Answer:
10.54 kg
Step-by-step explanation:
Given that :
Half of blueberries is served with breakfast
The remaining 5270g is served with dinner
How many kilograms of blueberries did the science camp start with :
Total grams of blue berries :
(Grams served at breakfast + grams served at dinner)
Let total blueberries = x
x/2 + 5270 = x
(x + 10540) /2 = x
x + 10540 = 2x
10540 = 2x - x
x = 10540 grams
Amount of kilograms science camp started with = (10540) / 1000 = 10.54 kg

What is the solution to the linear equation 4b + 6 = 2 - b+ 4
Final Answer: [tex]b = 0[/tex]
Steps/Reasons/Explanation:
Question: What is the solution to the linear equation [tex]4b + 6 = 2 - b + 4[/tex]?
Step 1: Simplify [tex]2 - b + 4[/tex] to [tex]6 - b[/tex].
[tex]4b + 6 = 6 - b[/tex]
Step 2: Cancel [tex]6[/tex] on both sides.
[tex]4b = -b[/tex]
Step 3: Subtract [tex]-b[/tex] from both sides.
[tex]4b + b = 0[/tex]
Step 4: Simplify [tex]4b + b[/tex] to [tex]5b[/tex].
[tex]5b = 0[/tex]
Step 5: Divide both sides by [tex]5[/tex].
[tex]b = 0[/tex]
~I hope I helped you :)~
Answer:
b = 0
Step-by-step explanation:
(Combine like terms): 4b + 6 = 2 - b + 4
4b + 6 = 6 - b
(Use Addition property of
equality to add b): 4b + b + 6 = 6
5b + 6 = 6
(Use Subtraction property of
equality to subtract 6): 5b + 6 - 6 = 6 - 6
5b = 0
(Divide both sides by 5): 5b = 0

b = 0$10,000 down payment for your house if you can invest 2% of your monthly income (yearly income: $67,705) into an account that earns 4% quarterly. Also what is the formula for this? Is it compounded quarterly?
Answer:
the future value of each deposit = ($67,705 x 1/12 x 0.02) x (1 + 1%)ⁿ = $112.84 x 1.01ⁿ
where n = number of quarters (interest is compounded quarterly)
the effective interest = 1.01⁴ - 1 = 4.06%
Assuming that you are going to make monthly payments, then you would need the number of quarters (n) in order to determine the future value. Since the interest is compounded quarterly, each contribution = $112.84 x 3 = $338.52
For example, if you are planning to save money for 5 years (n = 5 x 4 = 20), then the future value of the investment = $338.52 x 22.019 (FV annuity factor, 1%, 20 periods) = $7,453.87
if you want to calculate the total number of contributions (n):
FV annuity factor, 1%, n? = future value / contribution = $10,000 / $338.52 = 29.5404
since you know the interest rate (1%) you have to look at a future value annuity table and search the n for 29.54. This is approximately 26 periods (FV annuity factor = 29.53).

Which of the following is true about similar figures?
All similar figures are congruent.
If two figures are not similar, they can still be congruent.
All congruent figures are similar.
If two figures are not congruent, they can't be similar.
Answer:
All congruent figures are similar
Step-by-step explanation:
Congruent means "same" in mathematics and you have evidence to prove it. You can look at two puppies with the exact same fur color and be like "yeah they're the same". If they are the same size and shape they're congruent. This is why the AAA postulate can't work because triangles can have the same angles yet be different sizes. If figures are not congruent, they can't be similar and figures that aren't similar can't be congruent either.
All similar figures are congruent is true about similar figures
What is congruency?We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.
In mathematics, congruent means identical, and you can cite examples to support your claim.
just by looking at them. They are congruent if their dimensions match. Triangles can have the same angles but differ in size, which makes the AAA postulate invalid.
If two figures are not similar, they cannot be congruent, therefore similarly unrelated figures cannot be congruent.

The volume of a rectangular prism whose dimensions are binomials with integer coefficients is modeled by the function V(x) = x^3 − 14x^2 + 49x − 36. Given that x − 1 and x − 9 are two of the dimensions, find the missing dimension of the prism.
Answer:
The missing dimension of the prism is (x-4)
Step-by-step explanation:
Here, we want to find the missing dimensions of the prism
To get the volume, we are to multiply three dimensions since we are talking about volume
Mathematically, to find the third dimension, we need to divide the original polynomial by the product of the two other dimensions
The product of the two other dimensions is;
(x-1)(x-9) = x^2-9x-x + 9
= x^2-10x+ 9
So we divide;
(x^3-14x^2+49x-36)/(x^2-10x+ 9)
We can use long division to get this
using long division, the answer here is x-4
The volume of a prism is the product of its dimensions.
The missing dimension of the prism is x - 4
The volume function is given as:
[tex]\mathbf{V(x) = x^3 - 14x^2 + 49x - 36}[/tex]
Let the missing dimension of the prism be y.
So, the volume is calculated using:
[tex]\mathbf{V(x) = y \times (x - 9) \times (x -1)}[/tex]
Multiply the factors
[tex]\mathbf{V(x) = y \times ( x^2-9x-x + 9)}[/tex]
[tex]\mathbf{V(x) = y \times ( x^2-10x + 9)}[/tex]
Equate both expressions of volume
[tex]\mathbf{y \times ( x^2-10x + 9) = x^3 - 14x^2 + 49x - 36}[/tex]
Make y the subject
[tex]\mathbf{y = \frac{x^3 - 14x^2 + 49x - 36}{x^2-10x + 9 }}[/tex]
Factor the numerator
[tex]\mathbf{y = \frac{(x - 4)(x^2-10x + 9 )}{x^2-10x + 9 }}[/tex]
Cancel out common factors
[tex]\mathbf{y = x - 4}[/tex]
Hence, the missing dimension of the prism is x - 4

Maria takes 2 hours to plant 50 flower bulbs. Lois takes 3 hours to plant 45 flower bulbs. Working together, how long should it take them to plant 150 bulbs?
Answer:
Maria: (50 bulbs)/(2 hours) = 25 bulbs/hour
Lois: (45 bulbs)/(3 hours) = 15 bulbs/hour
Together: 25 + 15 = 40 bulbs/hour
(150 bulbs)/(40 bulbs per hour) = 3 3/4 hours
(3/4 hours)(60 minutes/hour) = 45 minutes
Total time: 3 hours 45 minutes

Answer:
The final score of Roger is 22.
Step-by-step explanation:
The final score (F) of Roger is given by:
[tex] F = 5R - 2W [/tex]
Where R is the right answers and W is the wrong answers
Since he gets 6 questions correct (R = 6) and 4 question wrong (W = 4) we have:

Tell whether the following equation has one, zero, or infinitely many solutions. 2(4x + 10) = 8x + 20. Group of answer choices:
A) Infinitely many solutions
B) One solution
C) Zero solutions
Answer:
The equation will have infinitely many solutions.
Option A is correct
Step-by-step explanation:
We need to tell if the equation [tex]2(4x + 10) = 8x + 20[/tex] has one, zero, or infinitely many solutions.
First we solve the equation to find the value of x
[tex]2(4x + 10) = 8x + 20[/tex]
First multiply 2 with terms inside the bracket
[tex]8x+20=8x+20[/tex]
Now Subtract 20 from both sides
[tex]8x+20-20=8x+20-20[/tex]
[tex]8x=8x\\0=0[/tex]
So, the equation will be true for all values of x
As after solving the equation we get 0=0 so, the equation will have infinitely many solutions.
Option A is correct
