0.25
Step-by-step explanation:
1.75/7 would equaln0.25, use your calculator if you have one
The decimal 1.75 when divided by the number 7 gives the decimal 0.25.
In mathematics, a decimal is a base-10 numeral system applied to characterize real numbers. It's known as "decimal" because it uses ten dissimilar symbols, videlicet the digits 0 through 9, to portray all achievable values. The decimal system is the most generally used numeral system in day-to-day life.
The decimal system works on a positional memorandum principle, where each digit's position determines its value within the number.
The decimal 1.75 can be written as a fraction as follows:
[tex]1.75 = \dfrac{175}{100}[/tex]
[tex]= \dfrac{7}{4}[/tex]
To divide 1.75 by 7, let's divide [tex]\dfrac{7}{4}[/tex] by 7.
[tex]\dfrac{7}{4} \div 7\\= \dfrac{7}{4} \times \dfrac{1}{7}\\= \dfrac{1}{4} \times 1\\= \dfrac{1}{4}\\= 0.25[/tex]
Thus, 0.25 is 1.75 divided by 7.

A year ago, Ray's puppy weighed 8 pounds. Now his puppy weighs 25 pounds
more. How much does Ray's puppy weigh now? Explain using pictures,
numbers, or words.
Answer:
Puppy's current weight = 33 pounds.
Step-by-step explanation:
The weight of Ray's puppy 1 year ago = 8 pounds
Now, his puppy weighs 25 pounds more.All we need is to add the 8 pounds to 25 to determine the current weight.
i.e.
current weight = 8 + 25
= 33 pounds
Therefore, puppy's current weight = 33 pounds.

Answer:
These are similar triangles.
By changing the length of the base of the corresponding triangle, the 3 interior angles of this triangle remain equal to the original
Therefore, if these triangles are similar, their corresponding sides must give equal ratios to each other:
This means that BF/FE = BC/CD=FC/ED
The total length of line segment BD=BC+CD; BC=6, CD=42; BD=6+42, BD=48
BE=BF+FE; BE=9+?
if BF/FE=BC/CD then 9/BE=6/42; 6/42=3/21 or 1/7. 9/BE=1/7; 1/7=9/BE
1x9=9, 7x9=63
63=BE
Step-by-step explanation:
Answer:BE is equal to 72.
Step-by-step explanation: They are similar triangles. We know CD and BC. So we can find the comparison between the two. And we see that BC x 7 = CD. So the same will be said for BF and FE. We have BF is equal to 9. So 9 x 7 = 63. However, now we need to add the two together in order to get BE. Because BF + FE = BE. So 9 + 63 = 72
Find the area. Simplify your answer.
X+8
х
Answer:
x²+8x
Step-by-step explanation:
area of rectangle
l×w
(x+8)×x
x²+8x
The area of the rectangle is [tex]X^2 + 8X[/tex].
To find the area of a rectangle, we multiply its length by its width.
In this case, the length is (X + 8)
and the width is X.
so, we have,
Area = Length * Width
Area = (X + 8) * X
To simplify the expression, we need to distribute the X through the parentheses:
Area = X * X + 8 * X
Area = [tex]X^2 + 8X[/tex]
So, the area of the rectangle is [tex]X^2 + 8X[/tex].

A publisher makes books for a number of distributors. For one book, the charge to the distributor is represented by a fixed cost of $3000 plus $16 per book. a) How much would 600 books cost b) what is the cost per book if 600 are ordered c) what is the cost per book if 1000 are ordered
Answer:
a. $12,600
b. $21
c. $19
Step-by-step explanation:
a) The cost is $3000 plus $16 per book
For 600 books, we have
3000 + 16(600)
= 3000 + 9600 = $12,600
b) Cost per book will be;
12,690/600 = $21
c) for 1000
= 3000 + 16(1000)
= 3000 + 16,000 = 19,000
cost per book is 19,000/1000 = $19

In ΔWXY, the measure of ∠Y=90°, XW = 89, WY = 80, and YX = 39. What ratio represents the cosine of ∠X?
Answer:
It's 39/89
Step-by-step explanation:
cos X = adjacent/ hypotenuse = 39/89
[tex]\frac{39}{89}[/tex] represents cosine of ∠X.
What is cosine?
'In a right-triangle, cos is defined as the ratio of the length of the adjacent side to that of the longest side which is the hypotenuse.'
According to the given problem,
In the right angle triangle ΔWXY,
Hypotenuse = XW = 89
Perpendicular = WY = 80
Base = YX = 39
We know,
cos∅ = [tex]\frac{Base}{Hypotenuse}[/tex]
⇒ cosX = [tex]\frac{39}{89}[/tex]
Hence, we can conclude that the ratio [tex]\frac{39}{89}[/tex] represents the cosine of ∠X

Alyssa used a can of paint that was 5/6 full to touch paint her house. When she was done, the bucket was 11/30 full. What fraction of the can did she use?
Answer:
7 / 15
Step-by-step explanation:
Fraction before painting = 5/6
Fraction left after painting = 11/30
Fracrion used = difference of the fraction before painting and fraction left after painting
Fraction used = 5/6 - 11/30
Lowest common factor of 6 and 30 = 30
5/6 - 11/30 = (25 - 11) / 30 = 14/ 30
Fraction used = 14/30 = 7/15

Answer:
Option C
Step-by-step explanation:
Since, measure of all sides of the triangle has been given in the picture,
By applying cosine rule in the given triangle,
AC² = AB² + BC² - 2(AB)(BC)cos(B)
11² = 16² + 16² - 2(16)(16)cos(B)
121 = 256 + 256 - 512.cos(B)
121 - 512 = - 512.cos(B)
cos(B) = [tex]\frac{391}{512}[/tex] = 0.763672
B = [tex]cos^{-1}(0.763672)[/tex]
B = 40.2°
Therefore, measure of angle B is 40.2°.

