113 N
Explicación paso a paso:
Las fuerzas ejercidas se dan como:
F1 = 30 N
F2 = 45 N
F3 = 38 N
A partir de los valores de las fuerzas ejercidas, podemos observar que todas las fuerzas están en la misma dirección; Dado que la fuerza total ejercida es un sol de las 3 fuerzas:
F1 + F2 + F3
(30N + 45N + 38N) = 113 N
How much sales tax would you pay for a $55 pair of roller blades if the tax rate is 6.625%?
Answer:
419 or 419.37
Step-by-step explanation:
55 x 6.625 = 364.375
364.375 = 364.37 (Rounded to the Nearest 10)
55 + 364.37 = 419.37

Melanie invested $3800 in an account paying in interest rate of 2 3/8% compounded quarterly Sebastian invested $3800 in an account paying in interest rate of 2 3/4% compounded monthly after 16 years how much more money with Sebastian have in his account then Melanie to the nearest dollar
Answer:
$317
Step-by-step explanation:
Formula for compound interest is;
A = P(1 + (r/n))^(nt)
For melanie;
P = $3800
r = 2⅜% = 0.02375
n = 12/4 = 3
t = 16 years
Thus;
A = 3800(1 + (0.02375/3))^(3 × 16))
A ≈ $5548
For Sébastien;
P = $3800
r = 2¾% = 0.0275
n = 12
t = 16
Thus;
A = 3800(1 + (0.0275/12))^(12 × 16))
A ≈ 5865
Difference between Sébastien and Melanie's final amount = $5865 - $5548 = $317
Find the measure of the arc or central angle indicated by the question mark. Assume that lines which appear to be diameters are actually diameters. PLEASE HELP AND SHOW WORK
Answer:
The measure of the arc length is 62 degrees
Step-by-step explanation:
Here, we want to find the given arc measure
Mathematically, we are going to use the angle arc relationship
For the angle arc relationship, the measure of the central angle is simply the measure of the arc
In this case, the central angle is 62: this means that the given arc measure is 62 degrees too

Help me if you are good at finding areas please? A sticker on the rear window of a truck is rectangular in shape with two green triangular sections, as shown below. The two triangles are similar. If AB = 12 cm, BC = 6 cm, and EF = 4.5 cm, what is the total area for both triangles? (Check the picture)
Answer:
[tex]\frac{x}{y}[/tex]45 long
Step-by-step explanation:
The total area of both the triangles is 56.25 square units.
What is the scale factor of similar triangles?When two triangles are similar, the reduced ratio of any two corresponding sides is called the scale factor of the similar triangles.
What is area?The space occupied by a flat shape or the surface of an object is called area.
What is the formula for area of triangle?Area = (1/2) × base × height
According to the given question.
We have a two triangles, which are similar to each other.
Let the length of the side DE in triangle DEF be x.
Since, ABC similar to DEF
⇒[tex]\frac{AB}{DE} =\frac{BC}{EF}[/tex]
⇒[tex]\frac{12}{x} =\frac{6}{4.5}[/tex]
⇒[tex]\frac{12(4.5)}{6} = x[/tex]
⇒[tex]2(4.5)=x[/tex]
⇒ [tex]x = 9[/tex]
Now, area of triangle ABC = [tex]\frac{1}{2}(6)(12)=36 square units[/tex]
Area of triangle DEF = [tex]\frac{1}{2} (9)(4.5)= 20.25square units[/tex]
Therefore,
The total area for both the triangles
= 36 + 20.25
= 56.25 square units
Thus option B is correct.

3(x+8)2 + 8 = 83
3(x+8)2 = 75
Step 1
(x + 8)2 = 225
Step 2
X + 8 = +15
Step 3
X = 7 or x = -23 Step 4
Answer:
Step-by-step explanation:
I think you mean 3(x+8)², not 3(x+8)2. If you cannot type ², use ^ to mark the exponent: 3(x+8)^2.
3(x+8)² + 8 = 83
3(x+8)² = 75
(x+8)² = 25
x+8 = ±√25
x+8 = ±5
x = -8 ± 5 = -3, -13

Tina paid $6.60 for some $0.15 stamps and some $0.20 stamps. She bought 37 stamps in all. How many of each kind did she buy?
PLS HELP I WILL GIVE BRAINLIEST
Answer:
Let n be the number of 25 cent stamps.Then, 28 - n must be the number of 29 cent stamps.Tim paid $7.60 the stamps.
0.25n + 0.29(28 - n) = 7.60
This means that n stamps at 25 cents a piece plus (28 - n) stamps at 29 cents a piece sum to $7.60.Solve for m.
0.25n + 8.12 - 0.29n = 7.60
-0.04n = -0.52
n = 13
So, Tim bought 13 25-cent stamps and 28 - 13 = 15 29-cent stamps

Answer: 16,21
Step-by-step explanation:
There are two ways you can solve this problem using substitution and elimination.
In this answer, I'm going to be using substitution.
First, you make two equations based on the information given.
The two equations are 0.15x+0.2y=6.6 and X+Y=37.
In the second problem subtract y to move it to the other side to get X=37-y.
Now that you got x= make a new equation which should be 0.15(37-y)+0.2y=6.6 use distributive property to get 5.55-.15y+0.2y=6.6.
Then, subtract 5.55 by 6.6 to get 1.05 and 0.2y+-.15y to get 0.05 y.
Now you have 0.05y=1.05 divided 0.05 and 1.05 to get 21.
Now plug 21 into the X+Y=37 equation to get X+21=37 subtract 21 from 37 to get X=16.
So X=16 and Y=21, so the answer is 16,21.

What is the value of s? Uhm uh why is this so difficult.
Answer:
s = 47
Step-by-step explanation:
The measure of the exterior angle of a triangle is equal to the sum of the opposite interior angles
s+45 = s+6 + s-8
Combine like terms
s+45 = 2s-2
Subtract s from each side
s+45-s =2s-2-s
45 =s-2
Add 2 to each side
45+2 = s-2+2
47 =s

To prepare for a bake-off, Amy used 0.64 kilograms of flour each day for 3 weeks. How many grams did Amy use in those 3 weeks?
1 kg = 1,000 g
Answer: 13440 grams
Step-by-step explanation:
Since 1 kg is 1000 g, multiply 0.64 by 1000 to find how many grams are in a kilogram.
0.64x1000
=640 grams
She uses 640 grams each day.
How many grams does he use in 3 weeks?
1 week has 7 days
3 weeks has 21 days
3x7=21
640x21
