what is the aswer

Answers

Answer 1

Hey there!

“-1/5x ≤ 8”

MULTIPLY both sides by -5

-1/5x × -5 ≤ 8 × 5

CANCEL out: -1/5 × -5 because that gives you 1

KEEP: 8 × 5 because that helps us solve for your given equation

NEW EQUATION: x ≥ 8 × 5

8 × 5 = 40

Answer: x ≥ 40

Hal is downloading a file from the internet. So far he has downloaded 25% of the file.

If 10 minutes have passed since he started, how long will it take to download the rest of the file?

Answers

Answer:

30 minutes

Step-by-step explanation:

If it takes 10 minutes to download 25%, and there is 75% left to reach 100%.

25% + 25% +25% = 75% there are 3 25% left thus,

10min + 10min + 10min = 30 minutes left to complete download.

The amount of time in minutes it will take to download the rest of the file

is 30 minutes.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Let, 'x' be the number of minutes required to download the complete movie.

Therefore,

25% of 'x' is 10 minutes, This can be numerically expressed as,

(25/100)×x = 10.

0.25x = 10.

x = 10/0.25.

x = 40 minutes.

So, it would take 40 10 = 30 minutes.

Lily, Juliet, and Willow are baking muffins. Lily has 1 1/2 cups of flour, Juliet has 3/4 cup of flour, and Willow has 1 2/6 cups of flour. How many cups of flour do they have altogether?

Answers

Answer: 3 7/12

Step-by-step explanation:

From the question, we are given the information that Lily has 1 1/2 cups of flour, Juliet has 3/4 cup of flour, and Willow has 1 2/6 cups of flour.

The number of cups of flour that they have altogether would be the addition of all the fractions of each girl. This would be:

= 1 1/2 + 3/4 + 1 2/6

The lowest common multiple is 12, therefore we make them have a common denominator

= 1 6/12 + 9/12 + 1 4/12

= 2 19/12

= 2 + 1 7/12

= 3 7/12 cups

A. X = 3, y = 2
B. X = 6, y = 0
C. Infinitely many solutions
D. No solution

Answers

Answer:

Step-by-step explanation:

If you rewrite the questions into linear form (y=mx+b) then you get

For the first one

2x-12= -3y

Divide by -3 and get

-2/3x +4 =y

For the second one

-6y=4x -24

Divide by -6 and get

y= -4/6x +4

Simplify the fraction and you get -2/3x+4 =y

Obviously these two lines are identical meaning that any number will work

the answer should b c infinitely many solutions

independent practice: tangents of circles

Find the value of x in each of the following:
(see picture)

Answers

Answer:

Step-by-step explanation:

9). "Tangent is perpendicular to the radius of a circle"

By applying Pythagoras theorem in the given triangle,

x² = 15² + 20²

x = √625 = 25

10). By applying Pythagoras theorem in the given triangle,

(r + x)² = r² + 15²

(8 + x)² = 8² + 225

8² + x² + 16x = 8² + 225

x² + 16x = 225

x² + 16x - 225 = 0

x² + 25x - 9x - 225 = 0

x(x + 25) - 9(x + 25) = 0

(x + 25)(x - 9) = 0

x = -25, 9

But x > 0

Therefore, x = 9 is the answer.

11). By the property of the tangents drawn to the circle from a point,

"Tangents drawn from a point lying outside the circle are equal in measure"

AC = BC

3x + 4 = 40

3x = 36

x = 12

12). By the same property used in question (11)

DE = DC = 4 units

BA = BC = 3 units

x = 4 + 3 = 7 units

Answers

Answer:

3 months

Step-by-step explanation:

So 60 dollar down and 70 per month

130 (60+70)

200

270

now 90 per month but no down

180

270

So 3 months

The number of months will be 3 is it until your cost is the same as Mega-er-Gym. The correct option is B.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Mega-Gym costs a one-time $60 membership fee and then charges $70 per month, while Mega-er-Gym does not charge a membership fee but costs $90 per month.

Cost of Megagym = 60 + 70m

Cost of Mega-er-Gym = 90m

90m = 60+70m

20m = 60

m = 60 / 20

m = 3 months

OPTIONS: 0.4 0.625 0.8 1.25 5.44 6.25 12.5 25

Answers

Answer:

1.-t₁ = 0,625 s

2.-h(max) = 6,25 f

3.-t = 1,25 s

Step-by-step explanation:

V₀ = 20 f/s

h(t) = - 16*t² + 20*t

h(max) = ??

h´(t) = - 32*t + 20

h(max) will occurs when V = 0 dh/dt = 0 then

- 32*t + 20 = 0

- 32*t = -20

t = 20/32

t₁ = 0,625 s

h(max) = h(0,625) = - 16*(0,625)² + 20*0,625

h(max) = - 6,25 + 12,5

h(max) = 6,25 f

c) The ball will hit the ground

t = 2*t₁

t = 2*0,625

t = 1,25 s

An air traffic controller is tracking two planes. To start, Plane A was at an altitude of890 meters, and Plane B was at an altitude of1322 meters. Plane A is losing altitude at 16 meters per second, and Plane B is losing altitude at25 meters per second.

Answers

Equation to show when they'll both be at the same altitude

Answer:

890 - 16x ; 1322 - 25x ; 9x = 432 = x = 48

Step-by-step explanation:

Plane A:

Altitude = 890 m

Altitude loss = 16 m per second

Plane A:

Altitude = 1322 m

Altitude loss = 25 m per second

Equation :

Altitude - (altitude loss * time)

Plane A:

890 - 16x

Plane B:

1322 - 25x

Plane A = Plane B

890 - 16x = 1322 - 25x

-16x + 25x = 1322 - 890

9x = 432

x = 432 / 9

x = 48 seconds

Sneakers at Mr. Lou's garage sale cost the same price. Alexander paid $90.52 for four pairs. How many pairs of sneakers did Justin buy if he paid $135.78? Write a proportion and use cross products to solve for d, the number of sneakers that David bought

Answers

Answer:

6 pairs

Step-by-step explanation:

Since we are given a ratio/proportion problem and 3 values and 1 variable then we can use the Rule of three to solve this problem. We simply multiply the diagonal values available and divide by the 3 value to find the variable of the ratio like so...

4 pairs <======> $90.52

d pairs <======> $135.78

(4 * 135.78) / 90.52 = 6 pairs

Finally, we can see that Justin ended up buying a total of 6 pairs of sneakers.
