The numeric value of the expression d² + 3a + 6 + a when a = 2 and d = 5 is of 39.

<h3>How to find the numeric value of an expression?</h3>

The numeric value of a function is found replacing each instance of a variable by the value of the input for which we want to find the numeric value.

For this problem, the expression is given by:

d² + 3a + 6 + a

We want to find the numeric value when a = 2 and d = 5, hence:

5² + 3(2) + 6 + 2 = 25 + 6 + 6 + 2 = 39.

Use 3.14 for .Jenna is planting four circular gardens. She is planting one garden each for tomatoes, carrots, cabbage, and straw

Llana [10]

Um I assume you're wanting the circumferences of the fences so we have 3 that are all the same size and one that is 3 times as large as any of the others

so here's our equations

3x+y=113.04

y=3x

use substitution

3x+3x=113.04

6x= 113.04

now the question says use 3.14 so I'm thinking you want the answer in terms of pi so first divide 113.04 by 3.14

6x=36pi

x=6pi now substitute that back in for x in one of your equations

y=(3)(6pi)

y=18pi

so the tomatoes carrots and cabbage will all have a circumference of 6pi and the strawberries 18pi

Please help, will give brainliest answer

babymother [125]

1. AB/EF = P(ABCD)/P(EFGH)
4/5=16/P(EFGH)
P(EFGH)=5*16/4=5*4=20

2. V(old)=lwh =
V(new)=2*l*2*w*2*h =2³(lwh)=2³*V(old)= 8*3600=28800

3. A(old)=ab
A(new)=5a*5b=25ab=25A(old)
new area will be 25 times larger

Match the real-world problem to its constant of proportionality.

BabaBlast [244]

Answer:

a. $18.36 for 3 pizzas : k = 6.12

b. $4.17 for 3 pounds of bananas . k = 1.39

c. $16.48 for 4 pounds of potatoes . k = 4.12

d. 2 cups of flour to make 24 cookie . k = 2

Step-by-step explanation:

<u>PROPORTIONALITY:</u>

Two quantities x and y are said to proportional to each other

if for x ∝ y , x = y k.

Here, k i s called the PROPORTIONALITY CONSTANT.

⇒ $x \propto y \implies k = \frac{x}{y}$

Now, for the given quantities:

a. $18.36 for 3 pizzas [box]

Here, $k = \frac{18.36}{3} = 6.12$

So, the proportionality constant is 6.12.

b. $4.17 for 3 pounds of bananas [box]

Here, $k = \frac{4.17}{3} = 1.39$

So, the proportionality constant is 1.39.

c. $16.48 for 4 pounds of potatoes [box]

Here, $k = \frac{16.48}{4} = 4.12$

So, the proportionality constant is 4.12.

d. 2 cups of flour to make 24 cookies

Here, $k = \frac{24}{2} = 12$

So, the proportionality constant is 12

Alice and Amy decide to meet at a party. From a corner of the party hall, Amy spots Alice at the corner of the hall diagonally o

EleoNora [17]

Given that the hall is rectangular in shape, then the shortest path that Amy must travel to reach Alice would be through the hall's diagonal. Applying the Pythagorean theorem, with the length and width as the legs and the diagonal as the hypotenuse of the right triangle. Thus, diagonal = √ ( 100² + 60²) = √13 600 ≈ 116.62 ft The shortest distance, rounded off to the nearest foot, is 117 ft<span>. </span>
