The number of bacteria in a Petri dish grows by 10 percent every hour. After the growth, about 100 bacteria die. Suppose there are 500 bacteria, how many bacteria are alive after 1 hour
Answer:
450 bacteria
Step-by-step explanation:
Find growth that comes from precentage.
a = pw
a = 1.10(500)
a = 550
Then kill 100 bacteria.
b = 450

This diagram shows the dimensions of a concrete piece used to build a deck.
What is the volume of the concrete piece?
Three-dimensional figure that could be formed by placing two rectangular prisms together to form an L shape where the longer part of the L is on the bottom and the shorter part of the L extends up from the left side. The longer part of the L has a length of 20 inches, a width of 9 inches, and a height of 9 inches. The shorter part of the L extends 10 inches above the longer part of the L and has a length of 5 inches.
Answer:
The student is wrong, the total area = 16 ft² + 20 ft²
Step-by-step explanation:
See the attached figure.
The shown figure is a composite area of:
1) A rectangle with length of 8 ft and width of 4 ft
2) A triangle of base (8 - 4 = 4ft) and height of ( 6 - 4 = 2 ft)
The area of the rectangle = length x width = 8 * 4 = 32 ft²
The area of the triangle = 0.5 base x height = 0.5 * 4 * 2 = 4 ft²
So, the total area = 32 + 4 = 36 ft²
OR
The figure can be consists of :
1) A square of side length of 4 ft
2) A trapezoid of height (8-4 = 4 ft) and the bases length is (6 and 4 ft)
So,
The area of the square = 4 * 4 = 16 ft²
The area of the trapezoid = 0.5 (6+4) * 4 = 5 * 4 = 20 ft²
So ,the total area = 16 + 20 = 36 ft²
So,
The student is distracted, he finds the area of total rectangle of sides 8 and 6 ft, he should subtract from it the area of the trapezoid of height 2 ft and bases of 4 and 8 ft
So, the student is wrong
The volume of the concrete piece is 1000 cubic inches.
What is the Volume?Volume is a measure of the amount of space that an object occupies. It is a three-dimensional measurement that is typically expressed in cubic units.
here, we have,
given that,
The given diagram shows a rectangular concrete piece with dimensions 5 inches, 10 inches, and 20 inches.
The volume of a rectangular prism can be calculated as:
V = l × w × h
Where "l" is the length, "w" is the width, and "h" is the height. So, for the concrete piece, the volume is:
V = 5 in. × 10 in. × 20 in.
= 1000 cubic inches.
Hence, the volume of the concrete piece is 1000 cubic inches.

Find the y-intercept and x-intercept of the line. 5x-4y=20
Answer:
y intercept : (0,-5) slope 5/4
x= 4+ 4y/5
Step-by-step explanation:
5x-4y=20
+4y=20 + 4y add 4 to each side
5x= 20/5 + 4y/5 divide both sides by 5
x = 4 +4y/5

The school that Elisa goes to is selling tickets to a fall musical. On the first day of ticket sales the
second day by selling 4 adult tickets and 5 child tickets. What is the price each of one adult
ticket and one child ticket?
Answer:
x+y=4+8=12
$12 for one of each
or if you mean indivually (the wording confused me)
$4 for child, $8 for adult
Step-by-step explanation:
x=adult
y=child
2x+10y=56
4x+5y=52
iin order to be able to subtract values and find x and y im going to multiply 4x+5y=52 by two and get 8x+10y=104
8x+10y=104
-2x+10y=56
6x=48 divide each side by 6
x=8
plug 8 back into an equation to find cost of y
2(8)+10y=56
-16 -16
10y=40
y=4

Find the linear equation for the following functions
Answer:
1st one) y = x - .8
Step-by-step explanation:
1st one) you start by finding the slope of the line which can be found with y1 - y2/x1 - x2 (in this case: 3.6-2.4/2-1 which = 1/1, or the slope is one). now that we know the slope we need to find the x intercept or the point that the line intercepts the x axis, or when y = 0. We know that that for every one we subtract from x, we subtract one from y (hence the slope 1/1). so when we subtract 1.2 from the y we subtract 1.2 from the x. so the x intercept is -.8. If we put this in y = mx+b we get y = x - .8
2nd one) you do the same thing for the 2nd one then

Answer: q-56 > 0
Step-by-step explanation:
STEP 1
Equation at the end of step 1
(q + 12) - 2 • (q - 22) < 0
STEP 2
Equation at the end of step 2
56 - q < 0
STEP 3
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number

WRITING LINE AR INEQUALITIES Nancy works at Love at First Bite bakery where she decorates cakes and cupcakes. It takes her an average of 4 minutes to decorate a cupcake and 32 minutes to decorate a cake. Last week, Nancy spent no more than 224 minutes decorating cakes and cupcakes. Assume x represents the number of cupcakes and y represents the number of cakes Nancy decorated. 1. Which inequality best represents the possible combinations of cupcakes and cakes Nancy decorated? 2. If Nancy decorated a total of 4 cakes last week, which inequality represents the possible number of cupcakes she decorated? 3. Is it possible that Nancy decorated 3 cakes and 32 cupcakes last week? Explain. a. 4x + 32y > 224 b. 4x - 32y < 224 c. 32x + 4y < 224 d. 4x + 32y < 224 a. X < 96 b. x < 24 C. X < 96 d. x < 24 1 2- 3 - > 1
Answer:
32
Step-by-step explanation:
The inequality which best represents the possible combinations of cupcakes and cakes Nancy decorated is 4x + 32y > 224
Given:
Time to decorate cupcake = 4 minutes
Time to decorate cake = 32 minutes
Total time spent decorating last week = more than 224 minutes
number of cupcakes = x
number of cakes = y
The inequality:
4x + 32y > 224
A total of 4 cakes last week4x + 32(4) > 224
4x + 128 > 224
4x > 224 - 128
4x > 96
x > 96/4
x > 24
Is it possible that Nancy decorated 3 cakes and 32 cupcakes last week?4x + 32y > 224
4(32) + 32(3) > 224
128 + 96 > 224
224 > 224
Therefore, it is possible that Nancy decorated 3 cakes and 32 cupcakes last week

A cookie recipe calls for ¾ cups of sugar. The recipe makes 20 cookies. How much sugar is required to make 80 cookies
Answer:
So based on the given problem above, it says that, for one batch with 3/4 cup of brown sugar can make 6 dozen big cookies. If we are to make 15 dozen cookies, what we need to do is to divide 3/4 cup of brown sugar by 6 dozen, and we get 0.125. This means that per dozen, it is equivalent to 0.125 cup of brown sugar. If we multiply it by 15 dozens, we get 1.875 cup or 1 and 7/8 cup of brown sugar.
Answer:
3 cups of sugar.
Step-by-step explanation:
80/20 = 4 batches
3/4 cups x 4 = 3 cups of sugar
