4x + 3y = 7

Answer:

The answer is Deserea.

Step-by-step explanation:

Dont worry, this is simple :)

If you have a dozen cookies, that means you have 12 cookies!

And 1/4 of 12 is simply 12 divided by 4, which equeals 3, so Carla ate 3 cookies.

And Deserea ate ½ of the cookies, which is 12 divided by 2, which is 6! So Deserea ate 6 cookies.

6 is greater than 3. So Deserea ate more Cookies!

Hope this helps!

Step-by-step explanation:

Answer:

800 ÷ 30 = 26.66666666666667 or 26.

Step-by-step explanation:

Answer:

yes

the sides bear a similar proportion to each other

CE = 1.67BC

CD = 1.67AC

Step-by-step explanation:

Two triangles are similar if the corresponding angels are congruent to each other and if the sides of the triangle are in proportion to each other

to determine if the triangles are similar, determine if the sides are in proportion to each other

CE = 10

BC = 6

10 / 6 = 1.67

DC = 15

AC = 9

15/9 = 1.67

The sides of the triangle are in proportion to each other, thus they are similar

Answer:

C

Step-by-step explanation:

Given

x² - 36 = 0 ( add 36 to both sides )

x² = 36 ( take the square root of both sides )

x = ± [tex]\sqrt{36}[/tex] = ± 6

That is x = - 6, x = 6 → C

Answer:

24 inches

Step-by-step explanation:

We can find different sides of a right angle triangle using Pythagorean theorem: [tex]c^2 = a^2+b^2[/tex], where [tex]c[/tex] is the hypotenuse and [tex]a[/tex] and [tex]b[/tex] are the other sides.

Therefore, we can re-arrange the equation for one of the other sides.

[tex]c^2-b^2=a^2[/tex].

Since we know these two sides all we have to do is put them into the equation:

[tex](30)^2-(18)^2=a^2[/tex]

[tex]a^2 = 576\\a= 24[/tex]

Therefore, the missing side is 24 inches.

kahn

It it was a whole rectangle: 12 x 9 = 108 square yards

Subtract the cut out area: 6 x (9-3) = 6 x 6 = 36 square yards

Total area = 108 - 36 = 72 square yards

Answer:

[tex]\sin A=\frac{12}{37},\\\\\cos A=\frac{35}{37},\\\\\tan A=\frac{12}{35}[/tex]

Step-by-step explanation:

In a right triangle only, the sine of an angle is equal to the angle's opposite side divided by the hypotenuse of the triangle. (o/h)

The cosine of the angle is equal to the angle's adjacent side divided by the hypotenuse of the triangle. (a/h)

The tangent of the angle is equal to angle's opposite side divided by the adjacent side. (o/a)

In this case, angle A's opposite side is 12, its adjacent side is 35, and the hypotenuse is 37 (o=12, a=35, h=37).

Thus we have:

[tex]\sin A=\frac{12}{37},\\\\\cos A=\frac{35}{37},\\\\\tan A=\frac{12}{35}[/tex]

Answer:

Step-by-step explanation:

sin A=opposite/hypotenuse=12/37

cos A=adjacent/hypotenuse=35/37

tan A=opposite/adjacent=12/35

Step-by-step explanation:

The volume of a sphere with a diameter of 9.3 is 521.

The amount of space occupied by a three-dimensional figure as measured in cubic units.

Volume of sphere is = 4/3*π*r³

d=9.3, radius= 9.3/2

Volume of sphere = 4/3*22/7*4.65*4.65*4.65*4.65

                               = 421.16 m³

                                = 521

Answer:

3x

Step-by-step explanation:

What you know

This is an equilateral triangle

the x's are all the same

you could write x + x + x = 3x = 16

Multiplying is just adding repeatedly

Answer:16 = 3x

Step-by-step explanation:

Perimeter = Sides surrounding a figure

The triangle has 3 sides, each named "x".

