A triangle has a sides (x) feet, (x+3) feet, and (x+5) feet. The perimeter is 99.5 feet What is the measure for the largest side?
Answer:
35.5 feet
Step-by-step explanation:
x + x + 3 + x + 5 = 99.5
3x + 8 = 99.5
3x = 91.5
x = 30.5
Largest side = (x+5)
30.5 + 5 = 35.5 feet

Jacques is standing 1200 meters from a cliff he is planning to climb. The angle of elevation from the ground to the top of the cliff is 35º. To the nearest meter, how tall is the cliff?
Answer:
840 m
Step-by-step explanation:
Please refer to the attached photo.
In the attached photo, h is the height of the cliff.
The following data were obtained from the attached photo:
Opposite = h
Adjacent = 1200
θ = 35 °
The height, h of the cliff can be obtained by using the Tan ratio as follow:
Opposite = h
Adjacent = 1200
θ = 35 °
Tan θ = Opposite /Adjacent
Tan 35 = h/1200
Cross multiply
h = 1200 × Tan 35
h = 1200 × 0.7
h = 840 m
Therefore, the cliff is 840 m tall.
#3 The question says the sun of two consecutive integers is 345. What are the integers?
#5 The sum of two consecutive even integers is 446. What are the two.integers?
Need help please
Step-by-step explanation:
#3 let the two consecutive integers be a, a+1.
a+a+1=345
2a+1=345
2a=345-1
2a=344
a=344/2=172...
the integers are 172, 173
#5 let the consecutive even integers be a, a+2
a+a+2=446
2a=446-2
2a=444
a=444/2=222..so the even integers are 222, 224

What is the slope of a line perpendicular to the line whose equation is
x+ 2y = –16. Fully reduce your answer.
Answer:
slope = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
x + 2y = - 16 ( subtract x from both sides )
2y = - x - 16 ( divide all terms by 2 )
y = - [tex]\frac{1}{2}[/tex] x - 8 ← in slope- intercept form
with slope m = - [tex]\frac{1}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2
b. If some amount of water contains 1400 oxygen atoms, how many hydrogen atoms does it contain?
hydrogen atoms

c. If some amount of water contains 3380 oxygen atoms, how many hydrogen atoms does it contain?
hydrogen atoms
Preview
d. Write a formula that expresses the number of hydrogen atoms (y) in any time amount of water in terms of the number of oxygen atoms
that amount of water.
Answer:
B: 2800 hydrogen atoms
C: 6760 hydrogen atoms
D: y=amount of oxygen atoms*2
Step-by-step explanation:
B: We know the formula for water is H2O. SO that means that there is 2 hydrogen atoms and 1 oxygen atom. So there is 2 times the amount of hydrogen atoms so we can do 1400*2=2800, So there is 2800 hydrogen atoms in the water.
C: Same thing as B. 3380*2=6760
D: y=amount of oxygen atoms*2. Because there is one oxygen atom and two hydrogen atoms so 1*2=2.

What is the scale if: 50 km in the actual distance correspond to 4 cm on the map?
The scale is 1 cm: 12.5 km
To get this answer, you start off with the ratio 4 cm: 50 km which is given to us. It means that 4 cm corresponds to 50 km.
Divide both parts of the ratio by 4
4/4 = 1
50/4 = 12.5
The ratio 4 cm: 50 km simplifies to 1 cm: 12.5 km
1 cm on paper represents 12.5 km in real life.
The scale is 1cm on map represents 12.5 km in actual distance.
How to calculate the scale factor?Suppose the initial measurement of a figure was x units.
And let the figure is scaled and new measurement is of y units.
Since the scaling is done by multiplication of some constant, that constant is called scale factor. Let that constant be 's'.
Then we have:
[tex]s \times x = y\\s = \dfrac{y}{x}[/tex]
Thus, scale factor is the ratio of the new measurement to the old measurement.
The ratio 4 cm: 50 km which is given to us means that 4 cm corresponds to 50 km.
Divide both parts of the ratio by 4;
4/4 = 1
50/4 = 12.5
Thus, The ratio 4 cm: 50 km simplifies to 1 cm: 12.5 km
Therefore, 1 cm on paper represents 12.5 km in real life.

To find p(10) substitute n = 10 into the rule, that is
p(10) = - 10 - 1 = - 11
Steps to solve:
P(n) = -n - 1; p(10)

HELP 50 POINTS Solve the system of equations using either the linear combination method or the substitution method. SHOW ALL STEPS! I need help badly. 2x + 5y = 1 -3x + 4y = -13
Step-by-step explanation:
2x + 5y = 1 and -3x + 4y = -13
From equation 1, 2x = 1 - 5y, x = 0.5 - 2.5y.
Substitute into equation 2:
-3(0.5 - 2.5y) + 4y = -13
-1.5 + 7.5y + 4y = -13
11.5y = -11.5
y = -1.
We know that x = 0.5 - 2.5y = 0.5 - 2.5(-1) = 3
Hence x = 3, y = -1.
Simplify the following expression: 1.5 - 4 + 13

Have a NICE day
The larger number is 77 and the smaller number is 20.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, The sum of two numbers is 97.
Assuming the numbers to be a and b.
∴ a + b = 97...(i)
Also given, The larger number is three less than four times the smaller number,
Assuming the larger number to be a, therefore a = 4b - 3...(ii)
Substituting the value of a in eqn(i) we get,
4b - 3 + b = 97.
5b = 100.
b = 20, hence a = 77.
