A chemist needs 90 milliliters of a 57% solution but has only 27% and 72% solutions available. Find how many milliliters of each that should be mixed to get the desired solution.
Answer:
18=18
Step-by-step explanation:
a=90-b
a=50 mL at 4%
b=40 mL at 40%
check
0.04*50+0.4*40=0.2*90
2+16=18
18=18

Answer:
angle Z=20°
side xy≈15.36
hypotenuse≈19.49
Step-by-step explanation:
Find angle z adding the other two angles and subtracting that by 180 to get 20.
(12)tan(20) gets you side xy which is 15.36
12^2+15.36^2=xz^2

If the force is 2500N and the acceleration is 500m/s/s, calculate the mass
Answer:
5kg
Step-by-step explanation:
Here the given force is 2500N and
acceleration is 500m/s²
Now,
F = ma
m = F/a = 2500/500 = 5kg
Thus, The mass is 5kg

Step-by-step explanation:
Pisces is replacing paving stones for her inground pool. Her pool is 10m by 5m and is surrounded by a 1 1/2 border of paving stone. If each paving stone was 25 cm by 40 cm, in theory, how many paving stones will she need?
Answer:
The number of paving stones she needs is 540 paving stone
Step-by-step explanation:
The given dimensions of Pisces' inground pool = 10 m by 5 m
The thickness of the border surrounding the pool = 1 1/2
The dimensions of each paving stone = 25 cm by 40 cm = 0.25 m by 0.4 m
The length dimension of the pool and border = 10 + 2 × 1 1/2 = 13 m
The width dimension of the pool = 5 + 2 × 1 1/2 = 8 m
The total area of the paving stone, [tex]T_A[/tex] = Area of pool + border - Area of pool
∴ [tex]T_A[/tex] = 13 m × 8 m - 10 m × 5 m = 54 m²
The total area of the paving stone = 54 m²
The area of each paving stone, [tex]A_{EP}[/tex] = 0.25 m × 0.4 m = 0.1 m²/paving stone
The number of paving stones she needs, n = (The total area of the paving stone)/(The area of each paving stone)
∴ n = 54 m²/(0.1 m²/paving stone) = 540 paving stone.

A linear function that represents the number of animals adopted from the shelter is compared to a different linear function that represents the hours volunteers work at the shelter each week. Describe the key features of the functions that are needed to determine if these lines intersect.
Answer:
if these lines intersect the slopes must be different
Step-by-step explanation:
A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept.
Answer:
Linear functions (or lines) have really only 2 attributes : The slope (indicating the inclination of the line), and the y-intercept (the intersection with the y-axis) or the x-intercept. Either way, they show the actual position of the line. The lines intersect at one point if they have different slopes. They intersect at infinitely many points, if the slope and the y or x-intercepts are equal (ultimately that means the lines are identical, so every point is an intersection point). If they have the same slope but different y or x-intercepts, it means they are parallel and will never intersect.

Jeremiah ate dinner at 6:17 pm . Before eating, it took him: - 25 minutes to cook dinner - 12 minutes to drive home from the grocery store - 36 minutes to the grocery shop. What time does Jeremiah arrive at the grocery store? Group of answer choices
Answer:
5:04 pm
Step-by-step explanation:
The computation of the time does Jeremiah arrive at the grocery store is shown below:
She ate dinner at 6:17 pm
She took 25 minutes for cooking
She took 12 minutes to drive home from grocery store
And, the 36 minutes to the grocery store
So, the time at which she arrive is
= 6.17pm - 25 minutes - 12 minutes - 36 minutes
= 6.17pm - 73 minutes
= 5:04 pm

use variable `c` for number of child tickets
Write an equation that describes this situation.
Answer:
All of their tickets cost $425.00
Step-by-step explanation:
a= adults c=children
$1700 divided by a=4
$1700 divided by c=2

in a right triangle, if sin(theta)= 8/17, what is tan (theta)?
sin θ = perpendicular/ hypotenuse
tan θ = perpendicular/base
By applying Pythagoras theorem, you get the base as 15
So, your answer is 8/15
