Answers

Use csc (90) = 10/m.

So, m = 10/csc(90).

m = 8.93997

Answer:

m = 8

Step-by-step explanation:

Here's your solution

=> in traingle DHF and traingle EGF

we have angle DHF and EGF = 90°

and angle F is common , so both traingle are similar by AA similarity

=> 12/m = 15/10

=> m = 120/15

=> m = 8

Tatum walks her dog 2/3 mile every day after school. How many miles does she walk her dog in 5 days

Answers

The answer should be b!

The number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)

How to add two fractions?

Let we have to add two fractions as:

[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]

Then we will find Lowest Common Multiple (LCM) of [tex]b_1[/tex] and  [tex]b_2[/tex]. That will help to make the denominators same.

Once the denominators become same, the numerators can add up directly, giving us the final result of addition.

For this case, we're given that:

Each day, Tatum walks her dog 2/3 miles

For 5 days, the total distance her dog walked = 2/3 + 2/3 + 2/3 + 2/3 + 2/3

Since denominators are same, thus:

[tex]\dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} = \dfrac{2+2+2+2+2}{3} = \dfrac{10}{3}[/tex]

We could've easily done it as: 2/3 + 2/3 + 2/3 + 2/3 + 2/3 = 5 times 2/3 = [tex]5 \times \dfrac{2}{3} = \dfrac{5 \times 2}{3} = \dfrac{10}{3}[/tex]

Thus, the number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)

The students at Rudy's school voted between a bear and a lion as the new school mascot. 14 students voted for the bear and 86 students voted for the lion. What percentage of students voted for the bear?

Answers

Answer:

14%

Step-by-step explanation:

Given :

Bear voters = 14

Lion voters = 86

Percentage of students who voted bear :

(Bear voters / total number of Voters) * 100%

Total number of voters = (bear voters + lion voters) = (14 + 86) = 100

Percentage of students who voted bear :

(14 / 100) * 100%

0.14 * 100%

= 14%

During halftime of a football ​game, a slingshot launches​ T-shirts at the crowd. A​ T-shirt is launched from a height of 4 feet with an initial upward velocity of 80 feet per second. The​ T-shirt is caught 41 feet above the field. How long will it take the​ T-shirt to reach its maximum​ height? What is the maximum​ height? What is the range of the function that models the height of the​ T-shirt over​ time?

Answers

9514 1404 393

Answer:

  time to max height: 2.5 seconds

  max height: 104 ft

  range of function: [4, 104]

Step-by-step explanation:

The equation for ballistic motion is ...

  h(t) = -16t^2 +v0·t +h0 . . . . where v0 is the initial upward speed and h0 is the initial height

For the given parameters, the height function is ...

  h(t) = -16t^2 +80t +4

The time for maximum height is ...

  -b/(2a) = -80/(2(-16)) = 2.5 . . . seconds

The maximum height is ...

  h(2.5) = (-16·2.5 +80)(2.5) +4 = 104 . . . feet

The range of the function is from the minimum height (at launch) to the maximum height:

  4 ft ≤ h(t) ≤ 104 ft.

Please help me ... 6a + 2(c - b) when a = 2, b = 1, and c = 9 I know thë answer but I just need an explanation

Answers

Answer:

Step-by-step explanation:

Let the expression representing a situation is,

y = 6a + 2(c - b)

Where, a, b and c are the constants

If a = 2, b = 1 and c = 9

By substituting these values in the expression,

y = 6(2) + 2(9 - 1)

y = 12 + 16

y = 28

Therefore, for all given values of the constants value of y is 28.

2. -6 + 8d - 2c
3. -2c + 8d - 6
4. 6 - 3d + 2c

Answers

Answer:

2 and 3

Step-by-step explanation:

To simplify this expression, you will need to use the distributive property.

Multiply -2/5 by 15 = - 6, -2/5 by -20d = 8d, and -2/5 by 5c = -2c.

you can switch these around to get -6 + 8d - 2c and -2c + 8d - 6.
