Answer:
[tex]x=60^{\circ}[/tex]
Step-by-step explanation:
The angle formed by [tex]48+x[/tex] and the angle marked as [tex]72^{\circ}[/tex] are co-interior angles and therefore must be supplementary (add up to 180 degrees).
Therefore, we have:
[tex]48+x+72=180,\\x+120=180,\\x=\boxed{60^{\circ}}[/tex]
the answer in the problem is 0.75
Answer:
0.75
Step-by-step explanation:
you said it was 0.75
If 9 exercise books cost
$540.00. how much will
14 of such cost?
Answer:
$840 dollars
Step-by-step explanation:
Divide 540 by 9 to get the cost of 1 book then multiply it by 14
Answer:
$840
Step-by-step explanation:
[tex]\frac{14}{9}: \frac{y}{540}[/tex]
y × 9 = 540 × 14
9y = 7560
9y ÷ 9 = 7560 ÷ 9
y = 840

12(4x−5)+5/2=10 solve for x pls help!!!!
Answer:
Step-by-step explanation:
[tex]12(4x - 5) + \frac{5}{2}=10[/tex]
Multiply the whole equation by 2
[tex]2*12(4x -5) + \frac{5}{2}*2=10*2\\\\24(4x-5) + 2 = 20\\[/tex]
24*4x - 5*24 + 2 = 20
96x - 120 + 2 = 20
96x - 118 = 20
Add 118 to both sides
96x = 20 +118
96x = 138
Divide both sides by 96
x = 138/96 = 23/16
[tex]x = 1 \frac{7}{16}[/tex]

At what position on the number line is the red dot located
Answer:
A
Step-by-step explanation:
Write an equation in slope intercept form of the line that passes through the points (1,−6) and (5,−6).
slope intercept form = y=mx+b
m= slope
b= y-intercept
the slope is rise over run, so if the points are (1, -6) and (5, -6), the slope is 0
the y intercept is -6
y = 0x-6
or
y = -6

What is the area❓ No links or troll answers you’ll be reported
Answer:
103
Step-by-step explanation:
Find the area of the rectangle on the top
A = 7*13 = 91
Now find the area of the rectangle on the bottom
13 - (5+5) = 3
11-7 = 4
The dimensions of the bottom rectangle are 3 by 4
A = 3*4 = 12
The total area is 91+12 = 103
After that incident, the Civil defense team decided to buy new trucks with ladders higher than 100 feet. They found 2 different trucks with same height of ladders. The first truck costs $145,000 and will cost $0.31 per mile traveled based on the current gas prices. The second truck will cost $160,000 but gets better gas mileage, costing $0.27 per mile. They need to decide which truck is the best deal.
1. Write an equation that represents the total cost of each truck.
2. How many miles the trucks will have to drive for the costs of the trucks to be equal?
3. Which truck should the Civil defense team buy? Explain your reasoning using Mathematical terms.
Answer:
Step-by-step explanation:
the cost difference between the first truck and the second truck = $160,000-$145,000 = $15,000
the difference of gas cost between the first truck and the second truck = $0.31 - $0.26= $0.05 per mile.
so,
I think, this is a very significant number of truck cost compared with gas cost
for the best deal, the first truck is the best choice.
Hope this answer helps you :)
Have a great day

Answer:
buy truck 2 since it cheaper
, if u do it in a graph after they intersect usee that truck num 1 increases while truck num 2 decreases
Step-by-step explanation:
1.
First Truck: Y = 0.31x + 145,000
Second Truck: Y = 0.27x + 160,000
2.
Y = 0.31x + 145,000
Y = 0.27x + 160,000
- 0.31x + y = 145,000
- 0.27x + y = 160,000
- 0.31x + y = 145000
0.27x – y = -160000
- 0.04 = -15000
X=375000
- 0.31 x 375000 + y =145000
Y = 261250
(x , y) = (375000 , 261250)

Step-by-step explanation:
A painting without its frame has a width 2.5 times its height, h, in inches. Its frame is 3 in. wide all along its perimeter. What is an expression for the area of the framed painting in terms of h? A. 2.5h2 B. 2.5h2 + 6 C. 2.5h2 + 36 D. 2.5h2 + 21h + 36
Answer:
2.5h^2 + 21h + 36
Step-by-step explanation:
Height = h
width = 2.5h
border = 3 in.
Overall height = h+6
Overall width = 2.5h+6
Overall area
= (h+6)(2.5h+6)
= 2.5h^2 + 15h + 6h +36
= 2.5h^2 + 21h + 36

You buy a car for 20,000 dollars and pay 5% in tax. How much is the tax?
Answer: $1,000
Step-by-step explanation:
We are trying to find 5% of 20,000. Always remember that the "of" can be changed to a multiplication, and that "percent" means per hundred. So you will write (5/100) x 20,000 = 0.05 x 20,000 = $1,000.00

Escriba larazon entre la distancia (d)recorrida por un automóvil y el tiempo (t)empleando velocidad (v) es una razón entre distancia y el tiempo y de valor de su velocidad v=d/t
Answer:
V = d / t
Step-by-step explanation:
La velocidad se define como la relación entre la diatancia cubierta por un cuerpo y el tiempo necesario para cubrir esa distancia.
Si el tiempo empleado se da como (t)
La distancia recorrida se da como (d)
Podemos escribir la velocidad (V) en términos de disance y tiempo como;
V = d / t

*PLS HELP WILL MARK BRAINLIEST 100 POINTS* A moving truck 7 feet wide and 13 feet high is approaching a semi-circular brick archway. The base of the
archway is 28 feet wide. The road under the archway is divided, allowing for two-way traffic. If the truck remains just
to the right of the median, will it be able to pass under the archway without damage?
Answer:
No
Step-by-step explanation:
Think of the archway as a semicircle with a radius of 28/2 = 14
The diagonal of the truck is like the hypotenuse of a right triangle with legs of 7 and 13
c² = a² + b²
c² = 7² + 13²
c² = 49 + 169
c² = 218
c = 14.76
Since the diagonal of the truck is greater than the radius of the arch the truck will NOT pass without damage
heyy pls answer quickly i need help on math again
===========================================================
Explanation:
y = 5 because the long leg is exactly sqrt(3) times that of the short leg.
The short leg is always opposite the 30 degree angle.
The hypotenuse x is twice that of y, so x = 2y = 2*5 = 10
All of these rules only apply to 30-60-90 triangles. You can use trig ratios as an alternative route.
