Bob needs to mix 5 cups of liquid lemonade concentrate with 2.5 cups of water to make lemonade. Bob has 2.5 cups of liquid lemon

Julli [10]

Answer:

3.75 cups

Step-by-step explanation:

Given that :

5 cups of liquid lemonade concentrate is mixed with 2.5 cups of water to make lemonade

5 cups of lemonade = 2.5 cups of water

Ratio :

5 / 2.5

For 2.5 cups of lemonade :

5 / 2.5 = 0.5

Multiply :

5 / 2.5 * 0.5 / 0.5

2.5 / 1.25

Hence, 2.5 cups + 1.25 cups = 3.75 cups of lemonade will be made with 2.5 cups of liquid lemonade concentrate

Math help pls!! answer choices are 17.1 , 3.5 , 8.4 , and 1.5

Hoochie [10]

Triangles ABD and BCD are similar, because they are both right and share a common angle, and thus all three angles are equal.

This means that we can set the proportion

$AB\div AD = BC\div DC$

Plug the numbers and we have

$5\div 3.5 = 12\div x$

Solve for $x$ :

$x=\dfrac{12\cdot 3.5}{5}=8.4$

Answer:

Please check the explanation.

Step-by-step explanation:

Determining the length of BC

From the diagram, it is clear that

The point B is located at (-8, 10) and point C is located at (8, 10)

Since points A and C are located on a horizontal straight line. Thus, the length of BC can be determined by counting the x-axis units from reaching x = -8 to x = 8. i.e. 8-(-8) = 8+8 = 16

Thus, the length of BC = 16 units

Determining the length of CD

Given

C (8, 10)

D (2, -2)

The distance between C(8, 10) and D(2, -2)

$\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$CD=\sqrt{\left(2-8\right)^2+\left(-2-10\right)^2}$

$=\sqrt{6^2+12^2}$

$=\sqrt{36+144}$

$=\sqrt{180}$

$=\sqrt{36\times 5}$

$=6\sqrt{5}$

Thus, the length of CD $=6\sqrt{5}$ units

Determining the length of ED

Given

E (-8, -4)

D (2, -2)

The distance between E(-8, -4) and D(2, -2)

$ED=\sqrt{\left(2-\left(-8\right)\right)^2+\left(-2-\left(-4\right)\right)^2}$

$=\sqrt{10^2+2^2}$

$=\sqrt{100+4}$

$=\sqrt{104}$

$=\sqrt{26\times \:4}$

$=2\sqrt{26}$

Thus, the length of ED $=2\sqrt{26}$ units

Determining the length of EB

From the diagram, it is clear that

The point E is located at (-8, -4) and the point B is located at (-8, 10)

Since points E and B are located on a vertical straight line. Thus, the length of EB can be determined by counting the y-axis units from reaching y = -4 to y = 10. i.e. 10-(-4) = 10+4 = 14

Thus, the length of EB = 14 units

The 4 angles of heptagon equal and each of other 3 is 20° greater the first 4.Find the angles

GenaCL600 [577]

Answer:

interior angle of a heptagon = 900 degrees

900 = 4x + (3x + 60)

840 = 7x

840/7 = 120

X = 120

120 X 4 = 480

120 X 3 = 360

480 + 360 + 60 = 900

4 angles = 120 degrees each

3 angles = 140 degrees each
