Answer:
Slope of the line is -1.2
Option B is correct option.
Step-by-step explanation:
We need to find slope of the line with given points (4, 10.5) and (8,5.7)
The formula used to calculate slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points given are: (4, 10.5) and (8,5.7)
We have [tex]x_1=4,y_1= 10.5x_2=8,y_2=5.7[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{5.7-10.5}{8-4}\\Slope=\frac{-4.8}{4}\\Slope=-1.2[/tex]
So, Slope of the line is -1.2
Option B is correct option.
A card has p meters of lace edging wound on it. Nerys buys n lengths of edging, each x cm long. If Q meters of edging are left on the card, find a formula for Q in terms of P, n and x
Answer:
Q = P - n(x/100)
Step-by-step explanation:
P is the total number of lace edging, n is the number of times the length x is cut from P, and Q is the remnant of the reduction.
So the number of x length is subtracted from P and must be converted to meters (since it is in centimeters) to get Q. That is;
Q = P - n(x/100)

1. Lirio is exerting a force of 89 N on a nice boulder in her swamp. The nice boulder is 68 kg. What is the acceleration of the nice boulder?
2. If Renae has a mass of 85 kg, and you exert a force of 45N on her, what would her acceleration be?
CAN I PLEASE GET HEPL ON THESE 2 I NEED TO KNOW THE EQUATIONS!!!
Answer:
Step-by-step explanation:
1.
F=ma
89=68a
a=89/69 units/s²
2.F=ma
45=85 a
a=45/85=9/17 units/s²
Problem 1
Answer: Approximately 1.3 m/s^2
---------------
Work Shown:
We'll use the formula F = m*a, which is from Newton's second law.
The force applied is F = 89 newtons. The mass of the boulder is m = 69 kilograms. This means,
F = ma
89 = 69*a
a = 89/69
a = 1.28985507246377
a = 1.3
I rounded to 2 sig figs because the other given values (89 and 69) are to 2 sig figs as well.
=================================================
Problem 2
Answer: Approximately 0.53 m/s^2
---------------
Work Shown:
We'll follow the same idea as problem 1
This time we are given F = 45 and m = 85
So,
F = ma
45 = 85*a
85a = 45
a = 45/85
a = 0.52941176470589
a = 0.53
The acceleration is roughly 0.53 m/s^2, which means that for every second, the speed is increasing by roughly 0.53 m/s.
what is the median of the following 9 numbers 23,15,32,27,19,22
22.5 i think but i have no idea good luck
The median of the following 9 numbers 23,15,32,27,19,22 is 22.5.
What is median?The median is the value that splits the mathematical numbers or expressions in the half. The median value is the middle number of data point. to find the median firstly arrange the data points in ascending order.
Arrange the data points from smallest to largest;
15, 19, 22, 23, 27, 32.
Total number of data points is 6. And 6 is the even number.
So median of even numbers of data points is average of two middle points.
And those numbers are 22 and 23.
Average of 22 and 23 is (22 + 23) / 2 = 22.5
Therefore the median is 22.5.

there are 800 ppl who 50% of them use english 30% use spanish 15% vianameese 5% other
how many people use each language?
(WORK whoever shows the best work gets brainiest reported if no work!)
Answer:
400 people english, 240 spanish, 120 vietnamese and 40 other
Step-by-step explanation:
50% is half of 800.
half of 800 is 400. 400 use english
to find 10 percent, you divide by 10. to find 30, you multiply that by 3.
80 times 3 is 240. 240 use spanish.
15 percent is 10 percent, which is 80, +40 because of the 5 percent
80+40 is 120. 120 use vietnamese.
5 percent is half of ten percent.
half of 80 is 40.
and it all adds up to 800

The graph of a line on a coordinate plane has a slope of 1/2 and passes through the point (4, -3). Which equation describes the line?
Answer:
[tex]\boxed {\boxed {\sf y= \frac{1}{2}x-5 }}[/tex]
Step-by-step explanation:
Since we are given a point and a slope, we should use the point-slope equation.
[tex]y-y_1=m(x-x_1)[/tex]
where m is the slope and (x₁, y₁) is the point the line passes through.
We are given the slope of 1/2 and the point (4, -3). Therefore:
[tex]m= \frac{1}{2} \\x_1= 4\\y_1= -3[/tex]
Substitute the values into the formula.
[tex]y--3= \frac{1}{2} (x-4)[/tex]
[tex]y+ 3= \frac{1}{2} (x-4)[/tex]
Distribute the 1/2. Multiply each term inside the parentheses by 1/2.
[tex]y+3= \frac{1}{2} *x + \frac{1}{2} * -4[/tex]
[tex]y+3=\frac{1}{2}x-2[/tex]
We want to the equation of the line in slope-intercept form or y=mx+b. We need to isolate y. 3 is being added and the inverse of addition is subtraction. Subtract 3 from both sides of the equation.
[tex]y+3-3=\frac{1}{2}x-2-3[/tex]
[tex]y=\frac{1}{2}x-2-3\\y= \frac{1}{2}x-5[/tex]
The equation of the line is y=1/2x-5

En una papelería sé adquirieron un paquete de 36 plumas este tiene un valor de 97.5 ¿Si el que compró el paquete va a vender cada pluma 75 centavos más cara cada pluma en cuanto La vendera?
Responder:
3,46
Explicación paso a paso:
Número de lápices comprados = 36
Costo total de los 36 lápices = 97,5
El precio unitario de cada lápiz será:
Costo total / número de lápices
97,5 / 36
= 2.708
El precio de venta por lápiz será:
Precio por lápiz + 75 céntimos
2,708 + 0,75
= 3.458
= 3,46
Por tanto, el precio de venta por lápiz será 3,46.

What is a unitary method ?In simple terms, the unitary method is used to find the price of a single unit from a given multiple.
Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that there are 19 nickels, let n=number of nickels.
The number of total coins subtracted by number of nickels will give us the number of dimes.
The Value of dimes=10(number of dimes) or total value of dimes/individual value (10cent)
Then we can substitute total as $1.65 and get the value of nickels by multiplying by 5cent
Since the value of the dimes is the value of nickels subtracted from the total, we can subtract 95 from 165 and divide the difference by 10, to get the number of dimes.
5(n)=5(19)=95
(165-95)/10 =number of dimes
70/10 = 7dimes
