Answer:

vertical, and x is 81

Step-by-step explanation:

The angles are across first each other, which means they are the same angle. From there, set x+3 equal to 84 (x+4=84). From there solve to get x

Part of the area under this ramp serves for storage. Items can be stored only in the unshaded part of the ramp
Mekhanik [1.2K]

Answer:

48.1 m³ available, 2.5m³ not available

Step-by-step explanation:

Tan(X) = 4.5/(5.8+1.7)

Tan X = 3/5

Hypotenuse² = 3² + 5² = 34

Sin X = 3/sqrt(34)

X = 30.96

1/sinX = 1.7/SinY

Y = 61.003°

Third angle: 180 - X - Y = 88.037

Volume

= ½ × 1.7 × 1 × sin(88.038) × 3

= .

= 2.548

= 2.5m³

Available for storage:

½×4.5×7.5×3 - 2.548

= 48.077 = 48.1 m³

Please help me im crying over this question
denis23 [38]

Answer:

y = 2x - 2

Step-by-step explanation:

y= mx+b

m= slope

b= y-intercept (point on line where x= 0.... or the point where the line hits the y-axis)

Determine slope by using slope formula or by counting boxes

By counting boxes, you can see that each point is 2 units up, 1 unit right (2/1)

the slope is 2

the point where the line is touching the y-axis is (0, -2)

m = slope = 2

b  = y-intercept = -2

y = 2x + (-2) OR y = 2x -2

52.25 is ___% of 1,1050.00
USPshnik [31]

Answer: 0.4729%

Step-by-step explanation:

The formula to find the percent of a part in total amount :-

\%=\dfrac{\text{Part}}{\text{Total}}\times100

Given : Total amount = 1,1050.00

Part of total amount = 52.25

Now, substitute all the values in the formula , we get

\%=\dfrac{52.25}{11050}\times100\\\\\Rightarrow\ \%=\dfrac{5225}{1105000}\times100=\dfrac{5225}{11050}=0.472850678733\approx0.4729\%

Hence, 52.25 is <u>0.4729</u>% of 1,1050.00.

To hire a bicycle it costs $6 for each day plus a fixed charge of $15
shusha [124]

Answer:

4 days

Step-by-step explanation:

1) Derive a formula.

Let b = bicycle

Let x = the number of days

A set up equation: b = 6x + 15

2) If she pays 39 to hire a bicycle, substitute 39 into b, then solve for x.

39 = 6x + 15

39 - 15 = 6x

24 = 6x

24/6 = x

4 = x

x = 4

Since x is the number of days, she hired the bicycle for 4 days.
