A function is a mapping that maps each element of its domain (student's name) to exactly one element of its co-domain (favorite ...). Assuming student names are unique and the notion of "favorite" is exclusive (can't have two or more "favorites" of the same type), then both A and B describe mappings that are functions.

Answer:

c. Both A and B

At the zoo the polar bears are fed 7/9 bucket of fish a day. The penguins are fed 4/7 that amount. What fraction are the penguins fed?

Answers

Answer: They are fed 4/9 of what the polar bears are fed.


Step-by-step explanation:

7/9*4/7=

1/9*4/1=4/9

The 7's get cancelled out.

                                       


Final answer:

The penguins at the zoo are fed 4/9 bucket of fish a day. This fraction has been calculated by multiplying the amount of food the polar bears get (7/9 bucket) by 4/7 as specified in the problem.

Explanation:

To find out how much the penguins are fed, we first understand the given units involving the polar bears and penguins. The polar bears are fed 7/9 bucket of fish a day, and the penguins are fed 4/7 that amount. Therefore, to calculate the amount the penguins are fed, we multiply the amount the polar bears are fed by 4/7.

We get this by performing the calculation (7/9) * (4/7). The sevens cancel out, leaving us 4/9, which is the fraction of the bucket of fish that the penguins are fed each day.

There are 17 students participating in a spelling bee. how many ways can the students who go first and second be chosen?

Answers

To determine the number of ways to choose two students to go first and second in a group of 17 students, we use permutations, resulting in a total of 17 * 16 = 272 ways.

The question inquires about the number of ways two students can be chosen from a group of 17 to go first and second in a spelling bee, which can be solved using combinatorics.

To choose the first student, we have 17 options. After choosing the first student, we have 16 remaining students to choose from for the second student. Therefore, the total number of ways to choose students for these two positions is the product of these two numbers. This scenario calls for a permutation calculation since the order in which we select the students matters.

The formula is n!/(n-r)!, where n is the total number of items to pick from, and r is the number we are picking. For our case, n = 17 and r = 2.

Total number of ways (permutations) = 17 * 16 = 272 ways.

Thanks!

Answers

Answer:

41

Step-by-step explanation:

If you work through a series of obscure calculations involving area and the radius of the incircle, they boil down to a simple fact:

... For MN║BC, perimeter ΔAMN = perimeter ΔABC - BC = AB+AC

.. = 17+24 = 41

_____

Wow! Thank you for an interesting question with a not-so-obvious answer.

_____

A little more detail

The point I that you have defined is the incenter—the center of an inscribed circle in the triangle. Its radius is the distance from I to any side, such as BC, for example.

If we use "Δ" to represent the area of the triangle and "s" to represent the semi-perimeter, (AB+BC+AC)/2, then the incircle has radius Δ/s. The area Δ can be computed from Heron's formula by ...

... Δ = √(s(s-a)(s-b)(s-c)) . . . . where a, b, c are the side lengths

For this triangle, the area is Δ = √38480 ≈ 196.1632 units². That turns out to be irrelevant.

The altitude to BC will be 2Δ/(BC), so the altitude of ΔAMN = (2Δ/(BC) -Δ/s). Dividing this by the altitude to BC gives the ratio of the perimeter of ΔAMN to the perimeter of ΔABC, which is 2s.

Putting these ratios and perimeters together, we get ...

... perimeter ΔAMN = (2Δ/(BC) -Δ/s)/(2Δ/(BC)) × 2s

... = (2/(BC) -1/s) × BC × s = 2s -BC

... perimeter ΔAMN = AB +AC

The perimeter of triangle AMN is found using the angle bisector theorem to determine the lengths of AM and AN, and recognizing that MN = BC due to the parallelism. After calculating, the approximate perimeter of triangle AMN is found to be 54.86.

In triangle ABC, the angle bisectors BD and CE intersect at I. A line through I parallel to BC intersects AB at M and AC at N. Perimeter of triangle AMN is found by adding lengths AM, MN, and NA. Since IM is parallel to BC and bisectors divide the angles proportionally, we have:

AM/AB = AI/AD, where D is the intersection of angle bisector BD with BC.

