Answer:
B) 2%
Step-by-step explanation:
The simple interest formula is ...
I = Prt
Interest I is earned on principal P when it is invested at rate r for t years.
Filling in the given values, we can solve for r:
200 = 2000r(5)
200/10000 = r = 2/100 = 2%
The interest rate is 2%.

Tutu and Pete go hiking. Tutu brings 7/10 liter of water. Pete brings 500 millimeters of water. How many more millimeters of water did tutu bring than Pete?
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
1 liter of water equals 1000 milliliters.
To find who has more water, you need to convert (the unit) of each person to either liters or milliliters.
Since it asks for millimeters, I'm going to convert Tutu's 7/10 liters to milliliters. Since there are 1000 milliliters in every liter, you have to multiply 7/10 by 1000. 7/10 multiplied by 1000 is 700.
So Pete has 500 milliliters of water and Tutu has 700 milliliters of water.
Now you need to find the difference of 700 and 500 by subtracting.
700-500=200
Tutu bought 200 more milliliters of water than Pete.

Solve. Remember to follow PEMDAS. First, solve for the multiplications within the parenthesis:
((2 * 10) + (4 * 12))/(10 * 12)
((20) + (48))/(120)
Next, Add 20 with 48:
(20 + 48)/120 = (68)/120
Then, divide:
68/120 = 17/30
B) 17/30 is your answer.

can someone please help me.
Answer:
Angle NKO and Angle OKL are adjacent and complementary
Step-by-step explanation:
Adjacent - yes - they have the common vertex K and the common side KO.
Vertical - no - vertical angles are created by two intersecting lines, and angles NKO and OKL are not.
Complementary - yes - since it's given to us that JL and MN are perpendicular, that means that they intersect at 90 degree angles. This means that angles NKO and OKL add up to 90 degrees, and because complementary angles are angles that add up to 90 degrees, NKO and OKL are complementary.
Supplementary - no - supplementary angles are angles that add up to 180 degrees, and since NKO and OKL add up to 90 degrees, they can't be supplementary.
Linear Pair - no - a linear pair is a pair of angles that are adjacent and supplementary. Angles NKO and OKL are adjacent, but since they're not supplementary they can't be a linear pair.

Answer:
[tex]\frac{17}{100}[/tex]
Step-by-step explanation:
A percentage is basically another way of writing a fraction.
If we have a percentage, x%, then it's fraction will be [tex]\frac{x}{100}[/tex].
Since 17 is the percentage here, the fraction is [tex]\frac{17}{100}[/tex].

How far have I travelled if I biked at 10mph for hhrs, I walked at 3mph for twice as long as I biked, and ran at 10mph for one quarter as long as I walked? Translate into expression, I will award brainiest!
Answer:
Total distance traveled= 21h miles
Step-by-step explanation:
You biked at 10 mph for h hours
Speed= 10 mpg
Time = h hours
Distance covered= speed*time
Distance covered= 10h miles
walked at 3mph for twice as long as I biked,
Speed= 3 mph
Time= twice as long as biked
Time= 2(h) hours
Distance= 2h*3
Distance= 6h miles
ran at 10mph for one quarter as long as I walked
Speed= 10 mph
Time= 1/4 of(2h)
Time= 1/2h hours
Distance= 1/2h*10
Distance= 5h miles
Total distance traveled
= 10h miles +6h miles+ 5h miles
Total distance traveled= 21h miles

Based on the similar triangles shown below, Theodore claims that ∆TUV is transformed to ∆WXY with a scale factor of 32. Is Theodore correct? Yes, the triangles are similar with a scale factor of 32. No, the triangles are similar with a scale factor of 21. No, the triangles are similar with a scale factor of 23. No, the triangles are similar with a scale factor of 43.
Answer:
No, the triangles are similar with a scale factor of ⅔
Step-by-step explanation:
Given that ∆TUV was transformed to ∆WXY, it means the original lengths of ∆TUV were multiplied by a scale factor that reduced the lengths of ∆TUV to get the lengths of ∆WXY.
AA scale factor of ³/2 will increase the lengths rather than reduce it.
Therefore, the scale factor that was used was ⅔.
Thus, ⅔ of UT will give you the size of XW. Check it out below:
UT = 12, therefore, ⅔*12 = 8.

Suppose that the functions and are defined as follows.
Answer: (q°r)(4) = 30
(r°q)(4) = 36
Step-by-step explanation:
First, when we have two functions f(x) and g(x), we have that:
(g°f)(x) = g(f(x))
So we are actually evaluating one function with other function.
Now, solving the problem:
q(x) = 2x - 2
r(x) = x^2
we have:
(q°r)(x) = q(r(x)) = 2*r(x) - 2 = 2*(x^2) - 2
(r°q)(x) = r(q(x)) = q(x)^2 = (2*x - 2)^2
Then:
(q°r)(4) = q(r(4)) = 2*r(4) - 2 = 2*(4^2) - 2 = 2*16 - 2 = 32 - 2 = 30.
(r°q)(4) = r(q(4)) = q(4)^2 = (2*4 - 2)^2 = 6^2 = 36.
A study of bone density on 5 random women at a hospital produced the following results.

