Answer:
distance = 6.0 m
Step-by-step explanation:
1. Take note of the given.
Force = 50 N Work Done = 300 J m = ?
2. Write the formula.
J = Nm
3. Substitute.
300 J = (50N)(m)
4. Divide both sides by 50 N to isolate m.
300 J / 50 N = m
6 = m

Answer:
[tex]\sqrt{170}[/tex]
Step-by-step explanation:
(x2 - x1)^2 + (y2-y1)^2 = c^2
(6 - - 5)^2 + (-3 - 4)^2 = c^2
121 + 49 = c^2
170 = c^2
[tex]\sqrt{170}[/tex] which is about 13.04
Find the following, giving your answers to 1 decimal place?
Answer:
I. Volume = 301.6 cm³ (to 1d.p)
II. CSA = 188.5 cm² (to 1d.p)
Step-by-step explanation:
Given the following data;
Height, h = 8cm
Radius, r = 6cm
Curved length = 10cm
a. To find the volume of the cone
[tex] V = \frac{1}{3} \pi r^{2}h[/tex]
Where;
V is the volume of the cone.r is the radius of the base of the cone.h is the height of the cone.Substituting into the equation, we have;
[tex] Volume = \frac{1}{3} * 3.142*6^{2}*8 [/tex]
[tex] Volume = \frac{1}{3} * 3.142*36*8 [/tex]
[tex] Volume = 3.142*12*8 [/tex]
Volume = 301.6 cm³ (to 1d.p)
b. The curved surface area of the cone
[tex] CSA = \pi rl[/tex]
Where;
CSA is the curved surface area of the cone.r is the radius of the base of the cone.l is the curved length of the cone.Substituting into the equation, we have;
[tex] CSA = 3.142*6*10 [/tex]
CSA = 188.5 cm² (to 1d.p)

1. Candace has $15 more than Amar. Their combined money totals $85. Which system of equations represents this situation? F. c + a = 85 G. c + a = 85 H. c – a = 85 I. c – a = 85 c – a = 15 a + c = 15 c – a = 15 c + a = 15 Also please show explanation
The system of equations that represents Candace's and Amar's combined money is c + a = 85.
What is a linear equation?
A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given, Candace has $15 more than Amar.
Assuming Amar has $a.
∴ Candace(c) has $(x + 15).
Their combined money totals $85.
So, the equation that represents their combined money is
x + (x + 15) = 85 or a + c = 85.

A. Nothing needs to be done, since they both equal have 2’s and 3’s for coefficients.
B. Multiply the first equation by 3 and the second equations by 2.
C. Multiply the first equation by 2 and the second equation by 3.
D. Multiply the first equation by 3.
Answer:
The answer is C.
Step-by-step explanation:
I did the test and got it right. :)
The correct is C = Multiply the first equation by 2 and the second equation by 3.
What is system of equations by elimination?The elimination method exists utilized to solve a system of linear equations. It is the most widely used and simple method as it concerns fewer calculations and steps. In this manner, we eliminate one of the two variables and test to solve equations with one variable.
if we'll multiply the first equation by 2 and second by 3 we will be able to solve the equation by elimination.
(-3x+2y=16) X 2 = -6x + 4y = 32
(2x+5y=21) X 3 = 6x + 15y = 63
the coeffients of x gets cancelled out on adding the new equations
4y+ 15y = 32+ 63
19y = 95
y= 95/19

A company has two manufacturing plants with daily production levels of 7x+19 items and 5x−2 items, respectively. The first plant produces how many more items daily than the second plant?
Answer:
The first plant manufactures 2x + 21 more items daily.
Step-by-step explanation:
Given that:
Production level of plant one = 7x + 19
Production level of plant two = 5x -2
To find the number of items first plant manufactures more than second plant, we will find the difference between production levels.
Difference = (7x + 19) - (5x - 2)
Difference = 7x + 19 - 5x + 2
Difference = 2x + 21
Hence,
The first plant manufactures 2x + 21 more items daily.
