Justine is planting flowers in a line that is 1/2 of a yard long. She is going to plant 6 flowers. How far apart will each flower be?

Responder:

1,78 cm

Explicación paso a paso:

El área de superficie total de la superficie esférica se expresa como;

T = 4πr² donde

r es el radio

Dado

TSA = 40 cm²

Sustituir

40 = 4πr²

r² = 40 / 4π

r² = 10 / π

r² = 10 / 3,14

r² = 3,185

r = √3,185

r = 1,78

por lo tanto, el radio de la esfera a la centésima más cercana es 1,78 cm

Answer:

11.64

Step-by-step explanation:

100%-> 48

15%-> 7.20

6.25%-> 3

48+7.20+3=58.20

58.20÷5=11.64

Answer:

Problem 7

Answers:

-----------------------

Explanation:

In step 1, there are 2 dots. So that number (2) fills in the blank for dots A.

Step 2 has 5 dots, which fills in the blank for dots B.

===========================================================

Problem 8

Answer: A) Quadratic

-----------------------

Explanation:

We have this sequence of dots: {1, 2, 5, 10, ...}

Note the increments of +1, +3, +5, ...

The increments aren't the same, so we don't have a linear sequence. But because the increment amounts go up by 2 each time, this strongly implies a quadratic sequence.

The rule for this sequence is n^2 + 1. Whatever the step number (n) is, we square it and add 1 onto that result. For instance, for step 3, we have n = 3 that leads to n^2 + 1 = 3^2 + 1 = 9 + 1 = 10. Also, note how the lone dot on the left of step 3 is tacked onto the 3 by 3 square of dots.

===========================================================

Problem 9

Answers:

-----------------------

Explanation:

Same idea as problem 7

===========================================================

Problem 10

Answer: B) Exponential

-----------------------

Explanation:

The sequence is {1, 3, 9, 27, ...}

In step 3 we have 3 rows and 9 columns of dots to give 3*9 = 27 dots total here.

The sequence is growing by a factor of 3 each time. In other words, we are tripling the terms or multiplying each term by 3 to get the next term.

Therefore, we have an exponential pattern.

The rule is 3^n

Eg: if we're on step n = 2, then we have 3^n = 3^2 = 9 dots.

Answer:

3/4

Step-by-step explanation:

the numerator of slope (in this case 3) is always y because y rises. in this case, in order to get to the other plot you need to rise three times then run 4. "run" is how many it takes to get to the plot but in the x direction. for example in this case it took 3 rise and 4 run.

Answer:

3(3x -6)=9x-18

4x +6+3=4x +9

Note: We need to find the number of seeds of each color.

Given:

A packet contains blue and yellow flower seeds in the ratio 3:4.

There are 32 flower seeds​.

To find:

The number of blue and yellow flower seeds.

Solution:

Let the number of blue and yellow flower seeds are 3x and 4x respectively.

There are 32 flower seeds​.

[tex]3x+4x=32[/tex]

[tex]7x=32[/tex]

[tex]x=\dfrac{32}{7}[/tex]

[tex]x\approx 4.57[/tex]

Now,

The number of blue flower seeds is

[tex]3(4.57)=13.71\approx 14[/tex]

The number of yellow flower seeds is

[tex]4(4.57)=18.28\approx 18[/tex]

We approx. the value rounded to the nearest integer because the number of flower seeds cannot be a decimal of fractional value.

Therefore, the number of blue seeds is 14 and the number of yellow seeds is 18.

Answer:

x=-2

Step-by-step explanation:

5x+4=-6 so basically what you want to do is try to get x by itself

step 1 subtract 4 from each side

5x=-10

step 2 divide each side by 5

x=-2

Answer:

20 ounces

Step-by-step explanation:

The line plot is attached below.

From the line plot, we can see that there is a total of 7 snack mix. Two of the snack mix weigh 1 and half (1.5) ounces each, one snack measure 2 and three quarter (2.75) ounce, three snack mix measure three and half (3.5) ounce each and one snack measure 3 and three quarter (3.75) ounce. Therefore the total weight of the snack mix is:

Total weight = (2 * 1.5) + (1 * 2.75) + (3 * 3.5) + (1 * 3.75)

Total weight = 20 ounces

Answer:

70?

Step-by-step explanation:

Answer:

A) $600

B) $1200

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

I = 600 × 0.1 × 10 = 600

I = $ 600.00

The simple interest accumulated

on a principal of $ 600.00

at a rate of 10% per year

for 10 years is $ 600.00.
