In isosceles triangle NTS, NT ≌ TS. If m∠N = 42° and NS = 30 cm, find the length of the altitude of △NTS. (Round answer to the nearest tenth.)
Answer:
13.5 cm
Step-by-step explanation:
The altitude of the base of the isosceles triangle bisects the vertex angle, <T, and also bisects the base, NS.
Therefore, NS is divide into two, 15 cm each.
This means we now have two right triangles from the isosceles triangle with the following:
Reference angle = 42°
Opposite = altitude = h
Adjacent = 15 cm
To find h, apply trigonometric function, TOA:
Tan 42 = Opp/Adj
Tan 42 = h/15
15 * Tan 42 = h
h = 13.5060607 ≈ 13.5 cm (nearest tenth)

Answer:
40ft
Step-by-step explanation:
Add up all four sides of your rectangle:
15ft + 15ft +5ft + 5ft = 40ft
You can find the other 5ft (the side that is missing) if you notice that the smaller sections are squares.
Decide whether or not it is a function.
Answer:
Step-by-step explanation:
Yes it's a function.
You may be looking at v which produces m
You may be looking at r which also produces m.
That's fine. Two different x values (the domain) can produce the same y value. Lots of functions do that. (you'll study parabolas pretty soon and all that open up or down have two x values producing the same y value).
If you have a member of the domain producing 2 y values, that doesn't work. That would not be a function.
This example is a function.

plz quick solve for f
Answer: f = 100
Step 1.
We'll need to expand 3(f - 91) by multiplying a term and an expression. The following product distributive property will be used: A(B + C) = AB + AC.
In the example, the expression will consist of 2 terms.
First term: 3 and f.
Second term: 3 and -91
Rewrite 3(f - 91) like this.
3f - 3 × 91
Step 2.
Multiply 3 by 91.
3 × 91 = 273
Hence, the answer is 100.

If 6.5 pounds of strawberries cost 20$ what's the unit price?
Pls I’ll give brainlyest
Answer:
should be 3.07 (when rounded to the nearest hundredth)
Step-by-step explanation:
Answer: $3.08 per pound of strawberries.
Unit price is 3.08/1
Step-by-step explanation: The unit price is how much 1 point of strawberries cost.
To find the unit price divide 20 by 6.5.
20/6.5 = about $3.08.

$750 at 6% for 18 months
Answer:
$1,560
Step-by-step explanation:
6% of $750 = $45
$45 times 18 = $810
$810 + $750 = $1,560
find the measure of angle A
Answer:
30
Step-by-step explanation:
Right angle = 90 degrees
180-90 = 90, hence the right side of the equation.
x+37+x+67 = 90
2x + 104 = 90
2x = -14
x = -7
Plug in x.
-7+37 = 30 (angle a)
Angle a = 30
Answer:
angle A = 30 degrees
Step-by-step explanation:
*All triangles have an interior angle that adds up to 180 degrees
The triangle is the picture is a right triangle so one of the angles is 90 degrees.
First, we must figure out what "x" is:
⇒ 180 = 90 + x + 37 + x + 67
Combine like terms:
⇒ 180 = 2x + 194
Subtract 231 from both sides:
⇒ 180 - 194 = 2x + 149- 194
⇒ -14 = 2x
The divide both sides by 2:
⇒ [tex]\frac{-14}{2} + \frac{2x}{2}[/tex]
⇒ -7 = x
Now, we can figure out what angle A is by taking the equation "x + 37" and subtituting x by -7:
⇒ x + 37
⇒ -7 + 37
⇒ 30
To check out answers, take all of the eqautions in the picture and subtitute x by -7, (remember that it must add up to 180):
⇒ 90 + x + 37 + x + 67 = 180
⇒ 90 + (-7) + 37 + (-7) + 67 = 180
⇒ 180 = 180
Please need help on this one h as be no clue how to do this
Answer:
y = -2x
Step-by-step explanation:
Equation in slope-intercept form is y = mx + b.
m = slope = ∆y/∆x
Using any two points on the line, say (0, 0) and (-20, 40),
Slope (m) = (40 - 0) / (-20 - 0) = 40/-20
Slope (m) = -2
b = y-intercept = the value of y when x = 0.
b = 0
To write the equation of the line, substitute m = -2 and b = 0 into y = mx + b
Thus:
y = -2x + 0
y = -2x
Ms. Hardy walks 12 meters in 24.7 seconds.
If she walks at this same rate, which of the
following is closest to the distance she will
walk in 5 minutes?
Answer:
she walks about 145.7 meters in 5 minutes
Step-by-step explanation:
Hey There!
so first we want to find the meters per second rate
to do this we do
[tex]\frac{12}{24.7} = 0.48582995951[/tex]
so the meters per second is 0.4858299591
Then we want to find how many seconds are in a 5 minutes
to do this we multiply 5 and 60
5x60=300
then we want to multiply that by the meters per second
300x 0.4858299591=145.748987854
so she walks about 145.7 meters in 5 minutes
An artical fills 1/2 of a magazine page. A corresponding photo takes up 3/8 of the article. How much of the page is taken up by the photo
Answer:
3/16
Step-by-step explanation:
If an article takes half of the page then;
1article = 1/2 of a page
3/8 of the article = x
Cross multiply
1×x = 1/2×3/8
x = 3/(2×8)
X = 3/16
Hence the photo takes 3/16 of the magazine
