HEY CAN ANYONE PLS ANSWER DIS MATH PROBLEM!!!

Answer:

the answer for this problem should be half of 3.1 sense 2.5 is half of 5 so split 3.1 in have to get 1.55. hope this helps.

The number of miles that is equal to 2.5 km will be 1.55 miles.

A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.

Christof walks 2.5 kilometers to the library. He knows that 5 kilometers are approximately 3.1 miles.

Then we have

Let x be the number of miles that is equal to 2.5 km. Then we get

x/2.5 = 3.1/5

      x = 1.55 miles

Answer:

Red: 161 White: 77

Step-by-step explanation:

Given there are 238 marbles in a jar, and there are 42 more red marbles than white marbles, we need to divide the number of marbles by two, as there are, presumably, two colors.

238 / 2 = 119

After doing this, we subtract 42 from one of the two 119s, and we add 42 to the other.

119 - 42 = 77

119 + 42 = 161

The value with 42 added is the red marble count, and the value with 42 subtracted is the white marble count.

Answer:

time= half hour= 30 min  

words = 450

number of words in 30 min= 450

number of words in 1 min= 450/30

number of words in 7 min = 450/30 x 7

= 105 words

Answer:

Step-by-step explanation:

(-1 + 5)/(4 + 2) = 4/6= 2/3

y + 5 = 2/3(x + 2)

y + 5 = 2/3x + 4/3

y + 15/3 = 2/3x + 4/3

y = 2/3x - 11/3

Answer:

Yes, she does

Step-by-step explanation:

105min=1h 45min

14h 30min + 1h 45min= 16h 15min

16h 15min + 0h 20min=16h 35min

16h 45min - 16h 35min= 10min

So, the answer is yes, she does and she still has 10 minutes free.

Using proportions, it is found that Harri spent £76.91 on fuel last month.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations, especially multiplication and division with the rates.

For this problem, we have that Harri drove 850 miles with a rate of 45.6 miles per gallon hence the number of gallons that Harri used is given as follows:

850/45.6 = 18.64 gallons.

Each gallon is equivalent to 3.78541 liters, hence the number of liters that Harri used is given as follows:

18.64 x 3.78541 = 70.56 liters.

The cost per liter was of £1.09, hence the amount that Harri spent during the last month is given as follows:

70.56 x 1.09 = £76.91.

He will pat $94.60.

Step-by-step explanation:

Since you need to add 10% tax to your total, that is ten cents per dollar, and since you are adding it to the $86, you need to do 86 x 1.10, which is 94.60, and there you have it.

Answer: 250

Step-by-step explanation:

5/1250

5 divided by 1 is 0, because 5 cannot go into 1

bring the 2 down.

5 divided by 12 is 2, 2 times 5 is 10, 12 minus 10 is 2

bring the 5 down.

5 divided by 25 is 5, 5 times 5 is 25,

bring the zero down.

5 divided by 0 is 0, 5 cannot go into 0.

Answer:

El mayor número de panes que Mina puede hacer con la harina que tiene es 9 torrejas de pan.

Step-by-step explanation:

Una hogaza equivale a 12 torrejas de pan, si Mina tiene [tex]\frac{4}{5}[/tex] de la harina necesaria para preparar una hogaza. Entonces, el número total de torrejas es [tex]\frac{4}{5}[/tex] de 12 torrejas de pan. Es decir,

[tex]x = \frac{4}{5}\times 12[/tex]

[tex]x = 9.6[/tex]

Puesto que la cantidad de hogazas en un número entero, se trunca al entero más cercano. En consecuencia, el mayor número de panes que Mina puede hacer con la harina que tiene es 9 torrejas de pan.

Step-by-step explanation:

Step-by-step explanation:

1) c= 180°

22) b= 22 (vertical angle theorem)

a and c = 158 because you subtract b and 22° from 360 and you get 316 then divide by 2 to get a and c

Answer:

Step-by-step explanation:

Set up the following ratio which applies to all angle bisectors  and the side opposite.

8 / (x + 4) = 12 / (2x + 1)                Cross multiply

8 * (2x + 1) = 12 * (x + 4)

16x + 8 = 12x + 48                        Subtract 8 from both sides

16x + 8 -8 = 12x + 48-8

16x = 12x + 40                              Subtract 12x from both sides

16x - 12x = 40

4x = 40                                         Divide by 4

4x/4 = 40/4

x = 10

Answer:

b = 22

Step-by-step explanation:

Here b represents the length of the hypotenuse, and 11 is the length of the side opposite the 30 degree angle.  We want to find the value of b.  We use the sine function here because we have the angle measurement (b), the angle 30 degrees and the "opposite side" 11:

sin 30 degrees = (1/2) = 11/b, which, if inverted, is 2 = b/11, or b = 22

Lines of longitude run from North to South and are called Meridians

In a Geographical sense, meridians refer to great circles which intersect each other at the North and the South Poles.

Therefore,

Longitudes are also known as meridians.

The line drawn from north to south at 0 degrees is known as the prime meridian that divides Earth into two parts: the Eastern Hemisphere and the Western Hemisphere
