Answer:
Step-by-step explanation:
the perimeter of a triangle is 29cm. the three sides lengths (all measured in cm) of the triangle are 8, 12 and x. Write and solve an equation to find x.
Step-by-step explanation:
We have 8 + 12 + x = 29.
Solving, we get x + 20 = 29, x = 9.
Answer:
9 cm
Step-by-step explanation:
The perimeter of a polygon is the sum of the lengths of all the sides of the polygon.
If a polygon is a triangle, and its 3 sides have length a, b, and c, then the perimeter is the sum of a, b,, and c.
perimeter = a + b + c
Here, the perimeter = 29 cm
The lengths of the sides are a = 8 cm, b = 12 cm, c = x.
8 + 12 + x = 29
x + 20 = 29
x = 9
Answer: 9 cm
What is the slope of(-4,5) to (-12,8)
Answer:
-3/8
Step-by-step explanation:
I would use a table
x y
-4 5
-12 8
from -4 to -12 you subtract -8
from 5 to 8 you add 3
so y/x = 3/-8
The slope is - [tex]\frac{3}{8}[/tex]

Consider function h.
Answer:
-∞ < y < ∞
Step-by-step explanation:
Range corresponds to the values on the y-axis and Domain corresponds to values on the x-axis. Here if see the graph the range depends on values on y-axis and we can see that the the graph goes to -∞(-negative infinity) to +∞(positive infinity) so the answer is
-∞ < y < ∞
Answer:
The range is -∞< y < ∞, below is the explanation of how to get range.
Step-by-step explanation:
Given:
Graph of a function h(x).
To find:
The range of the function in inequality notation.
The range is all possible y-values of the function. Let's find all possible y values from the graph.
If we see the graph, it has a vertical asymptote at x=1 and a slant asymptote.
But it tool all y values from -infinity to infinity.
So, we can write range as -∞< y < ∞ because both sides of the function go and so on below the x-axis and go and so on above the x-axis.
The range is -∞< y < ∞ .

Twenty seconds after a plane in the air show- dives, it is 300 feet from where it begin. At what rate is the plane diving
Answer:
15 feets per second
Step-by-step explanation:
Given that:
Distance traveled by plane = 300 feets
Time taken by plane to travel such distance = 20 seconds
Rate at which the plane is diving is obtained thus :
Distance / time
= 300 feets / 20 seconds
= 15 feets / second
Hence, the plane is diving at a rate of 15 feets per second.
The number of fish in a lake decreased by 25% between last year and this year. Last year there were 60 fish in the lake. What is the population this year?
Answer:
This population, the population is 45 fish.
Step-by-step explanation:
This problem can be solved by a rule of three.
Last year there were 60 fish in the lake. That was 100, that is, decimal 1.
This year it decreased 25%. So there 100%-25% = 75%, that is decimal 0.75. So
60 fish - 1
x fish - 0.75
x= 60*0.75
x=45
This population, the population is 45 fish. Please make the brainliest.
60-25% of 60 =number of fish this year
60-25/100 x 60
60-15
45 fish are present in the lake

Mark takes out a $238,000 mortgage for 30 years. Instead of paying his monthly payment of $1,220.09, he decided to pay $1,420.09. This leads to Mark paying off the entire mortgage in 22 years and 5 months. Mark calculates the percent of the total loan he pays back in interest with and without the extra payments. What is the difference between Mark's calculated percentages?
Answer:
24.04%
Step-by-step explanation:
Given that:
Mortgage = $238,000
Number of years = 30
Monthly payment without extra payment= $1220.09
Monthly payment with extra payment = $1420.09
Total amount paid :
Number of months * monthly payment
12 months = 1year
30 years = (30 * 12) = 360 months (without extra payment)
22 years 5 months = (22 * 12) + 5 = 269 months (with extra payment)
Amount paid without extra payment :
$1220.09 * 360 = $439232.4
Percentage of total loan paid as interest :
((439232.4 - 238000) / 238000) * 100%
= 0.8455142 = 84.55%
Amount paid with extra payment :
$1420.09 * 269 = 382004.21
Percentage of total loan paid as interest :
((382004.21 - 238000) / 238000) * 100%
= 0.6050597 = 60.51%
Difference between percentages:
84.55% - 60.51% = 24.04%

Item 18 Two times the greater of two consecutive integers is 9 less than three times the lesser integer. What are the integers? Item 18 Two times the greater of two consecutive integers is 9 less than three times the lesser integer. What are the integers?
Answer:
11 and 12
Step-by-step explanation:
Let the consecutive integers be x and x+1
The lesser integer = x
The greater integer = x+1
Two times the greater of two consecutive integers is expressed as;
2(x+1) = 2x+2.
9 less than three times the lesser integer is expressed as;
3x - 9
Equate both expression
2x+2 = 3x - 9
2x-3x = -9-2
-x = -11.
x = 11
The greater integer = x+1 = 11+1 = 12
Hence the integers are 11 and 12
Answer:
11 and 12
