A speed limit is 35 mph. A car is travelling 10 mph over the speed limit. I’d that a sum of 0
Answer:
The car is going 45 mph
Step-by-step explanation:
Since the speed limit is 35 mph and the car is 10 mph over the speed, we can add them to find out how fast the car is going. We can solve 35+10 which will give us 45. So it is not a sum of 0 but instead a sum of 45.
(hope this helped)
Answer:
35+10 =45
Step-by-step explanation:
add 10 to 35 then divide by 2

[tex]V = \frac{4}{3}\pi*r^3\\\\V = \frac{4}{3}\pi*(2t)^3\\\\\frac{4000\pi}{3} = \frac{4}{3}\pi*(2t)^3\\\\4000\pi = 4\pi*(2t)^3\\\\1000 = (2t)^3\\\\(2t)^3 = 1000\\\\(2t)^3 = 10^3\\\\2t = 10\\\\t = 5\\\\[/tex]
-----------------
Notes:
In line 2, I replaced r with 2t because the radius r is increasing at a rate of 2 cm per second. So if t is the number of seconds, then 2t is the radius in cm at time t.In line 4, I multiplied both sides by 3 to clear out the fractions. On the next line, I divided both sides by 4pi.Solve for the unknown variable and verify your answer. 2.8(3d – 2) = –12.32 *
Answer?
Answer:
-.8
Step-by-step explanation:
divide both sides by 2.8
3d-2=-4.4
add two to both sides
3d=-2.4
divide both sides by 3
d=-.8

Write an equation in slope-intercepts form for the line that passes through (5, -4) and is perpendicular to the line described by 2x-10y=0
EXPLAIN what you did in each step to arrive at your answer plz
Answer:
y = -5x + 21
Step-by-step explanation:
First, put 2x - 10y = 0 into slope intercept form to find the slope:
Subtract 2x from both sides:
-10y = -2x
Divide each side by -10:
-10y = -2x
y = 1/5x
So, the slope of the line is 1/5.
Perpendicular lines have opposite reciprocal slopes, so the slope of the other line will be -5.
Then, use the equation y = mx + b to plug in the slope and the point given.
Solve for b:
y = mx + b
-4 = -5(5) + b
-4 = -25 + b
21 = b
Lastly, plug in the slope and b into y = mx + b to create the equation in slope intercept form:
y = -5x + 21 is the equation
What are the roots of the equation x2 + 15x = -57 in simplest a + bi form?
Answer:
Step-by-step explanation:
Rewrite x2 + 15x = -57 as x^2 + 15x + 57 = 0, in which the coefficients of this quadratic are {1, 15, 57}.
Then the discriminant is b^2 - 4ac = 225 - 4(1)(57) = -3
Because the discriminant is negative, we know that the two roots will be complex. They are:
-15 ±i√3

Answer:
x = -7.5 ± i(√3)/2
Step-by-step explanation:
We can add (15/2)² to complete the square:
x² +15x +(15/2)² = -57 +(15/2)²
(x +7.5)² = -0.75
x +7.5 = ±i(√3)/2 . . . . take the square root
The roots are ...
[tex]x=\displaystyle\left \{ {{-\dfrac{15}{2}+i\dfrac{\sqrt{3}}{2}} \atop {-\dfrac{15}{2}-i\dfrac{\sqrt{3}}{2}}} \right.[/tex]

How would i know if a line on a graph has passed the vertical line test?
Answer:
The vertical line will only pass the graph line once.
Step-by-step explanation:
For example, I found an example online. The vertical line intersects a circle twice. But on a horizontal squiggly line, it only touches it once. So the circle is NOT a function but the squiggly line IS a function.

Which fraction represents the solution to -6/5/(-3/25) in simplest form?
A. -10
B. -18/125
C. 10
D. 18/125
The fraction represents the solution to (-6/5)/(-3/25) in the simplest form will be 10. Then the correct option is C.
What is Algebra?Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to answer the problem correctly and precisely.
The fraction numbers are given below.
-6/5 and -3/25
Then the division of the numbers -6/5 and -3/25 will be given by putting a division sign between them. Then we have
⇒ (-6/5) ÷ (-3/25)
⇒ (-6/5) / (-3/25)
⇒ (6/5) x (25 / 3)
⇒ 150 / 15
⇒ 10
The part that addresses the answer for (- 6/5)/(- 3/25) in the most straightforward structure will be 10. Then the right choice is C.

Given :
Ellis is making some beef burgers for his friends.
His recipe 500g of beef mince and 120g of cheese to make four burgers.
He buys 1.5 of mince and 400g of cheese, and makes as many burgers as possible.
To Find :
How much cheese will he have left over.
Solution :
500 g and 120 g of beef mince and cheese respectively make 4 burgers.
125 g and 30 g of beef mince and cheese respectively make 1 burgers.
Now, we will keep increasing the ingredients until there is any shortage of any ingredients.
1000 g and 240 g will make 8 burgers.
1500 g and 360 g will make 12 burgers.
1625 g and 390 g will make 13 burgers.
Cheese left is ( 400 - 390 ) g = 10 g.
Therefore, 10 grams of cheese will be left.
