Marco's height is 63 inches. Marco's height is 3 inches less than 1.5 times Jennifer's height. What is Jennifer's height in inches? 40 in. B 44 in. C 64.5 in. D 58.5 in.
Answer:
B. 44 in.
Step-by-step explanation:
Let Jennifer's height be x inches, then:
1.5x - 3 = 63
1.5x = 66
x = 66/1.5
= 44 in.
A drug is available in 100mg/mL. The patient needs 0,75 g of the drug. How many mL should be administered.
Answer:
7.5 ml
Step-by-step explanation:
A drug is available in 100mg/mL.
This means, there is
100mg of the drug in 1 ml
100mg = 1 ml
Step 1
We convert 100mg to g
1 mg = 0.001 g
100 mg = x
Hence,
x = 100 × 0.001g
x = 0.1 g
Hence,
We have 0.1g in 1 ml
Step 2
The patient needs 0.75 g of the drug. How many mL should be administered?
From step 1, we know that:
0.1g = 1 ml
0.75g = x
Cross Multiply
0.1g × x = 0.75g × 1 ml
x = 0.75g × 1 ml/0.1g
x = 7.5 ml
Therefore, 7.5 ml should be administered to the patient.

Answer:
height = 12 feet
Step-by-step explanation:
r (radius of circle) = 7 ft
pi = 3.14 (in this context)
v = 1/3 * [tex]πr^{2}[/tex] (or pi * radius squared) * h
r squared = 49 ft
v = 1/3 3.14 * 49 * h
v = 1/3 153.86 * h
3v = 153.86 * h
v = 196π
v = 615.44
3v = 1,846.32
1,846.32 = 153.86 * h
h = 12 ft.
Find the gradients of lines A and B.

Answer:
Gradient of line A = 4
Gradient of line B = -2
Step-by-step explanation:
To solve this question, we will use the formula for gradient passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],
Gradient (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
For line A,
Since, line A passes through (3, 6) and (4, 10)
Gradient of line A = [tex]\frac{10-6}{4-3}[/tex]
= 4
For line B,
Since, line B passes through (1, 6) and (2, 4),
Gradient of line B = [tex]\frac{6-4}{1-2}[/tex]
= -2

Answer:
x = 50
Step-by-step explanation:
The chord- chord angle is half the sum of the arcs intercepted by the angle and its vertical angle, that is
[tex]\frac{1}{2}[/tex](x + 110) = 80 ← multiply both sides by 2 to clear the fraction
x + 110 = 160 ( subtract 110 from both sides )
x = 50

Step-by-step explanation:
Find the area of the green huge square.
36 x 36 = 1296
After that, find the area of the small square inside of the green huge square.
14 x 15 = 210
Find the difference of both squares.
1290 - 210 = 1080
I don't know why there isn't a 1080, but just choose 1086.
Answer:
1,086
Step-by-step explanation:
multiply area of square (36*36) and subtract the not shaded area (14*15)
(36*36) - (14*15) = 1.086

Answer:
10g
Step-by-step explanation:
The apple crumble recipe serves 6 people.
Natalie wants to make it so that it serves 2 people.
6/2 = 3
Which means that the original recipe is 3 times of what Natalie wants.
So if you just divide the original recipe by 3, you can get what Natalie wants.
30g / 3 = 10g
Natalie should use 10g of butter.
Answer:
275g
Step-by-step explanation:
Divide the amount of apple crumble left from the 2x you gave to your friends.
550 Divided By 2= 275g
