Answer:
13, 14, 15
Step-by-step explanation:
13 + 14 + 15 = 42
Better explanation:
n + (n+1) + (n+2) = 42
42 - 2 - 1 = 39
n + n + n = 39
3n = 39 divide by 3 to isolate n
n = 13
So it starts with 13 and goes up from there.
f(x)=-x^2-10x
Find f(-5)
Answer:
25
Step-by-step explanation:
f(x)=-x^2-10x
Let x = -5
f(-5)=-(-5)^2-10(-5)
= -25+50
=25

It take 5 minutes to help a restock an area. How much areas can you restock in 50 minutes?
Answer:
10 areas
Step-by-step explanation:
5 minutes = 1 area
→ Divide the 50 by the 5
50 ÷ 5 = 10
→ Multiply this by the area
10 × 1 = 10
Point B is on line segment AC. Given AB=4x-6, AC=2x+10, and BC=4, determine the numerical length of AC
Answer:
AC = 22
Step-by-step explanation:
AB + BC = AC , substitute values
4x - 6 + 4 = 2x + 10 , that is
4x - 2 = 2x + 10 ( subtract 2x from both sides )
2x - 2 = 10 ( add 2 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Then
AC = 2x + 10 = 2(6) + 10 = 12 + 10 = 22

Find the length of "c" to the
nearest tenth using the
Pythagorean Theorem.
Enter
Answer:
10.6
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Where a and b = the legs and c = hypotenuse
We are given two legs and need to find the hypotenuse
Given:
Short leg (a) = 7
Long leg (b) = 8
Hypotenuse = c
Now to find the value of c we simply plug in the values of the variables into the Pythagorean theorem and solve for c
Pythagorean theorem: a² + b² = c²
a = 7, b = 8, c = c
Plug in values
7² + 8² = c²
Now solve for c
Simplify exponents
49 + 64 = c²
Add
113 = c²
Taking the square root of both sides
c = 10.6 ( rounded to the nearest tenth )
Answer:
c = 10.6
Step-by-step explanation:
[tex]h {}^{2} = p {}^{2} + b {}^{2} \\ c {}^{2} = (8) {}^{2} + (7) {}^{2} \\ c = \sqrt{64 + 49} \\ c = \sqrt{113} \\c = 10.6[/tex]

Answer:
25.7
Step-by-step explanation:
PQ=PR-QR
PQ=38.3-12.6
PQ=25.7 cm
Answer: PQ = 25.7 cm
Concept:
Here, we need to know the idea of the segment addition postulate.
The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
Solve:
Given information
PR = 38.3 cm
QR = 12.6 cm
Given expression deducted from the segment addition postulate
PQ = PR - QR
Substitute values into the expression
PQ = (38.3) - (12.6)
Simplify by subtraction
PQ = [tex]\boxed{25.7cm}[/tex]

In a school library, 40% of the books are in Nepali language, 40% of the remaining books are in English and the remaining books are in regional languages. If the number of books in English language is 4800, find the total number of books in the library,
Step-by-step explanation:
Solution,
Let the total number of books be x, then
Books in English language=4800
40% of x=4800
40/100×x=4800
40x/100=4800
40x=4800×100
40x=480000
x=480000/40
x=12000
So the total number of books in the library is 12000.

A rectangle has perimeter 66 cm and length 27 cm. What is its width?
(help pls it’s my hw)
Answer:
Step-by-step explanation:
A rectangle has the perimeter of 66cm, and since a rectangle has 2 lengths and 2 widths, we can tell that 2 widths = 66-27*2 = 12
so 1 width is half of 12 which is 6
3/4x + 4/7y = 5/4x -1...solve for y
Answer:
[tex] \frac{3}{4} x + \frac{4}{7} y = \frac{5}{4} x - 1 \\ \frac{4}{7} y = \frac{5}{4} x - 1 - \frac{3}{4} x \\ \\ \frac{4}{7} y = \frac{5x - 4 - 3x}{4} \\ \frac{4}{7} y = \frac{2x - 4}{4} \\ \\ y = \frac{2x - 4}{4} \div \frac{4}{7} \\ y = \frac{2x - 4}{4} \times \frac{7}{4} \\ \\ y = \frac{14x - 28}{16} \\ \\ y = \frac{14x}{16} - \frac{28}{16} [/tex]

4. Determine both the HCF and LCM of 25 and 200
Answer:
The LCM of 25 and 200 is 200.
Explanation:
Find the prime factorisation of 25
25 = 5 × 5
Find the prime factorisation of 200
200 = 2 × 2 × 2 × 5 × 5
Multiply each factor the greater number of times it occurs in steps 1 or 2 above to find the LCM:
LCM = 2 × 2 × 2 × 5 × 5
LCM = 200
Answer:
the HCF of 25 and 200 is 25 because it divides both of them and is maximum factor of them.
LCM of 25 and 200 is 200 because it can be divided by both 200 and 25

4 The equation 5W + 3 = 4w + 9 is modeled below. w W 1 W W 1 1 W 1 1 W W 1 1 1 What value of w makes this equation true? Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value. MI - SI – PSA- S-
Answer:
w = 6.
Step-by-step explanation:
5w + 3 = 4w + 9
5w - 4w = 9 - 3
w = 6
Then, check your work!
5(6) + 3 = 4(6) + 9
30 + 3 = 24 + 9
33 = 33
So, w = 6 will be the correct answer.
