which three of the following are correct

1/5 < 1/4
2/3= 5/9
1/3 = 2/6
3/4> 6/10
2/3 > 4/5

Answer:

The correct answers are 15 and 16.

Step-by-step explanation:

First we must assume the information.

We know that the total miles traveled is 617.3.

Every 41 miles, Karl spent 1 gallon of gas.

What we need to find out now is to estimate the total number of gallons of gas Karl used.

We will do it with the following equation:

If for 41 miles ------- 1 gallon

For 617.3 miles ------ x Gallon

41. x = 617.3 . 1

And we just have to clear the x:

X = 617.3 / 41

X = 15.05

Because they ask us for an approximate logic result, we can say that the correct options are 15 or 16 gallons of gas.

Answer:

45

Step-by-step explanation:

Area of a square = side²

Area of a rectangle = Length x Wide

The number of square brownies cut from the pan is 24 brownies.

A Square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is given as side².

We have,

Brownie dimensions:

Length = 18 inches

Wide = 12 inches

Area of a rectangle = Length x Wide

Area of the Brownie

= 18 x 12

= 216 square inches

The brownies are cut into squares:

Side = 3 inches

Area of the square brownies.

= 3 x 3

= 9 square inches

Now,

The number of squares with sides of 3 inches cut from the Brownie.

= Area of the brownies / Area of the square brownies

= 216 / 9

= 24

Thus,

The number of square brownies cut from the pan is 24 brownies.

Alyson needs 4 more beads so that she will be left with no remaining beads.

Alyson has 46 beads and each bracelet requires 5 beads. To find out how many more beads Alyson needs, we first divide the total number of beads she has by the number of beads per bracelet. This initial calculation is 46 divided by 5, which equals 9 with a remainder of 1. Since we cannot create a partial bracelet, we see that Alyson can make 9 complete bracelets with the beads she has, using up 45 beads (9 bracelets times 5 beads per bracelet). However, she is left with 1 bead.

To ensure there are no beads leftover, Alyson needs enough beads to make one more complete bracelet. Since each bracelet requires 5 beads, and she has 1 bead left after making 9 bracelets, she would need 4 more beads to make the 10th bracelet. Hence, Alyson would need to acquire 4 more beads to use all her beads without any remaining.

Cindy's shortcut will not work because;

She made a mistake by not multiplying the 2 tens by 3 .

Now, for 24; 2 is the tens digit and 4 is the units digit.

This means according to partial products, we can rewrite 24 as; (2 × 10) + (4 × 1)

Now, to multiply 3 by (2 × 10) + (4 × 1) gives the expression;

3[(2  × 10) + (4 × 1)]

3(2  × 10) + 3(4 × 1)

This corresponds with the solution i got which is 3(4 × 1) = 12.

Now, the second part of the solution is; 3(2  × 10) = 60

But she just used 2 tens which is (2 × 10) = 20.

This means she failed to multiply 2 tens by 3 and that was her mistake.

Answer:

Elias is not correct. The new rectangle will be an enlargement because the scale factor is greater than 1. To be a reduction, the scale factor must be between 0 and 1.

Scale factor less than 1 gives the expanded form of the figure so Elias is wrong.

You must specify the extent of the shape's enlargement when describing one.

The scale factor is the ratio of two dimensions such that one figure is large and another is small.

The scale factor is done due to the unpractical measurement of any figure.

If the dimension of any figure is 2 units by using scale factor 2/1 it will become 2 × scale factor ⇒ 2 × 2/1 = 4

Similarly,

Scale factor 8/3 creates all dimensions by a factor of 8/3 = 2.67 so all dimensions will be going to expand.

Hence "Scale factor less than 1 gives the expanded form of the figure so Elias is wrong".

Alyssa can design her garage with dimensions that are factors of 240 square feet. Possible dimensions range from 1 ft x 240 ft to 15 ft x 16 ft, with more practical and reasonable options being dimensions that are narrower but still close to a square, such as 12 ft x 20 ft or 15 ft x 16 ft.

The question regarding Alyssa's garage design involves finding all the pairs of whole numbers that multiply to give an area of 240 square feet for a rectangular floor. To determine this, we must find the factors of 240 that can serve as potential lengths and widths of the garage.

Factors of 240 that represent possible lengths and widths (where the first number in each pair is the length and the second is the width) are:

However, choosing the dimensions that are reasonable for a garage floor requires considering practicality. Very long and narrow rectangles, such as 1 ft x 240 ft or 2 ft x 120 ft, are not practical for a garage. Usually, dimensions that are closer to square but still rectangular, like 12 ft x 20 ft or 15 ft x 16 ft, are more suitable and reasonable for a garage.

Answer:

answer is C

Step-by-step explanation:

Final answer:

The question deals with an inequality representing that the product of an unknown number and 4 is at least -12, resulting in a solution where the number must be greater than or equal to -3.

Explanation:

The question 'The product of a number and 4 is at least -12' can be translated into the inequality 4x ≥ -12, where x represents the number. To solve this, divide both sides of the inequality by 4, which follows the multiplication rules for the sign. This gives us x ≥ -3. So, the number must be greater than or equal to -3.

This is consistent with the fact that when two negative numbers multiply, the answer is positive, and when a positive and a negative number multiply, the answer is negative.

Answer:

Step-by-step explanation:

We can express the charge made by the companies as equations.

The charge made by the Company A starts at 35 cents, and cost 3 additional cents per minute. We can write this as:

[tex]charge_A(t)= 35 \ c + 3 \ \frac{c}{min} * t[/tex]

where t is the length of the call in minutes. For the company B the charge starts at 45 cents, and cost 2 additional cents per minute. This is:

[tex]charge_B(t)= 45 \ c + 2 \ \frac{c}{min} * t[/tex].

Now. At what length t' the cost of the phone call is the same? We can write the condition as:

[tex]charge_A(t')= charge_B(t')[/tex]

this means:

[tex]35 \ c + 3 \ \frac{c}{min} * t'= 45 \ c + 2 \ \frac{c}{min} * t'[/tex]

doing a little work...

[tex]35 \ c + 3 \ \frac{c}{min} * t' - 35 \ c = 45 \ c + 2 \ \frac{c}{min} * t' - 35 \ c[/tex]

[tex]3 \ \frac{c}{min} * t'= 10 \ c + 2 \ \frac{c}{min} * t'[/tex]

[tex]3 \ \frac{c}{min} * t' - 2 \ \frac{c}{min} * t'= 10 \ c[/tex]

[tex] 1 \ \frac{c}{min} * t'= 10 \ c[/tex]

[tex] \frac{1 \ \frac{c}{min} * t'}{1 \ \frac{c}{min}}= \frac{10 \ c}{1 \ \frac{c}{min}}[/tex]

[tex] t'= 10 min [/tex]

And this is the length of time we are looking for.
