A car drove 55 miles per hour for 8.2 hours and 75 miles per hour for 3.6 hours. How far did the car drive?
Answers
Answer:
Step-by-step explanation:
So at 38mph you are roughly traveling .6333 miles a minute. So 13 miles would take you roughly 8.2 minutes. How does one figure out this?
We know that there are 60minutes in an hour. We know you’re driving 38miles per hour. Dividing 38 by 60 gives you the miles per minute. Multiple that by how many miles you’re driving to get an estimate of the minutes it takes to drive those miles.
A rectangular garden is 16 feet wide. Its length is 8 feet more than twice the width. What is the area of the garden?
Answers
Answer:
640 ft²
Step-by-step explanation:
Hi there!
We're given:
Width = 16
Length = 2 x Width + 8
Solve for the length:
l = 2(16)+8
l=32+8
l=40
Therefore, the length of the garden is 40 ft.
To find the area, multiply the length and width:
A = lw
A = (16)(40)
A = 640 ft²

What is the probability that the chosen child is a girl?
Give your answer as a fraction.
b)
What is the probability that the chosen child is a left-handed girl?
Give your answer as a fraction.
Answers
Answer:
A. 2/5
B. 1/10
Step-by-step explanation:
First off we need to calculate the probability that the chosen child is a girl So to calculate this probability, we have to know the num. of girls which is seen in the table. There are a total of 8 girls.
Therefore the probability of a girl being chosen is equivalent to the number of girls/exact number of children = 8/20 = 2/5 simplified.
Now to find the probability that the chosen girl is left-handed.
The amount of left-handed girls there is only 2. therefore the probability of selecting a left-handed girl will be 2/20 = 1/10 simplified.

A triangle has an angle that measures 55°. The other two angles are in a ratio of 11:14. What are the measures of those two angles?
Answers
9514 1404 393
Answer:
55° : 70°
Step-by-step explanation:
The sum of the two other angles is ...
180° -55° = 125°
The sum of the ratio units is 11+14 = 25. Each ratio unit stands for 125°/25 = 5°. Then the other two angles are ...
11×5° = 55°
14×5° = 70°
Answer:
55° and 70°
Step-by-step explanation:
A triangle has an angle that measures 55°. The other two angles are in a ratio of 11:14. What are the measures of those two angles?
the sum of the internal angles of a triangle is 180 °, we take 55 ° of the known angle and we have the sum of the other two, 125 °, the ratio is 11:14, one is 11 units and one is 14 units, we add them and we divide 125 ° by (11 + 14) = 25 and we have a unit, 125: 25 = 5. now we multiply the unit first by 11 and then by 14 and find the measure of the angles.
11 * 5 = 55°
14 * 5 = 70°
--------------------
check
55 + 55 + 70 = 180°
the sum of the interior angles of a triangle is 180,
so
the answer is good

The surface area of the rectangular prism below is 736 square units
Surface area of rectangular prismThe formula for calculating the surface area of the rectangular prism is expressed as:
A = 2(lw + wh + lh)
Given the following parameters
l = 8
w = 19
h = 8
Substitute
SA = 2(8(19) + 8(19) + 8(8))
SA = 2(152 + 152 +64)
SA = 2(304+ 64)
SA = 2(368)
SA = 736 square units

f() = -5 when f(t) = -3t + 4 is equal to 19. The value of t is -5
The given function is f(t) = -3t + 4. To find the value of f() when it is equal to 19, we substitute 19 in place of f() in the equation.
f() = -3() + 4
Since the value of f() is not provided, we can solve for it by setting the equation equal to 19:
-3() + 4 = 19
To solve for f(), we isolate the variable on one side of the equation. First, we subtract 4 from both sides:
-3() = 19 - 4
-3() = 15
Then, we divide both sides of the equation by -3 to solve for :
/ -3 = 15 / -3
= -5
It's important to note that the notation f() represents the value of the function at a specific point, usually denoted by a specific value in the parentheses. In this case, we were given f() = 19, and our task was to find the corresponding value of . By solving the equation, we determined that = -5 in this scenario.
Therefore, f() = -5 when f(t) = -3t + 4 is equal to 19.
