How to solve proportion using cross products,k8=14/4

Mathematics
1 answer:
luda_lava [24]3 years ago
6 0
Multiply the variable k times 4 would give you 4k.
Then cross multiply 14x8 = 112

Therefore, you would have 4k = 112.
Divide 112 by 4 to get your answer!

Please help 30 points!!!
just olya [345]

Answer:

Question 1: B = 0

Question 2: 23/2 or 11-1/2

Question 3: 663/6 or 110-3/6

Step-by-step explanation:

Question 1:

(-5²)+(9+4²)=5B

-25+9+16=5B

5B=-0

B=0/5=0

Question 2:

2-7/8×2-6/9×1-1/2

=23/8×24/9×3/2

=23/2

=11-1/2

Question3:

3-1/4×6-2/3×5-1/10

=13/4×20/3×51/10

=663/6

=110-3/6

These cones are similar. find the volume of the smaller cone. round to the nearest tenth.
Kamila [148]

Answer:

Volume of the smaller cone = 8.34 cm³

Step-by-step explanation:

"If two figures are similar, their dimensions will be proportional.

Following this rule,

Ratio of the dimensions of two cones = \frac{\text{Radius of the large cone}}{\text{Radius of the small cone}}

                                                               = \frac{r_2}{r_1}

                                                               = \frac{5}{2}

                                                               = 2.5

Similarly, "ratio of the volumes of two similar figures is cube of the dimensional ratio".

Ratio of the volumes = (ratio of the dimensions)³

\frac{V_1}{V_2}=(2.5)^3

\frac{131}{V_2}=15.625

V_2=\frac{131}{15.625}

    = 8.384 cm³  

    ≈ 8.4 cm³

Therefore, volume of the smaller cone is 8.4 cm³.