Answer:
The composite area is a total of 62 square inches.
Step-by-step explanation:
You're given three rectangles of different width and height. To find the correct answer, you need to find the sum of each rectangles' area.
first though we need to find the height of the middle rectangle. We are told the total height and the other two rectangles' heights, so we just need to subtract the others' heights from the total:
10 - (4 + 1.5)
10 - 5.5
= 4.5
So the middle rectangle is 4x4.5 inches, giving it an area of 18 square inches
The top one is 8x4 inches for a total of 32 square inches.
And the bottom one is 1.5x8 inches, for a total 12 square inches.
If we add them all up, that's 18 + 32 + 12 square inches, or 62 square inches.

A piece of paper has a rectangle ABCD in which AB= 10 cm and BC = 22 cm , it was folded to form a right circular cylinder such that AB is cincident to DC . Find the volume of the resulted cylinder
Answer: [tex]385cm^{2}[/tex]
Step-by-step explanation:
given data:
AB= 10 cm.
BC = 22 cm.
volume of a cylinder V = [tex]\pi r^{2} h[/tex]
h = 10.
solution
base of the circumference = 22cm
circumference of a circle = [tex]2\pi r[/tex]
r = radius is unknown.
[tex]2\pi r = 22[/tex] .........................eq1
where [tex]\pi = \frac{22}{7}[/tex] insert this into eq1.
[tex]2* \frac{22}{7}* r = 22[/tex]
[tex]\frac{44}{7} r = 22[/tex]
[tex]r = \frac{22}{\frac{44}{7} }[/tex]
[tex]r= 3.5cm[/tex]
next we solve for the volume of the cylinder.
recall [tex]V = \pi r^{2} h[/tex]
h = 10cm
r = 3.5cm
[tex]V = \frac{22}{7} * (3.5)^{2} *10[/tex]
[tex]V = 385cm^{2}[/tex]

Which equation matches the graph?
In the xy graph, the range of the x axis is zero to four by increment of one. The range of y axis is zero to eight by increment of one. On both axes every alternate tick mark is labeled. On the graph, there is a line passing through the points (2, 2) and (0, 8).
Answer:
[tex]y = -3x +8[/tex]
Step-by-step explanation:
The graph diagram is not given; however, the equation can be solved from the given points
(2,2) and (0,8)
This is represented as:
[tex](x_1,y_1) = (2,2)[/tex]
[tex](x_2,y_2) = (0,8)[/tex]
Calculate slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{8 - 2}{0 - 2}[/tex]
[tex]m = \frac{6}{- 2}[/tex]
[tex]m =-3[/tex]
The equation is calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 2 = -3(x - 2)[/tex]
[tex]y - 2 = -3x + 6[/tex]
Add 2 to both sides
[tex]y - 2 +2= -3x + 6+2[/tex]
[tex]y = -3x + 6+2[/tex]
[tex]y = -3x +8[/tex]

Simplify the expression. -2.5f + 0.4f - 14 - 3?
Answer:
-2.1f-17
Step-by-step explanation:
combine like terms
Answer:
-2.1f-17
Step-by-step explanation:
1. Combine like terms
Like terms are those that either have the same variable, degree, or no variable at all.
Here, -2.5f and 0.4f and -14 and -3 are like terms. -2.5f and 0.4f are like terms because they both have f beside them. The reason -14 and -3 are like terms is because they both stand alone with no variables.
Combining like terms means to either add or subtract them from each other depending on their signs.
Just think of them as two separate problems for now.
-2.5f + 0.4f = ?
add these two together to get -2.1f
-14-3
Subtract these to get -17.
2. Put the expression back together: -2.1f-17

Step-by-step explanation:
We do not count the counselors or the principal because they are not students, so we do 83 - 3 = 80, now it is just simple division, for every student there is a parent, so we divide 80 in half, 80 / 2 = 40 students :D
Her house is at (−4, 10). Her school is at (−4, 3). The community center is at (2, 3). The grocery store is at (−4, −6). Part A: Use absolute values to calculate the distance in units from Nina's house to her school
Answer:
7 units
Step-by-step explanation:
Given that :
house is at (−4, 10). Her school is at (−4, 3)
House location = (-4, 10)
School location = (-4, 3)
Distance from house to school (d) :
Distance between two points :
x = sqrt[(x2 - x1)^2 + (y2 - y1)^2]
x1 = - 4 ; y1 = 10 ; x2 = - 4 ; y2 = 3
d = sqrt[(-4 - (-4))^2 + (3 - 10)^2]
d = sqrt[(-4 + 4)^2 + (-7)^2]
d = sqrt(0 + (-7)^2)
d = sqrt(49)
d = 7 units
