Answer:

No

Step-by-step explanation:

Put both in your calculator. Do it in this order.

0.5484

=========

Now do the next one

14

=

1.357

19/14 > 17/31

First you use the formula (-b/2a) to find the axis of symmetry(or the x value) and then you plug that into the equation to find the y value.

a = 2

b= -16

16/2(2)=16/4=4

(4, x )  so we have the x-value and now we plug 4 into the original equation

y=2(4)^2-16(4)+8

y=2(16)-64+8

y=32-64+8

y=-24

So the vertex is at (4,-24)

The answer us A.

Line AC needs to be congruent to DF because for SAS (side angle side) we have a side (BA and DE) and an angle (A and D) so we need another side.

Answer:

A. [tex]\overline{AC}\cong \overline{DF}[/tex].

Step-by-step explanation:

We have been given image of two triangles ABC and DEF. We are asked to find the information that will show that both triangles are congruent by SAS.

We know that two triangles are congruent by Side-Angle-Side congruence, if two sides and included angle of a triangle is equal to two sides and included angle of the other triangle.

We can see that angle A is included angle of side AB and AC, while angle D is included angle of side DE and DF.

We have been given that angle A is congruent to angle D and side AB is congruent to side DE.

To be both triangles congruent by SAS congruence, side AC must be congruent to side DF, therefore, option A is the correct choice.

To simplify the given expression, distribute the fractions and combine like terms. The final simplified expression is 1/x + 24.

To simplify the given expression 1/2 (3/5x - 8) + 7/4 (2/5x + 4), we need to distribute the fractions across the terms. First, distribute 1/2 across 3/5x and -8, then distribute 7/4 across 2/5x and 4. This results in (3/10x - 4) + (14/20x + 28). Now, combine like terms by adding the coefficients of x. Thus, the simplified expression is (3/10x + 14/20x) + (-4 + 28).

To add the fractions (3/10x + 14/20x), we need to find a common denominator. The least common multiple of 10 and 20 is 20. Multiply the numerator and denominator of the first fraction by 2 and the numerator and denominator of the second fraction by 1 to obtain (6/20x + 14/20x). Now, add the fractions together to get (20/20x), which simplifies to 1/x.

Combine the constants (-4 + 28) to get 24. Therefore, the simplified expression is 1/x + 24.

Some number y has 7 subtracted off to get 15. We have y-7 = 15. To isolate y, we have to undo the "subtract 7" operation that happens to y. We have to add 7 to both sides.

y-7+7 = 15+7

Answer:

5 books

Step-by-step explanation:

Given that Toni carries upto 18 lbs in her backpack.

The maximum weight Toni can carry is 18 lbs.

Of these 18 lbs, already lunch of 1 lb and gym clothes of 2 lbs are included.

hence available for books is only the remaining 15 lbs.

Total weight in backpack= 18 lbs(Maximum)

Weight of lunch = 1 lb

Weight of her gym clothes = 2 lb

Hence maximum weight available for books = 18-(1+2) = 15 lbs

Weight of one book = 3 lbs.

No of books she can carry = 15/3 = 5 books

So, this is a rate per person * number of people.

So,

$916 per person * 72 people = 65,952

The city pays $916 per year for health insurance for;

each of 72 municipal employees

So;

1 municipal employee gets ⇒ $916

72 employees get ⇒ How much?

Cross multiplying gives:

72/1 × $916 = $65,952

The total cost the city pays per year is $65,952.

Answer:

7 days because 15 times 7 =105 and if you add 30 to that you get 135.

Step-by-step explanation:

The Webb family rented the car for 7 days.

To find the number of days the Webb family rented the car, we can set up an equation using the given information. Let's say the number of days the car was rented is x. The total cost would then be $30 (one-time fee) plus $15 (daily fee) multiplied by x. This can be represented as the equation: 30 + 15x = 135. To solve for x, we need to isolate it by subtracting 30 from both sides: 15x = 105. Then, divide both sides by 15: x = 7. Therefore, the Webb family rented the car for 7 days.

Answer:

=59+108+81+x=360

=248+x=360

=112

Considering the nearest-degree measurements, angle x falls between 58.5 and 108.5 degrees, determined by adjusting the upper and lower bounds based on the provided angles in the diagram.

Given that the angles in the diagram are measured to the nearest degree, we can determine the upper and lower bounds of angle x using the provided angles: 59 degrees, 108 degrees, and 81 degrees.

To find the upper bound of angle x, we select the largest angle, which is 108 degrees. The upper bound is obtained by adding 0.5 degrees to this angle (since measurements are to the nearest degree). Therefore, the upper bound of angle x is 108 + 0.5 = 108.5 degrees.

For the lower bound, we choose the smallest angle, which is 59 degrees. The lower bound is found by subtracting 0.5 degrees from this angle. Thus, the lower bound of angle x is 59 - 0.5 = 58.5 degrees.

In conclusion, the measure of angle x lies between the lower bound of 58.5 degrees and the upper bound of 108.5 degrees.

2=320

320/2=  160

Key:

*1=160

3*160=480

4*160=640

12*160= 1920

Working together for the same time, 3 combine harvesters can harvest 480 acres, 4 combine harvesters can harvest 640 acres, and 12 combine harvesters can harvest 1920 acres.

If two combine harvesters can harvest 320 acres in a certain amount of time, we need to find out how many acres can be harvested by 3, 4, and 12 combine harvesters working together for the same amount of time.

1. **Three combine harvesters**:

  Since 2 combine harvesters can harvest 320 acres, the harvesting capacity per harvester is:

  - 320 acres / 2 harvesters = 160 acres per harvester in the given time.

  Therefore, 3 combine harvesters can harvest:

  - 3 harvesters * 160 acres per harvester = 480 acres.

2. **Four combine harvesters**:

  Similarly, 4 combine harvesters can harvest:

  - 4 harvesters * 160 acres per harvester = 640 acres.

3. **Twelve combine harvesters**:

  Similarly, 12 combine harvesters can harvest:

  - 12 harvesters * 160 acres per harvester = 1920 acres.

In summary, working together for the same time, 3 combine harvesters can harvest 480 acres, 4 combine harvesters can harvest 640 acres, and 12 combine harvesters can harvest 1920 acres.

Answer: Each multiple choice question is worth 5 points.

Step-by-step explanation: You can find this answer by using the equation "14m + 24 = 16m + 14" and then solving for "m". To find what "m" is, you must first subtract 14m from both sides, leaving "24 = 2m + 14". Next, you subtract 14 from both sides, leaving "10 = 2m". Finally, you divide both sides by 2, which will give you "m = 5". Thus meaning each multiple choice question is worth 5 points.

To check this, simply fill in for "m" and solve each side. 14 * 5 + 24 = 94 and 16 * 5 + 14 = 94. 94 = 94, so "m = 5" is correct.

Hello There!

To divide fractions, all you have to do is leave the first fraction alone in the equation but multiply by the reciprocal in the second fraction. This means "Flipped Number" so you flip the numerator and denominator in the second fraction and multiply across then simplify if you need to.
