Answer:
23 packages
Step-by-step explanation:
To find the number of [tex]\frac{3}{4}[/tex] pound packages that can be made from [tex]17\frac{1}{4}[/tex] pounds, we simply divide [tex]17\frac{1}{4}[/tex] by [tex]\frac{3}{4}[/tex].
[tex]\frac{17\frac{1}{4} }{\frac{3}{4} }[/tex]
=> [tex]\frac{\frac{69}{4} }{\frac{3}{4} }[/tex] = [tex]\frac{69}{4} * \frac{4}{3}[/tex] = 23

Only find total surface area and volume.
Answer:
see explanation
Step-by-step explanation:
The triangular prism has 3 rectangular faces and 2 congruent triangular faces.
rectangular base CDEF = 8 × 2 = 16 cm²
rectangular side ABFE = 6 × 2 = 12 cm²
sloping rectangle ABCD = 10 × 2 = 20 cm²
2 triangular faces = 2 × [tex]\frac{1}{2}[/tex] × 8 × 6 = 48 cm²
Total surface area = 16 + 12 + 20 + 48 = 96 cm²
----------------------------------------------------------------------
The volume (V) of the prism is calculated as
V = Bh ( B is the area of triangular face and h the depth of the prism )
B = [tex]\frac{1}{2}[/tex] × 8 × 6 = 24 cm² and h = 2 cm
V = 24 × 2 = 48 cm³

This question is incomplete because it lacks the appropriate diagram.
Please find attached to this answer , the appropriate diagram
Answer:
First option tan x° = 8 ÷6
Step-by-step explanation:
When we solve for angles in a right angled triangle or we are trying to find one if the sides of a right angled triangle, we used trigonometric functions to find our answers. These trigonometric functions include Sine (sin) , Cosine (cos) and Tangent (tan)
Tangent also called short form tan is used when solving problems involving a right angled triangle.
A right angled triangle has 3 sides, the Hypotenuse, the opposite side and the adjacent side.
When we are asked to find the tangent of an angle,
tan = Opposite side / Adjacent side
In the question above, we are asked to find tan x° where x is the angle.
The opposite side = 8cm
The adjacent side = 6cm
Therefore, tan x° = 8cm/6cm = 8cm ÷ 6cm

f(x) = 2x^2 – 5x; find f(3)
Answer:
f(3) = 3
Step-by-step explanation:
f(x) = 2x^2 – 5x
Let x = 3
f(3) = 2(3)^2 - 5(3)
= 2*9 -15
= 18-15
=3
Answer:
f(3)=3
Step-by-step explanation:
This question asks us to find f(3). We want to find what f(x), or y is, when x is equal to 3.
f(x)=2x^2-5x
Substitute 3 in for x.
f(3)=2(3)^2-5(3)
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
Evaluate the exponent first. 3^2 is the same as 3*3, which is equal to 9.
f(3)=2(9)-5(3)
Multiply 2 and 9
f(3)=18-5(3)
Multiply 5 and 3
f(3)=18-15
Subtract 15 from 18
f(3)=3

Create an equation with one solution of x = −7.
10x − (x − 2) = 2x − (_+ x)
Full question is on attached image. All help is appreciated :)
Answer:
10x − (x − 2) = 2x − (40 + x).
The missing number is 40.
Step-by-step explanation:
Let the missing number be a, Then:
10x - (x - 2) = 2x - (a + x)
10x - x + 2 = 2x - a + x
9x - 2x - x = -a - 2
6x = -a - 2
When x = -7:
6(-7) = - a - 2
-42 + 2 = -a
-40 = -a
a = 40.
So the equation is
10x − (x − 2) = 2x − (40 + x).

The common denominator is 48

5/48
Answer:
2a) [tex]1\frac{7}{16}[/tex]
2b) [tex]\frac{5}{48}[/tex]
Step-by-step explanation:
The first thing we need to do is add all the fractions together so,
2a) [tex]2\frac{1}{2} +3\frac{3}{16}+\frac{7}{8}[/tex]
We need to find the LCM of the denominators in order to properly add the fractions together so the LCM is 16
[tex]2\frac{1}{2} +3\frac{3}{16}+\frac{7}{8}[/tex] = [tex]2\frac{8}{16} +3\frac{3}{16} +\frac{14}{16} = 5\frac{25}{16} =6\frac{9}{16}[/tex]
Now we subtract this from 8 as asked in the question,
[tex]8-6\frac{9}{16} =\frac{8}{1} -\frac{105}{16} =\frac{128}{16} -\frac{105}{16}=\frac{23}{16} =1\frac{7}{16}[/tex]
2b) We are asked to minus the fraction [tex]1\frac{7}{16}[/tex] from [tex]1\frac{1}{3}[/tex]
Find the common denominator which is 48
[tex]1\frac{7}{16} -1\frac{1}{3} =1\frac{21}{48} -1\frac{16}{48} =\frac{5}{48}[/tex]
A sphere has a radius of 5 inches. What is its volume? Sphere V = 4 3 πr3 1. Substitute the radius into the formula: V = 4 3 π(53) 2. Evaluate the power: V = 4 3 π(125) 3. Simplify: V = in.3
Answer:
The volume of sphere is 524 in³ .
Step-by-step explanation:
By substituing the radius into the formula :
[tex]v = \frac{4}{3} \times \pi \times {r}^{3} [/tex]
Let r = 5,
[tex]v = \frac{4}{3} \times \pi \times {5}^{3} [/tex]
[tex]v = \frac{4}{3} \times \pi \times 125[/tex]

