Tamia is getting balloons for her father's birthday party. She wants each balloon string to be 6 feet long. At the party store, string is sold by the yard. If Tamia wants to get 59 balloons, how many yards of string will she need?

Answers

Answer:

118 yards

Step-by-step explanation:

Tamia is getting balloons for her father's birthday party

She wants each balloon to be 6 feet long

Tamia wants to get 59 balloons

Therefore the yards of string needed can be calculated as follows

= 59×6

= 354 feet to yards

= 118 yards

Hence the number of yards needed is 118 yards

5. A student wants to know how tall the flagpole at her school is, her eye level is 5.5 feet above
the ground and she stands 36 feet from the base of the flagpole. If the angle of elevation is
25°, what is the height of the flagpole?

Answers

Answer:

22.3 ft

Step-by-step explanation:

Here we can make a triangle rectangle with the following vertex:

The student's eye level.

The top of the flagpole

The intersection between a horizontal line that passes through her eye level and a point in the flagpole.

The catheti of this triangle rectangle will be:

The distance between her and the flagpole (36ft)

The height of the flagpole minus the height of her eye level = H

We want to find the value of H.

We also know that the angle of elevation from her point of view is 25°.

(for this angle, the adjacent cathetus is the distance between her and the flagpole)

Now we can remember the relation:

Tan(a) = opposite cathetus/adjacent cathetus.

Then:

Tan(25°) = H/36ft

Solving for H we get:

Tan(25°)*36ft = H = 16.8 ft

And this is the height of the flag pole minus the height of her eye level, then the actual height of the flagpole is:

H + 5.5ft = 16.8 ft + 5.5ft = 22.3 ft

Step-by-step explanation:

The side ratios of a 30°-60°-90° triangle are ...

  1 : √3 : 2

In your triangle, they are ...

  x : 4 : y

In order to get these values, we need to multiply the reduced ratio by 4/√3 = (4√3)/3. Then we have ...

  x : 4 : y = (4√3)/3 : 4 : (8√3)/3

and we can see that ...

x = (4√3)/3y = (8√3)/3

Mel begins playing video games at the time on the left clock. If she stops playing video games at the time on the right clock, how many minutes did Mel spend playing video games?

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the required clocks are not given.

To answer this question, I will give an illustration of how to calculate the difference between times.

Note that: I assume you can read the time on a clock

Assume that:

[tex]Left\ clock = 2:15pm[/tex]

[tex]Right\ clock = 3:05pm[/tex]

The difference is calculated as:

[tex]Difference = Right\ clock - Left\ clock[/tex]

[tex]Difference = 3:05pm - 2:15pm[/tex]

From 2:15pm to 3:05pm is 50 minutes.

So:

[tex]Difference = 50\ minutes[/tex]

Another assumption:

[tex]Left\ clock = 2:15pm[/tex]

[tex]Right\ clock = 3:32pm[/tex]

The difference is calculated as:

[tex]Difference = Right\ clock - Left\ clock[/tex]

[tex]Difference = 3:32pm - 2:15pm[/tex]

For ease of calculation, we split the time to 2.

(1) From 2:15pm to 3:15pm

(2) From 3:15pm to 3:32pm

(1) From 2:15pm to 3:15pm: This is 1 hour

(2) From 3:15pm to 3:32pm: This is 17 minutes (i.e. 32 - 15)

So, the difference is:

[tex]Difference = 1hr + 17min[/tex]

[tex]Difference = 1\ hour\ 17minutes[/tex]

Step-by-step explanation:

The best way to do this is to put - 3x in for y in the second equation.

4x - 2(-3x) = - 20        Watch the signs. You have 2 minus signs.

4x - - 6x = -20            Change - - 6x to 6x

4x + 6x = - 20              Add

10x = - 20                   Divide by 10

x = -20/10

x = - 2

============================

Find y

how do i become smarter in math class and im in 8th grade 1 A blizzard struck the city of Phoenix, Arizona, on July 5, 2011. But it wasnt a frozen, white, swirling kind of blizzard. This storm was gritty, dark, and smothering. It was known as a black blizzard. Black blizzard is an American nickname for a dense cloud of dry particles that blankets a large area. It is commonly called a dust storm. The Phoenix blizzard towered 5,000 feet into the air, stretched 100 miles across, and plowed a 150-mile path before it finally calmed down. During the storm, visibility was nearly zero. 2 Its common to see a swipe of dust, dirt, or sand stirred up by a gust of wind. A black blizzard is the same experience multiplied many times over. Such storms are powered by high winds. Like water flowing in a river, fast air currents pick up and transport loose, dry soil. Lighter particles are swept up and carried for miles. Heavier particles are pushed forward by saltation. Saltation happens when blowing particles knock into stationary particles on the ground. The blowing particles set them in motion, too. Soon many particles bounce along by a series of skips and jumps. Saltated particles can work together to nudge pebbles and other objects. The nudging action is called creep. Saltation and creep come together to move massive amounts of material. In September 2009, a giant dust storm moved five million tons of red outback soil through Sydney, Australia! Watch Out . . . 3 Dust storms can severely affect whatever or whoever gets in their way. The grinding blast damages crops, livestock, buildings, and vehicles. Dust storms can have harmful effects on human health, too. They make breathing illnesses much worse. Dust storms stir up bacteria, molds, and fungi, which can cause valley fever, an infection that often follows dust storms in Phoenix. Virologists believe valley fever is caused by a soil fungus. . . .
