Answer:
294lbs
Step-by-step explanation:
You can find the weight by taking 10% of 280. (Move the decimal one spot to the left) That would be 28. Then divide 28 by 2 and you get 14, which would be 5%. Then add 14 to 280 and you get 294.
find the slope of y=5/4x-1
Answer:
slope = [tex]\frac{5}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{5}{4}[/tex] x - 1 ← is in slope- intercept form
with slope m = [tex]\frac{5}{4}[/tex]
Answer:
x=4/5 or x=0.8 they are the same thing

i need help with 2: simplify algebraic expressions
Answer:
a). 11x²
b). 6x + 5y
c). -4x - 20
Step-by-step explanation:
a). 8x² + 3x²
When you collect the like terms (8 and 3 are the coefficients of x²) and add them together, you get 11x²
b). 3x - 5x + y + 4y + 8x
Start by placing the like terms next to each other.
3x - 5x + 8x + y + 4y
Then add/subtract
6x + 5y
c). -4(x + 7) + 8
First, you have to expand the expression and then simplify.
-4x - 28 + 8
-4x - 20

Write the equation of the line, with the given properties, in slope-intercept form.
Slope = -4, through (7,4)
Answer:
Step-by-step explanation:
Slope-intercept form means the equation should be written in this manner
[tex]y=mx+c[/tex]
where m is the slope and c is the y-intercept
so lets take all the date we have to achieve it.
We have a point (7,4) and slope which is m= -4 we can substitute the slope and point in our equation and find the y-intercept .
[tex]y=mx+c\\4=(-4)(7)+c\\4=-28+c\\32=c[/tex]
so now we have our y-intercept that is c=32
now for the equation to be in the slope-intercept form we need m and c and we have both so just replace these variables with their values.
[tex]y=-4x+32[/tex]

The mean pulse rate (in beats per minute) of adult males is equal to 69 bpm. For a random sample of 162 adult males, the mean pulse rate is 69.6 bpm and the standard deviation is 11.3 bpm. Find the value of the test statistic.
Answer:
0.6758
Step-by-step explanation:
Given That:
Population Mean pulse rate (μ) = 69
Sample size (n) = 162
Sample mean (m) = 69.6
standard deviation (σ) = 11.3
Value of test statistic :
(m - μ) / (σ/√n)
(69.6 - 69) / (11.3 / √162)
0.6 / 0.8878118
= 0.6758
Triangle ABC is translated 2 units up and 4 units to the right and is then rotated 180° to
produce the image triangle A'B'C'. What are the coordinates of B' in the resulting figure?
Answer:
[tex]B' = (7,-6)[/tex]
Step-by-step explanation:
From the attachment, we have that:
[tex]A = (1,8)[/tex]
[tex]B = (-3,4)[/tex]
[tex]C = (4,-2)[/tex]
Required
Determine B'
Taking the translation one at a time:
2 units up
This implies, we add 2 to the y value of the function
[tex]B = (-3,4)[/tex] becomes
[tex]B' = (-3, 4 + 2)[/tex]
[tex]B' = (-3, 6)[/tex]
4 units right
This implies, we subtract 4 to the x value of the function
[tex]B' = (-3, 6)[/tex] becomes
[tex]B' = (-3 - 4,6)[/tex]
[tex]B' = (-7,6)[/tex]
180 degrees rotation
Here; B'(x,y) becomes B'(-x,-y)
So, the initial coordinates [tex]B' = (-7,6)[/tex]
becomes
[tex]B' = (-(-7),-6)[/tex]
[tex]B' = (7,-6)[/tex]
Hence:
The final coordinates of B' is [tex]B' = (7,-6)[/tex]

A softball team is ordering pizza to eat after their tournament. They plan to order cheese pizzas that cost $6 each and four-topping pizzas that cost $10 each. They order \large c cheese pizzas and \large f four-topping pizzas. Which expression represents the total cost of all of the pizzas they order? a \large 6c+10f b \large 6+10 c \large 6f+10c d \large c+f
Answer:
6c + 10f
Step-by-step explanation:
cheese pizzas = $6
four-topping pizzas = $10
They order large c cheese pizzas and large f four-topping pizzas
The total cost of the pizza = price *quantity of cheese pizza + price*quantity of four topping pizza
= 6c + 10f

Given the equation: 3x-4y=24
Find two solutions to the equation
Write your answers as coordinates
Answer:
Step-by-step explanation:
we can write this equation into a function to easily plug in values and find solutions
[tex]3x - 4y = 24\\4y = 3x - 24\\y = \frac{3x}{4} - 6[/tex]
now we can plug in any x value and find an appropriate y value
e.g.
x = 0, y = -6 (0, -6)
x = 4, y = -3 (4, -3) [tex]\frac{3(4)}{4} - 6 = 3 - 6 = -3[/tex]
x = 16, y = 6 (16, 6) [tex]\frac{3*16}{4} - 6 = 12 - 6 = 6[/tex]

We use mathematical operations every day to figure out the total revenue and expenses of the business, make budgets for the month or year, and measure distances.
Given
total roses = 49
divided equally in 7 friends
number of roses for each friend = 49 ÷ 7
number of roses for each friend = 7
roses combined by 3 friends = 7 + 7 + 7
roses combined by 3 friends = 21

Step by step
a(b+c) - d = e, for a
Answer:
a = [tex]\frac{e+d}{b+c}[/tex]
Step-by-step explanation:
To isolate the a, the first thing I would do is bring the d to the other side of the equation, remember to switch the sign. This would give me a(b+c) = e+d. Next, in order to get rid of the (b+c), bring it to the other side by dividing since it is attached to the a variable by multiplication. This leaves me with a = e+d / b+c. Make sure not to distribute, this would duplicate your a variable.
