Answer 1

Answer:

D. (43 +60) +40

Step-by-step explanation:

The purpose of changing the grouping in addition problems is to simplify the mental effort required as much as possible. This will generally mean grouping ...

"complementary" numbers, numbers with the same number of leading or trailing zeros, numbers with the same sign, and fractions with the same denominator.

Analysis

A. Numbers ending in 0 are already grouped; no change is needed.

B. Fractions with the same denominator are already grouped; no change is needed.

C. Numbers with the same (negative) sign are already grouped; no change is needed.

D. Numbers ending in zero could be grouped to make addition easier:

43 +(60 +40) . . . . regrouping would be useful

We also note that in A and D, the sum of numbers ending in zero is 100, so these numbers are "complements" of each other. This is another reason for grouping them together.

First, you would find the area of the rectangle using the formula A = L • W, which would then give you 24 cm2. Then you would find the area of the triangle using the formula A = bh1/2, which would the give you the answer of 8 cm2. Then you would have to find the area of the semi-circle, using the formula A = (r • r) • 3.14 / 2, which would then give you the answer of 25.12 cm2. Finally, you would have to add up all three area’s, so 25.12 + 8 + 24, which would then give you the final answer, which would be 57.12 cm2.

Step-by-step explanation:

-2x-10=2x+14 i need all the steps

Answers

Answer:

x = -6

Step-by-step explanation:

1. always group the unknowns in this case, we 'bring' over the -2x to the right side so it becomes

-10 = 2x + 2x +14

2. Move 14 to the left side,

-10 - 14 = 2x + 2x

3. Carry out addition on both sides,

-24 = 4x

4. Simplify: since 24 is divisible by 4, so we divide 4 on both sides

-6 = x

Answer: x=-6.

Step-by-step explanation:

First, we need to choose an x side, and a non-x side. Let's choose the right side as the x side since it's coefficient of x is greater than that of the left side. So, we add 2x on each side to get rid of the x on the left side. Now, we have -10=4x+14. Next, we should subtract 14 from each side to get rid of the non-x terms on the right side. Now, we are left with -24=4x. Finally, we can divide by four on each side to get x=-6.

A storage box has a volume of 56 cubic inches, and the base of the box is 4 inches by 4 inches.

What is the height of the box?

Answers

The height of the box is 3.5in or 3 1/2in

Ok, so first we need the equation. So we know that v=b*w*h. We know that the base is 4 inches and the width is 4 inches as well. So we get the equation v=4*4*h. The volume is also given so the equation changes to 56=4*4*h. So first we multiply the numbers we have to get 56=16*h. Then we divide 16 on both sides. 56/16 is 3.5. We end up with 3.5=h. So the answer is 3.5 inches. You can also put this back in to make sure it is right. To 56=4*4*3.5 is true. So therefore, the answer is 3.5 inches.

Step-by-step explanation:

1. The weird circle looking thing essentially means you're putting p(x) inside of q(x). This means you take the x in q(x) and replacing with the entire p(x)

so q(x) = -3x - 4

(q °p)(x) = -3 (-2x+4) -4 sorry I can't find the actual circle thing symbol

now distribute to get the simplified equation:

= 6x -12 -4

= 6x - 16

because you're doing (q - p )(3), you would plug 3 for x into the new equation

6(3) - 16 = 2

and thats you're answer for the first one

for the second one its the other way around, so you're putting all of q(x) into p(x)

take p(x) : -2x+4

and now replace the x with the entire q(x)

so (p - q)(x) = -2 (-3x-4) +4

simplify: = 6x+8+4 = 6x+12

so now since we're doing (p-q)(3), we need to plug in 3 for x in the new equation

= 6(3)+12 = 30

lmk if those were wrong or if my explanation was unclear, there's another way I can explain it even though its the same process :)

Other Questions

If the sum of 37 and 12 x is 286, what is the value of x? Phage are viruses that must infect bacteria to reproduce. Viral genomes do not contain all the genes needed to produce all proteins necessary for DNA replication, RNA transcription, and protein translation; instead the viruses force bacterial proteins and enzymes to express phage genes instead of bacterial genes.Phage are very adaptable, and their behavior depends on whether conditions are favorable or unfavorable for making more phage.When bacteria are plentiful (favorable conditions), viral DNA within the bacteria remains separate from the bacterial chromosome, and the virus forces the bacteria to make more virus. When the amount of virus becomes too much for the cell to hold, the membrane ruptures, and viruses are released to infect surrounding bacteria. This is known as the lytic cycle.When bacteria are scarce (unfavorable conditions), the viral DNA within the bacteria becomes integrated into the bacterial chromosome. The bacteria survive and are still able to reproduce; viral DNA is transmitted to daughter cells when the bacteria reproduces. This is known as the lysogenic cycle.As you just read, phage depend on bacteria to reproduce. Phage can be maintained by infecting a culture of bacteria with a strain of phage, and then plating the bacteria on an agar plate to grow.Suppose that you isolate two mutant strains of phage - one strain cannot enter the lytic cycle and the other strain cannot enter the lysogenic cycle. You also grow wild-type phage as a control. You see three different phenotypes:A plate with no missing bacteria- the lawn of bacteria is intactA plate with spots/circles (called plaques) where there are absolutely no bacteria in the circlesA plate with spots/circles (called plaques) where there are some bacteria in the center of the circles.Based on what you know about what happens in each cycle, match the plating results with the identity of the strain.Drag each plate into the correct category.
