Answer:

∠a= 65°, ∠b= 115°, ∠c= 25°

Step-by-step explanation:

The sum of the angles in a triangle is 180°. This is abbreviated to '∠ sum of ∆'.

∠c +55° +60° +40°= 180° (∠ sum of ∆PQR)

∠c +155°= 180°

∠c= 180° -155°

∠c= 25°

∠a +60° +55°= 180° (∠ sum of ∆PQS)

∠a +115°= 180°

∠a= 180° -115°

∠a= 65°

The sum of the angles on a straight line is 180°. It's abbreviation is 'adj. ∠s on a str. line'.

∠b +∠a= 180° (adj. ∠s on a str. line)

∠b +65°= 180°

∠b= 180° -65°

∠b= 115°

The equation that represents the basketball team raising money is a linear equation

The equation that represents the total amount raised is 10x + 15y = 3050

From the question, we have the following parameters

A linear equation is represented as;

Ax + By = C

So, the equation that represents the total amount raised would be 10x + 15y = 3050

Hence, the equation that represents the total amount raised is 10x + 15y = 3050

Answer:

The ratio of cups of mixed nuts to cups of granola is /First, we need to get the total number of granola cups. This can be done by adding all the components' cups as follows:

number of granola cups = 6 + 2 + 0.5 + 1 + 1 + 0.5

number of granola cups = 11 cups

Now, we are given that:

number of cups of mixed nuts is 2 cups

To get the ratio between the cups of mixed nuts and total granola cups, we will simply divide the two quantities as follows:

Hope this helps :)

Step-by-step explanation:

Granola is a munchable snack that is prepared using various kinds of nuts, seeds, and sometimes a binding agent such as honey is used in the preparation of granola.

In the question above, we are giving the ingredients and quantities which is used in the preparation of granola

6 cups rolled oats, 2 cups mixed nuts, 1 /2 cup sesame seed, 1 cup dried cranberries, 1 cup dried unsweetened coconut, 1 /2 cup honey.

Step 1

We would be adding up the ingredients to find the total number of cups

6 + 2 +  + 1 + 1 +  = 11 cups

The total number of cups = 11 cups

Step 2

The cups of mixed nuts given in the question = 2 cups

The total number of cups of granola is given = 11 cups

Therefore, the ratio of cups of mixed nuts to cups of granola is 2 : 11

Step-by-step explanation:

14 years plus another 5 equals 19 years.

Step-by-step explanation:

Area of circle = πr², π = 22/7 or 355/133. Here it is said to use '3.14'. I will use the same.

Volume = cross-section area * height

Cross-section area of bigger one = π(3m)²

Volume = π(3m)² * height

= 9π * 5 m³ = 45π m³

Cross-section area of smaller one= π(1m)²

Volume = π(1m)² * height

= π * 5 m³ = 5π m³

Since a large part(cylinder of 1 m is not here):

Required volume = total volume - volume of smaller circle(cylinder)

= 45π - 5π m³

= 40π m³ = 40(3.14) m³

= 125.6 m³

Step-by-step explanation:

for the (a) put 6 in for x in h(x)=x/3

which looks like this...

h(6)=6/3 so, h=2

not put 2 in for x in g(x)=√3

which would end up as...

g(x)=√3 since there is no x in the equation

now finally put √3 in for x in f(x)=x^3

so, f(√3)= √3^3

which is... f(x)= 3√3

Answer:

to compare them, you have to get the same denominator. So you change the denominator to 24 by multipling 7/12 by 2, and 5/8 by 3. Then you have 14/24 and 15/24. This means that 5/8 is greater than 7/12

The coordinates of endpoint G is (-2, 23) if the midpoints of a GH is M(5, 7). One endpoint is H(12, -9).

It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).

[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]

It is given that:

The midpoint of a GH is M(5, 7). One endpoint is H(12, -9).

The coordinates of endpoint G (x, y)

Using mid-point theorem:

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division.

(x + 12)/2 = 5

x + 12 = 10

x = 10 - 12

x = -2

(y -9)/2 = 7

y - 9  = 14

y = 14 + 9

y = 23

Thus, the coordinates of endpoint G is (-2, 23) if the midpoints of a GH is M(5, 7). One endpoint is H(12, -9).

Answer:

Correct choice D. 2,500 square feet

Step-by-step explanation:

Area of a rectangle

The area of a rectangle of dimensions x, y is:

A=x.y

The diagram provided in the question is to a scale of 1 inch=16 ft.

We have provided a modified diagram where all the dimensions are also shown in ft.

The longer side of the shape is 4*16=64 ft

The smaller side of the shape is 3*16=48 ft

The bottom side of the store is 2 1/4*16=36 ft

The leftmost side of the store is 1 3/4*16=28 ft

We need to find the value of x and y.

The value of x is x=64 ft - 36 ft = 28 ft

The value of y is y=48 ft - 28 ft = 20 ft

The area of the whole rectangle of dimensions 48 ft and 64 ft is:

[tex]A1=48 ft * 64 ft = 3,072 \ ft^2[/tex]

The area of the small blue rectangle is:

[tex]A2=28 ft * 20 ft = 560\ ft^2[/tex]

The area of the store is:

[tex]As=A1-A2=3,072 \ ft^2- 560\ ft^2=2,512 \ ft^2[/tex]

Rounding to the nearest 50 square feet:

[tex]\boxed{As=2,500 \ ft^2}[/tex]

Correct choice D. 2,500 square feet
