Use the tangent to find the length of side PR.Express your answer to the nearest tenth.
Answer:
PR = 4.9
Step-by-step explanation:
For given angle Q, RQ is the adjacent leg, and PR is the opposite leg.
We recall the meaning of the tangent ratio.
tan A = opp/adj
Here we have
tan Q = opp/adj
tan 51 deg = PR/4.0
PR = 4.0 * tan 51 deg = 4.9
Answer: PR = 4.9

Two triangles are cut from a rectangle to form a trapezoid. What is the ratio of the area of the trapezoid to the combined area of the triangles? A 18:54 C 54:18 B 18:72 D 72:18 12 in group of students is painting a background piece
The image showing the trapezoid is missing, so i have attached it.
Answer:
C 54:18
Step-by-step explanation:
Formula for area of trapezoid is;
A_trap = ½(sum of parallel sides) × height = ½(12 + (12 - (3 + 3))) × 6
A_trap = ½(12 + 6) × 6
A_trap = 54 in²
Combined area of triangle:
A_tria = 2 × ½ × 3 × 6 = 18 in²
Thus;
A_trap:A_tria = 54 in²:18 in² = 54:18
The image showing the trapezoid is missing, so i have attached it.
Answer:
C 54:18
Step-by-step explanation:
Formula for area of trapezoid is;
A_trap = ½(sum of parallel sides) × height = ½(12 + (12 - (3 + 3))) × 6
A_trap = ½(12 + 6) × 6
A_trap = 54 in²
Combined area of triangle:
A_tria = 2 × ½ × 3 × 6 = 18 in²
Thus;
A_trap:A_tria = 54 in²:18 in² = 54:18

what is x
Answer:
-6
Step-by-step explanation:
2x + 3(8) = 12

2x = 12 - 24
2x = -12
x = -12/2
x = -6

Answer:
Socko gained 3/5 kg from month 1 to month 2.
Step-by-step explanation:
Socko mass was 3/10 kg in month 1 and 9/10 kg in month 2.
The amount of mass he gained is k.
3/10 + k = 9/10
Subtract 3/10 from both sides.
k = 6/10
Reduce the fraction.
k = 3/5
Answer: Socko gained 3/5 kg from month 1 to month 2.

Does anybody know how to do this or at least part of it anything would really help!!
Answer:
So the given equation is h= -5t^2+40t
the first question asks when it will be 75 meters above the ground. So plug in 75 for h and find t
75= -5t^2+40t
start by dividing everything by 5
15= -x^2 + 8x
then you can add x squared to both sides and subtract 8x
x^2 - 8x + 15 =0
then you can plug it into the quadratic formula, which is a pain to type so I did it on paper.
x = 5 or 3
so it will be 75 meters above the ground at 3 seconds and 5 seconds
Rewriting the equation
ok so I accidentally already factored it when I divided everything by 5...
I believe the answer here is x^2 - 8x + 15 =0
The meaning of the x intercepts is when h=0 or the object is 0 meters above the ground (basically when it starts and when it ends)
the maximum height is greater than 75 because it gets to 75 meters 3 seconds after it is thrown, and continues going higher before it comes back to 75 two seconds later.
The object is airborne for 8 seconds because the second x intercept is at (8,0)

Answer:
14/3, or 4.6^bar
Step-by-step explanation:
first you'd just divide 7 by 9, resulting in [tex]\frac{7}{9}[/tex], or 0.7^bar.
Then you'd multiply either by 6, resulting in the answers above. Fractions are easier than infinite numbers, so if you're able to do that, I'd suggest you do so.

The distance from New York City to Riverhead is approximately 150 miles. On a map whose scale is 24mi= 2inch, what is the distance between the two locations in inches?
Answer:
12.5 inches
Step-by-step explanation:
Given
[tex]Distance = 150\ miles[/tex]
[tex]Scale:= 24\ miles : 2\ inches[/tex]
Required
Determine the measurement in inches
Represent the inches equivalent with d.
So, the scale can also be calculated as:
[tex]Scale:= 150\ miles: d[/tex]
Equate both scales
[tex]150\ miles: d = 24\ miles ; 2\ inches[/tex]
Convert to fraction
[tex]\frac{d}{150\ miles} = \frac{2\ inches}{24\ miles}[/tex]
[tex]\frac{d}{150} = \frac{2\ inches}{24}[/tex]
Multiply both sides by 150
[tex]150 * \frac{d}{150} = \frac{2\ inches}{24} * 150[/tex]
[tex]d = \frac{2\ inches}{24} * 150[/tex]
[tex]d = \frac{2\ inches * 150}{24}[/tex]
[tex]d = \frac{300\ inches}{24}[/tex]
[tex]d =12.5\ inches[/tex]

Answer: x = 10
The solutions to the equations as arranged are 2, -10, -0.4 and 10 respectively
Solving equationsGiven the following equations
x − 6 = -4
Add 6 to both sides
x - 6 + 6 = -4 + 6
x = -4 + 6
x = 2
For the equation x + 3 = -7
Subtract 3 from both sides
x + 3 -3 = -7 - 3
x = -10
For the equation 5x = -2
x = -2/5
x = -0.4
For the equation
0.5x = 5
x = 5/0.5
x =10
Hence the solutions to the equations as arranged are 2, -10, -0.4 and 10 respectively
