Answer:
(B) 16.7 kg
Step-by-step explanation:
First, start by converting everything to kilograms (using unit converters):
[tex]250g(\frac{10^{-3}kg}{1g})=250*10^{-3}kg=0.25kg[/tex]
Then, add all the weights together:
[tex]100kg+0.25kg+150kg+0.25g=250kg+0.5kg=250.5kg[/tex]
Now, divide this number by 15 (since they are packed in 15 bags):
[tex]\frac{250.5kg}{15}=16.7 kg[/tex]
(B) 16.7 kg
Use the scale to help you solve the equation.
x + 122
334
e
Answer:
A. x = 212
Step-by-step explanation:
This scale is showing us that x + 122 is equal to 334 because the scale is balanced and we can see an equal sign (=) in the center. We will set up an equation and solve for x.
[Equation]
x + 122 = 334
[Subtract 122 from both sides]
x = 212
A. x = 212

Answer:
Step-by-step explanation:
4) A photograph costs $20, so the cost of x photographs is 20x.
Similarly, the cost of y prints is $25.
So the total cost is 20x+25y, and this has to be less than or equal to 400, so C.
5) just plug each pair in.
For example for the first option, x=5 and y=10, and since 20(5)+25(10)=100+250. which is less than or equal to 400, it works.

An arithmetic sequence has a first term equal to 8. Also, its 16th term is twice its 8th term. Find a formula for the n th term, T n , of this sequence.
Answer:
T(n) = 7+n
Step-by-step explanation:
A.P. Formula: a(n) = a + (n-1)d
Since a = 8 (given),
and we know 2*[T(8)] = T(16)
We may set up an equation to find d/
2(8+(8-1)d) = 8+(16-1)d
d = 1
Therefore, T(n) = 8 + (n-1)(1) = 7+n

Answer: A. 57 degrees
Step-by-step explanation:
If it's a right triangle, that means one of the angles is 90 degrees.
The sum of the angles in a triangle is 180 degrees.
We are given the other angle's measure as 33 degrees.
Therefore the other angle's measure is 180-90-33 = 57 degrees

you choose between red, blue, yellow or green wallpaper and purple or yellow carpet find the total number of possible outcomes when you select one color of wallpaper and one color of carpet
Answer:
8 possible outcomes
Step-by-step explanation:
I'm going to list all the possibilities and then count them up.
First Word is the wallpaper color, Second is the carpet color.
Red + Purple, Red + Yellow, Blue + Purple, Blue + Yellow, Yellow + Purple, Yellow + Yellow, Green + Purple, Green + Yellow
After counting them up, we get 8. Therefore there are 8 possible outcomes.
Another way is to multiply the possible outcomes for each event together, and you can get the total number of outcomes. For example, in this problem there is 4 wallpaper colors and 2 carpet colors, so when u multiply them u get 8 total outcomes. Hope this helped!

6. [tex]y=2(0.3)^x[/tex]
7. 3, greater than 1, growth, (0,3)
Step-by-step explanation:
General form of an exponential equation: [tex]y=ab^x[/tex]
(where a is the initial value, b is the growth/decay factor, and x is the independent variable)
If b > 1, the function represents exponential growth.
If 0 < b < 1, the function represents exponential decay.
Therefore, [tex]y=2(0.3)^x[/tex] represents an exponential decay (as 0 < b < 1)
For [tex]y=3(4)^x[/tex]
The y-intercept is when x = 0 ⇒ [tex]y=3(4)^0=3[/tex]
The value of a is 3. The value of b is greater than 1. So, the function represents exponential growth. The y-intercept is (0, 3)

When Kimchi is made, it is initially fermented for the first 3 days at a temperature of 70 degrees Fahrenheit and then immediately moved to a temperature of 50 degrees Fahrenheit for another 3 days after which it is put in a 35 degree refrigerator for 6 days. Write a step function that would model this situation, then graph.
Help please. I have to get my grade up by tomorrow. Please......
The given temperatures of 70 °F, 50 °F, and 35 °F, at the given 3, 3, and
6 days give the following step function;
[tex]\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}[/tex]
Please find attached the graph of the step function?How can the step function be written?The temperature at it is fermented in the first three days = 70 °F
From day 3 to 6 the temperature = 50 °F
From day 6 to day 12, the temperature at which it is kept in the freezer = 35 °F
The step function is therefore;
[tex]\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}[/tex]

Kayla’s cell phone plan charges a fee of $25 per month and $0.25 per minute. She just received a notice that the fee is being increased to $35 per month. Which equation models her new cell phone plan?
If the plan is monthly, x is equal to minutes, and y is equal to total cost, then the following is true:
Answer:
C: y = 0.25x + 35
Step-by-step explanation:
Every minute $0.25 is added, so if x is equal to minutes, then part of our equation will be 0.25x.
If the plan is monthly, then every month there will be a $35 dollar fee. This can be represented by + $35.
Lastly, y is the total cost so the equation will be set equal to y.
Anna is following this recipe to make biscuits.
Anna uses 630 g of sugar.
How many grams of chocolate will she need?
Recipe: Makes 24 biscuits
225 g oats
105 ml syrup
90 g sugar
100 g margarine
60 g chocolate
Answer:
420
Step-by-step explanation:
If anna uses 630 g of sugar it means she will make 7 batches of biscuits.
630/90=7.
In one batch she uses 60 g of sugar if she's making 7 batches of biscuits she needs 420 g of chocolate.

Compare lengths & find scale factor (s.f)
We've got base lengths, that's what we will use to find the scale factor.
27.3 ÷ 15.6 = 1.75 s.f
We're going from big triangle, to small; so, divided by 1.75s.f to find length of u
56 ÷ 1.75 = 32
U= 32m
