Victoria is at an elevation of 150 feet. She hikes down to an elevation of 120 feet in 40 minutes. Then she hikes down to an elevation of 100 feet in 30 minutes.
Answers
Answer:
Answer: First portion is greater than second portion.
Step-by-step explanation:
Time taken to hiked down a trail = 10 minutes
Change in elevation = (-) 170 feet
Speed is given by
\begin{gathered}Speed=\frac{Distance}{Time}\\\\Speed=\frac{170}{10}\\\\Speed=17\text{ feet per minute}\end{gathered}
Speed=
Time
Distance
Speed=
10
170
Speed=17 feet per minute
Similarly,
Time taken to hiked down a trail = 20 minutes
Change in elevation = (-)220 feet
Speed is given by
Speed=\frac{Distance}{Time}Speed=
Time
Distance
\begin{gathered}Speed=\frac{220}{20}\\\\Speed=11\text{ feet per minutes}\end{gathered}
Speed=
20
220
Speed=11 feet per minutes
So, we can see that first portion of the hike where he hiked down a trail at a steady rate for 10 minutes and her change in elevation was (-) 170 feet, was her rate of change in elevation greater.
As 17 feet per minutes is greater than 11 feet per minutes.
Tammy cuts four identical circles from a square piece of black poster board as shown. What is the area of the leftover poster board?
a) 6.240 square feet
b) 5.375 square feet
c) 18.760 square feet
d) 19.625 square feet
Answers
Answer:
B) 5.375
Step-by-step explanation:
The circles are half the square so their diameter will be half the length of the square
d=5/2=2.5
the formula is
area of shaded portion-area out unshaded portion
area of a square= l×l
5×5=25
area of a circle=πr^2
but since there are 4 circles it becomes 4πr^2
r=d/2=2.5/2=1.25
area of unshaded portion= 4×3.14×1.25×1.25
=19.625
area of leftover=25-19.625
= 5.375

Answers
Answer:
3 7/12
Step-by-step explanation:
First find the common denominator.
8,16,24
3,6,9,12,15,18,24
Once you find the common denominator. You have to fix the numerator.
7 2/8 would become 7 6/24
Whole numbers stay the same.
8 x 3 = 24
2 x 3 = 6
Now we repeat it on the other mixed number.
3 2/3 would become 3 16/24
Again whole numbers stay the same.
3 x 8 = 24
2 x 8 = 16
Once you convert the fractions to having the same denominator you subtract like normal.
7 6/24 - 3 16/24 = 3 14/24
3 14/24 can be simplified to 3 7/12
Answer:
[tex]\boxed{3 \dfrac{7}{12}}[/tex]
Step-by-step explanation:
The first step in simplifying the expression is to convert both the fractions into improper fractions [a/b (a > b)].
⇒ [tex]7\dfrac{2}{8} - 3\dfrac{2}{3}[/tex]
⇒ [tex]\dfrac{7 \times 8 + 2}{8} - \dfrac{3 \times 3 + 2}{3}[/tex]
⇒ [tex]\dfrac{56 + 2}{8} - \dfrac{9 + 2}{3}[/tex]
⇒ [tex]\dfrac{58}{8} - \dfrac{11}{3}[/tex]
The next step in simplifying the expression is to make the denominators of both fractions equivalent.
⇒ [tex]\dfrac{58}{8} - \dfrac{11}{3}[/tex]
⇒ [tex]\dfrac{58 \times 3}{8 \times 3} - \dfrac{11 \times 8}{3 \times 8}[/tex]
⇒ [tex]\dfrac{174}{24} - \dfrac{88}{24}[/tex]
The third step in simplifying the expression is to subtract the fractions.
⇒ [tex]\dfrac{174}{24} - \dfrac{88}{24}[/tex]
⇒ [tex]\dfrac{86}{24}[/tex]
The fourth step in simplifying the expression is to simplify the difference of the two fractions.
⇒ [tex]\dfrac{86}{24}[/tex]
⇒ [tex]\dfrac{86 \div 2}{24 \div 2}[/tex]
⇒ [tex]{\dfrac{43}{12}}[/tex]
The fifth step in simplifying the expression is to convert the improper fraction into mixed fraction.
⇒ [tex]{\dfrac{43}{12}}[/tex]
⇒ [tex]{\dfrac{36}{12}} + \dfrac{7}{12}[/tex]
⇒ [tex]3 + \dfrac{7}{12}[/tex]
⇒ [tex]\boxed{3 \dfrac{7}{12}}[/tex]

Answers
Answer:
The number would be 90
Step-by-step explanation:
140 + 10 - 90 = 60
90 - 30 = 60
60 = 60
Answer: 90
Step-by-step explanation:
Let's use x as a placeholder to the number we are trying to find
[tex]140+10-x=x-30[/tex]
Now we need to isolate x
Step 1) Simplify both sides
[tex]140+10-x=x-30\\150-x=x-30[/tex]
Step 2) Add 30 to both sides
[tex]150-x+30=x-30+30\\180-x=x[/tex]
Step 3) Add x to both sides
[tex]180-x+x=x+x\\180=2x[/tex]
Step 4) Divide both sides by 2
[tex]\frac{180}{2}=\frac{2x}{2} \\90=x[/tex]
Step 5) Sub our value into the original equation and solve
[tex]140+10-x=x-30\\140+10-90=90-30\\150-90=60\\60=60[/tex]

Answers
Answer:
x = 7
Step-by-step explanation:
Just write what you see in terms of a formula.
2x - 9 = 5
Solve for x
add both sides by 9
2x = 5 + 9
2x = 14
divide both sides by 2
x = 14/2
x = 7
Answer:
x = 7
Step-by-step explanation:
9 subtracted from 2x gives the result 5. Find the value of x.
Translate:
2x - 9 = 5
Simplify:
2x - 9 = 5 <== add 9 to both sides
+ 9 + 9
2x = 14 <== divide both sides by 2 to isolate the variable

As there are gaps between the classes, the lower boundaries will be 0.5 less and the upper boundaries will be 0.5 more.
Class width = 10.5 - 5.5 = 5

The circumference of a circle is 94.2 kilometers. What is the circle's diameter?
Answers
Answer:
The diameter would be 29.98 kilometers.
Step-by-step explanation:
We know that our circumference is pi * diameter, so we just have to divide 94.2 by pi to solve.
Answer:
30 km
Step-by-step explanation:
We can use the below formula to find the diameter of a circle.
C = π × d
Here,
C ⇒ circumference ⇒ 94.2 km
d ⇒ diameter
To find the diameter make d as the subject in the above formula.
d = C / π
d = 94.2 / 3.14
d = 30 km

Now that we know that it is 4 we can divide the eqiasion by 4 and then you get

According to a weather report on the probability that it will rain tomorrow, the probability that it will not rain tomorrow is 89%.
What is Probability?
Probability is simply the likelihood that something or an event is to happen.
Now, the probability that an event will not occur is one minus the probability that the event will occur.
Given the data in the question;
Probability that it will rain tomorrow p = 11%Probability that it will not rain tomorrow p⁰ = ?The probability that it will not rain tomorrow is one minus probability that it will rain tomorrow.
p⁰ = 1 - p
p⁰ = 1 - 11%
p⁰ = 1 - ( 11 / 100 )
p⁰ = 1 - 0.11
p⁰ = 0.89
p⁰ = 89%
Therefore, According to a weather report on the probability that it will rain tomorrow, the probability that it will not rain tomorrow is 89%.