Thus, because the perimeter is equivalent to 16 inches, 3x = 16.

Given:

The diagram of a circle.

To find:

The radius or diameter and its length, segment EB.

Solution:

If a line segment connects the center of a circle and a point on the circumference of the circle, then the line segment is known as radius.

In the given figure A is the center of the circle and points B, C, E, D are on the circumference of the circle.

So, AB, AC, AE, AD are radii of the given circle.

[tex]AB=AC=AE=AD=4\text{ cm}[/tex]

If a line segment connects two points on the  circumference and passes through the center of the circle, then the line segment is known as diameter of the circle.

In the given figure B and E are two points on the circumference of the circle and the segment BE  passes through the center A. So, BE is the diameter of the circle.

Length of the diameter is:

[tex]EB=AE+AB[/tex]

[tex]BE=4+4[/tex]

[tex]BE=8[/tex]

Therefore, the segment EB is a diameter and length of the segment EB is 8 cm.

The difference of the two means is not significant, so the null hypothesis must be accepted.

Answer:

m∠1 = 70°

Step-by-step explanation:

Step 1

Sum of angles on a straight line = 180°

Hence:

180° - 101°

= 79°

Sum of interior angles in a triangle = 180°

Hence

m∠1 = 180° - (79 ° + 31°)

m∠1 = 70°

Answer:

317

Step-by-step explanation:

2(5-(-3))² + 7(-3)

2(5+8)² + (-21)

2(13)² - 21

2(169) - 21

338 - 21 = 317

Answer:

the sum of the interior angles = 360°

A kite has 4 sides.

This is the formula for the sum of the interior angles of any polygon:

N = number of sides

the sum of the interior angles = (N x 180°) - 360°

so, N = 4, then:

(4 x 180°) - 360° = 360°

Answer:

D

Step-by-step explanation:

To get from ΔXYZ (the figure on the right) to ΔX′Y′Z′ (the figure on the left), each point is translated left 6 units and down 1.

Movement left and right is related to the x-axis. So moving 6 units left (in a negative direction) is x - 6.

Movement up and down is related to the y-axis. So going down (in the negative direction) is y - 1.

Answer:

The standard repayment plan.

Step-by-step explanation:

Here is the complete question :

SARAH makes $43,000 per year, is single, and lives in Connecticut. She has $19,000 in subsidized loans and $8000 in unsubsidized loans. Which repayment plan will be the cheapest for her in total?

The standard repayment plan is a repayment plan where a fixed sum is paid monthly for 10 years. This makes a total of 120 payments. The advantage of the standard repayment plan over the federal repayment plan is that less interest is paid and payment is made over a shorter period

Because unsubsidized loans accrue a higher interest expense when compared to subsidized loans, Sarah should pay off her unsubsidized loan first. This would minimise interest payment

Answer:

Then g = 5.

Step-by-step explanation:

The only number that fits in g is 5.

2*5 - 4 = 6

So 2 x 5 = 10.

Which the equation is now 10 - 4 = 6.

So the answer is 5.

Answer:

g = 5

Step-by-step explanation:

2g - 4 = 6

2g - 4 + 4 = 6 + 4

2g = 10

2g ÷ 2 = 10 ÷ 2

g = 5

Answer: b=8 m=2

Step-by-step explanation: when x is 0 y=8 so that gives you the y-intercept. When you subtract 8-6 its 2 which is over 2 which is 2

Answer: y = -2x + 4

Step-by-step explanation:

First, you can find b (the y-intercept) from the coodinates. Where y=0, x=4. This is your y intercept (b).

To find the slope (m), take two points from the graph:

Let's use (2,4) and (3,2). Next, find the difference in the x and y values.

Difference in Y = 4-2 = 2

Difference in X = 2 - 3 = -1

Now we can find the slope by dividing the difference in y values by the difference in x values:

2/-1 = -2 (m = -2)

Now plug the values for b and m into your equation.

y = -2x + 4