How many real roots does the following equation have?
x4 -81 = 0
Answer:
Find roots of x4−81=0 by solving for x. x=3,−3
Step-by-step explanation:
The given equation [tex]x^4[/tex] - 81 = 0 has a total of two real roots x = 3 and
x = -3.
We have,
The given equation [tex]x^4[/tex] - 81 = 0 can be factored as a difference of squares:
[tex](x^2)^2 - 9^2 = 0\\(x^2 - 9)(x^2 + 9) = 0[/tex]
Further simplifying:
(x - 3)(x + 3)(x² + 9) = 0
From this factorization, the equation has two linear factors (x - 3) and
(x + 3) and one quadratic factor (x² + 9).
The linear factors, (x - 3) and (x + 3), will each provide one real root since they are linear equations.
x = 3 and x = -3.
The quadratic factor (x² + 9) has no real roots.
This is because the discriminant (b² - 4ac) of the quadratic equation is negative (a = 1, b = 0, c = 9), indicating that there are no real solutions.
Therefore,
The given equation [tex]x^4[/tex] - 81 = 0 has a total of two real roots,
x = 3 and x = -3.

$3,000 is invested in an account that earns 3% annually interest, compounded monthly.
What is the value of the account after 10 years ?
Given the principal and annual interest rate, the total amount accrued after 10 years is approximately $4,048.06.
The compound interest formula is expressed mathematically as;
A = P(1 + r/n)^(n*t)
Where A is amount accrued, P is principal, r is interest rate, n is number of times interest applied per time period and t is time.
Given the data in the question;
Principal P = $3,000Annual interest rate r = 3% = 3/100 = 0.03Compounded monthly n = 12Time t = 10 yearsPlug the given values into the formula above and solve for A.
A = P(1 + r/n)^(n*t)
A = 3000(1 + 0.03/12)^(12 × 10)
A = 3000(1 + 0.0025 )¹²⁰
A = 3000(1.0025 )¹²⁰
A = 3000( 1.34935354 )
A = $4,048.06
Given the principal and annual interest rate, the total amount accrued after 10 years is approximately $4,048.06.

Pilar built a tower by stacking identical layers on top of each other. If her tower used a total of 312 blocks and if the bottom layer has 13 blocks, how tall is her tower? Explain how you know.
Answer:
The height of the tower = 24 units.
Explanation:
In the question above, we are given the following variables.
The total number of blocks used = 312 blocks
The bottom layer( base of the tower) = 13 blocks
We are to find how tall the tower is = height of the tower = unknown.
The total number of blocks used = Volume of the tower = 312 cubic units(blocks)
Area of the base = number of the blocks used in the bottoms layer = 13 square units( block).
Because blocks are used, we assume that this is a Rectangular based prism
The Volume of a Rectangular based prism = Area of the base × h
312 = 13 × h
h = 312 cubic units ÷ 13 square units.
h = 24 units.
There fore, the height of the tower = 24 units
Pablo makes a spinner to model the probability of simultaneously flipping a "heads" on a nickel, a "heads" on a dime, and a "heads" on a quarter. He divides his spinner wheel into sections for each possible combination of coin flips, and he colors green the section representing simultaneously flipping three "heads." If he decides to spin the arrow on the spinner 24 times, how many times can he predict the arrow will land on the green section?
times
Using proportions, it is found that he predicts that the arrow will land on the green section 24 times.
What is a proportion?A proportion is a fraction of a total amount.
Considering that each trial has a 1/2 probability of resulting in heads, the fraction correponding to the probability of simultaneously flipping three "heads" is given by:
[tex]p = \left(\frac{1}{2}\right)^3 = \frac{1}{8}[/tex]
Considering that he does this 24 times, we apply the proportion, hence:
[tex]\frac{1}{8} \times 24 = 3[/tex].
He predicts that the arrow will land on the green section 24 times.

Let the number of baskets made by Whitney be x.
The 15 baskets made by
Chiyann is equal to 2 times plus 3 what Whitney made
Mathematically what she made would be 2x + 3
