Answer:
whats the answer?
Step-by-step explanation:
The equation that represent the situation would be; 15+25d=t. Here the variable are d for distance and t for temperature.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that the surface temperature averages at 15 degrees Celsius and increases 25 degrees Celsius with each kilometer of depth.
We can conclude that the initial value is 15 it increases(+) by 25 to each kilometer(distance=d) of depth.
The equation becomes
15+25d=t.

Dominic is making meatballs. He uses 3/4 cup of breadcrumbs for every 1 1/4 pounds of ground beef. How many cups of breadcrumbs does he need when he uses 1 3/4 pound of ground beef? Show your work.
Answer:
1 1/20
Step-by-step explanation:
¾ / 1 ¼= ¾ / 5/4= ¾ x ⅘ = 12/ 20= ⅗
⅗ x 1 ¾ = ⅗ x 7/4 = 21/20= 1 1/20
Domonic needs 1 1/20 cups of breadcrumbs when he uses 1 ¾ pounds of ground beef.
[tex]$1 \frac{3}{4}[/tex] pound of ground beef requires [tex]$1 \frac{1}{20}[/tex] cup of breadcrumbs.
We have Dominic who uses 3/4 cup of breadcrumbs for every 1 1/4 pounds of ground beef.
We have to determine how many cups of breadcrumbs does he need when he uses 1 3/4 pound of ground beef.
If you solve 5 questions of mathematics in 2 hours. Then how many questions you will solve in 6 hours ?You will solve - 5 x [tex]$\frac{6}{2}[/tex] = 15 questions.
According to the question, we have -
[tex]$\frac{3}{4}[/tex] cup of breadcrumbs for → [tex]$1\frac{1}{4}[/tex] = [tex]$\frac{5}{4}[/tex] pounds of ground beef.
1 cup of breadcrumbs for → [tex]$\frac{\frac{5}{4} }{\frac{3}{4} }[/tex] = [tex]$\frac{5}{3}[/tex] pounds of ground beef.
This means -
[tex]$\frac{5}{3}[/tex] pounds of ground beef requires → 1 cup of breadcrumbs.
1 pound of ground beef requires → [tex]$\frac{3}{5}[/tex] cup of breadcrumbs.
[tex]$1\frac{3}{4} =\frac{7}{4}[/tex] pounds of ground beef requires → [tex]$\frac{3}{5}\times \frac{7}{4} =\frac{21}{20} =1 \frac{1}{20}[/tex] cup of breadcrumbs.
Hence, [tex]$1 \frac{3}{4}[/tex] pound of ground beef requires [tex]$1 \frac{1}{20}[/tex] cup of breadcrumbs.

The sum of five consecutive integers is five. What is the product of the five integers?
The first integer = x
The second integer = x + 1
The third integer = x + 2
The fourth integer = x + 3
The fifth integer = x + 4
Since they all add up to 5, let's set them equal to 5
x + x + 1 + x + 2 + x + 3 + x + 4 = 5
Combine like terms
5x + 10 = 5
Subtract 10 from both sides
5x = -5
Divide each side by 5
x = -1
The first integer = x = -1
The second integer = x + 1 = -1 + 1 = 0
The third integer = x + 2 = -1 + 2 = 1
The fourth integer = x + 3 = -1 + 3 = 2
The fifth integer = x + 4 = -1 + 4 = 3
We can check this by adding all the integers together and making sure we get 5
3 + 2 + 1 + 0 - 1 = 5
Answer:
0
Step-by-step explanation:
If the sum of the integers is 5, then the arithmetic mean of the integers is [tex]$\frac{5}{5}=1$[/tex] . In five consecutive integers, the arithmetic mean is equal to the middle integer, which means the integers are -1, 0, 1, 2, 3 and the product is [tex]$\boxed{0}$[/tex].

Answer:
10+4i
Step-by-step explanation:
2*√25 + √-16.
Given
2*5+4i
Simplify the sqrts. If you are wondering where I got "i" from, "i" is √-1. "i" is short for imaginary number because there is no real number that can be a square root of a negative number. I got the 4 because it is the square root of -16
10+4i
I multiplied the 2 and the 5. This is the simplest form because you cannot add imaginary and real numbers together.

if 102 is a term in sequence n should have non decimal value
a +(n-1)d = 102

Marlene brought a pitcher filled with 10 cups of water to her volleyball game. The paper cups she brought hold Two-thirds of a cup of water each. How many paper cups can Marlene fill with water?
Which math sentence represents the problem?
Two-thirds divided by 10 = 20/30=1/15
10 divided by two-thirds = 30/2=15
10 divided by three-halves = 20/3] 6 and two-thirds
1/10 divided by two-thirds = 3/20
Marlene needs 15 paper cups to fill with water
An equation is an expression that is used to show the relationship between two or more variables and numbers.
Since each paper cups can hold Two-thirds of a cup of water, hence to hold 10 cups of water:
Number of water cups = 10 cups / (two- thirds) = 10 * 3 / 2 = 15
Marlene needs 15 paper cups to fill with water.

Answer:
the missing value is 9.33.
Step-by-step explanation:
given,
length (l) = 3x+2
breadth (b) = 4
perimeter(P) = 68 cm
now,
P = 2(l+b)
or, 68 = 2× ( 3x+2+4)
or, 68 = 2× ( 3x+ 6)
or, 68 = 6x+12
or, 68 - 12= 6x
or, 56 = 6x
or, 6x = 56
or, x = 56/6

What is the mean of the data?O 5
O 10
O 30
O 50
Answer:
D. 50
Finding out the mean is actually pretty simple. All you have to do is add up the numbers, then divide that by how many numbers there are. For this graph, here's what you do:
35 + 40 + 45 + 50 + 55 + 60 + 65 = 350
Since there are seven numbers, you divide 350 by 7.
350 ÷ 7 = 50
And that's your answer! hope this helps

a) The radius of a circular field is 42 m. Find the perimeter of the field. Also find the length of wire required to fence it with 5 rounds
263.89
263.89*5=1319.45
We are given with the radius of the circular field,
[tex]r = 42 \: m[/tex]
And, we have to find the perimeter of the field. Also, we have to find the length of the wire required to fence it with 5 rounds:
We know,
Perimeter of a circle = 2πr, where r is the radius of the circle, So let's find the perimeter by using this formula.
[tex]perimeter = 2\pi r[/tex]
[tex]perimeter = 2 \times \dfrac{22}{7} \times \: 42 m[/tex]
[tex]perimeter = 2 \times 22 \times 6 \: m[/tex]
[tex]perimeter = \boxed{264 \: m}[/tex]
Now, finding the length of the wire which is equals to 5 × Perimeter of the circular field.
[tex]length \: of \: wire = 264 \: m \times 5[/tex]
[tex]length \: of \: wire = \boxed{1320 \: m}[/tex]
And we are done !!
