. You can buy 2 ice cream cones for $3.00 or 4 ice cream cones for $7.00. Which is the better buy? *Hint: First write the rate as a fraction. Remember, money always goes in the numerator. Now find the unit rate by dividing the numerator by the denominator.
Answer:
The better buy is 2 ice cream cones for $3.00
Step-by-step explanation:
Step one:
given
You can buy 2 ice cream cones for $3.00
let us solve for the unit cost
3/2= $1.5 per ice cream cone
Step two:
You can buy 4 ice cream cones for $7.00
let us solve for the unit cost
7/4= $1.75 per ice cream cone
The better buy is 2 ice cream cones for $3.00 because a cone is $0.25 less expensive than 4 ice cream cones for $7.00.
A) Find dy for 4y - 3xy + 8x = 0 and b) evaluate dy for x = 0 and dx = 0.05
Compute the differential for both sides:
4y - 3xy + 8x = 0
→ 4 dy - 3 (y dx + x dy) + 8 dx = 0
Solve for dy :
4 dy - 3y dx - 3x dy + 8 dx = 0
(4 - 3x) dy + (8 - 3y) dx = 0
When x = 0, we have
4y - 3•0y + 8•0 = 0 → 4y = 0 → y = 0
and with dx = 0.05, we get
(4 - 3•0) dy + (8 - 3•0) • 0.05 = 0
→ 4 dy + 0.4 = 0
→ 4 dy = -0.4
→ dy = -0.1

A candle that is 8 inches tall burns at a rate of 3/4 inches per hour. Find the height of the candle after 4 hours.
Answer:
5 inch
Step-by-step explanation:
so its 3/4 per hour, so multiply it by 4 (since it had been burning for 4 hours) and that is 3 inches. 8-3 is 5, so 5 inches
Determine the relationship between the given linear functions:
Line A: 4y - 12x = 20
Line B: 3y = -x + 2
9514 1404 393
Answer:
the lines are perpendicular
Step-by-step explanation:
When both equations are written in standard form, they are ...
y -3x = 5
3y +x = 2
The coefficients in one of these equations are swapped, and one is negated, relative to the coefficients in the other equation. This means the lines are perpendicular (their slopes are opposite reciprocals).
A graph confirms this relationship.

find the coordinates of point which divides the line segment joining the points (a+b,a-b) and (a-b,a+b) in the ratio 3:2 interally
Answer:
Coordinate of 0 = [tex]\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)[/tex]Step-by-step explanation:
Let AOB be the line segmentPoint 'O' divides the line segment into m:n = 3:2Given:
Coordinate of a = (a+b, a-b)Coordinate of b = (a-b, a+b)Ratio = 3:2ToFind:
Coordinate of 0 (zero)Solution:
ATQ,
[tex]\dfrac{m}{n}=\dfrac{3}{2}[/tex]Coordinate of a = (x[tex]_{1}[/tex], y[tex]_{1}[/tex])Coordinate of b = (x[tex]_{2}[/tex], y[tex]_{2}[/tex])As we know that,
[tex]\implies\:\:x = \dfrac{mx_{2} + nx_{1}}{m + n}[/tex]
[tex]\implies\:\:x = \dfrac{(a-b)3 + (a+b)2}{3+2}[/tex]
[tex]\implies\:\:x = \dfrac{3a - 3b + 2a + 2b}{5}[/tex]
[tex]\implies\:\:\red{x = \dfrac{5a - b}{5}}[/tex]
Similarly,
[tex]\implies\:\:y = \dfrac{my_{2}+ny_{1}}{m+n}[/tex]
[tex]\implies\:\:y = \dfrac{(a+b)3+(a-b)2}{3+2}[/tex]
[tex]\implies\:\:y = \dfrac{3a+3b+2a-2b}{5}[/tex]
[tex]\implies\:\:\red{y = \dfrac{5a+b}{5}}[/tex]
Hence,
Coordinate of 0 is [tex]\blue{\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)}[/tex]

Answer:
C. a=12ft, b=12ft
Step-by-step explanation:
This is a 45*-45*-90* triangle
"a" and "b" are the same
and the hypotenuse (which is 12 square roots of 2) is square root of 2 times as long as each leg.
so the answer must be:
a = 12ft, b = 12ft

A road crew uses the triangles shown in the diagram to
measure the width of a sinkhole across a highway from a safe
distance away. How wide is the sinkhole?
Answer:
18 ft
Step-by-step explanation:
Both triangles shown are congruent.
By the concept of transversal lines and vertically opposite angles, we conclude that the width of the sinkhole is 18 feet.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know when a transversal intersects a parallel line vertically opposite angles are equal and we also know that sides opposite to similar angles have the same length.
∴ The width of the sinkhole is also 18 feet.

Answer:
The shopper should but the 6 pcs pack because its cheaper.
Step-by-step explanation:
6-pcs pack = $2.10
hot dogs needed = 48
number of 6 pcs = 48 divided 6 = 8
total cost = $2.10 x 6 = $16.80
8 pcs pack = $3.12
hot dogs needed = 48
number of 8 pcs packs = 48 divided 8= 6
total cost = $3.12 x 6 =$18.72

O A. 298 units2
OB. 840 units2
O C. 480 units2
O D. 420 units2
Answer:
480 units^2
Step-by-step explanation:
5 * 12 = 60
13 * 14 = 182
12 *14 = 168
5 * 14 = 70
480
The surface area of the given prism will be 480 square units so the correct answer is option C.
What is surface area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
The triangular prism is having 6 surfaces so the surface area will be the sum of the area of all the sides of the prism.
The area of all the sides of the prism will be calculated as follows:-
5 x 12 = 60
13 x 14 = 182
12 x 14 = 168
5 x 14 = 70
The total surface area of the prims will be:-
SA of prism = 60 + 182 + 168 + 70 = 480 square units
Therefore the surface area of the given prism will be 480 square units so the correct answer is option C.
