Answer:
x = 33.45
Step-by-step explanation:
We need to find the value of x in the given expression i.e.
[tex]\sin(42)=\dfrac{x}{50}[/tex]
Multiplying both sides by 50. So
[tex]\sin(42)\times 50=\dfrac{x}{50}\times 50\\\\x=\sin(42)\times 50\\\\x=33.45[/tex]
So, the value of x is equal to 33.45.

Answer:
The 20-count batteries have a lower unit price of $0.76 per battery
Step-by-step explanation:
Unit price means how much does it cost if you buy one of the item. To calculate this take the amount of money it cost and divide by the amount of object you have.
In the case of this question we know that you can buy 8 batteries for $6.16 and 20 batteries for $15.20. Let's find the unit cost (how much for one battery) for each of these packs. To calculate that we can take $6.16/8 batteries = $0.77 per battery for the 8 pack and $15.20/20 = $0.76 per battery for the 20 pack. Therefore, the 20-count batteries have a lower unit price of $0.76 per battery.
Janie walks 1 mile to get to a running track.she then runs at a speed of 3.5 miles per hour.Which linear models represents the total distance she ran and walked, d, as a function of t, the time she runs,in hours?
Answer:
d = 3.5t + 1
Step-by-step explanation:
The linear function would have to multiply the speed she runs at the track by the number of hours that she spent running. Then it should add this amount to the 1 mile that she walked to get to the track. If we use the variable d as the total distance that she ran and walked, and the variable t to represent time then we would create the following linear function/model.
d = 3.5t + 1

paint that covers 32.5 ft2 of surface. How can you tell that Kali has
enough paint without calculating?
Answer:
Step-by-step explanation:
If the birdhouse is a cube that is 2 ft on each edge, the surface area is 6×2² = 24 ft². That's a pretty large birdhouse, and it will need about ¾ of a pint of paint.

A total of P60,000 was invested, a portion at 5% and the remainder at 4.5%. The total amount of interest earned was P2,900. How much was invested at each rate?
Answer:
P40000 at 5%
P20000 at 4.5%
I am curious as to what the P stands for. Can you tell me?
Step-by-step explanation:
Let x = amt. invested at 5%
y = amt. invested at 4.5%
(1) x + y = 60000 (2) .05x + .045y = 2900
50x + 45y = 2900000
-45 times (1) -45x - 45y = -2700000
5x = 200000
x = 40000
40000 + y = 60000
y = 20000
P40000 at 5%
P20000 at 4.5%
I am curious as to what the P stands for. Can you tell me?

What does X and Y equal?
Answer:
X= 67
Y= 6
Step-by-step explanation:
Triangle TRU is an equilateral triangle which means all sides are equal.
Triangles sum up to 180°.
180/3= 60
60+7= 67
x=67
Triangle TRS is an isosceles triangle which means it has two equal sides.
Triangles sum up to 180°.
180-60= 120
TRS= 120°
60/2= 30°
RTS= 30°
RST= 30°
30/5= 6
y= 6
What is the value of x, if 2/5 x = 20?
Answer:

x = 10 × 5
x = 50
What do all rhombuses have in common
Every rhombus has two diagonals connecting pairs of opposite vertices, and two pairs of parallel sides.
All rhombuses have equal sides and diagonals that bisect each other at right angles.
We have,
All rhombuses have the following characteristics in common:
- Equal Sides:
A rhombus is a quadrilateral with all four sides of equal length.
Each side of a rhombus has the same measurement.
- Opposite Angles are Equal:
The opposite angles of a rhombus are congruent (equal in measure). This means that if we label the angles A, B, C, and D in a clockwise or counterclockwise direction, then angle A is congruent to angle C, and angle B is congruent to angle D.
- Diagonals Bisect Each Other:
The diagonals of a rhombus are perpendicular bisectors of each other. This means that the diagonals intersect at a right angle, and they divide each other into two equal halves.
- Diagonals are Equal in Length:
The two diagonals of a rhombus are of equal length. If we label the endpoints of the diagonals as E, F, G, and H, then EF = GH.
Thus,
All rhombuses have equal sides and diagonals that bisect each other at right angles.

D
0.5
Answer:
Step-by-step explanation:
The rate of change, slope, m is
m=(y2-y1)/(x2-x1), we have points (4,5) and (21,39) so
m=(39-5)/(21-4)
m=34/17
m=2

SA = 2tr2 + 2trh (Use 3.14 for .) How much metal is needed to create a cylindrical can with a height of 5 inches and a base diameter of 3 inches? square inches Do NOT round your answer.
Answer:
[tex]SA=61.26\ \text{inches}^2[/tex]
Step-by-step explanation:
The surface area of a cylinder is given by :
[tex]SA=2\pi r^2+2\pi rh[/tex]

if chase has 4 times as many nickels as dimes and they have a combined value of 180 cents .how many of each coin does he have ?
Help me with this question
Please I need help
Answer:
384 cm²
Step-by-step explanation:
The shape of the figure given in the question above is simply a combined shape of parallelogram and rectangle.
To obtain the area of the figure, we shall determine the area of the parallelogram and rectangle. This can be obtained as follow:
For parallelogram:
Height (H) = 7.5 cm
Base (B) = 24 cm
Area of parallelogram (A₁) =?
A₁ = B × H
A₁ = 24 × 7.5
A₁ = 180 cm²
For rectangle:
Length (L) = 24 cm
Width (W) = 8.5 cm
Area of rectangle (A₂) =?
A₂ = L × W
A₂ = 24 × 8.5
A₂ = 204 cm²
Finally, we shall determine the area of the shape.
Area of parallelogram (A₁) = 180 cm²
Area of rectangle (A₂) = 204 cm²
Area of figure (A)
A = A₁ + A₂
A = 180 + 204
A = 384 cm²
Therefore, the area of the figure is 384 cm²
