Nico can complete 78 sit-ups in 2 minutes.
What is the ratio of sit-ups to minutes described above?

Answer:

x=67

Step-by-step explanation:

x+23+90=180

x+113=180

x=180-113

x=67

Answer:

answer is 67

Step-by-step explanation:

let use angle sum property

the sum if triangle is 180

if it is perpendicular it is 90 degree

180 is equal to 23+90+x

180 is equal to 133x

x is equal to 180-133

so we get 67

Answer:

38

Step-by-step explanation:

Its 38 beacuse 198 divided by 2 is 38

Answer:

C; 48x + 6 = 198

Step-by-step explanation:

4 8 + 6 = 1 9 8

4 8 + 6 − 6 = 1 9 8 − 6

= 4

all the number's were given is 6in with X inches, 48D/T with the result of 198, so we know 198 is the result of 48 days, so that means 48x. day + ^Y or the inches we started with

Answer:

<A = 55

<B = 125

<C = 55

<D = 125

Step-by-step explanation:

the two given angles in this are adjacent, adjacent angles in parallelograms are always supplementary

so we can set the equation to:

2x + 15 + x = 180

solve this to get x = 55

For <B plug in 65 to 2x + 15:

2(55) + 15 = 125

opposite angles in parallelograms are congruent, so B and D have the same measure and A and C have the same measure

knowing this, <D is also 125

<C is just x, so 55

and <A is opposite to <C so <A is also 55

Answer:

[tex]\huge\boxed{\sf \$ \ 63}[/tex]

Step-by-step explanation:

Original Price = $ 70

Discount = 10 % of $ 70

[tex]\sf = \frac{10}{100} * 70\\\\= 1 * 7\\\\= \$ \ 7[/tex]

Discount = $ 7

So,

Discounted Price = $ 70 - $ 7

= $ 63

Answer:

The Canadian nickel is 62.8 mm^2 greater in area as compared to Canadian penny.

Step-by-step explanation:

Diameter of Canadian penny = 19 mm

Diameter of Canadian nickel = 21 mm

We need to find How much greater is the area of a Canadian nickel than

the area of a Canadian penny?

First we need to find area of both nickel and penny

They are in circular form, so formula used is: [tex]Area=\pi r^2[/tex]

Finding area of Canadian penny

We know that radius = diameter/2

So, radius = 19/2

radius = 9.5

Area will be:

[tex]Area=\pi r^2\\Area=3.14*(9.5)^2\\Area=283.385 \ mm^2[/tex]

So, area of Canadian penny = 283.385 mm²

Finding area of Canadian nickel

We know that radius = diameter/2

So, radius = 21/2

radius = 10.5

Area will be:

[tex]Area=\pi r^2\\Area=3.14*(10.5)^2\\Area=346.185 \ mm^2[/tex]

So, area of Canadian nickel = 346.185 mm²

Difference in area can be calculated as: 346.185-283.385 = 62.8

The Canadian nickel is 62.8 mm^2 greater in area as compared to Canadian penny.

Given:

Perimeter of a triangle = 17 inches

First side is twice the second.

Third side is 3 inches less than the second side.

To find:

The measure of the longest side.

Solution:

Let the second side be x. Then,

First side = 2x

Third side = x-3

We know that, perimeter of a triangle is the sum of all three sides of it.

[tex](2x)+x+(x-3)=17[/tex]

[tex]4x-3=17[/tex]

[tex]4x=17+3[/tex]

[tex]4x=20[/tex]

Divide both sides by 4.

[tex]x=5[/tex]

Now,

First side = [tex]2(5)=10[/tex] inches

Second side = 5 inches

Third side = [tex]5-3=2[/tex]  inches

Therefore, the measure of the longest side is 10 inches.

Answer:

Depends on which point is the starting point.

If (7, -9) is the starting point, the slope is -19/4, or -4 and 3/4.

However, if (15, -29) is the starting point, the slope is -5/2, or -2 and 1/2.

Step-by-step explanation:

If (7, -9) is the starting point:

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]= \frac{-29 - 9}{15 - 7}[/tex]

[tex]= \frac{-38}{8}[/tex]

[tex]= -\frac{19}{4}[/tex]

The slope of the line is -19/4, or -4 and 3/4.

If (15, -29) is the starting point:

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]= \frac{9 - (-29)}{7 - 15}[/tex]

[tex]= \frac{20}{-8}[/tex]

[tex]= -\frac{5}{2}[/tex]

The slope of the line is -5/2, or -2 and 1/2.

Answer:

Theo worked for 12 hours and Kade worked for 15

Step-by-step explanation:

if kade worked for 10 hours Theo works for 7 so in total they worked for 17 hours together. So what you do is you just continue counting kades hours, subtracting 3 then add those number together till you get the total of 27 hours.

Answer:

Theo worked for 12 hours and Kade worked for 15

Answer:

C. 20

Step-by-step explanation:

45 + 5x + 35 = 180

5x + 80 = 180

subtract 80 from both sides

5x = 100

divide by 5

x = 20

Answer:

c = 20

Step-by-step explanation:

angle 2 + (5x + 35) = 180( angles on a straight line sum to 180)

Answer:

The selections are;

The system is inconsistent because the slopes are the same = Not correct

The system is independent because the y-intercept are different = Not correct

Step-by-step explanation:

An independent system of equations is a system that has only one solution, while an therefore, have different slope

An inconsistent has no solution, and therefore, have the same slope but different y-intercept

Therefore, we have;

The system is inconsistent because the slopes are the same = Not correct

The system is independent because the y-intercept are different = Not correct

Given:

The milk cost  in year 2000 = $2.79

In 2015, the cost of milk = $3.98

To find:

The % portion.

Solution:

We have to find the % portion. It means, we need to find the change percent.

[tex]\%\text{Change}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]

[tex]\%\text{Change}=\dfrac{3.98-2.79}{2.79}\times 100[/tex]

[tex]\%\text{Change}=\dfrac{1.19}{2.79}\times 100[/tex]

[tex]\%\text{Change}=0.4265233\times 100[/tex]

[tex]\%\text{Change}=42.65233\%[/tex]

[tex]\%\text{Change}\approx 42.65\%[/tex]

Therefore, the % portion is 42.65%.
