A car travels 60 miles in 50 minutes. Calculate the average speed of the car in mph.
Answer:
1.2mph
5x10=50
so it 1
if 2x5=10=.2
then 2x5=10+50=1.2 due to the .1=5
or just do 60/50=1.2

Answer:
y = 5√3
x = 10√3
Step-by-step explanation:
From the given sides
Adjacent = 15
Opposite = y
Hypotenuse = x
Angle of depression = 30degree
Using the SOH CAH TOA identity
tan theta = opp/adj
tan 30 = y/15
y = 15tan30
y = 15(1/√3)
y = 15√3/3
y = 5√3
Similarly
cos theta = adj/hyp
cos 30 = 15/x
x = 15/cos30
x = 15 /√3/2
x = 30/√3
x = 30√3/3
x = 10√3
Find the values of x and y
Answer:
x = 54, y = 63
Step-by-step explanation:
117° and the left base angle are adjacent and sum to 180°
base + 117° = 180° ( subtract 117° from both sides )
base = 63°
Since the triangle is isosceles ( congruent legs ) then the 2 base angles are congruent , so y = 63
and x = 180 - (63 + 63) ← sum of angles in a triangle
x = 180 - 126 = 54

A sphere fits inside a cube with the sphere's diameter equal to the width of the cube, 20 centimeters. What is the volume of the cube not filled by the sphere? Round to the nearest cm³
A) 3813cm³
B) 3225cm³
C) 4079cm³
D) 3546cm³
The volume of the cube not filled by the sphere is 3811.209. Option A is the correct.
What is volume?The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic m.
The volume of sphere is found as;;
[tex]\rm V_{sphere}= \frac{4}{3} \pi r^3 \\\\ V_{sphere}= \frac{4}{3} \times 3.14 (10)^3 \\\\ V_{sphere}= 4188.79 \ cm^3[/tex]
The volume of cube is found as;
Volume of cube = Length x width x height
Volume of cube =20 x 20 x 20
Volume of cube = 8000
The volume of the cube not filled by the sphere is found by subtract the volume of the cube by the volume of the sphere.
V=8000 - 4188.790205
V = 3811.209
The volume of the cube not filled by the sphere is 3811.209.
Hence, option A is the correct.

Terry has a number cube that is numbered from 1 to 6. She rolls the cube 50 times. Which equation can be used to predict the number of times that she will roll a number that is greater than 4?
(options in picture)
I have around 40 minutes so its not too much of a rush, Thank you! :)
Answer:
P(number greater than 4) = 1/6(50)
In numbers 1 to 6 only 5 and 6 are greater than 4.
Hence, the probability that she will get a number greater than 4 is 2 out of 6 or 2/6.
________________________________
The probability that she'll get more than 4 if she throws the dice 50 times–
The probability that she'll get more than 4 if she throws the dice 50 times–= 50 × 2/6________________________________
Hence, your answer will be–
Hence, your answer will be–P( Number greater than 4 ) = 2/6 (50)

HURRY IM BEING TIMED! The line of best fit for this scatter plot shows the relationship between the average temperature and the monthly electricity bill at Jenny’s house.
Answer:
[tex]y = \frac{11}{8}x + 50[/tex]
Step-by-step explanation:
Given
See attachment for plot
Required
The line of best fit
From the attached plot, we have:
[tex](x_1,y_1) = (0,50)[/tex]
[tex](x_2,y_2) = (80,160)[/tex]
Calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{160 - 50}{80-0}[/tex]
[tex]m = \frac{110}{80}[/tex]
[tex]m = \frac{11}{8}[/tex]
The line of best fit is then calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = \frac{11}{8}(x - 0) + 50[/tex]
[tex]y = \frac{11}{8}x + 50[/tex]
Answer:
The electricity bill will be about $200 when the average temperature reaches 100°F.
I need help on this
Answer:
1200
Step-by-step explanation:
Step 1 convert pounds to ounces
1 pound = 16 ounces
So to convert pounds to ounces we multiply by 16
1500 * 16 = 24000
So there are 24000 ounces in 1500 pounds
Step 2 Find how many 20 ounce containers he can fill.
To find out how many 20 ounce containers he can fill we divide the total amount of ounces of butter that he has by 20
So answer = 24000/20
24000 / 20 = 1200
Therefore he can fill 1200 20 - ounce containers

Round 8.157 to the nearest hundredth.
Answer:
I believe the answer is 8.16 pardon me if it's wrong.
Answer:
8.18
Step-by-step explanation:
First, note that 8.175 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 8
Fractional Part: 175
To round 8.175 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part.
We use the following rules to round 8.175 to the nearest hundredth:
A) If the last digit in the fractional part of 8.175 is less than 5, then simply remove the last the digit of the fractional part.
B) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit.
C) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is less than 9, then add 1 to the first digit in fractional part and make the second digit in fractional part 0. Then remove the third digit.
D) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is 9, then add 1 to the integer part and make the fractional part 00.
With 8.175, rule B applies and 8.175 rounded to the nearest hundredth is:

What is the distance between the two points 5,3 and (1,0)?
Answer: The distance between (5,3),(1,0) is 25units square.
Step-by-step explanation:
So, I usually plot the points, and conect them first.
And then I draw a right triangle, so draw two line that conect to the line that we need to find the distance, and form a triangle. Make sure that the line from point (5,3)(1,0) is the Pythagorean triples.
Next, you count the units of the two line that makes a right angle. which is 4 units for the first line, and 3 units for the second.
Thirdly, you plug the numbers into the Pythagorean equation, which is a^2+b^2=c^2 (plug it into a and b, it doesn't matter which number for which letter)
4^2+3^2=c^2
16+9=c^2
25=c^2
[tex]\sqrt{25}[/tex] = [tex]\sqrt{c}[/tex]
c=25
