Solve: 14 = k(0.4) k = _____
Let's solve your equation step-by-step.
14=k(0.4)
Step 1: Simplify both sides of the equation.
14=0.4k
Step 2: Flip the equation.
0.4k=14
Step 3: Divide both sides by 0.4.
[tex]\frac{0.4k}{0.4}[/tex] = [tex]\frac{14}{0.4}[/tex]

Jannie bring 100 bags of candy to sell at the school fair. Each bag weighs 1lb and she plans to sell each for 66 cents. Jannie fills the bags with 40 lb of sugar candies worth 75 cents a pound, and some jelly beans. How much does 1 pound of jelly beans cost?
Answer:
60 cents
Step-by-step explanation:
The equation will be: the 40lb sugar candies worth 75 cents a pound added to 60lb (100-40) jelly beans worth x cents = 100 pounds worth 66 cents a pound
(.75 times 40)+(x times 60)= .66 times 100
30+60x=66
60x=36
x=.6
Meaning 60 cents

(i) Triangular pyramids and triangular prism have the same number of faces.
False. Triangular pyramids are tetrahedrons (Number of faces: 4) and triangular prisms are pentahedrons (Number of faces: 5).
(ii) Triangular prisms and rectangular prisms have the same number of bases.
True. All prisms have two bases.
(iii) Cubes and triangular pyramids have the same number of faces.
False. Triangular pyramids are tetrahedrons (Number of faces: 4) and cubes are hexahedrons (Number of faces: 6)
(iv) Triangular prisms and rectangular prisms have the same number of faces.
False. Triangular prisms are pentahedrons (Number of faces: 5) and rectangular prisms are hexahedrons (Number of faces: 6)
Therefore, the statement Triangular prisms and rectangular prisms have the same number of bases is true.

If 8 is an element in the domain of f(x)=6x-17/5, what is the corresponding element in the range Please help need it now by 2:05, 1/29/2021
Answer:
The corresponding element is 44 3/5
Step-by-step explanation:
Here, we want to calculate the f(x) value given the x value
what we simply do is to substitute 8 for x
we have this as;
f(8) = 6(8) - 17/5
f(8) = 48-17/5
f(8) = (5(48) - 17)/5
f(8) = 223/5 = 44 3/5
f(x) = x + 2, 2 < 0
f (x) = 4x, x > 0
what is f(-3)
Answer:
The zero of a function is the x-value that, when plugged into a function, makes the function equal to 0. f(x) means that we have a function of x. The zero of the function f(x)=2x-2 is the x-value that makes f(x) = 0. So we can just set the function equal to 0, and then solve for x!

1 7/9 divided by 4/5 =
Answer:
20/9
Step-by-step explanation:
16/9 * 5/4
4/9 * 5
20/9
The quotient of dividing the given fractions is 20/9.
Given that, 1 7/9=16/9 and 4/5.
From the given fractions we need to divide 16/9 by 4/5.
How to divide the fractions?A fraction represents a part of a whole or, more generally, any number of equal parts.
The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.
Now, 16/9÷4/5
Change ÷ to × and reciprocate 4/5 to 5/4.
Then, 16/9÷4/5=16/9×5/4=20/9
Therefore, the quotient of the given fraction is 20/9.

Mary works as a gardener. On her last job she charged $60 for plants and $500 for 20 hours of work. The equations represent the total price,y, charged by different gardeners after x hours of work. Click on all the equations that represent gardeners who charge a higher hourly rate than Mary. A. Y = 15x + 60 B. Y = 32x + 35 C. Y = 21x + 75 D. Y = 18x + 80 E. Y = 35x + 30 F. Y = 40x + 40
Answer:
B. Y = 32x + 35 E. Y = 35x + 30 F. Y = 40x + 40Step-by-step explanation:
First find out how much Mary was charging per hour:
= 500 / 20
= $25 per hour
She charges $60 for plants.
In a linear equation of the form: y = mx + c, the m represents the variable cost which in this case is the $25 per hour and the c is the fixed cost which is the $60.
Her rate as a linear equation would be:
y = 25x + 60
Looking a the value of the m of other gardeners will tell you who is charging higher hourly rates with anything above $25 doing so.
The gardeners with higher values of m than Mary are:
B. Y = 32x + 35
E. Y = 35x + 30
F. Y = 40x + 40
In the figure, 'O' is the centre of the circle, ZABO= 20°and ZACO= 30°, where
A, B, C are points on the circle. What is the value of x ?
120
Given:
Consider the below figure attached with this question.
[tex]\angle ABO=20^\circ[/tex]
[tex]\angle ACO=30^\circ[/tex]
To find:
The value of x.
Solution:
Draw a line segment OA as shown below.
In triangle ABO,
[tex]OA=OB[/tex] [Radii of same circle]
[tex]m\angle BAO=m\angle ABO=20^\circ[/tex] [Base angles of an isosceles triangle]
In triangle ACO,
[tex]OA=OC[/tex] [Radii of same circle]
[tex]m\angle CAO=m\angle ACO=30^\circ[/tex] [Base angles of an isosceles triangle]
Now,
[tex]m\angle BAC=m\angle BAO+m\angle CAO[/tex]
[tex]m\angle BAC=20^\circ+30^\circ[/tex]
[tex]m\angle BAC=50^\circ[/tex]
Central angle is always twice of angle subtended by two points on the circle.
[tex]m\angle BOC=2\times m\angle BAC[/tex]
[tex]x=2\times (50^\circ)[/tex]
[tex]x=100^\circ[/tex]
Therefore, the value of x is 100°.
