Answer:
A - 90ml
B - 150ml
Step-by-step explanation:
A - 150ml ÷ 100 = 1.5 x 60 = 90ml
B - 250ml ÷ 100 = 2.5 x 60 = 150ml
Brandon needs 90 ml and 150 ml of alcohol to make 150 ml and 250 ml hand sanitizer.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Brandon decided to make his own hand sanitizer.
To be effective, hand sanitizer should contain 60% alcohol.
a) 150ml of hand sanitizer;
Use percentage formula,
Percentage of alcohol = 150 x 60 / 100
Percentage of alcohol = 90 ml
a) 250ml of hand sanitizer;
Use percentage formula,
Percentage of alcohol = 250 x 60 / 100
Percentage of alcohol = 150 ml
Therefore, he needs 90 ml and 150 ml of alcohol to make 150 ml and 250 ml hand sanitizer.

2. In the product of (4a3 + 5a2 – 11a) and (-15 + 3a – 7a2), the co-efficient of a4 is …………………… .
Answer:
- 23
Step-by-step explanation:
We could do this the long way and expand the whole product or note that the [tex]a^{4}[/tex] terms arise from the product of the a³ and a terms and the product of the a² and a² terms, that is
4a³ × 3a = 12[tex]a^{4}[/tex]
+ 5a² × - 7a² = - 35[tex]a^{4}[/tex]
Summing gives
12[tex]a^{4}[/tex] - 35[tex]a^{4}[/tex] = - 23[tex]a^{4}[/tex]
with coefficient - 23
The only pairs that will give you some multiple of [tex]a^4[/tex] are:
[tex]4a^3\cdot (3a),\quad 5a^2\cdot(-7a^2)[/tex]
their values are respectively

During a scuba dive, Lainey descended to a point 26 feet below the ocean surface. She continued her descent at a rate of 26 feet per minute. Enter an inequality you could solve to find the number of minutes she can continue to descend if she does not want to reach a point more than 78 feet below the ocean surface. Use t to represent the variable for the minutes Lainey can continue to descend.
Answer:
t ≤ 2
Step-by-step explanation:
Given that:
Initial Position = - 26 feets (below surface)
Descent rate = 26 feets per minute
Maximum depth = 78 feets
Let t = number of minutes
Hence,
Initial position + (descent rate * number of minutes) ≤ - 78
-26 + (- 26t) ≤ - 78
-26t ≤ - 78 + 26
-26t ≤ - 52
t ≤ 52/26
t ≤ 2

Consider the function f(x) = 3x - 2 and the function g(x), which is represented by the table below. Which of the following statements about f(x) and g(x) is true? Select all that apply.
1. The slope of f(x) is smaller than the slope of g(x)
2. The lines represented by f(x) and g(x) are parallel.
3. The line represented by f(x) crosses the x-axis to the right of the line represented by g(x).
4. The y-intercept of f(x) is smaller than the y-intercept of g(x).
5. The values of f(x) and g(x) are the same at x = 3
Answer:
4. 5. 3. are correct im pretty sure
Step-by-step explanation:
Statements 1, 2, and 3 about f(x) and g(x) are "true".
What are the functions?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
Consider the function f(x) = 3x - 2 and the function g(x), which is represented by the table below.
x : 1 3 5 7 9
g(x): 3 7 11 15 19
Here the slope of the function g(x) is 2.
This means statements 1 and 2 are false because slopes are different.
To compare the position of the lines at the x-axis, you can evaluate the function at x=0. f(0) = 3×0 - 2 = -2 and g(0) = -1.
Since g(0) is less than f(0), the line represented by g(x) crosses the x-axis to the right of the line represented by f(x). So, statement 3 is true.
The y-intercept of f(x) is -2, while the y-intercept of g(x) is 1. So, statement 4 is true.
To compare the values of f(x) and g(x) at x=3, you can evaluate the functions at x=3. f(3) = 3×3 - 2 = 7 and g(3) = 7. So, the values of f(x) and g(x) are the same at x=3. So, statement 5 is true.
Therefore, the true statements are 2, 3, and 4.

