Answer:
Step-by-step explanation:
-4s - 7 = 29 + 5s
Subtract 5s from both sides [-4s - 5s - 7 = 29 + 5s - 5s]
-9s - 7 = 29
Add 7 to both sides [-9s -7 +7 = 29 + 7]
-9s = 36
Divide both sides by (-9) [-9s/-9 = 36/-9]
s = -4
Step-by-step explanation:
If x is the volume of pure water:
Initial + added = final
0.95 (840) + 0 (x) = 0.70 (840 + x)
798 = 588 + 0.70 x
x = 300
840 + x = 1140
You need to add 300 mL of pure water to obtain 1140 mL of the desired 70% solution.
Answer:
C
Step-by-step explanation:
When doing linear equations or quadratics the constant which in this case is +2 means the entire line/parabola is shifted upwards
Answer:
<h2>a) Histograma (histogram).</h2>
Step-by-step explanation:
First of all, a continuous variable only admits whole numbers, not decimals.
Now, in statitics, there are several way to reprepsent some data collected from a survey. The most popular tool are bar-graphs or histograms, they are used to show frequency distributions through graphs, where we use interval classes.
Therefore, the right answer is a.
Answer:Given : Triangle ABC is transformed to triangle A′B′C′
To Find : Which equation shows the correct relationship between the measures of the angles of the two triangles
a The measure of ∠ABC = The measure of ∠A'B'C'
b The measure of ∠ABC = The measure of ∠B'C'A '
c The measure of ∠BCA = The measure of ∠A 'B 'C '
d The measure of ∠BCA = The measure of ∠C 'A 'B '
Step-by-step explanation:
Triangle ABC is transformed to triangle A′B′C′,
ΔABC ≅ ΔA'B'C'
Hence
∠ABC = ∠A'B'C'
∠BCA = ∠B'C'A '
The measure of angle ABC = The measure of angle A prime B prime C prime
The measure of ∠ABC = The measure of ∠A'B'C'
option a is correct
