = 560

x = 560/30 = 18.67

So after 18.67 days the population is 1000, this means that after the 19 day the population will be less than 1000 mold spores.

What is the formula for rate and distance?

Use the formula d = st to determine speed, distance, or time. Distance is equal to speed multiplied by time. Given two known numbers, the Speed Distance Time Calculator can solve for the unknown sdt value.

Units of seconds (s), minutes (min), hours (hr), or hours, minutes, and seconds can be used to input or solve for time (hh:mm:ss). Time format shortcuts are shown below.

Use the formula d = st, or distance equals speed times time, to find the distance.

Distance Equals speed x time

Since both reflect a certain amount of distance per unit of time, such as miles per hour or kilometers per hour, rate and speed are comparable. If speed s and rate r are equal, then r = s = d/t. The corresponding formula is d = rt, which denotes Rate times time are equivalent to distance.

Distance = Rate x Time

Use the speed formula, s = d/t, which states that speed is equal to distance divided by time, to solve for speed or rate.

speed equals distance/time.

Use the time formula, t = d/s, which states that time is equal to distance divided by speed, to solve for time.

Time = Speed/Distance

Answer:

126

Step-by-step explanation:

A number is divisible by 3 if its sum of digits is divisible by 3 (you can do it over and over again until it's one digit!).

A number is divisible by 2 if its last digit is 0, 2, 4, 6 or 8.

A number is divisible by 6 if it is divisible by 2 and by 3.

A number is divisible by 9 if its sum of digits is divisible by 9 (you can do it over and over again until it's one digit!).

So we need a number with last digit 0, 2, 4, 6, or 8 (because it's divisible by 6 hence by 2) and with a sum of digits divisible by 9 (because if it's divisible by 9 it's also divisible by 3).

130 is not divisible by 9, so the first digits must be 12X.

to get a number divisible by 9, we need to add a digit D so that 1+2+D is divisible by 9.

9 - 1 - 2 = 6

126 is divisible by 9 because it's sum of digits is 9. It's also divisible by 6, because it is divisible by 3 and its last digit is 6.

They will weigh the same at twenty-five months.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Let the number of months when they will weigh the same would be m

Given that Bill is losing two pounds per month and is currently 240 pounds.

So his model expression of weight would be: 240 - 2m

And Bill is losing four pounds per month and is currently 290 pounds.

So his model expression of weight would be: 290 - 4m

As per the condition, they will weigh the same

⇒ 240 - 2m = 290 - 4m

⇒ 4m - 2m = 290 - 240

⇒ 2m = 50

⇒ m = 25

Therefore, they will weigh the same at twenty-five months.

false is the answer of that Q

To solve this problem we need to be aware of the concepts of angles in a circle. Also we need to know what is a major angle and what is a minor angle.

That major part of an angle is equal to (360-minor part of the angle).

We know the total angle in a circle is 360°.

Here, ∠SKL=120+2x; ∠JKS=28° and ∠JKL=x+148.

Sum of all the angles will give us 360°.

According to question,

  ∠SKL+∠JKS+∠JKL=360°

⇒(120+2x)°+28°+(x+148)°=360°

⇒3x+296°=360°
