SELECT MUTIPLE CHOICE !
Answers
Answer:
12.5 m
17.5 m
20 m
Step-by-step explanation:
Scale of the drawing to the actual size of the field = 24 mm : 5 m
✍️Given an actual length of 96 mm, actual length would be x m.
Thus:
24 mm : 5 m = 96 mm : x m
[tex] \frac{24}{5} = \frac{96}{x} [/tex]
Cross multiply
[tex] 24x = 96*5 [/tex]
[tex] 24x = 480 [/tex]
Divide both sides by 24
[tex] x = \frac{480}{24} [/tex]
✅[tex] x = 20 m [/tex]
✍️Given an actual length of 84 mm, actual length would be x m.
Thus:
24 mm : 5 m = 84 mm : x m
[tex] \frac{24}{5} = \frac{84}{x} [/tex]
Cross multiply
[tex] 24x = 84*5 [/tex]
[tex] 24x = 420 [/tex]
Divide both sides by 24
[tex] x = \frac{420}{24} [/tex]
✅[tex] x = 17.5 m [/tex]
✍️Given an actual length of 60 mm, actual length would be x m.
Thus:
24 mm : 5 m = 60 mm : x m
[tex] \frac{24}{5} = \frac{60}{x} [/tex]
Cross multiply
[tex] 24x = 60*5 [/tex]
[tex] 24x = 300 [/tex]
Divide both sides by 24
[tex] x = \frac{300}{24} [/tex]
✅[tex] x = 12.5 m [/tex]

Answers

3.78 because u subtract 17.22 from 21
Answer: Please make your question clearer next time.
n= 3.78
Step-by-step Explanation:
Subtract 17.22 from both sides of the equation.
n + 17.22=22
n + 17.22 - 17.22 = 21 - 17.22
Simplify: 21 - 17.22= 3.78, Therefore n= 3.78.

C) y = (x + 1)^2 - 1
D) y = (x + 1)^2
Answers
Answer:
D) y = (x+1)^2
Step-by-step explanation:
Given the graph, the y-intercept is 1, and the x-intercept is -1. Only equation that works is D:
When we plug in x=-1:
y=(-1+1)^2
y=0
This is shown on the graph
When we plug in y=1:
1=(x+1)^2
1=x+1

At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of silk and cotton fabrics for a dress. Silk is $16.90 per yard and cotton is $4 per yard. Write an equation that represents the total yards of fabric.
Answers
Answer:
Answer:
Silk = x = 1.5 yards
Cotton = y = 2.75 yards
Step-by-step explanation:
x + y = 4.25
16.90x + 4y = 36.35
1. The solution to the equation represent number of yards of silk and number of yards of cotton bought.
2.
x + y = 4.25 (1)
16.90x + 4y = 36.35 (2)
Multiply (1) by 4
4x + 4y = 17 (3)
16.90x + 4y = 36.35 (2)
Subtract (3) from (2)
16.90x - 4x = 36.35 - 17
12.90x = 19.35
Divide both sides by 12.90
x = 19.35 / 12.90
= 1.5
x = 1.5 yards
Substitute x = 1.5 yards into (1)
x + y = 4.25
1.5 + y = 4.25
y = 4.25 - 1.5
= 2.75
y = 2.75 yards
Silk = x = 1.5 yards
Cotton = y = 2.75 yards

Answer:
13) 23/4 14) 13/2 15) 6 1/2 16) 2 7/12
Step-by-step explanation:
13) (4 x 5) + 3 = 23 -> 23/4
14) (2 x 6) + 1 = 13 -> 13/2
15) 13/2 = 6.5, then take the number on the left of the decimal so, 6, as your whole number. After that, multiply it by the denominator so 6 x 2 = 12, then subtract the 12 with the numerator given in the improper fraction so, 13-12 = 1. The answer you get (which is 1 in this case) will be your numerator in for the mixed fraction. -> 6 1/2
Note: the denominator always stays the same
16) 31/12 = 2.58... take the 2 as your whole number.
2(whole number) x 12(denominator) = 24
31 - 24 = 7
= 2 7/12