Answer:
The answer is A
Step-by-step explanation:
The correct answer is:
A) If a line divides two sides of a triangle proportionally, then it is
parallel to the third.
What is triangle proportionally?If a line is drawn parallel to any one side of a triangle so that it intersects the other two sides in two distinct points, then the other two sides of the triangle are divided in the same ratio.
The converse of the triangle proportionality theorem states "If a line divides two sides of a triangle proportionally, then that line is parallel to the third side."
Hence, the converse will be If a line divides two sides of a triangle proportionally, then it is parallel to the third.

A new neighborhood activity complex is being built in Erie. The perimeter of the rectangular playing field is 448 yards. The length of the field is 6 yards less than quadruple the width. What are the dimensions of the playing field?
Answer:
Length = 178 yards and Breadth = 46 yards
Step-by-step explanation:
The perimeter of the rectangular field is 448 yards
Let the width is b and the length of the field is (4b-6) yards
We need to find the dimensions of the playing field. We know that the perimeter of a rectangle is given by :
P = 2(l+b)
ATQ,
[2((4b-6)+b)] = 448
2(5b-6) = 448
5b-6 = 224
5b = 230
b = 46 yards
Length = (4b-6)
= 4(46) - 6
= 178 yards
Hence, the length and breadth of the field is 178 yards and 46 yards respectively.

Step-by-step explanation:
The cost for boarding is $18 each day. The cost for play-time is $6.75 each day. So, the charges for both add up to ...
$18 +6.75 = $24.75
each day.
The manners lesson is a flat fee added to the daily boarding charges, so for d days, the total bill is ...
$24.75·d +45.99 = 417.24 . . . . . equation relating days to cost
We solve this 2-step equation by first subtracting the constant on the left.
$24.75·d = $371.25
Then we divide by the coefficient of the variable:
d = $371.25/$24.75
d = 15

On a coordinate plane, trapezoids A B D C and M N P Q are shown. The length of A B is 4 units and the length of B D is 2 units. The length of M N is 10 units and the length of N P is 6 units.
Is trapezoid ABDC the result of a dilation of trapezoid MNPQ by a scale factor of Two-fifths? Why or why not?
Yes, because AB and CD are each Two-fifths the lengths MN and QP.
Yes, because sides AB and CD are parallel to sides MN and QP.
No, because AB is Two-fifths the length MN but CD is One-third the length QP.
No, because sides AB and CD have different slopes from sides MN and QP.
9514 1404 393
Answer:
C. No, because AB is Two-fifths the length MN but CD is One-third the length QP.
Step-by-step explanation:
Dilation multiplies each coordinate or length by the scale factor. Here, different corresponding lengths are multiplied by different values, so no dilation is involved.
__
Additional comment
Dilation shouldn't change any slopes, so if slopes of corresponding segments are different, that is another indication dilation is not involved. (No figure is supplied here, so we cannot judge slopes.)

Agustín fabrica artículos de cuero y los vende con un incremento del 8% de su costo. Si en su última campaña utilizó un cuero de mayor calidad y aplicó un incremento adicional de 12%, ¿cuál fue el aumento único equivalente del precio?
Answer:
El aumento del precio de costo único equivalente es un aumento del 20,96% en el precio de costo
Step-by-step explanation:
Los parámetros dados son;
El porcentaje de aumento en el precio de costo que Augustin vende artículos de cuero = 8%
El aumento adicional de Augustin se aplica cuando usó cuero de mayor calidad = 12%
Sea x el precio de costo
Tenemos, el primer precio de venta = 1.08 × x
El precio de venta del cuero de alta calidad = 12% adicional al precio de venta anterior
∴ El precio de venta del cuero de alta calidad = 1,12 × 1,08 × x = 1,2096 × x
Por lo tanto, el precio de venta del cuero de alta calidad = (1.2096 × 100)% de x = 120.96% de x, lo que da;
El aumento del precio de costo único equivalente = (120,96% - 100%) aumento en x = 20,96%
∴ El aumento del precio de costo único equivalente = 20,96% de aumento en el precio de costo.
