Answer:
x = 24 in
Step-by-step explanation:
The corresponding sides of similar triangle will be in same proportion.
[tex]\frac{x}{8}=\frac{15}{5}\\\\\frac{x}{8}=3\\\\x = 3*8\\x = 24[/tex]
Step-by-step explanation:

The distance a vehicle travels can be found by using the formula d = rt, where d is the total distance traveled, r is the rate of speed, and t is the amount of time spent traveling. Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour. To the nearest hour, how many hours does she spend driving?
Answer:
She spends 2 hours driving.
Step-by-step explanation:
The formula given is:
[tex]d = rt[/tex]
In which d is the distance traveled, r is the rate of speed, and t is the amount of time spent traveling.
Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour.
This means that [tex]d = 80, r = 50[/tex]
To the nearest hour, how many hours does she spend driving?
We have to find t. So
[tex]d = rt[/tex]
[tex]50t = 80[/tex]
[tex]t = \frac{80}{50}[/tex]
[tex]t = 1.6[/tex]
Rounding to the nearest hour
She spends 2 hours driving.

at total of 2 feet of snow falls over three days on the first day 1/6 of the snow falls on the second day 7/12 of the snow falls
PLZZ HELPP
Answer:
[tex]Day\ 3 = 1\frac{3}{12}[/tex]
Step-by-step explanation:
Given
[tex]Total = 2ft[/tex]
[tex]Day\ 1 = \frac{1}{6}[/tex]
[tex]Day\ 2 = \frac{7}{12}[/tex]
Required
Determine the amount of snow on day 3
This can be calculated using:
[tex]Day\ 1 + Day\ 2 + Day\ 3 = Total[/tex]
Substitute values for the known parameters
[tex]\frac{1}{6} + \frac{7}{12} + Day\ 3 = 2[/tex]
Collect Like Terms
[tex]Day\ 3 = 2 - \frac{1}{6} - \frac{7}{12}[/tex]
Take LCM
[tex]Day\ 3 = \frac{24 - 2 - 7}{12}[/tex]
[tex]Day\ 3 = \frac{15}{12}[/tex]
Express as mixed number
[tex]Day\ 3 = 1\frac{3}{12}[/tex]
find the tax sales on item divide the price of the item by 20 write an algebraic expression to find the sales tax on an item that cost three dollars find the sales tax on a television that cost $800
Answer:
Step-by-step explanation:
tax = 1/20 of price
1/20 of $3 = 1/20 × 3 = 3/20 = $0.15
1/20 of $800 = 1/20 × 800 = $40

Which expression represents the sum of n and 7 multiplied by 3? *
1. n + 7 x 3
2. (n + 7) x 3
3. (n + 7) ÷ 3
4. (n - 7) x 3
Answer:
Step-by-step explanation:
(n+7)×3
Answer:
1. n + 7×3Step-by-step explanation:
The sum of n and 7 multiplied by 3:
n + 7×3It is option 1
This is a tricky one but when reading carefully we see there is nothing that adds n to 7 before multiplying by 3, therefore it reads as n plus ( 7 multiplied by 3).
solve and graph 3t - 12 < -9
Answer:
x = anything lower than 1
Step-by-step explanation:
x < 1
The constraint of inequality 3t - 12 < -9 is t < 1 and has been plotted on a number line.
What is inequality?A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Given the inequality
3t - 12 < -9
Add 12 on both sides
3t - 12 + 12 < -9 + 12
3t < 3
Divide by 3 into both sides
t < 1
Hence "The constraint of inequality 3t - 12 < -9 is t < 1".

Can someone please urgently help me with this
Answer:
£ 268.2
Step-by-step explanation:
495(1/3)+124(0.5)+(495(2/3)-124)(0.2)=165+62+41.2
=268.2
Answer: £268.20
Step-by-step explanation:
1/3 of 495 is 165.
124 x .50 = 62.
165 + 124 = 289
495 - 289 = 206
206 x .20 = 41.20
165 + 62 + 41.20 = 268.20

Tyree wants to know if the value of -1 3/4, raised to the 12th power is a positive or negative number
9514 1404 393
Answer:
positive
Step-by-step explanation:
The exponent 12 tells you how many times (-1 3/4) is a factor in the product. The number 12 is even, so there will be an even number of minus signs in the product. That results in a positive product.

Help please due today!!!
Answer:
C
Step-by-step explanation:
Ivy says:
f(1) = -100
f(n) = -100 + 50( n - 1 )f(1) = -100 + 50( 1 - 1 )f(n) = -100 + 50(0 ) anything times 0 is 0!f(1) = -100You do that with the other numbers in the sequence. 2 = -50, 3 = 0 and so on
When you to n as 1, 2, and 3 they seem to all check out. So Ivy is right!
Andrey says:
f(1) = -100f(1)= -150 +50(1)f(1) = -150 + 50f(1) = -100That's a little suspicious don't you think that both answers are right..
Essentially they are both the same equation!
So let's simplify Ivy's equation!
f(n) = -100 + 50( n - 1 )
f(n) = -100 + 50n - 50
f(n)= -150 +50n
Which is basically Andrey's equation and they both seem to be right for the sequence! So both of them are right!
