Enlarge the house using a scale factor of 1 : 2.
Answer:
See picture & explanation below.
Step-by-step explanation:
The scale is 1:2, so everything is doubled in size.
Count the number of squares each segment is in length and multiply it by 2. Then draw all new segments that are twice as long as the original ones to create a house that is twice as large as the original house.
See the picture below.

Ben has a dog that has a mass of 9 kilograms. What is the mass of the dog in grams?
Answer:
9000 grams
Step-by-step explanation:
Keep in mind the conversion 1 kilogram = 1000 grams, as 1 kilo means 1000.
⇒ 1 kilogram = 1000 grams
⇒ Ben's dog = 9 kilogram = x kilograms = 1000x grams
⇒ x = 9
⇒ Ben's dog = 9 kilogram = 1000x grams
= 1000(9) grams
= 9000 grams
Answer:
Your answer is,
9000 grams

PLEASE HELP W BOTH PRECALC QUESTIONS!!!
Answer:
Step-by-step explanation:
Use the formulas supplied in the picture attached. There's nothing to really learn here, it is just a plug-and-chug formula:
[tex]sin(3x)sin(2x)=\frac{1}{2} [cos(3x-2x)-cos(3x+2x)][/tex]
[tex]sin(3x)sin(2x)=\frac{1}{2} [cos(x)-cos(5x)][/tex]
Moving on to the second problem:
[tex]cos(a)sin(b)=\frac{1}{2}[ sin(a+b)-sin(a-b)][/tex]
Therefore:
[tex]2cos(a)sin(b)=sin(a+b)-sin(a-b)[/tex]
Where:
[tex]a+b=5x[/tex]
[tex]a-b=3x[/tex]
Solve for 'a' using the second equation to get:
[tex]a=3x+b[/tex]
Plug this into the first equation to get:
[tex]3x+b+b=5x[/tex]
[tex]3x+2b=5x[/tex]
[tex]2b=2x[/tex]
[tex]b=x[/tex]
Therefore:
[tex]a+x=5x[/tex]
[tex]a=4x[/tex]
Finally:
[tex]sin(a+b)-sin(a-b)=2cos(4x)sin(x)[/tex]
The distance from earth to the moon is about 3.84 times 10^6 meters. what is one fourth of this distance
If the distance from the earth to the moon is about 3.84 x 10⁶.One-fourth of this distance will be 960,000
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, the distance from the earth to the moon is about 3.84 x 10⁶.
One-fourth of this distance is found by dividing the total distance by 4.
We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.
Suppose the one-fourth of this distance will be x,
(1/4)× 3.84 x 10⁶ =x
x=(3.84 x 10⁶)/4
x=960,000
Thus, if the distance from the earth to the moon is about 3.84 x 10⁶. One-fourth of this distance will be 960,000

Find the center and radius of the circle represented by the equation below.
(x + 5)² + (y – 5)² = 225
1
Center:
Radius:
Answer: the center is (-5, 5) and the radius is 15
Step-by-step explanation:
the standard form of a circle is
(x-h)^2 + (y-k)^2 = r ^2 where h is the x coordinate and k is the y coordinate of the center of the circle
(h,k) = the center of the circle
r = radius
therefore,
(x+5)^2 + (y-5)^2 = 225 means that x has to be -5 since subtracting a negative creates a positive and y must be 5 as it is negative in the equation
think of it as making the sum/difference 0 within the parentheses:
(x+5) -5+5 = 0 so x=-5
(y-5) 5-5 = 0 so y =5
so the center of the circle is (-5,5)
the radius is simply 225 square rooted which is 15

find the LCM of denominator 3/8 and 3/4
Answer:
Step-by-step explanation:
Actually, it is 8.
3/8: nothing need be done.
3/4: Multiply top and bottom of the fraction by 2.
3*2 / 4*2 = 6/8
So the lowest common multiple is 8.
The factions become 3/8 and 6/8
Which inequality would result in the shaded solution on the unit circle to the right?
Explanation:
Cosine is positive in quadrants I and IV, but quadrant IV isn't shaded in so we can rule out choice A.
Sine is positive in quadrants I and II. So far it looks like choice B could work. In fact, it's the answer because sin(pi/6) = 1/2 and sin(5pi/6) = 1/2. So if 0 ≤ sin(x) < 1/2, then we'd shade the region between theta = 0 and theta = pi/6; as well as the region from theta = 5pi/6 to theta = pi.
Choice C is ruled out because tangent is positive in quadrants I and III, but quadrant III isn't shaded.
Choice D is ruled out for similar reasoning as choice A. Recall that [tex]\sec(x) = \frac{1}{\cos(x)}[/tex]
Answer:
0 ≤ sin x < 1/2.
Step-by-step explanation:
sin π6 = 1/2
sin 5π/6 = 1/2
sin 0 and sin 180 = 0
The dotted line indicates that the value of the sine is less than 1/2 and the solid line indicates that value is greater or equal to zero.
So the inequality is 0 ≤ sin x < 1/2

Answer:
D = 1120
Step-by-step explanation:
Given:
W = 70T = 4Substitute the values into the equation:
⇒ D = WT²
[tex]\text{D = WT}^{2} \ \text{can also be written as D = (W)(T)(T)}[/tex]
⇒ D = (W)(T)(T)
⇒ D = (70)(4)(4)
Simplify the RHS:

find the value of x to the nearest tenth
Answer:
27
Step-by-step explanation:
So in the triangle, we've got the angle as 64°. And, there's only an opposite value and the hypotenuse value therefore the trig function is sin.
According to SOHCAHTOA,
sin=opp/ hyp
sin 64°=x / 30
Cross- multiply, then
x= 30 × sin 64°
x= 26.963
x= 27.0(nearest tenth)

x over 6 space equals space 10 over 12 ; x
Let's break this problem down in a few steps
x over 6 ⇒ x divided by 6 ⇒ [tex]\frac{x}{6}[/tex]10 over 12 ⇒ 10 divided by 12 = [tex]\frac{10}{12}=\frac{2*5}{2*6} =\frac{5}{6}[/tex]Since these two fractions are equal to each other, let's solve for x
[tex]\frac{x}{6}=\frac{5}{6} \\6x=30\\x = 5[/tex]
Thus x = 5
Hope that helps!
Answer:
[tex]x = 5[/tex]
Step-by-step explanation:
Step 1: Convert to an expression
x over 6 equals 10 over 12
[tex]\frac{x}{6}=\frac{10}{12}[/tex]
Step 2: Cross multiply
[tex](x * 12) = (6 * 10)[/tex]
[tex]12x = 60[/tex]
Step 3: Divide both sides by 12
[tex]\frac{12x}{12} = \frac{60}{12}[/tex]
[tex]x = 5[/tex]
Answer: [tex]x = 5[/tex]
