During summer months, one ice cream trucks come 4 days another 5 days. If both trucks came today, when is the next time both would be here on the same day?
I have a math question
For
the first question; we have a problem dealing with translations.
Our goal is to translate
the word problem into an algebraic one. So our numbers are
60, 2, and 5. Our variable, or the letter holding the unknown
number's place
value, is
N.
The
problem states that 60 is MORE THAN the PRODUCT of 5 and N. Focus
on the words I bolded and capitalized. These are your key words that
tells you what operations
you need to use. Note that 'product' signals the operation of
multiplication (Since the answer you get from multiplying numbers is
called the 'product'.) and
'more than' signals the operation of addition (Because you are left
off with more than you originally had before adding).
Now
that we know that our algebraic expression contains multiplication,
addition, letter N and the numbers 2 and 5; we can start plugging the
numbers in.
60
= 2 (more than) + (product of) 5N. The answer for the first
attachment is
B.
_____________________________________________________________
All
we need to do for the AB problem (Question 25 on your material) is
solve AB.
Note
1: When a problem has no operation separating two letters or numbers,
this means multiplication.
Note
2: A and B are variables. Variables are letters that stand for and
hold the place of our unknown quantities. However, the values are not
unknown anymore given the fact that the question tells us that A= 42
and B = 2. Thus we substitute A with 42 and B with 2, then work from
there. 42 * 2 =84. Answer = A.
____________________________________________________________________
And
finally, for question 26, we use PEMDAS. P = parenthesis (), E =
exponent x^2, M/D = x or /, A/S means + or subtraction.
According to PEMDAS, we first solve what's parenthesis, which is 77 – 32. Using mental math, 77 – 32 = 45. ( 7 – 3 = 4 and 7 – 2 = 5.). 5/9 * 45 is what we have left. 5 divided by 9 =0.5555555555555556. 0.5555555555555556 * 45 = 25. Answer is D.
*PLEASE HELP* BRAINLIEST* A 10% discount is offered on a certain item that sells for $10.95. How much is the discount and what is the discounted sales price?
Amount of discount =
Discounted sales price =
The amount of discount is $1.095 and the discounted sales price is $9.855.
We need to calculate the amount of discount and then subtract it from the original sales price to find the discounted sales price.
First, we calculate the amount of discount. A 10% discount on an item selling for $10.95 means we need to find 10% of $10.95. To find 10% of a number, we can multiply the number by 0.10 (which is the decimal equivalent of 10%).
Amount of discount = 10% of $10.95
= 0.10 [tex]\times[/tex] $10.95
= $1.095
Now that we have the amount of discount, we can calculate the discounted sales price by subtracting the discount from the original sales price.
Discounted sales price = Original sales price - Amount of discount
= $10.95 - $1.095
= $9.855

form an equation, using x for the unknown number and then solve it
The student's clues form the equation 3x + 4 = 22. When solved, this equation reveals that the original number x is 6.
Explanation:The student is creating an algebraic equation to find an unknown number. Starting with the clues given:
They think of a number (which we represent with x)Multiply the number by 3 (3x)Add 4 (3x + 4)The result is 22 (3x + 4 = 22)Now, we can solve this equation to find x:
Start by subtracting 4 from both sides of the equation (3x + 4 - 4 = 22 - 4)Simplify to get 3x = 18Then divide both sides by 3 (x = 18/3)This gives us x = 6 as the unknown numberLearn more about Algebra here:https://brainly.com/question/24875240

The number of CDs owned by Bryce.
O = (6+2N) / 7
And O = 30
30 = (6 + 2N) / 7 ________(3)
From (3), the value of N can be written as,
30 = (6 + 2N) / 7
Multiply both sides by 7
30 x 7 = 6 + 2N
210 = 6 + 2N
Subtract 6 on both sides.
210 - 6 = 6 + 2N - 6
204 = 2N
Divide both sides by 2.

Give an example of a linear equation perpendicular to y=5
Final answer:
A linear equation perpendicular to y=5 is a vertical line, expressed as x=c, where c is any real number. For instance, x=2 is perpendicular to y=5.
Explanation:
A linear equation perpendicular to y=5 would need to have an undefined slope, meaning it's a vertical line. Since y=5 is a horizontal line, a perpendicular line will have no slope value that we can put in terms of y=mx+b, where m represents the slope and b represents the y-intercept. Thus, the equation will be of the form x=c, where c is any real number. This represents a vertical line that crosses the x-axis at the point (c,0).
For example, the linear equation x=2 is perpendicular to y=5 and crosses the x-axis at the point (2,0).

Step-by-step explanation:
the volume of the sphere is increased by 72.8%. what is the percentage increase in the radius?
Final answer:
The volume of a sphere increases by 72.8%, which after calculations, results in a 20% increase in the radius of the sphere.
Explanation:
The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius of the sphere. An increase in volume by 72.8% implies that the new volume V' is equal to 1.728 times the original volume V. To find the percentage increase in the radius, we use the relationship between volume and radius:
V' = (4/3)πr'^3, where r' is the new radius after increase. Since V' = 1.728V, we have:
1.728 (4/3)πr³ = (4/3)π[tex]r'^3[/tex]Therefore, [tex]r'^3[/tex] = 1.728r³.After taking the cube root of both sides, we obtain:
r' = ∛1.728 * r ≈ 1.200 * rThus, the new radius is approximately 120% of the original radius, which means there is a 20% increase in the radius.
Final answer:
To calculate the percentage increase in the radius of the sphere when the volume is increased by 72.8%, we can use the formula for volume and solve for the new radius in terms of the original radius. The percentage increase in radius is then calculated by comparing the new and original radius.
Explanation:
The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius of the sphere. If the volume of the sphere is increased by 72.8%, we can calculate the new volume by multiplying the original volume by 1 + 0.728. Let's denote the original radius as r1 and the new radius as r2.
The formula for volume can be written as V = (4/3)πr³. Substituting r1 and r2 into the formula, we get:
Original volume: V1 = (4/3)πr1³New volume: V2 = (4/3)πr2³Since the two volumes are related by the percentage increase (1 + 0.728), we can write the equation:
(1 + 0.728)V1 = V2
Now, let's solve for r2 in terms of r1:
(1 + 0.728)V1 = (4/3)πr2³
r2 = ([(1 + 0.728)V1] * (3/4π))^(1/3)
Finally, we can calculate the percentage increase in the radius by comparing r2 to r1:
Percentage increase in radius = (r2 - r1) / r1 × 100%
