You are building a doghouse for Fido, your loyal poodle. The blueprint of the doghouse uses a scale of 1 : 14. The floor of the doghouse measures 2" x 2.5" on the blueprint.
Answer:
28" x 35"
Step-by-step explanation:
Based on the ratio we see that for every 1 inch in the blueprint there are a total of 14 inches in the real-life model of the doghouse. Therefore, in order to find the actual dimensions of the real-life doghouse we simply need to multiply the individual length and width dimensions of the blueprint by 14. Since the real-life model is 14 times bigger according to the ratio.
2 * 14 = 28
2.5 * 14 = 35
Finally, we can see that the real-life doghouse has a the following dimensions 28" x 35"
The length of one diagonal of a rhombus is 8 cm. The area of the rhombus is 72 cm2. What is the length of the other diagonal of the rhombus?
Answer:
18 cm
Step-by-step explanation:
From the question above,
Area of a rhombus
A = d₁d₂/2.................. Equation 1
Where A = area of the rhombus, d₁ = length of one diagonal, d₂ = length of the other diagonal
make d₂ the subject of the equation
d₂ = 2A/d₁............... equation 2
Given: A = 72 cm², d₁ = 8 cm
Substitute these values into equation 2
d₂ = (2×72)/8
d₂ = 144/8
d₂ = 18 cm.

Near the equator, the Earth rotates approximately 3 4 kilometers every 3 2 seconds. What is the speed of Earth's rotation near the equator?
Answer:
Speed = 1.0625 km / sec
Step-by-step explanation:
Distance = 34 kilometers
Time = 32 seconds
Speed = ?
The relationship between these quantities is given as;
Speed = Distance / Time
Inserting the values;
Speed = 34 km / 32 sec
Speed = 1.0625 km / sec
Solve for the unknown values.
Answer:
x=85
y=45
Step-by-step explanation:
using the sum of a straight angle:
x+95=180
x=85
then we can use the sum of the inner angles of a triangle:
50+85+y=180
y=45
What is the side length of the smallest square plate on which a 30 cm chopstick can fit along a diagonal without any overhang? The approximate side length of the square plate is black cm.
Answer: 21.21 cm
Step-by-step explanation:
Given
length of diagonal on the square is 30 cm
Suppose a is the side length of the square
and length of diagonal is given as [tex]a\sqrt{2}\ units[/tex]
So,
[tex]\Rightarrow a\sqrt{2}=30\\\\\Rightarrow a=\frac{30}{\sqrt{2}}=21.21\ cm[/tex]
Thus, the side length of the square is 21.21 cm
Write the expression as a power of 3

Why does sin30° equal 1/2?
Step-by-step explanation:
it's easy to prove in any right triangle with a 30° angle, the side opposite to that angle is half the hypotenuse. CA (1/2)BC, CA/BC=1/2
Step-by-step explanation:
Take an equilateral triangle of side.
Bisec it through a vertex and the midpoint of the opposite side.
You now have two right-angled triangles with angels 30° , 60°, 90° with the edge opposite the 30° of length 1/2 and hypotenuse 1. So
sin (30°) = 1/2/1= 1/2.
Answer: The right angled triangle you describe has angels of 45 degrees, not 30 degrees.
What you proved is sin 45 = 1\2 , which is correct.

In the inequality 10x + 18 <_238 x represents the number of days Matt will be able to work during the summer. Which phrase MOST accurately describes that number of days?
A. exactly 22 days
B. more than 22 days
C. at most 22 days
D. less than 22 days
25 PTS!!
Answer:(c)
Step-by-step explanation:
Given
Inequality is [tex]10x+18\leq 238[/tex]
Subtract [tex]18[/tex] from both side of the inequality
[tex]\Rightarrow 10x+18-18\leq 238-18\\\Rightarrow 10x\leq 220[/tex]
divide both sides by 10
[tex]\Rightarrow \frac{10x}{10}\leq \frac{220}{10}\\\Rightarrow x\leq 22[/tex]
Therefore, maximum value of x can be 22 i.e. at most 22 days

Answer:
2( 2x -3)(x- 5)
Step-by-step explanation:
step 1 . factor 2 out ( because when you multiply the 2 again with the equation it will give you the main equation)
2 ( 2x^2 - 13x + 15 )
step 2 . factor now by regrouping
2( 2x- 3 )( x - 5)
