Suppose that 13 inches of wire costs 52 cents. At the same rate, how much (in cents) will 34 inches of wire cost.
Find price per inch:
0.52 / 13 = 0.04 per inch.
Multiply cost per inch by inches:
0.04 x 34 = 1.36
It will cost $1.36 for 34 inches.

6.5 ft 6 ft- 11 ft N 5 ft What is the surface area? A 258 square feet B 195 square feet C 228 square feet D 330 square feet
Answer:
Step-by-step explanation:
area of base = 5×11 = 55 ft²
area of triangle = ½×5×6 = 15 ft²
area of rectangular face = 6.5×11 = 71.5 ft²
surface area = 55 + 2×15 + 2×71.5 = 228 ft²
What is the equation of the line that passes through (3.-5) and is parallel to 5x - 3y = 15?
Answer:
y = 5/3x - 10
Step-by-step explanation:
[tex]5x - 3y = 15\\-3y = -5x + 15\\y = 5/3x - 5[/tex]
that means the slope of the new line also has to be 5/3 because parallel lines have the same slope.
put it in point-slope form:
y - -5 = 5/3(x - 3)
y + 5 = 5/3x - 5
y = 5/3x - 10

factorise (2t-7)²-(5t-4)²
with working pls
Answer:
33+12t−21t^2
Step-by-step explanation:
(2t-7)²-(5t-4)²
Use binomial theorem (a−b)^2 = a^2−2ab+b^2 to expand (2t-7)².
4t^2−28t+49−(5t-4)²
Use binomial theorem (a−b)^2 = a^2−2ab+b^2 to expand (5t-4)².
4t^2−28t+49−(25t^2−40t+16)
To find the opposite of 25t^2
−40t+16, find the opposite of each term.
4t^2−28t+49−25t^2−40t+16
Combine 4t^2 and −25t^2 to get −21t^2.
−21t^2−28t+49+40t−16
Combine −28t and 40t to get 12t.
−21t^2+12t+49−16
Subtract 16 from 49 to get 33.
−21t^2+12t+33
Swap terms to the left side.
33+12t−21t^2

solve the following
a brick measures
l= 15 cm
b= 8 cm
h= 5 cm
how many bricks will be used to make a wall of length=15 m, breath=10 m and height=8m
Answer:
2000000 bricks
Step-by-step explanation:
The computation of the number of bricks to be used is shown below:
The Volume of brick is
= (15 × 8 × 5)cm^3
= 600 cm^3
And, the Volume of wall is
= (1500 × 1000 × 800)cm^3
= 1200000000 cm^3
Now Bricks needed is
= 1200000000 cm^3 ÷ 600cm^3
= 2000000 bricks

D.
The number is irrational because it is a repeating decimal.
0.81382 is a rational number because it is a terminating decimal.
What is rational number?
A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero, and also whose behavior is known.
What is irrational number?An irrational number is a type of real number which cannot be represented as a simple fraction and also whose behavior is not known.
According to the given question.
We have a number 0.81382
The above number is not repeating but terminating.
Therefore, we can say that the above number is rational because it is a terminating decimal.
Hence, 0.81382 is a rational number because it is a terminating decimal.

if SP =210 profit percent =5% CP = X , find CP
Step-by-step explanation:
Given
SP = 210
profit percent (p%) = 5%
CP = X = ?
We know
Cost price (CP)
[tex] = \frac{sp \: \times 100}{100 + p\%} \\ = \frac{210 \times 100}{100 + 5} \\ = \frac{21000}{105} \\ = 200[/tex]
hope it helps :)❤
Or in another way
Let the cost price be x then
Profit amount
= 5 % of CP
= 5/100 * x
= x / 20
Selling Price (SP)
210 = CP + Profit amount
210 = x + x / 20
210 = ( 20x + x) / 20
210 * 20 = 21x
4200 = 21x
x = 4200 / 21
x = 200
Therefore CP = 200

Answer:
d = 105tan(37°)Step-by-step explanation:
opposite (o) = d
adjacent (a) = 105
Angle A = 90 - 53 = 37°
Therefore,
the correct equation would be
tan(A°) = opposite/adjacent
tan(37°) = d/105
d = 105tan(37°) ✅d = 105 × 0.7535540501
d ≈ 79.12 units
