Once he passes his friends, The miles Josiah has left to run would be 10.95 miles.
What is addition?The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
Josiah is running a marathon which is 26 1/5 miles long.
At four 1/4 miles from the start, he meets his wife, who is cheering him on.
7 1/2 miles further down the marathon course.
26 1/5 = 131/ 5
7 1/2 = 15/2
The marathon run by Josiah
= 1/4 + 15/2
= 15.25
The miles Josiah has left to run
= 131/ 5 - 15.25
= 10.95

Deja draws a marble from the bag randomly without looking. She then draws another marble from the bag without replacing the first one. Which expression shows the probability of drawing red marbles in both the trials?
5 over 15 multiplied by 4 over 14
5 over 15 multiplied by 4 over 15
5 over 15 added to 4 over 14
5 over 15 added to 4 over 15
Answer:
[tex]\huge\boxed{\sf \frac{5}{15} + \frac{4}{14} }[/tex]
Step-by-step explanation:
Formula for probability: [tex]\boxed{\displaystyle Probability = \frac{number\ of\ possible\ outcomes}{total\ number\ of \ outcomes} }[/tex]Solution:Total number of marbles = 5 + 8 + 2 = 15
Number of red marbles = 5
Probability to draw a red marble at the first trial = 5/15
Number of marbles left = 15 - 1 = 14
Number of Red marbles left = 5 - 1 = 4
Probability to draw a red marble at the second trial = 4/14
Total probability:[tex]\displaystyle =Probability \ of \ drawing \ a \ red \ marble \ at \ the \ (second \ attempt +first \ attempt)\\\\= \frac{5}{15} + \frac{4}{14} \\\\\rule[225]{225}{2}[/tex]

From the top of a building, 30.15m high, the angle of depression of a point on the ground level 25.88'm from the base is B° find B
Answer:
49.36 degrees to the nearest hundredth.
Step-by-step explanation:
In the right angled triangle formed the adjacent side is 25.88 m and the opposite = 30.15 m.
So tan B = 30.15 / 25.88 = 1.16499
So m < B = 49.36 degrees.

Two similar polygons have a scale factor of three. The smaller polygon has an area of 42 cm² and perimeter of 50 cm. what is the area of the larger polygon? and what is the perimeter of the larger polygon?
Step-by-step explanation:
a scale factor applies to every line, that means also to every side of the polygon.
the area of a polygon is always created out of the product (multiplication) of 2 dimensions (or sides).
while a perimeter is a pure sum of sides.
so the perimeter grows by the same factor as the sides : scale factor 3.
the perimeter of the larger polygon is therefore :
50 × 3 = 150 cm
and the area of the larger polygon ?
remember, that the area is always the product of 2 sides (or the sum of products of 2 sides).
and so, the scale factor enters these multiplications twice, and it gets therefore squared : 3×3 = 9.
so, the area of the larger polygon is then
42 × 9 = 378 cm²

help with this??? i beg of you☹️☹️
Answer:
The answer is 3 cm.
Step-by-step explanation:
To find the width of the cereal box, we must first take the volume and divide it by the length and then divide that by the height.
For this equation, we would do the following:
3456 ÷ 36 = 96 cm²
Now that we have divided volume by length, let's divide by height next:
96 ÷ 32 = 3 cm
Now we know the height of the box. To check if this is correct, lets multiply the length, height, and width and see if we get the volume that we started with.
3 × 32 × 36 = 3456 cm³
Since we got the original volume that we started with, we know that the width is 3 cm which is your answer.

Answer:
a = 60, b = 19, c = 101, d = 79, e = 50
Step-by-step explanation:
Relations that are helpful here are ...
vertical angles are congruentan exterior angle is equal to the sum of the opposite interior anglesthe sum of angles forming a straight angle is 180°the sum of angles in a triangle is 180°__
Using these relations, we can find the unknown measures.
a° = 60° . . . . . these are vertical angles
51° +b° +110° = 180° ⇒ b° = 180° -161° = 19° . . . . straight angle
a° +b° +c° = 180°
c° = 180° -60° -19° = 101° . . . . sum of angles in a triangle
d° = 180° -101° = 79° . . . . . straight angle
e° = c° -51° = 50° . . . . . c° is exterior to the triangle

51. Jacob has a lemonade stand. On Monday, he sold x cups of
lemonade. On Tuesday, he sold 14 more cups than he sold on Monday.
Choose the expression below that shows how many cups of lemonade
Jacob sold on Tuesday.
a) 14 - x
b) x + 14
c)X - 14
d) x2 + 14
What expression would I use
Answer:
b) x + 14
Step-by-step explanation:
If I sold 14 more cups that what I sold Monday, then my answer should be (what I sold Monday) + (14).
Its like saying suppose I drank x gallons of water today. And next day, I drank 14 more gallons than yesterday. That means, I drank the initial amount of gallons (x) & 14 more gallons today (x+14)
Find the measure of each angle in the diagram.
The measure of each angle in the diagram are 4y° = -82°, (6y - 41)° = 164°, (3x + 2)° = 98°, 2(x + 17)°= 98
What are vertical angles?Each of the pairs of opposite angles made by two intersecting lines is called a vertical angle.
Two lines are intersecting each other at a point making two pairs of vertical angles.
The pair of vertical angles are equal in measure.
4y° = (6y + 41)° [Vertical angles]
4y - 6y = 41
2y = -41-----(1)
(3x + 2)° = 2(x + 17)° [Vertical angles]
(3x + 2)° = 2x + 34°
x = 32 ------(2)
Therefore, 4y° = -82°
(6y - 41)° = 164°
(3x + 2)° = 98°
2(x + 17)°= 98
