Given:
There are given the statement:
25 days to 5 weeks.
Explanation:
To find the ratio, first, we need to convert the value of days into the week.
So,
To convert days into the week, we need to divide by 7.
So,
[tex]\frac{25}{7}week[/tex]Now,
The ratio as a fraction is:
[tex]\frac{25}{\frac{7}{5}}=\frac{25}{7\times5}[/tex]Then,
[tex]\begin{gathered} \frac{25}{\frac{7}{5}}=\frac{25}{7\times5} \\ =\frac{5}{7} \end{gathered}[/tex]Final answer:

if a pound of almonds cost eight dollars how many ounces can be bought for $3.80
Proportions
A pound of almonds is said to cost 8 dollars.
But one pound is equivalent to 16 ounces, therefore:
16 ounces cost 8 dollars
Dividing by 8 we get that
2 ounces of almonds cost 1 dollar
Thus, for $3.80 we can buy 2*3.80 = 7.60 ounces of almonds

A standard die is rolled. Find the probability that the number rolled is less than 3. Express your answer as a fraction
Once a die has the numbers 1,2,3,4,5 and 6, it means the numbers that are less than 3 are just the numbers 1 and 2. Now the probability can be built as follows:
As we can see above, once there are just two possibilities of numbers that are less than 3, the probability that the number rolled is less than 3 is equal to 2/6.
A chemistry student needs 80.0 mL of ethanolamine for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers thatthe density of ethanolamine is 1.02 g.cm. Calculate the mass of ethanolamine the student should welgh out.Be sure your answer has the correct number of significant digits.
STEP 1: Identify and Set Up
We are given a question that requires us to find mass when given volume and density.
It is common knowledge that these parameters are related by the formulae:
[tex]\begin{gathered} \text{density = }\frac{\text{mass}}{\text{volume}} \\ \text{This gives mass = volume }\times\text{ density} \end{gathered}[/tex]We use this relation to find mass
STEP 2: Execute
Density = 1.02 g/cc
Volume = 80ml = 80 cc
Mass is therefore:
[tex]\text{mass = 1.02}\times80=81.6g[/tex]Mass = 81.6g

The measure of angle m∠A will be 70°,for the parallelogram ABCD
Parallelogram and its Properties:
Parallelogram is a special kind of quadrilateral, in which opposite sides are equal and parallel to each other.
Properties:
1. Opposite sides are parallel to each other.
2. Length of opposite sides are equal.
3.Diagonally opposite angles are equal.
4. Diagonals bisects each other.
5. Sum of any two adjacent angle is 180°
From figure,
ABCD is a parallelogram
m∠A = 2x + 50
m∠ C = 3x + 40
In a parallelogram ABCD we know opposite angles are equal to each other,
m∠A = m∠C
2x + 50 = 3x + 40
3x - 2x = 50 - 40
x = 10
Hence,
m∠A = 2x + 50
put the value of x we get,
m∠A = 2 * 10 + 50
= 20 + 50
= 70°
m∠A = 70°

in 2 years steve wants to buy a bicycle that 800.00. if he opens a savings account that earns 3 % interest compounded monthly how much will he have to despoit as principal to have enough money in 2 years to buy the bike
Answer
393.55
Explanation
The amount that results after an amount P is invested at compound interest at rate r% and time period t is given as
A = P (1 + r)ᵗ
For this question,
A = 800
r = 3% = 0.03
t = 2 (12) = 24 (Since the interest is compounded monthly, over 2 years)
P = ?
800 = P (1 + 0.03)²⁴
800 = P (1.03)²⁴
800 = P (2.0328)
2.0328P = 800
Divide both sides by 2.0328
(2.0328P/2.0328) = (800/2.0328)
P = 393.55

Luke opened a savings account 3 years ago. the account earns 6%interest compounded quarterly if the current balance is 300.00 how much did he deposit initially
Answer
This is similar to the first one too.
A = P (1 + r)ᵗ
For this question,
A = 300
r = 6% = 0.06
t = 3 (4) = 12 (Since the interest is compounded quarterly, over 3 years; there are 4 quarters per year)
300 = P (1 + 0.06)¹²
300 = P (1.06)¹²
300 = P (2.0122)
2.0122P = 300
Divide both sides by 2.0122
(2.0122P/2.0122) = (300/2.0122)
P = 149.09

What does congruence of triangle mean?Triangles are said to be congruent if the three angles and three sides of a triangle are equal to the corresponding angles and sides of another triangle.
To be congruent, two triangles must have the same size and shape. The two triangles under consideration must overlap. If you rotate, flip, and/or move the triangle, its position and appearance will look different. In this case, we need to identify the six parts of one triangle and the corresponding parts of the other triangle.
For the triangles ΔAXD and ΔCXD
AD = DC ( congruent sides)
∠XDA = ∠XDC = 90° ( XD is perpendicular to AC)
XD is the common side.
This proves that triangles ΔAXD and ΔCXD are congruent
So it concludes, that XD = XC

$75.00 is shared among 3 people in the ratio 2:4:9 how much is the largest share?
The ratio is 2:4:9, so we can consider the total parts we are dividing the total as 2+4+9 = 15.
Then, the first person receives 2/15, the second receives 4/15 and the third receives 9/15.
As the total is 75, we can calculate each part as:

If the radius of circle M is 7, and LK = 18, find JK
Answer:
JK = 24
Explanation:
If the radius of circle M is 7, we can say that MJ = 7 and ML = 7
So, the length of MK will be equal to:
MK = ML + LK
MK = 7 + 18
MK = 25
Now, we have a right triangle JMK, and we know the length of one leg MJ = 7 and the length of the hypotenuse MK = 25. Using the Pythagorean theorem, we can find the length of the other side JK, so
