Answer:
6 hours
we see it at the x value of 6 on the graph
Step-by-step explanation:
I graphed it too using desmos then located the point where they cross, the solution point, and it was at the x value of 6 and they will have made $50 by the way in case you wanted to know that too so we see that on the graph at the point (6,50) is where they make the same amount of money.

Given:
The figure of a rhombus QRST.
To find:
A. The value of x.
B. The measure of angle RQP.
Solution:
A. We need to find the value of x.
We know that the diagonals of a rhombus are perpendicular bisectors. It means the angles on the intersection of diagonals are right angles.
[tex]m\angle RPS=90^\circ[/tex] [Right angle]
[tex](5x+15)^\circ=90^\circ[/tex]
[tex](5x+15)=90[/tex]
[tex]5x=90-15[/tex]
[tex]5x=75[/tex]
Divide both sides by 5.
[tex]x=\dfrac{75}{5}[/tex]
[tex]x=15[/tex]
Therefore, the value of x is 15.
B. We need to find the measure of angle RQP.
From the given figure, it is clear that
[tex]m\angle RQP=(2x+3)^\circ[/tex]
Putting [tex]x=15[/tex], we get
[tex]m\angle RQP=(2(15)+3)^\circ[/tex]
[tex]m\angle RQP=(30+3)^\circ[/tex]
[tex]m\angle RQP=33^\circ[/tex]
Therefore, the measure of angle RQP is 33 degrees.
n ΔHIJ, the measure of ∠J=90°, HJ = 21, JI = 20, and IH = 29. What ratio represents the cosine of ∠H?
Answer: The ratio represents the cosine of ∠H = [tex]\frac{21}{29}[/tex]
Step-by-step explanation:
Given, In right triangle ΔHIJ, the measure of ∠J=90°, HJ = 21, JI = 20, and IH = 29.
To find: The ratio represents the cosine of ∠H.
According to trigonometry, the cosine of x = [tex]\frac{\text{side adjacent to x}}{\text{Hypotenuse}}[/tex]
So cosine of [tex]\angle H=\frac{HI}{HJ}[/tex]
Cosine of [tex]\angle H=\frac{21}{29}[/tex]
hence, the ratio represents the cosine of ∠H = [tex]\frac{21}{29}[/tex]

rewrite the equation by completing the square your equation should look like (x+a)^2=b or (x-c)^2=d
What are the solutions to the equation?
Answer:
x=3+√10 or x=3−√10
Let's solve your equation step-by-step.
x2=6x+1
Step 1: Subtract 6x+1 from both sides.
x2−(6x+1)=6x+1−(6x+1)
x2−6x−1=0
For this equation: a=1, b=-6, c=-1
1x2+−6x+−1=0
Step 2: Use quadratic formula with a=1, b=-6, c=-1.
x= −b±√b2−4ac

x=
−(−6)±√(−6)2−4(1)(−1)

Step 1: Subtract 6x+1 from both sides.
x2−(6x+1)=6x+1−(6x+1)
x2−6x−1=0
For this equation: a=1, b=-6, c=-1
1x2+−6x+−1=0
Step 2: Use quadratic formula with a=1, b=-6, c=-1.

Mikes fishing lure Is 21 feet below the surface of the water how many feet does he need to reel in his lyre to reach the surface of the water?
Answer:
21 feets
Step-by-step explanation:
Since the lure is 21 feets beneath the water surface,
The the elevation of the lure is - 21 feets
If the surface of water = x
Then current distance of lure equals :
x - 21
To obtain the nunber of feets to reach the water surface ;
x - 21 = 0
x = 21 feets

Mohammed pays $569.80 for a mountain bike in a sale, the original price had been reduced by 26%, calculate the original price of the mountain bike
Answer:
$770
Step-by-step explanation:
26% off means the Mohammed paid 74% of the original price.
0.74x=569.80
x=569.8/0.74
x=770
proof:
770*0.26=200.2
770-200.2=569.8

