four-fifths of a number minus two is greater than three-tenths of twice that number

Answers

Answer 1

If you can write this out, it will read
(4/5)x-2>(3/10) times 2x
Now, lets combine what we can, and then add 2 to both sides,
((4/5)x>(3/5)x+2
Now divide both sides by (4/5), or multiply both sides by (5/4).
x>12x+(2 times (5/4))

The amount of rhubarb in the original recipe is 31\2 cups. Using what you know of whole numbers and what you know of fractions, explain how you could triple that mixed number

Answers

31/2 x 3/1 = 93/2 = 46 1/2

To triple a mixed number, multiply the whole number part by 3 and triple the numerator of the fraction part. For 3 1/2, the result is 9 3/2.

To triple the mixed number 3 1/2:

Multiply the whole number by 3: 3 x 3 = 9.

For the fraction part, triple the numerator: 1 x 3 = 3. The denominator remains the same.

Therefore, tripling 3 1/2 gives 9 3/2.

In the first half (distance) of a trip, a truck travels at a speed of 70 km/hr. How fast must it go during the second half of the trip to average 80 km/hr for the entire trip? km/hr

Answers

Final answer:

To average 80 km/hr for the entire trip, the truck must go at a speed of 80 km/hr during the second half of the trip.

Explanation:

To find out how fast the truck must go during the second half of the trip to average 80 km/hr for the entire trip, we can use the concept of average speed. Average speed is calculated by dividing the total distance traveled by the total time taken.

Let's assume the entire trip is made up of two equal halves. In the first half, the truck travels at a speed of 70 km/hr. So, if we consider the distance traveled in the first half to be 'd', the distance traveled in the second half will also be 'd'.

Therefore, the total distance traveled for the entire trip is 2d. Now, to average 80 km/hr for the entire trip, we can use the formula:Average speed = Total distance / Total time

80 km/hr = 2d / Total time

Since the time taken for the first half is the same as the time taken for the second half, we can represent the total time as '2t', where 't' is the time taken for each half.

Substituting the values, we have:80 km/hr = 2d / (2t)

Cancelling out the common factors, we get:80 = d / t

Since the distance traveled in the first half is 'd' and the time taken for the first half is 't', the speed during the second half must be '80' km/hr to average 80 km/hr for the entire trip.

B) there is a line with positive slope that is tangent to both circles. find the equation of this line, and (c) determine the points at which this tangent line touches each circle

Answers

Given that there is a line with positive slope that is tangent to both circles [tex]x^2 + y^2 = 1[/tex] and [tex](x-3)^2 + y^2 = 4[/tex].

Let the point of tangency in the first circle be (a, b) and the point of tangency in the second circle be (c, d), then the slope of the tangent to the first circle is given by

[tex]2x+\left.2y \frac{dy}{dx}\right|_{(a, b)} =0 \\ \\ \Rightarrow \left.\frac{dy}{dx}\right|_{(a, b)} =- \frac{x}{y} =- \frac{a}{b} [/tex]

and the slope of the second circle is given by

[tex]2(x-3)+\left.2y \frac{dy}{dx}\right|_{(c, d)} =0 \\ \\ \Rightarrow \left.\frac{dy}{dx}\right|_{(a, b)} =- \frac{x-3}{y} =- \frac{c-3}{d}[/tex]

From the first circle equation, we have

[tex]x^2 = 1 - y^2 \\ \\ \Rightarrow a^2 = 1 - b^2[/tex]

and from the second equation, we have

[tex](x-3)^2 = 4 - y^2 \\ \\ (c-3)^2 = 4 - d^2[/tex]

Since the two slopes above are for the same line, then

[tex] \frac{a}{b}= \frac{c-3}{d} \\ \\ \Rightarrow ad=b(c-3) \\ \\ \Rightarrow a^2d^2=b^2(c-3)^2 \\ \\ \Rightarrow(1-b^2)d^2=b^2(4-d^2) \\ \\ \Rightarrow d^2-b^2d^2=4b^2-b^2d^2 \\ \\ \Rightarrow d^2=4b^2 \\ \\ \Rightarrow d=\pm2b[/tex]

Thus, we have

[tex] \frac{a}{b}= \frac{c-3}{2b} \\ \\ \Rightarrow a= \frac{c-3}{2} [/tex]

Answers

Okay. So Rose and Gabby sold 69 boxes of cookies together and Gabby sold 35 of them. To find the amount Rose sold, let's set up an equation. 35 + b = 69. Let's subtract 35 from both sides. When you do that, you get that b = 34. Rose sold 34 boxes of cookies for their soccer team fundraiser.

