A second-grade student is 4 feet tall. Her teacher is 5 2/3 feet tall.
How many times as tall as the student is the teacher?
What fraction of the teacher’s height is the student’s height?
Can anyone help with this please?
Answer:
1. 17/12
2. 12/17
Step-by-step explanation:
The teacher is 1.42 times as tall as the student and the required fraction is given by 17/12
What is a ratio?The quantitative relation between two amounts shows the number of times one value contains or is contained within the other. for example-"the ratio of computers to students is now 2 to 1"
Given here; Height of the student = 4 ft. and height of teacher =5²/₃
Ratio of the height of the teacher and student is
= 5+2/3 / 4 ( 5²/₃=5+2/3 , property of mixed fractions)
= 17/3 × 1/4
=17/12
=1.4166
Thus we can say that the height of teacher is 1.42 times as tall as the student.
Also as given above the teacher's height is 17/12 the students height.
Hence, The teacher is 1.42 times as tall as the student and the required fraction is given by 17/12

Write the equation of a circle with a center at (-2,-10) and a radius of 1.2.
A) (x + 2)2 + (y + 10)2 =1.2
B) (x - 2)2 + (y - 10)2 = 1.2
C) (x + 2)2 + (y + 10)2 = 1.44
D) (x + 2)2 + (y + 10)2 = 14.4
Answer:
The correct option is the letter "C", [tex](x + 2)^2 + (y + 10)^2 = 1.44[/tex].
Step-by-step explanation:
The standard form for a circle's equation has the following structure:
[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]
Where [tex](x_c,y_c)[/tex] are the coordinates of the center of the circle and [tex]r[/tex] is the radius. Applying the data from the problem we have:
[tex](x - x_c)^2 + (y - y_c)^2 = r^2\\\[[x - (-2)]^2+ [y - (-10)]^2 = (1.2)^2\\(x + 2)^2 + (y + 10)^2 = 1.44[/tex]
Therefore the correct answer is the letter "C", [tex](x + 2)^2 + (y + 10)^2 = 1.44[/tex].

The side length of a square is 5.25 inches. What is its area? What is its perimeter? Be sure to show your work for credit and don't forget to label units!
Answer:
Step-by-step explanation:
area of a square is just L^2 or one of the sides squared
and the perimeter is 4L
that means
Area = 5.25^2
= 27.5625 in^2
Perimeter = 4 * 5.25
= 21 in
What is the equation of the line that has a slope of –4 and passes through the point (2, 3)?
Answer:
y=-4x+11
Step-by-step explanation:
We can use the point-slope form of a line to solve this, which is
y - y₁ = m (x - x₁), where (x₁ , y₁) is a point and m is the slope.
We have:
y - 3 = -4(x - 2)
y - 3 = -4x + 8
y = -4x + 11

A cone with a radius of 7ft and a height of 12ft is filled with wet sand. you took that sand and built a pyramid with a base of 4ft by 5ft how tall would the resulting pyramid be?
Answer:
95.36 ft
Step-by-step explanation:
Volume of a Cone[tex]=\frac{1}{3}\pi r^2 h[/tex]
Radius=7 ft, Height=12 ft
Therefore the volume of sand in the cone
[tex]=\frac{1}{3}\pi *7^2*12\\=615.7522$ ft^2[/tex]
If the sand was used to build as pyramid with a base of 4ft by 5ft.
Volume of a Pyramid[tex]=\frac{1}{3}*$Base Area* Height[/tex]
[tex]615.7522=\frac{1}{3}*(4*5)* Height\\615.7522=\dfrac{20}{3}* Height\\$Multiply both sides by \dfrac{3}{20}\\$Height =615.7522*\dfrac{3}{20}\\\\$Height of the pyramid=95.36 ft[/tex]

Write one digit on each side of 92 to make a four digit multiple of 45. How many different solutions does this problem have?
(___92___)
Please help me!! I will give brainliest!!!!
Answer:
7920, 2925
Step-by-step explanation:
The four-digit number has to be a multiple of 5 and also a multiple of 9. So, the last number is either a 0 or a 5, and the addition of the 4 digits must be equal to 9, 18, 27, et cetera, like every multiple of 9.
For the case: _920, the addition of digits gives 11, then the only possible first digit is 18-11 = 7
For the case: _925, the addition of digits gives 16, then the only possible first digit is 18-16 = 2

7(2 - x) = 28.
Answer:
x = -2
Step-by-step explanation:
7(2 - x) = 28
Distribute
14 -7x = 28
Subtract 14 from each side
14-7x-14 = 28-14
-7x = 14
Divide each side by -7
-7x/-7 = 14/-7
x = -2

Answer:
dy/dx = d/dx sin(x-3/x+2)
dy/dx = cos(x-3/x+2) . d/dx (x-3/x+2)
dy/dx = cos(x-3/x+2) . (x + 2 - x + 3)/(x+2)²
dy/dx = [5cos(x-3/x+2)]/(x + 2)²

What is slope intercept formula. Best answer brainliest
Answer:
y= mx+b
Step-by-step explanation:
Slope intercept formula:
y=mx+b
m= slope
b= y intercept
Answer:
The equation of a horizontal line is y = b where b is the y-intercept. Since the slope of a horizontal line is 0, the general formula for the standard form equation , y = mx + b becomes y = 0x +b y = b. Also,since the line is horizontal, every point on that line has the exact same y value. This y-value is therefore also the y-intercept.

Find the QUADRATIc equation 100 POINTS PLS HELP (1,6),(2,19),(3,38),(4,63),(5,94)
Answer:
[tex] \displaystyle 3 {x}^{2} + 4x - 1 = 0[/tex]
Step-by-step explanation:
we are given some coordinates
(1,6),(2,19),(3,38),(4,63),(5,94)
we want to figure out the quadratic equation which passes those coordinates
notice that, the coordinates in quadratic sequence
we know that,
A sequence is quadratic if and only if it has second difference
recall that,
[tex]\displaystyle 2a=2^{ \text{nd }} \text{diff}[/tex][tex] \displaystyle 3a + b = U_{2}-U_1[/tex][tex] \displaystyle a + b + c = U_1[/tex]these formulas are necessary to figure out a,b and c
because we know that
Quadratic equation standard form:
[tex] \displaystyle a {x}^{2} + bx + c = 0[/tex]
therefore to figure out a,b and c these formulas are important
let's figure out a:
we got that 2nd difference is 6 thus
[tex] \displaystyle 2a = 6[/tex]
divide both sides by 2
[tex] \displaystyle \frac{2a}{2} =\frac{ 6}{2}[/tex]
[tex] \displaystyle a = 3[/tex]
let's figure out b:
by using the second formula we can figure out b
our [tex]U_1[/tex] and [tex]U_2[/tex] are 6 and 19 respectively
substitute:
[tex] 3 \cdot 3 + b = 19 - 6[/tex]
simplify multiplication:
[tex]9+ b = 19 - 6[/tex]
simplify substraction:
[tex]9+ b = 13[/tex]
cancel 9 from both sides:
[tex]b = 4[/tex]
let's figure out c:
our [tex]U_1[/tex] is 6
substitute:
[tex] \displaystyle 3 + 4 + c = 6[/tex]
simplify addition:
[tex] \displaystyle 7 + c = 6[/tex]
cancel 7 from both sides:
[tex] \displaystyle c = - 1[/tex]
altogether substitute a,b and c to quadratic equation:
[tex] \displaystyle 3 {x}^{2} + 4x - 1 = 0[/tex]
and we are done!