the vertices of a triangle are located at (-3,-1), (2,3),(5,2). record the triangles perimeter to the nearest whole number
Answers
Answer:
The perimeter of the triangle is approximately equal to 18
Step-by-step explanation:
The coordinates of the vertices of the triangle are (-3, -1), (2, 3), and (5, 2)
The formula for the lengths, l, of the sides of the triangle, given their end points coordinates is presented as follows;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
The lengths of the segments that make up the triangle are therefore;
Between the vertex points (-3, -1) and (2, 3), we have, √((-3 - 2)² + (-1 - 3)²) = √41
Between the vertex points (-3, -1) and (5, 2), we have, √((-3 - 5)² + (-1 - 2)²) = √73
Between the vertex points (2, 3) and (5, 2), we have, √((2 - 5)² + (3 - 2)²) = √10
Therefore;
The perimeter of the triangle = The sum of the lengths of the sides of the triangle = √41 + √73 + √10
The perimeter of the triangle = √41 + √73 + √10 ≈ 18.1094
∴ The perimeter of the triangle ≈ 18, after rounding to the nearest whole number.

[tex]\displaystyle y =\frac{1}{2}x+5[/tex]
Step-by-step explanation:
Equation of the line
The slope-intercept form of a line is given by:
[tex]y=mx+b[/tex]
Being:
m = the slope of the line
b = the y-intercept
We can also use the point-slope form of the line:
[tex]y - k=m(x-h)[/tex]
Being:
(h,k) = A point that belongs to the line
Two lines of slopes m1 and m2 are perpendicular if:
[tex]m_1.m_2=-1[/tex]
We are given the line:
[tex]y=-2x+5[/tex]
Whose slope is m1=-2
Thus, the perpendicular line has a slope of:
[tex]\displaystyle m_2=-\frac{1}{m_1}[/tex]
[tex]\displaystyle m_2=-\frac{1}{-2}[/tex]
[tex]\displaystyle m_2=\frac{1}{2}[/tex]
The required line contains the point (-8,1), thus the equation is:
[tex]\displaystyle y - 1=\frac{1}{2}(x+8)[/tex]
Removing the parentheses:
[tex]\displaystyle y - 1=\frac{1}{2}x+\frac{1}{2}\cdot 8[/tex]
Adding 1:
[tex]\displaystyle y =\frac{1}{2}x+\frac{1}{2}\cdot 8+1[/tex]
Operating:
[tex]\displaystyle y =\frac{1}{2}x+4+1[/tex]
[tex]\mathbf{\displaystyle y =\frac{1}{2}x+5}[/tex]

What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
The given statement is “two less than the quotient of a number cubed and sixteen, increased by eight”
"Two less than x" describes "x- 2"
"Quotient of x and y" describes x/y
"x increased by y" describes x+y
n³/16 is the quotient and 2 is subtracted and 8 is increased which means 8 is added.
So, the expression is n³/16-2+8
= n³/16 +6
When n=4, we get
4³/16 +6
= 4+6
= 10
Therefore, the options A and H are correct answer.

Clara is taking a medicine for a common cold. The table below shows the amount of medicine f(t), in mg, that was present in Clara's body after time t:
t (hours) 1 2 3 4 5
f(t) (mg) 236.5 223.73 211.65 200.22 189.41
Heidi was administered 300 mg of the same medicine. The amount of medicine in her body f(t) after time t is shown by the equation below:
f(t) = 300(0.946)t
Which statement best describes the rate at which Clara's and Heidi's bodies eliminated the medicine?
A) Clara's body eliminated the antibiotic faster than Heidi's body.
B) Clara's body eliminated the antibiotic at the same rate as Heidi's body.
C) Clara's body eliminated the antibiotic at half of the rate at which Heidi's body eliminated the antibiotic.
D) Clara's body eliminated the antibiotic at one-fourth of the rate at which Heidi's body eliminated the antibiotic.
Answers
Answer: Clara's body eliminated the antibiotic at the same rate as Heidi's body.
Step-by-step explanation:
1) Let's write the data of Clara's table just to have them ready to compare
t (hours) 1 2 3 4 5
f(t) (mg) 236.5 223.73 211.65 200.22 189.41
Change(mg) - -12.77 -12.05 -11.43 -10.81
2) Now calculate the amount of medicine as per Heide's formula, 300(0.946)^t:
t (hours) 1 2 3 4 5
f(t) (mg) 283.8 268.48 253.98 240.26 227.29
Change (mg) -15.12 -14.5 -13.72 -12.97
Now you can compare the data and realize that the rate of change of Heide is greater than the rate of change of Clara, meaning that Heide eliminates the medicine faster than Clara.