AN/AC = AI/AD, using similar logic.

MN is parallel to BC, so MN = BC due to the properties of parallelograms.

Using AB = 17, AC = 24, and BC = 33, find AM and AN using the proportional segments:

AM = (AI/AD) * AB

AN = (AI/AD) * AC

The perimeter of triangle AMN is AM + MN + AN.

To solve for AI/AD, we use the angle bisector theorem which gives us AI/AD = AB/BC = 17/33. Substituting this into the equations for AM and AN we get:

AM = (17/33) * 17

AN = (17/33) * 24

Computing these we find:

AM = 8.77 (approximately)

AN = 13.09 (approximately)

Lastly, we add AM, AN, and BC to find the perimeter:

Perimeter = AM + AN + MN

Perimeter = 8.77 + 13.09 + 33 = 54.86 (approximately)

This is the approximate perimeter of triangle AMN.

Triangles △ABC and △DFG are similar. The lengths of the two corresponding sides are 1.4m , and 56 cm. What is the ratio of the perimeters of these triangles ?

Answers

Answer:

5/2

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of corresponding sides:

... (140 cm)/(56 cm) = 5/2

Answer:

5:2

Step-by-step explanation:

We have been given that triangles △ABC and △DFG are similar. The lengths of the two corresponding sides are 1.4 m and 56 cm.

Since both triangles are similar, therefore all corresponding sides will have same proportion.

Let us find proportion of corresponding sides of both triangles.

1 meter = 100 centimeter

1.4 meter = 1.4* 100 centimeters = 140 centimeters.

[tex]\frac{\text{Side of triangle ABC}}{\text{Side of triangle DFG}}=\frac{140}{56}[/tex]

[tex]\frac{\text{Side of triangle ABC}}{\text{Side of triangle DFG}}=\frac{5}{2}[/tex]

The ratio of sides of △ABC to sides of△DFG is 5:2.

Since perimeter of a triangle is sum of lengths of three sides of the triangle and all sides of both triangle have the ratio 5:2, therefore, their perimeters will be in same ratio, that is 5:2.

Rhombus ADEF is inscribed in △ABC such that the vertices D, E, and F lie on the sides AB , BC , and AC respectively. Find the side of the rhombus if AB=7 cm, BC=5 cm, and AC=8 cm.

Answers

Answer:

3 11/15 cm

Step-by-step explanation:

AE is the angle bisector of ∠A, so divides the sides of the triangle into a proportion:

... BE:CE = BA:CA = 7:8

Then ...

... BE:BC = 7 : (7+8) = 7:15

ΔDBE ~ ΔABC, so DE = 7/15 × AC

... DE = 7/15 × 8 cm = (56/15) cm

... DE = 3 11/15 cm

Final answer:

To find the side of the inscribed rhombus, we can use the Pythagorean theorem and the properties of inscribed rhombuses.

Explanation:

To find the side of the rhombus, we need to understand the properties of inscribed rhombuses. In an inscribed rhombus, the diagonals are perpendicular bisectors of each other.

Let's label the side of the rhombus as 's'.

Using the given information, we can see that AB and AC are the diagonals of the rhombus.

Since AB = 7 cm and AC = 8 cm, we know that the diagonals bisect each other and form right angles.

Therefore, we can use the Pythagorean theorem to find the side of the rhombus:
s^2 = (AB/2)^2 + (AC/2)^2
s^2 = (7/2)^2 + (8/2)^2
s^2 = (49/4) + (64/4)
s^2 = (113/4)
s = sqrt(113/4)

kevin has $26 wants to rent bicycle.The bicycle rents for $6.25per hour. How many hours can kevin ride without owing more money than he has.

Answers

Answer:

I got 4 hours and 16 minutes

Step-by-step explanation:

I divided the amount of money he has ($26) to the amount it takes to rent for one hour ($6.25). To make it more simple you could just say 4 hours worth of rent.