To find area, you multiply length * width. There are 4 sides on a number, so we need to have a equation like this. x * x * y * y = 12cm. If we do 4 * 4, we get 8. We could also use 2 * 2 = 4. 8 + 4 = 12. So, width = 8, and length = 4.

What is the correct order of the following numbers? -17/10, -2, -(1.2)2

Answers

-(1.2)2 , -2 , -17/10

Answer:

The correct order from least to greatest is: [tex]$-2$, $-1.7$, $-1.44$.[/tex]

Explanation:

To determine the correct order of the given numbers, let's first simplify them:

1. [tex]$-\frac{17}{10}$[/tex] is equivalent to [tex]$-1.7$.[/tex]

2. [tex]$-2$[/tex] remains as is.

3. [tex]$-(1.2)^2 = -1.44$, as $1.2^2 = 1.44$[/tex] and the negative sign is applied.

Now, we have:

1. [tex]$-1.7$[/tex]

2. [tex]$-2$[/tex]

3. [tex]$-1.44$[/tex]

So, the correct order from least to greatest is: [tex]$-2$, $-1.7$, $-1.44$.[/tex]

The formula f 5280m can be used to convert a measurement of f feet to an equivalent measurement of m miles. If an airplane flies at 21,120 feet above the ground, how much is that in miles?

Answers

Just to help you, that formula is saying that 1 mile is equivalent to 5280 feet, i.e. the number of feet is equal to 5280 * number of miles.

So, you know the number of feet = 21,120 and have to convert that into the equivalent number of miles:

f = 5280m => m = f / 5280

m = 21,120 / 5280 = 4 miles

Answer: 4 miles

Just multiply them both

Answer:

The diver's new depth is -42 ft.

Step-by-step explanation:

Given : A scuba diver at a depth of -12 ft (12 ft below sea level), dives down to a coral reef that is 3.5 times the diver's original depth.

To find : What is the diver's new depth?

Solution :

A scuba diver at a depth of -12 ft.

Dives down to a coral reef that is 3.5 times the diver's original depth.

So, We have to multiply the original depth by 3.5.

[tex]d=-42[/tex]

Therefore, the diver's new depth is -42 ft.

a cleaning service order 7 large bottles and 5 small bottles of cleaning products each large bottle has 122 Oz each small bottle has 68 Oz which is the best estimate of the total amount of cleaning products that cleaning service orders

Answers

Final answer:

The best estimate of the total amount of cleaning products that the cleaning service orders is 1,194 Oz.

Explanation:

To find the best estimate of the total amount of cleaning products that the cleaning service orders, we need to calculate the total amount of cleaning products in the large bottles and small bottles separately and then add them together.

Each large bottle has 122 Oz, and the cleaning service orders 7 of them. So the total amount of cleaning products in the large bottles is 7 x 122 = 854 Oz.

Each small bottle has 68 Oz, and the cleaning service orders 5 of them. So the total amount of cleaning products in the small bottles is 5 x 68 = 340 Oz.

To get the best estimate of the total amount of cleaning products, we add the amounts in the large bottles and small bottles together: 854 + 340 = 1,194 Oz.

False, because you can be a 13, 15, 16,17, 18 year old teenager.

Final answer:

The converse of the conditional statement "If you are 14 years old then you are a teenager" is true. If someone is a teenager, it implies that they are at least 14 years old.

The converse of the conditional statement "If you are 14 years old then you are a teenager" is:

If you are a teenager then you are 14 years old.

The converse statement is true because if someone is a teenager, it implies that they are at least 14 years old. However, it does not guarantee that someone who is 14 years old is necessarily a teenager, as there are other age groups within the teenage years.
