3. To break the school's record, the girls' time had to be faster than 12 2/5minutes. Did the girls break the record? If so, how much faster werethey? If not, how much slower were they?
ANSWER
The girls did not break the record
STEP-BY-STEP EXPLANATION:
Given information
\(\begin{gathered} Barbara\text{ spent }3\frac{3}{10}\text{ minutes to complete the relay race} \\ \text{Donna spent 2}\frac{4}{5}\text{ minutes to complete the relay race} \\ \text{ Cindy spent x minutes to complete the relay race} \\ \text{ Nicole spent }2\frac{1}{10}\text{ minutes to complete the relay race} \end{gathered}\)From the question provided, the record set by the school is 12 2/5 minutes
The next step is to find the time spent by Cindy in the relay race
\(\begin{gathered} 3\frac{3}{10}\text{ + 2}\frac{4}{5}\text{ + x + 2}\frac{1}{10}\text{ = 12}\frac{2}{5} \\ \text{The next process is to convert the mixed fraction into an improper fraction} \\ \frac{33}{10}\text{ + }\frac{14}{5}\text{ + x + }\frac{21}{10}\text{ = }\frac{62}{5} \\ \text{let the co}mmon\text{ denominator be 10} \\ \frac{33\text{ + 14(2) + 10x + (21})}{10}\text{ = }\frac{62}{5} \\ \frac{33\text{ + 28 + 10x }+\text{ 21}}{10}\text{ = }\frac{62}{5} \\ \frac{82\text{ + 10x}}{10\text{ }}\text{ = }\frac{62}{5} \\ \text{Cross multiply} \\ 5(82\text{ + 10x) = 62 }\times10 \\ 410\text{ + 50x = 620} \\ \text{subtract 830 from both sides} \\ 410\text{ - 410+ 50x = 620 - 4}10 \\ 50x\text{ = 210} \\ \text{Divide both sides by 50} \\ \frac{50x}{50}\text{ = }\frac{210}{50} \\ x\text{ = }\frac{21}{5} \\ x\text{ = 4}\frac{1}{5}\text{ minutes} \end{gathered}\)The next step is to sum all the minutes spent in the relay race
\(\begin{gathered} \text{Total minutes =}\frac{33}{10}\text{ + }\frac{14}{5\text{ }}+\frac{21}{5}+\text{ }\frac{21}{10} \\ \text{Total minutes = }\frac{33\text{ + 28 + 42 + 21}}{10} \\ \text{Total minutes = }\frac{124}{10} \\ \text{Total minutes = 12}\frac{4}{10}\text{minutes} \end{gathered}\)From the above calculations, you will see that the girls ran a total of minutes of 12 4/10 minutes
Therefore, the girls did not break the record

Use substitution to solve the system of
equations: 5x + 5y = -30
2x - y = 15
Answer:
x = 3, y = - 9
Step-by-step explanation:
5x + 5y = - 30...... (1)
2x - y = 15
-y = 15 - 2x
y = 2x - 15..... (2)
From equations (1) & (2)
5x + 5(2x - 15) = - 30
5x + 10x - 75 = - 30
15x = 75 - 30
15x = 45
x = 45/15
x = 3
Plug x = 3 in equation (2)
y = 2*3 - 15
y = 6 - 15
y = - 9
Therefore,
x = 3, y = - 9
or
(x, y) = (3, - 9)

Which is the best estimate of -14 1/9(-2 9/10)?
-42
-28

42
The best estimate of \(-14\frac{1}{9} (-2\frac{9}{10})\) is option (d) 42
The given expression is \(-14\frac{1}{9} (-2\frac{9}{10})\)
First we have to convert the mixed fraction to the simple fraction
Mixed fraction is the a fraction represented with its quotient and remainder
Simple fraction is a fraction having whole numbers for the numerator and denominator.
The estimation is the process of calculating the approximate value of a process or calculation
First term is
\(-14\frac{1}{9}=-\frac{9(14)+1}{9}\)
= -127/9
The second term is \((-2\frac{9}{10})\)
Convert the mixed fraction to the simple fraction
\(-2\frac{9}{10}= -\frac{10(2)+9}{10}\)
= -29/10
Multiply first term and second term
(-127/9)×(-29/10) = 40.92
Hence, the best estimate of \(-14\frac{1}{9} (-2\frac{9}{10})\) is option (d) 42