Answer:


Step-by-step explanation:

Since Kevin only has $26 and the bicycle rends for $6.25 per hours this means that:

6.25h ≤ 26

Where h represents hours $6.25 is the slope (rate) at which Kevin is being charged and $26 is the amount of money he has.

By solving for the inequality above we obtain:

[tex]6.25h\leq 26\\\\\fra{6.25h}{6.25}\leq \frac{26}{6.25}\\\\h\leq4.16[/tex]

This means that Kevin can ride the bike for less than or equal to 4.16 hours.  Now that means 4 hours and 16% of an hour, let's calculate what 16% of an hour is equal to.  Since we know that there are 60 minutes in an hour and 16% is 0.16 (since 16÷100=0.16) in decimals we obtain:

60×0.16=9.6 minutes

This means 9 minutes and 60% of a minute, so we will calculate how much is 60% of a minute:

60×.6=36 seconds

Therefore, Kevin can ride this bike for less than or equal to 4 hours 9 minutes and 36 seconds.

Figure RHOM is a rhombus. and are the diagonals of the rhombus, as well as angle bisectors of the vertex angles, and they create four isosceles triangles: HOM, MHR, RHO, and OMR. What is true about MSR? It must be acute. It must be a right angle. It must be equal to MRH. It must be equal to RMS.

Answers

Answer:

∠MSR is right angle


Step-by-step explanation:

It is given that RHOM is a Rhombus

Also ΔHOM, ΔMHR, ΔRHO and ΔOMR are isosceles triangles

Let us take ΔMSR and ΔRSH

∠MRS =∠HRS            ( since it is given that the diagonal RO bisects ∠R)

∠RMS =∠RHS     ( since Δ MRH is isosceles triangle )

RS = RS        ( common side )

By AAS congruency rule ΔMSR ≅ ΔHSR

so we have

∠MSR=∠RSH  ( corresponding parts of congruent triangles are congruent)

also we have

∠MSR +∠RSH =180°   ( supplementary angles)

∠MSR +∠MSR=180°          ( since ∠MSR=∠RSH)

2∠MSR= 180°

∠MSR =90°

Hence ∠MSR is right angle


Answer:

It must be a right angle.

Step-by-step explanation:

The figure attached shows the rhombus RHOM with RO and HM as diagonals and are the angle bisectors of the vertex angles.

Let S be the point where the diagonals RO and HM intersects each other.

ΔHOM, ΔMHR, ΔRHO, ΔOMR are four isosceles triangles in the given rhombus.

Since, Diagonals of a rhombus bisect each other at right angle.

Therefore, we have ∠MSR= 90°

That is, ∠MSR is a right angle.

Answer:

 -240  -240

x=185

Final answer:

The question is about simple subtraction in mathematics. Given that Kyle and Tyler together traveled 425 miles and Kyle traveled 240 miles, we use subtraction to find out that Tyler traveled 185 miles.

Explanation:

This is a classic problem of simple subtraction in mathematics. Given, Kyle and Tyler together traveled 425 miles. Now, if Kyle traveled 240 miles, Tyler must have covered the remaining distance. So, to find out how far Tyler traveled, subtract the distance that Kyle traveled from the total distance. This is represented by the equation (option B) x + 240 = 425, where x represents the distance that Tyler traveled. Solving this equation for x will give you the answer.

Setup the equation: x + 240 = 425

Subtract 240 from both sides: x = 425 - 240

This results in x = 185, meaning Tyler traveled 185 miles.

In the attached, we have renamed F to G so Brainly will let us talk about it more easily. We have also added altitude MX.

AG is also a midsegment of ΔKLM, so LM = 2×AG = 4. Then ...

... NX = AB - LM = 7 -4 = 3

and we have right ΔMXN with hypotenuse 6 and leg 3. This is recognizable as a 30°-60°-90° triangle, with the 60° angle at N.

The angle at M is supplementary to that at N (because LM ║ KN), so measures 120°

The trapezoid is isosceles, so angles K and L have the same measures as angles N and M.
