April measured her bed and made a scale drawing. The scale of the drawing was 1
centimeter = 6 inches. In the drawing, the bed is 10 centimeters long. What is the
length of the actual bed?
Answer:
60 inches
Step-by-step explanation:
Given data
We have the scale of the drawing as
1cm= 6 inches
Now if 1 cm is equivalent to 6inches
then 10cm will be x inches
Cross multiply we have
x*1= 10*6
x= 60 inches
Hence the length of the actual bed is 60inches

The line x = k intersects the graph of the parabola x = -2y^2 - 3y + 5 at exactly one point. What is k? Thank you! :)
Answer:
49/8 is the value of k
Step-by-step explanation:
We have the system
x = -2y^2 - 3y + 5
x=k
We want to find k such that the system intersects once.
If we substitute the second into the first giving us k=-2y^2-3y+5 we should see we have a quadratic equation in terms of variable y.
This equation has one solution when it's discriminant is 0.
Let's first rewrite the equation in standard form.
Subtracting k on both sides gives
0=-2y^2-3y+5-k
The discriminant can be found by evaluating
b^2-4ac.
Upon comparing 0=-2y^2-3y+5-k to 0=ax^2+bx+c, we see that
a=-2, b=-3, and c=5-k.
So we want to solve the following equation for k:
(-3)^2-4(-2)(5-k)=0
9+8(5-k)=0
Distribute:
9+40-8k=0
49-8k=0
Add 8k on both sides:
49=8k
Divide both sides by 8"
49/8=k
Find x. Round to the nearest tenth: 29 500 ft
Answer:
437.3ft
Step-by-step explanation:
last of sines
a/sin(A) = b/sin(B) = c/sin(C)
sin(90) = 1
the angle between y and 500ft side is 90-29 = 61 degrees.
so,
x/sin(61) = 500/1 = 500
x = 500 × sin(61) = 437.3ft
In a triangle, value of [tex]x = 437.4[/tex] units (round to nearest tenth) using trigonometric ratio.
What is trigonometric ratio?"Trigonometric ratio is defined as in a right triangle the relation between the ratio of a sides of a triangle and the angle."
Formula used
[tex]sin\theta = \frac{opposite sides}{hypotenuse}[/tex]
[tex]cos\theta = \frac{adjacent sides}{hypotenuse}[/tex]
According to the question,
In a given right triangle ABC,
Hypotenuse [tex]=500 ft[/tex]
Opposite side [tex]= x ft[/tex]
Adjacent side [tex]= y ft[/tex]
As per the diagram drawn,
[tex]\angle BAC+ 29\° = 90\° \\\\\implies \angle BAC = 90\° -29\° \\\\\implies \angle BAC = 61\°[/tex]
Substitute the value in the above trigonometric ratio formula we get,
[tex]sin61\° = \frac{x}{500}\\\\\implies 0.8747 = \frac{x}{500}\\\\\implies x = 500 \ times 0.8747\\\\\implies x = 437.35 ft[/tex]
[tex]\implies x = 435.4 ft[/tex] (round to nearest tenth)
In trigonometric ratio [tex]cos\theta[/tex] we get,
[tex]cos61\° = \frac{y}{500}\\\\\implies 0.4848 = \frac{y}{500}\\\\\implies y= 500 \ times 0.4848\\\\\implies y = 242.2 ft[/tex]
Hence , In a triangle, value of [tex]x = 437.4[/tex] units (round to nearest tenth) using trigonometric ratio.

C = 2πr
C = 2 * 3.14 * 1.5
C = 3.14 * 3

4.71 ft + 3 = 7.71 ft
Area:
A = πr²
A = 3.14 * 2.25
A = 7.065 ft²
7.065 ft² = 3.5 + 0.0325 = 3.5325 ft²

What is the measure of angle B
Answer:
Step-by-step explanation:
angle C + Angle B= Angle A(sum of two interior oppposite angles are equal to the exterior angle formed)
61+B=143
B=143-61
B=82 degree
We know that,
→ C = 61°
[A = B + C]
→ 143° = B + 61°
→ B = 143° - 61°
→ B = 82°
[180° = A + B + C]
→ 180° = A + (82° + 61°)
→ A = 180° - 143°
→ A = 37°
A car tire with a diameter of 1.6 ft rotates 275 degrees . How far does a point on the circumference of the tire travel
Answer:
A point on the circumference of the tire will travel 7.68 ft.
Step-by-step explanation:
Given;
radius of the car tire, r = 1.6 ft
angular distance or rotation = 275⁰
A complete rotation of the tire = 360⁰
the distance a point on the circumference will travel = 2πr
If 360⁰ = 2πr
then 275⁰ = ?
[tex]= \frac{275 \ \times \ 2\pi r}{360} = \frac{275 \ \times \ 2\pi \times 1.6ft}{360} = 7.68 \ ft[/tex]
Therefore, a point on the circumference of the tire will travel 7.68 ft.

7.5cm2
Step-by-step explanation:
5x3cm=15cm2 because of base x height/2 you would do
15cm2 divided by 2 since it is a triangle (a half of a square) which is 7.5cm2
Answer:
D.
Step-by-step explanation:
Area of a triangle is bh/2
So your base is 5 and your height is 3.
So you do 5*3 which is 15.
And lastly you do 15/2, which is 7.5. 7*2 is 14, and 8*2 is 16
So 7.5 times 2 is 15

Can someone please help me this?
Answer:
Yes
Step-by-step explanation:
We can make one equation other to the other to solve for x-value first;
=> -4x = x - 5
=> -4x + (-x) = -5
=> -5x = -5
=> x = -5/-5
=> x = 1
Once we have the x-value we can substitute it in for "x" in any equation to find the y-value;
=> y = x - 5
=> y = (1) - 5
=> y = -4
Writing the answer coordinate points would look like (x, y) which would be (1, -4) which is similar to the give, there for yes the solution to the equations is the given coordinate.

⚠️❗️⚠️❗️⚠️❗️ 10 POINTS what's the area
Answer:
263(usually it would say cm or m)²
Step-by-step explanation:
area = l x w
l= 25
w= 19
25 x 19 = 551
thats the area without subtracting the missing area's.
missing area= 9 x 16
=144
since theres 2 areas missing, times it by two
144 x 2
=288
subtract the missing area from the total because its not there.
551 - 288
= 263

Determine whether the lines given by the fallowing equations intersect at (-1/4,3/4) show all work. 4x+8y=5, x-3y= -3
Answer:
(0, 1)
Step-by-step explanation:
First, we need to make y the subject of the formula from both expressions
For 4x+8y=5
8y = 5- 4x
y = (5-4x)/5
Similarly for x-3y= -3
-3y = -3 - x
3y = x+3
y = (x+3)/3
Since both lines intersects, hence;
(5-4x)/5 = (x+3)/3
Cross multiply
5(x+3) = 3(5-4x)
5x + 15 = 15 - 12x
5x + 12x = 15 - 15
17x = 0
x = 0/17
x = 0
Sustitute x = 0 into any of the equations
Given that y = x+3/3
y = 0+3/3
y = 3/3
y = 1
This shows that the lines intesects at (0, 1)
