180 - 64= 116
116 divided by 4 = 29
x=29
Have a good day:>
Answer:
x = 29
Step-by-step explanation:
Supplementary angles add up to 180 degrees:
4x+64 = 180
Subtract 64 from both sides:
4x+64-64 = 180-64
4x = 116
Divide both sides by 4:
4x/4 = 116/4
x = 29

Find the missing side length.
Please I need help, also need explanation.
Thank you!!
Answer:
x=2
y=√2
Step-by-step explanation:
You can tell from the angles that this is a 45, 45, 90 triangle. That would mean that the side given is x. Then the side "x" is x√2, and "y" is the same as x. So, that would mean the sides would be √2, √2, and 2.
Right triangle XYZ is drawn with a 23° angle. For right triangles with an angle of 23° the ratio of the leg adjacent the 23° angle compared to the hypotenuse is 0.92 If the leg adjacent to the 23° angle has a length of 46 units, what is the length of the hypotenuse?
Answer:
50
Step-by-step explanation:
In a right angled triangle :
Ratio of the leg Adjacent an angle to the hypotenus can be obtained using the Cosine trigonometric ratio
For an angle of 23° and and adjacent leg of 46
Cos 23 = adjacent / hypotenus
Adjacent / hypotenus = 0.92
46 / hypotenus = 0.92
Hypotenus = 46 / 0.92
Hypotenus = 50
Work out 3 times 10^5 divide by 4 times 10^3
Give your answer as an ordinary number
Answer:
75
Step-by-step explanation:
Answer:
75,000,000
Step-by-step explanation:
first what we do is we do 10^5 which could also be seen as
10*10*10*10*10=100,000
now we times that by 3
100,000*3=300,000
and now divide by 4
300,000÷4=75,000
now times 75,000 by 10^3 (10*10*10=1,000)
75,000*1,000=
75,000,000
75,000,000 is your answer

A stereo uses 150 watts of electricity. How much CO2 is produced by using the stereo for
8 hours?
1.2 lb
0.2055 lb
1,644 lb
1.644 lb
Answer:
mCO₂ = 1.188 lb or simply 1.2 lb
Step-by-step explanation:
We need to use the following expression:
E = P * t
Where:
E: Energy in Kwh
P: Power in Watts
t: time in hours.
Applying this, with the given data we have:
E = 150 * 8
E = 1200 watts . h
Converting this value in kW we have:
E = 1200 watts * 1 kW/1000 watts = 1.2 kWh
In general terms, we have 0.99 pounds of CO₂ emissions per kWh, so with the obtained value we have:
mCO₂ = 0.99 * 1.2
mCO₂ = 1.188 lb or simply 1.2 lbHope this helps
Using the work shown on the left, What is the cubed root of 4/ the square root of 2 in simplest radical form

Mr. Garner purchased a party hall and wants to repaint it as part of the renovations. He needs to calculate the lateral surface area of the party hall so that he will know how much paint to buy. The party hall is in the shape of a rectangular prism with the dimensions shown below. Including the doors, what is the lateral surface area of the party hall in square feet?
Answer:
The lateral surface area of the rectangular prism is 204 square feet
Step-by-step explanation:
The remaining part of the question is attached
Solution
Lateral surface area of a rectangular prism is
Height of the prism * perimeter of the base of the prism.
Substituting the given values, we get-
Lateral surface area of a rectangular prism =
[tex]0.5 *12 * 2(12+5)\\0.5*12*2*17\\0.5*408 \\204[/tex]
The lateral surface area of the rectangular prism is 204 square feet

Millie has an interview for a job. She is driving to the interview. There are 3 sets of traffic lights on her route. There is a fifty/fifty chance of the lights being red or green.
What are the chances of Millie getting 3 consecutive green lights?
Answer: 0.125
Step-by-step explanation:
Since there is a fifty/fifty chance of the lights being red or green, therefore, the chances of Millie getting 3 consecutive green lights will be:
= (50%)³
= 0.5³
= 0.5 × 0.5 × 0.5
= 0.125
Therefore, the probability is 0.125

Jerome, kevin and seth shared a submarine sandwhich. Jerome ate 1/2 of the sandwich , kevin ate 1/3 of the sandwich, and seth ate the rest. What is the ratio of jerome's share to kevin's share to kevin's share to seth's share?
Given:
Jerome ate 1/2 of the sandwich , Kevin ate 1/3 of the sandwich, and Seth ate the rest.
To find:
The ratio of jerome's share to kevin's share to seth's share.
Solution:
Jerome ate 1/2 of the sandwich. So,
Jerome's share = [tex]\dfrac{1}{2}[/tex]
Kevin ate 1/3 of the sandwich. So,
Kevin's share = [tex]\dfrac{1}{3}[/tex]
Seth ate the rest. So,
Seth's share = [tex]1-\dfrac{1}{2}-\dfrac{1}{3}[/tex]
= [tex]\dfrac{6-3-2}{6}[/tex]
= [tex]\dfrac{1}{6}[/tex]
The ratio of jerome's share to kevin's share to seth's share is:
[tex]\dfrac{1}{2}:\dfrac{1}{3}:\dfrac{1}{6}[/tex]
To simplify the ratio multiply the ratio by 6.
[tex]\dfrac{1}{2}\times 6:\dfrac{1}{3}\times 6:\dfrac{1}{6}\times 6[/tex]
[tex]3:2:1[/tex]
Therefore, the ratio of jerome's share to kevin's share to seth's share is 3:2:1.

Yesterday, Claudia ran 1/9 of a mile. today she ran 3/4 of a mile. how far did she ran all together?
Answer:
31/36
Step-by-step explanation:
1/9 + 3/4 = convert the denominators with finding a common multiple of 9 first = 9 x 4 = 36
9 x 4 = 36 and 4 x 9 = 36
?/36
Then convert the numerators with the numbers you bolded
1 x 4 = 4
and 3 x 9 = 27
= 4/36 + 27/36 = 31/36

Analia has $550 in her checking account. She wants
to spend part of this money on a VR-Headset. She
wants to have at least $225 left in her checking
account after buying a VR-Headset. The inequality
shown can be used to find t, the amount of money
in dollars that Analia can spend on a VR-Headset.
Solve the inequality.
t + 225 ≤ 550
Answer:
t ≤ 325
Step-by-step explanation:
the inequality: t+225 ≤ 550
t ≤ 550-225
Subtract 225 from 550
t ≤ 325 :)