Step 1: Calculate the correlation coefficient, r. Round your answer to six decimal places.
Step 2: Determine if r is statistically significant at the 0.01 level.
Step 3: Calculate the coefficient of determination, r2. Round your answer to three decimal places.
Answer:
- 0.9503 ; r is not statistically significant ; 0.9031
Step-by-step explanation:
Given the following :
Age (X) :
37
41
57
65
73
Bone density (Y)
355
345
340
315
310
Using the pearson R value calculator :
The r value of the data % - 0.9503.
This value depicts a very strong negative correlation between age and density of bone.
Using the pearson R calculator to obtain the P- value, the P value obtained is .01332 and hence the r is not significant at P < 0.01.
The Coefficient of determination R^2 can be obtained by getting the square value of R
R^2 = - 0.9503^2
R^2 = 0.90307009
R^2 = 0.9031

10. Examine the following solution to a linear equation. Do you see a mistake? Identify the first line of the solution that is incorrect (if any). Original Equation: 30x = 23(1 + 3) + 12x + 22
A. no mistakes
B. step 5
C. step 3
D. step 6
E. step 1
F. step 4
Answer:
x = 19/3
Step-by-step explanation:
Solve for x:
30 x = 12 x + 22 + 23 (1 + 3)
Hint: | Evaluate 1 + 3.
1 + 3 = 4:
30 x = 12 x + 22 + 4 23
Hint: | Multiply 23 and 4 together.
23×4 = 92:
30 x = 12 x + 22 + 92
Hint: | Group like terms in 12 x + 22 + 92.
Grouping like terms, 12 x + 22 + 92 = 12 x + (92 + 22):
30 x = 12 x + (92 + 22)
Hint: | Evaluate 92 + 22.
92 + 22 = 114:
30 x = 12 x + 114
Hint: | Move terms with x to the left hand side.
Subtract 12 x from both sides:
30 x - 12 x = (12 x - 12 x) + 114
Hint: | Combine like terms in 30 x - 12 x.
30 x - 12 x = 18 x:
18 x = (12 x - 12 x) + 114
Hint: | Look for the difference of two identical terms.
12 x - 12 x = 0:
18 x = 114
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 18 x = 114 by 18:
(18 x)/18 = 114/18
Hint: | Any nonzero number divided by itself is one.
18/18 = 1:
x = 114/18
Hint: | Reduce 114/18 to lowest terms. Start by finding the GCD of 114 and 18.
The gcd of 114 and 18 is 6, so 114/18 = (6×19)/(6×3) = 6/6×19/3 = 19/3:
Answer: x = 19/3
H varies directly as L. H=18 when L=60, determine H when L=20
Answer:
6
Step-by-step explanation:
H is proportionate to L, meaning that they can be represented as a ratio, [tex]\frac{h}{l}[/tex].
[tex]\frac{18}{60}[/tex]
If we know that L in the same ratio is 20, we can set these ratio's equal to each other to find H.
[tex]\frac{18}{60} = \frac{x}{20}[/tex].
To find x, we can cross multiply.
[tex]20\cdot18=360\\\\360\div60=6[/tex]
So [tex]x=6[/tex], meaning that when [tex]L=20[/tex], [tex]H=6[/tex].
Hope this helped!
Answer:
H varies directly as L.
H=KL.
18=K60.
K=18/60=0.3.
H=0.3L
when H=?,L=20. then.
H=0.3×20=6.
Solve: 16x2 − 81 = 0
16 x 2 - 81
32-81
= -49
Answer:
x =±9/4
Step-by-step explanation:
16x^2 − 81 = 0
Add 81 to each side
16x^2 − 81 +81 = 81
16 x^2 =18
Divide by 16
x^2 =81/16
Take the square root of each side
sqrt(x^2) = sqrt(81/16)
x =±9/4
On a number line, suppose point E coordinate of -2, and EG=12. what are the possible coordinates of point G?
Answer:
-14 or 10.
Step-by-step explanation:
It is given that, on a number line, suppose point E coordinate of -2, and EG=12.
We need to find the possible coordinates of point G.
Since EG=12 it means point distance between point E and G is 12 units, therefore point G must be on 12 units left or write from point E.
If point G is 12 units left of E, then
G=-2-12=-14
If point G is 12 units right of E, then
G=-2+12=10
Therefore, the possible coordinates of point G are -14 or 10.
Jaime Bailey is chair of a department at a college. Jaime has a budget in which
1.4 of the money is for photocopying, 2/5 of the money is for computer-related expenses, and the rest of the money is for student tutors in the foreign languages lab. What fraction of Jaime's budget is for student tutors?
Answer:
Step-by-step explanation:
7/20
Represent the total budget amount by b.
Then from this b, subtract b/4 and then from the result subtract 2/5:
b - b/4 = (3/4)b; now from this (3/4)b subtract (2/5)b:
Converting these proper fractions to decimal fractions, we get:
0.75b - 0.40b = 0.35b
This tells us that 35/100, or 7/20, of Jaime's budget is for tutors.

[tex](2x-1)(x+5)=2x^2+9x-5=0[/tex].
The quadratic equation has a general form of
[tex]ax^2+bx+c=0[/tex].
So your "b" is 9.
Hope this helps.
Answer: Answer is in the steps
Step-by-step explanation:
(2x-1)(x+5) = 0 First expand the left side by apply the distributive property twice.
(2x -1)(x+5) =0
x(2x -1) = 2x^2 -1x
5(2x -1) = 10x -5
Now rewrite them all together
2x^2 - 1x +10x -5 = 0 combine like terms on the left side.
[tex]2x^{2}[/tex] + 9x -5 = 0 a is the first leading coefficient,b is the second leading coefficient, and c is the constant.
So in this case, the value of b is 9.
