okay Is the answer c ??

Answer:

(x,y) = (-2,7)

Step-by-step explanation:

7x+2y=0

9x+4y=10

y = -9x/4 + 5/2

7x+2 (-9x/4 + 5/2) = 0

5x/2 = -5

5x = -10

x = -2

use x and substitute to get y

y = -(9/4) (-2) +5/2 = 7

Answer: 4 gallons per day

Step-by-step explanation:

From the question, we are informed that the Snyder family uses up a 12 -gallon jug of milk every 3 days.

The rate at which they drink milk will be gotten by dividing the gallons of milk they drink by the number of days. This will be:

= 12/3

= 4 gallons per day

Therefore, the rate they use in taking milk is 4 gallons per day.

Answer:

$2,407.5

Step-by-step explanation:

To solve this question, we will use the formula for calculating the amount formula as shown;

A =P(1+r)^n

Given that;

P = #$1300

r = 4.5% = 0.045

t = 14years

Substitute

A = 1300(1+0.045)^14

A = 1300(1.045)^14

A = 1300(1.8519)

A = 2,407.5

Hence Isabella would have $2,407.5 in her account after 14years

Answer:

Volume is 243.75

Step-by-step explanation:

v=(7.5)(5)(6.5)=243.75

Answer:

B = 115

Step-by-step explanation:

Since A and B are supplementary, they add up to 180 degrees.

Thus, 65 + B = 180, and B = 115

Answer:

71.77cm

Step-by-step explanation:

Answer:

71.76 cm^2

Step-by-step explanation:

The composite figure is made up of a rectangle with a missing half circle and a triangle.

area = area of rectangle + area of triangle - area of half circle

For the circle, radius = r = diameter/2 = 7 cm/2 = 3.5 cm.

area = LW + bh/2 - (pi)r^2/2

area = 10 cm * 7 cm + 7 cm * 6 cm/2 + (3.14)(3.5 cm)^2/2

area = 70 cm^2 + 21 cm^2 - 19.24 cm^2

area = 71.77 cm^2

Answer: 71.76 cm^2

In a right triangle, the hypotenuse is √2 x the legs. In this case, the value of x is [tex]\frac{18}{\sqrt{2} } =\frac{18\sqrt{2} }{2} =9\sqrt{2}[/tex].

Answer:

35°

Step-by-step explanation:

set it equal to 180 because the total sum of the interior angles of a triangle is equal to 180

x+x-15+95=180

2x+80=180

2x=100

x=50

now plug it in

50 - 15 = 35

answer

35°

Step-by-step explanation:

x+x-15+95=180

2x+80=180

2x=100

x=50

50 - 15 = 35

Answer:

The relationship between r and V is not linear.

Step-by-step explanation:

The volume increases exponentially as r increases linearly.

Volume of a cylinder is directly proportional to the square of its radius, we can say that there is a linear relationship between the radius and the volume of a cylinder.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Volume of a cylinder is V = πr²h,

where r is the radius

h is the height of the cylinder.

If we keep the height of the cylinder constant and vary the radius, we can see that the volume of the cylinder increases as the radius increases.

In fact, we can express this relationship as a linear equation in the form of y = mx + b,

where y is the volume, x is the radius, m is the slope, and b is the y-intercept.

By rearranging the volume formula, we get V = πr²h, which can be written as y = mx + b, where m = πh and b = 0.

Therefore, since the volume of a cylinder is directly proportional to the square of its radius, we can say that there is a linear relationship between the radius and the volume of a cylinder.

Answer:

Height of the house will reduce by 22 feet after 11 days.

Step-by-step explanation:

A house is sinking at the rate of 2 inches per day.

That means rate of sinking of the house is 2 inches in a day.

Therefore, house will sink or change in height of the house in 11 days

= Rate o change in height × Number of days

= 2 × 11

= 22 feet

Height of the house will reduce by 22 feet after 11 days.

Answer:

113

Step-by-step explanation:

note: to find the circumference of a circle using the radius, you use this equation -- 2[tex]\pi[/tex]r. since the radius is 18, you make the equation 2[tex]\pi[/tex]18. that gets you 36[tex]\pi[/tex], which, if put into the calculator, is about 113.
