Answer:

Ok, so I hope I understood the task. Here goes nothing

Step-by-step explanation:

So, first we calculate the area of the big rectangle,

(√63+√28)*√45 = 15√35

Then we calculate the area of the small rectangle

√7*√5 = √35

Then we do this to get the area left

15√35 - √35 = 14√35

Then we take

$14 \sqrt{35 } \div 15 \sqrt{35} = \frac{14}{15}$

That should explain it

Help me please im so mad :(:

Answer:

R- (-10, -3)

S- (-10, -6)

Q- (-5, -3)

P- (-5, -6)

Step-by-step explanation:

Well, Q and P would be the exact same coordinates since that land directly on the reflection line.

Basically, on this graph/question you can count how far away the vertices is from the reflection line.

For example, Point R is 5 units away from the reflection line, therefore I need to count over 5 times to the left from the reflection line for point R. (Idk if that makes sense or not, ask questions if you are confused).

SOLVE THE SIMULATENOUS EQUATIONS Y=X-2 AND Y= 3X+5

natta225 [31]

Answer: y = x-2

y = 3x + 5

x-2 = 3x+5

x+3x = 5+2

4x = 7

x = 7/4

y = x-2

y = 7/4 - 2

y = 7-8/4

y = -1/4

The average test scores for a particular test in algebra was 84 with a standard deviation of 5. What percentage of the students

Delicious77 [7]

Answer:

The percentage of the students scored higher than 89% is 15.87%

Step-by-step explanation:

we are given

The average test scores for a particular test in algebra was 84

so, mean is 84

$\mu=84$

a standard deviation of 5

so,

$\sigma=5$

we have

x=89

now, we can use z-score formula

$z=\frac{x-\mu}{\sigma}$

now, we can plug values

$z=\frac{89-84}{5}$

$z=1$

now, we can use calculator

and we get

$p(z>1)=0.1587$

So,

The percentage of the students scored higher than 89% is 15.87%

Suppose P(E) = 0.3. Find P(not E). Suppose P(not E) = 65%. Find P(E).

larisa [96]

Try this option:
1. rule: P(E)+P(not E)=1.
2. according to the rule above
P(not E)=1-P(E)=1-0.3=0.7;
P(E)=1-P(not E)=(100-65)%=35%.

Malia is planting tomato and pepper plants in her garden each tomato plant t requires 6 square feet and each pepper plant p requ

Misha Larkins [42]

4p + 6t ≤ 150 inequality represents this situation

<h3>Solution:</h3>

Given that,

tomato plant is represented by "t"

pepper plant is represented by "p"

Malia's garden has an area of 150 square feet

Given that each tomato plant "t" requires 6 square feet of space

So, the area required to plant "t" tomato plants:

= t x ( Area required by 1 tomato plant) = t x ( 6 sq ft) = 6t

Each pepper plant p requires 4 square feet of space

So, the area required to plant p pepper plants

= p x ( Area required by 1 pepper plant) = p x ( 4 sq ft) = 4p

Given that total area of garden = 150 square feet

area of "p" pepper plants + area of "t" tomato plants = 4p + 6t

So, now according to the question:

The area occupied by both plants must be less than or equal to total area of garden

Total area of both plants ≤ Total area of the garden

4p + 6t ≤ 150

Thus inequality is found
