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?
Answers
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
What is the slope of a line perpendicular to the line whose equation is
x+ 2y = –16. Fully reduce your answer.
Answers
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

A quarterback is sacked for a loss of 4 yards. On the next play, his team loses 10 yards. Then the team gains 12 yards on the third play. Write an addition expression to represent the situation. Then find the sum and explain its meaning.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the question:
Play 1: Quarterback was sacked for a loss of 4 yards
Play 2 : Another loss of 10 yards
Play 3: a gain of 12 yards
Write an addition expression to represent the situation. Then find the sum and explain its meaning.
A loss of 4 yards = - 4
Loss of 10 yards = - 10
Gain of 12 yards = + 12
Addition expression for the scenario :
(-4) + (-10) + 12
Result :
-4 + (-10) + 12
= - 4 - 10 + 12
= - 14 + 12
= - 2
Hence, after two consecutive losses of 4 and 10 yards, the team wins 12 yards on the third play and the aggregate yards lost is reduced to 2 yards.

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
Answers
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.

What is the scale if: 50 km in the actual distance correspond to 4 cm on the map?
Answers
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.

Need help please
Answers
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

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?
Answers
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.
These are Literal Equations. Solve for g: aeg=10.
Answers
Answer:
g = 10/(ae)
Step-by-step explanation:
When variables are shown like that, in reality they are multiplied:
aeg = 10 is the same as a * e * g = 10
Isolate the variable, g. Note the equal sign, what you do to one side, you do to the other. Simply divide variables a & e from both sides:
(aeg)/ae = (10)/ae
g = 10/ae
g = 10/(ae) is your answer.