Answer:
We need to divide.
5 1/3 divided by 1/6
(made 5 1/3 an improper fraction)
16/3 divided by 1/6
Now we make the divisor a reciprocal(meaning turning the fraction upside down)
16/3 divided by 6/1
Now we turn the division sign into a multiplication sign.
16/3 x 6/1 = 96/3 = 32 cupcakes.
Answer:
hi there user, looks like you need help!
32 cups should be the correct answer!
Step-by-step explanation:
5 1/3 ÷ 1/6 = 16/3 x 6/1 = 32

Answer:
7.76
Step-by-step explanation:
tan 29° = XY/14
XY = tan 29° (14)
= 7.76
Answer:
XY=7.76
Step-by-step explanation:
Tan25° says opp÷adj
so it's Tan29°=XY÷14
then multiply both sides by 14 to make CY the subject of the formula...
14×Tan29°=XY
therefore=XY=7.76

during a sale, a shopkeeper reduced the prices of all his goods by 15 %. Calculate the normal selling price of microwave which was sold for Rs 3825 in the sale.
Answer:
Normal selling price is Rs 4500
Explanation:
1) Selling price = original price × (100-d) / 100
d = reduced price percentage
2) Rearrange the formula
original price = (selling price × 100) / (100 - d)
S.p = 3825
d= 15%
let original price = x
Therefore
x = (s.p×100) / (100-d)
x = (3825×100) ÷ (100-15)
x = 382500/85
x = 4500
consider the original price x
offer15% = 15x/100
Saling price = x - 15x/100
3825 = 85x/100
x = (3825×100)÷ 85 = 4500 rs
Answer the normal selling price of microwave which was sold for Rs 3825 in the sale is 4500 rs
A rectangle is 21 meters long and 11 meters wide.
What is the perimeter of this rectangle?
32 m
42 m
64 m
84 m
Answer:
P = 64 meters
Step-by-step explanation:
P = 2(l+w) for a rectangle
Substitute in the length and the width
P = 2( 21+11)
P = 2( 32)
P = 64 meters
Answer:
P = 2(l+w)
= 2 ( 21+11)
= 2(32)
= 64m

Find the value of x
Please help out!!
Answer:
x = 12
Step-by-step explanation:
(2x + 4) and (12x + 8) are same- side interior angles and sum to 180° , then
2x + 4 + 12x + 8 = 180
14x + 12 = 180 ( subtract 12 from both sides )
14x = 168 ( divide both sides by 14 )
x = 12
How are formulas for the volume of a cylinder, pyramid, and cone derived?
Answer:
Calculus-based analytic geometry makes the cylinder, pyramid, and cone from "solids of revolution". From there, they can measure the length or radius of the base, and then the height. This is true even if the solid of revolution is along the X axis intead of the Y axis. Then someone "figured out" the formula, just like they did with a cube, and proved it.
The volume of a cylinder is 3,166.7 cm2. The radius of the base of the cylinder is 6 cm. What is the height of the cylinder?
Answer:
the height of the cylinder is 28cm

A patio is shaped like the figure shown below with the length of each square
equal to 1 meter. Anthony wants his patio to look awesome therefore he will
cover it with tiles. The tiles cost $4 per meter square. How much will it cost to
cover the patio with tiles? (Hint: Find the area of the composite figure then
multiply it by 3)
Answer:
[tex]\$ 80[/tex]
Step-by-step explanation:
Since we know the price per square meter, we can find area of the figure and multiply it by the price per square meter.
The area of the composite figure consists of a trapezoid and a rectangle.
Area of trapezoid: [tex]\frac{(8+4)}{2}\cdot 2=6\cdot 2 = 12\:\mathrm{m^2}[/tex]
Area of rectangle: [tex]4\cdot 2=8\:\mathrm{m^2}[/tex]
Therefore, the area of the composite figure is equal to [tex]12+8=\boxed{20\:\mathrm{m^2}}[/tex]. Since the problem states that it will cost Anthony $4 per square meter, the total cost to tile the entire figure will be [tex]20\cdot 4=\boxed{\$80}[/tex]
