A box is pulled to the right with a force of 65 N at an angle of 58 degrees to the horizontal. The surface is frictionless. The free body diagram is shown.
A free body diagram with 3 force vectors. The first vector is pointing north, labeled F Subscript N Baseline, the second vector is pointing south labeled F Subscript g Baseline = 30 N, and the third pointing 58 degrees north of east labeled F Subscript g Baseline = 65 N.
What is the net force in the x-direction?
30 N
34 N
55 N
65 N
Answer:
34 N.
Step-by-step explanation:
Net force in x direction = 65 cos 58
= 34 N.

0.5y+7=5(0.2+1.5y) someone please help I got y=1.36 but its wrong
Answer:
y= 6/7
Step-by-step explanation:
0.5y + 7 = 5( 0.2 + 1.5y )
Get rid of the brackets first
0.5y + 7 = 1 + 7.5y
Move the like terms
0.5y + 7 - 7.5y = 1
0.5y - 7.5y = 1 - 7
Collect the like terms
-7y = -6
Divide both sides by -7 to get y on its own
y= -6/-7
A negative number divided by a negative number gives a positive number so
y = 6/7
Answer:
y=6/7 or 0.857 aprox.(0.86)
Step-by-step explanation:
[tex]0.5y+7=5(0.2+1.5y)[/tex]
[tex]0.5y+7=1+7.5y[/tex]
[tex]7.5y-0.5y=7-1[/tex]
[tex]7y=6[/tex]
[tex]y=6/7= 0.857[/tex]

A cheetah runs 296 feet in 4 seconds. How far could a cheetah run in 10
seconds at this rate?
Answer:
740 feet
Step-by-step explanation:
The speed of the cheetah is 74 feet per second:
speed = distance ÷ time
= 296 ÷ 4 = 74 feet per second
In 10 seconds:
distance = speed × time
= 74 × 10
= 740 feet
Answer:
740 Feet
Step-by-step explanation:
Given: 296 ft= 4 sec
To Find: 10 sec = [tex]\left[?}\right][/tex] ft
First we need to Find How many feet are in 1 second.
To find that,
Do 296 divided by 4
=
74
So 1 second = 74 Feet.
Then 74 ft Times 10 second
Which gives you
740 Feet.
Therefore, at 10 second rate gives you 740 Feet.

One example of a mathematical model is an equation that describes the relationship between two quantities.
a. True
b. False
Answer:
True
Step-by-step explanation:
Linear equations are often used to model the relationship between the dependent variable that is affected by changes in the independent variable.
For instance, the linear function: f(x) = 2x + 3, where f(x) is the output (dependent variable) depends on the value of the input, x (independent variable).
Therefore, the correct answer is True.

Using the information given above, the sampling distribution of the sample proportion of 100-ohm gold-band is 2.
Sampling distribution of proportion, P = 2% = 0.02 Sample size, n = 100The sampling distribution of the sample proportion can be calculated thus:
Distribution of sample proportion = npDistribution of sample proportion = (100 × 0.02) = 2
Therefore, there is a probability that only 2 of the samples will have resistances exceeding 105 ohms.

7 is the constant
please help I dont understand
Step-by-step explanation:
When it says y varies directly with x it just means that y and x are proportional/equal to each other. The constant of variation and the constant of proportionality are the same thing just different way of saying it so they can confuse you and make your life miserable. Since y and x are proportional to each other and the constant of proportionalty is -5 to make an equation that represents a line you use the formula y=mx+b. That is the slope of the line. With that formula let's first plus in the x so we have y=m2+b. The formula for direct variation is y=kx as well that's good to know and it's good to memorize all these formulas. Math becaomes easier when you have the process down pat and you just need to plug numbers into different equations, expressions, and scenarios. Do m = [y1 - y2] / [x1 - x2] and you'll get the answer.

Answer:
B = x = 44 degrees
Step-by-step explanation:
Interior angles of a triangle = 180 degrees.
There are 2 congruent sides so the angle to the right of 67 degrees is also 67 degrees
180 - 2(67) = 46 degrees (the third angle of the triangle)
x + 46 degrees = 90 degrees ( complementary angles)
x = 44 degrees

Lakeside amusement park charges an entry fee plus $1.50 per ticket used to go on the rides. The entry fee is the same amount for everyone. Louisa spent a total of $30.75 on the entry fee plus 15 ride tickets. Click “show your work” below and show calculations to determine how much Louisa paid for the entry fee.
Answer:
The entry fee is $8.25
Step-by-step explanation:
Total together: $30.75
She bought 15 tickets * $1.50 cost per 1 ticket
= $22.50
$30.75 (total) - $22.50 (price of tickets)= $8.25

The function g(x) is a transformation of the quadratic parent function, f(x) =
x2. What function is g(x)?
a. g(x) = 1/2x^2
b. g(x) = -2x^2
c. g(x) = 2x^2
d. g(x) = -1/2x^2
The function g(x) is a transformation (flipped upside down and horizontally stretched) of the quadratic parent function, f(x) = x2. g(x) = -0.5x².
What is flipping upside down?Flipping upside down, is found by taking the negative of the original function; that is, the rule for this transformation is −f (x).
Since, g(x) is an upside down function of f(x), g(x) = -f(x).
What is stretching a graph?If we multiply a function by a coefficient, the graph of the function will be stretched.
A function h(x) represents a horizontal compression of f(x) if h(x) = f(cx) and c > 1.
A function h(x) represents a horizontal stretch of f(x) if h(x) = f(cx) and 0 < c < 1.
Since, g(x) is clearly a stretched transformation of f(x), c < 1.
The possible function g(x) = -0.5x².

Jimmy wants to enlarge a sign for his taco stand. He increases the height by a scale factor of 4 and the width by a factor of 2. What is the effect on the area of the sign? times greater
After the increase in the dimensions of the sign, the effect on the area of the sign is that the new area is 8 times larger than the initial area.
The sign has the shape of a rectangle. A rectangle has four sides. The opposite sides are equal in length.
The area of a rectangle = length x width.
Jimmy is making the sign bigger by increasing the size of the length and width. Let's imagine that the width is 8cm and the length is 10cm.
The initial area of the sign = 10 x 8 = 80 cm
After the increase in the dimensions, the length is are 40cm and 16cm for the width.
New area = 40 x 16 = 640
Number of times the new area is greater than the initial area = 640 / 80 = 8 times larger
