help i really need it :(
Answer:
The correct equation is [tex]2\frac{2}{3}+r = 3[/tex].
Why?
To find the correct answer we have to isolate r from the other numbers. To isolate r from this equation, we have to subtract [tex]2\frac{2}{3}[/tex] from both sides of the equation. Remember that you can do whatever you need to one side of the equation, but you must do the exact same thing to the other side, so the equation remains the same value. By subtracting [tex]2\frac{2}{3}[/tex] from the equation, we get [tex]2\frac{2}{3}-2\frac{2}{3}+r=3-2\frac{2}{3}[/tex]. Simplify: [tex]r=\frac{1}{3}[/tex]. Therefore, answer D is the solution.
Good luck!
Can someone help me with this? I was wrong and cant figure it out
Answer:
A. 21.
Step-by-step explanation:
4x + 2 = 31 + 55 (external angle of a triangle theorem).
4x + 2 = 86
4x = 86 - 2
4x = 84
x = 84/4 = 21.
help me plz.......................
Answer:
B
Step-by-step explanation:
-16x - 32
We can factor out -16 from the -16 and -32 which leads us to this equation:
-16 (x + 2)
Meaning B would be the correct answer
Answer: B. -16(x + 2)
Step-by-step explanation:
The GCF, or greatest common factor, of -16 and -32, is -16.
Thus, distribute out -16 to get -16(x + 2)
Hope it helps :) and let me know if you want me to elaborate.

A (- 1, 3 ) → A' (- 3, 7 )
x- coordinate goes from - 1 → - 3 , that is - 2
y- coordinate goes from 3 → 7 , that is + 4
Translation rule is (x, y ) → (x - 2, y + 4 ) , then

Answer:
slope = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (4, - 18) ← 2 ordered pairs from the table
m = [tex]\frac{-18-0}{4-(-5)}[/tex] = [tex]\frac{-18}{4+5}[/tex] = [tex]\frac{-18}{9}[/tex] = - 2

Rickets Vitamin D is essential for strong, healthy bones. Our bodies produce vitamin D naturally when sunlight falls upon the skin, or it can be taken as a dietary supplement. Although the bone disease rickets was largely eliminated in England during the 1950s, some people there are concerned that this generation of children is at increased risk because they are more likely to watch TV or play computer games than spend time outdoors. Recent research indicated that about 20% of British children are deficient in vitamin D. Suppose doctors test a group of elementary school children.
a) What’s the probability that the first vitamin D– deficient
child is the eighth one tested?
b) What’s the probability that the first 10 children tested
are all okay?
c) How many kids do they expect to test before finding
one who has this vitamin deficiency?
d) They will test 50 students at the third-grade level. Find
the mean and standard deviation of the number who
may be deficient in vitamin D.
e) If they test 320 children at this school, what’s the
probability that no more than 50 of them have the vita- min deficiency?

Our wide range of vitamins, minerals and health supplements help to ensure you’re getting the nutrients you need every day. From chewable vitamins to food supplements, hair vitamins to vitamins for skin and folic acid.

A builder is buying boxes of nails. She has $187 to spend and each box of nails costs $4.
Answer:
46 boxes of nails
Step-by-step explanation:
She has $187 to spend, the maximum.
187/4 = 46.75
Since she cannot buy 0.75 of a box of nails, she can only buy 46. So she is left with an extra $3 and buys 46 boxes of nails.

What is the quotient of 1.155 x 10^5 and 1.65 x 102 expressed in scientific
notation?
Answer: 7.00x10^2
Step-by-step explanation:
Are you asking for the quotient of (1.155 x 10^5)/(1.65 x 10^2)?
If so, divide (1.155/1.65) = 0.7000.
Then subtract 2 (the bottom exponent from [tex]10^{2}[/tex]) from the top exponent: [tex]10^{5}[/tex] becomes [tex]10^{3}[/tex].
Combine the two: 0.7000x10^3
Move the decimal point to the right by one: 7.00x10^2 (to 3 sig figs).
7 x 10² is the quotient of 1.155 x 10⁵ and 1.65 x 10² expressed in scientific
notation.
To find the quotient of these two numbers in scientific notation, you divide the two significant figures and then subtract the exponents of 10. The calculation would be as follows:
(1.155 x 10⁵) / (1.65 x 10²)
Dividing the significant figures:
1.155 / 1.65
= 0.7
Subtracting the exponents:
5 - 2 = 3
So, the quotient in scientific notation is approximately:
0.7 x 10³
Which can also be written as:
7 x 10²
Hence, the quotient of 1.155 x 10⁵ and 1.65 x 10² expressed in scientific
notation is 7 x 10².

An infant drinks about 30 ounces of milk per day. About how many quarts of milk does the baby drink in 4 weeks
Answer:
840 Ounces
Step-by-step explanation:
4 weeks has 28 days. { 4 * 7 = 28 }
because an infant eats about 30 ounces of milk per day.
So 30 * 28 = 840 ounces
The baby drank about 840 ounces in 4 weeks.
The number of quarts of milk drank by baby in 4 weeks is 26.25 quarts.
Given that, an infant drinks about 30 ounces of milk per day.
What is metric conversion?Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
Here, number of days in 4 weeks = 4×7
= 28 days
Number of ounces of milk drank by infant
= 28×30
= 840 ounces
We know that, 32 ounces = 1 quarts
So, 840 ounces = 840/32
= 26.25 quarts
Therefore, the number of quarts of milk drank by baby in 4 weeks is 26.25 quarts.

Answer:
115°
Step-by-step explanation:
Since ∠ACM and ∠ACE form a straight line that means that they are supplementary (they add up to 180°). So, if m∠ACB is 65°, then m∠ACE is 180° - 65° which is 115°
Answer:
115
Step-by-step explanation:
[tex]fca + acb + bcd = 180 \\ 90 + 65 + bad = 180 \\ bad = 25 \\ \\ bad = fce \\ fce = 25 \\ \\ ace = acf + fce \\ = 90 + 25 \\ = 115[/tex]

Marlee has to find the point that divides the line segment between the points P(-6, 10) and R(2, -4) exactly in half. Marlee states: "the answer is M(-2, 3). Since a midpoint divides a line segment into 2 equal parts, I used the midpoint formula." Is this a logical argument?
Please choose one of these choices.:
A. Yes; using the midpoint formula will determine the middle point of a line segment.
B. No; she should have used the distance formula.
C. No; she should have used the quadratic formula.
D. No; she should have used the slope-intercept formula y = mx + b.
Answer:
A.
Step-by-step explanation:
If you use the points P(-6,10) and R(2,-4) and put them it the midpoint formula you would get (-2,3) therefore it would be logical to use it
