Henry is making a corn grits recipe that calls for 1/4 cup of corn grits for every /12 cup of water. How much water will he need

riadik2000 [5.3K]

Corn Grits : Water
1/4 : 1/2
1/4 x 4 : 1/2 x 4
1 : 2
3/2 : 2 x 3/2
1 1/2 : 3

So he will need 3 cup of water if he uses 1 1/2 cup of corns grits.

Paul [167]

Answer:

Step-by-step explanation:

Given that the mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

Let X be the incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

X is N(25, 1)

a) Normal curve is in the attached file

b) the probability that a randomly selected fertilized egg hatches in less than 23 days

= $P(X$

we convert x into Z score and use std normal distn table to find probability

$P(X$

i.e. we can say only 2.5% proportion will hatch in less than 23 days.

Answer:

d ≈ 1732 ft

Step-by-step explanation:

Angle of elevation = Angle of depression

Following this truth,

m∠PAQ (Angle of depression) = m∠APB (Angle of elevation) = 30°

By applying tangent rule in the given triangle ABP,

tan(30°) = $\frac{AB}{PB}$

$\frac{1}{\sqrt{3}}=\frac{1000}{d}$

d = 1000√3

d = 1732.05

d ≈ 1732 ft

A wood board 156 centimeters long is cut into three parts .The two longer parts are the same length and are 15 centimeters longe

n200080 [17]

The everyone of two longer parts has 57 cm length and the shortest part has 42 cm length.
less 30cm from 156 and divide the remain amount of 126 into three parts. The answer will be 42 cm, then add 15,15 in longer parts.
