This is not a very good thing to be doing, but I use Slader. On Slader, people answer the questions on textbooks. I guess it's kind of like Brainly, but the questions are already there. I used to use Slader for Big Ideas. Make sure to read the explanations so you get the topic though.
Jake plans to use a ramp to make it easier to move a piano out of the back of his truck. The back of the truck is 83 centimeters tall and the ramp is 158 centimeters long
Given :
Height of the ramp, h = 83 cm.
Length of ramp, L = 158 cm.
To Find :
Length of the base of the ramp.
Solution :
Let length of the base is l.
By Pythagoras theorem :
L² = h² + l²
[tex]l=\sqrt{L^2-h^2}\\\\l=\sqrt{158^2-83^2}\\\\l=134.44\ cm[/tex]
Therefore, length of the base is 134.44 cm.
Hence, this is the required solution.

Answer:
D.
Step-by-step explanation:
Both have a slope or "rate of change" of 1/2 because going from (0,5)-->(2,6) on the first one you go right 2 units and up 1 and slope is rise over run or y/x values in this case it would be 1/2 and on the bottom function you can see it goes from (0,-2)-->(4,0) and this goes right 4 units and up 2 units same principal applies you get 2/4 which is equal to 1/2 also it being negative or not doesn't change whether the two functions have the same rate of change.

Politician Alec and Candidate Simeon are running for governor. The latest surveys show that Politician Alec has 47% of the vote, while Candidate Simeon has 42% of the vote. The news report, however, states that this survey has a 6 % margin of error. What interval describes Politicians Alec's chances of winning the election?
Answer:
(41%, 53%)
Step-by-step explanation:
Given that:
Politician Alec's vote = 47%
Candidate Simeon = 42%
Margin of Error = 6%
Interval which describes Alec's chances of winning
Chances of Alec winning (p) = 47%
Margin of Error = 6%
Interval :
p ± margin of error
47% ± 6%
47% - 6% ; 47% + 6%
(41%, 53%)

What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Out of 200 people eating at a diner,
70% ordered sandwiches.
To find the number of sandwiches ordered:
Use percentage formula,
let n be the number of sandwiches ordered.
So, n = 70 x 200 / 100
n = 14000/100
n = 140
Therefore, 140 people ordered sandwiches.

The average emergency room cares for 300 patients each day. There are 20 nurses on duty at the emergency room each day, and they share the patient load equally.
Answer: 15
Step-by-step explanation:
You didn't say what you need to calculate but I guess that you want to calculate the number of patients each nurse will get.
Number of patients = 300
Number of nurses = 20
Number of patients to each nurse will be:
= Number of patients / Number of nurses
= 300/20
= 15
Each nurse gets 15 patient
Answer:
Step-by-step explanation:
There are 1$$ patients in the sample space.
There are 2$$ nurses on duty each day.
P(N)=3$$, is the probability that a patient will be assigned to a specific nurse.
Correct answers:
1$300$2$20$3$\frac{1}{20}$
The sample space is the set of all possible outcomes of an experiment. Here, there are 300 possible patients.
The event is a grouping of the outcomes in the sample space. Here, there are 20 possible nurses that a patient may have.
When the 300 patients are assigned equally to 20 nurses, that is equal to 15 patients per nurse. The probability of a patient being assigned to a specific nurse, N, is the comparison of being assigned to that nurse's patients versus all possible patients: P(N)=15/300=1/20.

Diego's family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when the remaining fuel is 1.5 gallons or less. Write an inequality to determine the number of days Diego's father can drive the car without the warning light coming on. 10 points 14− 0.6t > 1.5 14− 0.6t < 1.5 14+ 0.6t > 1.5 14+ 0.6t < 1.5
Answer:
[tex]14-0.6t>1.5[/tex]
Step-by-step explanation:
The amount of fuel the car holds is fixed i.e., 14 gallons
The amount of fuel consumed every day is 0.6 gallons
Warning light comes on when the fuel level is 1.5 gallons or less.
Let t be the number of days the car runs for
So the amount of fuel consumed in all the days must be less than 1.5.
The equation will be
[tex]14-0.6t>1.5\\\Rightarrow -0.6t>1.5-14\\\Rightarrow -0.6t>-12.5\\\Rightarrow 0.6t<12.5\\\Rightarrow t<\dfrac{12.5}{0.6}\\\Rightarrow t<20.83[/tex]
So, the number of days the car can be driven without the warning light coming on is less than 20.83 days.
Hence, the required inequality is [tex]14-0.6t>1.5[/tex].
Jeff sells popcorn for $3 per bag. To make a profit each day, he needs to sell at least $120 worth of popcorn. He has sold $36 worth of popcorn today. Which inequality can be used to find the number of bags of popcorn, p, Jeff still needs to sell today to make a profit?
Answer:
The inequality tha can be used to find how many more bags of popcorn Jeff still needs to sell today to make a profit is
x - 12 ≥ 40.
Step-by-step explanation:
Let us represent the number of bags of popcorn as p
Jeff sells popcorn for $3 per bag. To make a profit each day, he needs to sell at least $120 worth of popcorn.
We have the equation:
$3 × p ≥ $120
3p ≥ $120
p ≥ 120/3
p ≥ 40 bags
He must sell at least 40 bags to make a profit
He has sold $36 worth of popcorn today.
1 bag is $3
Hence, he has sold
$36/$3 = 12 bags of popcorn
Which inequality can be used to find Jeff still needs to sell today to make a profit?
This equality is given as:
x - 12 bags ≥ 40 bags
x - 12 ≥ 40
x ≥40 - 12
x ≥ 28 bags
She still need to sell 28 more bags of popcorn.
