The temperature dropped 4°C every hour for 7 hours. What was the total number of degrees the
temperature changed in the 7 hours?
The total change in the temperature was
C.

Answer:

m/2= 134 degrees

Step-by-step explanation:

90 - 34 = 56

180 - 56 = 134

So angle 2 would be 134 degrees.

Answer:

4620

Step-by-step explanation:

3 time110=330 a week

3 times 14=42 pratices

3 times 42 =4620

Answer:

Let the price before increase be 100

Increased price =25percent of 100

25/100*100+100=125

When the price is increased to 125 she has to reduce 25

When the price is increased to 1 she has to reduce 25/125

Rate by which consumption decreases=25/125*100

=20 percent

Therefore she has to reduce 20percent consumption of onion so that there will be no change in her expenditure

Answer:

Step-by-step explanation:

A monomial is one term, which may be a constant. In the context of a polynomial, the literals in a term have non-negative integer exponents.

A fraction with a variable in the denominator is a rational expression, not considered to be a "term."

2/x and 5/y are not terms, so not monomials.

_____

Further explanation

In a larger context, a term is any mathematical expression that is to be considered as a unit. It may include radicals, rational expressions, even sums or differences. So, the expressions 2/x and 5/y may be considered to be terms in a different context than here. For example, we could say that ...

  2x⁻¹ +5y⁻¹

is a 2-term expression, though it could not be part of any polynomial.

Answer:

There are 800 girls and 1000 boys.

Step-by-step explanation:

The total no of students enrolled = 1800

Ratio of boys to the girls is 4:5.

Let there are 4x boys and 5x girls.

ATQ,

4x+5x=1800

9x=1800

x = 200

No of boys = 4x = 4(200) = 800

No of girls = 5x = 5(200) = 1000

So, there are 800 girls and 1000 boys.

Answer:

the width would be 57cm

Step-by-step explanation:

to find the perimeter you have to add up all of the sides so for this one you would multiply 83 by 2 which would give you 166cm and then subtract it by 280cm which would give you 114cm and then you divide 114 by 2 which would give you 57

Answer:

12x+15>120, choice C

Step-by-step explanation:

$12/person

$15/guide

X=12

It cannot be B or D because she only has 120 to spend. It is not possible to spend more than that. It cannot B either because X=12, the number f friends she can invite which is our unknown variable. The answer has to be C. It makes the most sense.

Answer:

y = 5 - 2x

Step-by-step explanation:

Answer:

y=5-2x

Step-by-step explanation:

[tex]3y = 15 - 6x[/tex]

[tex]y = \frac{15 - 6x}{3} [/tex]

if you divided it

[tex]y = 5 - 2x[/tex]

i think this is the answer

Answer:

The answer has to be -6.

Step-by-step explanation:

The slope of the equation is 3. The slope is always by the X. So your answer is -6.

Answer:

slope = [tex]\frac{5}{8}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 8, 7) and (x₂, y₂ ) = (16, 22)

m = [tex]\frac{22-7}{16+8}[/tex] = [tex]\frac{15}{24}[/tex] = [tex]\frac{5}{8}[/tex]

Answer:

x=-10

Good Luck!!!

A line passes through A( - 1 , 3) & B(0 , 2).

A , B , C(1 , 1) are collinear.

We know that,

Slope of a line passing through the co - ordinates (x₁, y₁) and (x₂ , y₂) is :

m = (y₂ - y₁)/(x₂ - x₁)

Let,

Hence,

→ m = (2 - 3)/( 0 - ( - 1))

→ m = - 1/1

→ m = - 1

Now,

Equation of a line ⟹ y - y₁ = m (x - x₁)

Putting the values we get,

→ y - 3 = - 1(x - ( - 1))

→ y - 3 = - x - 1

→ y + x = - 1 + 3

→ x + y = 2

Hence, the equation of the line is x + y = 2.

Now,

we have to prove that,

A , B , C are collinear.

i.e.,

Slope of AB should be equal to Slope of BC.

We have;

Slope of AB = - 1.

→ - 1 = ( 1 - 2)/(1 - 0)

→ - 1 = - 1/1

→ - 1 = - 1

Hence, A , B , C are collinear points.

I hope it will help you.

Answer:

heres ur answer x=2

heres what i used to solve it PEMDAS

Answer:

Step-by-step explanation:

Firstly, let us solve for Bobs speed

speed= distance/time

given

distance= 4 laps

time= 10 min

speed= 4/10

speed=0.4laps/min

this is the rate at which Bob is running

A) How many minutes per lap is that?

this is given as

=time/distance

=10/4

=2.5 min per lap

B) How many laps per minute is that?

this is given as

=distance/time

=4/10

=0.4lad per min

C) If Bob runs 17 laps at the same rate, how long does it take him?

given that the speed is 0.4 laps per min

and a distance of 17 laps, we want to find time

speed=distance/time

0.4=17/time

time=17/0.4

time=42.5min

Answer:

It would be A 0.20mm

Step-by-step explanation:

It would be A because there are 12 coins in that stack with the stack's height being 2.40

Divide 2.40 by 12

2.40/12=0.20

Hope this helps

Answer:

The answer is C: x = 2

Step-by-step explanation:

the answer above is wrong I jus took the test

Answer:

x=2

Step-by-step explanation:

The average is calculated by the sum of the total test scores divided by the total number of tests. This can represented in the equation:

91 + 86 + x /3 = 90

177 + x /3 = 90 ⇒ Multiply both sides by 3 to get rid of the /3

177 + x /3 x 3 = 90 (3)

177 + x =

177 - 177 + x = 270 - 177 ⇒ Subtract 177 from both sides to isolate x

x =93

Therefore, they must get 93% to end with a 90% final mark