A batch of lotion was made at a factory by mixing 1.3 liters of ingredient A with 2.7 liters of ingredient B in a mixing vat. By accident, a worker added an extra 0.5 liters of ingredient A to the mixing vat. How many liters of ingredi-ent B should the worker add to the mixing vat so that the ingredients will be in the original ratio
Answer:
The worker needs 3.74L of ingredient B
Step-by-step explanation:
Given
\(A:B = 1.3L:2.7L\)
Required
Determine the B equivalent of (1.3L + 0.5L) of A
\(A:B = 1.3L:2.7L\)
Convert to Fraction
\(\frac{A}{B} = \frac{1.3L}{2.7L}\)
\(\frac{A}{B} = \frac{1.3}{2.7}\) ----(1)
For the new mix of A
\(New\ A = 1.3L + 0.5L\)
\(New\ A = 1.8L\)
New A requires New B:
So:
We have:
\(New\ A: New\ B\)
Convert this to fraction;
\(Ratio = \frac{New\ A}{New\ B}\)
Substitut2 1.8L for New A
\(Ratio = \frac{1.8L}{New\ B}\) --- (2)
Equate (1) and (2)
\(\frac{1.8L}{New\ B} = \frac{1.3}{2.7}\)
Cross Multiply:
\(New\ B * 1.3 = 1.8L * 2.7\)
Divide through by 1.3
\(New\ B = \frac{1.8L * 2.7}{1.3}\)
\(New\ B = \frac{4.86L}{1.3}\)
\(New\ B = 3.74\ L\) (Approximated)
Hence;
The worker needs 3.74L of ingredient B

Answer:
x = 45
Step-by-step explanation:
Because these are two congruent triangles inside of each other we can set up an equivalency ratio.
25/35 = x/65
Multiply both sides by 65 to get x alone
65 * 25/35 = x/65 * 65
(65 * 25)/35 = x1
1576/35 = x
x = 45

Find the volume of the solid whose base is a triangle with vertices (0,0), (0,3), and (5,0). Slices perpendicular to the x-axis are semicircles. Enter answer using exact values.
The volume of the solid whose base is a triangle with vertices (0,0), (0,3), and (5,0) is 25π/12 cubic units.
What is a triangle?
A triangle is a closed geometric shape that is formed by connecting three line segments. These line segments are called sides, and the points where they meet are called vertices. A triangle has three sides, three angles, and three vertices.
To start, let's graph the triangle to get a better understanding of the problem:
(0,3) *
|\
| \
| \
| \
| \
(0,0) *-----*-----> x
(5,0)
The height of this slice is given by the line from the point (x,0) to the point (0,3), which has equation y = 3/5 * x + 0. The radius of the semicircle is half the height of the slice, which is given by the equation r = 3/10 * x.
The area of a semicircle is πr²/2, so the volume of this slice is:
V(x) = π * (3/10 * x)² / 2 * dx
To find the total volume of the solid, we need to integrate this expression over the range of x values that covers the entire base of the solid, which is from x=0 to x=5:
V = ∫₀₅ π * (3/10 * x)² / 2 dx
V = π/20 * ∫₀₅ x² dx
V = π/20 * [x³/3] from 0 to 5
V = π/20 * (5³/3)
V = π/4 * (25/3)
V = 25π/12
Therefore, the volume of the solid is 25π/12 cubic units.

Determine the two equation that represent the following situation:samia paid 15$ for 6 and 3 pens where her brother mohammed paid 9$ for 2 cards and 5 pens.
let x represent the number of cards
and y represent the number of pens
(with steps
Answer: Let's use the given information to set up two equations using x and y as variables:
From the first statement, we know that Samia paid $15 for 6 pens and 3 cards. Let's set up an equation to represent this:
6y + 3x = 15
Similarly, from the second statement, we know that Mohammed paid $9 for 2 cards and 5 pens. Let's set up an equation to represent this:
5y + 2x = 9
So the two equations that represent the situation are:
6y + 3x = 15
5y + 2x = 9
Note that we could have chosen to use different variables, but the important thing is that we use the same variables consistently in each equation.

PLEASE HELP ILL MARK BRAINLIEST
Answer:
a). x = 9
b). m∠ABC = 27°
c). m∠CBD = 153°
Step-by-step explanation:
1). Property of linear pair of angles states, "sum of linear pair of angles is 180°"
3x + (15x + 18) = 180°
18x + 18 = 180
18x = 180 - 18
18x = 162
x = 9
2). m∠ABC = 3x°
= 3×9
= 27°
3). m∠CBD = (15x + 18)°
= (15×9 + 18)°
