Answer:
60 textbooks
Step-by-step explanation:
1) 56*15:14=60
Answer:
60 textbooks
Step-by-step explanation:
To get the answer, you have to divide 56 by 14/15. What I'd do is id think of 56
as 56/1. I'd change 14/15 into a multiplicative inverse/reciprocal, ending up with 15/14. From there, id multiply 56/1 and 15/14, ending up with 840/14.Using long division, id do 840 divided by 14, ending up with 60.

A variable cubed A) b ÷ 3
Quotient of some number and three B) z + 3
Product of an unknown value and three C) x3
Three less than a variable D) y − 3
Three more than some number E) 3a
Answer:
3 more than a number, z+3
three less than a variable, y-3
product of an unknown value and 3, 3a
quotient of some number and 3, b ÷ 3
and i think x3 is the cubed but it would be written as x^3

A model of an Egyptian pyramid has a slant height of 18 centimeters and a 15-centimeter square base. What is the surface area of the pyramid?
PLZ ANSWER QUICKLY AND ACCURATELY WILL MARK BRAINLIEST
Answer:
here is an example to guide you
Step-by-step explanation:
To find how much paper for the model, you will use the formula for area of a square and area of a triangle.
A = bh
7.2 x 7.2
A = 51.84 cm²
A = 1/2bh
1/2 x 7.2 x 6
A = 21.6 cm²
21.6 cm² x 4 = 86.4 cm²
86.4 + 51.86=138.3
You will need 138.3 cm² of paper.

Where do the slope and y-intercept show up in the tables and graphs?
Answer:
Solution: The general form of the line on a graph is y = mx+c,
where y is the coordinate of the point along the y-axis,
x is the coordinate of the point along the x-axis,
m is the slope of the line or arc tan of the angle the line makes with the x-axis, and
c is the intercept the line makes on the y-axis.
Suppose we want a line having a slope of 45º with the x-axis and passes through point P (4,6), the equation of the line is
y = mx + c
6 = tan 45 * 4 + c, or
6 = 4 + c, or
c = 6–4 = 2.

Answer:
y intercept : if jada doesn't sell anything, she loses $250
Pos/neg interval: jada needs to sell more than 35 kilos in order to make a profit
Increase/decrease interval: the more paprika she sells, the more profit she makes
Step-by-step explanation:
y intercept is when she sells 0 kilos and is at -250 on the y axis
pos/neg interval is whether or not she is above or below 0 on the x axis (she has to be above it in order to make a profit)
The more the line is increasing, the larger profit she makes

Solve each of the following equations
1-|3p+1|=-3
Answer:
p=1 p = -5/3
Step-by-step explanation:
1-|3p+1|=-3
Subtract 1 from each side
1-|3p+1| -1=-3-1
-|3p+1|=-4
Divide by -1
|3p+1|=4
The absolute value has two solutions one positive and one negative
3p+1 = 4 3p+1 = -4
Subtract 1 from each side
3p+1-1 = 4-1 3p+1-1 = -4-1
3p = 3 3p = -5
Divide by 3
3p/3 = 3/3 3p/3 = -5/3
p=1 p = -5/3
Answer:
p=-5/3,1
Step-by-step explanation:
Subtract 11 from both sides.
-|3p+1|=-3-1
−∣3p+1∣=−3−1
2 Simplify -3-1−3−1 to -4−4.
-|3p+1|=-4
−∣3p+1∣=−4
3 Multiply both sides by -1−1.
|3p+1|=4
∣3p+1∣=4
4 Break down the problem into these 2 equations.
3p+1=4
3p+1=4
-(3p+1)=4
−(3p+1)=4
5 Solve the 1st equation: 3p+1=43p+1=4.
p=1
p=1
6 Solve the 2nd equation: -(3p+1)=4−(3p+1)=4.

The volume of this prism is cubic inches.
Answer:
140
Step-by-step explanation:
The prism shown is a rectangular prism
Volume of a rectangular prism = length * width * height
Given length: 3 1/2
Given width: 5
Given height: 8
Volume = 3.5 * 5 * 8 = 140
Answer:
[tex]A=140[/tex]
Step-by-step explanation:
The volume of a three-dimensional object is the amount of space the object takes up. In this case, the prism is a rectangular prism, its volume can be found using the following formula,
[tex]A=l*w*h[/tex]
Substitute the given values into this formula,
[tex]A=l*w*h[/tex]
[tex]A=8*5*3\frac{1}{2}[/tex]
Simplify,
[tex]A=8*5*3\frac{1}{2}[/tex]
[tex]A=40*3\frac{1}{2}[/tex]
Convert the mixed number into an improper fraction, this can be done by multiplying the "number" part of the mixed number by the denominator (number under the fraction bar). Then one adds the result to the numerator (number over the fraction bar).
[tex]A=40*3\frac{1}{2}[/tex]
[tex]A=40*\frac{(3*2)+1}{2}[/tex]
[tex]A=40*\frac{6+1}{2}[/tex]
[tex]A=40*\frac{7}{2}[/tex]
To simplify further, one must divide the number the fraction is being multiplied by the denominator of the fraction,
[tex]A=40*\frac{7}{2}[/tex]
[tex]A=20*7[/tex]
Multiply to finish simplifying and get the answer,
[tex]A=20*7[/tex]
[tex]A=140[/tex]

the diagonal of a square has a length of 10. what is the area of the square?
Answer:
50
Step-by-step explanation:
Diagonal of square = 10
Use special triangles to find the area because a square's diagonal divides the 90 degree angles into 45 degrees
45-45-90 triangle
x : x : x√2
1 : 1 : 10
10=x√2
10/√2=x, rationalize denominator and you get 5√2 as the square's side length
Area is s^2, s being the length of a side
(5√2)^2=25*2=50

Help me pleaseeeeeee
Answer:
B
it's a recurring number therefore it's irrational
Functions, f and g are given by f(x)= 3+ cos x and g(x) = 2x, x is a real number. Determine the value of c for which f(g(x))= g(f(x)) where 0[tex]\leq[/tex]x<2[tex]\pi[/tex]
The value x is equal to [tex]\pi[/tex] for which f(g(x))=g(f(x))
Given :
f(x)=3+cos(x)
g(x)=2x
To find : the value of x over the given interval [tex]0\leq x\leq 2\pi[/tex]
Apply composition of functions. Replace g(x) inside f(x) to find f(g(x))
[tex]f(g(x))=f(2x)=3+cos(2x)\\g(f(x))=g(3+cosx)=2(3+cosx)\\[/tex]
Now we set f(g(x))=g(f(x)) and solve for x
[tex]3+cos(2x)=2(3+cosx)\\3+cos(2x)=6+2cos(x)\\\cos \left(2x\right)-2\cos \left(x\right)-3=0\\\\we \; know:\ cos(2x)=2cos^2(x)-1\\-4-2\cos \left(x\right)+2\cos ^2\left(x\right)=0\\2cos^2(x)-2cos(x)-4=0\\\\divide \; by \; 2 \; and \; Factor \; left \; hand \; side\\\\cos^2(x)-cos(x)-2=0\\\\(cosx-2)(cosx+1)=0\\\cos \left(x\right)=2,\:\cos \left(x\right)=-1[/tex]
cos(x)=2 cannot be solved , so no solution
[tex]cos(x)=-1\\cos is -1 at x=180 degree\\So , x=\pi[/tex]
