Answer:
30 inches squared
Step-by-step explanation:
The formula for a RIGHT triangle is:
[tex]A= \frac{ab}{2}[/tex]
We are given..
a = 5 inchesb = 1 foot = 12 inchesTherefore...
[tex]A = \frac{5(12)}{2}[/tex]
[tex]A=\frac{60}{2}[/tex]
[tex]A = 30[/tex]
Devonte opens a savings account by making a deposit of $249.45. Every week, he deposits another $31.75 in the account. Which expression shows the amount of money that will be in the account w weeks after the account is opened? 249.45 w + 31.75 249.45 w minus 31.75 249.45 + 31.75 w 249.45 minus 31.75 w
Answer:
249.45 + 31.75w
Step-by-step explanation:
Opening deposit = $249.45
Weekly deposit made into account = $31. 75
Amount of money which will be in account w weeks after opening :
Opening deposit + (weekly deposit * number of weeks)
Amount after w weeks :
$249.45 + (31.75 * w)
$249.45 + 31.75w

what is the coefficient in -x+9
Answer:
-1
Step-by-step explanation:
The coefficient is the number directly next to a given variable (typically 1 if there is no given number).
In this case, note the variable: -x
As stated above, the number is 1 if there is no number given. However, note that there is a negative sign, therefore, your coefficient is -1
-1 is your answer.

Which equation represents a line that is parallel to the line represented by
4x + y = 7 and passes through the point (1, 8)?
Answer:
y = -4x + 12
Step-by-step explanation:
For a line to be parallel, it needs to have the same slope.
Point intercept form: y - y₁ = m (x - x₁)
Where y and x are just kept as y and x, y₁ and x₁ are the parts of a coordinate, and m = slope.
So, in order for the line to be parallel, it needs to have the same slope as the first equation. The slope of the line (which is the "m" in y = mx + b) is..
4x + y = 7
y = -4x + 7
So, m, or the slope, is -4.
Plug this, along with the coordinate the problem gives you into point-intercept form.
y - y₁ = m (x - x₁)
y - 8 = -4 (x - 1)
Simplify.
y - 8 = -4x + 4
Add 8 to both sides.
y = -4x + 12

The length of the base of an isosceles triangle is x. The length of a leg is 2x - 3. The perimeter of the triangle is 34. Find x.
Answer:
x=8
Step-by-step explanation:
If the triangle is isosceles, it means that 2 of its sides are equal in length, therefore its perimeter is equal to
[tex](2x - 3) + (2x - 3) + (x)[/tex]
Adding similar terms, and recalling that the perimeter is equal to 34, we get
[tex]5x - 6 = 34 \\ 5x = 40 \\ x = 8[/tex]

Answer:
y = 6/7x - 37/7
Step-by-step explanation:
m = 6/7
(5, -1)
y - y1 = m(x - x1)
y + 1 = 6/7(x - 5)
y + 1 = 6/7x - 30/7
y = 6/7x - 37/7
Answer:
Step-by-step explanation:
Start by the point-slope form and given slope = 6/7 and point (5, -1)
(y-(-1)) / (x-5) = 6/7
7(y+1) = 6(x-5)
7y = 6x - 37
y = 6x/7 - 5 2/7
which is the answer in slope-intercept form

An oblique candle with a volume of 270 cubic centimeters is 18 centimeters tall. The width of the triangular candle base is 5 centimeters, and the width of the slanted candle is 7 centimeters. An oblique triangular prism has a volume of 270 cubic centimeters. The vertical height is 18 centimeters. The width of the triangular bases is 6 centimeters, and the width of the slanted prism is 7 centimeters. What dimensions of the box are required to fit the candle? 5 cm by 6 cm by 18 cm 7 cm by 6 cm by 18 cm 5 cm by 3 cm by 18 cm 7 cm by 3 cm by 18 cm
Answer:
7 cm by 6 cm by 18 cm
Step-by-step explanation:
Given :
Volume of candle = 270cm³
Height = 18cm
Triangular base = 5cm
Width of candle = 7cm
Volume = Area of base * height
270cm³ = Area of base * 18
Area of base = 270cm³ / 18cm
Area of base = 15 cm²
Using this to find the height of triangular prism :
Area = 1/2 * base * height
15cm² = 1/2 * 5 * height
15cm² = 2.5 *. Height
Height = 6 cm
Hence, the dimension of triangular prism is : 7cm by 6cm by 18cm
Answer:
7 cm by 6 cm by 18 cm

Find the value of x.
Answer:
x= 37.5°
Step-by-step explanation:
∠CBD
= 180° -75° (adj. ∠s on a str. line)
= 105°
∠BCD= ∠BDC (base ∠s of isos. △BCD)
∠BCD= x
∠BCD +∠BDC +∠CBD= 180° (∠ sum of △BCD)
x +x +105°= 180°
2x= 180° -105°
2x= 75°
x= 37.5°
Alternative working:
∠BDA= (180° -75°) ÷2 (base ∠s of isos. △ABD)
∠BDA= 52.5°
∠BDA +∠BDC= 90°
52.5° +x= 90°
x= 90° -52.5°
x= 37.5°
how to solve -6x+5y=16 and x=5-3y using subsituation
Answer:
you already have x solved for so you plug 5-3y into the x in -6x and you get -6(5-3y)+5y=16
-30+18y+5y=16
-30+23y=16
23y=46
y=2
x=5-3(2)
x=5-6

What two numbers have a sum of 215 and a difference of 137
Answer:
see below
Step-by-step explanation:
let x = big number
let you = small number
x + y = 215-------> (1)
x - y = 137 ------>(2)
(1)
x = 215 - y ----->(1)
substitute 1 into 2
215 - y -y = 137
-2 y = 78
y = 39
substitute y = 39 into (1)
x = 215 - (39)
x = 176
thus the numbers are 176 & 39

Based on this information, which of the following statements is true?
A. The volume of the larger cylinder is 2 times the volume of the smaller cylinder.
B. The volume of the larger cylinder is 4 times the volume of the smaller cylinder.
C. The volume of the larger cylinder is 8 times the volume of the smaller cylinder.
D. The volume of the larger cylinder is 6 times the volume of the smaller cylinder.
The true statement is The volume of the larger cylinder is 8 times the volume of the smaller cylinder.
The correct option is (C)
What is Volume of cylinder?The volume of cylinder is, V= πr²h.
Volume of large cylinder,
= πr²h
= πd²(2h)
= 2hπd²
Volume of large cylinder,
= πr²h
= π(d/2)²(h)
= πd²h/4
= 2πd²h/8
Hence, The volume of the larger cylinder is 8 times the volume of the smaller cylinder.

[tex]\huge\boxed{1) 2n^2-9n}[/tex]
[tex]\huge\boxed{2) 6c\³ + 4c\²}[/tex]
Step-by-step explanation:
Part 1:
= n(n-4)-n(5-n)
By distributive property
= n² - 4n - 5n + n²
= 2n² - 4n - 5n
= 2n² - 9n
Part 2:
= 4c(3c-c²)-2c²(4-5c)
Distributing brackets
= 12c² - 4c³ - 8c² + 10c³
Combining like terms
= 12c² - 8c² - 4c³ + 10c³
= 4c² + 6c³
= 6c³ + 4c²
