Solve for the equation y/10 +2= −11.
Answer:
−11
Step-by-step explanation:
Subtract
2-2-2
from both sides of the equation 10+2=−11\frac{y}{10}+2=-11 10y+2=−1110+2−2=−11−2
Simplify:
Subtract the numbers 10=−13
Multiply all terms by the same value to eliminate fraction denominators:
10=−13\frac{y}{10}=-1310y=−1310⋅10=10(−13
Cancel multiplied terms that are in the denominator
Multiply the numbers:
=−130
Solution:
=−130

Question 1
You notice a hot air balloon descending. The elevation h (in feet) of the balloon is modeled by the function h(x)=-11x+330, where x is the time (in seconds) since you first noticed the hot air balloon.
Graph the function and specify its domain and range. Then interpret the slope and intercepts of the graph.
Answer:
Domain
[tex]x\in [0\,s,30\,s][/tex]
Range
[tex]h \in [0\,ft,330\,ft][/tex]
The h-Intercept represents the initial height of the balloon. The balloon has an initial height of 330 feet.
The x-Intercept represents the time when the balloon reaches the ground. The balloon takes 30 seconds to descend and reach the ground.
The slope represents the ratio of the change in the elevation of the balloon to the change in time. A slope of -11 means that balloon descends 11 feet per second.
Step-by-step explanation:
Both the time (domain), measured in seconds, and the height (range), measured in feet, are positive variables. The hot air balloon start at a height above and descends to the ground. Which means that domain and range of the function are, respectively:
Now we find the upper bound of the height of the hot air balloon. If we know that [tex]t = 0\,s[/tex], then the upper bound is:
[tex]h(0) = -11\cdot (0)+330[/tex]
[tex]h(0) = 330\,ft[/tex]
Range
[tex]h \in [0\,ft,330\,ft][/tex]
Now we find the upper bound of time. If we know that [tex]h = 0\,ft[/tex]. then the upper bound is:
[tex]-11\cdot x +330 = 0[/tex]
[tex]11\cdot x = 330[/tex]
[tex]x = 30\,s[/tex]
Domain
[tex]x\in [0\,s,30\,s][/tex]
The h-Intercept represents the initial height of the balloon. The balloon has an initial height of 330 feet.
The x-Intercept represents the time when the balloon reaches the ground. The balloon takes 30 seconds to descend and reach the ground.
The slope represents the ratio of the change in the elevation of the balloon to the change in time. A slope of -11 means that balloon descends 11 feet per second.

Identify the two missing sides of the 45-45-90 triangle
The area of the rectangular sheet is 500cm square. If the length of the sheet is 25cm, what is its width? Also find the perimeter of the rectangular sheet.
Answer:
20cm Perimeter: 90
Step-by-step explanation:
Hope this helps!(^-^)
Step-by-step explanation:
area of rectangular sheet is 500 CM square
length =25cm
area =l×b
500cm2=25cm×b
500cm2÷25cm=b
20cm=b
b=20cm
again,
perimeter =2(l+b)
perimeter =2(25cm+20)
perimeter =2×45
perimeter =90cm

Answer:
20Step-by-step explanation:
The equation of shifted function y = ax² is y = a(x-h)²+k, where h tells us how many units we move left (h<0) or right (h>0) and k tells how many units up (k>0) or down (k<0)
y = x² - 20 = 1(x - 0)² + (-20) ⇒ k = -20<0
So it's shifted 20 units down.
Vanessa owed her friend $24. She paid back $8. How much more does Vanessa need to pay before her account is at zero? –$16 –$8 $8 $16
Answer:
The answer is $16
Step-by-step explanation:
Venessa owed her friend $24. She paid back $8.
Account status = 8 - 24 = -$16
The amount remaining to pay to make account zero 24 - 8 = $16.
Answer:
The answer is D.) 16
Step-by-step explanation:
To solve this problem you are gonna do subtraction. What you are going to subtract is 24 - 8, because Vanessa took $24.00 from her friend and they want to you figure out how much she needs to pay back and in math when you are trying to figure out problems like this then you would use subtraction.
